| 摘 要： | 以实际工程为例，利用简化模型从理论上推导出中央空调冷冻水循环水泵多台并联运行时，水泵参数的选样原则。阐述了水泵扬程选取过高，是系统低负荷、水泵单台运行不稳定、效率低、甚至烧毁电机的主要原因。

| Abstract: | to take actual engineering as an example, make use of to simplify the pattern to deduce a central air condition refrigeration water cycle water pump to have another the stand parallel running from the theory, the water pump parameter chose the kind priniple to elaborate the water pump lists selects by examinations high, is main reason to system low burden, the water pumps the single stand running unsteady, the effciency is low and even destroys by fire to lay foundation stone. |
