基于自然通风的中小学教室室内热环境优化研究——以沈丘东城实验学校项目为例

Research on Indoor Thermal Environment Optimization of Primary and Middle School Classrooms based on Natural Ventilation:Taking Shenqiu Dongcheng Experimental School Project as an Example

自然通风是建筑运营中的重要一环,针对中小学建筑使用群体年龄小、数量大、建筑换气频率高的特点,自然通风在中小学建筑中尤为关键,这不仅是绿色建筑理念下被动式技术的体现,也是维持中小学教室室内舒适环境的措施。文章以沈丘县某中小学教室为研究对象,结合该地区气候条件,探究在不同开窗面积下教室室内的通风情况,以及导风板对室内通风效果的影响,并运用CFD软件对教室的自然通风进行模拟优化,对室内热环境进行评价。希望为类似教学建筑室内热环境优化提供理论方法和对比分析。

Natural ventilation is an important part of building operation,in view of the small age,large number and high frequency of building ventilation in primary and secondary school buildings,natural ventilation is particularly critical in primary and secondary school buildings,which is not only the embodiment of passive technology under the concept of green buildings,but also a measure to maintain a comfortable indoor environment in primary and secondary school classrooms.Taking a primary and secondary school classroom in Shenqiu County as the research object,combined with the climatic conditions in the area,this paper explores the ventilation situation of the classroom under different window areas,as well as the influence of the air guide plate on the indoor ventilation effect,and uses CFD software to simulate and optimize the natural ventilation of the classroom and evaluate the indoor thermal environment.It is hoped to provide theoretical methods and comparative analysis for the optimization of indoor thermal environment in similar teaching buildings.
