摘要
结合寒冷地区的自然条件,对数据中心空调系统原理及架构进行介绍。以某数据中心为研究对象,从系统优缺点、初投资、运行费用、PUE(电能使用效率)等方面进行分析。结果表明,水冷式空调系统初投资及10年运营总成本优势明显,建议水资源相对丰富地区优先采用,通过附加间接蒸发冷却技术,PUE可降低至1.3以下。
Based on the natural conditions in the cold region,the principle and architecture of air-conditioning systems of data center are introduced.Taking one data center as the research subject,the analysis is conducted from the advantages&disadvantages of system,initial investment,operating cost,PUE(power usage effectiveness).The results show that the water-cooled air-conditioning system has obvious advantages in the aspects of the initial investment and the total operating cost of 10 years,and it is suggested that the application should be prioritized in areas with relatively abundant water resources.With the addition of indirect evaporative cooling technology,the PUE can be reduced to less than 1.3.
