4.11. Air conditioning systems

GENERAL INFORMATION

On some models the air conditioning system is installed.

The system works as follows. The compressor compresses reagent and gives it to the condenser installed on a forward part of a radiator where reagent becomes liquid and reduces the temperature. Liquid reagent passes through the expansion valve to the evaporator where extends from liquid under high pressure to gas under low pressure. This expansion is followed by fall of temperature which cools the evaporator. Reagent comes back to the compressor and the cycle is repeated.

The air which passed through the evaporator gets to the distributor where mixes up with the hot air which passed through a heater therefore the set air temperature is reached.
Prevention

Work on the air conditioning system needs to be performed in specialized workshops. Air conditioning system is filled with special reagent (Freon) therefore it is impossible to depressurize system without special knowledge and the equipment.

The only action which can be executed independently on the air conditioning system is replacement of a driving compressor belt.
