摘　　要：研究旨在通过对寒地某高校图书馆中庭空间的实地测量与模拟,解析自然通风工况下,中庭空间形态对其热环境的影响,为寒地高校图书馆中庭设计提供参考。结果表明:自然通风工况下,通过在中庭空间中增设横向平台能显著降低平台下部区域的日照得热,缓解上部区域热气流汇聚程度,改善中庭内部热舒适水平,但也会削弱烟囱效应对周边连通空间热环境的改善作用。Based on field measurement and numerical simulation of a complex university library atrium in the cold region under natural ventilation,this paper analyzes the influence of atrium form on its thermal environment and provides reference for the atrium design of university library in the cold region.The results indicates that under the condition of natural ventilation,horizontal platform in the atrium space can significantly reduce the solar heat gain in the lower part of the platform,alleviate the convergence degree of hot airflow in the upper area and improve the thermal comfort level in the atrium space.However,it will also weaken the chimney effect of atrium,and reduce the thermal comfort level of the surrounding space.
