| 中文摘要: |
| 将相变材料与建筑材料相结合,可以有效提高建筑的蓄热能力,降低室温波幅,实现建筑节能。主要介绍了相变材料的分类、与建筑材料的复合方式,并分析了国内外通过实验探究和数值模拟对被动式和主动式相变储能这两种节能方式的研究现状。针对不同地区的气候环境,需要选择不同相变温度区间的相变材料,必要时需要引入人工冷热源辅助完成相变过程。 |
| 英文摘要: |
| The combination of construction materials and phase change materials (PCMs) is an efficient way to improve the building′s thermal inertia, diminish the indoor temperature fluctuations and achieve building energy efficiency. The classification of PCMs and the means of combination between PCMs and building materials are introduced. Experimental and numerical studies on PCMs used in passive and initiative latent heat thermal energy storage (LHTES) systems are analyzed. It is necessary to select the PCMs with correct switch temperature. The phase change processes sometimes have to occur by resorting to mechanical equipment in some special districts. |
