Optimize Cooling Water Supply To Reduce Distribution Costs

摘要

and September 2012 and January 2013.) The last article examined what can be done on the supply side—cooling towers, chillers, and air coolers. Now we'll look at minimizing expenses in distributing cooled or chilled water. Reducing distribution costs for cooling and chilled water is often one of the easiest and quickest methods of reducing energy use in water cooling, yet most plants have never investigated this area. The water circulation pumps for cooling and chilling systems are generally centrifugal pumps and these are often incorrectly sized for the demand. This is either due to expansion/ contraction of the system, poor initial specification, or changes to the system that have not been logged correctly. The cooling-water map (see March 2012) is an invaluable tool in locating these changes to the system and can act as a road map to saving energy.
