摘要
针对贵州不同气候区域特点,利用FLUENT软件模拟研究常见的自保温外墙热桥结构,得到热桥部位的温度场分布和内表面最低温度,分析贵州不同气候区域热桥是否结露,并对比研究了几种建筑热桥的处理方式。研究结果表明:在贵州地区降低室内环境湿度或对热桥部位进行外保温处理都能有效地解决热桥结露的问题。
According to the different climate zones of Guizhou province, a common thermal bridge of self-insulation external wall was analyzed by FLUENT. Temperature field of the thermal bridge and inner surface minimum temperature were obtained. Condensation problem of thermal bridge in different climate zones of Guizhou province was analyzed, and several processing methods of thermal bridge were studied. The results show that reducing indoor humidity and exterior insulation technologies can solve thermal condensation effectively.
