摘　　要：低温定形相变材料是应用于建筑物墙体中的理想储能材料,它可增加墙体的蓄热能力,节约建筑能耗。研究了2种以高密度聚乙烯为支撑材料的低温定形相变石蜡在不同石蜡含量下材料的相变潜热、相变温度、均匀性和稳定性,并讨论了石蜡在材料中的最佳含量范围。研究结果证明了石蜡用于相变墙体中的优越性和可行性,为日后实际应用提供依据。The lower temperature shape stabilized phase change material is an ideal material for accumulation of energy used in building wall.It can increase heat storage capacity of the wall and save energy.The study has been made on two low temperature shape stabilized phase change paraffin taking high density polyethylene as supporting material i.e.phase change latent heat phase change temperaturehomogeneity and stability of shape stabilized phase change paraffin with different content of paraffin.The optimum content range of paraffin required in the material was discussed. The result shows prority and feasibility of paraffin in phase change wall which provides the basis for application in the future.
