空调水系统末端“以泵代阀”的节能分析
Energy saving analysis on replacing control valves by frequency controlled pumps in terminal of air conditioning chilled water system
摘要：
以FCU+PAU空调一次泵定流量系统为例，分析“以泵代阀”系统的形式和特点，计算并比较“以泵代阀”系统与传统系统的空调供冷季节水泵能耗。结果表明，“以泵代阀”系统有一定节能效果，但水泵变频时电动机损耗占水泵总功耗的比例较大。

Abstract：
Taking the primary pump constant flow chilled water system of FCU with PAU air conditioning system as an example, analyses the mode and characteristics of the new system using frequency controlled pumps replacing control valves, calculates and compares the energy consumption of the pump between the new system and traditional systems in cooling seasons. The results show that the new system has a certain energy saving potential, but motor loss has a large proportion to total pump power when variable frequency pump is used.
