基于红外热像法的建筑围护结构传热系数与太阳光光照强度的关系研究

Relationship Between the Heat Transfer Coefficient of Building Envelope and Solar Light Intensity Based on Infrared Thermography

通过室内试验测量不同太阳光光强下的物体表面温度,依据试验数据分析建筑围护结构传热系数与太阳光光照强度之间的关系,最终得到建筑围护结构传热系数随光照强度变化的关系式。所提出的改进方法使得应用红外热像法测量建筑围护结构传热系数的实用范围更广。

The surface temperature of objects under different solar light intensity is measured by indoor experiments. Based on the experimental data, the relationship between the heat transfer coefficient and the light intensity of the building envelope is analyzed, obtaining theinner relationship between them. The improved method proposed in this paper makes the application of infrared thermography to measure the heat transfer coefficient of the building envelope more widely.
