【摘要】 相变储能材料技术是近年来热能领域和新材料领域新兴的研究热点,该技术对于解决能源供需失配、提高能效以及太阳能利用等具有显著的应用价值。本文主要介绍多孔介质基相变储能复合材料的研究结果及其在建筑节能中的应用研究。多孔介质基相变储能复合材料是以纳米多孔石墨或无机非金属多孔介质为储藏介质,以有机相变材料为储能功能材料,采用真空浸渗等方法制备的复合材料。本文报道多孔介质基相变储能复合材料的相变行为、循环耐久性和导热性能研究结果,以及基于相变储能材料技术的空调蓄冷/蓄热技术的研究结果。最后借助建筑模型实验对相变储能材料技术在建筑节能中的应用效果进行了初步分析。更多还原

【Abstract】 Phase-changing material technology is one of new topics in the fields of thermal energy andmaterial science,which is helpful for resolving the mismatch between energy supply and demand,improving the energy efficiency and utilization of solar energy.In this paper the recent research results ofphase-changing material based on porous materials and application technology of phase-changing materialin energy conversation in buildings are presented.The phase-changing material was fabricated byincorporating organic phase-changing materials into nano porous graphite or inorganic porous materials bymeans of vacuum impregnation.The phase-changing behavior,cycling behavior,thermal conductivity ofthe phase-changing material and the thermal energy storage technology based on the phase-changingmaterial are presented in the paper.Finally,the application potential of phase-changing material in energyconversation in buildings is analyzed based on a building model.更多还原
