Talk about explosion of air conditioner and refrigerant

Talk about explosion of air conditioner and refrigerant As a household appliance, air conditioners are gradually going to thousands of households. Air conditioners have a history of hundreds of years, so we not only have to ask whether the early production of air conditioners has not exploded? Why the explosion of air conditioners happened in recent years has a close relationship with the refrigerants used in air conditioner production. Freon r22 refrigerant was used in early air conditioners. Freon r22 refrigerant is the most widely used medium and low temperature refrigerant. It is mainly used in household air conditioning, commercial air conditioning, central air conditioning, cold storage and other refrigeration equipment. However, Freon r22 refrigerant has a destructive ability to the atmospheric ozone layer and is gradually phased out. At present, most air-conditioning refrigerants use r410a, r32, etc. Let us look at their characteristics. r22 is colorless, has a weak smell, and is not flammable. r410a is a new type of environmentally friendly refrigerant that does not damage the ozone layer of the atmosphere and is non-flammable. r32 is also an environmentally friendly refrigerant, but it has a huge flaw, which is flammable. Whether it is in a physical store or online shopping, it is very convenient to buy air conditioners. Whether netizens buy air conditioners also depends on the refrigerant used.
