TOPIC: Variable Speed Drives for HVAC Applications

 

   


By: Patrick Leake


Presentation Summary:    

Variable speed drives are used throughout HVAC systems to save energy and optimize control.  In this presentation we will review the basics of how a drive works and how to apply them in HVAC applications.  We will examine motor types for drive applications along with common shaft grounding techniques to prevent motor bearing fluting.  We will also review how to properly select a drive based on the location and application and discuss what causes electrical harmonics and their impact on the system.
