Abstract:

Carbon neutrality should be achieved as soon as possible with regard to curbing global climate change. It is our common pursuit to accelerate the green and low-carbon transformation of the whole society. In this regard, the refrigeration technology faces major change on its development path. As a completely passive cooling technology, radiative sky cooling does not consume any energy or produce any environmental pollutant, which is extremely prospective. On the basis of introducing the fundamental theory of radiative cooling technology, the typical technologies and cooling effects of radiative cooling materials in recent years have been summarized. Then, we elaborate the current research status of radiative cooling materials in different fields. Finally, we analyze the application scenarios of the technology in the carbon neutralization, as well as its development trends and problems that radiative cooling materials have encountered. The development and application of radiative cooling materials make great contributions to energy conservation and emission reduction for China.

Key words: carbon neutrality, green and low-carbon transformation, Cosmic Microwave Background radiation energy, radiative sky cooling, passive refrigeration technology, radiative cooling material, energy saving and emission reduction
