Problems solved by technology

However, the cooling of radiant refrigeration technology is usually not controlled by humans, and its cooling is all-time and all-season.
In cold weather conditions, the cooling effect of radiative cooling materials will lead to more energy consumption
The heat preservation or refrigeration temperature can be adjusted according to actual needs, so that it can be applied to a variety of heat preservation and refrigeration environments. This kind of radiation refrigeration material is difficult to detect and is not convenient for subsequent preparation and regulation

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a system and method for testing and analyzing the optical properties of temperature-controlling film materials. Background technique [0002] In the context of the increasingly severe global warming situation, in order to ensure the smooth progress of daily production and life, it is urgent to find an efficient cooling technology. However, traditional cooling methods have various drawbacks. In terms of technical means, traditional cooling methods include air conditioners, refrigerators, etc., but a large amount of electricity will be consumed during the use process. In the current energy structure still using thermal power, this will lead to further aggravation of global warming. In terms of materials, commonly used cooling materials such as reflective coatings, metal-based reflective films, etc., are difficult to produce, complex in production process, and usually expensive. ...
