How to fill the refrigerator with freon at home

Refilling the refrigerator with freon with your own hands does not constitute a major difficulty. To do this, follow the simple instructions to avoid further leaks.

There are different situations when you may need to replace the refrigerant in the refrigerator yourself. Most often the refrigerator is filled with freon, this gas is best suited for this. To figure out how to fill the refrigerator with freon yourself, you need to understand the device and the scheme of its operation. First you need to understand what freon is and why this gas is used in the cooling system of the refrigeration unit.

How does freon work in refrigerators?

Freon is used as a refrigerant, it circulates in a closed circuit between the compressor and the condenser. Freon is liquefied in the condenser, and getting into the evaporator takes heat energy into itself. Thus, if refrigerant leakage is allowed, cooling is reduced or ceases completely. If the temperature in your refrigerator has ceased to correspond to the established parameters, one of the primary reasons may be freon leakage.

Freon is chosen by chance, this gas has no color and smell, and also does not cause any harm to the human body. Its leakage will not entail any consequences, which makes it an excellent option for use in the refrigerator, where our food is stored. Gas can be used for a very long time, it does not lose its properties. Freon replacement is most often caused by its leakage.

When refilling the refrigerator with

freon is necessary Freon leakage cannot be traced by any physical signs, as it has no color or smell. The surest way to determine if you need to refill freon at the moment is to check the temperature of the refrigerator. The greater the difference between normal and actual temperature is observed, the greater the freon leak occurred at the moment.

Mechanical damage to individual parts may be the cause of the leaks; before they are repaired, the replacement of the refrigerant will not make sense, so the likelihood of re-leakage will be high. The main causes of freon losses are:

• corrosion of tubes and metal elements of the capacitor;
• breakage and mechanical damage to the tubes;
• low quality tubes containing cracks of invisible eye sizes;
• incorrect connection of tubes.

Only after fixing all the shortcomings of the refrigerator system, you can begin to perform refueling. For most of the parts need to be replaced, different tubes to repair separately does not make sense.

How to fill a freon refrigerator at home

Before you start filling your own freon, remember the safety requirements, the system is under pressure, which is fraught with dangerous situations. We determine the brand of refrigerant( freon), it is not difficult to do this, all the necessary information is always indicated on the compressor, you just have to examine it more carefully. It is also necessary to know how much freon should be used; this can also be learned from the information on the compressor housing.

For filling the refrigerator with freon do-it-yourself you should prepare everything you need in advance - a cylinder with freon, hoses with valves, a special collector. First you need to pick up the blue hose to the pipe for refueling, and put both valves in the closed position. Next, you need to look at the pressure, the fitting with which the red hose must be coupled is soldered to the injection line. Shut off when the pressure reaches the half-atmosphere value, then start the compressor for 30 seconds.

We connect a yellow hose to the vacuum pump, after opening the blue valve, the pump is turned on for 10 minutes, and then the hose is connected to the refrigerant cylinder. Next, it starts charging the refrigerator with gas, you need to freon filled the entire compressor. All movements to close the valves should be smooth and unhurried, the replacement of the cooling gas does not tolerate haste. Together with the gradual closure of the yellow valve opens blue.

If you consider that replacing the refrigerant with your own hands was successful, you need to start the compressor of the refrigerator. The system pressure is checked again. If the normal value corresponds to how much the instrument indicates, all used tubes should be clamped, disconnected and soldered. The reliability of the soldering depends on the absence of future refrigerant leaks.
