Chilled water systems provide cooling to a building by using chilled water to absorb heat from the building’s spaces. A chiller provides consistent temperature and pressure to your industrial process. %aJ�P��BB�T � The water leaves the chilled water evaporator at 45°F or 7°C. and Owner Sales, Joe Leichner writes, “While the chiller is the heart of a chilled water system, its support system of components and controls are equally critical to attain high efficiency levels.” His article titled, “Evaluating Chilled Water Cooling System Components,” reviews water pumps, cooling The chiller is the section of the system where an exchange of heat occurred between the water that goes to the building and the evaporator. 0000012120 00000 n 747 0 obj <>/Filter/FlateDecode/ID[<39C18E67D96064BE4CC0F956757D3E0F><5EF81B6C03CEB341BF0E499534964ACD>]/Index[675 229]/Info 674 0 R/Length 247/Prev 1316967/Root 676 0 R/Size 904/Type/XRef/W[1 3 1]>>stream An alternative chilled water system is a closed loop system, which means water is used as the cooling media and does not exit or enter the system once it is in operation.
