摘要
采用Flixo热桥分析软件模拟超低能耗建筑外窗外挂安装和内嵌安装的线性热桥、内表面温度,并分析内嵌安装方式的不同优化处理措施。发现外窗内嵌安装方式采取优化措施后完全可满足超低能耗建筑要求。内嵌安装时,窗侧口(顶部)线性热桥略有增加,但影响不大,满足超低能耗建筑的要求,可不进行优化处理;底部应采用高度不小于40mm的防腐木或同等保温性能附框进行热桥处理。
This paper uses Flixo thermal bridge analysis software to simulate the installationof external windows in ultra-low energy buildings,the different optimization measures of embeddedinstallation are analyzed.It is found that the internal embedding installation of pxterior windows canfully meet the requirements of ultra-low energy buildings after taking optimization measures.During theinternal embedding installation,the window side opening(top)line thermal bridge is slightly increased,but it has little influence,so it can meet the requirements of ultra-low energy buildings,so it needsnot be optimized;the bottom should be treated with anti-corrosion wood with a height of not less than40mm or enclosure with the same thermal insulation performance.
