The design of a new generation of twin screw refrigeration compressors.

Author(s) : XING Z., WU H., SHU P.

Summary

The design of two series of twin screw compressors for use in refrigeration applications is reported in the paper. The capacity range for the open-type series is 85 to 4300 m3/h, and for the semi-hermetic series 120 to 2600 m3/h. The rotor profile and other design parameters were optimized with the help of the software package SCCAD. Many new features such as variable built-in volume ratio, anti-friction bearing and automatic capacity control were adopted in the design. The new compressors also proved to be suitable for operating with economizer and liquid refrigerant injection systems.
