摘要
严寒地区农村住宅南向窗户较大,节能型农村住宅的窗户传热系数仍为墙体传热系数的5倍左右。在试验台上对保温窗帘和保温窗板的热工性能进行了测试。结果表明,采用保温窗帘(板)时,窗户的综合传热系数可降低13.5%～38%,从而使门窗传热能耗比例明显降低。
The rural residential buildings in severely cold zones adopt larger windows,and the heat transfer coefficient of window is about four times more than that of wall for energy saving rural residential buildings.Tests the thermal performances of the insulation curtain and shutter.The results show that the overall heat transfer coefficient of the window reduced by 13.5% to 38% by adopting the curtain/shutter and the energy consumption fraction of door and window is markedly lowered.
