Introduction of R22 gas
R22 is a member of the Freon family and belongs to the category of hydrochlorofluorocarbons. As the most widely used medium and low temperature refrigerant today, refrigerant R-22 is widely used in reciprocating compressors as a refrigerant in industrial, commercial, and household air conditioning systems.
It can also be used as aerosol spray for pesticides and spray paint, and it 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.

The main purpose
As the most widely used medium and low temperature refrigerant today, R-22 is 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.
Difluoromonochloromethane can also be used as a raw material for the production of polytetrafluoroethylene resin, an intermediate for fire extinguishing agent 1121, and as a physical foaming agent for polymers (plastics).
Used in reciprocating compressors, as refrigerants in industrial, commercial, and domestic air-conditioning systems; it can also be used as aerosol propellant for pesticides and spray paint, and it can also be used to produce fire extinguishing agent 1211; it is the production of various fluorine-containing polymers The basic raw material of the compound.
R22 belongs to the HCFC refrigerant. According to the Montreal Protocol, it will be completely phased out before 2030.
The main environmentally friendly alternatives: R404A, R410A, R290, R23, R407C, R411A, R417A, R1270.
Major international brands: DuPont, Honeywell, Arkema, Frioflor etc. However, because developed countries have already phased out R22 ahead of schedule, the production of this product is no longer allowed in their own countries, so the so-called imported R22 sold on the market is actually domestic OEM production.
It is generally used in air conditioners or a two-machine cascaded first stage, as the high-temperature end refrigerant, which has greater refrigeration strength than general refrigerants.

Refrigerant R22 packaging
Disposable steel bottle packaging:
1. 13.6kg/bottle, 22.7kg/bottle;
2. reusable steel bottle packaging (recycling and packaging steel bottles): 400kg/bottle, 800kg/bottle.
Refrigerant R22 storage and transportation
Refrigerant R22 cylinders are pressurized containers. They should be stored away from fire, heat, and direct sunlight. They are usually stored in a cool, dry and ventilated warehouse; they should be loaded and unloaded with care to prevent damage to the cylinders, valves and other accessories.
What refrigeration oil matches refrigerant R22?
The refrigerating oils usually used with refrigerant R22 are: Suniso 3GS, 4GS, 5GS, KunLun 3GS, 4GS, 5GS, ICEMATIC SW220, CP-4214-320, LUNARIA KT15, 22, 32, 46, 56, Capella WF68, etc.; What kind of refrigerating oil is finally used in different equipment and different application places should follow the recommendations of the refrigeration compressor and refrigeration (air-conditioning) equipment manufacturers, or determine the use of the same design and technical requirements according to the specific conditions of the refrigeration compressor and refrigeration equipment.
