个人辐射制冷织物的研究进展

Personal Radiative Cooling Textile Generation

在高温环境中对人体降温以保持舒适性是很重要的。近年来,辐射制冷织物通过红外光学性能的设计,能够在不消耗能量的情况下将人体的热量尽可能散出去,为实现在室内和室外场景中的人体降温提供了新的机会。与室内可控热环境不同,室外热环境的特点是太阳辐照强度强,因此,在将人体热量尽可能散出去的同时还需阻止太阳热量的输入。基于室内和室外热环境的差异,分别从室内和室外应用场景的角度介绍了辐射制冷织物的设计策略,并综述了其发展情况,最后对辐射制冷织物的未来发展方向进行了展望。

In a hot environment,personal cooling is important to maintain thermal comfort.In recent years,radiative cooling textiles can enhance the heat dissipation of the human body through the design of the infrared optical properties without consuming energy,which provides a new opportunity for realizing personal cooling in indoor and outdoor environments.Unlike the indoor controllable thermal environment,the outdoor thermal environment is characterized by strong solar irradiance intensity.Therefore,it is necessary to prevent the input of solar heat while enhancing human body heat dissipation.Based on the difference between indoor and outdoor thermal environments,we introduce the design strategy of radiative cooling textiles from the perspective of indoor and outdoor application scenarios,summarize the recent progress of radiative cooling textiles,and prospect the future development.
