Air central air - the general information and safety measures

The general information

Air central air (К/В) enters into a standard complete set of all models of a representation class, and also, as an additional complete set, can be established on any other models. The system allows to lower temperature of air submitted to salon, and also to make its drainage that appreciably raises comfort of stay in the car of the driver and passengers.

In a mode of cooling К/В the household refrigerator works by the same principle, as. The gaseous coolant is soaked up in the compressor working from a belt drive, then arrives in the condenser established before a radiator where gives the heat, passing in a liquid phase. Further, the liquid coolant through the broad valve arrives in the evaporator where from a liquid being under a high pressure turns to the rarefied gas. The given phase transition is accompanied by sharp temperature drop and, accordingly, evaporator cooling. Then the coolant comes back in the compressor and a cycle repeats.

Air blown through the evaporator is cooled and arrives in assemblage воздухораспределителя where by mixing with the hot air arriving from the heat exchanger of a heater, the temperature set for choice the operator is given to it. The received mix of air of the demanded temperature moves in car salon.

In case of need heating of air in salon the system works as a usual heater on models of a standard complete set (the System of heating/ventilation of salon - the general information see).

Management of system is carried out by electronics of the block of management BITRON which is carrying out the control over functioning of the electric fan (ов) of system of cooling, compressor K/V and built in in the panel of devices of a control lamp. In case of infringement of serviceability of functioning of system it is necessary to address in a special workshop or firm service-centre of company Citroyon.

Safety measures

At service of any components of a refrigerator path of a central air of air it is necessary to observe special safety measures. The same concerns the procedures connected with necessity рассоединения of lines of a refrigerator path.

As a working body in a central air of air of the car the liquid coolant (freon) can be used. Freon as chemical substance, it is potentially dangerous, that is why, to the reference with it can be admitted only the qualified expert. Coolant hit in contact to open sites of a skin can cause their deep обморожение. In itself freon is not poisonous, however at contact to open fire forms highly toxic gas, therefore inhalation of gaseous freon through the lighted cigarette can lead to the most serious consequences. Besides, freon hit in atmosphere causes a considerable damage to environment in view of irreversible destruction of an ozone layer.


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


It is necessary to charge any detachment of components and refrigerator lines of system of cooling to experts.
