Aquaflair
B.R.W./R
B.R.W./R.
The AQUAFLAIR
range is composed of eleven water-cooled chillers with semihermetic double screw compressors with nominal cooling capacities ranging from 300 to 1200 kW, available
in the following series:
-
cooling only
heat pump
condenserless
Our commitment to respect environmental regulations, a commitment typical of UNIFLAIR products, is fully
maintained in these series. The units have been designed for standard operation with the refrigerant
R134a.
The BRWC/H and BRRC units are based on cutting-edge technology and include many innovative features
and details. Even the basic version, for example, includes an electronic expansion valve.
The unit is fully 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.
The following items complete the hardware: a LAN card and a Clock card, both standard items, and the
serial RS485 adaptor (optional) for connection to the Uniflair supervision system or to a Building
Management System.
The design criteria of B.R.W.-R.* models is based on three key words: efficiency, reliability and flexibility.
Twin screw compressors, R134a refrigerant and Electronic Expansion Valves allow high energy efficiency in
all operating conditions.
Great attention has been paid to the creation of a completely flexible system: the footprint is one of the
smallest available, with a width and height which allows the units of up to 700kW to pass through a standard
doorframe.
These chillers can be supplied in a low-noise version, recording noise emission values among the lowest in
the category.
The units can also be installed externally and can operate with condensation water temperatures of up to
55°C.
Particular attention has been paid to reliability, both in the choice of components for adjustment / control:

MAIN FEATURES
MAIN FEATURES
B.R.W./R.
AQUAFLAIR
condenserless units are designed for INTERNAL installation (or external installation but it
must be protected from rain; for example with a shed) in residential, commercial and technological applications.
The chilled water which is produced can be sent to the 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, a local area network can be
created which links the microprocessor control boards, creating solutions to satisfy all needs.
B.R.W./R.
AQUAFLAIR
water chillers and heat pumps feature state-of-the-art technology allowing maximum
reliability, safety, quietness of operation and respect for the environment.
EASY TO INSTALL AND TO MAINTAIN
All models are fitted with a general door interlock switch allowing direct connection to the mains power supply
without the need for an external switch; short-circuit protection fuses should, however, be fitted in order to protect
the power supply line.
Water chillers and heat pumps are assembled and fully tested in the factory, making installation simply a question
of connection to the electrical power supply and water circuits.
Particular attention has been paid to planning the position of the components to allow easy access for ordinary
and emergency maintenance.
(
Finally, the units have been produced in order for then to also be installed externally On request).
FOOTPRINT
Particular attention has been paid to creating a completely flexible installation: the footprint of this unit is one of
the smallest available, with a width and height which allow units of up to 750kW to pass through a standard
doorframe.
RESISTANCE TO THE ELEMENT
Corrosion resistance is an essential feature of UNIFLAIR units. They are built to operate even under extremely
severe environmental conditions. The self-standing framework is made of galvanised sheet steel, with panels
painted with epoxy powder paints (colour RAL 7037) conforming to the ASTM B117 standard. Furthermore, all
external screws, nuts, etc are in stainless steel.
ENVIRONMENTALLY FRIENDLY
B.R.W./R.
UNIFLAIR products have always been built with respect for the environment. With the AQUAFLAIR
range,
UNIFLAIR continues to offer solutions which are at the forefront of technology and which are aimed at reducing
environmental impact. These solutions cover many aspects: use of the ecological refrigerant R134a, elimination of
non-recyclable materials, lower consumption of energy by using components with improved thermo-dynamic
efficiency and adopting compressors with high energy performance.
ENERGY EFFICIENCY
B.R.W./R.
The AQUAFLAIR
units are designed in order to obtain maximum performance levels with minimum
energy absorption. Such a result is made possible by the use of 8-step partialisazion in the units.
The thermal range in each exchanger drops at partial pressure loads in each refrigerating circuit. This leads to an
increase of the evaporation temperature and a reduction of the condensation temperature, resulting in a very high
COP (Coefficient Of Performance).

MAIN COMPONENTS
ELECTRIC PANEL
The panel is built to conform to the 2006/95/EEC directive and to its relevant standards.
The panel has a general door interlock 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 parameters which ensure that the panel is protected by the ventilation of external air.
Furthermore, versions supplied with low ambient temperature option, include a system for controlling the
minimum internal temperature of the electrical panel by means of a self-adjusting anti-condensate electrical
heater.
Main features:
phase sequence relay, minimum voltage and asymmetrical relay
IP42 protection class (IP44 on request)
24V auxiliary circuit for the main board
230 V auxiliary circuit for compressor contactors and anti-freeze heaters (optional)
phase monitor to ensure correct screw rotation
fuse protection for each compressor against short-circuits
contactors provided for compressors;
2 voltage-free contacts for remote signalling of addressable alarms

COMPRESSORS
UNITS EQUIPPED WITH SCREW COMPRESSORS
These compressors are supplied by the market's leading
manufacturers.
They are supplied with: a 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 compressors have partial heat recovery in four steps (0 – 25 – 50 – 75 – 100%), the temperature of the
discharged water, therefore, is controlled in 8 heat recovery steps.
0%

This ensures high COP values at part loads.
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, the compressor process
can be improved by eliminating the low pressure at which the compressor normally operates. This ensures that
the COP is increased also at underpressure values, since the increase in yield is much higher than the increase
in absorbed power.
Furthermore, the units can be supplied on request with continuous modulation of refrigerating power to
further improve the COP.
In this way, the refrigerator only absorbs the energy required by the system at any time, therefore
considerably cutting down electrical consumption.
To attenuate transmission of vibrations, and therefore reduce noise levels and possible faults, each compressor
is fitted on rubber anti-vibration supports.
UNIFLAIR is a highly environmentally conscious company and has designed these units for use with HFCR134a, an environmentally friendly refrigerant.
LUBRIFICATING OIL RACCOMENDED (POE): BSE 170
CONDENSER
The units are equipped with two condensing heat
exchangers, one for each refrigerant circuit.
These shell & tube exchangers feature two water-side
passages and one refrigerant-side passage.
They are made from copper tubing and built in such a way
as to ensure high efficiency for the entire life of the
exchanger: in fact, the tube is equipped with a special spiral
which stops incrustation forming.
The units can also be supplied on request with special
condensers which are suitable for operation with sea water
(Cu/Ni tubes)

Release 1.3 – November 2012
EVAPORATOR
The removable shell & tube evaporator features two cooling circuits and a single water circuit which
operates with a very low pressure drop and is built with high-efficiency pipes in order to guarantee oil
outflow.
It is completely covered in closed-cell expanded polyurethane to prevent the formation of condensation and
to reduce thermal dispersion.
Furthermore, this material is UV resistant.
ANTI-SEISMIC SPRING ANTIVIBRATION SUPPORTS
The anti-vibration mount line is formed of:
Spring in pre-stressed steel UNI 7900 with surface protected by cataphoric treatment
2 graphite plates: a base container and an upper plate with a M24 hole
Screw TE M24 to control the level of the machine to be insulated
Guide gaskets in anti-oil elastomer allow the upper plate to slide into the base container, so to assure sonic
insulation continuity even when there are transversal thrusts
A non-slip anti-oil elastomer bearing placed on the base enables the support to withstand friction

TOTAL AND PARTIAL HEAT RECOVERY
B.R.W./R.
Total and partial heat recovery is achieved in the AQUAFLAIR
series by means of two shell and tube
heat exchangers. This option means heat which would otherwise be released outside by the condenser, is
used to produce hot water, typically for domestic use.
Total and partial heat recovery is achieved as illustrated in the following diagram: if hot water needs to be
produced, the water should be made to flow through the dedicated exchanger; in this way part or all of the
condensing occurs inside the heat recovery exchanger (R) rather than through the condenser (CN).

WIRING
(consult wiring diagram)
Before performing any work on electrical parts, make sure they are not connected
to the power supply.
In order for accidents to be prevented and for the chiller to provide good, lasting,
unaltered service, it is that essential wiring is carried out correctly, in a professional
manner and in accordance with the regulations in force.
GENERAL INSTRUCTIONS
CONNECTION TO SUPPLY MAINS
To connect the power cables, remove the cover plate on the bottom of the unit.
IP42 insulation protection must be maintained, therefore suitable cable clamps/sheath clamps and/or
junction boxes must be used.
Cables must be connected fastening the wire terminals of the cables to the relevant holes provided
for this purpose.
It is vital that the phases are connected correctly in the position indicated on the wiring diagram
which is supplied with the unit since if they are connected in any other way, the unit will not work.
Electrical connections must be made by qualified installers.
Power leads must be protected upstream against the effects of short-circuits and current overload:
Particular attention must be made to the following:
Electrical connections must be made by qualified installers.
Power leads must be protected upstream against the effects of short-circuits and current overload.
DESCRIPTION OF PROCEDURE
1) OPEN the door of the master electrical panel which is located on the front of the unit above the
compressor compartment;
2) MAKE SURE that the mains voltage matches the voltage given on the data plate of the unit (voltage,
number and frequency of the phases)
3) INTRODUCE the feeding cable through the flange indicated in the position in the diagram.
Remove the flange which is placed low on the left of unit, and make the necessary entry holes (this must be
done in such a way as to fix the cable to the upright of the unit until it reaches the electrical panel).
There is an extractable flange on the left of the base of the electrical panel and two holes on the right hand
side to allow the power supply and signal cables to enter.
a. for the power supply cables, which will be connected to the terminals on the IG general switch on the
central hand side of the electrical panel, it is necessary to unscrew the flange and make two holes
where needed.
b. for the s ignal cables, which will be connected to the terminals on the microprocessor board on
the right hand side of the electrical panel, only the plugs on the holes which have already been
made need to be removed.
The power supply lead is not supplied by UNIFLAIR S.p.A and the installer must choose an appropriately
sized cable.
The power lead’s cross-section must be chosen based on the length of the lead, how it is to be laid, the
chiller's maximum current demand, and in such a way that an excessive drop in voltage is avoided (the
supply voltage must be within ± 10% of the rated value).
The power supply connection must be supported by the entry flange provided for this purpose.

CONNECTION TO REMOTE CONDENSER
REFRIGERANT PIPING
For condenserless units with remote air-cooled or evaporating condensers, the units are supplied with a
nitrogen pre-charge.
Therefore, it is important that the unit is kept tightly closed until the remote condenser is installed and
connected to the unit.
It is the installer / contractor’s responsibility to:
size and install the system
test the piping, as well as the entire system, for leaks
evacuate the system
load the refrigerant charge
Piping
The sizing and installing of the refrigerant piping to and from the condenserless unit should be carried out
according to the procedure stated in the latest ASHRAE Handbook (see the suggested sizing in the next table).
The brazed discharge and liquid line must be carried out with all the necessary cleaning precautions
It is important that the piping has sound and vibration isolation between the tubing and the support. Moreover,
the discharge lines should be looped near the condenser and trapped near the compressor in order to prevent
refrigerant and oil draining into the compressors from the condenser.
Looping the discharge line also provides greater line flexibility.
After the equipment has been properly installed, leak tested, and evacuated, it can be charged with R134a
refrigerant and switched on.
The charge needs to be added until the liquid line sight glass is clear, with no bubbles flowing to the expansion
valve. The total operating charge will depend on the type of air-cooled condenser used and volume of the
refrigerant piping.
The discharge lines must be designed to handle oil correctly and to protect the compressor from damage caused
by liquid in the refrigerant line after the unit has been switched-off.
50 kPA should be considered the correct value for the discharge line pressure drop.
Careful consideration must be made when sizing each section of piping so that the gas is able to carry the oil in
all operating conditions.
If the gas velocity in the vertical discharge risers is too low (particularly at partial loads), a considerable amount
of oil can collect in the riser and in the horizontal headers, causing the compressor to lose its oil and
consequently being damaged by a lack of lubrication.
When the compressor load is increased, the oil collected during partial loads can be carried as a slug through the
system and back to the compressor, where a sudden increase of oil concentration may cause liquid slugging and
damage to the compressor.
Each horizontal discharge pipe should have an incline of approximately 10mm. This is necessary to move any
oil lying in the header by means of gravity. Pockets of oil must be avoided because this could prevent the
compressor receiving the correct lubrication.
Each line connecting to a horizontal discharge header should rise above its centreline. This is necessary to
prevent oil draining into the compressor when it is switched off.
Release 1.3 – November 2012
29
The addition of oil must be the same as used in the compressor (refer to page 17)
It is important that the liquid reaches the expansion valve without flash gas, since this gas will reduce the
capacity of the valve. Since “flashing” can be caused by a pressure drop in the liquid line, pressure losses due to
friction and changes in the static head should be kept to a minimum.
A check valve must be installed in the liquid line in all applications where the external temperature could drop
below the room temperature.
This prevents liquid flowing into the condenser and helps maintain a supply of refrigerant in the liquid line for
initial start-up.
Moreover, a relief valve must be used in the liquid line to relieve potentially dangerous pressures which could be
created when the cool liquid refrigerant in the line between the check valve and the expansion or shut-off
valve warms up.
Relief devices for discharge piping are installed in the factory as standard equipment.

PIPING DIAGRAM TO REMOTE CONDENSER
(for each circuit)
Liquid receiver
The receiver is used when a refrigerant storage capacity is required.
It is recommended that the receiver is installed when the remote condenser is further than 25 meters from the
internal unit.
The receiver must be installed near the BRRC unit or it may also be installed near the remote condenser if it has
a subcoling circuit.
Condenser pressure control
Since the internal BRRC unit control is not able to manage to remote air-cooled condenser fans, each remote
condenser must have its own fan speed controller based on the condensing temperature (suggested set-point
50°C).
The pressure differential between the suction and discharge compressor must be guaranteed and the
compressor must enter its field of operation within 20 seconds; to do this, the remote condenser must
be able to work in all environmental conditions with, ultimately, a pressure difference of 6.4 bar.
The figures below show a typical piping arrangement involving a remote air-cooled condenser.
Please note that the hot gas line is looped at the top and bottom of the vertical line. This is in order to prevent oil
and liquid flowing back into the compressor.
The highest point in the discharge line should always be above the highest point in the condenser coil.
It is necessary to install at the highest point a purge valve.

NOISE LEVEL - Basic version
The SOUND PRESSURE levels (measured with BRÜEL & KJǼR class 1 sound-level meter mod. 2260) for
each octave band frequency are measured with units working at full load, free-field conditions with Q=2, 1m
away from the unit according to ISO3744-3746
SOUND POWER level for each octave band frequency supplied in compliance with standard ISO3744ISO3746.
The tolerance on the data is equivalent to +/- 1.5 dB.
Note: the data supplied refers to units working based on factory settings

NOISE LEVEL - Low noise version
The SOUND PRESSURE levels (measured with BRÜEL & KJǼR class 1 sound-level meter mod. 2260) for
each octave band frequency are measured with units working at full load, free-field conditions with Q=2, 1m
away from the unit according ISO3744-ISO3746.
SOUND POWER level for each octave band frequency supplied in compliance with standard ISO3744ISO3746.
The tolerance on the data is equivalent to +/- 1.5 dB.
Note: the data supplied refers to units working based on factory settings.
