2.2Operating Principle

Heating

Surrounding air is drawn in by the ventilator and fed via the evap- orator (heat exchanger). The evaporator cools the air, i.e. it ex- tracts heat from it. This extracted heat is then transferred to the working medium (refrigerant) in the evaporator.

The heat is “pumped” 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 using the liquifier (heat ex- changer).

Domestic water can be prepared simultaneously, or separately, via the desuperheater connected in series.

Electrical energy is used to raise the temperature of the heat in the environment to a higher level. Because the energy extracted from the air is transferred to the heating water, this type of device is called an air-to-water heat pump.

The air-to-water heat pump consists of the main components evaporator, ventilator and expansion valve, as well as the low- noise compressor, desuperheater, liquifier and electrical control system.

At low ambient temperatures, humidity accumulates on the evap- orator in the form of frost reducing the transfer of heat. The evap- orator is defrosted automatically by the heat pump as required. Steam may be emitted from the air outlet depending on the at- mospheric conditions.

Cooling

The functions of the evaporator and the liquifier are reversed in the “Cooling” operating mode.

The heating water transfers its heat to the refrigerant via the liq- uifier which is now functioning as an evaporator. The refrigerant is pumped to a higher temperature level using the compressor. Heat is passed on to the surrounding air via the liquifier (function- ing as an evaporator in heating operation).

The waste heat can also be used for hot water consumers, such as domestic hot water, swimming pool or bathroom heating, via the additional heat exchanger.
