Global cooling demands are increasing rapidly as a result of the increasing trends of heatwaves and the increase of living standards. Meeting essential cooling demands by the impoverished is extremely challenging due to their lack of access to electricity. Herein, we report a passive design with dissolution cooling in combination with solar regeneration for the conversion and storage of solar energy for cooling without electricity consumption. As a proof of concept, cooling was achieved by dissolving a NH₄NO₃ salt in water and a three dimensional solar regenerator was applied to regenerate the NH₄NO₃ salt. The cooling power of such a system could reach up to 191 W m⁻². Importantly, the passive cooling design separates the dissolution cooling and solute regeneration physically and time-wise, allowing for energy storage and utilization even across seasons. This work shines light on the utilization of solar energy for cooling, especially for off-grid communities.

用于冷却的太阳能转换和存储

由于热浪的增加趋势和生活水平的提高，全球制冷需求正在迅速增加。由于缺乏电力供应，满足贫困人口的基本制冷需求极具挑战性。在此，我们报告了一种被动设计，将溶解冷却与太阳能再生相结合，用于转换和存储太阳能以进行冷却而无需消耗电力。作为概念证明，通过将 NH ₄ NO ₃盐溶解在水中来实现冷却，并应用三维太阳能再生器来再生 NH ₄ NO ₃盐。这种系统的冷却功率可达 191 W m ^-2. 重要的是，被动冷却设计在物理上和时间上将溶解冷却和溶质再生分开，即使跨季节也能储存和利用能量。这项工作揭示了利用太阳能进行冷却，尤其是对离网社区而言。
