Water-Cooled Electric Chillers
March 26, 2009 | Updated: May 29, 2012
Although a chiller’s annual energy costs can amount to one-third of its purchase price, choosing one that is most efficient at full or part load might be counterproductive because the ratings don’t measure the efficiency of the overall cooling system.

Air-Cooled Electric Chillers
December 28, 2011
Air-cooled electric chillers can be more attractive in hot, humid climates and certain applications in other climates compared to water-cooled chillers and rooftop units. However, in most of North America, water-cooled chillers are more efficient and have a lower life-cycle cost.
