探索被动辐射冷却在可持续发展方面的实际应用

Global energy consumption is significantly impacted by the thermal regulation demands in the industrial and building sectors, creating an urgent need for sustainable thermal energy solutions. Passive radiative cooling (PRC) has emerged as a promising strategy, capitalizing on the natural thermal exchange between Earth and outer space to achieve cooling without electricity input. Recent advancements in PRC materials and systems have prompted researchers to explore wider applicability and enhanced functionality. PRC study now extends beyond cooling-optimized spectral designs focused on high solar reflectance and thermal emittance. The current primary research gap centers on leveraging PRC technology to address thermal management needs beyond mere cooling while incorporating specific functionalities for various practical applications. In this perspective, we analyze the current challenges in PRC implementation and identify potential research opportunities for future exploration. Additionally, this perspective seeks to stimulate innovative approaches to PRC design that address real-world applications, bridging the gap toward diverse practical thermal management solutions.
