Description

高效节能隔热窗 技术领域
本发明涉及一种用于闭合开口的窗扇、门扇或类似构件,特别是涉及一种高效节能隔热窗。
背景技术
我国的建筑外窗节能技术和要求正在逐步提高,以北京为例,从2012年起,国家规范要求的建筑外窗传热系数已经从过去的2.8W/(m2K)降低到了2.0W/(m2K)。即便如此,我国与欧美发达国家的差距仍然十分明显,德国1994年的建筑外窗传热系数已经达到了1.8W/(m2K),2012年更是进一步降低到了1.3W/(m2K)。根据住建部建筑门窗节能标识的统计,2013年中,相关的门窗节能标识产品共1787个,但90%以上都是传热系数为2.0-3.2W/(m2K)的产品,低于2.0W/(m2K)的门窗产品仍以国外产品为主。因此,如何进一步降低传热系数、改善国产门窗节能效果,成了业内亟待解决的问题。
以断桥铝窗为例,在确定了基本建筑外窗窗型后,为降低整窗的传热系数Ut,现有的技术方案有:1)采用三玻两腔中空玻璃或真空中空玻璃;2)采用高性能的双银或三银Low-e玻璃;3)将中空玻璃中传统的铝合金间隔条改为暖边间隔条;4)在中空玻璃的中空腔内填充惰性气体。
从工程设计角度来看,上述技术方案分别存在以下不足:
方案1):窗玻璃造价大幅增加。目前窗玻璃的配置大都为双玻中空玻璃,其厚度一般为22mm、24mm、28mm等;三玻两腔中空玻璃的厚度一般为33mm、36mm、39mm等;真空中空玻璃的厚度一般为27mm、35mm等,现有的窗框型材断面需要修改以适应窗玻璃的厚度变化,这就使得现有窗框型材的适应性降低,大幅增加了型材用量以及的型材开模的成本。
方案3):大量使用暖边间隔条,由于暖边间隔条的技术含量较高,基本依赖进口,大量使用不但采购环节复杂,周期长,影响施工进度,而且成本也高。同时暖边间隔条的使用只能部分降低玻璃传热的边部效应,因此,对整窗的传热系数下降的贡献率较低。
方案4):中空玻璃填充惰性气体存在泄露问题,而且实际检测传热系数的方法也较为复杂、实际操作难度较大,同时,行业内对中空玻璃填充惰性气体后的耐久性一直存疑,不适合大面积推广使用。
方案2):如图1所示,现有的采用双玻双银Low-e中空玻璃的铝窗,包括窗玻璃10、室 外窗框20、室内窗框30、隔热条40、室外胶条50、室内胶条60。其中窗玻璃10通过室外胶条50和室内胶条60被固定在室外窗框20和室内窗框30之间,室外窗框20和室内窗框30之间通过隔热条40连接。该铝窗主要依靠隔热条40(解决型材的隔热)和中空Low-e玻璃(解决窗玻璃10的隔热)解决热传导问题。经美国LBNL的Window7,Therm7热工分析软件分析,采用双玻双银Low-e中空玻璃后,整窗传热系数为2.1W/(m2K)。可见,本方案采用了双玻双银Low-e玻璃,在一定程度上降低了玻璃窗的传热系数,但对改善整窗隔热效果的贡献仍不理想。这是因为,根据理论研究和对大量不同配置的窗系统进行热工计算后发现,窗框的面积虽然只占整窗的20%-25%,但通过窗框的传热量却占整窗的50%以上,而窗玻璃的面积虽然占整窗的75%-80%,传热量却只占整窗的50%以下。因此,该方案在提高了窗玻璃的隔热性能后,被阻挡的大部分热量会经窗玻璃边部及其与窗框之间的缝隙传递,导致整窗传热系数下降不明显,并可能出现窗框表面结露的现象,而且整窗传热系数也不能满足日益严苛的节能设计要求。

综上所述,本发明的高效节能隔热窗,由于在窗玻璃、室外窗框和室内窗框之间设置了导热系数较低(一般不高于0.021W/(m·K))的气凝胶隔热毯制成的密封条,该密封条的隔热性能比空气的导热系数还低,相比传统的门窗隔热断桥材料,其材料导热系数更是降低了10倍以上,传热系数(即整窗U值)可达到1.7-1.8W/(m2K),较现有技术的双玻铝窗下降了15%,显著增强了节能效果。采用三玻Low-e中空玻璃时,整窗传热系数甚至可降至1.5-1.6W/(m2K),隔热效果突出。而且,本密封条使用时不需改变现有窗的构造,既不影响其水密性、气密性和结构变形性能,又大幅提高了整窗的隔热性能,确保窗框室内侧不产生结露问题,大大减少了高节能建筑外窗的综合成本。同时,气凝胶隔热毯便于安装,能很好地适应窗玻璃、室外窗框和室内窗框之间的复杂截面形状,形成同一材质且连续、整体的隔热条。另外,由于气凝胶隔热毯是燃烧性能A级的无机隔热材料,故还可避免使用有机隔热材料燃烧性能差的问题。还有,采用密封条后,暖边间隔条可在必要的时候选用,一定程度上降低了其使用几率,有利于缩短工期、节省开支。
以上所述的实施例仅仅是对本发明的优选实施方式进行描述,并非对本发明的范围进行限定,在不脱离本发明设计精神的前提下,本领域普通技术人员对本发明的技术方案作出的各种变形和改进,均应落入本发明权利要求书确定的保护范围内。
工业实用性
本发明节能隔热窗结构简单、施工便捷、成本低,并且能大幅度提高整窗节能效果,整窗传热系数较现有技术的双玻铝窗下降了15%。
