FLOW PIPE
The line in which the heated water is transported from the heat pump
out to the house heating system (radiators/heating coils).
FREE COOLING
The cold brine from the collector/borehole is used to cool the accommod-
ation.
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 SIDE
Pipes to the house’s climate system and condenser make up the heating
medium side.
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 in-
creases 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.
