摘　　要：通过控温箱-双面热流计法对围护结构进行热工分析,测量得出的墙体传热系数为1.28W/(m^(2)·K),利用Fluent对墙体的物理模型进行计算,得出的墙体传热系数为1.31W/(m^(2)·K)(理想检测模型)和1.32W/(m^(2)·K)(实际检测模型),数值计算结果与测试结果误差低于3%。验证得出,墙体传热系数的检测值具有可靠性。This paper uses temperature control box-double sided heat flow meter method to perform thermal analysis of building energy and the wall heat transfer coefficient was measured by this method.Fluent was used to calculate the physical models of the wall.The value of calculation can be used to verify the reliability of the test results.
