Air conditioning system

The air conditioning system consists of a condenser located in front of the radiator, an evaporator located near the heater, a compressor mounted on the engine and a dehydrator. The heater fan drives warm air into the car interior through the evaporator, cools it to the required temperature.

Attention. The air conditioning system is under pressure, so no connections in the air conditioning system should be loosened until the pressure is relieved.

Warning

The air conditioning system must only be serviced by trained technicians trained in safe working practices. using proper equipment, in compliance with depressurization rules. 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. Early models used R12, later R134A. 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 volume, because. Reagent vapors may 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 Call a doctor or health care provider immediately. Self-medication is not allowed.
• it is impossible to influence the reagents of the air conditioning system with an open flame, because. in this case, poisonous gas is formed and in some cases an explosion can occur.
• Discharge the air conditioning system only into suitable containers, as otherwise, serious damage will be done to the environment.
• Reagent R134A must not be mixed with Reagent R12, as in the air conditioning system, different types of compounds are used for different reagents.
• in the event of any disconnection of the air conditioning system, refueling and putting the system in order must be carried out at a service station.
• if it is necessary to perform welding, soldering or other work associated with high temperatures near the air conditioning system, it must first be discharged.
• Cleaning the condenser or evaporator with steam is not permitted. Use only cold water or compressed air.
