Function
The refrigerant compressor (A9), which is driven by the motor, compresses the gaseous refrigerant which is heated up during the process, routed into the condenser (1) and thus cooled down. The refrigerant's compression heat is then withdrawn on the surface of the condenser (1). While cooling down, the refrigerant liquefies.
When it flows through the dryer cartridge (2) the refrigerant is dehydrated and cleaned of chemical and mechanical impurities. The liquid refrigerant flows through the expansion valve (3) into the evaporator (4), which is located in the air flow. Here the refrigerant is vaporized. This evaporation process extracts heat from the fresh air flowing past from outside via the tube and fin system, causing it to cool down.

The air humidity carried along is converted to condensed water, which escapes into the open. The air dries out.
The refrigerant compressor (A9) draws in the coolant which has turned gaseous through the collection of heat and compresses it again.
The refrigerant pressure sensor (B12) monitors the pressure of the refrigerant.
When the engine is running and the blower switched on, the interior can be supplied with cooled air through the various air outlets. Cooling intensity is dependent upon the preset in-car temperature and blower setting.
