3.3 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.

TWH 200E TWH 300E TWH 300EH 3. Technical description

The refrigerant is depressurised in the thermostatic expansion valve and is cooled. The refrigerant can again extract the heat contained in the inlet air into the evaporator.
