摘　　要：我国北方大多村镇建筑仍以火墙等形式采暖,这种间歇式自采暖方式存在能源利用率低和舒适性差等缺点。相变材料由于在其发生相变的过程中可吸收或释放热量,若将其应用在自采暖建筑中,则可极大提高能源利用率,同时通过维持恒定的室内温度恒定以保证居住舒适性。文中主要研究单质和复合相变温度在30~70℃之间的有机相变材料的储热性能,通过差示量热扫描试验和体积变化率试验分析,获得了相变温度37~47℃与相变潜热146~152J/g的复合相变材料,可以在严寒地区村镇自采暖建筑作为储热材料使用。Most villages still use fire wall system for heating in the buildings in northern China,and the system has low energy utilization ratio and comfort level.Phase transformation materials employed in the buildings can not only greatly improve the ratio of energy utilization,but also provide a comfortable living environment,which absorbs and releases heat in the process of phase transition.Energy storage capacity of organic materials with the phase transition temperature range from 30℃ to 70℃ is studied,among which the composite materials are selected for the buildings.The latent heat of the materials with phase change temperature of 37℃ to 47℃ is 146J/g to 152J/g,which is measured by differential scanning calorimetry test and the ratio of volume change test.The materials can be used as thermal storage materials for heating in the buildings in the cold regions of China.
