Radiation cooling radiates heat to outer space through the atmospheric window. There is no energy consumption for the effect of refrigeration. Materials are the key to realizing radiation refrigeration. This paper mainly focuses on radiation refrigeration materials, summarizing some types of requisite materials, including the progress of making radiation refrigeration materials and the kinds of products. Furthermore, it also analyses some radiation effects that various radiation refrigeration products will bring, such as radiation refrigeration film and radiation refrigeration coating. Finally, it looks forward to the future development trend of radiation refrigeration materials.
