Abstract With advances in design and manufacturing, the cooling performance of daytime radiative cooling materials has progressively improved. However, there has not been an effective method for comparing the cooling performance of the materials tested in different geographical locations and laboratories. Here, we present a simulation-based method, consisting of the basic radiation theory, the standard solar spectrum, and six standard model atmospheres, for comparing the cooling performance of different daytime radiative cooling materials. The proposed simulation-based comparison method was then used to compare four representative daytime radiative cooling materials selected from the literature. The results demonstrated the effectiveness of the proposed method in comparing the cooling performance of different radiative cooling materials tested under different environmental conditions. With the proposed comparison method, the engineers can choose the most suitable daytime radiative cooling material for a specific environment.

比较不同日间辐射冷却材料冷却性能的模拟研究

摘要 随着设计和制造的进步，日间辐射散热材料的散热性能逐步提高。然而，目前还没有一种有效的方法来比较在不同地理位置和实验室测试的材料的冷却性能。在这里，我们提出了一种基于模拟的方法，由基本辐射理论、标准太阳光谱和六个标准模型大气组成，用于比较不同白天辐射冷却材料的冷却性能。然后使用建议的基于模拟的比较方法来比较从文献中选择的四种代表性白天辐射冷却材料。结果证明了所提出的方法在比较不同环境条件下测试的不同辐射冷却材料的冷却性能方面的有效性。通过所提出的比较方法，工程师可以为特定环境选择最合适的日间辐射冷却材料。
