Attention! The air conditioning system is under pressure, so no connections in the air conditioning system should be loosened until the pressure is relieved.
On some models, an air conditioning system is installed. The system works as follows. The compressor compresses the reactant and feeds it to the condenser where the reactant becomes liquid and reduces its temperature. The liquid reactant passes through the expansion valve to the evaporator where it expands from a high pressure liquid to a low pressure gas. This expansion is accompanied by a decrease in temperature, which cools the evaporator. The reagent returns to the compressor and the cycle repeats. The air that has passed through the evaporator enters the distributor, where it mixes with the hot air that has passed through the heater, as a result of which the set air temperature is reached.
The only thing you can do yourself on an air conditioning system is to replace the compressor drive belt.
Attention! The air conditioning system must only be serviced by trained technicians who are trained in safe work practices, using the proper equipment, in compliance with depressurization procedures, familiar with the collection and storage of automotive refrigerant.
When working on the air conditioning system, the following requirements must be observed:
- the air conditioning system is filled with reagents, which are very dangerous substances. When working with reagents, they should not get on the upholstery, clothing, eyes and body. Reagents that come into contact with the body will cause severe frostbite. It is also impossible to carry out work with reagents in a closed space, since reagent vapors can cause suffocation. Reagents are heavier than air, therefore they are collected in the lower parts of the room or in the inspection hole;
- wear protective goggles when working near the air conditioning system;
- If refrigerant comes into contact with skin or eyes, do not rub the affected area. Rinse immediately with cold water for at least 15 minutes. Contact a doctor or health facility immediately. Self-medication is not allowed;
- it is impossible to influence the reagents of the air conditioning system with an open flame, because this produces a poisonous gas, and in some cases an explosion may occur;
- discharge the air conditioning system only into appropriate containers, as otherwise serious damage will be done to the environment;
- in the event of any disconnection of the air conditioning system, refueling and putting the system in order must be carried out at the maintenance station;
- if it is necessary to perform welding, soldering or other work related to high temperatures near the air conditioning system, it must first be discharged;
- Cleaning the condenser or evaporator with steam is not allowed, only cold water or compressed air should be used.
