Refrigerant circuit
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 tank water. The refrigerant R134a condenses
in the process.
R134a flows through the expansion valve in liquid state with decreasing
pressure. Then it is routed back to the evaporator.
