Summary

The paper presents a fundamental optimum design which yields a high compressor performance in mechanical and volumetric efficiency of a rolling-piston rotary compressor. The frictional power losses at each pair of machine elements were calculated by an analytical method revealing the dynamic behaviour of rolling-piston rotary compressors, and the refrigerant leakage from axial and radial clearances was calculated by the incompressible and viscous theory assuming an entire turbulent leakage flow. Computer calculations were made for a number of combinations of the major dimensions for various suction volumes. Calculations for the mechanical and volumetric efficiency resulted in an optimum combination of major dimensions for various suction volumes of the rotary compressor.
