| 摘 要： | 利用DeST-c软件,通过大量的模拟分析,探讨了不同气候区门窗玻璃的热工性能参数即传热系数(U)和太阳得热系数(SHGC)对建筑能耗的影响.结果表明:从节能方面考虑,对于严寒地区(哈尔滨),应降低K值,增加SHGC值.对于夏热冬暖地区(广州),应降低SHGC值.对于夏热冬冷地区(上海)和温和地区(重庆),应降低K值和SHGC值.而对于寒冷地区(北京),当窗墙比较大时,应降低K值和SHGC值;当窗墙比较小时,应降低K值,增加SHGC值.门窗玻璃的SHGC值全年固定不变对建筑节能不利.理想的门窗玻璃SHGC值应能随季节变化进行相应调整.

| Abstract: | The effect of the thermal properties(heat transfer coefficient U and solar heat gain coefficient SHGC) on building energy con-sumption of glass window and door in different climate zones was simulated by DeST-c software.The study shows that in order to save energy,the U-value of glass window and door should be reduced and the SHGC value should be increased in chilly zone(Harbin).The SHGC value should be reduced in hot summer and warm winter zone(Guangzhou).In hot summer and cold winter zone(Shanghai) and wa... |
