摘　　要：为分析夹芯无机保温外墙板热工性能,文中建立了夹芯无机保温外墙板仿真模型,分析不同墙厚及窗墙比对夹杂无机保温外墙平均传热系数的影响。结果表明,各构件位置的最低温度均高于露点温度,证实上述位置具有良好的保温性能;模拟能量随墙体厚度增加的降低速率为0.585 W/mm,模拟传热系数随墙体厚度增加的降低速率为0.001 [W/(m^(2)·K)]/mm;计算传系数与模拟传热系数值两者的误差在5%以内,证实所建模型的准确性。所有窗墙比下,凸窗的传热系数高于普通窗的传热系数,但是其传热系数的增加速率低于普通窗的传热系数增加速率。In order to analyze the thermal performance of sandwich inorganic insulation exterior wall panel,a simulation model of sandwich in-organic insulation exterior wall panel was established in this paper,and the effects of different wall thickness and window ratio on the average heat transfer coefficient of inorganic insulation exterior wall were analyzed.The results show that the lowest temperature of each component is higher than the dew point temperature,which proves that the above positions have good thermal insulation performance.The decrease rate of simulated energy with the increase of wall thickness is 0.585 W/mm,and the decrease rate of simulated heat transfer coefficient with the in-crease of wall thickness is 0.001[W/(m^(2).K)]/mm.The error between the calculated transfer coefficient and the simulated heat transfer co-efficient is less than 5%,which confirms the accuracy of the model.The heat transfer coefficient of the bay window is higher than that of the common window,but the increase rate of the heat transfer coefficient is lower than that of the common window.
