PROSPECTS OF APPLICATION OF RADIATION COOLING SYSTEMS
Abstract
This article reviews the fundamental principles of radiative cooling technology, highlights the latest research results, design methods for materials and structures, and challenges faced in their implementation. Innovative cooling technologies with lower energy consumption and low carbon emissions are urgently needed to reduce energy consumption. The purpose of this article is to familiarize the scientific community, designers and planners with the latest developments and possibilities of using radiative cooling systems (RCS) in the fields of energy-efficient construction, 3rd generation smart fabric materials, electronic device cooling systems, obtaining drinking water from the atmosphere and agriculture. RCS designs use non-ferrous metals, dielectrics, metastructures, multilayer structures, as well as bionic structures. But their practical application still has serious difficulties. Currently, they are only manufactured in laboratory conditions, and their scalability is limited due to the disadvantages of short durability and high cost. The cooling efficiency in outdoor conditions may depend on various environmental factors. Therefore, it is important to pay attention to the durability and stability of materials, such as self-cleaning, water resistance, mechanical properties and UV resistance. The implementation of RCS in large-scale production depends on the structural design, material manufacturing technology, their cost-effectiveness and environmental impact.
