通过基于 VO2 的可切换核壳颗粒的可扩展自适应辐射冷却膜
Scalable self-adaptive radiative cooling film through VO2-based switchable core–shell particles
中文简介
高效被动冷却技术的发展引起了广泛关注。然而，由于温度变化，辐射冷却材料的冷却功率与实际冷却需求之间存在不匹配。因此，需要能够适应不同天气条件的辐射冷却材料。在这项研究中，提出了一种可扩展的自适应辐射冷却膜。通过将VO基核壳纳米粒子掺入PE基体中，实现了具有自适应能力的辐射冷却膜。通过米氏理论和蒙特卡罗（MC）方法预测了薄膜的辐射特性。考虑了两种壳材料：BaF 和 ZnS。评价了壳材料、粒径、内外径比、掺杂浓度和薄膜厚度对薄膜辐射性能的影响。对薄膜进行了优化设计。计算冷却功率的变化来评估自适应性能。薄膜的冷却功率最大变化为 61.7 W/ (BaF) 和 60.7 W/ (ZnS)。采用TRNSYS对薄膜的节能性能进行了模拟。这项研究为具有高自适应冷却性能和耐用性的可扩展辐射冷却膜提供了一种有前途的解决方案。

there is a necessity for radiative cooling materials that can adjust to diverse weather conditions. In this study, a scalable self-adaptive radiative cooling film was proposed. By incorporating VO-based core-shell nanoparticles into PE matrix, the radiative cooling film with self-adaptive ability has been achieved. The radiative properties of the film were predicted through the Mie theory and the Monte
