Refrigerants, also known as refrigerants and refrigerants, are medium substances used to complete energy conversion in various heat engines. These substances typically increase power with a reversible phase change, such as a gas-liquid phase change. Such as steam in a steam engine, the refrigerant in a refrigerator, etc.

　　When a general steam engine is working, it releases the heat energy of the steam and converts it into mechanical energy to generate the motive force; while the refrigerant of the refrigerator is used to transfer the heat from the low temperature to the high temperature. the

　　What happens if the air conditioner does not cool after adding refrigerant?

　　Reason 1: At present, most of the refrigerants used in air conditioners are R134a refrigerants and Chlorodifluoromethane R-22 refrigerants. Air conditioners have a standard range for refrigerant requirements, neither too much nor too little, if the refrigerant ratio is unbalanced If it is not, it will affect the heat dissipation of the air conditioner, and the phenomenon that the refrigerant is not cooled will appear. the

　　Solution: Ask a professional air-conditioning repairman to check it, and the problem can be detected by the air-conditioning pressure gauge. the

　　Reason 2: The service life of the air conditioner is too long, which causes the air conditioner to age. The service life of large household appliances is generally about 15 years. If this period is exceeded, the cooling effect of the air conditioner may decline. the

　　Solution: If the air conditioner has been used for a long time, it is recommended to replace it with a new one. It is not recommended to repair the air conditioner with long service life and aging, because even if the temporary problem is solved, new problems will still appear. the

　　The above is the reason why the air conditioner does not cool after adding refrigerant. If this happens, you still need to ask professional personnel to check it.
