以内蒙古农村住宅围护结构外表面为研究对象,通过实验研究的方法,定量分析了吸收系数的两个影响因素—颜色和粗糙度对围护结构外表面热物性的影响.结果表明:墨黑色试件的表面温度最高,信号白试件的表面温度最低,二者在白天9:00～17:00平均温度相差15.198 ℃.粗糙度为10.032 μm的表面温度最高,4.504 μm的表面温度最低,二者在白天9:00～17:00平均温度相差2.46 ℃,夜间各粗糙度试件平均温度最大偏差为0.57 ℃.深颜色表面热稳定性较差,浅颜色表面相对较好.粗糙度为13.423 μm的全天表面净得热量波动最小,粗糙度越小,表面热稳定性越差.

In this present work, the external surface of envelope structure for rural housing in Inner Mongolia is studied. Based on the experimental methodology, the influence of two factors, color and roughness, on the thermal properties of exterior surface of building envelope is analyzed. Results show that the surface temperature of the dark black sample is the highest, and that of the signal white sample is the lowest. The difference of the average temperature with the two specimens about different color between 9:00 to 17:00 is 15.198 ℃. The highest surface temperature is the specimen with roughness of 10.032 μm, and the lowest surface temperature is with roughness of 4.504 μm. The difference of average temperature with the two specimens about different roughness is 2.46 ℃ in the daytime from 9:00 to 17:00, and the maximum deviation of the average temperature at night is 0.57 ℃. The thermal stability of the envelope surface with dark color is poor, while the surface with light color is relatively good. The results show that the fluctuation of net heat gain is the smallest when the roughness is 13.423 μm. The smaller the roughness, the worse the thermal stability of the surface is.
