随着能源的消耗增大,提高能源的利用率势在必行。相变材料作为新一代环保节能材料,通过物相变化,可从环境中吸收或释放热量,达到储能调温的需求,对于能源的合理利用具有重要的研究意义。将相变材料应用于建筑材料中,制成节能墙板、地板、门窗、玻璃等,可以有效地利用太阳能和建筑中的废热、余热,具有广阔的应用前景。本文综述了相变储能材料的主要种类及制备方法,分析其在建筑绿色节能建材领域的应用进展,并探讨其发展趋势。
As energy consumption increases, it is imperative to increase energy efficiency. As a new generation of environmentally friendly energy-saving materials, phase change materials can absorb or release heat from the environment through the phase change to meet the needs of energy storage and temperature regulation, which is of great significance to the rational utilization of energy. The phase change material used in building materials, made of energy-saving wall panels, floors, windows, glass, etc., can effectively use solar energy and waste heat in the building, with a broad application prospects. This paper reviews the main types of phase change energy storage materials and preparation methods, analysis of its application in the field of building green energy-saving building materials, and explore its development trend.
