既有数据中心机房节能改造方案研究

Research on Energy-saving Renovation Plan for Existing Data Center rooms

为满足当前绿色高质量发展要求,需要对老旧的既有数据中心机房进行节能改造,在中国移动信息港一号地数据中心改造项目中针对原精密空调送风距离较远、易出现局部热点等问题,进行机房运行状态综合评估,并采用计算流体力学(CFD)模拟软件6SigmaRoom对三种拟采用的节能改造方案进行模拟研究,通过分析气流组织情况和空调节能效果,选取顶置式热管空调+封闭冷通道的方案对机房进行改造。通过模拟改造后144h内的耗电量,计算得出空调末端PUE因子降至0.014,节电率约为92%。本文研究结果可为既有数据中心机房节能改造提供参考。

In order to meet the current requirements for green and high-quality development,it is necessary to carry out energy-saving renovation on the old existing data center computer room.In the China Mobile Information Port No.1 Data Center Renovation Project,a comprehensive evaluation of the operating status of the computer room was carried out to address issues such as the long distance of the original precision air conditioning supply and the susceptibility to local hotspots.Computational Fluid Dynamics(CFD)simulation software 6SigmaRoom was used to simulate and study three energy-saving renovation schemes.By analyzing the air flow organization and energy-saving effects of the air conditioning,the top mounted heat pipe air conditioning+enclosed cold channel scheme was selected to renovate the computer room.By simulating the power consumption within 144 hours after renovation,it was calculated that the PUE factor at the end of the air conditioning system decreased to 0.014,resulting in a power saving rate of approximately 92%.The research results of this article can provide reference for energy-saving transformation in existing data center computer rooms.
