System theory
The refrigerant circuit is a closed system in which the
refrigerant R134a circulates as a heat transfer medium.
The evaporator transfers the heat from the air to the refrigerant
circuit, and the refrigerant evaporates into a gas.
The compressor compresses the refrigerant R134a, thus
increasing its temperature.
Then the heat is transferred via a heat exchanger, also referred
to as a condenser, to the storage water tank. The refrigerant
R134a condenses in the process.
R134a flows through the expansion valve in a liquid state with
decreasing pressure. Then it is routed back to the evaporator.
Brief overview of modes
• Heat pump mode: only the economical heat pump cycle
is used; if the air temperature goes beyond the nominal
range (3 °C - 40 °C) the appliance automatically turns
off.
• Combi mode: the heat pump cycle is used under the
nominal range for the air temperature (3 °C - 40 °C); if
the air temperature goes out of this interval, the
appliance automatically switches to the electrical
heating element; this is the factory pre-selected mode.
