送风高度对高大空间玻璃幕墙建筑室内气流组织的影响

INFLUENCE OF AIR SUPPLY HEIGHT ON INDOOR AIR DISTRIBUTION OF GLASS CURTAIN WALL BUILDING IN LARGE SPACE

结合河北廊坊某高大空间玻璃幕墙建筑,采用CFD技术,对3种不同送风高度下玻璃幕墙建筑室内气流组织进行了模拟分析,其中3种送风高度分别是h=8 m、h=6 m、h=4 m,以此来研究送风高度对高大空间玻璃幕墙建筑室内气流组织的影响。结果表明:采用h=6 m送风高度可较显著地改善空间内气流速度分布和人员活动区域温度分布的均匀性,提升人体热舒适度。

Combined with Hebei Langfang glass curtain wall building,CFD technology is used to simulate and analyze the indoor air distribution of glass curtain wall buildings under three different air supply heights,among which the three air supply heights are h=8 m,h=6 m and h=4 m respectively,so as to study the influence of air supply height on the indoor air distribution of glass curtain wall buildings in large space.The results show that using h=6 m air supply height can significantly improve the uniformity of air velocity distribution in space and temperature distribution in personnel activity area,and improve the thermal comfort of human body.
