EXPANSION VALVE
Valve that reduces the pressure of the refrigerant, whereupon the tem-
perature of the refrigerant drops.
EXPANSION VESSEL
Vessel with fluid with the task of equalising the pressure in the system.
EXTRACT AIR
The air that the heat pump has retrieved heat from and which has
therefore been cooled. This air is blown out of the building.
FILTERING TIME
Indicates the time the average outdoor temperature is calculated on.
FLOW PIPE
The line in which the heated water is transported from the heat pump
out to the house heating system (radiators/heating coils).
HEAT EXCHANGER
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers include evapor-
ators and condensers.
HEAT FACTOR
Measurement of how much heat energy the heat pump gives off in re-
lation 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
outdoors 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.
