The list of available material (separate document) must be checked in order to choose the adequate material for
repairs in the refrigeration circuit.
3.2 Components System
Model + 5ºC to +35ºC
The refrigerant must enter in the evaporator, in the liquid state, and then, by vaporizing due to heat absorption from
the surrounded air, the refrigerant leaves the evaporator in the vapour state and during the refrigerant
condensation, there is a heat generation, which will be transferred, in this case, to the domestic water, that flows in
the condenser.
Pict.20 – General components overview in the module +5ºC / + 35ºC
As the temperature of the available water is always higher than the one from boiling refrigerant in the evaporator,
the refrigerant in the vapour state needs to be pressurized till its condensing temperature is above the temperature
of the water available for the condensing process – that is why a compressor is needed.
