摘要
给出了6种主要混水连接形式的适用压力工况和水泵有效功率计算公式,比较了不同压力工况下各混水连接形式的水泵功率,讨论了不同压力工况下混水连接形式的选择,分析了优选混水连接形式的节能率及混水比对节能率的影响。通过实例说明定流量供热系统中混水连接形式的选择及其节能率。
Presents the suitable pressure conditions of six popular structures of water-mixing connection and the calculating methods for effective power of pumps.Compares the powers of pumps of available water-mixing connection structures in different pressure conditions,and discusses the selection of water-mixing connection structures.Analyses the energy-saving ratios of the optimal structures and the influence of water-mixing ratio on the energy-saving ratio.With a case,illustrates the selection of suitable water-mixing connection structure and its energy-saving ratio in heating system with constant flow.
