Abstract The paper discusses a thermodynamic analysis of HFC-236ea and HFC-236fa as ozone-safe CFC-114 alternatives in a vapor-compression cycle at high-temperature heat-pump conditions. The cooling capacities and the coefficients of performance (COPs) are evaluated. Parameters assessed as criteria for performance evaluation and for reliable performance were: cooling capacity; electric power input, current, and voltage; COP; compressor volumetric and isentropic efficiencies; and discharge, winding, and oil temperatures. With all three refrigerants, the compressor ran 1800 hours without failure and without indication of excessive noise or vibration.
