Abstract

To calculate the value and ratio of the solar radiation energy entering the room absorbed by the cold radiant panels, based on the analysis of indoor solar light propagation, a linear equation method is proposed in this paper. The results show that taking the room as an example, the solar radiation energy absorbed by the cold radiant panels and the absorption ratio are the smallest at noon on the summer solstice. The theoretical maximum value of solar radiation energy absorbed by a cold radiant panel is 32 W/m², and the absorption coefficient varies from 0.13 to 0.28. The solar radiation energy absorbed by the cold radiant panels is related to the view factor between each surface and the reflection ratio of each surface to solar radiation. Therefore, when calculating the solar radiation absorbed by the cold radiant panels, a dynamic algorithm and the influence of various factors should be considered.
