摘要
数据中心高能耗问题是各国政府和产业界的关注焦点。本文定义了数据中心的能耗结构构成,深入分析了数据中心主要耗能环节。在此基础上,分别从供电系统、制冷系统两大主要耗能环节入手,系统阐述了市电直供、自然冷却、近端制冷、液冷等最新节能技术的发展趋势。
This paper introduced the structrue of energy consumption in data center and analyzed the major components which consumped the energy.Then this paper described the newest development tendency of energy conservation of Power system and cooling system,including direct supply of city electricity,near-end cooling,free cooling and liquid cooling,etc.
