Fan
The fan draws ambient air through the evaporator.
Evaporator
The evaporator (heat exchanger) removes the heat energy from the intake air and
transfers it to the refrigerant.
Compressor
The compressor draws the refrigerant from the evaporator at low pressure and brings
it to a higher pressure and temperature level.
Condenser
The condenser (heat exchanger) is fitted in the hydraulic unit.
In the condenser, the refrigerant releases the recovered energy to the heating water.
Expansion valve
In the expansion valve, the pressure and temperature are reduced to the output level.
This allows the refrigerant in the evaporator to absorb heat again.
