相变材料在建筑节能及其它领域的研究与应用

Research and Application of Phase Change Materials in Building Energy Efficiency and Other Fields

相变材料可制成具有储能和调温功能的新型建筑材料,具有储能密度大及近似恒温下的吸热放热等优点,能有效维持室内环境的舒适度,并降低建筑采暖制冷所需的能耗和费用,在建筑节能领域具有广阔的应用前景.此外,相变储能材料在废热回收、冷却、控温等多个领域也都有所应用.本文主要论述了相变材料的分类、蓄热机理及相变建筑材料的复合工艺等,重点介绍了相变材料在国内外建筑节能及其它领域的研究与应用.

Phase change materials could be applied to make new types of building materials with heat storage and temperature adjustment function, which has advantages of a great energy storage density, heat absorption and release at a constant temperature, etc. It effectively maintains the environmental comfort, and reduces the energy consumption and operating costs of building heating or cooling systems, which has broad application prospects in the field of building energy efficiency. Also, phase change materials have been applied in other fields such as waste heat recovery, cooling, temperature control and so on. This paper summarizes the classification of phase change material, storage mechanism, phase change materials and building materials composite technology, etc, focusing on describing the research and application of phase change materials in domestic and abroad
