Hello, dear motorists! Let's try to remember, don't we fill the refrigerator (at home) with freon every year? Of course not. The question arises - why is it recommended to fill the car's air conditioner at least once a year? Don't car services use us for filling and servicing air conditioners?
Calm down. It doesn't work. The reason is simple and understandable to everyone, if we know it. The thing is that comparing the work of a refrigerator with the work of an air conditioner is, at the very least, incorrect. The refrigerator stands quietly at home, without dynamic load, in the heat, when at that time, the air conditioner...
When and whatbecause the air conditioner needs to be refilled
In principle, a car's air conditioner is just as sensitive as an air conditioner in your home or a refrigerator in your kitchen.
It is surrounded by: a. aggressive environment in which various technical fluids evaporate when the engine is running
b. constant temperature fluctuations c. operated under conditions of constant vibration.
This affects the air conditioner equipment and connections accordingly. Finally, they are threaded, unlike welded ones, as in refrigerators. Under the influence of the specified factors, over time, the tightness of the system changes and obvious leakage (evaporation) of freon begins.
Air conditioner refilling is not done on a strictly defined schedule, but manufacturers and experts recommend practicing refilling regularly, even if there are no visible defects.
Typically, for a new car, checking and refilling the air conditioner is recommended once every 2-3 years. For cars that are 6-10 years old, refilling is required once a year.
We will repeat, this is in the absence of a specific malfunction, due to spontaneous evaporation of freon. But, as we know, there are also malfunctions of the air conditioning system, the result of which is a freon leak. In such a case, we unequivocally recommend repairing and filling the air conditioning system.
Typical air conditioner malfunctions
The most common faults that cause freon leakage (evaporation) are:
- spontaneous loss of sealing properties or their mechanical damage;
- The most common causes of failure are condenser (radiator) and tube corrosion.As a result of exposure to an aggressive environment, they become out of alignment, which affects the leakage (evaporation) of chladogen.
- Rubber parts (gaskets, hoses) located under the hood (lid) gradually dry out and crack due to constant temperature changes. In addition, the gaskets lose their elasticity. As a result, the car's air conditioning system becomes leaky.
It is for this reason that filling the car's air conditioner begins with a thorough diagnosis of the entire system. There is no need to reinvent the wheel and experiment with a relatively inexpensive device. That is, we would not suggest filling the air conditioner yourself. Why do you need "Kulybino's laurels", for your own money? J
In a specialized service center, which has all the equipment for filling car air conditioners, qualified craftsmen will do it for you. They will check and fill with the required amount of freon. If necessary, repairs will be made or faulty parts will be replaced.
How to refill the conditioner
Car air conditioner filling equipment is quite diverse and complex in design. All necessary operations are performed in automatic or semi-automatic mode.
Before starting an air conditioner upgrade, find out how the freon will be pumped out of the air conditioning system and whether it will continue to be used in the cooling system.
This will reduce your financial costs. Yes, by the way, if you have already come for car air conditioning service, ask them to perform antibacterial cleaning.
And so. What does filling a car's air conditioner involve?
- removing freon from the system;
- creating a vacuum in the system and performing diagnostics for leaks. Moisture, air, mechanical impurities, etc. are removed from the system.
- injection of additives and lubricant into the system. (Lubricant is added to the system, which is also lost along with freon during operation.
- testing the system's operating pressure and filling the conditioning circuit.
In the process of filling a car air conditioner, the rate set by the car manufacturer is used due to the amount of freon.
We can say that's it. You are ready to ride comfortably in hot and humid weather.
