Air-conditioning refrigerants are generally divided into household air-conditioning refrigerants and automobile air-conditioning refrigerants.
Home ac refrigerant
Among household refrigerants, R22 is one of the Freon refrigerants that is widely used. It is mainly used in household air conditioners, commercial air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, cold storage, and other refrigeration equipment.
R407C is mainly used to replace R22. It has the characteristics of cleanliness, low toxicity, non-combustibility, and an excellent cooling effect. It is widely used in household air conditioners and small and medium-sized central air conditioners.
R410A is used primarily to replace R22 and R502. It has the characteristics of cleanliness, low toxicity, non-combustibility, and an excellent cooling effect, which is widely used in household air conditioners, small commercial air conditioners, and residential central air conditioners.
R134a is currently one of the internationally recognized primary refrigeration fluids to replace R12. It is commonly used in automotive air-conditioning, commercial and industrial refrigeration systems, and as a foaming agent to produce complex plastic insulation materials. It can also be used to configure other mixed refrigerations. Agents, such as R404A and R407C. Main application: It is mainly used as a refrigerant instead of R12 and is widely used in the refrigeration of automobile air conditioners and refrigerators.
Car ac refrigerant
At present, the refrigerants used in automobile air conditioners include R-12, R-134A, R-407C, R-404A, R-22, R-410A; R-12 refrigerant has been eliminated and banned; R-134A refrigerant R-404A refrigerant is mainly used in the refrigeration system of refrigerated trucks at present, but if it is a one-to-two unit (freezer plus air conditioning), it needs to use this refrigerant; R-407C refrigerant is currently pure electric heating, and cooling bus Air conditioners are the first choice and have been widely used in recent years; R-22 refrigerant is presently not in the market; R-410A refrigerant is trialed in small batches by some manufacturers for lighter, smaller, and more energy-efficient units.
