2 MARKET TRENDS

Applied systems comprise a heat- source chiller and air-side equipment such as air-handling units (AHUs) and fan coil units (FCUs), along with pumps used to convey chilled and cooling water, water pipes, cooling towers to dissipate heat outdoors, and other equipment. The total cost of a chiller system varies a great deal and depends on the individual systems and applications. In terms of value, total world demand for air-side AHUs and FCUs combined is roughly the same as demand for chillers.
