In the outdoor module of the air conditioner during installation there are several kilograms of freon. It is enough for 2 to 4 years of effective work. However, sooner or later it is necessary to refuel the air conditioner. And many owners would like to make their own air conditioning at home.
Air conditioning at home
The longer the freon line, the greater the loss of refrigerant will be. Over a year, it can evaporate from 8% with very high-quality installation and flaring of joints. But most of the refrigerant is lost during the dismantling or repair of the outdoor unit. At home, you can refuel the air conditioner by studying all the details of the process.
The most important thing is to fill the refrigerant as much as required.
An excess of it is also undesirable, as well as a disadvantage.
There are several methods available for refueling:
- overheating of the compressor;
- condenser overcooling;
- by weight.
Step-by-step instructions for refueling the air conditioner
Video of refueling the air conditioner, see our website:
- Close the three-way valve by turning it clockwise;
- Connect pressure gauge manifold (low pressure output);
- Open valve;
- Attach a refrigerant tank mounted on the balance to the collector;
- Run the air conditioner in the cold;
- Open the manifold valve and fill with refrigerant in batches, constantly monitoring 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 was completely refilled, as in the video that you see below, the system cannot be started immediately.
It takes time for the refrigerant to be evenly distributed along the track.
Where to refill air conditioning
The climate system began to cool poorly, frost on the fittings of the outdoor unit freezes. This means it's time to refuel 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 craftsmen to your home or office or try to refuel the air conditioner yourself. Where to get the necessary tool and freon itself? Search engines will suggest thousands of offers.
You need to buy exactly the refrigerant with which the air conditioner is already charged.
Its type is indicated in the instructions. A barrel weighing up to 800 grams is enough for refueling. To him you need to purchase a special puncture. If the air conditioner is charged from scratch, a large amount of refrigerant will be required.
