摘要
相变储热技术是利用低品位能源,实现建筑节能的重要途径。相变储能在建筑节能和暖通空调领域中的应用越来越受到重视,已成为国际研究的热点。研究了在储能领域使用较为广泛的相变材料的种类及其特点。分析了国内外相变储能理论与技术的发展现状以及相变材料在建筑围护结构、太阳房供暖系统、电热蓄热系统及蓄冷空调中的应用。展望了相变材料在蓄能技术方面的发展前景。
Energy storage of phase change materials used in the building fields is more and more valuable and has become focus at home and abroad. The performance and types of phase change materials used in the thermal storage were studied. Development status of thermal stor- age theory and technology of phase change materials was introduced, and application of phase change materials in the building envelope, solar heating system, electric heat-storing system and cool-storing air conditioning system were analyzed. The result shows that the technology of thermal storage of phase change materials has good development prospect.
