Abstract:建立了供热空调系统中变频水泵扬程、效率和功率与流量和转速间的关联模型．结合并联水泵的运行特性，以最佳点工作流量与水泵转速比范围为参考，理论分析了
对应并联变频水泵电耗极小值运行工况下各水泵转速比配置情况，以采取变压差设定值控制的某变流量空调水系统并联水泵运行工况为算例，仿真研究了一台水泵全
速运行、一台水泵变频运行，两台水泵同步变频运行且转速比相差0.05，两台水泵同步变频运行且转速比相差0.1与两台水泵同步变频运行且转速比相同4种
控制方案的水泵节能效果，理论分析与仿真结果表明，并联水泵转速比的差异将导致一台水泵或多台水泵效率低下，当各水泵转速比相同时，并联水泵的总电耗最小
