4.11. Air central airs

On some models air central air is established.

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

Air which has passed through the evaporator, gets to the distributor where mixes up with the hot air which has passed through a heater therefore the set temperature of air is reached.
The prevention

Work on air central air is necessary for making in specialised workshops. The central air is filled by a special reagent (Freon), therefore it is impossible to depressurize system without special knowledge and the equipment.

Unique action which can be executed independently on air central air, is replacement приводного a compressor belt.
