摘要
比较一次泵变流量系统部分流量下不同控制方式的节能效果。指出水泵的综合效率η对其总输入功率的影响不可忽视;给出不同控制方式节能率的估算公式和影响因素;采用定末端压差控制是大型系统的理想选择。
The energy saving effect of several control modes was contrasted in variable primary flow chilled water system under partial flow. The results show that the pump comprehensive efficiency, η, is noticeable to the influence of its total power input. The estimating formula and influencing factor were offered in the differential pressure control modes. Using constant terminal differential pressure control is an ideal choice in large-scale system.
