摘要

Phase change material (PCM) applied in the multi-layer glazed roof can cut down energy consumption and increase thermal comfort by improving its thermal storage capacity. In present work, a numerical model was developed to provide a tool to simulate the heat and light transfer process in a multi-layer glazed roof filled with phase change material for developing engineering analyses. The effects of refractive index and extinction coefficients of PCM in solid state on heat and light transfer of the glazed roof were investigated, which is on the basis of model validation. The convection process of air layer was considered and the temperature difference of interior surface and the upper surface of air layer was calculated. The results show that the refractive index and extinction coefficients of PCM in solid state have both effects on the heat and light transfer process of the glazed roof. The solid extinction coefficients have the opposite effect with the refractive index on the interior temperature. Due to the convection process of air layer, the effects of the two PCM optical parameters in solid state on the temperature difference and total transmitted energy are different.
