3.3 How it works
Liquid (primary) refrigerant is evaporated (evaporator).
The energy for this process is environmental heat and
comes from the outside air. The gaseous refrigerant is
compressed (compressor), which increases the pres-
sure and therefore also the temperature. The gase-
ous refrigerant with high temperature is liquefied (con-
denser).
The high temperature is discharged to the heating wa-
ter and used in the heating circuit. The high-pressure,
high-temperature liquid refrigerant expands (expan-
sion valve). The pressure and temperature drop, and
the process begins again.
Once heated, the heating water can be used for the
domestic hot water supply or for heating the building.
The temperatures required and the use are controlled
by the heat pump controller. Reheating, drying out
screed or increasing the domestic hot water temper-
ature can be carried out using an electric heating el-
ement, which is activated by the heat pump controller
as and when necessary.
The vibration isolators (accessories) for the hydraulics
prevent structure-borne sound and vibrations from be-
ing transmitted to the fixed pipes and therefore to the
building.
