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。

本发明高效节能隔热窗，其中所述断面呈“L”形的密封条由四条首尾相接的“L”形子密封条组成，其中一对端头封口的“L”形子密封条分别包覆窗玻璃的两个相对的玻璃边及两个 玻璃角，另一对端头开口的“L”形子密封条包覆窗玻璃的其余两个相对的玻璃边，所述断面呈“L”形的密封条的一个边包覆在所述窗玻璃的室外面上。

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％。
