自然通风导向下的大空间建筑腔体植入研究

Research on cavity implantation of large space building under the guidance of natural ventilation

在腔体布局类型解析的基础上,结合大空间建筑的空间组合特征和自然通风难点,提出周边式腔体的并置式植入、内置式腔体的嵌入式植入及复合式腔体的协同式植入三种模式。结合典型案例展开CFD数值模拟,探索大空间建筑在自然对流状态下内部气流组织规律和分布特征,验证三种模式在自然通风组织中的有效性,为方案阶段的腔体导控设计提供参考。

Based on the analysis of cavity layout, three modes including peripheral, internal and composite were proposed with space combination features and natural ventilation difficulties of large space buildings. Combined with the typical case, CFD numerical simulation was carried out to explore the air distribution characteristics in the large space under the state of natural convection. The effectiveness of the three cavity implantation modes was verifed in the natural ventilation of large space buildings, which could provide reference for the cavity scheme design.
