Until we hit the year 2030 that is. This is why, if you haven’t already noticed, the cost of the R22 refrigerant has increased greatly.

The hydrodechlorination of chlorodifluoromethane (HCFC-22) was performed by a catalytic reaction and noncatalytic thermal decomposition at high temperatures of 400-800 °C. After 47 h of time-on-stream on a supported palladium (Pd) catalyst, the gas phase composition of difluoromethane (HFC-32) is 41 … This study presents the quantification of the emissions of the refrigerants CFC-12 (CCl2F2), HCFC-22 (CHClF2), and HFC-134a (CF3CH2F) from road traffic in Switzerland. These gases are used as refrigerants in car air conditioning systems (A/C-systems) and in cool aggregates for refrigeration transport. All three substances act as greenhouse gases, and CFC-12 and HCFC-22 are in addition 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. 2019-12-25 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.

HCFC-22 is a high 6capacity, efficient refrigerant employed in a significa nt number of air conditioning systems. The majority of these systems utilize mineral oil lubricants. Due to the phase-out of HCFCs, facility owners are considering retrofitting their mechanical systems to alternative refrigerant blends. The selection of a retrofit

ACCIDENTAL RELEASE MEASURES Use personal protective equipment. Evacuate personnel to safe areas. R-22 refrigerant, or Freon, was and still is one of the most popular refrigerants used in the world. R-22 is an HCFC refrigerant and can harm the Ozone layer. It was originally invented by a partnership with General Motors and the DuPont company all the way back in the 1930’s.

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

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.
