Reducing Pump Power Consumption by 40% (1000 KW) Through Improved Pump Management in a Central Plant
MetadataShow full item record
Chilled water system data collection and field measurements performed at the Central Utility Plant of Texas A&M University revealed that 30 - 50 % of the primary pump head is consumed by manual and automatic valves being operated in a partially-opened condition. A comprehensive analysis was performed to develop an improved pump management schedule. The results show potential savings of up to 40% of the pump power consumption without any capital investment. The optimized schedule is being implemented. This paper describes the method and presents results of the analysis and implementation.
