HCFC-22. Air conditioning equipment generally runs most efficiently on the type of refrigerant it was designed for, but when the time does come to replace or retrofit your system, there are many non-ozone-depleting alternatives available. What Alternatives Can Be Used Instead of HCFC-22? Many non-ozone-depleting alternatives to HCFC-22 are
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.

The retrieval of CFC-11, CFC-12, and HCFC-22 are not standard products for many of these instruments, and as such, a harmonization of retrieval parameters between the sites has been conducted. The retrievals of these species from the FTIR spectra are sensitive from the surface to approximately 20 km, while the ACE-FTS profiles extend from approximately 6 to 30 km.
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. As HCFC-22 production is phased out, chloroform production is expected to decrease significantly.
HCFC-22 (Chlorodifluoromethane) There are two GML programs that measure HCFC-22. The longest and most complete measurement of HCFC-22 is from the HATS flask GC-MSD program (data displayed below). The CATS in situ GCs also measure HCFC-22, however the data are less precise than the flask measurements.
It was originally invented by a partnership with General Motors and the DuPont company all the way back in the 1930’s. production of HCFC-22. This guideline does not cover a) direct emissions from the combustion of fossil fuel occurring during the production of HCFC-22 and b) indirect emissions from the purchase of energy (electricity or steam) used for HCFC-22 production. These GHG emissions are covered by the cross-sectoral guideline on stationary combustion. 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.
