The development of a new generation of open-type screw compressor based on mathematical modelling and experimental investigation.

Author(s) : LIU Y., WU H., JIANG S., et al.

Summary

The screw compressor is widely used in air conditioning and industrial refrigeration. The performance of an old series of open-type screw compressor has been required to be improved in recent years. In this paper, the development of a new generation of open-type screw compressor was reported. In order to make the new compressor has good performance, extensive mathematical modeling and experimental investigation were carried out. The working process, pressure pulsation, bearing load and oil distribution of the screw compressor were studied theoretically and experimentally. Based on these studies, the design method of the rotor profile and the guidelines for setting up the clearance between the rotors were proposed. Also, the design of the oil supply system and the mechanism for capacity control were introduced. Moreover, a software package called SCCAD for the design of screw compressor was developed. Finally, a new generation open-type screw compressor with 18 models was developed, and the measured performance data of the compressor was compared with the old generation. The application of the new compressor in air conditioning and industrial refrigeration was also reported in the paper.
