Domestic Hot Water - Nibe F1226 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 a heat pump has COP of 5, this means that you only pay for a fifth of
your heating demand. This is the efficiency of the heat pump. This is
measured at different measurement values, e.g.: 0 / 35 where 0 stands
for the degrees in temperature of the incoming brine and 35 stands for
how many degrees the supply temperature is maintaining.
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.
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.
