WebApr 16, 2024 · The most popular hydrofluorocarbon (HFC) refrigerants for new commercial air conditioning systems in the US today include R-410A, R-407C, and R-134a, but there are still plenty of R22 systems out there. The next generation fluids will have lower global warming potentials (GWP) but many are classified as mildly flammable. WebJan 26, 2024 · By the early 1970s, it was discovered that CFC and HCFC refrigerants caused a breakdown of the ozone layer. In particular, while HCFCs are comparatively lower in ozone-depleting potential and CFCs have a particularly high ozone-depleting potential, both still wreak havoc. The low reactivity of CFCs gives them a lifespan that can exceed … WebFundamental properties of HFCS, HFOS & HCFOs, also includes HCFCs used as feedstocks.
