All-Variable-Speed Chilled-Water Plant

APP-CMC049-EN

Variable frequency drives (VFDs) are being used on all chilled-water system components (fans, pumps,and chillers), and for good reason. When systems are properly designed and controlled, they offer the opportunity for significant energy savings as well as improved operation. With these new opportunities come new complexities. This ENL discusses all variable-speed chilled-water system design and control. Discussion includes individual component and system performance as well as system design options and control.

After viewing you will be able to:

  • Build the case for variable speed to be used in the context of broader chiller plant design objectives – understanding that it’s not a one size fits all.
  • Identify energy saving opportunities in various chilled water plants.
  • Summarize control options and their energy and complexity impact, regardless of the planned chiller plant design.
  • Summarize the impact of operating on the edges of the safe operating envelope.
  • Summarize limit protection mode considerations and the importance of incorporating into the control system.
