| 阶梯围绕式边庭作为一种新型的共享空间形式,在国内应用与研究较少,本文以夏热冬冷地区某高校图书馆阶梯围绕式边庭为例,通过数值模拟与实测的方法探讨阶梯围绕式边庭在过渡季节自然通风与热环境特性。对边庭各楼层和在不同时间段内的室内温度分布以及空气流动状态分析,阶梯围绕式空间形式有助于提高自然通风效率和空气质量,但风压和热压以及边庭的几何形态会对通风路径产生影响,导致室内温度分布不均。为了优化温度分布不均的问题,在边庭设置导流板,改善了空气流动路径,使室内温度分布更加均匀,提升了自然通风的整体效果和室内热舒适性。通过本文的研究,可以为阶梯围绕式边庭提供设计与应用参考。 |
| 英文摘要: |
| As a new form of shared space, the stepped design surrounding the side court has been less applied and studied in China. This paper takes the stepped side court of a university library in a hot-summer and cold-winter region as an example, exploring the characteristics of natural ventilation and the thermal environment in this space during the transition season through numerical simulation and actual measurement. After analyzing the distribution of indoor temperature and airflow on each floor and at different times, it was found that the stepped-surrounding spatial form improves natural ventilation efficiency and air quality. However, wind and thermal pressures, as well as the geometric shape of the side court, affect the ventilation paths, leading to uneven indoor temperature distribution. To optimize the uneven temperature distribution, deflector plates were installed to improve the airflow path, making the indoor temperature more uniform. This enhances the overall effect of natural ventilation and improves indoor thermal comfort. The research in this paper can provide design and application references for stepped side courts. |
