The refrigerant compressor (A9) which is driven by the engine compresses the refrigerant vapor, which heats up in the process. The refrigerant is conducted to the condenser (2).
The surface of the condenser (2) is used to withdraw the compression heat from the refrigerant. The refrigerant liquefies during cooling. As it flows through the fluid reservoir (3) the refrigerant is cleaned of chemical and mechanical impurities. The cooled and liquefied refrigerant flows through the expansion valve (4) into the evaporator (5), which is located in the fresh-air flow. The refrigerant is then vaporized. Through this evaporation process heat is extracted from the fresh air flowing past from outside over the tube and fin system so that air cools down.
The air humidity carried along is converted to condensed water, which is routed to the outside. The air is thus dried. The refrigerant compressor (A9) draws in the refrigerant which has turned gaseous again through the collection of heat and compresses it.
When the engine is running and the blower motor is switched on, the interior can be supplied with cooled air through the various air outlets. The degree of cooling intensity is dependent upon the previously set interior temperature and the output of the blower motor.
