The main purpose  

It is a colorless gas at room temperature, a colorless and transparent liquid under its own pressure, non-toxic and non-flammable, has good thermal and chemical stability, and does not corrode metals. It is a low temperature refrigerant and can get a refrigerant temperature of -80°C. 

 

Application

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 refrigeration 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 and an intermediate for fire extinguishing agent 1121, and as a physical foaming agent for polymers (plastics). 

 

Storage and transportation

The R-22 refrigerant cylinder is a pressurized container. It should be stored away from fire, heat sources and direct sunlight. It is usually stored in a cool, dry and ventilated warehouse; it should be lightly loaded and unloaded during handling to prevent cylinders and valves, etc. Accessories are broken. 


 
Refrigeration oil

Refrigerator oils usually used with R-22 refrigerant include: alkylbenzene synthetic oil AB (Alkybenzene), polyol ester synthetic oil POE (Polyol Ester), naphthenic mineral oil MO (Mineral oil), etc.; , What kind of refrigeration oil is finally used in different application places, should follow the recommendations of refrigeration compressor and refrigeration (air-conditioning) equipment manufacturers, or determine the use of refrigerators with the same design and technician requirements according to the specific conditions of the refrigeration compressor and refrigeration equipment. Lubricating oil, that is, choose the equivalent refrigeration oil.

Elimination schedule

R-22 belongs to the HCFC class of substances (the second batch of restricted ODS substances Class II Ozone-depleting Substances) - it is harmful to the ozone layer and has a greenhouse effect, so in developed countries (EU, Japan, the United States), it has been stopped. Initial installation on new air-conditioning and refrigeration equipment; Decree of the State Council of the People's Republic of China (No. 573): "Regulations on the Administration of Ozone-Depleting Substances" have been adopted at the 104th executive meeting of the State Council on March 24, 2010, since June 1, 2010 effective from today. According to the latest adjustment proposal of the Protocol, production and use in 2013 will be frozen at the two-year average levels of 2009 and 2010, respectively, reduced by 10% in 2015, 35% in 2020, 67.5% in 2025, and 2030. Complete phase-out except for maintenance and special purposes in 2018.
