What is the Difference Between Refrigerants R22 and R32?


Which is better, R32 refrigerant or R22? To answer these two questions, we must first understand the nature and purpose of R32 and R22.

R22 Refrigerant

As the most widely used medium and low-temperature refrigerant today, R22 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, and industrial refrigeration. , commercial refrigeration, refrigeration condensing units, supermarket display cabinets, and other refrigeration equipment.

However, due to its strong damaging effect on the atmospheric ozone layer, R22 has been gradually restricted from use, and there will be fewer and fewer air conditioners using this refrigerant in the future.

R32 Refrigerant

The chemical name of R32 is difluoromethane, and the molecular formula is CH2F2. Difluoromethane is a coolant with zero ozone depletion potential. It is a gas at room temperature and is a colorless and transparent liquid under its own pressure. It is easily soluble in oil and insoluble in water.

R32 is a new type of refrigerant. In comparison, the cooling performance is not as good as R22. Moreover, R32 is a flammable and explosive refrigerant with unstable chemical properties, but the harm to the environment is still very small. Gree has now begun to promote R32 air conditioners in the market.

Because R22 refrigerant and R32 refrigerants are not universal refrigerants, the two models cannot be compared. Choosing the right one is the most important. If you have more questions about R22 or R32, welcome to inquire, our professional customer service will be happy to answer you.
