空调水系统阻力计算及水泵选型若干问题
Some problems about resistance calculation and circulating pump selection in air conditioning water systems
摘要：
指出目前一些设计人员在设计空调水系统时 , 仅根据经验值估算管道内径 、 计算管路阻力和选配系统循环水泵的流量和扬程 。 建议应认真进行水力计算 , 合理选择水泵扬程和流量 。

Abstract：
Points out that some designers only use empirical methods in determining the inner diameter of pipeline, calculating system resistance and selecting the rated flow and rated head of circulating pumps in water systems. Recommends that these should be done by careful hydraulic calculation and rational selection of head and water flow of pumps.
