TECHNICAL SPECIFICATIONS
Condenser fans
The condenser fans used in conjunction with the
condenser coils, shall be propeller type with glass reinforced
resin blades for higher efficiencies and lower sound. Each fan shall be protected by a fan guard.
• The air discharge shall be vertical and each fan must be coupled to the electrical motor, su
pplied as standard to IP54 and capable to
work to ambient temperatures of - 20°C to + 65°C.
• The condenser fans shall have as a standard an internally protection from overtemperature.
Refrigerant circuit The unit shall have two refrigerant circuits.
• The circuit shall include as standard: electronic expansion device piloted by unit’s microprocessor control, liquid line shut-
off valve,
sight glass with moisture indicator, replaceable filter drier, charging valves, high pressure switch, high and low pre
ssure transducers
and insulated suction line.
Condensation control
The units will be provided with an automatic control for condensing pressure which ensures the working
at low external temperatures down to - …………… °C, to maintain condensing pressure.
• The unit automatically unloads when abnormal high condensing pressure is detected. This to prevent the shutdown of the refriger
ant
circuit (shutdown of the unit) due to a high-pressure fault.
Low sound unit configurations (on request)
The unit compressor shall be connected with unit’s metal base frame by
rubber antivibration supports to prevent the transmission of vibrations to all metal unit structure, in order to control the unit sound.
• The chiller shall be provided with an acoustical compressor enclosure. This enclosure shall be realized with a light, corrosi
on resisting
aluminum structure and metal panels. The compressor sound-proof enclosure shall be internally fitted with flexible, multi-
layer, high
density materials.
Hydronic kit options (on request) The hydronic module shall be integrated in the chiller chassis without increasing its
dimensions and includes the following elements: centrifugal pump with motor protected by a circuit breaker installed in control panel,
water filling system with pressure gauge, safety valve, drain valve.
• The hydronic module shall be assembled and wired to the control panel.
• The water piping shall be protected against corrosion and freezing and insulated to prevent condensation.
• A choice of two pump types shall be available:
- in-line single pump
- in-line twin pumps.
Electrical control panel
Power and control shall be located in the main panel that will be manufactured to ensure protection
against all weather conditions.
• The electrical panel shall be IP54 and (when opening the doors) internally protected against possible accidental contact wi
th live
parts.
• The main panel shall be fitted with a main switch interlocked door that shuts off power supply when opening.
• The power section will include compressors and funs protection devices, compressors and fans starters and control circuit p
ower
supply.
Controller The controller will be installed as standard and it will be used to modify unit set-points and check control parameters.
• A built-
in display will shows chiller operating status plus temperatures and pressures of water, refrigerant and air, programmable
values, set-points.
• A sophisticated software with predictive logic, will select the mos
t energy efficient combination of compressors, EEXV and condenser
fans to keep stable operating conditions to maximize chiller energy efficiency and reliability.
• The controller will be able to protect critical components based on external signals from it
s system (such as motor temperatures,
refrigerant gas and oil pressures, correct phase sequence, pressure switches and evaporator). The input coming from the high
pressure
switch cuts all digital output from the controller in less than 50ms, this will be an additional security for the equipment.
• Fast program cycle (200ms) for a precise monitoring of the system.
• Floating point calculations supported for increased accuracy in P/T conversions.
