摘　　要：辐射制冷是一种被动制冷技术,不消耗能量,将物体的能量以辐射的方式透过大气窗口(8~13μm)传递到宇宙深处。将辐射制冷技术应用到建筑供冷中,可以降低建筑能源消耗,减少二氧化碳排放,缓解温室效应。目前辐射制冷技术面临的主要难题是制冷功率低和辐射制冷功率对大气透明程度的依赖性大,解决这些问题的主要途径包括研制高性能辐射制冷材料、选择合适的制冷系统以及与其他相关技术,如太阳能集热、太阳能光伏发电进行集成。从辐射制冷技术的基本原理、辐射制冷材料的研究现状和辐射制冷系统的基本形式以及辐射制冷技术面临的挑战对辐射制冷技术的发展现状进行了综合论述,从而使相关研究者快速地对辐射制冷技术有较为全面的了解。Radiative cooling is a passive cooling technology which independent of energy consume.It transfer the energy of the object to the universe by the way of radiation through atmospheric window(8~13μm).The application of radiative cooling technology to building cooling supply can reduce the energy consume and emission of CO2,so to remission greenhouse effect.At present,the challenges of radiative cooling are small cooling power and dependent of transparency of atmospheric window.The main solution methods include developing perfect radiative cooling materials,selecting suitable cooling system and integrated with other correlative technology such as solar heat collection technology and solar photovoltaic technology.This text reviewed radiative cooling technology from its basic theory,development of materials,the basic system form and the challenge of radiative cooling,which can let related researcher know the technology of radiative cooling as fast as possible.
