摘要
通过分析冷冻水管路特性随空调负荷变化的特点 ,得出了计算空调冷冻水泵变频调速运行总能耗的一般关系式。研究表明 ,在中央空调系统中 ,由于冷冻水管路特性曲线随空调负荷而变化 ,在确定水泵变频调速运行的能耗时已不能直接应用泵的相似定律 ;变频冷冻水泵的能耗并不与转速或流量的三次方成正比 ,而是与空调负荷、空调用户的流量分配及空调用户的位置等有关。
Based on analyzing the characteristics of chilled water loop resistance varying with the air-conditioning loads,a general formula of the energy consumption of variable speed chilled water pumps is obtained.It shows that the pump affinity laws can't be directly used to determine the energy consumed by variable speed chilled water pumps.The consumed energy is not proportional to the cube of speed of the pump,but varies with air conditioning loads,capacity or loads distribution characteristics and the location of loads or AHUs(air-handling units)…
