There are several kilograms of freon in the outdoor module of the air conditioner during installation. It is enough for 2 - 4 years of effective work. However, sooner or later you have to refuel the air conditioner. And many owners would like to fill the air conditioner at home with their own hands.
Refueling the air conditioner at home
The longer the freon line, the greater the loss of refrigerant will be. For a year, it can evaporate from 8% with a very high-quality installation and flaring of joints. But most of the refrigerant is lost during the dismantling or repair of the outdoor unit. You can fill the air conditioner at home by studying all the subtleties of the process.
The most important thing is to add as much refrigerant as required.
An excess of it is as undesirable as a lack.
There are several methods most affordable for refueling:
- overheating of the compressor;
- condenser overcooling;
- by mass.
Step-by-step instructions for refueling the air conditioner
Watch the video of refueling the air conditioner on our website:
- Close the three-way valve by turning it clockwise;
- Connect a manifold (low pressure outlet);
- Open the valve;
- Connect the container with the refrigerant installed on the balance to the collector;
- Run the air conditioner in the cold;
- Open the manifold valve and fill in refrigerant in batches, constantly observing the weight;
- As soon as the required volume is filled, turn off the tap.
The pressure in a fully charged system averages 15 kg per cubic centimeter. If the air conditioner has been fully charged, as in the video below, the system cannot be started immediately.
It takes time for the refrigerant to be evenly distributed along the line.
Where to refuel the air conditioner
The climate system began to cool poorly, frost freezes on the fittings of the outdoor unit. This means it's time to prime the air conditioner. Where to do it?
Refueling is carried out directly at the installation site, that is, you do not need to remove the unit. You can call the masters to your home or office, or try to refuel the air conditioner yourself. Where can you get the necessary tool and freon itself? Search engines will suggest thousands of suggestions.
You need to buy exactly the refrigerant with which the air conditioner is already charged.
Its type is indicated in the instructions. For refueling, a can of up to 800 grams is sufficient. You need to purchase a special piercing for him. If the air conditioner is charged from scratch, a large amount of refrigerant will be required.
The entire Internet is crammed with nonsense about 8% freon leakage and about refueling 2 times a year. I have 2 kondeya at home and 6 in the garage (car service). For various periods of their operation, I have never refueled! So he installed the home air conditioners himself, without vacuuming (blowing), reinstalled when moving. 10 years of service without problems and refueling! Garage - from 3 to 6 years without refueling, he took everything used for a penny.
I agree, if there is a leak, the installer has crooked hands, a possible problem, which for some reason is kept quiet, is Chinese freon, which after a few years loses its properties
