What Are The Common Air Conditioner Refrigerants?

During the working process of the air conditioner, the compressor of the air conditioner will inhale the gaseous refrigerant in the evaporator, compress it to make it a high temperature and high-pressure gas, and then send the high temperature and high-pressure refrigerants gas into the condenser through the expansion valve. Freon will become a low-temperature and high-pressure liquid, and the air blown by the air conditioner is hot air.

Afterward, the low-temperature and high-pressure refrigerant passes through the capillaries and enters the evaporator through the throttling of the capillaries. After the refrigerant enters the evaporator, the space suddenly increases, the pressure decreases, and the refrigerant changes from liquid to gas. During this process, Freon will absorb a lot of heat and the evaporator will become cold. When the indoor unit fan blows over the evaporator, the air blown by the air conditioner will become cold air to achieve cooling.

Therefore, whether the air conditioner is heating or cooling, it is inseparable from the use of refrigerant. The following are some common types of air conditioner refrigerants for your reference.

1. R-22

As the most widely used medium and low-temperature refrigerant today, R-22 is mainly used in household air conditioners, commercial air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, refrigerated dryers, cold storage, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration condensing units, supermarket display cabinets, and other refrigeration equipment. R-22 is an HCFC refrigerant, which will be completely phased out by 2030 according to the Montreal Protocol. Main environmentally friendly alternatives: R410A, R290, R32, etc.

2. R410A

R410A is a new type of environmentally friendly refrigerant that does not destroy the ozone layer. Its working pressure is about 1.6 times that of ordinary R22 air conditioners, and its cooling (warming) efficiency is higher. In recent years, mainstream air conditioner companies have used R410A refrigerant instead of R-22 in the promotion of inverter air conditioners.

Although R410A has zero damage to the ozone layer, its greenhouse gas effect even partially exceeds that of R22. Therefore, R410A is not the ultimate environmentally friendly refrigerant solution for China’s air-conditioning industry. At present, the industry has unanimously recognized that the R290-refrigerant replacement solution is the best and has been recognized by the government.

3. R290

R290, also known as propane, is a natural hydrocarbon refrigerant that can be directly obtained from petroleum cracking. It is a new type of environmentally friendly refrigerant, mainly used in central air conditioning, heat pump air conditioning, household air conditioning, and other small refrigeration equipment.

Compared with the synthetic refrigerant Freon, the molecule of the natural working medium R290 does not contain chlorine atoms, so the ODP value (Ozone Depletion Potential Value) is zero, and it does not have a damaging effect on the ozone layer.

In addition, R290 has a GWP value (Global Warming Potential) close to 0 compared with HFC substances that also have no destructive effect on the ozone layer and have no effect on the greenhouse effect. The carbon dioxide emission reduction obtained by using an air conditioner with R290 as the refrigerant is equivalent to the carbon dioxide emitted by a car with fuel consumption of 10 liters per 100 kilometers running 6,000 kilometers.

4. R32

R32, also known as difluoromethane, is colorless, odorless, non-toxic, low inflammability, has an ozone destruction potential (ODP) of 0, and a global warming coefficient (GWP) of 0.11. These advantages make it one of the alternatives to R22.
