Development and thermal characterization of an innovative gypsum-based composite incorporating phase change material as building energy storage system

摘要

This study aims at developing a new integrated component in a passive solar wall to achieve high thermal energy storage potential in building materials. This component was manufactured by conditioning the paraffin inside 24 copper tubes, which were regularly inserted and aligned in a gypsum matrix. Firstly, an investigation by means of a differential scanning calorimeter (DSC) was carried out to obtain the latent heat and the transition temperature of the selected phase change material (paraffin). Secondly, an additional study was conducted to gauge the improvement of energy storage performance in classical construction material (gypsum) when incorporating paraffin by the method of transient guarded hot plates.
