The general description and precautions - air central air

Air central air allows to lower quickly temperature, and also humidity of air arriving in salon.
The cooling part of system works like a household refrigerator. Coolant steams arrive in the compressor resulted by a belt and are forced in the condenser established on the forward party of a radiator where they cool down and pass in a liquid state. The liquid passes through a gas reducer to the evaporator where it turns from a liquid under a high pressure to gas of low pressure. This change of a condition is accompanied by the absorption of energy leading to fall of temperature in the evaporator. The coolant comes back in the compressor, and the cycle is started over again.
Air banished through the evaporator, passes in the block воздухораспределителя where it mixes up with the hot air which has left the heat exchanger of a heater, the desirable temperature in car salon thus is reached.
The heating up part of system works the same as on models without air conditioner (address to Section the General description of a heater).
The system copes with the help of electronics. Concerning any problems connected with given system, address on HUNDRED Renault.

Precautions

If for any reason the system has to be depressurized, charge this work to the expert.

The cooling part of system can contain a liquid coolant and consequently for separation of components of system the special equipment is required.

The coolant is potentially dangerous, if it gets on a skin, it will cause serious обморожение. The In itself coolant is not poisonous, but at its hit in an open flame (or at a present of the lighted cigarette) highly toxic gas is formed.
Do not include air central air if it is known that in it the coolant as it will lead to compressor damage does not suffice.
