The market for radiation refrigeration materials has huge development potential. Ruiling New Energy is at the forefront of the domestic industry.

Radiation refrigeration materials are special functional materials constructed from organic polymers and functional inorganic materials that have both high reflectivity and selective high emissivity in the atmospheric window infrared band (8-13 μm wavelength). They are a type of metamaterial. The working mechanism of radiant refrigeration materials is to reflect most of the solar heat so that it does not absorb solar energy. At the same time, by emitting infrared rays of a specific band, the heat of surface objects is transmitted to low-temperature outer space in the form of infrared electromagnetic wave radiation, thereby achieving the purpose of radiative refrigeration.

Outer space and the sun are the earth’s most important cold and heat sources, and play a role in maintaining the earth’s energy balance. In recent years, with the continuous development of scientific research, passive radiative refrigeration technology based on low-temperature cold sources in outer space has attracted widespread attention from domestic and foreign research institutions once it was discovered.

Compared with traditional active, high-energy-consuming refrigeration technologies such as air conditioners and refrigerators, radiant refrigeration technology has the remarkable characteristics of zero energy consumption and zero pollution, which is of great significance in promoting the realization of dual-carbon goals. In the future, radiant refrigeration technology will be generated based on radiant refrigeration technology. The material is expected to play an important role in building cooling, agricultural greenhouse cooling, electronic equipment cooling, outdoor equipment heat dissipation and other fields, and the market development prospects are broad.

According to the “2023-2028 Radiant Refrigeration Materials Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center, Research on radiant refrigeration materials first started in the 1960s. Early research was limited to the research and development of nighttime radiant coolers. However, in recent years, as institutions and enterprises in various countries continue to increase technology research and development, radiant refrigeration technology has been continuously upgraded, and related innovations have Advanced results in radiation refrigeration materials continue to emerge.

For example, in 2020, the Photothermal Control Center of Nanjing University in China developed a new material polymer nanofiber (es-PEO) film using the principle of radiation refrigeration; in 2022, scholars from Purdue University in the United States and scholars from the University of Cambridge in the United Kingdom collaborated to develop a structural color film, achieving Efficient daytime radiation cooling; in 2023, the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, developed a dielectric/polymer composite film material with a 3D porous structure, which achieved excellent radiation cooling effects. In the future, as relevant research and development processes at home and abroad continue to accelerate, the radiation refrigeration materials industry is expected to usher in a golden period of rapid development.
