The refrigerator system is leaking. Can the refrigerant R600a be replaced by R22 after repair welding?

The refrigerator system is leaking, and the refrigerant R600a cannot be replaced by R22 after repair welding.

R600a refrigerant is mainly used in refrigeration equipment such as refrigerators, freezers, water dispensers, automobile air conditioners, central air conditioners, dehumidifiers, cold storages, commercial refrigeration, ice water machines, ice cream machines, refrigeration and condensing units, etc., at the same time It can also be used in aerosol propellants, medical aerosols, insecticide propellants, polymer (plastic) physical foaming agents, and magnesium alloy protective gases.

As the most widely used medium and low-temperature refrigerant today, refrigerant R-22 is widely used in household air conditioners, commercial air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, refrigerated dryers, marine Refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.

Extended information:

Refrigerant R-22 is generally used in air conditioners or in the first stage of a double-unit cascade. As a high-temperature end refrigerant, it has greater refrigeration intensity than ordinary refrigerants. It can also be used as an aerosol spray for pesticides and spray paints, and can also be used to produce fire extinguishing agent 1211; it is the basic raw material for the production of various fluorine-containing polymer compounds. It is an HCFC refrigerant and will be completely phased out by 2030 according to the Montreal Protocol.

The main domestic manufacturers include Quzhou Juhua Group, Shandong Dongyue Group, Jiangsu Meilan Chemical, Sanaifu, etc. Major international brands include DuPont, Honeywell, Arkema, etc. However, since developed countries have phased out R22 in advance and are no longer allowed to produce this product in their own countries, all R22 sold on the market is produced by domestic OEMs.
