摘要
以轨道交通控制中心数据机房为研究对象,给出了数据机房的空调负荷特征,采用三维数值模拟软件Airpak,建立机房的CFD模型,针对低、中、高三种空调负荷强度下,给出采用下送上回、冷通道下送上回、侧送侧回和上送上回四种不同空调送风形式时,机房内的气流组织分布特性、温度场和流场进行模拟分析,提出不同送风形式的适用性,用于指导工程设计。
Taking the railway traffic control center data room as the research subjects,the cooling load of different room is gained,by utilizing the three-dimensional numerical simulation software,the CFD model of data room is established to simulate the air distribution,the temperature field and the flow field of data room under three kinds of air conditioning load intensity and four different air supply forms are simulated.The analysis of the practicality of different air supply forms is given to guide the engineering design.
