( A Member of the DAIKIN Group). Hydrofluorocarbon (HFC) refrigerants are HCFC-22 and HCFC-141b are the primary HCFCs used in the refrigeration/AC and foams sectors, and as such, represent the majority (97 percent) of HCFCs 28 Jun 2019 One hydrochlorofluorocarbon and two hydrofluorocarbons (HCFC-22, HFC-125, and HFC-152a) were measured in air samples at the Cape Abstract: HCFC-22 (CHClF2, chlorodifluoromethane) is an ozone-depleting substance (ODS) as well as a significant greenhouse gas (GHG). This research investigated the potential for methanotrophic biotransformation of three HCFCs — chlorodifluoromethane (HCFC-22); 1-chloro-1,1-difluoro. Soğutucu akışkanların (CFC ve HCFC) Montreal 1987 Protokolü ile başlayan kısıtlama sürecinde terk çok kullanılan HCFC'ler şunlardır: R-22, R-124, R-123.

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. Replacement of the conventional refrigerant HCFC-22 (R22) is one of the urgent issues to be solved within the scheduled time-frame of the international regulation of the HCFCs. Since there exists no pure fluid that can replace R22 in the same general way as HFC-134a (R134a) is a replacement for CFC-12, HFC mixtures are suggested as possible substitutes. The main aim of this work has been to HCFC-22, an ozone depleting substance (ODS), is used extensively in commercial refrigeration and air conditioning, in the extruded polystyrene (XPS) foam industries (dispersive applications) and also as a feedstock in fluoropolymer manufacture (a non-dispersive use).

Top HCFC-22 abbreviation meanings updated February 2021 The GC-MS-Medusa measurement precisions for HFC-23 and HCFC-22 are determined as the precisions of replicate measurements of the quaternary standards over twice the time interval as for sample-standard comparisons (Miller et al., 2008). Accordingly, they are upper-limit estimates of the precisions of the sample-standard comparisons. 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.

We find pronounced seasonal variations of global emis- In 1993, the EPA established the phaseout framework and the "worst-first" approach that focused first on HCFC-22, HCFC-141b, and HCFC-142b because these three HCFCs have the highest ODPs of all HCFCs. To meet the required 2004 reduction, the EPA phased out HCFC-141b in 2003 and froze the production and consumption of HCFC-22 and HCFC-142b.

R22 (or HCFC-22) is the slightly shorter name for chlorodifluoromethane, a colourless gas most commonly used as a refrigerant or propellant.

These changes make the chemical quick to absorb or radiate heat from the passing air. Many diverse industries have depended on Freon™ 22 (R-22) refrigerant as their go-to hydrochlorofluorocarbon (HCFC) cooling product for decades. 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.
