摘 要：基于Ansys Workbench热力学模块对蒸压加气混凝土外墙传热模式进行了分析，并对研究单元进行建模，确定了模型边界条件及荷载加载形式。通过对3 mm、20 mm等不同厚度砌筑灰缝进行建模研究，探讨了不同灰缝厚度情况下，蒸压加气混凝土砌块墙体温度的分布情况。结果表明，薄灰缝砌筑可以显著减少蒸压加气混凝土砌块墙体的“微热桥效应”，从而降低墙体热量流失。灰缝散失的热量占墙体总散失热量百分比y与灰缝厚度x的关系为：y=0.946x+3.247。
Abstract: Based on the thermodynamics module of Ansys Workbench, the heat transfer mode of the outer wall of autoclaved aerated concrete was analyzed, and the research unit was modeled to determine the boundary conditions of the model and the form of load loading. Through the modeling study of masonry mortar joints with different thickness such as 3 mm and 20 mm, the temperature distribution of autoclaved aerated concrete block walls with different thickness of mortar joints was discussed. The results show that the thin mortar joint masonry mortar plays a positive role in reducing the "micro-thermal bridge effect" of autoclaved aerated concrete block wall and reducing the heat loss of wall. The relationship between the ratio of heat loss from ash joints to total heat loss from wall(y) and the thickness of mortar joints (x) is y=0.946x+3.247.
