The paper gives results of tests of both HFC-236ea and CFC-114 at a range of temperatures covering surface craft and submarine chiller conditions. Evaporating temperatures ranged from 1.7 to 12.8 C, and condensing temperatures from 40.6 to 65.6 C, in order to develop a nine-point test map. Polyol ester oil was used with the refrigerants. The tests evaluated suction and discharge pressures, their difference and ratio, cooling capacity, electric power input, compressor energy efficiency ratio (coefficient of performance), electric current, and compressor volumetric and isentropic energy efficiency. Compressor discharge, motor winding, and oil temperature were also monitored. HFC-236ea is one of the strongest candidates for a CFC-114 alternative in surface craft and submarine chillers. Some material compatibility and oil miscibility work has also been performed in support of HFC-236ea as a refrigerant.
