1. Elctrical panel : Contains all electrical (main disconnect, inductances, filters, fuses) and electronic components.
2. Compressors : State of the art frictionless two-stages centrifugal compressor, magnetic bearing, of the Dafoss
Turbocor series
3. Evaporator : Flooded shell and tube heat exchanger for all models, with chilled water flowing inside tubes and
refrigerant changing phase from liquid to vapour shellside.
4. Condenser : Flooded shell and tube heat exchanger for all models, with cooling water flowing inside tubes and
refrigerant changing phase from vapour to liquid shellside.
5. Expansion valve : An electronic expansion valve, which is controlled by an electronic device, that optimises its
operation keeping the refrigerant mass flow at the right value
Description of the refrigeration cycle
The low-temperature refrigerant gas from the evaporator is drawn by on or two centrifugal compressors and compressed.
The high-pressure refrigerant gas is sent to the condenser where, flowing shell-side, the superheated refrigerant vapour
cools down and starts to condense and then the liquid is subcooled in the lower part of the condenser.
The heat taken from the fluid during the de-superheating, condensation and subcooling phase is transferred to the
cooling water.
The subcooled fluid flows the expansion element valve and pressure drops resulting in the vaporisation of part of the
refrigerant liquid.
The result at this point is a low-pressure and low-temperature liquid-gas mixture entering the evaporator, where, flowing
shell-side, it takes the heat required for vaporisation exchanging heat with the water to be cooled, thus reducing the
water temperature.
Once it has reached the superheated-vapour state, the refrigerant leaves the evaporator and is once again taken into the
compressor to repeat the cycle.
A small amount of liquid refrigerant is drawn by the condenser and sent to the compressor for the cooling oif the motor;
to valves located in the compressor motor control the motor temperature
