摘　　要：本文主要研究了某数据中心对机房热工环境的影响,通过采用CFD软件建立起仿真模型进行了数据模拟,比较了两种列间空调的布局方式对室内环境的温度场及速度场的影响,并进行能耗分析,得出以下结论:当列间空调在机柜间均匀布置时,冷量未充分利用,从而导致制冷系统的效率降低;当列间空调采用列头布置的方式时,机柜背面出风口处的温度分布较为均匀,且服务器、机柜及房间温度都有所下降,制冷效率提高。This paper mainly studied the influence of the thermal environment of computer room one data center.It established a simulation model by using CFD software to compare the temperature field,velocity field,and energy consumption of two columns between the layout of air conditioning.The following conclusions:when the air conditioner evenly between cabinet layout between columns,did not make full use of the cooling capacity,resulting in lowering the efficiency of refrigeration system;When the air conditioner between columns is arranged in the way of column head,the temperature distribution of the air outlet on the back of the cabinet is relatively uniform,and the temperature of the server,the cabinet and the room all decreases,and the refrigeration efficiency is improved.
