Domestic Hot Water - Nibe F1245 User Manual

Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled and
becomes a liquid) and releases heat energy to the house heating and hot
water systems.
Convector
Works in the same way as a radiator, but with the difference that the air is
blown out. This means that the convector can be used to heat or cool the
accommodation.
COP
If it is stated that a heat pump has COP 5, this means, in principle that if you
insert 10 pence, you will get 50 pence worth of heat. It is the efficiency of
the heat pump. This is measured at different measurement values, e.g.: 0/35
where 0 stands for how many degrees the temperature of the incoming brine
is and 35 for how many degrees the supply temperature is.
Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low or
if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of a
disturbance in comfort.
In most cases, the heat pump notes operational interference and indicates
this with alarms and shows instructions in the display.

Domestic hot water

The water one showers in for example.
DUT, 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".
