摘　　要：定义了单热源枝状热网热媒输送的需用功率,指出这一最小功率可以由零压差点位于热源出口的分布式水泵系统实现。定性分析了影响该分布式水泵系统节能率的各个因素,结论可供实际工程中分布式水泵系统的设计与改造参考。Defines the required power of hot water transporting in tree networks with a single heat source, and points out the minimum power can be realized by distributed water pump systems, of which the zero pressure difference point locates in the exit of heat source. Analyses factors that affect the energy saving ratio of systems, the conclusions can be used as references for designing and reconstructing.
