Cleaning and refueling of the air conditioner

Air conditioning is a very useful device. Thanks to him in car trips, especially over long distances, become more comfortable and comfortable. Home appliances create coziness in hot and hot days. But like any other device, they require regular maintenance and repair. Periodically it is necessary to clean and refuel the air conditioner. This service is provided in specialized services. But if you have certain knowledge and skills, you can quickly perform all these procedures with your own hands.

Causes of odors from the air conditioner

The fact that the element needs to be cleaned can report a characteristic smell from the air ducts. There are several reasons for this phenomenon. More often the conditioner smells because of the formation on the evaporator of bacteria and mold. When the device cools the air, dust and dirt collect on the evaporator, which is located in the heater block, together with the air. Condensation also forms in the ducts. In addition to the air ducts, condensate appears both on the evaporator itself and also inside it. Dampness is an excellent medium for spreading various microorganisms, which are the sources of the smell.

Methods and types of cleaning work

The process of cleaning the air conditioner can be chemical or mechanical. The simplest chemical treatment involves the use of cleansing aerosol or foam preparations. It is necessary to take into account that the former are suitable only for disinfection. The cleaning itself should only be carried out using foam formulations. Mechanical treatment is used in cases when work with the help of chemical preparations did not bring the expected result. The mechanical method is much more complicated. It involves the dismantling of the evaporator. Also, if necessary, it is possible to refuel the air conditioner, since it is dismantled.

Chemical treatment and necessary preparations

There is a huge mass of producers whose means can defeat colonies of bacteria and mold in climatic systems and remove the smell. Most often these are aerosols for disinfection or foam for cleaning air conditioners with a tube of a certain length.
When the drugs are purchased, you can carry out a purification process. Treatment of the climatic system against bacteria is carried out as follows. If this car, the first thing to start the engine, then turn on the air conditioner and start the mode of recirculation of air to its full capacity. The aerosol can is installed near the passenger seat in front, where the air intake pipe is located. It remains only to start spraying the drug. All windows, as well as doors, must be closed. You also need to wait a certain time. Usually the waiting time is indicated on the package.

Then the air conditioner is turned off, and the room or room is thoroughly ventilated. In the case of foam, you need to remove the salon filter. In some models of cars, it is located just above the stove. Further on a can with foam put on a sealing tube. This is done to prevent foam from entering the evaporator. Then by this composition it is necessary to fill all air ducts. In addition, the foam can be introduced through the drainage holes. Then through the time, which is indicated in the instruction, run the air conditioner and allow him to work for about 10 minutes in various modes. After this, carefully ventilate the room or room.

Mechanical cleaning

This procedure will require the availability of a specific tool and materials. In the process, the refrigerant is discharged and the car's air conditioning refilled, each branch pipe and all washers are cleaned. First, dismantle the dashboard to get to the evaporator. Further, the refrigerant is pumped from the system. Sometimes you have to remove the stove to get to the air conditioning evaporator nozzles. Then detach each sensor, as well as a branch pipe, which goes to the radiator on the heat exchanger, and carefully remove this radiator. The element itself should be thoroughly washed with soapy water. Then it remains only to collect everything that is disassembled, and replace the oil in the compressor. You may need to refuel the air conditioner.

Why refuel the device?

This question is often asked by the inhabitants who are not familiar with the device of this technique. And right, why, because the manufacturer has already filled the unit? For new air conditioners, no additional refueling is needed, but eventually the refrigerant goes away. The cause of leaks may be incorrect installation, various mechanical damage to the nozzles or pipes. This is relevant not only for car air conditioners, but also for domestic split-systems. Often, due to malfunctions that lead to overheating of the compressor, antivibration elements and nozzles through which the refrigerant flows can collapse. The details rub against each other. Often they are wiped through, and then the special gas goes just into the air.

Consequences of Freon leakage

When the amount of refrigerant decreases or it goes away, there is no longer any difference between the outside and the inside air when the device is running. Without the filler, the unit will not be able to cool the air. Solve the problem by refueling the air conditioner. But first you should look for the cause of the leak. If you do not do this, after some time the coolant will go away again and the climate system will stop working.

Work with 410-m freon

Freon brand R410A consists of two components. Its physical characteristics are different from other refrigerants. The differences are in the boiling point. Therefore refueling the air conditioner with Freon 410 has its own peculiarities. Unlike R22 components, which can be used both in liquid and gaseous form, R410 is charged only in the liquid state. This is a guarantee of the ratio of the two components in the mixture in a one-to-one ratio. This is how the refrigerant will have better characteristics. Refilling the air conditioner with your own hands is done as follows. First of all, a special manometric collector is connected to the service port of the device. Then the refrigerant is completely discharged from the circuit. Then the circuit is evacuated and kept in this state for some time. After that, the device is charged by weight.

Refueling using freon-410

Refueling the air conditioner with freon-410 is not recommended. Manufacturers of climate control equipment advise if necessary to bleed all refrigerant completely and then re-inject a new one into the system. However, there are many disputes on this subject. Some companies involved in servicing climatic equipment, in order to minimize the cost of repairs, offer refueling. It is produced in the event that the leakage does not exceed 20 percent. The inhabitant of the norm does not know this. And it is determined by the pressure in the circuit and the environment. From this it follows that it is better to entrust the maintenance of air conditioners to professionals. Refueling the car air conditioner, if it has a 410th freon, should also be performed with the full output of the old freon.

Summary

Modern climate technology can be serviced independently. However, it is necessary to take into account that not all the issues can be solved with our own hands. For example, it is possible to clean and refill the air conditioner if it is charged with a suitable refrigerant. But to perform more serious tasks should only professionals.
