Refrigerant
Substance that circulates around a closed circuit in the heat pump and
that, through pressure changes, evaporates and condenses. During evap-
oration, the refrigerant absorbs heating energy and when condensing
gives off heating energy.
Return pipe
The line in which the water is transported back to the heat pump from
the house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the heat pump after releasing
the heat energy to the radiators/heating coils.
Room sensor
A sensor that is located indoors. This sensor tells the heat pump how hot
it is indoors.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shunt
A valve that mixes the hot water with a small amount of slightly cooler
water. There is a shunt in the heat pump that mixes the supply water with
the return line water so that the heating system reaches the correct tem-
perature.
Supply temperature
The temperature of the heated water that the heat pump sends out to
the heating system. The colder the outdoor temperature, the higher the
supply line temperature becomes.
Water heater
Container where domestic water is heated. Is located inside the heat pump,
but an extra hot water heater can be installed in the event of large hot
water requirements.
