Review of refrigeration compressors, their applications and recent research activities.

Author(s) : GROLL E. A.

Summary

The paper contains a review, including descriptions, certain design features and characteristics, of the most widely used and commercially available compressors that are commonly used in vapour compression cycles for refrigeration and air-conditioning applications. In addition, the recent research activities with respect to these compressors as observed through the publication at the biannual International Compressor Engineering Conference at Purdue is discussed. There are two basic types of compressors: positive displacement compressors and dynamic compressors. Positive displacement compressors increase the pressure of the refrigerant vapour by reducing the volume of the compression chamber by means of work usually applied to the compressor's shaft mechanism. Dynamic compressors increase the pressure by a continuous transfer of angular momentum from the rotating parts of the compressor to the fluid, followed by the conversion of this momentum into a pressure rise. Both types are described.
