3.5 Function
Liquid refrigerant is evaporated (evaporator), the
energy for this process is environmental heat and
comes from the outside air. The gaseous refrigerant is
compressed (compressor), this causes the pressure
to rise and therefore the temperature too. The
(condenser).
The high temperature is hereby discharged to the
heating water and is used in the heating circuit.
The liquid refrigerant at a high pressure and high
temperature is depressurised (expansion valve).
The pressure and temperature drop and the process
begins again.
The heated heating water can be used for the domestic
hot water charging or for the building heating. The
temperatures required and use are controlled by the
heat pump controller. Reheating, drying out screed or
increasing the domestic hot water temperature can be
carried out by using an electric heating element, which
is activated by the heat pump controller as and when
necessary.
The vibration decouplers (accessories) for the
hydraulics
prevent
structure-borne
and therefore into the building.
