摘要

摘要辐射冷却的原理是将地球多余的热能辐射到外太空，近年来取得了很大进展。辐射冷却受到空气质量的显著影响，目前报道的冷却器只能在晴朗的天空下工作。此外，世界上大多数工业城市都面临着严重的雾霾问题；因此需要解决改善雾度条件下的冷却性能的问题。我们提出了一种水蒸发辅助辐射冷却技术，实验结果表明，在白天的雾霾中，有6.4°C的显著亚环境冷却。

Using passive evaporation to improve radiative cooling performance

Abstract. The principle of radiative cooling is to radiate the extra heat energy of Earth into outer space, and a lot of progress has been made in recent years. Radiative cooling is significantly affected by the air quality, and coolers reported at present only work well under a clear sky. Moreover, most of the world’s industrial cities are facing serious haze problems; thus improving the cooling performance under haze conditions needs to be addressed. We propose a water evaporation assisted radiative cooling technique, and the experimental results showed a remarkable subambient cooling of 6.4°C in daytime haze.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
