The air conditioning system - the general information and precautionary measures

General information

The air conditioning system (K/V) is included in a basic equipment of all models of a representative class, and also, as an additional complete set, can be installed on any other models. The system allows to reduce temperature of the air given to salon, and also to make its drainage that considerably increases comfort of stay in the car of the driver and passengers.

The household refrigerator works in the cooling mode To/in by the same principle, as. Gaseous coolant is soaked up in the compressor working from the belt drive, then comes to the condenser installed before a radiator where gives the heat, passing into a liquid phase. Further, liquid coolant via the broad valve comes to the evaporator where from the liquid which is under high pressure turns into the rarefied gas. This phase transition is followed by sharp temperature drop and, respectively, cooling of the evaporator. Then coolant comes back to the compressor and the cycle is repeated.

The air blown via the evaporator is cooled and comes to assembly of the air distributor where by mixing with the hot air arriving from the heater heat exchanger it is given temperature set at the choice of the operator. The received mix of air of the required temperature moves in interior of the car.

In case of need heating of air in salon the system works as a usual heater at models of a basic equipment (see System of heating/ventilation of salon - the general information).

Control of system is exercised of electronics of the BITRON control unit exercising control over functioning of the electric fan(s) of the cooling system, the K/V compressor and the control lamp which is built in in the dashboard. In case of violation of serviceability of functioning of system it is necessary to address in a special workshop or company service center of the Citroyon company.

Precautionary measures

At service of any components of a refrigerator path of the air conditioning system it is necessary to observe special precautionary measures. The same concerns the procedures connected with need of a rassoyedineniye of lines of a refrigerator path.

As a working body in the air conditioning system of the car liquid coolant (freon) can be used. Freon as chemical, is potentially dangerous, and therefore, only the qualified specialist can be allowed to the treatment of him. Hit of coolant in contact with open sites of skin can cause their deep frostbite. Freon in itself is not poisonous, however at contact with naked flame forms highly toxic gas therefore inhalation of gaseous freon through the lit cigarette can lead to the most serious consequences. Besides, hit of freon in the atmosphere causes significant damage to the environment in view of irreversible destruction of an ozone layer.

If there are suspicions on decrease in level of coolant of the air conditioning system, it is necessary to stop its further use as it is fraught with failure of the compressor.

Any detachment of components and refrigerator lines of the cooling system should be charged to experts.
