Operating principle
4.2.1
Thermodynamic water heater
The thermodynamic water heater uses the outside air to produce domestic
hot water.
The refrigerant circuit is a closed circuit in which the R134a 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 drawn in in vapour form by a compressor, 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.
The refrigerant is depressurised in the expansion valve and then cooled.
The refrigerant fluid can again extract the heat contained in the intake air
from the evaporator.
