近年来我国国内数据中心的发展蒸蒸日上,数据中心的功率密度越来越高。由于数据中心内IT负载的电能最终都将转化为热能,所以为维持数据中心正常运行的空调解决方案就变得至关重要。本文从数据中心的机房内制冷架构、空调节能模式和冷热通道遏制三个角度对数据中心空调解决方案的制冷效果、投资节能以及机房系统升级三方面进行分析,找出使机房空调解决方案最优化的方法途径。 In recent years, the development of China’s domestic data center is booming, and the data center’s power density is getting higher and higher. As the power of the IT load in the data center will eventually be converted to heat, air-conditioning solutions to keep the data center up and running will become critical. This article analyzes the cooling effect, investment saving and room system upgrade of data center air conditioning solutions from three aspects: the cooling architecture in the data center, the energy-saving mode of air-conditioning and the containment of hot and cold aisles, Optimized ways and means.
