Chilled Water System For University Campus PDF

Until 2005, each of the 30+ buildings on Missouri State University’s campus in Springfield was air conditioned via individual water chillers or packaged air-conditioning systems. Many of the buildings on this 160 acre (65 ha) campus are heated using steam from a central boiler plant, distributed via a network of subterranean pipe tunnels, but the air-conditioning systems were a building-by-building mix of direct expansion packages, centrifugal chillers, steam-driven absorption chillers, and air-cooled chillers. The university recently opted to construct a campus district chilled water system and connect many (but not all) of its buildings, making use of new and existing equipment.
