Résumé

The research was conducted in order to better identify the torque loss of a hermetic rotary compressor for one revolution, and to directly obtain the actual shaft power of the compressor. A testing compressor and a gas cycle type simplified calorimeter were developed for direct measurement of the compressor torque. On the other hand, effective compressive torque for compressing refrigerant gas was predicted theoretically. From both experimental and theoretical results, torque loss of the compressor was determined. A loss of over-compression could be revealed from the torque loss experimentally. Overall adiabatic efficiencies of compressors obtained by the actual shaft power were 1.1 to 3.5% higher than former overall adiabatic efficiencies obtained by the motor output.
