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.
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.: 7 / 45 where 7 stands
for the outdoor temperature and where 45 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 malfunctions and indicates this with
alarms in the display.
Domestic hot water
The water one showers in for example.
Double-jacketed tank
A heater with domestic hot water (tap water) is surrounded by an outer
vessel with boiler water (to the house radiators/elements). The heat pump
heats the boiler water, which in addition to going out to the all the house
radiators/elements, heats the domestic hot water in the inner vessel.
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.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
