In this article originally published in Mission Critical magazine, the experts at Johnson Controls explore the benefits and drawbacks of air- and water-cooled chiller systems. Exploring important metrics for measurement, CAPEX costs and other important considerations, the case is made for both systems, including some considerations that are often overlooked:
“Visually, the plume produced by water towers may be objectionable. This may swing the decision toward an air-cooled chiller selection, but there is another option. In some situations, a geothermal subterranean loop can be dug to use the ground for condenser-water heat rejection.”
The article also shares considerations around maintenance costs and water costs – all of which may help guide you to one solution over the other.
