3. Appliance description
The appliance is an air/water heat pump consisting of an
indoor unit and an outdoor unit. The appliance can be used
to heat a building and provide domestic hot water (DHW).
3.1 Functionality
An air/water heat pump extracts thermal energy from the
ambient air (low temperature) and transmits it together with
electrical drive energy in the form of useful heat (higher
temperature) to a heating and/or DHW circuit.
The heat pump consists of separated circuits linked togeth-
er via heat exchangers:
►
Heat source circuit (extracting heat)
►
Refrigerant circuit
►
Heat sink circuit (supply of heat to the central heating
and/or DHW)

3.2 Appliance components
3.2.1 Indoor unit
The indoor unit is intended to be installed only inside the
building. The indoor unit contains the compressor, which
in terms of sound technology is acoustically decoupled a
number of times from the casing. The casing is acoustically
optimised and allows particularly quiet operation.
