Air conditioners are becoming increasingly distributed, and accordingly, questions about their maintenance and maintenance in working condition appear.
In order for it to work correctly, it is sometimes necessary to refill. Often it begins to work badly only because of the lack of Freon in it.
Owners of air conditioners are often wondering if the fueling of the system is possible, with their own hands, what tools are needed for this and how much freon is needed so that the air conditioner worked well.
It must be said that even if the air conditioner was installed absolutely correctly, over time, Freon will still flow out of it, so it is necessary to periodically refuel the refrigerant. If the air conditioner has become weaker to cool the air, it may not have enough freon in it.
How to fix split system air conditioner?
Before refueling, air conditioning must be properly prepared. Drain the system, it can be made nitrogen or freon. If the refrigerant is in the outer unit of the device, then Freon will be the best option.
It is important to see how sealed system, it needs to create pressure and the damaged area will be visible in ultraviolet rays.
Next you need to make vacuum, that is, remove the air from the pipeline. After that, you can begin the refueling of Freon, but it is important to correctly calculate its required amount.
There are three ways to refuel air conditioners. You can refuel by weight, pressure or with the help of viewing glass. If the refueling comes using the mass of the mass, then the freon is isolated, the contour vacuuming is also required.
The balloon is weighed on special scales to check how much refrigerant remains, then it goes to the desired level. If you want to make a pressure refueling, then you need to know the data about it, they are indicated by the manufacturer's manufacturer in the air conditioner passport, you will also need a gauge collector, the cylinder is supplied to the system in which the refrigerant is.

Refuel preferably in small parts. After receiving each part, you need to compare the testimony of the pressure gauge and the data in the passport. If they match, refueling can be completed.
It can be carried out with the help of viewing glass, it can be observed for freon with it. If there are bubbles in the device, it needs to be fed and do it until they disappear.
The fluid flow must be uniform. In order not to be excess Freon, it is necessary to refuel it with parts.
After completing the refueling, you need to check the device for tightness, to do this, turn it on to the minimum cooling mode, open both cranes and wait 15 minutes. If the taps begin to freeze, then freon is not enough if it does not happen, everything is fine.
Now buy split system is quite simple, while it is important to know that there are several types of freon. It is necessary to understand their differences and know which one is better.
- Freon R- 22 was used in the first air conditioners, it is not expensive, now they can be filled with almost any air conditioning, but it negatively affects the amount of ozone in the atmosphere.
- R410A Freon for the ozone layer is safe, it will increase the performance of the device.
- In Freon R407C there are refrigerants of three species, it is safe for the ozone layer, it is usually used in industrial split systems.
However, if there is a leak, then the light components will first disappear from it, which means that the device will need to be filled completely, it will be partially impossible, that is, the refrigerant will need to be removed and fed again.
If you carefully follow the air conditioning, then see that there is not enough freon in it, the bright indicator of this is the frost of the port of the device or its pipes.
If you have seen signs, you know how to make refueling and have the necessary equipment, you can start refrigeration. Pressure in different air conditioners is different, many factors affect it, it matters the street temperature and the brand of the air conditioner.

This information is specified in the instrument passport or on a metal shield that is fastened with an outdoor unit.
As a rule, if the installation of the air conditioner was correct, frequent refueling is not required if the device works fine, then freon, refilled at the manufacturer, is enough for several years.
You need to make refueling through the ports located on the outer block, if you have a multi split system, then there will be several such ports.
If you decide to fix the air conditioner using weights, it is better to completely remove freon and fill it again to not be mistaken, the number can be viewed in the passport or on Slight.
Add freon more than you need, it is useless, you will not have any savings or better cooling, on the contrary, it is better to not be discolored. If there is a lot of gas, it will not have time to move from the liquid to gas and back.
You can refuel the air conditioner at a temperature, it is somewhat harder, but it is quite possible. If freon in the system is sufficient, then the temperature in the fan located inside the fan should be 8 degrees with a discrepancy of 2 degrees, in some devices the minimum temperature is 5 degrees, it depends on the qualitative compressor of the device, all data is recorded in the passport.
The cleaning of the system is very important, if it is carried out in a timely manner, the device will work much longer. When cleaning and refueling the air conditioner, you must first always turn on the cooling mode, after which, run the device, only after that the device can be enabled on heating. If something is confused, the compressor will sing.
