摘要
利用ANSYS分别对外保温、内保温、自保温体系的外墙中柱及梁的热桥进行了二维稳态分析,确定不同保温体系下外墙中柱及梁的热桥影响区域,并对热桥影响区域内的热损显著程度进行了定量分析。结果表明,不同保温体系热桥影响区域不同。外保温体系保温效果最好,内保温体系热桥处热损较大,而自保温体系热桥影响区域内热损最大。
The thermal bridge of middle column and beam in external insulation,interior insulation and self insulation is studied with two-dimensional steady-state method by ANSYS.The influencing zone and the significance level about the heat consumption of the influencing zone in different insulation system is researched.The results show that the influencing zone of thermal bridge is of difference.Furthermore,the insulation effect of external insulation is the best,and the heat consumption of thermal bridge in interior insulation and the heat consumption of the influencing zone in self insulation are significant.
