Thermal and characteristic analysis of shape-stabilization phase change materials by advanced vacuum impregnation method using carbon-based materials

Abstract

Abstract This study was conducted to energy saving in buildings, with TES system. The manufacturing method of Shape-Stabilized Phase Change Materials (SSPCMs) was developed as the advanced vacuum impregnation. The validation was conducted using Activated Carbon (AC), Expanded Graphite (EG) and Exfoliated graphite (xGnP) as supporting materials and n-octadecnae was used as Phase Change Materials (PCMs). Through various experiments, the feasibility when it applied to in building, and thermal performance of this novel manufacturing method have been confirmed. Also, through the energy simulation, only 1\xa0mm thickness of SSPCMs was applied as wall, reduced building energy up to 255.44\xa0kWh.
