Do-it-yourself car air conditioning
Content
The modern car air conditioner is the closest relative of the refrigerator. Gradually improving the air conditioner, a person came to the conclusion that a vapor compressor refrigeration unit is the best option for a car. Heat absorption in the air conditioner occurs due to the evaporation of freon (refrigerant), which moves under pressure through the system.
Why do you need to clean your car air conditioner?
The car air conditioner, regardless of types and designs, performs the task of adjusting the temperature, cleaning and circulating the air in the car. And like any intensively working device, it requires maintenance. Otherwise, it may happen that you have to change the air conditioner.
There are two good reasons to clean your air conditioner. The first, completely the same, according to which the car's cooling system is cleaned - cleaning the condenser (condenser) or in the "folk" language - the air conditioner radiator.
Its location is in front of the main engine cooling radiator. This creates certain difficulties with access for cleaning. It is advisable to clean the air conditioner condenser at the same time as cleaning the car's cooling system.
Features of cleaning the radiator of the air conditioner
Given its "fragility" and susceptibility to mechanical damage, cleaning must be carried out with the utmost care. It is advisable to clean the air conditioner radiator after removing the lining, i.e. grilles.
When cleaning the radiator of a car air conditioner, it is desirable to have a minimum water pressure, since a jet under high pressure can bend the ribs of the honeycombs. There are times when metal corroded by salt and reagents breaks through with pressure. But that's for the best. Then you will definitely change the radiator of the air conditioner to a new one, which means that its breakdown will not be unexpected.
Features of cleaning the air conditioner evaporator
Why do you need to clean the evaporator? The fact is that the surface of the evaporator is always wet, and as a result, after a certain period of time, the air begins to enter the cabin damp and musty. You understand that this is unhealthy (allergy), and again, you need to purchase a freshener.
To eliminate this phenomenon, or rather for prevention by cleaning the car air conditioner, there are special kits for cleaning the car air conditioner. This kit includes: cleaner in packs of 1 or 5 liters; reference book (instruction); aerosol cleaner.
Traditional air conditioner cleaning kit

To use this car air conditioner cleaning kit, you will need a special gun and compressed air (about 4-6 bar pressure). After cleaning the evaporator with a cleaner, start the engine again and dry the evaporator with hot air. Everything. You are ready to breathe fresh and clean air in the cabin again.
