Description:
The report gives results of a preliminary evaluation of a new hydrofluorocarbon (HFC-236ea or 1, 1, 1, 2, 3, 3-hexafluoropropane) as a possible alternative for chlorofluorocarbon (CFC)-114 (1, 2-dichloro-1, 1, 2, 2-tetrafluoroethane) refrigerant in chillers and high-temperature industrial heat pumps. (NOTE: HFCs form a class of chemicals having the potential to replace stratospheric ozone depleting substances such as CFCs and hydrochlorofluorocarbons (HCFCs).) Evaluation tests included an examination of the flammability, stability, thermophysical properties, lubricant/refrigerant characteristics, materials compatibility, inhalation toxicity, and refrigeration performance HFC-236ea was found to be an excellent alternative for CFC-114 refrigerant.
