Currently, there are still many people who have a vague concept of air conditioning gas charging, as well as still do not know how to properly charge air conditioner gas. Understanding this, the following article would like to guide you on how to properly refill air conditioner gas, hopefully it will help everyone.

Klima gazını uygun şekilde doldurmak için herkes aşağıdaki adımlara başvurabilir ve bunları uygulayabilir:

– Step 1: Connect the gas meter to the gas tank and the air conditioner heater

The first is to wire the gas meter removed from the vacuum pump to the gas tank.

After that, use the scale and reverse the gas bottle to proceed to fill the system with liquid gas.

The process of filling gas for the air conditioner

Proceed by slowly opening the gas cylinder valve. Then gently press the air outlet of the meter. Care should be taken with liquid gas to avoid causing unintended problems.

– Step 2: Open the green valve and start filling the system with gas

If you do not know how to charge the air conditioner once a certain time, you can proceed to charge it many times. Each charge is about 150g when the air conditioner is in cooling mode. However, this way of air-conditioner gas charging is often ineffective and time-consuming.

It is recommended to use a scale to charge liquid gas for the air conditioner. If the scale is not used, the gas should be filled slowly. When the correct pressure is reached for each type of gas, it is recommended to switch to gas filling to conveniently adjust the amount of gas to be charged.

The suction pressure of each gas is different. The pressure of gas R22 is about 65–80 PSI, gas R410A is from 130–150 PSI, gas R32 is from 150–200 PSI.

However, the suction pressure value depends on the air temperature as well as the cleanliness of the array and filter. And to know the suction pressure, it is necessary to check the temperature of the suction pipe. When the machine has enough gas, the suction pipe will be cold about 20 minutes after the compressor starts running.

At the end of the gas charging process for the air conditioner, remove the meter and reinstall the parts of the air conditioner tightly.

*** Things to Note When Recharging Gas for Air Conditioners

You need to know the exact time to change gas.

Cách nạp gas máy lạnh cho từng loại khí gas là không giống nhau. Vì thế, các bạn cần lưu ý một số điều sau:

– For gas R22

The way to charge air conditioner gas for R22 gas is very simple. Since this gas has a low pressure of 65–80 PSI, you can pump gas comfortably.

– For gas R410A

Things to keep in mind when refilling air conditioner gas

Gas R410A consists of 50% gas R32 and 50% gas R125, has a large cooling capacity, ranging from 130–150 PSI. Therefore, this gas cannot be refilled.

When you want to pump gas R410A, you need to suck all the vacuum in the outlet pipe, then pump gas in.

– For gas R32

This gas has very good cooling performance, so the pressure is very high. So when filling gas, it is necessary to withdraw all the vacuum out, to avoid problems when filling gas.

With all types of gas, it is recommended to charge the gas in the correct quantity, not to overcharge or lack the required amount of gas. If the gas is insufficiently charged, the cooling efficiency of the air conditioner is very poor. If too much gas is charged, it is very dangerous, it can cause an explosion in the pipeline if the wiring is not good or damage the air conditioner block.

Above is a guide on how to properly charge air conditioner gas, everyone can refer to it to better understand this issue. From there, it helps to protect the life of the air conditioner and prevent problems that may occur during the refrigerant gas charging process.
