Operation

The refrigerant circuit of the parking cooler consists of four main
components:
 Compressor
The compressor draws in the R-134a refrigerant and compresses it. This
raises the pressure and therefore the temperature of the refrigerant.
 Condenser
The built-in condenser works like a cooler or heat exchanger. The air flow-
ing past absorbs the heat and the hot refrigerant gas cools down and
becomes liquid.
 Capillary tube
The capillary tube reduces the refrigerant from the higher condenser
pressure to the lower vaporisation pressure.
 Vaporiser
The vaporiser cools down the air flowing past and dehumidifies it. The
refrigerant absorbs the heat and vaporises. The cooled air is distributed
within the vehicle through an air outlet unit.
