摘　　要：针对广州珠江新城某超高层建筑的内循环式双层幕墙结构,采用门窗幕墙热工模拟计算系列软件,分别对封闭及通风状态下的内、外层传热系数、遮阳系数以及可见光透射比等参数进行模拟计算,同时采用CFD技术对典型工况下内置遮阳百叶的遮阳效果进行模拟计算,将分析研究成果直接用于指导该项目双层幕墙的热工设计及建筑节能设计,对类似工程提供参考。Thermal performance simulated investigation was carried out for a supper tall-building with internal circulation curtain wall at Zhu Jiang New City of Guangzhou. Simulated computation was carried out for heat transmission coefficient,shading coefficient and trans- mission adopted the software of thermal simulating for curtain wall and window,ere,which included close and open status,respectively. At the meantime, the shading effective of interior shading shutter on typical work conditions was simulated using CFD simulation technique. Through comprehensive analysis,the research results of this paper instruct the thermal design of double curtain wall of this tall building directly,and have a lot of benefits for other practice projects.
