Heat exchanger
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers are evaporators
and condensers.
Heat factor
Measurement of how much heat energy the heat pump gives off in relation
to the electric energy it needs to operate. Another term for this is COP.
Heating curve
The heating curve determines which heat the heat pump is to produce
depending on the temperature outdoors. If a high value is selected, this
tells the heat pump that it must produce a lot of heat when it is cold out-
doors in order to achieve a warm indoor temperature.
Heating medium
Hot liquid, usually normal water, which is sent from the heat pump to the
house climate system and makes the accommodation warm. The heating
medium also heats the hot water through the double jacketed tank or coil
tank.
Heating medium side
Pipes to the house’s climate system and condenser make up the heating
medium side.
Hot water heater
Container where domestic water is heated. Is located somewhere outside
the heat pump.
Level monitor
Accessory that senses the level in the level vessel and gives an alarm if it
becomes too low.
Level vessel
Partially transparent vessel with brine with the task of equalising the
pressure in the brine system. When the temperature of the brine increases
or decreases, the pressure in the system changes and the level in the level
vessel also changes.
Mixing valve
A valve that mixes the cold water with the hot water leaving the heater.
