【摘要】 考虑中庭顶部采用大面积天窗对室内热环境产生较大影响，以河北省某展览馆内中庭为例，利用Fluent软件对中庭建立物理、数学模型，进行气流组织模拟，分析不同断面下冬、夏季工况的温度场和速度场，进而评估设计条件下的室内热环境。模拟结果表明：合理分配天窗冷负荷比例、天窗设置遮阳设施、局部设置地板辐射供暖系统可有效改善中庭人员活动区域的热舒适性。更多还原

【Abstract】 Considering that the large-area skylight on the top of the atrium has a great impact on the indoor thermal environment,this paper takes the atrium of an exhibition hall in Hebei as an example,establishes physical and mathematical models of Fluent software and simulates the air distribution to analyze the temperature field and velocity field in winter and summer conditions under different sections of the atrium,then evaluates the indoor thermal environment under the design conditions. The simulation results show that the thermal comfort of the atrium can be effectively improved by reasonably distributing the cooling load ratio of the skylight,setting shading facilities for the skylight,and locally setting the floor radiant heating system.更多还原
