山西农业大学小广场环境的微气候模拟分析

Analysis on Microclimate Simulation of Small Square of Shanxi Agricultural University

山西农业大学小广场是师生游玩、休憩的重要空间节点,为研究它的微气候以及舒适性,通过Envi-met软件对此空间的小气候进行模拟,选用了空气温度、风速,结合热舒适性分析了此环境。结果表明:小广场的整体温度呈上升到下降的趋势,风速呈先增大后减小在增大的趋势。硬质区域从8∶00到23∶00,环境温度逐渐增大,15∶00左右到达顶峰,之后又逐渐降低。风速从10∶00左右基本呈下降趋势,19∶00之后有缓慢的回升。人体的舒适度在10∶00-20∶00的时间段内基本呈热-炎热-热的状态。小广场环境温度高的时候,风速反而下降,舒适度不合适。

The small square in Shanxi Agricultural University for teachers and students ,is open space node and important for the study of its microclimate and comfort ,through Envi‐met the microclimate space ,the choice of air temperature ,wind speed ,combined with thermal comfort analysis of the environment were simulated .The results showed that the overall temperature of the small square was rising to a downward trend ,the wind speed increase first and then decreases ,at last increasing trend .From 8∶00 to 23∶00 ,the ambient temperature in‐creased ,around 15∶00 reached the peak ,the gradually reduced .Winds from the morning around 10∶00 substan‐tially decreased ,after 19∶00 there was a slow recovery in the hard area .Human comfort in 10∶00‐20∶00 was hot‐hot‐hot state .Small square ambient temperature was high ,but wind speed ,comfort inappropriate de‐creased .
