对一所72000平方英尺（6700平方米）的学校的闭环地源热泵（GSHP）系统的四种不同泵和管道系统的能耗进行了评估。考虑了一个分散系统，每个区域有单独的回路和循环泵，以及三个中央系统（变速驱动泵、恒速驱动泵和一次-二次泵回路）。分散式系统每年使用13100 kWh，带变速驱动（VSD）的泵消耗18800 kWh，恒速泵需要108600 kWh，一次泵消耗18800 kWh- 二次系统耗电65500千瓦时。介绍了设计细节、建筑荷载、泵控制、运行特性和表格结果。单位:双引用:研讨会论文，佐治亚州亚特兰大，2001年

An evaluation is presented for the energy consumption of four different pump and piping systems for a closed-loop ground-source heat pump (GSHP) system for a 72,000 ft2(6700 m2) school. One decentralized system with individual loops and circulator pumps for each zone and three central systems (variable speed drive pump, constant speed drive pump, and primary-secondary pump loop) were considered. The decentralized system used 13,100 kWh per year, the pump with the variable speed drive (VSD) consumed 18,800 kWh, the constant speed pump required 108,600 kWh, and the primary-secondary system used 65,500 kWh. Design details, building loads, pump control, operating characteristics, and tabular results are presented.Units: Dual
