【摘要】：为研究送风温度变化对数据中心热环境的影响,在分析数据中心空调系统负荷特性和能耗现状的基础上,以南京某小型数据中心工程实例为研究对象,采用数据中心专用CFD模拟软件对其气流组织进行了数值模拟,分析了该机房冷量利用情况。结果表明,送风温度变化会对气流组织产生一定的影响,送风温度提高,机柜平均出风温度提高,部分机柜存在冷量利用不充分的情况;距地面1.5m、3m平面位置及主要衡量立面温度均有不同程度的提高,增幅在3.8%—12.9%之间,气流组织受到一定的影响。综合分析得出送风温度在13℃热环境较好,更有利于冷量的充分利用。
[Abstract]:In order to study the influence of air temperature change on the thermal environment of data center, based on the analysis of load characteristics and energy consumption of air conditioning system in data center, a small data center project in Nanjing is taken as the research object. The air distribution was simulated by using the special CFD software of data center, and the utilization of cold volume in the room was analyzed. The results show that the air distribution will be influenced by the change of air temperature, and the air temperature will be increased. The average outlet air temperature of the cabinets is increased, and some of the cabinets have insufficient utilization of the cold capacity, and the horizontal position of 1.5mm3 from the ground and the main measuring elevation temperatures have increased to varying degrees, with an increase of between 3.8% and 12.9%. The comprehensive analysis shows that the air supply temperature is better at 13 鈩，
