摘　　要：由于气流组织不合理导致数据机房存在局部过热以及冷风浪费等问题。对设备布局变化的多种机房模型进行了数值模拟,获得了多种不同设备布局下机房的速度场、温度场以及典型平面的平均温度。结果表明,机房内设备的不同布局结构会影响机房内的气流组织分布,对于不同规模的数据机房都存在较优的设备布局,能够实现数据机房的节能。具体来说,空调斜对放置与机柜间距适当增大相结合最佳。The irrational air distribution of data room will cause the local overheating and the waste of cold wind. Various computer models of equipment layout are simulated to obtain velocity fields, temperature .fields and the average temperature of the typical plane that under different equipment layouts. The results show that the computer room equipment in different layout structures will affect the room air distribution; a better equipment layout to various data rooms of different size can realize the energy efficiency. To be specific, inclining the air conditioning and appropriate spacing increases between cabinets are better choice.
