摘　　要：为了研究已经给定的某数据中心可行的节能运行策略,本文基于建筑图纸建立仿真模型,通过改变机房设计温度、冷冻水进出温度及温差、冷水机组性能系数(COP),寻找节能方案,使用电能利用效率(PUE)及数据中心性能系数(COP_(dc))进行方案评价。结果表明,经过节能运行策略改良后,该运行方案下理论上PUE可以达到1.34,而其常规方案运行的PUE为1.48。本文提出的方案可行性高,在允许条件下甚至可以达到更低的PUE。In order to study the feasible energy-saving operation strategy of a certain data center,this paper aims to provide a feasible energy-saving strategy,and verify the performance of existing energy-saving strategies in this model.A simulation model based on architectural drawings has been established in this paper,looks for energy-saving strategy by changing the design temperature of the computer room,the temperature of chilled water,and the coefficient of performance(COP)of the chiller,and then evaluates the solutions through the power usage effectiveness(PUE)and Coefficient of Performance of data center(COP_(dc)).The results show that after the energy-saving strategy is improved,the theoretical PUE can reach 1.34 under the operation scheme,while the PUE value of the conventional scheme operation is 1.48.The scheme proposed in this paper is highly feasible and can even reach a lower PUE value under permitted conditions.
