Variable Speed Tri - Rotor Screw Compression Technology

摘要

It is the intent of this paper to compare two compression approaches using helical screw technology in large flooded evaporator water cooled chillers. The paper will compare the basic compression losses of a twin screw compressor to that of a tri-rotor helical screw set with equivalent displacement. Losses will be evaluated at both full load and part load operation. It will be shown that for large water cooled chillers the tri rotor concept offers improvement in both full and part load performance.
