Reducing Pump Power Consumption by 40 (1000 KW) Through Improved Pump Management in a Central Plant

摘要

Chilled water system data collection and fieldmeasurements performed at the Central Utility Plantof Texas A&M University revealed that 30 - 50 % ofthe primary pump head is consumed by manual andautomatic valves being operated in a partially-openedcondition.A comprehensive analysis was performed todevelop an improved pump management schedule.The results show potential savings of up to 40% ofthe pump power consumption without any capitalinvestment. The optimized schedule is beingimplemented. This paper describes the method andpresents results of the analysis and implementation.
