摘要
对杭州市某建筑的外呼吸式双层通风幕墙进行了热工性能的模拟分析,依据JGJT151-2008,采用幕墙门窗热工性能计算软件对内外层幕墙的传热系数、遮阳系数以及可见光透射比等参数进行模拟计算,并计算冬季封闭及夏季通风状态下的传热系数,采用CFD技术对双层通风幕墙空腔内的速度场和温度场进行模拟分析。本研究成果直接指导了该项目双层幕墙的热工设计,且对类似工程具有很好的借鉴价值。
Simulates and analyses the thermal performance for the external respiration circulation double skin facade with interior sunshade blind of a building at Hangzhou City. Simulation calculation was carried out for heat transfer coefficient, shading coefficient and visible transmittance adopted the software of thermal simulating for curtain wall and window for interior and external curtain wall according as JGJ/T 151-2008. Calculation the double skin facade heat transfer coefficient for close status in winter and open status in summer. Simulates and analyses the velocity and temperature fields for double skin facade cavity using CFD simulation technique,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.
