Variable-Speed Compressors on Chillers

Trane applications engineers will discuss the operational, performance and application differences for centrifugal (dynamic compression) and helical-rotary (positive displacement) compressors.  Discussion includes an overview of how variable-speed drives affect chilled water system components, physics of centrifugal compressor chillers and screw compressor chillers, applications that benefit from each technology, importance of proper life-cycle analysis, examples  and application considerations.  Attendees will leave with an understanding of which technologies bring real value to different system applications.

Presenters:   Mike Filler, Mick Schwedler, Brian Sullivan and Lee Cline

After attending you will be able to:

  • Summarize the effects of VFDs on centrifugal and screw compressors in terms of physics (load/lift and performance)
  • Identify applications that offer customer benefits for each technology
  • Understand the importance of accurate life-cycle analysis and offer examples
  • Summarize application considerations to avoid making HVAC design mistakes


There is no fee for this session.


Session begins at 12noon; Lunch will be served at 11:30am.
