摘要
随着空调能耗的逐年上升,相变材料因具有节能和削峰填谷的优势成为学者研究的热点,5~12℃的相变材料成为常规空调蓄冷的最佳选择。阐述了相变材料的特性及分类,对无机相变材料、有机相变材料、有机—无机相变材料的优缺点及国内外对提高相变材料导热率、降低过冷度、抑制相分离的研究现状进行了总结,从而展望了空调领域相变材料的发展趋势。
With the increase of air-conditioning energy consumption,phase change materials have been a research hot spot because of their advantages on energy saving and peak load shifting,5~12℃phase change materials are the optimal choice for conventional air-conditioning systems with cold storage.The characteristic and classification of phase change materials are described.The advantages and disadvantages of inorganic phase change materials,organic phase change materials,and organicinorganic phase change materials,as well as the overseas and domestic research status in improving their thermal conductivity,reducing the supercooling,inhibiting the phase separation are summarized.The development trend of phase change materials applied in air-conditioning field is briefly prospected.
