摘要
本文通过模拟金属屋面板材的服役环境及热平衡分析,提出了一种热反射金属屋面板材隔热性能测试方法。该测试方法不仅能正确地反映金属冷屋面板的隔热性能,而且还弥补了利用太阳反射比与半球发射率两个参数表征其隔热性能存在的不足。
Through analyzing the heat balance of roof and simulating the service environment of heat reflecting metal roof plate, the paper relates the test method for the heat insulation performance of heat reflecting metal roof plate. The method not only right reflect the heat insulation performance of heat reflecting metal roof plate but also make up for deficiency of characterizing heat insulation effect of heat refleting metal roof plate using the solar reflectance and the hemispherical emittance.
