浅谈数据中心冷源群控系统采用的节能措施

Discussion on chiller group control system of data center Energy saving measures

机房PUE(Power Usage Effectiveness能源使用效率)是衡量数据中心是否节能的重要指标,PUE的计算方式为PUE=总用电量除以IT负载用电量,显而易见在PUE的计算中,增加IT负载耗电量的占比就能提升PUE,其中除去IT负载产生的用电量,当属冷源系统所产生的能耗在总用电量中的占比最大,而IT负载代表的是数据中心的算力体现。因此采用调整冷源群控系统的方式是降低PUE指标的最直接方式。本文介绍了目前主流数据中心所采用的冷源群控节能方式,并对其进行分析,望能提供相应参考方式。

PUE(power usage)of computer room Effectiveness(energy efficiency)is an important indicator to measure whether the data center is energy-saving.PUE is calculated as PUE=total power consumption divided by it load power consumption.It is obvious that in PUE calculation,increasing the proportion of it load power consumption can improve PUE.Excluding the power consumption generated by it load,the energy consumption generated by cold source system accounts for the largest proportion of total power consumption,while it load power consumption accounts for the largest proportion Load represents the computing power of the data center,so adjusting the cold source group control system is the most direct way to reduce the PUE index.This paper introduces the energy saving mode of cold source group control adopted by the current mainstream data center,and analyzes it,hoping to provide the corresponding reference.
