NIST’s study, entitled “Limited options for low-global warming potential [GWP] refrigerants,” focused on residential and small-commercial single-package and split air conditioning systems, but the authors said their conclusions also generally apply to room air conditioning units and other refrigeration and heat-pump systems currently using common, ozone-depleting refrigerants such as R-410A or R-22, which are still used in some developing countries today. “The takeaway is there is no perfect, easy replacement for current refrigerants,” NIST chemical engineer Mark McLinden said.
