Theoretical study on frictional losses of a novel automotive swing vane compressor

This paper introduces a novel rotary compressor named ‘Swing vane compressor’ (SVC) used for automotive air conditioning systems. By the vane structure which is similar to simple supported beam, SVC can bear higher gas working pressure and rotation speed compared to the sliding vane compressor. The paper introduces the working principle and analyzes frictional model at various contact regions. End-faces frictional losses and vane side frictional loss are the main part frictional losses in SVC. Compared to sliding vane compressor, SVC shows less frictional loss when rotation speed is less than 4000 rpm. Each frictional loss changing with rotation speed also is discussed. SVC provides a selection for automotive air conditioning systems.
