Followers of fashionHow often do you see anything which is new? Often, new products are not new at all. They are old ideas with a new exterior.

So what? If an old idea is a good one, then why not adapt it for today’s circumstances. I heard that same point recently when talking with someone about heat recovery. This technology has been around for decades, but heat recovery went out of fashion.

But, it appears that its time has come again. This month I have seen heat recovery systems in place in shops, and multi-pipe systems coming into the UK which carry out simultaneous heating and cooling.

Heat recovery is coming back into fashion because it is off ering relatively quick returns on investment.

The underlying movement, however, is big companies realising they can make profi ts more easily by driving energy costs (and other costs) out of their businesses. It’s far easier to do that than it is to increase your turnover.

That’s why heat recovery is making a comeback and becoming fashionable again.

EBM PAPST BEGINS WORK ON NEW DISTRIBUTION CENTREGerman fan manufacturer, ebm papst will open a new, €36 million distribution in Hollenbacher at the end of 2016, the company announced recently.

The new, 38,000 m2 logistics centre will ship customer order for fans all over the world. However, the new site was only possible after local government offi cials accepted improvements to roads near the site. The site suff ers from a steep, narrow road, which is diffi cult for lorries to access. Improvements to the road will start in Spring 2016.

Chairman of the ebm-papst group management board, Rainer Hundsdörfer said:

“We urgently need this upgrade if we are to optimise logistics between our locations in Hohenlohekreis.

If this road were not going to be improved we would not have approved this sizable investment in Hollenbach and Mulfi ngen. I am pleased that we will remain faithful to the area and can safeguard jobs in Hohenlohekreis for the long term.”

ebm papst is also building new measuring & testing facilities and administration offi ces at its Mulfi ngen site which will cost €30 million.

HUBBARD PRODUCTS ANNOUNCES MOVE TO NEW SITEHubbard Products, the commercial and transport refrigeration systems manufacturer, is to move its factory and research & development site in Ipswich, Suff olk, starting this November.

The new 50,000 sq ft site at Europark in Ipswich will mainly be used for its manufacturing operations, with 3,000 sq ft used for its sales, marketing and administrative departments.

Chief Executive, Pat Maughan said: “Our Otley site has been a good home to us for nearly

half a century. We will be sorry to be leaving. However, our success at developing innovative refrigeration solutions in collaboration with some of the UK’s best-known retailers and developers of zero carbon technology means that we have outgrown the site.

“Fortunately, we have been able to fi nd a new location that will allow our most important asset our staff , to move with us.”

The company also recently announced a partnership with the Dearman Engine Company to develop a clean energy power unit, which powers transport refrigeration systems.

DAIKIN APPROVES ALTERNATIVE PIPEWORK METHODSDaikin recently approved the use of ‘alternative pipework methods’ on its air conditioning and heat pump systems.

The announcement comes in the wake of Mitsubishi Electric that also approved the use of alternative jointing and pipework methods on their heating and cooling systems. The news will be a relief for companies like Refl ok that have joint systems that use pressure and not heat to connect air conditioning or heat pump units together.

The announcement comes after months of trials and legal processes. One of the main barriers for contractors who wanted to use systems like Refl ok was that the Daikin would void the warranty on the equipment if unapproved materials and methods were used.

The Refl ok system uses aluminium joints and pipe instead of copper. Contractors like using it because the system saves a lot of time during the installation and, because there are no fl ames used when joining pipes together, it is an ideal solution in sites where ‘hot-works’ are not permitted. This is an advantage if there are fl ammable materials on site.

Daikin is enforcing a number of rules for the newly approved jointing and pipework methods to comply with various regulations.

CIBSE ANNOUNCES YOUNG ENGINEER OF THE YEAR 2015CIBSE (the Chartered Institution of Building Services Engineers), announced today the winner of its 20th Young Engineers Awards, Ryan Rodrigues.

Ryan won the crowned Graduate of the Year award, beating off competition from either other talented graduates. The entrants had to give a four-minute presentation themed on how collaboration can be used to improve buildings and building performance.

The Young Engineers Awards promote both graduates and their supporting employers. They recognise hard work, bright thinking and skills in relation to developing a positive future for the built environment.

“We are used to seeing the absolute cream of the UK’s engineering talent at these awards, but the standard was particularly high this year and the bar was raised yet again,” said CIBSE president, Nick Mead.

The awards ceremony was at the Institution of Mechanical Engineers’s headquarters in London, and was followed by the annual ASHRAE president’s lecture, delivered by David Underwood from the US.

CIBSE, ASHRAE and the Institution of Mechanical Engineers support the event, with sponsorship from Andrews Water Heaters, Ruskin Air Management, Schneider Electric, and CIBSE patrons.

The International Institute of Refrigeration (IIR) focused on women in refrigeratio n at its conference in Japan this summer. It revealed interesting insights into the challenges of recruiting more females into the industry.

There is a shortage of qualifi ed people coming into the industry and women are under-represented. With the big changes in legislation coming through the EU and global agreements, the need for skilled, knowledgeable people will increase. Companies will need to fi nd new solutions to adapt to the changing situation in refrigeration.

People attending focused on how to attract more technicians, engineers and researchers into the refrigeration sector. One member of the conference workshop (from ** HVAC & Refrigeration Engineering Ltd (www.hvac-refrigeration.co.uk/index.html)**) put the

solution down to ‘education’. There is more attention needed on the ‘gender imbalance’ in engineering and more investment in making women aware of the opportunity in the sector is important, attendees agreed.

However, other comments illustrated that more female role models will help to attract new people, and that the language used is important to make the industry more approachable. For example, one businessperson at the workshop stated:

“...few women apply for production engineering jobs and yet in environmental research and engineering 80% of candidates are women.”

The outcome of the workshop was that IIR should start an ‘IIR Women in Refrigeration’ group and that it should increase the number of women in its working groups and committees. Read more details here: http://bit.ly/1ZQYL58

Yet other work done by the HomeServe Alliance found that

one in three see intelligent controls as the future for managing heating bills and the same percentage believe that smart homes will help drive down energy bills in the coming years.

What I fi nd interesting about this is not the lack of awareness of the potential cost savings that heat pumps can off er in the residential market – let alone the commercial one. It is the fact that intelligent controls for a home’s heating system are registering as cost saving in the public psyche.

So why mention this in a column focusing on the commercial Aircon sector?

We all know that the controls available for today’s air conditioning systems off er

far more potential than most building operators understand or utilise, whether through lack of training or time.

Yet eff ective use of whatever control system is in place off ers an immediate option for saving energy and therefore costs.

Whether that is simply planning the scheduling more eff ectively to suit a building’s requirements, or limiting the upper and lower limits of a set temperature, taking eff ective control of the controller is the quickest and best way of reducing energy bills.

As a trainer of air conditioning and heat pump engineers, I realise that it is not always possible to remember everything taught on that course you attended last year, or to carry bulky manuals to every site.

That’s why I have just started producing short videos that can be watched on smart phones to highlight the simple things that can be done to programme controllers properly and eff ectively to maximise effi ciency.

The fi rst series focuses on our own PAR31 controller and more are planned, but the basic principles should apply to anyone’s system.

So, whether you are handing over a new system to a building operator, or helping maintain an existing system, make sure you understand how to get the best out of it and your customers will thank you for it.

SIRACH UPDATE14


BASIC WORKING PRINCIPLESMagnetic refrigeration is an emerging, innovative and potential low carbon technology. Due to the increased concern about global warming and an ever increasing energy consumption, the interest in magnetic refrigeration as a new cooling technology competitive to conventional vapour compression cooling has grown considerably over the last 15 years.

The principle of magnetic refrigeration is based on a phenomenon known as magnetocaloric eff ect (MCE). This was discovered by Emil Warburg in 1881 and is related to the property of some exotic materials such as Gadolinium and Dysprosium that heat up when applying a magnetic fi eld and cool down when the magnetic fi eld is removed.

This is illustrated in the fi gure below. It can be seen from the fi gure that by operating the magnet in four steps, it is possible to reject heat and produce cooling. The energy (E =m.Cp.ΔT) generated during each magnetocaloric cycle depends on the variation of temperature ΔT, the mass of material (m) and its specific heat capacity (Cp). This effect is maximal at a specific temperature called the Curie temperature of the material.

16 SIRACH UPDATE


SCHEMATICS SHOWING BASIC WORKING PRINCIPLE OF MAGNETIC REFRIGERATIONThe main limitation of the magnetocaloric system shown in the fi gure is the relatively small temperature diff erence that can be achieved between the cold and hot source. A number of techniques have been used to increase this exchange such as Active Magnetic Regenerator Refrigeration (AMRR).

The principle of this cycle uses a heat transfer fl uid in contact with the magnetocaloric materials (MMC) fl owing from the cold side to the hot side when the MMC is heated (magnetised) and from the hot side to the cold side when the MMC is cooled down (demagnetised).

This progressively increases the temperature diff erence between the cold and hot source to about 20K making the system potentially suitable for commercial applications.

POTENTIAL APPLICATIONSThere are various potential applications. First developments have been oriented to the commercial and domestic refrigeration markets for example display cases, beverage coolers, professional or domestic fridges etc.

However, magnetic cooling can also be completely adapted to other refrigeration applications such as air conditioning, including automotive, cryogenics or in heating applications (e.g heat pumps).

BENEFITSThe demand is likely to be driven by environmental regulations, since magnetic cooling does not use any refrigerant gas but only a water based coolant fl uid. There are no direct CO2 emissions so it fully complies with all regulations such as F-gas in Europe or upcoming EPA regulations in the US.

In addition, the magnetocaloric cycle frequency being typically between 1 and 3 Hz, the rotation speed of the machine is slow and therefore very quiet compared to traditional compression systems.

According to recent research it has been predicted that MCE will have a signifi cantly higher cooling effi ciency (COP) than the present conventional methods, with a potential for a 30% energy saving.

CHALLENGES Even though some product commercialization has been completed, there still remain some challenges:

The primary one is related to the supply of magnetocaloric materials, which are scarce. Therefore reducing material content or identifi cation of new materials would benefi t.

Possibilities for reducing production costs. According to Cooltech the fabrication process has not been optimized yet and costs are still high for allowing a large deployment scale.

Interface optimisations (e.g Heat exchangers) between the devices and the equipment to be refrigerated have to be optimised for maximum effi ciency.

Development of prototypes for various specifi c applications.

CURRENT MARKET DEVELOPMENTAlthough there is a lot of academic work by scientists & engineers from worldwide universities and research institutions the current market development is not fully mature. Some of the companies pushing the boundaries of this technology include Camfridge, currently involved in large EU research project on magnetic refrigeration http://elicit-project.eu/.

NEXTPAC (working on heat pump applications) and Cooltech, according to Cooltech after 3 years industrializing and testing

its magnetic refrigeration system, Cooltech is now introducing a standard product specifi cally adapted to the commercial refrigeration market.

In addition other multinationals from around the world who are working on similar technologies include such as Whirlpool, Electrolux, Astronautics, GE-Appliances, Samsung, Erasteel, Sanden, Chubu, BASF, VAC etc.

VERDICTNot ready yet but One to watch over the next 5 – 10 years.

If you want to experience SIRACH in person, our next SIRACH meeting is scheduled for the 10 October 2015, at Newcastle University Claremont Road, NE1 7RU.

SIRACH will be exploring the topic of - Networks for heating and cooling - opportunities, challenges and new solutions.

On the 1st October the SIRACH Network is visiting Newcastle University and the Joseph Swan Centre for Energy Research. Delegates will visit this interdisciplinary research centre, known to deliver holistic, cutting-edge research and fi nding new ways of meeting the growing energy needs in an environmentally-friendly and sustainable way.

APPRENTICE MIND-SETWhat about the mind-set of a potential apprentice? Whilst not universal, we do see that there can be unrealistic expectations of reward for performance. Apprentices seek the fastest route to the solution without caring about the process or even understanding how they arrived there. The solution is produced without checking it for being realistic. Apprentices worry about getting it right when they are not given the answer to work to and constantly ask for reassurance. As a result of that they work very incrementally. This can be a product of the school “system”.

They can also lack staying power and expect things to be neatly sewn up by pressing a button on a computer and may be unable to complete work-based tasks on a computer despite being

supposedly IT savvy. These traits aff ect employment in many sectors, not just engineering, and echo comments made by the CBI and others.

This is possibly the toughest challenge faced by potential employers and training providers for which there are no easy answers. An element of “tough love” applies here. When a student sees work thrown in the scrap bin after one hole was drilled incorrectly in a work-piece that took a week to produce, that does test their ability to keep going. It makes them realise they have to concentrate for longer periods of time and gain a realisation that the teacher is not going to help them at every stage.

As HETA has a rigorous recruitment process, the young people we train tend to be more

focussed. This is not to say we don’t have apprentices who exhibit some of the traits shown above at some stage, but the low student \ instructor ratios, the working environment and regular reviews mean they are left in no doubt that they need to improve.

CAREER ADVICESchools career advice has been slated as being out of touch and students may not have realistic expectations of the requirements of particular workplaces. This is not the complete picture and it depends very much on who is in charge at schools and 6th form colleges and what previous experiences they have had in contacts with companies. Parents and siblings will also colour opinions.

Selecting and Retaining ApprenticesSteve Dixey, Mechanical Instructor from engineering training business, HETA, explores how to choose and keep apprentices.

TOUGHEST CHALLENGE

FACED BY POTENTIAL

EMPLOYERS AND TRAINING

PROVIDERS FOR WHICH THERE ARE NO EASY

ANSWERS.”

19TRAINING


Schools may view engineering as an “easy” route compared to academic pathways even though the requirements for maths, science and other skills are higher than ever. We have invited groups of teachers into the training centre, given them presentations on engineering and showed them what goes into engineering training and the sorts of things different trades would be doing.

There are perception gaps as some teachers may never leave academia in one form or another and go from school to university to a teaching career. As with apprentice training, employer engagement with schools may bridge this gap. Both parties may say “We can’t spare anyone” but there has to be a meeting of minds and mutual respect at some stage if schools are going to produce useful future employees and employers appreciate what hoops schools and colleges have to go through in order to bring their student up to the requirements set by ministers in order for them to keep funding.

Technology teachers are a possible route into engaging with schools and 6th form colleges as they may be more appreciative of what they are shown.

RECRUITMENT AND RETENTIONHETA recruit on behalf of their client companies or can filter likely candidates who will then be presented to companies for selection. As they are interviewed by engineering staff, we may have a better feel for suitability. Given the very high retention rate, HETA feel that they have taken the right approach. The interview looks for initiative, for knowledge of basic engineering concepts and an ability to express themselves clearly.

Potential apprentices are invited in to practical workshop sessions. Attendance at and performance in these also have a bearing on potential suitability.

HETA also offer traineeships to students who do not have a sponsoring employer. They cover exactly the same training pathway as sponsored apprentices and HETA actively seek employment opportunities, with very high success rates. These potential apprentices come “work ready” with both practical NVQ Level 2 and Level 3 technical certificate qualifications. We do this as some FE colleges back out of practical workshop training to offer classroom-based technical qualifications that are no real use without the practical skills to back them up. This training also eats into the funding that comes with school leavers, stripping away part of that funding and leaving a gap that has to be filled by completing practical skills training and assessment for an NVQ 2.

We do get students who are asking for jobs and looking to gain an NVQ 3 via an engineering apprenticeship with an employer but get told their technical certificates such as BTEC are no use unless they first undertake an NVQ 2 pathway. As funding has been used to get a Level 3 BTEC technical certificate, that student is less attractive to cost-conscious employers and engineering training providers. Exceptional candidates may get taken on and their employer may plug that funding gap but that is the exception rather than the rule.

WHAT DO EMPLOYERS GET?What employers need to appreciate is that apprentices can

be a real asset if they are trained properly. Yes, there are hiccups on the way and yes, there is a possibility of losing a very small percentage on the way.

Employers need to check that the funding available is used correctly and that training providers are not picking the low hanging fruit of classroom-based teaching to access funding. The best route is still to pick early after GCSE’s or A levels to maximise training incentives.

MATURE APPRENTICESFinally, what about “mature apprentices”? Unfortunately, the funding is often slewed towards young people and it is not an easy task to secure funding. We feel it is wrong to discriminate in this way as older workers may have a better attitude to work, be more focussed in their approach and generally progress faster through the NVQ assessment process. The only catch may be that academically they may struggle after being away from a learning environment for a period of time. This may be overcome by the use of internet access to learning resources at a training provider coupled with peer support and access to face-to-face or peer support. HETA have supported offshore workers in this way.

TRAINING22


The impressive new offices, right next to the historic motor racing circuit near Weybridge

in Surrey, house an equally impressive new training academy that was opened on the day by LG’s UK President Mr Ki Kwon. The centre includes areas for trainees to get ‘hands on’ with all the LG products – air conditioning, heating and the user interfaces that set LG equipment apart from its competitors.

LG Opens Up New UK Training Academy to Help Installers and Contractors

LG Electronics opened their new training academy in Weybridge in October. The ACR Journal team went to visit the new venue in Brooklands, Surrey and interviewed their Technical Manager, Mark Richardson about their courses.

This says a huge amount about where our priorities lie.

“We provide exceptional equipment and in order for this to deliver the performance and on-going benefits to the end users who invest in LG quality, it’s vital that the equipment is installed properly and maintained to deliver the highest possible levels of efficiency.

“We want to see an ever expanding number of engineers coming on our courses and we provide this training free of charge. It’s an integral part of what we offer and it’s vital that it’s taken up.”

The launch of the LG Si – Specialist installer - programme has moved the training agenda forward a number of notches, such

that the LG Distributor customers are arguably the most highly trained individuals in the sector. This programme will continue to be rolled out in 2016 when LG will see large numbers of new engineers and an equally impressive number of existing team members heading back for further training and top-up training to keep them at the cutting edge of LG technology.

Visitors to the open day saw the full range of LG equipment as they were shown around the academy – including the Therma V ranges of air to water heat pumps which are taking the sector by storm, the Multi V VRF range of equipment, the engineered solutions on offer from LG and

Jody Lees, Head of Air Conditioning and Energy Solutions in the UK welcomed the visitors and, stressed just how vital training is to LG as part of the package it offers:

“We’ve trained more than 3,000 people in the past seven years and in the past four years we’ve seen the number coming through our training courses almost quadruple.

the wide range of user interfaces from simple controls to the most advanced options that can interface with the most complex of building controls systems on commercial properties.

WITH MARK RICHARDSONWill asked about Mark’s role and what it involves:

I look after the technical department. I manage our team of field and office engineers. Also, specialist installers and approved installers. I run the ‘man management’ of the technical department. To make sure we are providing world class customer service.

I do my share of commissioning and work with the sales team visiting consultants too.

With LG’s wide of heating and cooling solutions, it must be quite a challenge to keep the installers up to date with new products, solutions and changes?

The whole point of the academy is to improve the skills of our installers. And to show the structure we have in place to help and support engineers. But, also to show the technological advances of the products and where they have come from.

The VRF Multi IV we now have is a very high-end product which has developed over each version. We want to show installers where it has come from and to help support them going through the stages of the training.

We have dedicated courses to make sure the engineers have the right skills and they are ready to install the equipment in the field.

How experienced do engineers attending your courses need to be?

There is a wide range of skills and experience in the industry from the school leavers and junior engineers to engineers who have been in the industry between five and ten years. They might be installers but, for example, they might not have the skills to full diagnosis, fault finding and commissioning.

What skills are most of your customers asking for?

It’s the commissioning of products and the services we offer compared to other manufacturers.

What they use from our services, especially on VRF projects, we have a pre-commissioning inspection. We help them manage all VRF projects. We do the commissioning visits for them, sometimes we charge.

Once they are commissioned, within 30 to 90 days we will do a post-commissioning visit which is free of charge to make sure the system is operating correctly.

However, it’s down to what customers want. We want to support them in any way we can.

How much of your training is theoretical or practical?

For VRF, for example, the first day is very academic, including specification, and learning about the design features. It will help you about learning the system correctly.

The second day covers commissioning in the morning and troubleshooting systems in the afternoon.

Is that data side of your products and services becoming more important?

Yes, this is a big topic.Our monitoring and diagnostic

tool, LG MV, comes in a laptop version which you can plug directly into the VRF unit. And we have WiFi version which works with Android and Apple smartphones.

These help the engineers understand anything which is either refrigerant or electronics based so they can monitor it. The LG MV works with the VRF products and Therma V heat pumps.

What extra can people coming on LG courses benefit from by coming on your courses?

They don’t have to come on courses to benefit from two recent announcements. We’ve introduced a 10-year warranty on compressors under 10kW. This reassures our customers. In addition, we now have a 7-year warranty on parts and labour for the Therma V heat pumps.

TRANSPORT REFRIGERATION26


One million refrigeration

units creates an environmental and health impact equivalent to approximately 56 million diesel cars.

Analysis undertaken by Dearman, the clean cold and power technology company, has highlighted the damaging economic, health and

environmental impact that cooling of refrigerated vehicles is having across Europe.

The research, presented in Brussels on 29th September, found that the 1 million transport refrigeration units on European streets have the equivalent impact on air pollution as up to 56 million diesel cars.

Hundreds of thousands of refrigerated vehicles run on European streets every day –delivering cold and frozen goods to restaurants, supermarkets, warehouses, homes and hospitals. Unregulated secondary diesel engines often power the cooling in these vehicles are which are ineffi cient and disproportionately polluting.

Transport refrigeration units can emit up to 29 times more potentially carcinogenic particulate matter and six times more NOx than far larger, modern diesel truck engines. They can emit up to 165 times as much particulate matter and 93 times as much NOx as the latest diesel cars.

A HIGH COSTLaunching the report in Brussels, Professor Toby Peters, Chair in Power and Cold Economy, University of Birmingham and CEO of Dearman, said: “Until now, nobody has given transport refrigeration units a thought. We all shop at food stores, eat in restaurants or have chilled and frozen food delivered, but the impact of transport refrigeration units has never been investigated, let alone addressed. They are unregulated, use out-dated, fossil-fuelled technology and are disproportionately polluting. What’s worse, their pollution is concentrated on city streets where it does the most damage to our health.”

He added, “With 400,000 people dying prematurely every year in the EU as a result of air pollution, we simply cannot aff ord to ignore these hidden polluters any longer. Awareness is growing and the policy landscape is just beginning to change,

but action is needed now to prevent further environmental damage.”

The research also fi nds that pollution from transport refrigeration units could cost EU countries 22 billion euros over the next decade, as the EU fl eet grows by 20% to 1.2m by 2025. If nothing is done, the environmental and health impact of emissions will impose an annual burden of 2.5 billion euros by 2025.

This year alone, the cooling of refrigerated vehicles in the EU will emit 13m tonnes of CO2e; 40,000 tonnes of NOx; and 5,000 tonnes of particulate matter – equivalent to the emissions from 56 million diesel cars.

The report authors base their projections on a conservative assumption that the refrigerated vehicle fl eet will grow by 1.5% per year. However, other studies have predicted that annual cold chain market growth could be as much as 12% YoY.

The signifi cance of refrigerated vehicles to modern supply chains is palpable – but with the growing popularity of online grocery shopping and the shift from out-of-town supermarkets towards local convenience stores, demand for transport refrigeration – and its detrimental impact on air quality – is set to increase, unless a zero emission solution is adopted.

27TRANSPORT REFRIGERATION


THE KEY FINDINGS OF THE REPORT:• 1 million transport refrigeration

units currently operate in the EU (180,000 in Germany; 150,000 in France; 84,000 in UK)

• Diesel transport refrigeration units in the EU produce an air quality impact that is equivalent to approximately 56 million diesel cars (10 million in Germany and 8.4 million in France)

• Environmental impact is emission of 13m tonnes of CO2e; 40,000 tonnes of NOx; and 5,000 tonnes of Particulate matter (PM)

• The environmental and health impact of emissions will impose an annual burden of €2.5 billion by 2025

• Transport refrigeration is currently unregulated, providing no incentive for innovation

• Transport refrigeration units give off up to 29 x more particulate matter (soot, smoke and liquid droplets) and up to 6 x more NOX (Nitrogen Oxides) than a modern diesel truck engine (Euro VI)

• That’s up to 165 times as much particulate matter and 93 times as much NOX than a Euro6 diesel car

• A zero-emission alternative is to use a liquid nitrogen powered Dearman engine to provide both clean cold and power – a solution that creates no localized emissions and generates substantial CO2 savings

• Dearman’s transport refrigeration system will be in on road commercial trials in the UK later this year, with European trials set for early 2016. Commercial manufacture will begin in 2017.

Dearman has developed innovative, zero emission technologies to deliver clean cold and power. At the heart of the Dearman technology portfolio is the Dearman engine. A novel piston engine harnesses the rapid expansion of liquid air (or liquid nitrogen) to produce zero- emission power and cooling for a range of applications, including transportation, buildings and food distribution.

Dearman is rapidly developing a range of applications for its technology. The most advanced is a zero-emission transport refrigeration system, which will help to signifi cantly reduce emissions and meet fast growing demand for refrigerated transportation, without creating signifi cant environmental consequences or burdening operators with additional operating costs.

Dearman’s system is expected to off er the lowest total cost of ownership on the market.

The Dearman transport refrigeration system is currently undergoing on vehicle trials, will enter commercial trials later this year, and will begin multi-country trials next year.

WHAT IMPACT IS ENVIRONMENTAL LEGISLATION HAVING ON YOUR BUSINESS?F-Gas legislation not only infl uenced the static refrigeration but the transport industry too.

The overall EU target is to reduce the potential impact of F-Gas by 79% by 2030. Within the rules of the F-Gas, they set a Global Warming Potential (GWP) limit of 2,500 of it by 2020. But, and this is a high ‘But’ in transport is that is applies to systems above 40 tonne refrigerant charge equivalent.

If you have R404A, all systems with more than 10KG will fall under the new F-Gas legislation. For other parts of the GWP level, in transport, we were let off on this one, because most of the systems in the fi eld today are below 10KG of refrigerant.

In a sense, the transport industry was not impacted by the GWP level of HFC. But, having said that, F-Gas is not only looking at the GWP level, it is also looking at how you handle HFC. So, if you service a system, you need to register what you are

recovering from the system, and you need to register the new charge you put in the system. There is a full aspect on the service side and our Thermo King dealers will need to register all of their HFC movement. In addition, they will have to perform a yearly leak check on all systems.

We are impacted for part of the F-Gas but not for the time being (I am sure this will change), but not on the GWP level of the F-Gas. Having said that, at Thermo King and Ingersoll Rand we have our own commitment to reduce our greenhouse gas emissions, which includes the effi ciency of the system, for our products by 50% by 2020.

We are also looking at how we produce our products. We aim to reduce our greenhouse gas emissions by 35% by 2020.

THAT MUST BE AFFECTING YOU THINK ABOUT YOUR PRODUCTS AND YOUR SERVICE BECAUSE THAT IS A BIG COMMITMENT?Yes, one immediate action we have decided that even though we are not directly impacted by the F-Gas legislation, as mentioned, we announced that we will launch a new refrigerant that will replace R404A

called R452A. We have worked closely with DuPont on the development of R452A for the last three years.

This refrigerant has a GWP of 1940, which means we are already cutting our potential emissions in half. We have introduced R452A on all our trailer products for the time being. Our truck range will also have use this new refrigerant.

We have also looked at how we can reduce the charge within our systems. By implementing new technologies, such as micro-channels, even in transport refrigeration systems we have been able to reduce the charge in our systems by, on average, 30%.

If you add the 30% and the 50%, we have an average GWP reduction of 69%. We are well on track to deliver what the EU is expecting from the industry in 2030.

That’s not the end of the story and we continue to work on developments to reduce our GWP. But, we always need to look at the overall impact.

The industry is challenging and we need to create solutions which not only benefi t the environment, but they are effi cient and aff ordable for our customers.

IN THE CONTEXT OF THE INDUSTRY, MARGINS ARE ALWAYS TIGHT SO IT MUST BE A DIFFICULT BALANCE TO MEET FOR YOUR CUSTOMERS?We need to think out of the box. We’ve made a very nice fi rst step using R452A and micro-channels. This change made little change to the price of the new units. The units are a little heavier (15KGS). However, we need to make it feasible to buy for our customers.

Three years ago, we showed a CO2 closed loop system. CO2 has a GWP of one, and other natural gases have very low GWP. But, all these natural refrigerant gases required a huge change in the refrigeration system; they had a big change on the effi ciency. To make up for the effi ciency loss of adding CO2 you need to add complexity to the system.

I am not saying that it adds a lot in cost but it destroys a lot of the effi ciency because you need more power to run the new system. You need to fi nd a balance.

We need to keep in mind the overall emission of our system. R452A and micro-channel enabled us to have an immediate impact on our emissions.

But, R452A is a refrigerant which is useful for upgrading existing units. Customers can bring their existing R404A units to one of our dealers and they could upgrade it to the new refrigerant.

WHERE ELSE ARE YOU USING THE R452A?Yes, we are using three refrigerants in Thermo King.

The most common is 404A. We use R134A as used in your air conditioning. And, R407C in our bus business.

THE PHYSICAL CHALLENGE OF ONE YOUR PRODUCTS ON A TRAILER IS MOVING AROUND. YOUR EQUIPMENT MUST HAVE TO BE ROBUST TO PUT UP WITH THE CONDITIONS.Yes, we have an R&D centre in Prague where we have a we have

a ‘Multi-Axis Shaker Table’ to test our products through a one million kilometre test. We push to the extremes not only for leaks but also for the other components to ensure our customers enjoy the quality and reliability of the products for some years.

On average, you can see trailers running after nine years, or some of our customers are pushing to 12 years.

They have to put up with a lot of diff erent conditions and that is a big diff erence between static and mobile refrigeration units. Movement, yes, but our systems could run in Kuwait or Sweden. And you could maybe tailor the off er for a customer who is not going to see temperatures of 45 degrees in Sweden. But, their units could travel from there to Spain or Morocco.

We put very high standards on our ambient conditions and the rules for our products ensure they run from minus 30 degrees to plus 55 degrees.

THAT’S PRETTY CHALLENGING TO TEST AGAINST AND PROVIDE A SOLUTION FOR?Yes, and for some specifi c market demands, we have to restrict the ambient demands for some distribution. For example, if you have to reduce the noise level you have to further encapsulate the unit.

Another diff erence between transport and static is that most of the time a static application is that you know where it will be installed. And, secondly, you know what the set point will be.

It’s static not only on where you know it is installed, and whether it is a deep frozen or fresh warehouse.

Our customers don’t just transport fresh produce, for example. They have to fi nd what they can to transport and that might be frozen today and tomorrow it is fresh.

In that case, our customers have a set point that goes from +18 degrees to -30 degrees. That’s another challenge.

Imagine the challenge. In transport refrigeration, it is completely diff erent set of challenges to the static market.

WHAT’S NEXT FOR THERMO KING?It’s on everybody’s objectives to continue reducing emissions, from top to bottom. We’ve made this clear.

Thermo King also recently acquired Frigoblock. We believe this will help us to deliver an advanced portfolio for truck and trailer with non-diesel technology.

Some Frigoblock systems use a generator installed on the vehicle. That’s something in the future that we think will enable us to off er an advanced portfolio across the two brands on non-diesel technology.

We have a Cryogenic technology where we use technology that needs no compressor or engine. You use CO2 as the energy source. You expand liquid CO2 and remove the heat from cargo load. That is going well. There are logistic challenges. But that is another realistic solution in our portfolio. We are doing the right things to tackle the future.

There is life after R404A. If you haven’t done so, or are

thinking of doing so, you should stop working with R404A – viewed as the go-to refrigerant by many over the past 15 years – as soon as possible.

The phase out of high GWP (Global Warming Potential) HFCs means that the door is closing on R404A and, while it is freely available at the moment, the trend going forward suggests it will soon become increasingly less so and in turn more expensive.

The real pinch points are still open to debate but to my mind it will be 2017 and 2018. There is a big problem looming and this will leave many with a decision to make on what they should do to replace R404A. Some end users are still sitting on their hands but there is a way forward and help is there.

NEW ENTRANTSUp until now R407A and R407F (Genetron® Performax™ LT) have been popular alternatives to R404A but two new low GWP refrigerants have entered the stage and the good news is that these new boys can make a real diff erence to carbon footprint and energy effi ciency.

Opteon XP40 (R-449A) and Solstice N40 (R-448A) are welcome additions to the refrigerants’ market place. They also have a lower GWP than R407A and R407F – around 1400 rather than 1800-2100, and can improve energy effi ciency.

Although lower GWP has yet to emerge as a factor in refrigerant pricing, you can be sure it will be a selling point in the future. Higher GWP gases will get more expensive and so that margin will grow in signifi cance.

A-Gas Managing Director John Ormerod examines the credentials of new low GWP and energy efficient refrigerants XP40 and N40

XP40 and N40 have a lot to be proud of. Their low GWP credentials – a more than two-thirds reduction on R404A – makes them an obvious choice for those considering a change of refrigerants. They are also very closely matched to R404A in terms of their refrigeration capacity. They are suitable for medium and low temperature systems and it is fair to say that there is little between them in terms of performance.

TEMPERATURE ADVANTAGEA big advantage over R407A and R407F is that they have lower discharge temperatures. In some cases if someone was to switch from R404A to R407F they may need to do more than just change the gas and introduce some form of discharge temperature control on the compressors. You should not need to do so with XP40 and N40 in most cases, which in turn saves time and money where it matters.

This means the compressor is also likely to last longer. R407A and R407F discharge temperatures can be high,

straying into that area where the compressor manufacturers begin to get a little nervous. For instance, at high temperatures the oil in the compressor can begin to breakdown which will have an aff ect on reliability. In most situations with XP40 and N40, the discharge temperatures are well below 100°C and you will not slip anywhere near this dangerous territory.

MORE EFFICIENTEnergy effi ciency is also a plus point. There are savings of between fi ve and ten per cent to be made and if you are running a large supermarket or cold store operation this is not to be ignored. The bottom line benefi ts soon add up.

Large supermarket chains are already running trials to gain experience of using these new refrigerants. Reports suggest that they are going well and the rest of the supermarket industry is beginning to sit up and take note.

With the F-Gas Regulations taking a fi rmer grip on the industry there’s

no time to lose in switching to lower GWP refrigerants. Although, I am led to believe that contractors are still installing equipment using R404A – something I fi nd puzzling with the ban on servicing high GWP equipment coming into eff ect in 2020.

Many industry commentators agree that there’s a major problem looming but some heads are still fi rmly stuck in the ground because shortages have yet to take hold. 2016 will soon be upon us and with it the fi rst step down in the HFC quota. Refrigerant supply will be reduced by seven per cent and the following years will only see sharper falls.

So the big shock is likely to happen in 2017 or 2018. Short-term thinking on refrigerant use is not the answer. The rate of change is speeding up and I believe in the next fi ve years this will have the most profound eff ect on our industry. It’s up to all of us to ensure that we don’t miss the bus.

Here, Martin Passingham, Product Manager at

Daikin UK analyses the results of an industry survey demonstrating the impact of the R22 ban on UK AC contractors and the reasons behind the slow uptake of new refrigerants amongst a majority of customers.

Following the ban on replacing R22 refrigerant in existing air conditioning systems in January

2015, replacement refrigerants such as R32 and R410a have slowly been increasing in popularity within the HVAC market. With much lower global warming potentials (GWP), the refrigerants are not only more environmentally friendly but they are also more energy effi cient, resulting in a lower refrigerant charge and the potential to manufacture smaller units.

Although the phase down of high GWP refrigerants has been underway since 2000, the fi nal ban on topping up or replenishing R22 in existing systems was expected to impact widely on the air conditioning sector and on all AC engineers using the refrigerant.

Eight months after the ban, Daikin UK undertook a survey of AC contractors and installers to establish the impact of the R22 ban, and to understand the barriers installers face when moving toward using new, lower GWP refrigerants.

SHEDDING LIGHT ON THE CHANGESProducing enlightening results, more than half of those surveyed believe the R22 ban is aff ecting their business, with more than

Since the 31st December 2014, it has been illegal to top up or replenish an AC system using R22 gas. Many manufacturers have continued to supply spare parts for systems originally sold as R22 but with all sources of the refrigerant now banned, installers are facing a dilemma in how to deal with their customers who are still using these systems in their buildings.

a third of all businesses under the impression that 50 per cent of their customers are still to convert their R22 systems to an alternative refrigerant.

Adding to this, the majority of installers conceded that their biggest challenge is that customers are unwilling to change their AC system at this time, with a shocking 78 per cent waiting for their existing system to reach its end of life or breakdown before considering a replacement refrigerant.

This is having an impact on the number of opportunities available for AC installers, as although many are ready and trained for using, for example, R32, the opportunities to upgrade systems from using older refrigerants are scarce.

THE REPLACEMENT DILEMMA

“As well as being more energy e� cient, R32 is a cost-e� ective

replacement for R22 and as a single component refrigerant easier to reuse and recycle.”

Marti n Passingham

32-34 Daikin.indd 32 26/10/2015 17:52

33REFRIGERANTS 33REFRIGERANTS

COMPLIANCE CHALLENGESIt also presents a compliance and legal issue for installers, as although it is legal to replace components of R22 systems such as for example, a compressor, recharging the system with new, recycled or reclaimed R22 refrigerant is illegal. This means there is a high risk of system failure as there are limited support options available to maintain well running R22 systems.

Customers therefore need educating on the benefi ts of upgrading to newer refrigerants such as R32 and R410a. As well as being more energy effi cient, R32 is a cost-eff ective replacement for R22 and as a single component refrigerant easier to reuse and recycle.

When considering the most important features of alternative refrigerants, opinions of installers were split; with 23 per cent believing energy effi ciency is the

most important factor, and 23 per cent also considering aff ordability to be an important.

SPLIT ON SAFETYOne of the most important fi ndings of the survey was that only 15 per cent of respondents saw safety as an important consideration. Categorised as an A2L refrigerant, R32 is as safe as many gases already used by a majority of installers.

With more than 75 per cent of installers choosing R32 or R410a as their preferred alterative, it is clear that installers are embracing the move toward more environmentally friendly solutions.

The diffi culty the UK air conditioning sector now faces, is the challenge of leading customers toward more effi cient refrigerants, rather than waiting for their current ineffi cient systems running R22 to break down.

As a forward-thinking manufacturer, Daikin UK is providing all of its installers with cost eff ective and highly effi cient alternative refrigerant solutions and the necessary training to enable contractors to off er them to their customers. To assist contractors in persuading their clients to update their climate control systems with newer refrigerants, manufacturers should also be providing a range of training, information advice and documentation to help them make informed decisions for their clients.

In the meantime, its worth reinforcing the facts: end-clients can benefi t from lower running costs over the lifetime of the system, extended warranties, renewed confi dence in an eff ective system and a dramatic reduction in a company’s carbon footprint by choosing full replacement of their R22 systems.

Name and job titleKaty Eccleston, Head of Contractor Sales, Hawco Ltd

Education: Where did you study and what course/diploma/degree did you gain?Having studied for my GCSEs at Settle High School in North Yorkshire, I decided to continue my education at Craven College in Skipton. Interested in business I decided an Advanced GNVQ in Business Studies would be the perfect introduction to a successful career – although I wasn’t sure exactly what role I wanted to pursue.

At 20 I started working for Pillinger Air, an Air Conditioning Contractor in Chester. My fi rst role was as an offi ce junior and the business was kind enough to pay for me to continue my education at Craven College, this time to secure an HND (Higher National Diploma) in business.

Are you a member of any industry associations?Not applicable, although I am a member of Laithwaites wine club

Who do you work for?I recently joined Hawco Ltd from Daikin UK. As one of the UK’s most successful supplier/partners to the OEM refrigeration market, the opportunity and challenge at Hawco to expand the company’s presence and reputation among aftermarket contractors was too good to turn down. The move also means I can gain knowledge and experience beyond Air Conditioning with the businesses leading portfolio of Refrigeration products. I’m responsible for the North of England and also manage a great team of Contractor Sales Engineers across the UK.

What attracted you to the industry?At Pillinger Air I worked my way up through internal sales/quotations and then fi nally into a fi eld sales role at Daikin. David Petty was my infl uence

and mentor in the early days and encouraged and supported me to progress. I loved being out on the road in a customer facing role. The people working in the industry are great and the friendships and contacts I have developed over the years has helped to continue my passion for the industry.

What do you specialise in now? Or, what type of projects do you work on?I specialise in Air Conditioning having had 12 years’ experience within the industry. At Daikin I was involved in everything from splits for a chain of shops or restaurants to a full VRV project in a multi-level building, and although I’m keen to continue my work with AC, I’m also excited about working on a variety of new projects.

What do you know now about the industry which you wished you had known before?The speed at which the next generation of refrigerants is evolving. Before I came to Hawco my focus was in Air Conditioning, which only used three main refrigerants at the time, compared to almost three times that used in refrigeration.

What excites/interests you about the industry and your part in it now?The diversity of customers and projects.

37WOMEN IN ACR

What would you say to other women who are considering coming into the ACR industry?I would say the same to anyone thinking of entering the industry, male or female. Every day is challenging and diff erent, no application has the same requirements or outcome. Be ready to work hard, adapt to the

needs of your client, and don’t be put off by the competition. If you’re hard working, love meeting people and forming relationships that last, I would recommend a fi eld sales career in the industry. It’s highly rewarding and the technology is constantly changing, keeping you on your toes!

Where do you see your career developing?My focus for the moment is developing Hawco’s contractor sales across the UK, but in time, who knows. I’m an ambitious person and will continue to work my hardest to achieve my goals.

What are the challenges of this industry?The changes in environmental legislation can be challenging, especially the R22 ban and transitioning into R407c and then R410a. The economic

downturn was a big challenge for the industry as a whole, as it caused a reduction in new buildings - but in any job there are going to be situations that are out of your control. It’s important to remain positive. A good attitude can see you through.

What are the benefi ts of being in your role (e.g. travelling, variety, monetary?)I enjoy how varied my role and the people I work with are. At Hawco I’m involved in our marketing eff orts and even the product lines we stock. One day I could be in the offi ce working on our latest advertising campaign or meeting with my team of fi eld sales engineers, the next I’ll be on the road visiting customers, contractors on site or even visiting a supplier’s factory in Europe with clients.

Sustained growth

in the chilled snacking market, together with consumer appetite for increasingly varied and exotic food to go, has led to a much broader off er from

supermarkets, convenience retailers and forecourt outlets.

A typical retail refrigerated snack cabinet will now display a wide range of sandwiches, wraps, savoury pastries, pasta dishes,

salads and even sushi. Many of these snacks contain high risk ingredients, such as pork, poultry, fi sh and salad. Invariably, these foodstuff s will not be re-heated prior to consumption, meaning that storage and display at the correct temperature is critical to food safety and quality.

Nobody wants to eat a salmon sandwich or sushi, which has been stored at too high a temperature and is liable to the proliferation of harmful bacteria and toxins. At the other end of the scale, a salad or pasta dish, in which ice crystals have formed will be equally unpalatable.

WHAT DO THE RULES STATE?EC Regulation 852/2004 and The Food Safety and

Hygiene (England) Regulations 2013 state that foods likely to support the growth of pathogenic micro-organisms or the formation of toxins should be held at or below +8°C.

Some authorities, including the Australian Victoria State Government, advocate that the maximum storage temperature for high risk foodstuff s should be lower at +5°C. The majority of refrigeration equipment manufacturers and grocery retailers accept an operating temperature range of -1°C to +7°C (M2) as safe and suitable for the display of chilled snacks, but to eliminate the potential for ice crystal formation it is preferable to avoid sub-zero temperatures.

Catarina Marques, from Adande Refrigeration, recently presented a paper on minimising food moisture loss in professional cabinets at the 24th IIR International Congress of Refrigeration in Yokohama, Japan. The congress also held a debate on the cold chain, food quality and food safety. Catarina examines the issues relating to the refrigerated display of food to go in the grocery sector.

TIGHT TEMPERATURE CONTROLSHowever, research in the foodservice sector, including trials at Westminster Kingsway College, has demonstrated that food held at a tighter and more stable temperature range will stay fresh for longer periods.

In terms of the retail snacking market, this translates to a more enjoyable product for the customer and less merchandise price discounted or thrown away due to deterioration in quality or appearance. To compound the issue we are also aware that some snack food refrigerated cabinets on the market did not achieve the appropriate M2 operating temperature range of -1°C to +7°C.

To establish the facts, Adande commissioned independent like-for-like tests to compare the temperature range of a standard open front multi deck refrigerated cabinet with that of a similar case modifi ed with the Adande Aircell air fl ow management system. The

trials were carried out under BS EN ISO 23953, which is the accepted industry standard for the testing of refrigerated display cases, at ECH Engineering’s state-of-the-art laboratories near Bristol.

After stable state running for 24 hours, the temperatures of product packs in each case were monitored over a further 24 hour cycle. The case modifi ed with the prototype Aircell system demonstrated a 40% narrower temperature range than the standard model, with no product pack readings recorded in the warm zone, which supports bacterial proliferation, and no readings in the sub-zero zone, which causes ice crystal formation.

By contrast, product pack temperatures in the standard case included measurements in both the dangerous warm zone and the sub- zero zone.

SAVING ENERGY TOOIn addition to its accurate and stable temperature

characteristics, Aircell also demonstrates signifi cant energy savings compared with conventional open front multi deck refrigerated cabinets.

The high integrity of the Aircell multiple air curtains signifi cantly reduces cold air spillage from the cabinet, reducing energy usage by up to 30%. Because Aircell reduces the spillage of chilled air from the cabinet, the impact of cold aisle syndrome is substantially limited for an improved environment for shoppers and staff . It also reduces retailers’ dependence on heating regimes and cold air retrieval systems.

Dr Catarina Marques is Research & Development Manager at Lowestoft based Adande Refrigeration and is also a Knowledge Transfer Partnership Associate at London South Bank University. She is a graduate in Food Science and Engineering at the Polytechnic of Coimbra in her native Portugal.

COMPANY PROFILE40


Since launching in 2002, air conditioning distributor Cool Designs Ltd has carved out a distinctive niche in the UK market.

POLICY LEADERIn addition to achieving near-meteoric growth (it is among the fastest-growing 50 companies in the North East), the company is something of a pioneer in the fi eld of environmental policy,

being the fi rst UK distributor to become a certifi ed carbon neutral business – ahead of the leading manufacturers.

“All our discussions with customers tend to focus on the effi ciency of equipment and its environmental performance. It seemed at odds with the distances our products were shipped – by sea and land. We wanted to do something to off set this, so we

could hold our heads up in these discussions,” says Darrel Birkett, the company’s founder and owner.

CDL supports forestation projects in Tanzania, authenticated by The Carbon Neutral Company, as well as planting and managing its own woodland in the UK.

It has also taken a leading role in implementing F-Gas policy, requiring customers to provide proof of refrigerant handling competence before this became a mandatory requirement across the European Union.

This proactive stance has helped CDL secure coveted industry awards for Distributor of the Year Award on more than one occasion.

GROWING PRESENCEThe company’s branch network has also grown rapidly. After being established in Sunderland, the company soon expanded with a branch across the Pennines in Warrington. Since then, growth has

seen further expansion both north and south, with a branch in East Kilbride and – most recently – in Cannock, opening the way to the south and London.

Turnover in its fi rst year was £650,000. This year, sales will be in the region of £10m. The husband-and-wife-led launch team has grown to a staff of 20 people. Key to success has been the choice of strong brands and a commitment to excellent service.

Toshiba is the mainstay for CDL at the premium end of the market. Its best-selling systems are Toshiba’s Digital Inverter wall-mounted units and cassettes. “The engineering quality, innovation and brand strength of Toshiba are superb, and it is the bedrock of our business growth and success,” says Darrel.

It also supplies Panasonic and Fujitsu, which provide a value mid-range option, and fi ll in some gaps in its off ering.

Since launching in 2002, air conditioning distributor Cool Designs Ltd has carved out a distinctive niche in the UK market.

SKILLS LEADERSHIPTraining is a priority for CDL, and it now operates three fully-equipped training centres around the country. With a combined capacity of 30 places, it aims to train some 200 engineers each year – making it one of the leading providers among distributors.

Its growing online library of

training videos off ers a 24/7 resource for engineers, that over time is building into a valuable industry resource.

While splits and VRF systems account for the bulk of sales, CDL also off ers chilled water solutions, with access to Carrier chillers, fan coils and air handling units.

“Air conditioning is a good

business to be in,” says Darrel. “We are optimistic about the future and the prospects for continued growth. Our business is built on strong relationships, with both customers and suppliers, and a willingness to go the extra mile. We believe excellent products supported with great service is a winning formula.”

OUT AND ABOUT42 OUT AND ABOUT


Out and About with Will HawkinsTQ EnvironmentalThis month, Will Hawkins, went to see Jenny Boucher and Gary Hall at TQ Environmental, the leak detection experts in Wakefield, to learn about their history and their future.

TQ Environmental

has been in business for 25 years designing, creating and installing its gas leak detection

system into ships, hotels, factories or retails stores. Anywhere, in fact, that uses systems containing refrigerants or other gases that could cause harm to humans or equipment if they leak and it went undetected.

The business started out selling other company’s products mainly into the marine sector. When customers starting asking them for solutions which didn’t exist but were in demand, they started making their own products. The shipping sector tends to order fi ve years ahead in US dollars which

made for interesting challenges dealing with currency exchange changes. Furthermore, relying on the shipping industry entirely made the business vulnerable to downturns in the sector.

DIVERSIFICATIONUnderstandably, TQ Environmental decided to diversify their business into land-based markets to ensure their business could survive. Niches included refrigerants, such as leak detection for applications using ammonia.

Retail refrigeration is an important sector for the business which includes leak detection for Morrisons across the UK. TQ has trials happening in other UK supermarkets too.

TQ Environmental has grown in spite of the recent recession, in part due to their work with some of the large supermarkets who installed leak detection into their stores.

The hotel industry is another sector where Gary and Jenny are developing their business. Leak detection is an increasingly interesting sector where customers want to look after their guests’ safety. Detecting refrigerant leaks from the air conditioning systems gives hotel owners peace of mind that they are providing the best environment they can.

But, hotel rooms have particular challenges with refrigerants. Many deodorants, for example, use R410A as the propellant and so TQ puts leak detection systems under beds to avoid false alarms.

SERVICINGTQ’s skills and experience are so developed that the business is now servicing their competitors’ leak detection equipment too.

Given the amount of servicing they do for customers as part of their contracts, Jenny and Gary hired a technical expert to manage their service business. As a result, their service business doubled and they hired another service manager to handle the amount of business.

The company looks and feels set to continue its success. TQ is part of a ‘Growth Accelerator Scheme’ to help Jenny and Gary move the business forward. And, they are hiring apprentices too to help them pass the skills and experience on from their loyal employees to the next generation of leak detection experts.

TQ Environmental has a strong pedigree in its fi eld. Despite their low key, unassuming nature, Jenny and Gary have forcefully changed the business to secure its future by being laser focused on their strengths and how they can help their customers.

43CONTROLS


A prestigious and modern North London property is now benefiting from Wi-Fi controllable air conditioning that links to a state-of-the-art automated home system to provide cost effective and energy efficient comfort all year round.

Orbital Climate Solutions, who install bespoke air

conditioning and ventilation systems across London and the South, worked closely with the home automation specialists IntelliCasa, to deliver a fi rst-class climate control system that provides discrete comfort for the homeowner whilst matching the high end refurbishment of the 5-bedroom home.

Award winning IntelliCasa specialises in home automation systems for discerning private clients and has a mission to allow customers to take advantage of the most cutting edge technology today.

“It was essential that we delivered an air conditioning system that was compatible with the sophisticated automation system IntelliCasa were installing”, explained Brett Strivens, Managing Director at Orbital.

“We listened to what the client wanted and our design team looked at all the diff erent manufacturers to fi nd the best solution.

“The M Series from Mitsubishi Electric proved perfect because it would deliver the right climate to the environment and off ered the option of the MELCloud Wi-Fi controller which we were able to integrate into the Intellicasa control system”.

Comfort underControl

Orbital installed the M Series outdoor unit on the roof and used ducted indoor units behind discrete plastered-in grills to deliver air conditioning to the property.

The Orbital team had to stick closely to the overall refurbishment schedule, whilst working closely around the other construction specialists on site as the refurbishment of the home was taking place.

A close relationship with both the IntelliCasa team and controls specialists at Mitsubishi Electric helped ensure that the integration

of the air conditioning into the home automation system went smoothly.

“The homeowner was looking for fi rst class climate control without aff ecting the aesthetic look of the high end fi nish throughout the property and the fact that we were able to use MELCloud to make the air conditioning work seamlessly with the rest of the high tech equipment really made the diff erence”, explained Brett Strivens.

MANIFOLDS44


ENGINEERS, IS IT TIME FOR A MANIFOLD UPGRADE?Things are slowing down slightly and the planned maintenances are now taking up the time of many engineers up and down the country.

Leaving fridges and cellar coolers on defrost is common place, so what to do with all this spare time on your hands. Obviously the café is the best idea but a good van clean out and tools check over can be very benefi cial!

Manifolds are the most common used item on an engineer’s kit and let’s be honest we want these to be in top condition due to the pressures they have to deal with. Any manifold which is looking a bit aged and has seen a good life and fell off the top of a fridge a few times should really be upgraded.

WILL MY CURRENT MANIFOLD SUIT R32? NO!!!!We will see a new range of manifolds available in 2016 to keep up with the ever increasing refrigerant ranges. One of the biggest on everyone’s lips will be is what changes will be happening to manifolds when the mildly fl ammable R32 gas is common place.

For the REFCO range from JAVAC our manifolds will see changes to the scales to suit R32 and R410a. All manifolds will be dual scale with R32 and R410a on the HP and LP gauges. The body of the manifold itself will be available with and without a sight glass and as always we will have this available in two valve and 4 valve in a case with hoses.

All R32 A/C equipment will have fi ttings of 5/16th male fl are. This is the current standard for R410a systems. This been the case means that all R32 manifolds will have hoses with 5/16th connections on one end which will fi t all systems for R32 and R410a. The 3 hoses will consist of a Blue Red and Yellow hose.

The yellow hose will also remain the same and have ¼ x ¼ connections to fi t bottles, vacuum pumps and recovery units.

CAN I USE MY R32/R410A MANIFOLD TO NITROGEN PRESSURE TEST? NO!!!You wouldn’t believe how often we hear excuses from engineers about why they used a standard refrigerant manifold to nitrogen pressure test. We have written numerous articles on the

reasons why standard refrigerant manifolds should not be used for pressure testing.

The main reason is that sight glasses can rupture under excessive nitrogen pressure.

The reason they can rupture is that manifolds have rubber seals, rubber seals need to be lubricated to work effi ciently. Nitrogen blasted through a manifold will dry these seals out, dry seals will then split, crack and move thus exposing the valves and sight glasses to 40+ bar of nitrogen! Not good!

USE THE RIGHT PRESSURE TESTING MANIFOLDThere are now manifolds available which are specifi cally designed for nitrogen pressure testing.

The JAVAC PVR is specifi cally designed for this as it uses Tefl on style piston valves and also does not incorporate a sight glass.

44-45 Javac.indd 44 23/10/2015 09:31

45MANIFOLDS


The PVR also comes with stainless steel braided hoses rated to 250bar with adaptors for R410a systems. This also eliminates the chances of over pressuring the manifold to almost zero.

WILL DIGITAL MANIFOLDS INCORPORATE THE NEW GASES? YES!Some Digital manifolds for 2016 will now incorporate the new fl ammable refrigerants this includes R32, R600, R290, R1234YF, R1234ZE plus other non-fl ammable new refrigerants. Basically if the refrigerant is on the manifold database then the manifold and its hoses are completely safe to use. Subcritical CO2 is also now a standard refrigerant on digital manifolds. Please be aware that Transcritical will not be featured on any digital manifolds unless otherwise stated. This is due to the operating pressures in excess of 100 bar.

WHAT HOSES CAN I USE FOR THE NEW MILDLY FLAMMABLE REFRIGERANTS?Refco manifolds for the new mil dly fl ammable refrigerants including R32 will be supplied with standard refrigeration hoses, the only diff erence been that the hoses will have 5/16th connections on one end.

Hoses are now also designed to fi t into tight areas when the hose has a ball valve fi tted. These hoses are standard hoses 36”, 60” or 72” long. On one end there will be a ball

valve, this ball valve will however be located 6” back from the end of the hose connections.

This off ers the user better access into valves on A/C systems where space is an issue. Hoses with standard ball valves directly on the end of the hose can sometimes be tight when connecting to the valve. Where possible I would also use ball valves as extra safety from refrigerant burn on hands even though apparently every engineer wears Gloves!!!!!

fl at rood for example, the wind loading will be greater.

The use of a Pump House Flexi Frame is a good way to prevent your condensers from blowing and succumbing to wind loadings. They are designed to withstand typical UK wind speeds by off ering a large, stable framework base, however we would always recommend checking with a consultant or ourselves if you are unsure on the feasibility of using a framework.

TF Solutions are the only accredited Flexi Frame Distributor, if you would like any more information on the range please contact us.

This month, we’re looking at frameworks and how you

can stay safe on the job.

Q: I am looking to support condensers on a roof top and have been advised to try and make up my own framework with feet and slotted channel, would this work?A: As a distributor, we are approached frequently by engineers who are looking to create their own bespoke framework. Engineers are completely entitled to design their own frameworks on sites in this way, but as a distributor we would strongly advise against this for health and safety reasons. In 2013, we became the only Flexi Frame Accredited Distributor with Pump House and we believe that using frameworks such as theirs is the safest and most effi cient way to support condensers on a rooftop.

When you are supporting thousands of pounds worth of equipment on site, we would always recommend using a product that has had years of research and development put into it. There are various elements you have to take into account when mounting equipment on a rooftop such as wind, roof shape and weight of equipment. Using an approved and accredited framework is certainly the safest way to ensure your equipment is mounted correctly.

Q: How do I ensure the condenser is level on a typical fl at roof?A: It is vital to ensure that your condensing units are installed level and securely. Creating your own framework with standard feet is okay however you cannot ensure it is level if the roof surface is not. One of the best ways to get around this is to use a Pump House Flexi Frame. The Flexi Frameworks come complete with adjustable feet so you can ensure your condensers are level on rooftops.

The Frames are available as two main components Base Frames and Extender Frames, and these can be structured and bolted on to suit any size and quantity of condenser.

HEAT RECOVERY48


That was the case when I visited Keelham Farm

Shop on the outskirts of Skipton, Yorkshire. David Haughton and Ken Riley from DK Heat Recovery invited me up to see how they are helping this outstanding farm shop use heat recovery from its refrigeration systems to generate hot water and heating to save hundreds of pounds a month off their energy bill.

Keelham Farm Shop is a privately-owned business with two shops in its group. The owners supply the shops from their own farm and 400 other local farms. The Skipton shop is an impressive building which includes the shop, a cafe and restaurant, bakery, flower shop, butchers and an ale house. It opened in June 2015 and its owners were keen to ensure that it was environmentally friendly and efficient.

It is a busy place with shoppers and visitors to the cafe. The shops has a range of retail refrigeration pack systems for the fresh produce, which Franchill installed and commissioned. The shop needs not only refrigerated produce but also hot water for the kitchen, butchery and wash rooms. In addition, the offi ces need heat to keep them comfortable.

THE HEAT RECOVERY SYSTEMHeat from the refrigeration systems is recovered using three DK Heat Recovery heat exchangers

in a 750 litre storage tank provides 24kW of heat recovery. DK’s system can provide over 500 litres of hot water per hour. For the heating system, there is a 300 litre buff er tank which includes a 12kW heat exchanger.

Ken Riley explained that the DK heat exchangers have a patented design which separates the refrigerant from the water. This means it meets the EN1717 legislation, which is required for businesses handling food.

The heat exchanger’s simple design is eff ective. It can remove up to 100% of the heat produced by the refrigeration plant. However, at the Keelham Farm Shop, David said they use only about a quarter of the heat available. The team at Franchill were keen not to ‘over-condense’ the system and aff ect the compressors. The heat recovery system was designed to avoid that and be the slave to the refrigeration plant.

When is the last time you went into a farm shop and thought ‘This is amazing’?

How A Yorkshire Farm Shop Uses Refrigeration to Supply Hot Water

By Will Hawkins - Editor

49HEAT RECOVERY


HOW QUICKLY WILL IT PAYBACK?To keep track of costs, the owners asked for a heat meter to be fitted so they could keep an eye of the amount of hot water being used. Since installing the heat recovery system, the farm shop has saved around £500 per month on its energy bills.

Heat recovery systems like this can pay for themselves quickly. Payback for hot water systems is usually between two and three years, according to Ken. The best results they achieved on a heat recovery system was 171 days. Payback for heating systems is usually between five and six years. It takes longer because it is not used all year round.

The Keelham Farm Shop system for hot water will pay for itself within two years. In its first four weeks of trading, the DK heat recovery system saved 4,700 kWh and provided 140,000 litres of hot water. And, its carbon footprint has dropped by 25 tonnes a year.

WHY IS HEAT RECOVERY NOT MORE WIDELY USED?Heat recovery is popular with food retailing businesses. They usually need lots of hot water water and they have a heavy refrigeration demand. Heat recovery in Europe is used more widely than in the UK. That’s partly because fossil fuel prices have plummeted recently because of the amount of shale gas available on the market.

Also, the UK government focuses on subsidies for renewable power generation and renewable heat. There is no focus on heat recovery or energy reduction, which is puzzling, at best.

On top of that, most food businesses, especially supermarkets, do not want to spend their capital budgets on energy saving equipment which does not provide returns now. Why? Because they are always short on capital budget, which means they prefer to invest in projects which increase their production.

However, with heat recovery, as mentioned above, paybacks can be surprisingly quick. And, businesses can pay for their energy once and use all of it or most of it twice. Installers who understand the principles of heat recovery, and that they can help their customers get free hot water, stand to do well out of the technology.

It is relatively simple to connect to existing refrigeration kit. The equipment can be installed in winter in the refrigeration and air conditioning ‘off-season’, providing additional business. And, the margins are pretty good too, apparently.

BENEFITS WITHOUT THE RED TAPEKeelham Farm Shop is benefiting well from heat recovery. There’s no RHI subsidy for this installation, but it does not matter. This Yorkshire business is driving costs out of its business and providing great value to its customers (A huge punnet of English strawberries was only £2, for instance).

With some clever DK Heat Recovery kit, the owners are not making use of the heat from the cooling to keep their customers comfortable while the produce stays fresh. It is the laws of physics at work without having to fill out the paperwork associated with the Renewable Heat Initiative.

That’s smart thinking of the freshest kind.

LEGIONELLA50


If there’s one thing you can be sure of with regard to your

customers, it’s that they know how to use Google.

Just as doctors meet plenty of people who have convinced themselves they have cancer, and most car salespeople have dealt with the buyer demanding they match a deal he found online, an ACR contractor now must be ready to reassure the smartphone-wielding customer that a system is safe from whatever faults he or she may have read about.

With air conditioners, the Google problem is Legionnaires’ disease. Enter a search like ‘air conditioners legionnaires’ or ‘air conditioners legionella’ and you’ll see no shortage of words on the subject.

If you’ve seen these, it’s a fair bet your customers have. Here are some of the questions you can expect to get asked, and how best to respond.

“I’VE READ THAT AIR CONDITIONERS CAN CAUSE LEGIONNAIRES’ DISEASE, IS THAT TRUE?”Short answer: no. Legionnaires’ disease is caused by the Legionella bacteria, which multiply and spread in contaminated water. When this water disseminates into the air as droplets and is then inhaled, it can cause the disease. However, as conventional air conditioners do not have water inside their systems, they are not likely to be

the source of the bacteria.The worst an air conditioner

will do is disseminate already-contaminated air throughout a building, which is only an issue with systems designed for larger buildings such as offi ces. It is a myth that air conditioners in any way “cause” Legionnaires’ disease.

“SO HOW DO I MAKE SURE I DON’T GET THE DISEASE?”First, remember that Legionnaires’ disease is rare. It can’t transfer from person to person, and it’s perfectly possible for someone to be exposed to the bacteria without actually catching the disease.

With that said, there are plenty of sensible cautionary measures that can be taken in order to minimise the risk of the Legionella bacteria spreading through a building. The most important thing is to look at the water system – is the water being stored at temperatures between 20 and 45 degrees centigrade (optimum Legionella breeding conditions)? Is it routinely circulated? Is it rusty, or sludgy, or fi lled with organic matter and mould? These are all things that can allow the bacteria to multiply.

It’s important to remind customers that any new system is very unlikely to have any bacteria inside it, and therefore a new air conditioner won’t make them ill. What allows disease to spread is a badly maintained system with rust and dirt building

up inside it. There is no substitute for rigorous regular maintenance and the implementation of sensible precautions. In the case of a domestic water system, making sure the water is regularly heated to above 60 degrees centigrade is an excellent start.

“HOW WOULD I KNOW IF I DID GET IT?”The symptoms, though somewhat fl u-like, are quite specifi c. Most commonly a suff erer will experience fever, chest pains and a cough, and also might encounter achy muscles, headaches, tiredness, a confused mental state, chest pains and shortness of breath. Advise customers to book in with a GP if a combination of these symptoms starts rearing its head.

It’s a complex topic, and you never know what a customer might ask next, but if you stick to these key points then you should be able to reassure even the most avid Googler that their air conditioner poses no risk.

ABOUT THE AUTHORTony Ellerker has worked in the building services and construction industry for over twenty years. He is currently the director of Blakes M&E Building Services, who provide pre-planned maintenance, reactive repairs and in stallations of all mechanical and electrical systems throughout London and the South East.

DAIKIN UK’S ALTHERMA FLEX TYPE QUALIFIES FOR NON DOMESTIC RENEWABLE HEAT INCENTIVEDaikin UK’s air-to-water heat pump, Altherma Flex Type, has become one of the first in the UK to qualify for the UK’s non-domestic renewable heat incentive (ndRHI). The innovative large-scale heat pump system installed in the headquarters of Barkwell Plumbing and Heating in Okehampton, Devon, will receive the financial incentive in the form of quarterly payments over a 20-year period.

The UK’s non-domestic RHI was fi rst introduced in November 2011 and later amended to include

additional technologies such as air source heat pumps in May 2014. The incentive aims to encourage industrial, business and public sector organisations to generate and use renewable heat within their buildings.

In order to qualify for the incentive, the design Seasonal Performance Factor (SPF) of the Altherma Flex Type system installed at Barkwells had to be calculated. This was estimated to be 3.0, exceeding the minimum requirement of 2.5. As per ndRHI guidelines, heat and electric meters were fi tted to measure the amount of energy generated and consumed.

The Altherma Flex type system is able to produce water temperatures up to 80°C and is suitable for a wide range of applications from schools to hospitals and offi ces. Systems can be cascaded together to supply buildings with large heat demands of several hundred kilowatts.

Robert Barkwell, who heads the family business BJ Barkwell & Sons, says, “We were very interested in installing a renewable

solution that would provide an opportunity to apply for RHI funding, and we felt Daikin off ered the best solution.

“Mains gas was in place but we wanted to demonstrate that there is an alternative. We wanted to prove that renewable technology will only benefi t our business in the long term.”

Stuart Gadsden, Renewables and Heating Product Manager said: “We hope this will encourage new and current users of the technology to take advantage of the scheme which is currently rewarding renewable heat producers by paying them for the amount of heat they generate.”

Become a Master in Renewable EnergyThe European Energy Centre is helping individuals enter the renewable energy market with the launch of a new certification, the Renewable Energy Award.

The training programme includes modules in fi nance, heat pumps, solar thermal, solar PV,

biomass and CHP, to name a few. Students have to pass a minimum of nine modules out the 12 available

in the programme to gain the qualifi cation.

Demand for the course, according to the Centre, strong because students want to diff erentiate themselves in a quickly developing and competitive market. Delegates for the courses so far includes people from 105 countries.

Training is delivered remotely and fl exibly using videos, webinars and other study materials. Many learners fi t the training in around their working lives in the evenings and at weekends.Users can use laptops, tablet PCs or smartphones to see the training. Learners have to complete nine modules within 18 months of starting to get their certifi cates.

It is not all remote learning, however. Students can attend some of the modules at participating universities. When students pass three quarters of the modules, they are automatically entered into the EnergyCPD Professional Membership Programme’s top membership level.

At nearly £3,000, it is probably a course which many will need help in funding to complete it. However, it is possible to pay in installments and the price is now subsidised.

GROUND SOURCE HEAT PUMPS54


Burton based Trent & Dove Housing has been

working in partnership with British ground source heat pump manufacturer, Kensa Heat Pumps, to install ground source heat pumps (GSHP) to nearly 200 rural sheltered properties scattered across East Staff ordshire.

At a visit to a home in Burton upon Trent which has recently undergone a GSHP installation under the second phase of the project, Lord Bourne expressed his admiration for the scheme, made possible largely due to the

innovative way it accesses streams of government funding. He said:

“Social housing tenants in East Staff ordshire are saving hundreds of pounds on their energy bills thanks to Trent & Dove’s innovative project, in partnership with Kensa.

“It’s great to see Trent & Dove putting the consumer at the heart of their plans, leading the way for others to follow.”

MICRO HEAT NETWORKThe system approach utilised by this scheme is recognised by DECC and Ofgem as a ‘micro heat network’ and qualifi ed the project

for Energy Company Obligation (ECO) funding, and 20 years of income via the Non-Domestic Renewable Heat Incentive (RHI).

Steve Grocock, Director of Property Service at Trent & Dove Housing is eager to promote the benefi ts for all involved:

“Over the last two years, we have been working hard to help our tenants reduce their fuel bills by installing sustainable energy solution such as external wall insulation.

“Tenants involved in the fi rst phase of this GSHP scheme are already seeing energy bills reduced by as much as 50%,

An award winning housing association project to help tenants save money on energy bills continues to garner praise; this time from Lord Bourne of Aberystwyth, Parliamentary Under Secretary of State for the Department of Energy and Climate Change(DECC).

and, anecdotally, are reporting significant improvements to their health and well-being, aswell. We estimate that tenant electricity costs will be reduced by a total of over £50,000 per year, at an average of £390 per resident. The average electrical energy consumption of each property is expected to drop by 75%, producing an annual CO2 saving of 2.8 tonnes of carbon dioxide (tCO2).

“At the most local level, we are helping some of the most vulnerable people to stay warm, but the impact of the scheme is much greater still as the reduction in CO2 will benefit on a global scale.

“We are delighted that Lord Bourne has chosen to visit our project and we hope more housing associations use the ‘blueprint’ we have created, to access the funding necessary to install innovative heating systems such as GSHP’s and make a real difference to people’s lives”.

PHASE TWO EXPANSIONThe second phase of the ground source heat pumps retrofit works sees the district heating solution being introduced to a further 60 Trent & Dove Housing properties in Burton upon Trent.

During his visit, Lord Bourne, visited tenant’s homes to see for himself the impact the installation of a renewable heating solution has had on them.

Mr Bullock, a Trent & Dove Housing tenant, has lived in his flat for the past 9 years; it was previously heated by electric night storage heaters. His new heating system, powered by a GSHP was installed last week and he is already feeling the difference:

“My flat has never felt so warm,” said Mr Bullock.

Phase two of the GSHP installation project is due for completion in October 2015. The project is currently being documented via a live blog on Kensa’s website at www.kensaheatpumps.com/category/blog

Trent & Dove Housing and Kensa Heat Pumps have released a video documenting the first phase of the project, which saw the installation of ground source heat pumps into 133 bungalows. View the video at www.kensaheatpumps.com/video/case-study-trent-dove-housing

Finnish city uses waste heat from data centre for

district heating scheme

BITZER ECOLINE compressors

Currently, with a total capacity of four megawatts, the heat pumps supply about 1,500 homes with energy.

56-57 Blitzer.indd 56 23/10/2015 09:19

57HEAT PUMPS

Here is how the project works and how it benefi ts the city.

USING WASTE HEATThe aim of the project is to effi ciently exploit the waste heat from a computing centre for district heating and to protect the environment. Heat exchangers fi rst use the hot air extracted from the computing centre to heat water.

In the next step, heat pumps in a district heating facility then raise the temperature of the water from 40 to 85°C. In this way, 75% of the energy originally used can be reused. This is not just very effi cient, it also protects the environment.

In the fi rst phase, the CO2 emissions will be reduced by 4,000 metric tons per year and, when the project has been completed, this will


be up to 11,000 metric tons of CO2 every year. Calefa’s role in this is to enable the entire technical conversion of waste heat into useful heat.

One special feature is that this is the fi rst time when such a large amount of waste heat from a computing centre can be directly exploited for district heating. To increase the water temperature to 85°C, particularly powerful and effi cient heat pumps are required. This process is supported by 24 six-cylinder ECOLINE compressors from BITZER at the heart of the heat pump system, which can each off er fl ow rates of up to 150 m3/h (at 50 Hz).

CONFIDENCE DUE TO PAST PERFORMANCECurrently, with a total capacity of four megawatts, the heat pumps supply about 1,500 homes with energy. Subsequently, this will rise to about 4,000 homes. Today, this system already complies with the environmental targets of 40% lower CO2 emissions specifi ed by the EU for 2030.

“We chose compressors from BITZER because they have stood for high quality, reliability and good performance for decades,” said Vesa Tamminen, CEO of Calefa.

“That builds confi dence where the long service life of the compressors is absolutely vital for us. We also know from experience that we can work together well with BITZER and can rely on their service. Our team have been successfully using BITZER compressors since 2007.”

ON SCHEDULEThe tight schedule was a real challenge. Work began in June 2014 and the system to recover the waste heat had to be completely installed by December. This worked out due to the excellent cooperation between the operator of the computing centre (Yandex Finland), the district heating company (Mäntsälä Sähkö Oy) and the contractor (Calefa Oy).

Work has progressed well and the entire system will go into operation in October of this year. The heat recovery unit in the computing centre is already operational and can be connected to the heat pump system. The installation of the heat pumps started as soon as the building was fi nished in the middle of June. The work on the pipework began in June.

Bitzer’s customer Calefa recently won the Heat Pump City of the Year prize for it project that takes waste heat from a data centre and transfers it into a local district heating scheme.

The project exploits the waste heat from a computing centre for district heating and to protect the environment.

GROUND SOURCE HEAT PUMPS58


The ground source heat pumps, made by Finnish

company Lämpöässä, generate between 3 and 4 kW of heat for each kW of electricity that they use. This means the heat they produce costs nearly a third less than with fossil fuels. More typically, the Finnish-made heat pumps have a CoP (Coeffi cient of Performance) of 4. The new Esi and Emi models have a CoP of 4.56.

“These latest systems will continue to provide all of our customers’ heating and hot water, irrespective of weather conditions, but now deliver even greater savings and fl exibility on installation with easier control of operation,” said Finn Geotherm’s commercial director, Guy Ransom.

HE CONTINUED:“We have installed nearly 500 heat pump systems at everything from bungalows to large businesses such as the Longlands Business Park on the Holkham Estate in Norfolk. We’ve also been able to provide ground source systems to provide all of the heating and hot water for large stately homes, dispelling the myth that the technology is only applicable for new, well insulated houses.”

The monovalent heat pumps produce heat and hot water for domestic and commercial buildings. They are compact, which makes it easier to fi t them into tight spaces. Importantly, they are eligible for the RHI.

As with many of the leading heat pumps available today, the Finnish heat pumps can be controlled through the internet using smartphones, computers or tablet PCs.

Easier, more adaptable solderingSwedish tools maker, Sievert AB, has a new range of Turbojet Swivel Torches to make soldering easier for engineers.

They are 50% lighter than the previous models and the new burners can swivel making them more fl exible for users. The rotating cyclone fl ame wraps itself around the pipe, providing extremely even heat distribution. Together with a built-in pressure regulator, the new Turbojet is suitable for brazing and soldering.

The new Turbojet comes in two models; standard, with a single cyclone burner and Turbojet Twin, with a twin burner. Both are fi tted with swivel fastenings, enabling rotation of the burner through 360 degrees. Turbojet twin has an extra swivel point, enabling rotation of the fl ame to fi t the work-piece.

Rittal Launches Innovative Blue e+ Cooling System in the UKRittal, the leading global enclosure and climate controls specialists, recently launched its new generation of cooling units.Key to the e� ciency of the Blue e+ is Rittal’s patented hybrid system.

“The hybrid system increases energy e� ciency signifi cantly,” says Ste� en Wagner, Rittal’s Head of Climate Control Product Management.

“It uses a clever combination of a compressor cooling device and a heat pipe to take maximum advantage of passive cooling. The compressor only kicks in when passive cooling becomes insu� cient to meet demand,” he adds.

Blue e+ units are six times more e� cient than conventional cooling units at a part-load of 15 per cent in heat-pipe mode. At a part-load of65 per cent, in hybrid mode, with both the compressor cooling device and heat pipe in operation, Blue e+ is four times more e� cient than a conventional unit.

Howard Davis - Stories from the FieldWith Howard Davis retiring from Frascold recently, Will Hawkins gathered some stories from the field which typify the humour and character of the man. Howard may be retiring, but we thought it would be good to say farewell in the best way we know - by embarrassing him with some anecdotes.

The stories include an unexpected trip back from Italy with John Smith of Dean & Wood when a volcano in Iceland pumped more greenhouse

gases into the atmosphere than all the old air conditioning units leaking R22 into the atmosphere.

The other story, thanks to Steve Taliadoros from LU-VE, involves Howard nearly laughing his head off when hearing that someone’s legitimate job involved helping pigs to relieve themselves for the benefit of reproduction. Sound dodgy? You are right there.

Read these stories on the ACR Journal website by visiting this link: http://w2u.eu/HowardDavis

(We’d like to publish them here but space is tight and we’d like you to leave your comments on the website!)

Pump House Fishing Day reels ’em inThe inaugural Southern Fishing Day from pumps and ancillary equipment supplier Pump House, and sponsored by Fujitsu, proved a great success, despite a certain lack of fi sh.

Helped by glorious weather, the event, for wholesalers and contractors, was held at Bury Hill Fisheries near Dorking, with the top prize going to Ben Mcgrath of BM Air Conditioning, with a catch of 20lb. The smallest catch prize of a bottle of bubbly went to Phil West, with a catch of just 11oz.

While Pump House has run several very successful annual fi shing days, they are normally in the North or Midlands, this is the fi rst time the Nottinghamshire based company has run an additional one in the south of England.

Says Pump House’s June Richardson, sales manager: “Everyone thoroughly enjoyed themselves and were already asking when the next fi shing day will be so they could put it in the diary for next year.”

The Southern Fishing Day will be an annual event, so send your details to [email protected] if you are interested.

Sun Comes Out for B&ES North West Annual Golf DayThe Building and Engineering Services Association North West Region held its annual golf day late in September at the Pikefold Golf Club, Bury, Lancashire.

The event was attended by representatives of Absolute Cool Heat, BSS Pipeline and Heating Solutions, Crown House Technologies, Ductwork Design and Installations, Arthur J Gallagher, Salford College and Vital Human Resources.

A total of 35 players from both member and sponsor organisations experienced an enjoyable day’s golf in excellent weather conditions.

The winning team was entered by Liverpool-based contractor Absolute Cool Heat Ltd.

Big Foot Pedals it to ParisSussex-based Big Foot Systems, the rooftop support for heating and cooling units specialists, took part in an ‘epic’ charity cycle ride from Eastbourne Pier to Paris and back in a weekend, recently.

The 255 mile bike ride raised in excess of £4000, including sponsorship from Big Foot’s Belgium distributor Linum. In total twelve people took part in the ride, including Big Foot’s Technical Marketing Manager, Joe Rose and Miles Hardy the fi rm’s Commercial Support Coordinator with the money raised going to Macmillan, Parkinson’s UK and Sussex Air Ambulance.

Along the way they battled through torrential downpours, a couple of pile ups, Parisian traffi c chaos and more than their fair share of punctures, but eventually they made it back to Eastbourne in one piece!

In the October issue, as the ACR Journal team and partners travelled around the UK to get stories and features that make this

magazine so popular, Paul Airey from Fujitsu spotted a Cool Breeze van in Edinburgh. The prize was claimed by Engineer James Young

from the company.This month’s photo was taken on 11th September on the M5 in

Devon by Will Hawkins. If this is your van, drop me an email with the van’s registration number, which I alone know.E: [email protected] to claim your prize.

“The bike ride was fantastic and it’s always nice to combine a fun event with raising some money for some really great charities,” explains Joe Rose, Technical Marketing Manager at Big Foot Systems. “We’d also like to thank our Belgium distributor Linum Europe for their generous support of the event.”

Williams’ ‘Cool Riders’ contest Springboard Paris ChallengeThere was more than one cooling industry company on two wheels, recently. Williams Refrigeration put a team into the Springboard London to Paris Cycle Challenge in September. The so-called ‘Cool riders’ team was a “mixed bag” of pedal pushers from across the food service industry, according to Williams Refrigeration sales and marketing director, Malcolm Harling.

Malcolm himself represented the catering equipment manufacturing sector; for the kitchen contracting houses there was Julian Shine, managing director of Shine Food Machinery; Stuart Timms, project director at Tricon, was in the saddle for food service consultants; and Mark Froydenlund, head chef at Marcus, held the torch for operators.

They raised money for the food service industry’s charity, Springboard (www.springboard.uk.net). The photo shows the team before they set off on the cycling challenge.
