金堂县特殊教育学校中庭自然通风系统设计研究

Research on the Design of Natural Ventilation System in the Atrium of Special Education School inJintang County

中庭顶部设置玻璃顶盖,可以避免雨雪天气对人员活动的限制,但顶盖同时也会影响中庭内空气流通。论文对中庭风环境进行CFD(计算流体动力学)模拟分析,模拟中庭在不同的高度和通风口工况下其风速分布和通风换气量,并借助上述指标对其热压通风效果进行评价,确定适宜的中庭高度和通风口。

A glass top cover is installed on the top of the atrium to avoid restrictions on personnel movement in rainy and snowy weather,but the top cover also affects the air circulation inside the atrium.This article conducts CFD(Computational Fluid Dynamics)simulation analysis on the atrium wind environment,simulating the wind speed distribution and ventilation volume of the atrium under different heights and ventilation conditions.Using the above indicators,the thermal pressure ventilation effect is evaluated to determine the appropriate atrium height and ventilation.
