摘　　要：对4种可以用于辐射制冷的化合物进行了辐射制冷效果的对比试验,并测定了其吸收比和法向发射比。结果表明,4种化合物都具有很高的辐射率,且与其辐射制冷实验结果表现出一致。首次提出CaF2用于辐射制冷,实现了制冷空间温度比环境温度低8-11℃的结果。The radiation cooling efficiency and the absorption/emissivity ot tour eompounas were testefl. The data show that they exhibit high radiation,which are in line with their radiation cooling efficiency. CaF2 was firstly reported to use for radiation cooling, and it made the temperature difference between the cooling space and the surrounding reach to 8-11℃.
