摘　　要：天空辐射制冷技术是指利用地球大气层在特定红外波段具备低吸收的特性,通过"大气窗口"波段(主要在8~13μm范围内)向外太空发射红外辐射,以实现建筑表面的被动式降温,是一种无需额外能源供给的节能技术,对于实现建筑“碳达峰、碳中和”目标具有重要作用。从夜间辐射制冷发展到日间辐射制冷技术,有望成为未来建筑节能涂料发展的趋势。本文在对天空辐射制冷技术的基本原理、陶瓷真空微珠保温隔热涂层在建筑上被动式的节能做了分析,并重点讨论了该技术当前所面临的挑战。The atmospheric radiation cooling technology utilizes the earth’s atmosphere to emit infrared radiation into outer space through the“atmospheric window”band(premier wavelength within the 8~13μm)with low absorption characteristics in the specific infrared spectrum,thereby achieving passive cooling of building surfaces.Atmospheric radiation cooling has become an energy-conserving technology that does not require additional energy supplementation and plays a crucial role in realizing the goal of“Carbon Peaking and Carbon Neutrality”in construction sector.With advancements in coating technology,from nighttime radiation cooling to daytime applications,it is expected to become the development trend of building energy-saving coatings in the future.This study elucidates the fundamental principles of atmospheric radiation cooling technology and its contribution to passive energy conservation by incorporating atmospheric raw materials such as ceramic hollow glass microspheres(HGM)into insulation coating system on buildings while also addressing challenges faced by this technology.
