摘要
针对数据中心主机房空调常规采用的风管上送风、地板下送风等气流组织形式的局限性,设计一种冷墙侧送风、密闭热通道上回风的气流组织形式,并对其进行CFD模拟分析,结果显示冷通道温度处于20~21℃之间,热通道温度处于31~33℃之间,满足数据中心主机房工作温度要求。
In view of the limitations of commonly used air distribution types for the computer room air-conditioning in data center,such as upper air supply of air duct,downside air supply of floor and so on,a new way of air distribution realized through lateral air supply of cold wall and upper air return by hot aisle containment(HAC)is analyzed.And corresponding simulation analysis is conducted by CFD.The results show that the temperature of cold aisle is basically 20-21℃,and the temperature of hot aisle is basically 31-33℃,which meet the requirements of the working temperature of computer room in data center.
