WHAT ECO-PARK® IS ALL ABOUT

Eco-Park® is not one single thing. Rather, it is theoptimisation of all of the elements that make up aconventional car park ventilation scheme. Through acombination of the latest fan design, the most advancedcomponents and the most innovative control systems, we can deliver more sustainable, cost-effective car parksthan ever before.

It wouldn’t be an exaggeration to say that over the pasttwenty years virtually every new car park ventilationproduct, technique and system advance has come from theHC Group. And now, with Eco-Park®, we have gone one stepfurther, pushing back technical boundaries and enhancingbest practice to provide ventilation systems that offer aunique combination of long-term sustainability andminimum front-end costs.

We then superseded these withINDUCTION SYSTEMS

TECHNICAL SUPPORT

We then took innovation even further with thedevelopment of our patented, second generationinduction fan featuring aUNIQUE TWIN NOZZLE

Today the HC PVE twindischarge fan has rendered allother car park ventilationsystems obsolete. It is at theheart of HC PVE’s Eco-Park®.

We were the first to createTHRUST SYSTEMS

Our Eco-Park® Systems have been designed to deliveroptimum performance and efficiency whilst makingsignificant savings in a whole range of ways. They usefewer fans, require less cabling, rely on smaller controlsystems, use significantly less energy and save oncontainment. At the same time they reduce installationcosts, running costs, maintenance costs and whereverpossible raw material costs.

Moreover, because of our induction fan design, new-buildexcavation costs can be reduced drastically. Fans can alsobe fitted directly above driving lanes for better air qualityand optimum volumetric performance.

Structured approach

Our highly structured, disciplined way of working ensuresthat the quality of our system design is never compromised.Our technical team is design-focused, innovative andresponsive. Our design, engineering and modeling have ledthe way for many years and our collaborative approach tofire engineering now provides greater protection for peopleand property.

Mechanical and electrical component integrity

We exercise complete control over all of the elements thatmake up our Eco-Park® Systems and only sourcecomponents that have been thoroughly tested, interfacewithout problems and have a proven track record forreliability. Over the years we have forged strong tradingpartnerships with leading component suppliers specialisingin corridor ventilation, staircase ventilation and other areasof above-ground smoke control. All of them havedemonstrated to us time and again that their products areof the very highest integrity.

For over twenty years our Group’s pioneeringthinking has produced technical innovation aftertechnical innovation, advancing every aspect of carpark ventilation.

It is these advances, culminating in the introductionof our patented twin discharge induction fan, thathave led us to take the bold step of making the oldaxial-type Impulse technology obsolete within our organisation.

‘Impulse’ was simply a generic term for thrustsystems. Whilst Impulse systems were themselves abreakthrough in their day, they did have numerousdisadvantages, which our twin discharge fanaddresses.

IMPULSE DRAWBACKS

> Impulse fans lack volumetric thrust> The physical size of axial fans makes mounting

above car lanes difficult> A typical system requires more fans, cabling

and containment> A typical system requires larger and more

expensive controls> Impulse fans offer poor air distribution in

comparison to induction> Impulse systems use more energy> With new build and multi-storey car parks,

Impulse systems require deeper excavation

We can still supply these fans as replacements but when making a formal proposal will always put forward the latest technology based on our Eco-Park® induction fans.

DELIVERING INNOVATION

> PARKING IN THE UK TODAY – AND THE LEADING ROLE BEING TAKEN BY HC PVE> UNIQUE TWIN NOZZLE FAN THAT DELIVERS EXCEPTIONAL RESULTS

In the UK there are over 27,000,000 personal vehicles andthe number is still growing. Add over 7,000,000 deliveryvans, taxis and trucks and you have the number of vehicleson the road every day.

More and more shopping centres, office buildings,government buildings, hospitals and apartment buildingsare being built incorporating underground parking facilitiesto reduce congestion and ensure safe, clean off-roadparking for all users.

NEN 2443 states two types of parking facilities (open andenclosed). In the case of enclosed carparks, mechanicalventilation systems have to be installed unless they areprovided with sufficient openings to facilitate a naturallyvented system ( see requirements detailed within UKApproved Documents B and F ). The type of ventilationsystem depends on the individual car park but designsshould always be complient with BS 7346-7.

In the past carparks would be vented through use of aducted system. However, the disadvantages of the ductsystem include:

> The requirement to compartmentalise> Dead non-ventilated corners> Lack of controlled smoke exhaust> High energy consumption> Loss of parking spaces because of large ducting

Through use of thrust ventilators in carparks, the systemover the last fifteen years has evolved further. The originalthrust fans were similar to conventional tunnel fans andwhen the correct design philosophy was applied many of thedisadvantages of ducted systems were no longer an issue.HC Group have steadily developed and enhanced the thrustprincipal and recently introduced the unique twin nozzleinduction fan, which has now become the market leader dueto its enhanced performance and efficiency.

Thrust ventilation allows the construction of enclosedcarparks with an open and safe environment withoutcompartments or dividing walls. The exhaust air is extractedusing the main shaft fans. The airflow is determined by thecurrent regulations for carpark ventilation systems (BS 7346-7 and approved documents B and F).

HC PVE recommends that the exhaust air be extractedvertically with a maximum velocity of 10 m/s – 5 metresabove street level. Should the carpark be a combined facility,the airflow should, if possible, be emitted from the roof.

In the case of fire, visibility of at least 30 metres should beguaranteed 45 minutes after the fire has started and this isoften examined and proved by use of CFD at the design

stage. If possible, the supply air should be arranged via aconstructed/builders work opening or via the entranceramp. Should this not be practicable, supply air will need tobe introduced via shaft fans.

The supply and exhaust airflow openings will be providedwith grids. In the event of a fire, it may be necessary toclose some of the supply and exhaust openings to letmaximum airflow pass over the seat of the fire. Theinduction thrust fans assist the air moving through theparking garage ensuring the correct flow direction and that blind/dead spots are eliminated. Thrust ventilators use the natural phenomenon, which accelerates a mass asa result of propulsion. This is the force we measure interms of Newtons.

PEOPLE AND PROPERTIES

USING ADVANCED TECHNOLOGIES TO

PROTECT

HC PVE SYSTEM OPERATION

It is important to realise that ultimately the total amount ofair that will be moved will be a multiple of the air goingthrough the fan. This is what we term the induced power andit varies dramatically with the type of fan. Induction fans,depending on design, induce up to 19 times the volume of airpassing through the fan. With the older impulse fans thismultiple is only 8 times.

The location of the thrust fans in the car park is extremlyimportant for the overal efficiency of the system. With manyolder systems efficiency was influenced by the coanda orskin friction effect, the entry and exit conditions of the fanand the need to position fans above parked vehicles due totheir physical size.

In practice fans were often fixed against the soffit near todown stand beams or at worst at the junction of the walland soffit. Therefore there was, despite discharge guidevanes, always a coanda effect at varying levels meaning thetheoretical thrust was rarely if ever available in the installedmode. Also an operational car park would have manyvehicles parked that would inevitably hinder the flowpattern. As a result performance between test and actualcould be drastically different.

The discharge pattern of the modern induction fan virtuallyremoves any concern about loss of performance due tocoanda effect. The fans are ultra slim in design, whichmeans that they can be fixed directly above the car lanewhere their volumetric efficiency will have maximum effect.This is one of the big advantages of the induction fan overthe impulse fan.

The CO/LPG levels and all smoke monitoring within thecarpark will be checked on a continual basis by a PLC or aswitchboard. This is the heart of the parking ventilationsystem. The thrust fans can be individually monitored andwill in normal operation fully dilute the air in each area ofthe carpark.

In the case of fire, the thrust fans will create a virtualsmoke corridor, enabling the removal of large volumes ofsmoke and heat. The is entirely in accordance with currentUK and European legislation.

Ventilation using thrust fans is demand driven, air flowthrough a carpark continually fluctuates in line with thelocal environmental conditions, therefore there will be lessaerodynamic loss and lower energy demand.

Should the environment change, either by way of a changein the air quality or by the detection of smoke, the detectionsystem will record the change and the PLC will reactaccordingly. Depending on the location and status of anychange in air condition, the computer will activate theventilation system in accordance with the programmedfunctionality diagram.

Possible operation conditions

(1) Continuous low rate ventilation(2) Low CO/LPG alarm - fans will temporarily be activated

at given intensity(3) High CO/LPG alarm - the air speed and the airflow

activity will be increased until the levels reduce(4) Fire/smoke ventilation - depending on the location of

the fire, smoke pollution will be inducted and removedto the exhaust shaft

In 2003 HCPS developed, patented (Patent 1018285 ) andintroduced the modern day induction fan. This totally newand unique generation of fans has been developed toprovide many technical advantages and financial benefits.

The HC Group second generation Induction fan is singularlyunique in design. Our R & D developed and patented our fandischarge incorporating a twin outlet. The design of this fanensures a consistent flow away from potential Coanda orskin friction effect. This patented design has beenindependently tested and ensures a better volumetricperformance and higher efficiency than any other existinginduction fan.

Making use of the patented outlet venturi, higher and moreefficient performance and ultra flat design ensure oursystems offer the Builder and Developer the followingessential advantages and sustainable benefits.

> Extremely low build in height (max 250mm to 325mm)saving up to 200 mm per floor of excavation over olderimpulse fans.

> The impulse effect is increased by up to 300% when usingthe induction principal .

> Number of fans required on a typical installation reducedby up to 65% (see flow pattern CFD opposite) Therefore itis not possible to replace like for like with older axialbased thrust fans.

> On average energy consumption is reduced by 50% > Huge reduction and financial saving in cable and

containment, therefore cost of installation is also reduced. > Influence of down stand beams can be neglected for

correct system operation.

> Fans mounted above the drive lanes therefore flow isunhindered ensuring maximum volumetric performanceat all times.

> Induction systems require smaller back up power supply. > Huge reduction in cost and time for maintenance

The benefits and advantage of car park ventilation systemsusing the new induction principal can readily be comparedto similar operations using older impulse fans such thatthese older products have now been made obsolete.Likewise the volumetric performance of induction fans canbe determined and compared by the following:

(A) Thrust in terms of Newton’s(B) Position efficiency(C) Induction power(D) Outlet operating without deflection blades

GENERATION OF FANS

A TOTALLY NEW AND

UNIQUE

Note to AThe new induction fan can be supplied in both 50 and 100Newton versions and shortly there will be a 40 Newton variant.

Note to BThe ultra slim silhouette of the fan allows each unit to bemounted above the driving lanes. Obstacles such ascolumns and parked cars that can block the airflow have aminimal effect allowing maximum induction of air into theflow pattern. This is not possible with fans installed close tothe wall or above parked vehicles.

Note to CMeasurements produced by independent consultants show that the induction fan can induce up to 19 times theair actually passing through the fan. This is substantiallymore than with any impulse or jet fan based on older axial technology.

Note to DThe internal fully patented venturi ensures that thedischarge of the HC induction fan does not need deflectionblades that often hinder airflow. Furthermore, this ensuresthere is a consistent velocity over any alarm sensor,preventing false alarms or activations.

The combination of the above makes it possible todrastically reduce the number of thrust fans, inevitablyleading to the many advantages outlined.

Together with the customer and/or fire services, a CFDcalculation can be made in advance.

Using a CFD (Computational Fluid Dynamics simulation) itis possible to gain an understanding of the airflow andvisually check both CO and smoke/heat control.

To carry out this simulation, a 3-D model of the carpark willbe set up. With the help of mathematical formulae thetechnical installation and control strategy will be processedwithin the model. The entrance of the carpark will bedesigned as real openings or closed areas. After the modelhas been equipped with matching physical parameters, thesimulation will start. Using the limited volume method, theflow and energy balance per period of time will be solved.

The simulation results can be analysed per period fordifferent quantities. The results will be presented in adetailed report in accordance with the analysis/descriptionand concept direction of the particular site. Suchsimulations should always be carried out by independentconsultants and can be used to support the design processand its relationship to actual design by making it possible totest the system via simulation at an early stage.

Presenting the results of CFD simulation often reassuresand improves communication between parties and enablesthem to alter the scheme or the design of the building tofine tune the ultimate system.

COLD SMOKE

The simplest test uses coldsmoke. A smoke machine will beset up at the most criticallocations and will pollute the areawith smoke for a pre-set time. The ventilation system will beactivated and evaluated to ensureit removes smoke within a settime. Using cold smoke will alsoidentify any blind spots within the system.

HOT SMOKE

Finally there is the hot smoke test. HC PS hascarried out this test successfully for the first time ina carpark in the Netherlands. The thermodynamicinfluences are fully visible but the test will not harmthe building as a clean alcohol fire is used.

SMALL FIRE TRAY

This test cannot evaluatethermodynamic influences butthese can be partly reproducedwhen cold smoke is combinedwith a small fire tray test.

REAL VEHICLE FIRE

The most reliable test wouldobviously be when using real cars.However, this test is ratherexpensive, dangerous and canpossible harm the building. Thethermodynamic influences arenonetheless fully present.

The results of a cold smoke testeven using a small pan fire to aidthe simulation can differdramatically when compared to areal vehicle fire.

It is possible to test the thrust ventilation system after installation in different ways.

Innovation is not a fashion word for HC Group. The uniqueinduction fan (patent 101 8285) proved it. This fan iscurrently manufactured and delivered in two versions (50and 100 Newtons) to suit various carpark sizes. As part ofHC Group’s commitment to on-going research anddevelopment, a second generation fan was designed with aunique twin nozzle creating even higher thrustdevelopment and an even slimmer design silhouette.

Designs have already been completed and plans put in handfor a third generation of induction fan - to be introducedshortly. Our induction fans are also available wall mounted(duck neck) and as 300 and 600 Newton variants for tunnel ventilation.

In order to precisely adjust the volumetric performance ofinduction fans and control the air velocity, HC PS hasdesigned a special frequency controller. This is temperaturerated and HC PS is market leader in respect of its range ofproducts. This innovation also extends to advice,engineering, testing and service.

In 2005 the HC Group pioneered a revolutionary type ofsmoke test, incorporating the use of hot smoke to bettersimulate a fire condition within our installations.

The smoke was heated to the equivalent of 2.5MW fireintensity. This new type of heat allowed our engineers tobetter prove our system design capabilities, equipmentperformance and improve the safety for attending fire services.

CERTIFICATES

HC Group was the first company to obtain certification ofthe new generation induction fans (IDF-HC-50 v2 and IDF-HC-100 v2) in accordance with the EC initial type of testingand the EC factory production control. This certification isprovided by Lloyd’s Register (notified body number 0038).

With this certification HC Group has shown that the qualityof the production process, the quality of the end product andassociated specifications are guaranteed. Also, it can beproved that the fans comply with the standard EN12101-3: 2002 Class F, test method CD3.

This means that the fans continue to function for a period ofnot less than one hour at a surrounding temperature of300°C. This level of certification goes a step further than theseparate CE and EN12101-3 certificates, which HC PSobtained on the first generation induction fans.
