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 two-dimensional steady state analysis of the thermal bridge of the external wall and the beam of external insulation, internal thermal insulation and self-thermal insulation system was carried out by ANSYS respectively. The influence zone of the thermal bridge of the external column and the beam under the thermal insulation system was determined, Quantitative analysis of the degree of heat loss significance in the area affected by the bridge. The results show that different thermal insulation systems have different influence zones. The thermal insulation system has the best thermal insulation effect, the thermal loss of the thermal insulation system at the thermal bridge is larger, and the thermal loss in the thermal bridge affected zone is the largest.
