摘　　要：相比传统中庭,超高层建筑的中庭具有竖直温度分层明显,烟囱效应和渗透风量显著等特点,进而造成中庭环境热舒适性不佳,建筑空调能耗偏高等问题。本文结合具体超高层项目,实测中庭温度分布,并结合CFD进行室内热环境模拟。旨在分析分层空调送风角度、穿梭电梯渗透风量等对超高层中庭热环境的影响,并为超高中庭空调系统设计提供参考。Compared with the traditional atrium,an atrium of the high-rise building has some unique features,which include an obvious vertical temperature stratification,chimney effect,massive infiltration air and so on.Combined with a super high-rise building,this paper studied on the thermal environment,by measuring the temperature distribution of atrium,and simulating indoor thermal environment with CFD simulation.With the aims to analyze the influence of air supply angle of stratified air conditioning and infiltration air volume of shuttle elevator on the thermal environment,it provides references for the design of air conditioning system of super high-rise atrium.
