某大法庭室内气流组织模拟

Simulation of Indoor Airflow Organization in a Certain Large Court

为了快速预测大空间建筑气流组织及热舒适性是否满足设计要求,本文采用数值模拟的方法对某中级人民法院大法庭的夏季室内温度、风速等重要参数进行模拟,并采用PMV和PPD指标对室内热舒适性进行评价。模拟结果表明,在1.2m高截面处(人员静坐高度)的平均风速小于0.3m/s,且分布均匀,平均温度为24.8℃,PMV为0.08~0.32,PPD为6.0%,室内温度和风速等参数满足设计要求,热舒适性较好。本文结果对大空间建筑的气流组织和热舒适性研究具有一定参考价值,可为相关设计提供参考依据。

In order to quickly predict the airflow organization and thermal comfort of a large space building,numerical simulation methods are used to simulate important parameters such as summer indoor temperature and wind speed of a large court in an intermediate people's court,and indoor thermal comfort is evaluated with PMV and PPD indicators.The simulation results show that the average wind speed at a height of 1.2 meters(personnel sitting height)is less than 0.3m/sand uniform,the average temperature is 24.8 C,the PMV value is 0.08~0.32,and the PPD value is 6.0%in summer design conditions.The indoor temperature,wind speed and other parameters basically meet the design requirements,and the thermal comfort is good.The results of this paper are useful for the study of air flow organization and thermal comfort in large space buildings,and can provide reference basis for related design.
