Experimental Study of Binary Composite Phase Change Material for Building

Phase change energy storage building material has become a widespread attention for the field of building energy conservation because of its excellent storage properties. The phase change material which is able to adjust the indoor temperature, belongs to the low temperature phase change material. There are lots of kinds of it, and then how to find a suitable phase change material has become a key problem. In this paper, the characteristics of the inorganic material, single organic material, and binary organic material were tested, and the phase change temperature and latent heat of composited phase change material were analysed by differential scanning calorimetry(DSC), which could provide a theoretical basis for the search for the appropriate phase change material.
