新型相变储能材料的研究

相变储能材料技术是近年来材料领域新兴的研究热点，该技术对建筑节能、解决能源紧张有着重要的应用价值．笔者主要介绍了相变储能材料的相变机理及分类，以及利用低共熔点原理制备一种新型的“相变合金”．并采用活性炭及废弃硅藻土对制备的相变材料进行吸附．通过实验研究，制备了一种储热密度大、相变温度较低、适于在建筑结构中的固-固型相变材料．

Study of the New Phase Change Composite Materials

Phase change material technology is one of new topics in the fields of materials science,which is helpful for resolving building energy conservation and energy shortage.This paper introduced the the system of phase-changing material,and made a "phase change alloy" by the low melting point.And the phase change materials which has adsorpted by the activated carbon and abandoned diatomite are the solid-solid phase change materials.These composite phase change materials has a big thermal storage density,a low phase transition temperature,and the composite phase change materials are suitable for the building structure.
