AQUAFLAIR B.R.A. is the new range of UNIFLAIR chillers, created according to new, unique

flexibility criteria. Nine air-cooled models with hermetic scroll compressors, or semi-hermetic screw compressors, plus axial fans, with nominal cooling capacity from 300 to 750 kW, available in four series:

- cooling only - cooling only for high ambient temperatures - free-cooling - ultra-low noise free-cooling

Our commitment to respect the environmental regulations, a commitment typical of UNIFLAIR products, is fully adhered to in these new series too. The series were designed for standard operation with refrigerant R407C and R134a (on request, R22 as well).

As we were looking to base the AQUAFLAIR B.R.A. series on cutting-edge technology, this led us to include many features and details. The basic version already includes a unit with a fan speed regulator, and, as optional items, an electronic thermostatic valve, and the economiserkit, to maximise performance and minimise operating costs.

Everything is controlled by the UPC1m control system: two I/O boards connected to the mP20II user interface, for full control of the all the unit's parameters. There are more items to complete the hardware: a LAN card and a clock card, both standard items, and the serial RS485 adapter (optional) for connection to the Uniflair supervision system or to o Building Management System. The AQUAFLAIR B.R.A. series models are top-of-the range in terms of technological design criterion, and flexibility. You can always chose the configuration suitable for each application, by highly restricting the range of outlet water temperature, thanks to partial (6 step in the 6-Scroll compressors unit or 8 steps in the 2-screw compressor models) or continuous control of compressors (unit with screw compressors).

The refrigerators can be supplied in low-noise or ultra low-noise versions, recording noise emission values among the lowest in the category.

As these new units cover a very broad outside temperature range, thanks to the series for high external temperatures (up to 50°C) and to the low external temperature option (down to –20°C), they can be used in all ambient conditions.

A great deal of attention was addressed to installation as well: the units can be supplied with 1 or 2 on-board pumps. All this makes the AQUAFLAIR B.R.A.

series true plug-and-play machines.

MAIN FEATURES

Air-cooled water chillers AQUAFLAIRB.R.A are designed for outdoor installation in residential, commercial and technological applications. The chilled water produced can be sent to fan coils or other terminal units for climate control or the air conditioning of technological environments. It can also be used for industrial process cooling.

Thanks to the UPC1m microprocessor control the units can be connected in parallel on a single water circuit in order to increase the units cooling capacity when needed. With the UPC1m control, you can create a local area network linking the microprocessor control boards, obtaining solutions to satisfy all needs.

The new range of UNIFLAIR AQUAFLAIRB.R.A water chillers features state-of-the-art technology to give maximum reliability, safety, quietness of operation and respect for the environment.

RELIABILITY

Trouble-free operation of Uniflair chillers is ensured by rigorous production process controls under ISO 9001-certified quality procedures: Particularly: • Quality control of components; • Pressure testing of refrigerant and water circuits; • Testing of current absorption and IEC safety testing; • Calibration and testing of instruments and safety devices; • Final testing of unit under operating conditions.

EASE OF INSTALLATION AND MAINTENANCE

All models are fitted with a main switch to enable direct connection to the mains power supply without the need for an external switch; short-circuit protection fuses should be fitted however.

All units are assembled and fully tested in the factory, making installation simply a question of connection to the electrical power supply and water circuits.

An important feature of the design is the positioning of components to allow easy access for service and maintenance.

ACTIVE SAFETY

UNIFLAIR safety and control systems have a supervision and prevention function with:

• Automatic blocking of components in dangerous conditions; • Indication of function status; reading and continuous display of circulating fluid temperature; • Management of compressor start-ups to reduce excessive switching on and off; • Acoustic alarm signal in the case of refrigerant leakage (only for units equipped with electronic thermostatic valve); • Automatic unit rotation during pump break down (only with 2 pumps group option); • Compressor start timing to reduce total unit start-up current; • Indication of anomalous function conditions and / or alarms; • Compressor crankcase heater (standard on version with low temperature option and on units equipped with free-cooling system); • Anti-freeze protection to prevent freezing of the evaporator, and pump group.

Versione 01.1 del 07.05.2004 13

PASSIVE SAFETY

The essential functions of UNIFLAIR chillers are protected against anomalous function conditions and potential damage with: • High and low pressostats on the refrigerant circuit (HP with manual re-set); • Safety valve on the high and low pressure refrigerant line; • Protection of electrical motors installed on compressors; • Differential pressure

PERSONAL SAFETY

The design and cabling of all UNIFLAIR chillers conforms to IEC electro-technical norms. Electrical panels are equipped with: • general switch and door lock switch; • automatic magneto-thermal switches for fans and auxiliaries; • automatic magneto-thermal switches for Scroll compressors;. • fuses on screw compressors; • motor overload cut-out on pump group.

The evaporator / pumps housing can be protected by protective grilles.

Fans are equipped with an external protection panel on fan compartment; which conforms to applicable safety norms.

RESISTANCE TO THE ELEMENTS

Corrosion resistance is an essential feature of UNIFLAIR chillers. They are built to operate even under very severe environmental conditions.The self-standing framework is made in galvanised steel sheet, with panels painted with epoxy powder paints (RAL 7037 colour) conforming to standard ASTM B117. Furthermore, all external screws, nuts, etc are in stainless steel.

ENVIRONMENTALLY FRIENDLY

UNIFLAIR products have always been built with respect for the environment. UNIFLAIR has continued offering solutions at the forefront of technology aimed at reducing environmental impact also for the new series of the AQUAFLAIRB.R.A

range. These solutions cover many aspects as follows: use of ecological refrigerants R407C and R134a, elimination of non-recyclable materials, lower consumption of energy by using components with improved thermo-dynamic efficiency, adopting free-cooling systems and compressors (scroll and screw) with high energy performance, studying sophisticated circuitry for the finned heat-exchangers.

ENERGETIC EFFICIENCY

The new AQUAFLAIRB.R.A models are designed to obtain maximum performance levels on minimum energy absorption. This result was achieved by use of partial heat recovery in the units, deploying 6 compressors (machine with scroll compressors) or 8 compressors (units with screw compressor). On partial pressure loads in each refrigerating circuit, the thermal range in each exchanger drops. This

leads to an increase of evaporation temperature and a reduction of condensation temperature, thus obtaining a very high COP (Coefficient Of Performance) value. Furthermore, on request, the units can be equipped with continuous modulation of refrigerating power to

further improve the COP value.

MAIN COMPONENTS

FRAMEWORK

The framework is made in galvanised steel sheet, with panels painted with epoxy powder paints (RAL 7037 colour) conforming to standard ASTM B117. Furthermore, all external screws, nuts, etc are in stainless steel.

ELECTRIC PANEL

The panel is built to conform to directive 73/23/EEC and to its relevant standards. The panel has a master door-locking disconnecting switch and is housed in an appropriate compartment protected by a panel fastened with ¼ turn screws.

The maximum internal temperature of the electrical panel is controlled by a thermostat, and is maintained within the parameters which ensure that the panel is protected by ventilation of external air.

Furthermore, versions supplied with modulating condensation control (units with the low ambient temperature option or free-cooling system), include a system for controlling minimum infernal temperature of the electrical panel by means of a self-adjusting anti-condensate electrical resistor.

Main features:

• phase sequence relay • in IP44 protection class; • 24 V auxiliary circuit for mainboard and fan contactors; • 230 V auxiliary circuit for compressor contactors; • phase monitor to ensure correct screw rotation (screw compressors) • phase monitor to ensure correct screw rotation (screw compressors) • every compressor is protected against overload and short-circuit by an automatic thermo-magnetic circuit

breaker (units equipped with scroll compressor) • fuses protect each compressor against short-circuits (for unis with screw compressor) • fans protected against overload and short circuit by an automatic thermo-magnetic circuit breaker; • pumps protected against overloading and short-circuits by motor overload cut-out. • contactors provided for compressors and pumps; • 2 voltage-free contacts for remote signalling of addressable alarms.

COMPRESSORS

Compressor nr x mod 6 x Scroll 2 x Screw

Units equipped with SCROLL compressors

The new AQUAFLAIRB.R.A series is equipped (up to 400kW) with 6 ultra-reliable rotating SCROLL compressors connected in tandem.

All units have two independent cooling circuits, this assuring at least 50% capacity in the event of problems with one of the two circuits, as well as very good part-load performance in terms of energy consumption. This solution means routine and non-routine maintenance work can be carried out during unit operation by virtue of shutoff valves on the compressors (discharge). The control system also implements compressor rotation, ensuring that all four compressors work for the same number of hours.

Microprocessor control manages the switching on and off of the compressors in order to ensure effective control of unit capacity; capacity steps are:

0% 16% 32% 50% 66% 82% 100%

In order to prevent the refrigerant fluid diluting the oil and creating foam when the unit is started all free-cooling models are fitted with oil heaters which switch on automatically when the compressor stops. (Standard for Free- Cooling series, and with low external temperature option) To attenuate transmission of vibrations, and hence reduce noise levels and possible faults, each compressor is fitted on rubber mountings.

UNITS EQUIPPED WITH SCREW COMPRESSORS

Models with refrigerating capacity of over 400 kW are equipped with two screw compressors of the double screw compact type. These compressors are supplied by the market's leading manufacturers. They are supplied with: temperature sensor fitted in the over-current protection windings, a non-return valve on the delivery line both for preventing screw reverse rotation, and to allow equalisation of the pressure values inside the compressor for pressure free starting.

Both compressor have partial heat recovery in four steps (0 – 25 – 50 – 75 – 100%) and, therefore, the temperature of discharged water is controlled in 8 heat recovery steps.

0% 13% 25% 38% 50% 63% 75% 88% 100%

This ensures high COP values at part loads.

Versione 01.1 del 07.05.2004 19

Furthermore, the compressor can be supplied with a slide valve with built-in economiser. This ensures greater liquid supercooling. In addition, thanks to the modulating inlet midway along the screw, one can improve the compressor process, by eliminating the low pressure at which the compressor normally operates. This ensures that COP is increased also at underpressure values, since the increase in yield is much higher than the increase in absorbed power.

Furthermore, on request, the units can be supplied with continuous modulation of refrigerating power to further improve COP. In this way, the refrigerator absorbs only the energy required by the system at any time, thus considerably cutting down electrical consumption.

To attenuate transmission of vibrations, and hence reduce noise levels and possible faults, each compressor is fitted on rubber mountings.

Ever an environment-conscious company, UNIFLAIR has designed these units for use with HFC-R407C, an environmentally friendly refrigerant, though they can also work with R22 or R134a - apply to UNIFLAIR ITALIA S.p.A. with your request.

FANS

The units feature motor-driven sickle-blade axial fans, 800 mm in diameter. They are directly connected to external rotor motors which can be fitted with voltage modulation speed control. The metal support grille conforms to all the main safety standards. The motors have IP54 protection under EN 60529.

CONDERSES

New AQUAFLAIRB.R.A models, are air-cooled. The condenser consists of coils with turbolence type aluminium fins (pitch: 1.8 mm) and copper tubes internally scored for maximum exchange efficiency. The aluminium tube shoulders eliminate the risk of pipes breaking due to vibrations or thermal dilation.

The coil has a large surface area for operation even with high external temperatures.

In the series for high temperatures (BRAT), this area is further increased in order to reach ambient temperatures of about 50°C.

20 Versione 01.1 del 07.05.2004

If there are harsh conditions in the installation environment, various treatments are available for the exchanger: pre-painted aluminium, copper-copper protection and cataforesis aluminium treatment, which provides the best compromise between cost and performance (all on request).

EVAPORATOR

The shell & tube exchanger is removeable, has two cooling circuits and a single water circuit which operates with a very low pressure drop is builted with high-efficiency tubes, in order to guaranteed oil outflow.

It is completely covered in closed-cell expanded polyurethane to prevent the formation of condensation and reduce thermal dispersion.

Furthermore, this material is UV resistant.

ANTIVIBRATION FEET

To cut down vibrations, AQUAFLAIRB.R.A units can be supplied with antivibration supports.

Uniflair has selected spring supports for its units. They comprise five springs. These supports allow considerable yielding while being highly compact. As a result, they are particularly efficient in insulating low frequencies, typical of machines, such as refrigerators, running at low revs.

Moreover, the construction design permit to use in particularly difficult and/or aggressive places, as the supports are highly resistant to oils, corrosion and high temperatures.

Specifications: the springs are in C72 steel, and are epoxy painted; the bases are in elastomer with metal insert

HYDRONIC SECTION

The hydronic section of AQUAFLAIRB.R.A units is equipped with:

• Pump group: 1 or 1+1(stand-by); • Victaulic type connection to the user (only if pump group supplied); • Inlet interception valve (each for one pump) • Water flow pressure switch (standard) • Two interception valves on pump (inlet interception valve and non return valve on discharge, only

with pump group 1+1); • Exhaust on connection (standard with hydraulic kit); • Anti-freeze on (options):

-Evaporator; -Connection pipes; -Pump group.

A GUIDE TO THE SIZING OF THE EXPANSION TANK

The project elements to consider when selecting the dimensions of the buffer tank for a system are: C The quantity of water in the system in litres;

e the expansion coefficient of the water, calculated as the maximum temperature difference between when the system is off and when the system is running (the values are given in the table below);

pi The absolute initial pressure, equivalent to the pre-charge pressure of the buffer tank (normally 2.5 bar, i.e. 1.5 bar-r);

pf The absolute tolerated pressure, which must be less than the pressure at which the safety valve is set, taking account of any difference in height between the valve and the tank.

The total capacity of the buffer tank is expressed as: using the expansion coefficient values in the following table.

Vt = C ⋅ e

PARTIAL HEAT RECOVERY

Partial heat recovery is through two shell and tube exchangers fitted before the condensers. The below drawing indicates the partial heat recovery circuit fitted inside the unit, recommended circuit for user. In order to ensure the correct functioning of the chillers avoid that the heat recovery plate exchanger D is powered by water which is too cold (>35°C). For this reason use of a three way valve VMA is strongly advised yet remains the responsibility of the installer (see diagram).

TOTAL HEAT RECOVERY

In the AQUAFLAIRB.R.A series, total heat recovery is achieved by means of two independent parallel circuits, each of which consists of a shell and tube heat exchanger. This option means heat that would otherwise be released outside by the condenser is used to produce hot water, typically for domestic use.

COOLING ONLY SERIES

In the cooling only series (BRAC end BRAT), total heat recovery is achieved based on two parallel circuits, each illustrated in the following diagram: if you wish to produce hot water, the three-way valve (B) diverts refrigerant through the recovery unit (E) - where condensation heat is released - instead of through the condenser (D).

BRAC • basic version

Continuous speed control of one bank of fans up to 880 rpm; ON-OFF control on other bank (maximum speed:880 rpm)

• standard version with low ambient temperature option Continuous speed control of fans belonging to both banks up to 880 rpm;

• low-noise version Continuous speed control of one bank of fans up to 660 rpm; ON-OFF control on other bank (maximum speed: rpm)

• low-noise version with low ambient temperature option Continuous speed control of fans belonging to both banks up to 880 rpm

BRAT • basic version

Continuous speed control of one bank of fans up to 880 rpm; ON-OFF control on other bank (maximum speed:880 rpm)

• low-noise version Continuous speed control of one bank of fans up to 660 rpm; ON-OFF control on other bank (maximum speed: 660 rpm)

• ultra-low-noise version with low ambient temperature option Continuous speed control of fans belonging to both banks up to 550 rpm;

BRAF • basic

Continuous speed control of fans belonging to both banks up to 880 rpm; • low-noise

Continuous speed control of fans belonging to both banks up to 660 rpm;

BRAM • basic

Continuous speed control of fans belonging to both banks up to 550 rpm.

LOCAL USER TERMINAL (mP20II)

It completes standard unit and permit the programming of the control parameters (set points, differentials, alarm thresholds) and the displaying of data and events (set point readings, monitored values, function events and alarms).

REMOTE USER TERMINAL (mP20II)

It is possible to specify a remote control which allows direct entering of commands to the chiller; this can be positioned up to 200 metres (with shielded cable) away and enables the display and modification of parameters, settings and alarm states; a wall fixing kit is available for remote fitting.

LOCAL NETWORK CONNECTION AQUAFLAIR

B.R.A. units can be interconnected with each other to form a local area network, thus giving the range an additional degree of flexibility. There are two kinds of connection: Interconnected management of n chillers (up to 10) and Management of a group of chillers (up to 10, with one or two backups units). With interconnected management, you can connect two control cards with each other and use a single user terminal to manage the units as though they were a single device, sharing settings, general compressor rotation, and overall trouble management. By managing the compressors, up to 12/16 cooling steps can be achieved, thus optimising energy consumption. Rotation, in particular, is based on FIFO logic: each time, the compressor that has been off for longest is switched on first, meaning hours of operation are distributed evenly to achieve uniform ageing. If more than two chillers (possibly to manage one or two standby units) and up to ten units at most (with one or two backup units) are connected on the same hydraulic system, group management can be used by connecting all the cards together and using a single user terminal to manage units as though they were a single device, sharing settings, general compressor rotation, overall trouble management etc.

The local network uses high-speed RS485 communication (64 kByte/s) with 2-core shielded telephone cable.

SUPERVISION SYSTEMS CONNECTION

AQUAFLAIRB.R.A. range chillers are conceived and designed to be installed in a LAN managed by supervision

systems. Hence they are compatible with the more common external BMS protocols. i.e.:

EXTERNAL BMS COMPATIBILITY

• Modbus (no limit for number of connected units; every unit is equipped with a RS485 card); • Bacnet (Max 8 units; every unit is equipped with a RS485 card; note with Bacnet GTW); • LONworks (no limit for number of connected units; every unit is equipped with a FTT10 card); • TREND (with optional TREND card); • Metasys (possible with database integration and Application Note JCI); • SNMP (Max 16 units; every unit is equipped with a RS485 card; note with Webgate); • TCP/IP (Max 16 units; every unit is equipped with a RS485 card; note with Webgate).

UNIFLAIR SUPERVISION

NETVISOR is UNIFLAIR’S new supervision system that enables the supervision of all Uniflair products through the connection of TCP/IP protocol network (Ethernet Network). UNIFLAIR’S NETVISOR has a "WEB based" graphical interface, i.e. that can be visualised as a WEB page, through the use of any Internet browser (ex. Internet Explorer 5.0 or advanced versions). Please note that the browser and the NETVISOR must be installed on the same PC. UNIFLAIR’s NETVISOR supervision system is based on the connection between the units to control (chillers, precision air conditioning units, telecom units) and an RS485 line. Uniflair offers 3 different types of supervision systems that need different devices in order to manage RS485 line. Units connected to a local supervision system: the connection is managed by a local PC (using a serial adaptor RS485/RS232) where the local UNIFLAIR NETVISOR is installed. Units connected to a remote supervision system: the connection is managed through PLANTWATCH; this is a wall-control system equipped with a display and a keyboard. PLANTWATCH can save historical events and signal the alarm events on connected units.

PLANTWATCH is available in two versions, without internal modem (basic version) or with a PSTN internal modem. PLANTWATCH (both versions) can connect, via modem, to a remote PC (where UNIFLAIR NETVISOR remote is installed) in order to signal alarm events and to upload historical data. Moreover, it is possible to connect from a remote PC to PLANTWATCH in order to monitor (in remote) the units or to download historical data.

Versione 01.1 del 07.05.2004 41

Uniflair also supplies a remote monitoring configuration; this solution combines the advantages of local and remote supervision: local PC manages RS485 line (using NETVISOR local) and it can connect to a remote PC (equipped with NETVISOR remote).

NETVISOR manages analogic PTSN modem and GSM modem for sending FAXES or SMS. Moreover, NETVISOR can be used as a WEB server, i.e. via PC’s connected with Ethernet networks using an Internet browser in order to download WEB pages that visualise unit data. This operation is also possible through the use of WEBGATE that manages RS485 line and is connected with Ethernet networks as WEB server (with a specific IP address). Local or remote PC (not supplied by Uniflair) requirements: microprocessor Pentium III, 64Mb RAM, USB adaptor and serial adaptor (COM) free, O.S. Windows 98, NT, 2000, XP.

FREE-COOLING SERIES

When the chiller is used for the cooling of technological systems which operate in all seasons, new BRAF and BRAM chillers series have free-cooling function that can significantly reduce energy consumption.

In chillers belonging to said series, free-cooling system is implemented. Using this system, when external temperature is sufficiently low, there is no need to use the “cooling” part of the chiller, namely the compressors, which are the components responsible for most energy consumption. In these units, chilled water is actually produced using external air, meaning the only energy required is that demanded by the fans.

With this method, chilled water can be provided at no cost.

AQUAFLAIRB.R.A. units, like all other Uniflair products, give you the option of using free cooling even when

external temperature is not sufficient to ensure that heat is removed altogether. In these cases, the resulting operating mode is called mixed: the chiller will use external air to pre-cool the refrigerant, subjecting compressors to less strenuous duty, again achieving energy savings. Hence there will be three operating conditions, represented in schematic form in the diagram below: Hence there will be three operating conditions, represented in schematic form in the diagram below:

• Free-cooling (fans and freecooling pump operating); • Mixed (fans and freecooling pump operating, and compressors operating in part); • Mechanical cooling (Direct expansion) (fans and compressors operating).

THEORY OF OPERATION

The idea behind the free-cooling mode is, as mentioned above, that of producing chilled water using external air instead of direct expansion operation.

The microprocessor control system, when external air temperature is sufficiently low, enables free-cooling mode: water is circulated by the f.c. pump inside special heat exchange coils and cooled by external air forced in by fans, which, together with the pump, are the only components absorbing energy. The water is then conveyed back into the circuit and supplied to the equipment.

A. Free-Cooling pump B. Free-Cooling coil C. Condenser coil D. Scroll compressor E. Evaporator

Bear in mind that an installation’s heat load - i.e. the amount of “cold” energy required - depends on both the heat generated inside it (hence machinery, people, lights…) and external temperature. Generally, therefore, the heat load in summer will be greater than in the winter months. Based on this premise, we can reasonably assume that if the chilled water produced must have a temperature of approx. 7°C during the warmer months, during the colder months Toutlet water = 10°C may be sufficient.

Based on these presuppositions, the unit can work in full free-cooling mode with a Texternal as high as 5°C.

Nonetheless, there is a temperature range within which - even though production of water at 10°C cannot be assured with free-cooling mode alone - it is still best to use the f.c. coils to pre-cool water returned from the equipment, hence making the cooling part “work” less, thus achieving energy savings.

The range in question varies depending on the model and load, though we can assume it will be from 5°C to 15°C.

To sum up, operating ranges for BRAF/M units can be split into:

• Freecooling, with Text < 5°C • Mixed, with 5°C < Text < 12 to 15°C • Mechanical cooling (direct expansion) with Text > 12 to 15°C

The above graph can be completed with these data:

PRECISION ON OUTLET WATER TEMPERATURE CONTROL

In the new series from the AQUAFLAIRB.R.A. range, control of temperature introduced into the hydraulic circuit of the equipment served is applied on water at the outlet. This means the desired temperature can be achieved with a high level of accuracy, at the same time safeguarding the compressors and their minimum switch-on times courtesy of a specially designed control system.

The data below refer to an installation without said tank with a minimum output per kW of 2.5 l/kW.

NOISE LEVEL

True to its policy of producing units with low noise emission levels, UNIFLAIR has created the new AQUAFLAIR

B.R.A range, which also reflects the company’s pursuit of unbeatable flexibility. The resulting versions offer low noise levels whilst favouring low cost, high performance or silent running. These versions are:

BRAC – cooling only series

• Basic These kinds of units feature continuous speed control for fans associated with one circuit, whilst the rest are controlled in ON-OFF mode. This gives priority to capacity, controlling noise emitted by the unit when the external temperature is lower.

• Low-noise These kinds of units feature continuous speed control for fans associated with one circuit, whilst the rest are controlled in ON-OFF mode. For all, however, the maximum speed that can be reached is limited in favour of low noise emission, especially when external temperature is lower. Moreover, these units feature soundproofing coverings for Scroll compressors and a sound-insulating enclosure teamed with vibration dampers for screw compressors.

BRAT – cooling only series for high ambient temperature • Basic

These kinds of units feature continuous speed control for fans associated with one circuit, whilst the rest are controlled in ON-OFF mode. This gives priority to capacity, controlling noise emitted by the unit when the external temperature is lower. Moreover, these units can be fitted with soundproofing coverings for Scroll compressors and a sound-insulating enclosure teamed with vibration dampers for screw compressors.

• Low-noise These kinds of units feature continuous speed control for fans associated with one circuit, whilst the rest are controlled in ON-OFF mode. For all, however, the maximum speed that can be reached is limited in favour of low noise emission, especially when external temperature is lower. Moreover, these units feature soundproofing coverings for Scroll compressors and a sound-insulating enclosure teamed with vibration dampers for screw compressors.

• Ultra low noise Units in this version come with continuous speed control for all fans. This means they can be controlled precisely and thus their speed, and hence noise emitted, can be minimized: adjustment is closely linked to variations in external temperature, especially if it drops. Moreover, these units feature soundproofing coverings for Scroll compressors and a sound-insulating enclosure teamed with vibration dampers for screw compressors.

BRAF – freecooling series

Units belonging to this series come with continuous speed control for all fans.This means they can be controlled precisely and thus their speed, and hence noise emitted, can be minimized: adjustment is closely linked to variations in external temperature, especially if it drops. The difference between the two versions lies in the maximum speed that the fans can reach and whether or not compressor soundproofing is standard issue.

• Basic This version can be fitted with soundproofing coverings for Scroll compressors and a sound-insulating enclosure teamed with vibration dampers for screw compressors.

• Low-noise This version features soundproofing coverings for Scroll compressors and a sound-insulating enclosure teamed with vibration dampers for screw compressors.

BRAM – ultra-low-noise freecooling series

• Ultra-low-noise basic Units belonging to this series come with continuous speed control for all fans.This means they can be controlled precisely (limited to a maximum of 550 rpm at all times) and thus their speed, and hence noise emitted, can be minimized: adjustment is closely linked to variations in external temperature, especially if it drops. Moreover, soundproofing coverings for Scroll compressors and a sound-insulating enclosure teamed with vibration dampers for screw compressors are standard issue on these units.

NOISE PRESSURE LEVEL

SOUND PRESSURE levels are measured with units working at full load, free-field conditions with Q=2, 10m away fromthe unit, on the coil side, at a height of 1m above the ground.

NOISE PRESSURE LEVEL TAKEN AT DIFFERENT DISTANCES OR POSITIONS

It is possible to calculate the noise pressure level at the desired distance or unit side: electrical board side or back side

MANUTENZIONE E SOSTITUZIONE COMPONENTI

REFRIGERANT CHARGE

Units are pre-charged in the factory and do not need re-charging unless there have been problems during transport or installation or the safety valve has intervened. In the event that it is necessary to adjust the charge, follow the instructions below. If the circuit has been drained for the replacement of components, a vacuum must be created in the circuit before re-charging.

CREATING A VACUUM IN THE CIRCUIT Connect the vacuum pump to the valves in the compressor housing and take the vacuum in the system to 0.3 mbar; remember that the vacuum must not be created too quickly (at least 120 minutes). When the vacuum level is reached, maintain it for at least 60 minutes.

4 ELECTRICAL CONNECTION

82 Versione 01.1 del 07.05.2004

4.1 GENERAL RECOMMENDATIONS

Compressor and electrical accessories are in accordance with the EC Low Voltage Directive 73/23/EEC (CE 96). The electrical installation is to be carried out according to the wiring diagram in the terminal box and in the Manual SH-170. Observe the safety standards EN 60204, EN 60335 and national safety regulations.

Attention! Danger of severe compressor damage! Cut out holes for cable bushings carefully! Cable bushings must be leakproof to keep condensing water from developing in the terminal box. For the dimensions of the motor con-tactors, cables and fuses:

Attention! Maximum operating current or max. power consumption of the motor should be the base. See name plate or Manual SH-170. Contactor selection: according to operational category AC3. Voltage and frequency data on the name plate should be compared to the electrical supply data. The motor may only be connected when these coincide. Wire the motor terminals according to the indications on the terminal box cover. With part winding motor observe closely part winding order! First part winding (contactor K1): connections 1 / 2 / 3 Second part winding (contactor K2): connections 7 / 8 / 9 Time delay before connection of the second part winding 0.5 sec.

Attention! Danger of motor damage! Wrong wiring results in opposing or displaced rotating fields due to changed phase angle. This leads to locked rotor conditions. Mount connections correctly!

Attention! Danger of insulation damage and motor burn-out! Do not at all repeat the highvoltage test in the same way! However testing with reduced voltage is possible (e. g. 500 V). Among others this restriction is due to the impact of oil and refrigerant on the dielectric strength.

4.2 PROTECTION DEVICES

Motor protection devices Attention!

Break-down of the motor protection device possible! Terminals T1-T2 on the compressor and 3 / 4 / 5 on the terminal strip must not come into contact with the control or supply voltages!

INT69VSY-II is mounted inside the terminal box. The cables for the motor and oil temperature PTC sensors are already connected. D1 must be connected correctly, otherwise there will be no rotation monitoring! Remove bridge D1-L. (Fig. 6). Other connections should be made according to the wiring diagram in the terminal box and in the Manual SH- 170.

Pressure limiters (HP & LP)

Are necessary in order to limit the operating range of the compressor to avoid inadmissible operating conditions. For connection positions see page 9. By no means pressure limiters may be connected to the service connection of the shut-off valve! Monitoring the oil circuit Indirect monitoring by means of oil temperature sensor (standard) is only sufficient for short circuits with small system volumes and refrigerant charges. Oil heater ensures the lubricity of the oil even after long standstill periods. It pre-vents increased refrigerant solution in the oil and therefore reduction of viscosity.

Versione 01.1 del 07.05.2004 83

It is mounted in a sleeve and can be replaced if necessary without opening the refrigerating circuit.

The oil heater must be energized during the standstill for: • outdoor installation of the compressor • long shut-off periods • high refrigerant charge • danger of refrigerant condensation into the compressor

Connections according to the wiring diagram.

5 COMMISSIONING

The compressor is already thoroughly dehydrated, tested for leaks and under pressure with holding charge (N 2 ).

Attention! Test the strength pressure and the tightness of the entire plant preferably with dry nitrogen (N 2 ). Compressor must be put out of circuit when using dried air –keep the shut-off valves closed. Danger! By no means the compressor may be pressure tested with oxygen or other industrtial gases!

Warning! Never add refrigerant to the test gas (N 2 or air) – e. g. as leak indicator. Critical shift of the refrigerant ignition limit with high pressure possible! Environmental pollution with leakage or when deflating!

5.2 Tightness test

Evaluate tightness of the entire refrigerant circuit (assembly) or parts of it according to EN 378-2 (or valid equivalent safety standards) by using preferably an overpressure of dry nitrogen at 15 bar.

Danger! Test pressures and safety references see chapter 5.1. For testing the strength pressure or tightness with dry air

Attention! The compressor must not be pressurized with air! Keep the service valves closed. The compressor is already thoroughly dehydrated, tested for leaks and under pressure with holding charge (N 2 ).

5.3 EVACUATION

Energize the oil heater. Open all shut-off valves and solenoid valves. Evacuate the entire system including compressor using a vacuum pump connected to the high and low pressure sides. When the pump is switched off a "standing vacuum" of less than 1.5 mbar must be maintained. If necessary repeat this procedure several times.

Attention! Danger of motor and compressor damage! Do not start compressor under vacuum! Do not apply any voltage – not even for test purposes!

5.4 REFRIGERANT CHARGING

Charge only nitrogen. • Before refrigerant is charged: - Energize the oil heater. - Check the compressor oil level. - Do not switch on the compressor! • Charge liquid refrigerant directly into the condenser resp. receiver. For systems with flooded evaporator refrigerant can be also charged into the evaporator. • After commissioning it may be necessary to add refrigerant:

84 Versione 01.1 del 07.05.2004

Charge the refrigerant from the suction side while the compressor is in operation. Charge preferably at the evaporator inlet. Blends must be taken from the charging cylinder as "solid liquid". If liquid is charged:

Attention! Danger!

Danger of wet operation! Charge small amounts at a time! Keep the discharge temperature at least 30 K (R22, R407C) or at least 20 K (R134a, R404A, R507A) above ondensing tem-perature.

Explosion risk of components and pipelines by hydraulic over-pressure. Avoid absolutely overcharging of the system with refrigerant!

5.5 CHECKS BEFORE STARTING

• Oil level (within sight glass range) • Temperature of the oil separator: at least 15 K above ambient temperature Measuring point: Bottom side of the vessel, approx 10 cm distance from the flange • Setting and function of safety and protection devices • Setting of time relays • Cut-out pressures of the high- and low-pressure limiters • Are the shut-off valves opened? When exchanging a compressor:

Attention! Oil is already in the system. Therefore it may be necessary to drain a part of the oil charge. If there are large quantities of oil in the circuit (possibly from a preceding compressor damage), there is also a risk of liquid slugging at start. Adjust oil level within the sight glass range! Additional measures when replacing a reciprocating compressor:

Attention! Danger of compressor damage! The new oil has a higher viscosity and a strong solvent effect within the refrigerating circuit. • Mount a suction side cleaning filter (filter mesh 25 m).

Attention! Danger of compressor damage! Use a filter with perforated metal tubes around the inside and outside diameter of the filter element – suitable for bidirectional operation. • Replace oil and suction side cleaning filter after a few operating hours. • Repeat this procedure if required. See also chapter 6.2.

5.6 START-UP PROCEDURE

CHECKING THE ROTATING DIRECTION

Attention! Danger of severe compressor damage! Operate screw compressors only in the prescribed rotating direction! In spite of the phase sequence control by the INT69VSY-II protection device a test is recommended.

Phase sequence test with mounted suction shut-off valve: • Connect a gauge to the suction shut-off valve. Close the spindle and then open one turn. • Start the compressor only briefly (approx. 0.5 .. 1 s). • Correct rotating direction: Suction pressure drops immedia-tely. • Wrong rotating direction: Pressure increases or the protection device shuts off. Change over two phases at the terminals of the common supply line.

Phase sequence test without suction shut-off valve: • Close the solenoid valves (evaporator and economiser).

Versione 01.1 del 07.05.2004 85

• Start the compressor only briefly (approx. 0.5 .. 1 s). • Considerably less changes in pres-sure as with choked suction shut-off valve. • Correct rotating direction: Suction pressure drops. • Wrong rotating direction: Pressure remains unchanged, increases or the protection device shuts off. Change over two phases at the terminals of the common supply line.

Start-up Start the compressor again and slowly open the suction shut-off valve.

Lubrication / oil check The compressor lubrication should be checked immediately after starting. • Oil level within sight glass range or slightly below (repeat checks with-in the first hours of operation). • Oil foam can be generated during the starting phase, but should reduce under stable operating conditions. Otherwise this can indicate excessive liquid in the suction gas.

Attention! Danger of wet operation! Discharge temperature must be at least 30 K ( R407C) or at least 20 K (R134a, R404A, R507Aabove condensing temperature. If larger quantities of oil must be added: Setting of the condenser pressure control

Attention! Danger of liquid slugging! Check the oil return. Setting the high and low pressure limiters (HP & LP) Check exactly switch-on and cutout pressures by experiment according to the operating limits.

The condenser pressure must be set so that the minimum pressure difference is reached within 20 s after starting (see application limits in the Manual SH-170 or BITZER software). Rapid reduction in pressure must be avoided by a sensitive pressure control. Checking the operating data • Evaporating temperature • Suction gas temperature • Condensing temperature • Discharge gas temperature - at least 30 K (R22, R407C) or at least 20 K (R134a, R404A, R507A) above condensing temp., - max. 120°C outside the discharge pipe • Oil temperature - at bottom side of oil separator • Switching frequency Prepare data sheet. Application limits see Manual SH-170 or BITZER software.

Attention! Danger of severe compressor damage! The following requirements must be ensured by the control logic: Returning time of the control slide – CR3 (Y3) energized • Maximum cycling rate 6 to 8 starts per hour! • 5 minutes minimum operating time desired! • Switch-over time part winding 0.5 s star delta 1 s

Vibrations The whole plant especially the pipe lines and capillary tubes must be checked for abnormal vibrations. If necessary additional protective measures must be taken.

Attention! Pipe fractures and leakages at compressor and other components of the plant possible! Avoid strong vibrations!

6 OPERATION / MAINTENANCE

6.1 REGULAR CHECKS

Examine regularly the plant according to national regulations. The following points should also be checked: • Operating data (chapter 5.6) • Lubrication / oil check (chapter 5.6)

86 Versione 01.1 del 07.05.2004

• Protection devices and all compressor monitoring parts (see chapters 4.2 and 5.6) • Integrated check valve • Update data protocol.

Internal pressure relief valve

The valve is maintenance free. Repeated opening of the valve due to abnormal operating conditions, however, may result in steady leakage. Consequences are losses in capacity and increased discharge temperature. Check and replace the valve in this case. In the CSH85 models two valves are incorporated. Integrated check valve After shut-off the compressor runs backwards for a short time (until pressure equalisation in the oil separator occurs). When the valve is faulty or dirty the runnig back time will increase. In this case the valve must be replaced.

Warning! Compressor is under pressure! Serious injuries possible. Release the pressure in the compressor! Wear safety goggles! Fitting position: Flange at the discharge gas outlet of the oil separator First remove the discharge shut-off valve. Detailed information see Maintenance Instruction SW-170.

6.2 OIL CHANGE

The oil types listed in chapter 2 are characterised by an especially high degree of stability. If the plant is correctly assembled, or if fine filters are installed on the suction side an oil change is not normally needed. If compressor or motor damage occurs an acid test should be made. When required clean up measures must be made: Mount an acid retaining (bi-directional) suction line gas filter and replace the oil. Purge the plant from the highest point on the discharge side into a recycling cylinder. After a few operating hours it may be necessary to replace filter and oil and to purge the plant again. Replacing the oil: Drain the oil out of the oil separator and compressor motor chamber (see figure 7).

Warning! Compressor is under pressure! Serious injuries possible. Release the pressure in the compressor! Wear safety goggles! Oil types: See chapter 2.

Fig. 7 Oil drain positions

Attention! Ester oils are strongly hygroscopic. Moisture is chemically compounded with these oils. It can-not be, or only insufficiently, removed by evacuation. Handle very carefully! Avoid air admission into the plant and oil can! Dispose of waste oil properly! Chlorinated oil is pollutive waste.

7 DE-COMMISSIONING

7.1 STANDSTILL

Versione 01.1 del 07.05.2004 87

Keep the oil heater switched on until dismantling the compressor! This prevents increased refrigerant solution in the compressor oil.

7.2 DISMANTLING THE COMPRESSOR

For repair work, that makes dismantling necessary, or when decommissioning them: Close the shut-off valves at the compressor. Pump-off the refrigerant. Do not release the refrigerant but dispose it properly!

Warning! Compressor can be under pressure! Severe injuries possible. Wear safety goggles! Open the threaded joints or flanges at the compressor valves. Remove the compressor if necessary with a hoisting tool. Disposing the compressor Drain the oil at the compressor. Dispose of waste oil properly! Chlorinated oil is pollutive waste. Have the compressor repaired or disposed of properly!
