数据中心热环境的局部过热指数分析

Analysis of Local Overheating Index for Thermal Environment in Data Center

数据中心热环境是保障服务器等通信设备稳定运行和延长使用寿命的基础。其中,合理评价局部过热现象对降低空调系统能耗比有重要意义。本文在回顾现有的评价数据中心热环境评价的指标基础上提出局部过热指数,并通过建立一个典型数据中心模型进行数值模拟,与现有指标进行分析对比,得出局部过热指数对体现机房热环境及机架的局部热点方面更有优势,更好对数据中心的节能改造提出优化建议。

The thermal environment in the data center has a significant effect on the stable operation of communication equipment and prolonging the service life of the servers. It is important to evaluate local overheating reaction reasonably for reducing the energy consumption of air-conditioning system. Based on the review of current research on evaluating thermal environment in the data center, this paper defines Local Overheating Index and compares it with the existing index by building a simulation model of a typical data center. Local Overheat Index has more advantages in reflecting the thermal environment in the data center and local hot spot of racks, and giving some suggestions for energy utilization of the data center.
