Abstract: According to the technology of thermal storage and the characteristics of energy-saving wall,a new vision of Sandwich composite wall was proposed.By this vision,phase change materials worked as heat-driven source,setting of materials, construction, building as a whole.And based on the heat transfer theory,the process of laminated phase change materials which release heat in winter,storage thermal in summer was analysed. The result shows that the complex system have double effect on self-thermostat and energy-saving.
