摘要
研究旨在通过模拟分析和优化措施,改善四川水利职业技术学院11号宿舍楼的自然通风效果,提升室内空气质量。以该宿舍楼为对象,利用CFD技术模拟室内自然通风情况,分析通风现状,并提出优化措施,包括设置学生活动区域形成文丘里管、改变空间模式、更换窗的开启方式等,并对优化后的通风效果进行模拟分析。优化前背风侧宿舍风速分布不均,部分区域风速低至0.12 m/s,换气次数仅1次/h。优化后,中部偏右区域宿舍风速显著提升至0.35~0.45 m/s,换气次数达到2次/h;更换窗的开启方式后,背风面宿舍风速提升至0.3~0.4 m/s,换气次数增加至3次/h。通过优化措施,可显著改善宿舍楼的自然通风效果,提高室内空气质量,为类似建筑的自然通风优化提供参考。但研究存在边界条件简化、学生动态行为考虑不足等局限,未来可结合智能控制系统进一步优化。
The study aims to improve the natural ventilation effect of Building No.11 in Sichuan Water Conservancy Vocational College and enhance indoor air quality through simulation analysis and optimization measures.Taking this dormitory building as the research object,the study uses CFD technology to simulate the indoor natural ventilation situation,analyzes the current ventilation status,and proposes optimization measures,including setting up student activity areas to form a venturi tube,changing the spatial layout,and replacing the window opening methods.The ventilation effects after optimization are also simulated and analyzed.Before optimization,the wind speed distribution on the leeward side of the dormitory was uneven,with some areas having a wind speed as low as 0.12 m/s and an air change rate of only 1 time/h.After optimization,the wind speed in the dormitory area to the middle right significantly increased to 0.35~0.45 m/s,and the air change rate reached 2 times/h.After changing the window opening method,the wind speed on the leeward side of the dormitory increased to 0.3~0.4 m/s,and the air change rate increased to 3 times/h.The optimization measures can significantly improve the natural ventilation effect of the dormitory building and enhance indoor air quality,providing a reference for the natural ventilation optimization of similar buildings.However,the study has limitations such as the simplification of boundary conditions and insufficient consideration of students'dynamic behavior.Future research can further optimize the process by combining intelligent control systems.
