Title: Selection of Screw Compressors for Energy Efficient Operation
Author(s): Reindl and Jekel
This paper discusses the unique characteristics of screw compressors and criteria for selection to yield energy efficient operation when integrated into a built-up industrial refrigeration system. The paper begins with a brief overview of screw compressor technologies, methods of capacity control, and volume ratio concepts. Then, energy efficiency aspects of screw compressor technologies are discussed for both fixed and variable volume ratio configurations. Finally, guidelines for screw compressor selection are outlined.
