冷冻站中采用蒸发器侧冷冻水系统变流量或常规的定流量系统的设计配置,对系统的运行能耗有着比较重要的影响.对于蒸发器侧冷冻水系统定流量和变流量的分析表明:一次泵变流量系统不仅可以节省系统的初投资和机房面积,做到冷冻水泵的节能运行,还可以减少冷水机组的全年运行时数,节省冷却水泵的运行时数和能耗.%In the refrigeration plant, design configuration of evaporator side's chilled water variable flow system or conventional constant flow system has important influence on energy consumption of system. The article analyzes evaporator side chilled water system's constant flow and variable flow . The result shows that the primary variable pump flow system can be used not only to save system's initial investment and engine room area, but also reduce one year running hours of chillers and energy consumption of cooling water pump.
