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 example,
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 system.
This ensure the running of the heat pump and reduces the heat spikes that
could otherwise be heard from the climate system.
Calculated flow line temperature
The temperature 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.
