Manufacturing Difficulties Encountered in Generation of New Profile for Rotary Compressor

The market statistics indicate that, the refrigerating compressor market is dominated by the rotary machines. It needs to modify and improve the design and performance of rotary compressors. The effect of the change in any design parameter on performance is to predict accurately for successful design of all types of compressors. The efficient operation of rotary compressors is mainly dependent on proper rotor design and improves the rotor profile so that the flow area through the compressor is maximized while the internal leakage areas are minimized. Also, the internal friction due to the motion between the contacting rotor surfaces should be made as small as possible.
