Optimization of Chilled Water Flow and Its Distribution in Central Cooling System
MetadataShow full item record
This paper analyzes the impact of chilled water flow and its distribution on energy efficiency and comfort quality, using the results of a field study conducted for a central cooling production system during 2006 in Kuwait. The paper identifies design and operational inefficiencies and measures their impact in deteriorating the energy efficiency and comfort quality through actual implementation. Over sizing of chilled water pumps was identified as the major design inefficiency. The operational inefficiency included improper distribution of chilled water in the main branches, and bypassing return water through non-operation chillers.
