摘要
摘 要:通过数值模型分析了地下工程表面设置玻化微珠砂浆的防结露作用,建立了空气波动温度下壁面温度响应模型,基于有限差分法进行模型的求解,计算结果表明,玻化微珠抹面层的设置能够降低壁面温度热延迟,提高热响应速度和壁面温度,减少壁面与空气之间的温度差,从而减少表面结露的产生。
Abstract: The wall temperature corresponding model was built, the model based on the finite difference method was analyzed. The results showed that the application of hollow bead glazed mortar layer can reduce the wall temperature delaying, increase the thermal response speed and wall temperature in order to prevent the condensation on the surface.
