Additional heat:
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for ex-
ample, immersion heater, electric heater, solar power system,
gas/oil/pellet/wood burner or district heating.
Buffer vessel
A buffer vessel increases the system volume and removes the unwanted
temperature variations that can otherwise be sent out on the climate sys-
tem. This ensure the running of the heat pump and r educes the heat spik es
that could otherwise be heard from the climate system.
Calculated flow line temperature
The temper atur e that the indoor module calculates that the heating system
requires for an optimum accommodation temperature. The colder the
outdoor temperature, the higher the calculated supply temperature.
Charge pump
See "Circulation pump".
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
Climate systems can also be called heating systems. The building is heated
using radiators, under floor coils or convector fans.
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating and
hot water systems.
Convector
Works in the same way as a radiator, but with the difference that the air
is blown out.
