The refrigerant compressor (1) driven by motor compresses the gaseous refrigerant, which is thereby heated up and routed to the condenser (2).

The condenser's (2) surface withdraws the refrigerant's compression heat. When cooling down the refrigerant liquefies.

When flowing through the fluid reservoir (3) the refrigerant is purified of any chemicals and mechanical impurities and the water in the refrigerant is separated and collected.

The expansion valve (4) injects the cooled down and liquefied refrigerant in the evaporator (5), which is located in the fresh air flow. Here the refrigerant is vaporized. This vaporization process then withdraws heat from the blow-by fresh air which comes in from outside over the pipe and monolith systems with the result that it cools down.

The humidity carried along with it is converted to condensed water which is routed to the outside. The air is dried.

The refrigerant compressor (1) draws in the refrigerant which has turned gaseous on account of the heat absorption and compresses it again.

When the engine is running and the blower switched on, the passenger compartment can have cool air supplied to it by various outlet nozzles. The intensity of the cooling process depends on the previously set in-car temperature and the blower output.
