TECHNICAL SPECIFICATIONS
dedicated heat exchanger and additional piping to carry the oil from the compressor to heat exchanger and
viceversa will be not accepted.
•
The compressor shall be provided with an integrated, high efficiency, cyclonic type oil separator and with built-
in oil filter, cartridge type.
•
The compressor shall be direct electrical driven, without gear transmission between the screw and the electrical
motor.
•
The compressor casing shall be provided with ports to realize economized refrigerant cycles.
•
The economizer cycle shall be provided with electronic expansion valve
•
The unit shell be provided with two thermal protection realized by a thermistor for high temperature protection:
one temperature sensor to protect electrical motor and another sensor to protect unit and lubricating oil from
high discharge gas temperature.
•
The compressor shall be equipped with an electric oil-crankcase heater.
•
Compressor shall be fully field serviceable. Compressor that must be removed and returned to the factory for
service shall be unacceptable.
Cooling capacity control system
The chiller will have a microprocessor for the control of the compressor capacity through inverter in order to
continuously modulate the compressor’s rotational speed.
•
The unit capacity control shall be infinitely modulating between 100% and the minimum. The chiller shall be
capable of stable operation to minimum capacity without hot gas bypass.
•
The system shall control the unit based on the leaving evaporator water temperature that shall be controlled
by PID (Proportional Integral Derivative) logic.
•
Unit control logic shall to manage frequency level of the compressor electric motor to exactly match plant load
request in order to keep constant the set point for delivered chilled or hot water temperature.
•
The microprocessor unit control shall detect conditions that approach protective limits and take self corrective
action prior to an alarm occurring. The system shall automatically reduce the chiller capacity when any of the
following parameters are outside their normal operating range:
-
High condenser pressure
-
Low evaporating refrigerant temperature Unit-mounted Compressor’s Inverter and Electrical Requirement
Customer electrical connection for compressor motor power shall be limited to the main power lead to the single
point power connection located into electrical panel.
•
The Inverter shall be refrigerant cooled. Water cooled or air cooled inverter cooling are not acceptable.
•
Base motor frequency shall permit motor to be utilized at nameplate voltage. Adjustable frequency range,
monitored by unit’s microprocessor control, shall permit a stable unit capacity control down to minimum capacity
without hot-gas bypass.
•
Unit displacement power factor shall be not less than 0.95 on entire unit capacity range, from 100% down to
minimum capacity.
Evaporator
(Single circuit unit)
The units shall be equipped with a direct expansion plate to plate type evaporator.
•
The evaporator will be made of stainless steel brazed plates and shall be linked with an electrical heater
controlled by a thermostat and shall be insulated with flexible, closed cell polyurethane insulation material.
•
The evaporator will have 1 refrigerant circuit for each compressor.
•
The water connections shall be VICTAULIC type connections as standard to ensure quick mechanical
disconnection between the unit and the hydronic network.
•
The evaporator will be manufactured in accordance to PED approval.
•
Flow switch on evaporator available as option (shipped loose).
•
Water filter will be standard. (Dual Circuit units)
The units shall be equipped with a direct expansion shell & tube evaporator with copper tubes rolled into steel
tube sheets. The evaporator shall be single-pass on both the refrigerant and water sides for pure counter-flow
heat exchange and low refrigerant pressure drops.
•
The external shell shall be linked with an electrical heater to prevent freezing down to -28°C ambient
temperature, controlled by a thermostat and shall be insulated with flexible, closed cell polyurethane insulation
material (20-mm thick).
•
The evaporator will have 2 circuits, one for each compressor and shall be single refrigerant pass.
•
The water connections shall be VICTAULIC type connections as standard to ensure quick mechanical
disconnection between the unit and the hydronic network.
•
The evaporator will be manufactured in accordance to PED approval.
•
Flow switch on evaporator available as option (shipped loose).
•
Water filter needs to be provided on the plant.
Condenser coil The condenser is made entirely of aluminum with flat tubes containing small channels. Full depth
louvered aluminum fins are inserted between the tubes maximizing the heat exchange. The Microchannel
technology ensures the highest performance with the minimum surface for the exchanger. The quantity of
refrigerant is also reduced compared to Cu/Al condenser. Special treatments ensure resistance to the
