Description
技术领域
本发明属于建筑窗户技术领域,特别涉及一种集热保温隔声一体化窗户及其控制方法。
背景技术
在高原地区,白天太阳辐照强烈,夜晚气温寒冷。传统窗户由于围护结构热工参数固定不变,其太阳总透射比和传热系数固定,如图1所示,故传统窗户无法解决白天太阳得热要求的太阳总透射比大和夜间防止失热希望的传热系数小的矛盾,造成实际工程项目应用效果欠佳。同时,对于平原等挨近马路的建筑,在夜晚睡觉时常受到噪声控扰,为此常通过设置独立的两道窗户解决隔声问题,一方面造价高昂,另一方面对建筑窗台设置提出高的要求。
发明内容
本发明的目的在于:针对上述存在的问题,提供一种能够实现白天太阳总透射比大且夜晚实现传热系数小的性能参数,而且在实现噪声可控的同时,方便窗户安装,并降低造价的集热保温隔声一体化窗户及其控制方法。
为实现上述目的,本发明采用以下技术方案:一种集热保温隔声一体化窗户,包括窗框,其特征在于:在一个窗框上集成了内窗和外窗,所述内窗和外窗均能全部开启或部分开启,所述内窗采用传热系数小且隔声性能好的玻璃结构,所述外窗采用太阳总透射比大的玻璃结构。
本发明所述的集热保温隔声一体化窗户,其所述内窗由内开活动窗扇组成,所述内开活动窗扇的边缘部分别通过窗扇连接件与窗框转动连接,通过内开活动窗扇能将内窗全部开启;所述外窗由固定窗扇和外开活动窗扇组成,所述外开活动窗扇通过窗扇连接件与窗框转动连接,通过外开活动窗扇能将外窗部分开启。
本发明所述的集热保温隔声一体化窗户,其所述外开活动窗扇采用上悬活动开启结构。
本发明所述的集热保温隔声一体化窗户,其所述内窗为中空双层玻璃结构,所述外窗为单层玻璃结构。
本发明所述的集热保温隔声一体化窗户的控制方法,其特征在于:对于应用于太阳能热利用的情况,当白天太阳升起,辐照量较大,太阳辐射得热大于外窗对流换热失热时,即IT(S,γf)·g>h·(tn-tw),开启内窗,通过外窗向室内辐射得热;当下午太阳落下或阴天工况,辐照量较小,太阳辐射得热小于外窗对流换热失热时,即IT(S,γf)·g<h·(tn-tw),关闭内窗,通过增加对流换热热阻,对室内进行保温;
式中:IT(S,γf)为窗户表面总太阳辐照,W/m2;g为太阳总透射比,h为外窗表面对流换热系数,W/(m2·K);tn为室内干球温度,K;tw室外干球温度,K;
对于应用于隔声的场合,当室外噪声对室内的影响超过室内噪声要求时,关闭内窗,隔绝噪音;当室外噪声对室内的影响未超过室内噪声要求时,可打开或者继续关闭内窗,进行通风或保温隔热。
本发明通过在窗框上采用内外窗的结构设计,并采用不同性能参数的玻璃结构,从而有效解决现有窗户所期望的白天太阳总透射比大而夜晚传热系数小的矛盾问题,而且还能在实现噪声可控的同时,方便窗户安装,并降低造价。

具体实施方式
下面结合附图,对本发明作详细的说明。
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
如图2所示,一种集热保温隔声一体化窗户,包括窗框1,在一个窗框1上集成了内窗2和外窗3,所述内窗2和外窗3均能全部开启或部分开启,即内窗和外窗一定具有可开启部分,所述内窗2采用传热系数小且隔声性能好的玻璃结构,所述外窗3采用太阳总透射比大的玻璃结构。在本实施例中,所述内窗2则为传热系数较小且隔声效果较好的中空双层玻璃结构,所述外窗3为太阳总透射比较大的单层玻璃结构。
如图3、4和5所示,所述内窗2由内开活动窗扇4组成,所述内开活动窗扇4的边缘部分别通过窗扇连接件5与窗框1转动连接,通过内开活动窗扇4能将内窗2全部开启;所述外窗3由固定窗扇6和外开活动窗扇7组成,所述外开活动窗扇7通过窗扇连接件5与窗框1转动连接,通过外开活动窗扇7能将外窗3部分开启,所述外开活动窗扇7采用上悬活动开启结构。
在本实施例中,所述外窗3中的固定窗扇6边缘部通过室外固定压线8和外侧窗室内压线9夹紧固定,所述固定窗扇6两侧的室外固定压线8和外侧窗室内压线9分别与窗框1和中梃10固定连接,所述外窗3中的外开活动窗扇7上下侧边缘部通过外平开窗扇13与窗扇压线11夹紧固定;所述内窗2中的内开活动窗扇4两侧边缘通过内外侧的窗扇压线11夹紧固定,所述窗扇压线11与内平开窗扇12连接。
如图6所示,本发明的集热保温隔声一体化窗户的控制方法,具体为:对于应用于太阳能热利用的情况,当白天太阳升起,辐照量较大,太阳辐射得热大于外窗对流换热失热时,即IT(S,γf)·g>h·(tn-tw),开启内窗,通过外窗向室内辐射得热;当下午太阳落下或阴天工况,辐照量较小,太阳辐射得热小于外窗对流换热失热时,即IT(S,γf)·g<h·(tn-tw),关闭内窗,通过增加对流换热热阻,对室内进行保温。
式中:IT(S,γf)为窗户表面总太阳辐照,W/m2;g为太阳总透射比,h为外窗表面对流换热系数,W/(m2·K);tn为室内干球温度,K;tw室外干球温度,K。
对于应用于隔声的场合,当室外噪声对室内的影响超过室内噪声要求时,关闭内窗,隔绝噪音;当室外噪声对室内的影响未超过室内噪声要求时,可打开或者继续关闭内窗,进行通风或保温隔热。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
