Abstract :
The thermal properties of the shape-stabilized phase change material walls with different structure were studied. The phase change
material is composed of paraffin mixture and high-density polyethylene. The walls including concrete and shape-stabilized phase change
material were prepared respectively by different methods. Preparation methods include direct mixing method and lamination interpolation
method. Heat transfer process in the shape-stabilized PCM walls was studied by comparing with traditional wall. The results showed
that the surface temperature and the heat flow through the phase change material walls prepared by different methods are lower than that
of traditional wall and the change is small. Energy-saving effect of the shape-stabilized PCM walls prepared by lamination interpolation
method is better than that of the shape stabilized PCM walls by direct mixing. Results in this paper can provide the basis for the application
of the shape stabilized PCM walls in the buildings.
