Abstract
The paper gives results of comprehensive calorimeter tests on a semihermetic compressor with chlorofluorocarbon (CFC)-114, hydrofluorocarbon (HFC)-236ea, and HFC-236fa over a wide range of temperature test conditions: evaporating temperatures from 0 to 35 C and condensing temperatures from 40 to 110 C. Parameters assessed as criteria for performance evaluation and for reliable performance include: cooling capacity; electric power input, current, and voltage; coefficients of performance; compressor volumetric and isentropic efficiencies; and discharge and oil temperatures. Polyolester oil was used as lubricant in the compressor.
