3.3 Function
Liquidrefrigerantisevaporated(evaporator).Theen-
ergy for this process is ambient heat coming from the
outside air. The gaseous refrigerant is compressed
(compressor),whichincreasesthepressureandthus
also the temperature. The gaseous refrigerant at high
temperatureisliqueed(condenser).
In the process, the high temperature is transferred to
the heating water and used in the heating circuit. The
liquid refrigerant at high pressure and high tempera-
tureisexpanded(expansionvalve).Thepressureand
temperature drop and the process restarts.
The heated heating water can be used for domestic hot
water or for heating the building. The temperatures re-
quired and the use are controlled by the heat pump con-
troller. Any required reheating, support in screed drying
or increase in the domestic hot water temperature can
be carried out using an electric heating element, which
is activated by the heat pump controller as required.
The vibration decoupling (accessory) for the hydraulic
system prevents structure-borne sound and vibrations
frombeingtransferredtothexedpipesandthustothe
building.
