Radiative cooling, as a renewable cooling technology, is expected to mitigate growing global warming. However, the barrier when promoting radiative cooling from the laboratory to practice is still a blind spot and needs to be discussed right now. Here, on the basis of review for brief history, we propose a developing thread that the studies on radiative cooling arise from practice and in turn serves practice at the end. This perspective orderly elaborates fundamental limit in theory, realization of spectral-selective materials, practice on criteria for cooling performance, challenges and corresponding possible solutions in practice, and focusing on serving practice. We hope that the criticism for our own opinion could trigger researchers to deeply consider how to make achievement of radiative cooling better serving practice in the future.
辐射制冷作为一种可再生制冷技术，有望缓解日益严重的全球变暖问题。然而，将辐射制冷从实验室推广到实际应用中的障碍仍是一个盲点，亟待探讨。在此，在简要回顾其发展历程的基础上，我们提出一条发展脉络：辐射制冷的研究源于实践，最终又服务于实践。该观点依次阐述了理论上的基本极限、光谱选择性材料的实现、制冷性能标准的实践、实践中的挑战及相应的可能解决方案，并着重强调服务于实践。我们希望对自身观点的批评能够促使研究人员深入思考如何使辐射制冷在未来更好地服务于实际应用。
