闭式蒸发冷却冷水机组在大柳塔电厂内用于湿冷塔内循环水降温时，对其耗水量进行了测试分析.得出在测试条件下，机组运行时耗水量范围为：250~350kg/h；机组最小耗水量257.6kg/h对应的二次/一次空气风量比为0.5；循环水流量与耗水量成线性正比关系，当循环水流量从6m/h增加到15m/h时，耗水量从233kg/h增加到339.2kg/h。机组进风口的干湿球温差，进出水温差的变化趋势都与耗水量的变化趋势基本一致。

An evaporative cooling chiller in Da Liuta electricity plant can reduce the temperature of the circulating water . Its water consumption were tested and analyzed.Under the test condition,its water consumption range during runtime is 260~350kg/h;The minimum water consumption 257.6kg/h corresponding to the winds ratio 0.5;The circulating water flow and water consumption is linearly proportional relationship,when recycled water is from 6m3/h to 15m3/h,water con-sumption from 233kg/h to 339.2kg/h. The difference between air inlet wet and dry bulb temperature,between inlet and outlet water temperature are consistent with the trends of water consumption.
