DOT, DIMENSIONED OUTDOOR TEMPERATURE
The dimensioned outdoor temperature differs depending on where you
live. The lower the dimensioned outdoor temperature, the lower the
value should be selected on "selecting a heat curve".
EFFICIENCY
A measurement of how effective the heat pump is. The higher the value
is the better it is.
ELECTRICAL ADDITION
This is electricity that, for example, an immersion heater uses as addition
during the coldest days of the year to cover the heating demand that the
heat pump cannot manage.
EMERGENCY MODE
A mode that can be selected using the switch in the event of a fault,
which means that the compressor stops. When the heat pump is in
emergency mode, the building and/or hot water is heated using an im-
mersion heater.
EVAPORATOR
Heat exchanger where the refrigerant evaporates by retrieving heat en-
ergy from the brine which then cools.
EXPANSION VALVE
Valve that reduces the pressure of the refrigerant, whereupon the tem-
perature of the refrigerant drops.
EXPANSION VESSEL
Vessel with brine or heating medium fluid with the task of equalising the
pressure in the brine or heating medium system.
FAN CONVECTORS
A type of convector, but with auxiliary fan that blows hot or cold air into
the accommodation.
FILTERING TIME
Indicates the time the average outdoor temperature is calculated on.
