Enhancing Air-Cooled-Chiller Performance With VFDs

Variable-frequency drives help air-cooled systems overcome traditional efficiency drawbacks

Air-cooled chillers long have been the choice for system designers who are focused on simplicity and low cost. A system based on an air-cooled chiller usually is less expensive to install and easier to maintain than other types, such as water-cooled systems. On the other hand, these advantages typically have come at the expense of lower efficiency.

New technology has enabled manufacturers of air-cooled chillers to overcome this efficiency disadvantage by incorporating variable-frequ
