What are the types of household air-conditioning refrigerants, and what are the models of air-conditioning refrigerants?

Now basically every household is equipped with air conditioners, so the question is, what are the commonly used household air conditioner refrigerants? Let me give you a brief introduction, I hope it will be helpful to you.

*R22 refrigerant

R22 is one of the most widely used Freon refrigerants, mainly used in household air conditioners and low-temperature refrigerators. The thermodynamic properties of R22 are similar to ammonia. The standard vaporization temperature is -40.8°C, and the condensing pressure usually does not exceed 1.6MPa. R22 is non-flammable and non-explosive, and it is safer and more reliable than ammonia in use. The unit volume of R22 is about 60% higher than that of R12, and its cooling capacity and saturation pressure per unit volume at low temperatures are higher than those of R12 and ammonia. In recent years, most of the refrigerants of large air-conditioning chillers have been replaced by R134a. Main application: R22 is the most widely used medium and low temperature refrigerant, 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 freezing equipment, marine refrigeration equipment , Industrial refrigeration, commercial refrigeration, refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.

*R-407C refrigerant

Physical and chemical properties: under normal temperature and pressure, R407C is a non-azeotropic mixture of fluoroalkane without chlorine Refrigerant, a colorless gas, is a compressed liquefied gas stored in a cylinder. Its ODP is 0, so R407C is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere. Main application: R407C is mainly used to replace R22, with the characteristics of cleanliness, low toxicity, non-combustibility, and good cooling effect. It is widely used in household air conditioners and small and medium-sized central air conditioners.

*r410a refrigerant

Physical and chemical properties: under normal temperature and pressure, R410A is a non-azeotropic mixture of fluoroalkane without chlorine , A colorless gas, stored in a cylinder is a compressed liquefied gas. Its ODP is 0, so R410A is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere. Main application: R410A is mainly used to replace R22 and R502. It has the characteristics of cleanliness, low toxicity, non-combustibility, and good cooling effect. It is widely used in household air conditioners, small commercial air conditioners, household central air conditioners, etc.

*R134a (tetrafluoroethane) refrigerant

R134a is currently one of the internationally recognized main refrigeration fluids to replace R12, and is often used in vehicles. Used in air conditioning, commercial and industrial refrigeration systems, and used as a foaming agent in the production of hard plastic insulation materials, and can also be used to configure other mixed refrigerants, such as r404a and R407C. Main application: It is mainly used as a refrigerant instead of R12, and is widely used in automobile air-conditioning and refrigerator refrigeration.

After reading the above introduction, I believe that everyone has a general understanding of commonly used household air-conditioning refrigerants.
