Waterside Economizer at The Energy-Water Nexus

Waterside economizers have gained prominence in recent years because of greater focus on reducing utility costs and increasing efficiency. While data centers are taking most of the limelight in waterside economizer applications due to their ever-increasing loads and new ASHRAE thermal guidelines,(1) the application of these systems in other industries is also showing promise. This article discusses the applicability of waterside economizers at dairies, offers guidance on various design and control considerations for optimal performance, and provides field data from one such installation.
