Optimization of Chilled Water Systems
MetadataShow full item record
Chilled water systems are one of the major energy consumers in industrial, commercial, and institutional complexes. The centralization of chilled water systems presents numerous advantages, including simplified controls, reduced installation capacity due to diversity, and consolidated maintenance and operation. Centrally chilled water systems present potential energy and cost savings in the following areas: • Chilled water reset. • Condenser water reset. • Chiller sequencing. • Chilled water storage. • Variable chilled water pumping. The feasibility aspect of the above items will be discussed in this paper.
