R22 Refrigerant Gas in China by Hangzhou Leadhua Refrigeration

refrigerant R22

The R22 refrigerant gas is a chemical that prevents air from coming from your air conditioning system cool, so it’s the very important part. Many AC units which were manufactured a decade ago used to utilize AC refrigerant called R134a that’s also known as Freon* and is noted by the EPA as HCFC-22

One of the mixtures delivered from this essential collusion was R22, which is a hydro chlorofluorocarbon (HCFC). Likewise alluded to as R-22 freon or HCFC-22 freon, the R22 turned into the standard China refrigerant gas utilized in cooling frameworks from that point onward.


R22 refrigerant R22 is an HCFC refrigerant used for residential and commercial air conditioning and for medium- and low-temperature commercial refrigeration applications, including: food service, supermarket display cases, food storage and processing, and transport refrigeration systems. It is also used as foam blowing agents and intermediate to produce fluorine polymer.

How to use R22 Refrigerant gas?

For refilling R22 gas, you’ll need; AC manifold gauge set, Vacuum Pump with 1-4 horsepower, and Refrigerant.

First, locate the suction line(low side) on the air conditioner, and discharge line – high side. These lines are usually located behind a window AC, or in split AC in the outdoor unit. You can find it above the discharge line. Since discharge line is warm to touch, it is normally used for recharging gas into AC.

Unscrew the bolt of the suction line, loosen the screw inside with a Torx hex key. This screw act more like a valve, which doesn’t allow refrigerant flow in, or out until it gets closed. For this reason, loosening screw is must for filling AC gas.

Remove the bolt on left, and connect with blue hose of AC diverse gauge to this port. Connect the yellow hose with a vacuum pump. Remove all the air from the system. This step is important as any moisture left inside the compressor might damage it.

Once you close all valves of the AC manifold gauge, connect the yellow hose with a refrigerant tank. Before opening the tank knob, slightly loosen the yellow hose towards the manifold end,an open knob of a cylinder for a second and close it. This will remove all air inside the pipes. Tighten yellow hose again

Next, open the low knob side of the manifold for 3-4 seconds and close it. Turn ON the AC, and let the compressor kicks in with time. Once the compressor starts, open the low side of the valve again of the manifold, and keep it open for 4 seconds, then close it for 2 seconds.

By doing this, you can note the exact spot where pressure settles in the gauge when you close the valve. Thus, keep opening and closing the valve until the pressure finally settles between 60-70 PSI. Once it reaches the desired range, close the manifold valve, close the refrigerant tank knob, unscrew the blue hose from the suction line, and unscrew the yellow hose from the refrigerant tank.

What is the function of R22 Refrigerant gas?

R22 refrigerant called by its chemical name, hydro chlorofluorocarbon 22 (HCFC-22), it’s the main key to absorb and remove heat from a space. For this critical function, R22 refrigerant has been in use for years in mini-splits, heat pumps, central air conditioners, car AC systems, and other refrigeration products. However, the main uses of R22 come in domestic air conditioners including; split AC, window AC, packaged AC, and also in other central air conditioning systems. This refrigerant gas is non-toxic and non-flammable which makes it secure for industrial and domestic purposes.
