pressure. The liquid is pressed through a capillary tube where the resulting pressure drop ensures that the refrigerant
evaporates at a defined temperature. The liquid refrigerant which is under low pressure is led into the heat
exchanger, where it expands. The cold resulting from the expansion serves to cool down the compressed air
in the heat exchanger. During this process, the refrigerant evaporates. The low-pressure gas is resupplied to
the compressor, where it is compressed again. It then re-enters the cycle. In phases of a reduced compressed-
air load, the excess refrigerant is resupplied automatically to the compressor via the hot gas bypass valve.
