Hydrocarbon refrigerants


Why R-32 May Be the Refrigerant of the Future

In the late 1980s, those of us of a certain age became familiar with an international agreement called the Montreal Protocol. The goal of this agreement was the phaseout of ozone-depleting chlorofluorocarbon (CFC) refrigerants. Then, in 1999, Title VI of the U.S. Clean Air Act was modified to phase out high global-warming hydrofluorocarbon (HFC) refrigerants. Now, once again, the fix has been deemed inadequate, and we are being asked to jump into a new generation of refrigerants.
