2 Intended use of the heat
pump
2.1 Area of application
The air-to-water heat pump is intended exclusively for heating
or, depending on the device, also cooling heating water. It can
be used in new or existing heating systems.
The heat pump is suitable for mono energy and bivalent opera-
tion.
During continuous operation, proper defrosting of the evapora-
tor must be guaranteed by maintaining a heating water return
temperature of more than 18 °C.
The heat pump is not designed for the increased heat con-
sumption required when a building is being dried out. For this
reason, the additional heat consumption should be met using
special devices provided by the customer. For drying out a
building in autumn or winter, it is advisable to install a second
heat generator (e.g. an electric heating element available as an
accessory).
NOTE
ººººº
The device is not suitable for operation with a frequency
converter.
2.2 Operating principle
Heating
Surrounding air is drawn in by the fan and fed through the evap-
orator (heat exchanger). The evaporator cools the air, i.e. ex-
tracts heat from it. This extracted heat is then transferred to the
working medium (refrigerant) in the evaporator.
The heat is brought to a higher temperature level by increasing
its pressure with the aid of an electrically driven compressor. It
is then transferred to the heating water via the liquefier (heat
exchanger).
Electrical energy is used to raise the temperature of the heat
from the environment to a higher level. Because the energy ex-
tracted from the air is transferred to the heating water, this type
of device is referred to as an air-to-water heat pump.
The main components of an air-to-water heat pump are the
evaporator, fan and expansion valve, as well as the low-noise
compressor, liquefier and the electrical control system.
At low ambient temperatures, humidity accumulates on the
evaporator in the form of frost, reducing the transfer of heat.
Uneven accumulation during this process does not indicate a
fault. The evaporator is defrosted automatically by the heat
pump as required. Under certain atmospheric conditions,
steam may be emitted from the air outlet.
Cooling (device-dependent)
The functions of the evaporator and the liquefier are reversed in
the “Cooling” operating mode.
The heating water transfers its heat to the refrigerant via the liq-
uefier, which is now functioning as an evaporator. The refriger-
ant is brought to a higher temperature level using the compres-
sor. Heat is transferred to the surrounding air via the liquefier
(which, in heating operation, functions as an evaporator).
