Feb 3, 2020 What Is R-22 Refrigerant? R-22 is the most common form of the HCFC-22 chemical, a type of Class II ozone-depleting substance. You likely know

As a refrigerant, HCFC-22 is the chemical that heats or cools the air that HVAC systems produce. When this fluid passes through the parts of the HVAC unit, it changes into either liquid or gas. These transformations then make the refrigerant hot or cold. These changes make the chemical quick to absorb or radiate heat from the passing air.

Starting on January 1, 2020, U.S. production and import of HCFC-22 will end. The HCFC-22 phase-out is a part of the EPA’s HCFC phase-out schedule, which the United States agreed to in 1987 as part of the Montreal Protocol. HCFC-22 contributes to depletion of the ozone layer, and its production is scheduled to halt by 2020 in the United States.

HCFC-22 costs are a tiny fraction of finished product costs and so do not materially affect the size of those markets. Consequently leakage, in terms of increased use of HCFC-22 due to lower costs, is not significant. Nor would there be any economic incentive for HCFC-22 plants to be constructed speculatively since, even if the product were given

It's been the most widely used choice for air conditioning (AC) and medium- to low-temperature commercial refrigeration because of its dependability—and because it works. R22 (or HCFC-22) is the slightly shorter name for chlorodifluoromethane, a colourless gas most commonly used as a refrigerant or propellant. Unfortunately, many HCFCs, including HCFC-22 (a principal component of the trade name product “ Freon ”) contribute both to global warming and can, to a lesser degree, serve to deplete the ozone HCFC-22 (Chlorodifluoromethane) There are two GML programs that measure HCFC-22.

The photodegradation of chlorodifluoromethane (HCFC-22) was investigated using microwave/UV/TiO 2 photocatalysts hybrid system. The microwave discharge electrodeless mercury lamp (MDEML) used in this study showed mainly atomic Hg emission lines at 253.7 nm. The decomposition efficiency of HCFC-22 increased with decreasing inlet concentration and with increasing reactor residence time. HCFC-22 is used as a refrigerant in several different applications, as a blend component in foam blowing and as a chemical feedstock for manufacturing synthetic polymers. In developed countries, the scheduled phase out of HCFC-22 consumption will occur by … Hcfc-22 cfc-12 | C2HCl3F4 | CID 17911091 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

Developing countries have become the largest producers of HCFC-22 in recent years according to data compiled by the Ozone Secretariat of the World Meteorological Organization. Emissions of all HFCs are included in the UNFCCCs Kyoto Protocol.

HCFC-22 (CHClF 2) and HFC-134a (CH 2FCF 3) are two major gases currently used worldwide in domestic and commercial refri-geration and air conditioning. HCFC-22 contributes to strato-spheric ozone depletion, and both species are potent greenhouse gases. We find pronounced seasonal variations of global emis- 2019-12-25 · Chlorodifluoromethane, or HCFC-22, is a compound used primarily as a refrigerant.It was developed to replace Chlorofluorocarbons (CFCs), when their phaseout began in the late 1970s. HCFC-22 is used as a refrigerant in several different applications, as a blend component in foam blowing and as a chemical feedstock for manufacturing synthetic polymers. In developed countries, the scheduled phase out of HCFC-22 consumption will occur by 2020 due to its stratospheric ozone depleting properties. Normalized by the percentages of vehicles using different refrigerants in their MACs, the emission rates of HFC-134a, HCFC-22, and CFC-12 are 52.2, 329, and 59.5 mg h –1 veh –1, respectively. This emission rate of HFC-134a is approximately 10 times higher than those previously reported in Europe for stationary conditions and a whole-lifetime average of fugitive losses.
