中央空调系统水泵设计的若干问题

本文对中央空调系统水泵运行工况进行了分析，通过工程实例计算表明，合理选择循环水泵扬程对系统经济运行具有重要意义；提出冬夏季水泵设置方案应通过综合经济比较合理确定；对于并联运行的水泵，应充分考虑工况转换时系统变化对水泵的影响，并在设计中注意选择水泵的特性曲线；认为水泵在系统中的安装位置应根据系统静压来确定，对中央空调系统水泵设计有参考价值。

Some Problems on Pumps Design in Air Conditioning System

The run situation of air conditioning system pumps was analyzed in the paper, it was indicated that proper pump lift choice is very important to the economical running of system through calculating with engineering apply; the scheme of setting pump in summer and winter should be decided by comprehensive economic comparison it was pointed out that; if pumps were installed parallelly, the influence of variety of system to pumps should be considered sufficiently and the performance curve of pumps should be noticed in the design process; the installed position of pump in the system should be determined by system static pressure, the paper has reference value to pumps design in air conditioning system.
