4.3 Operating principle
The thermodynamic DHW tank uses unheated ambient air or outside
air to prepare DHW.
The refrigerant circuit is a closed circuit in which the R-134a
refrigerant plays the role of an energy carrier.
The heat from the intake air is transferred to the refrigerant in the
finned heat exchanger at a low evaporation temperature.
The refrigerant is sucked in by a compressor in vapour form, which
raises it to a higher pressure and temperature and sends it to the
condenser. In the condenser, the heat extracted in the evaporator and
some of the energy absorbed by the compressor are released into
the water.
