摘　　要：通过室内模型试验分析环境风速对建筑围护结构的传热系数的影响。首先设计、制作用于红外检测的试验箱,使用红外热像仪测量箱体表面在不同风速下的温度变化,依据试验数据分析建筑围护结构传热系数与风速之间的关系,得到建筑围护结构传热系数随风速变化的关系式。所提出的改进方法,使得应用红外热像方法测量建筑围护结构的传热系数既有效、又便捷。The influence of wind on the heat transfer coefficient of building envelope is analyzed by indoor model test.First,a model is designed and manufactured for infrared detection.And then,the infrared thermography is applied to measure the model’s surface temperature under different wind speeds.According to the experimental data,the relationship between heat transfer coefficient and wind speed is analyzed.The method proposedis very effective and convenient.
