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 data center thermal environment is the basis for ensuring the stable operation of communication equipment such as servers and extending the service life. Among them, it is important to evaluate the local overheating reasonably to reduce the energy consumption ratio of air conditioning system. Based on reviewing the existing evaluation index of thermal environment in evaluation data center, this paper presents a local overheating index, and establishes a typical data center model for numerical simulation. Compared with the existing indicators, it is concluded that local overheating index Environment and rack hot spots in the local more advantages, better energy conservation in the data center to make recommendations for optimization.
