Engineering Study: The Future of Chilled Water Plants and Waterside Economizers

An engineering study was completed to compare a water-cooled centrifugal chiller with a waterside economizer, to a single water-cooled magnetic bearing centrifugal chiller operating in inverted duty - the YORK YMC2 chiller. In this webinar the results of the study will be presented, summarizing the differences between the two options in terms of chiller plant design, first costs, operating costs, and ownership (maintenance, footprint, and controls). Attendees of this webinar will learn:...More
