北京某数据中心空调系统能耗分析与启示

Analysis and Enlightenment of Annual Energy Consumptionof AirConditioning System in a Data Centerin Beijing

以北京某数据中心全年运行能耗数据为基础,分析基于典型水冷架构数据中心全年度PUE变化趋势。通过解构PUE中制冷因子组成与占比,分析制冷系统各组件与IT负载率、湿球温度的关联度。对于第三方数据中心常规水冷制冷系统能效治理,应偏重冷源部分冷水机组、冷却水泵、冷却塔的调忧。

Based on the annual operation energy consumption data of a data center in Beijing,this paper analyzed the PUE change trend of the data center based on typical watcr-coolingarchitecture.By decomposing the composition and proportion of refrigeration factors in PUE,the correlation between each component of therefrigeration system and IT load rate,wet bulbtemperature was analyzed.For the energy efficiency management of conventional water-cooled refrigeration systems in the third-party data center,the optimization of chiller,coolingwater pump and cooling tower should be emphasized.
