某博物馆反拱屋面展厅的气流组织设计与模拟分析

Airflow organization design and simulation analysis of a museum’s inverted arch roof exhibition hall

博物馆的展厅空间复杂,在设计时需对其气流组织及舒适性等加以模拟预测,必要时对其气流组织的设计方案进行比选。笔者以河南省洛阳市某博物馆一个展厅的气流组织为研究对象,设计了侧喷下回、地送上回两种送回风形式,并对其冬夏季工况分别运用气流组织CFD模拟软件,模拟现场气流组织形式,比较两个方案的温度场及速度场,最终结果表明,地送上回的送回风形式在制冷工况和制热工况均略优于侧喷下回,尤其是冬季制热工况尤为明显,运用该送回风形式在人员活动区域的热舒适性得到显著提高。

The exhibition hall space of the museum is extremely complicated.When designing,the airflow organization and comfort are simulated and predicted,and the airflow organization design schemes are compared and selected when necessary.In this study,the airflow organization in an exhibition hall of a museum in Luoyang was designed,and two return air modes were designed,namely,side spray,bottom return and ground return,and the air flow organization CFD simulation software was used to simulate the scene in winter and summer.The air flow organization form,comparing the temperature field and velocity field of the two schemes,the final result shows that the return air form of the ground to the upper return is slightly better than the side spray and the lower return in the cooling conditions and heating conditions,especially in winter heating conditions.So that the thermal comfort of the personnel with the return air form in the personnel activity area has been significantly improved,providing a reference for the air conditioning design of the same type of building.Significantly improved.
