Variable frequency drives (VFDs) are being used on all chilled-water plant 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 plant design and control. Discussion will include individual component and system performance as well as system design options and control.
