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.
Heating medium side
Pipes to the house’s climate system make up the heating medium side.
Mixing valve
A valve that mixes the cold water with the hot water leaving the heater.
Outside sensor
A sensor that is located outdoors. This sensor tells the heat pump how hot
it is outdoors.
Pressostat
Pressure switch that triggers an alarm and/or stops the compressor if non-
permitted pressures occur in the system. A high pressure pressostat trips
if the condensing pressure is too great. A low pressure pressostat trips if
the evaporation pressure is too low.
Radiator
Another word for heating element. They must be filled with water in order
to be used with F370.
