摘要
本文通过举例计算模拟分析,确定窗口和墙角热桥部位对墙体一维传热的影响,重点分析了表面热流和温度差异与热桥距离的关系,根据分析结果给出测点选择的建议,研究结果对现场外墙检测的选择很有帮助。
This paper simulates thermal bridges in the wall which are brought by window and corner. These thermal bridges will influence one-dimension heat transfer in the wall. The paper analyzes the relationship about distance （distance from thermal bridges） and differentia （heat flow and temperature）. In the end, it proposes the methods to choose the measurement spots. The conclusions of the research are helpful for the in-situ measurement.
