北京某数据中心全年用水量分析

Analysis of annual water consumption of a data center in Beijing

介绍了北京某数据中心用水量设计及运行的工程实例,以全年用水量的实测数据为基础进行研究,计算数据中心的水资源使用效率实测值,分别探讨了冷却塔补水量对用水量的影响以及蒸发损失、浓缩倍数、冷却水循环水量、制冷系统自然冷却时间对冷却塔补水的影响,最后给出了在数据中心水资源容量规划、冷却循环水补水系数取值及冷却水补水储存容量估算时的具体建议。

This paper introduces an engineering example of water consumption design and operation in a data center in Beijing.Based on the measured data of water consumption in the whole year,calculate the measured water use efficiency of data center,discusses the influence of cooling tower supplement water on water consumption,as well as the influence of evaporation loss,concentration multiple,cooling water cycle water quantity and natural cooling time of cooling system on cooling tower supplement water.Finally,some suggestions are given in the data center water resource capacity planning,cooling water circulating supplement water value and cooling water supplement storage capacity estimation.
