Decade Developments of Rotary Compressor

Compressor is the single largest consumer of primary energy (usually electricity) in an industrial refrigeration system and often become a focal point for energy efficiency improvement strategies. This is achieved either through the improvement of existing compressor designs, or by the introduction of new designs that is expected to overcome the drawbacks of existing compressors. This paper presents the summery of development and innovations made in rotary compressors used in refrigeration industry by the researchers in respect to performance, compactness, vibration, method of injection and losses.
