Background
Under the current severe global warming situation, in order to ensure the smooth proceeding of daily production and life, the search for an efficient cooling technology is urgent. However, conventional cooling methods have various disadvantages. In terms of technical means, the traditional cooling means comprises an air conditioner, a refrigerator and the like, but a large amount of power consumption is generated in the using process, and the global warming is further increased under the condition that the current energy structure is still powered by fire power. In the aspect of materials, common cooling materials such as reflective coatings, metal-based reflective films and the like have high production difficulty, complex production process and generally high cost, and although the conventional cooling materials have a relatively obvious cooling effect, the conventional cooling materials are difficult to be really popularized and applied.
As a new cooling technology, the radiation refrigeration technology is widely concerned by researchers due to the high-efficiency and zero-energy-consumption cooling effect. The main mechanism is that the radiation refrigeration material with high visible light emission and high intermediate infrared emission is utilized, and when sunlight is reflected and possible absorption is reduced, self energy is continuously emitted out through an atmospheric window through an intermediate infrared band, so that the temperature reduction below the ambient temperature is realized. However, the cooling of the radiation refrigeration technology cannot be controlled manually, and the cooling is all-time and all-season. In cold weather conditions, the cooling effect of the radiant cooling material can lead to more energy consumption. The radiation refrigeration material can be used for regulating and controlling the heat preservation or refrigeration temperature according to actual requirements, so that the radiation refrigeration material is suitable for various heat preservation and refrigeration environments, is difficult to detect and is inconvenient for subsequent preparation regulation and control.
