典型数据机房热环境分析及气流组织优化
Thermal environment analysis and air distribution optimization for a typical data room
摘要：
介绍了数据机房的热环境评价指标。以某典型数据机房为研究对象，对其热环境进行了现场实测和CFD模拟，发现存在冷量浪费的现象。在原有送回风方案的基础上分别采用在冷通道侧机架顶部加装隔板和部分封闭冷通道两种方案改善机房气流组织。CFD模拟结果显示，两种优化方案对提高冷量利用效率均有效，其中冷通道部分封闭的方式能将冷气流更大限度地局限于冷通道内，能更有效地提高机房空调冷量利用效率。
Abstract：
Presents the evaluation indices of thermal environment in data rooms. Taking a typical data room as example, through field test and CFD simulation of the thermal environment, finds cooling waste. Two strategies of adding vertical partitions above the rack on cold aisle side and partly enclosing cold aisles are adopted to improve air distribution based on the original configuration. The results of CFD simulation indicate that the two strategies are both effective, while the latter limits the cold air in the cold aisles to a larger extent, and provides enough cold air to the servers. Therefore, it gets better performance in cooling efficiency improvement.
