Calculations for compression efficiency caused by heat transfer in compact rotary compressors.

Author(s) : ISHII N., MORITA N., KURIMOTO M., et al.

Summary

The paper presents calculations for the compression efficiency of the rolling piston type rotary compressors, which is significantly determined by the heat transfer from the high temperature circumstances outside the compression mechanism into the compression chamber, through the thrust plates. The heat transfer was calculated by the forced turbulent convection heat transfer theory, and the compressed gas pressure was calculated to reveal the compression efficiency. Calculations were made for a representative combination of the major dimensions, such as the cylinder inner radius, the rolling piston radius and the cylinder depth.
