Experimental Investigation of PCM-LWA Composite for Building Wallboard

Abstract:

In this paper, a experimental investigation of application of room wallboard containing Phase-Change-Material / Lightweight-Aggregate composite (PCM-LWA) was carried out. A PCM-LWA composite thermal energy storage material was prepared by absorbing the paraffin. In such a composite, the paraffin serves as a latent heat storage material and the porous lightweight aggregate acts as the supporting material. Mixture of cement paste and epoxy were used to seal the PCM-LWA surface. Through comparing temperature curves of a general room model and the model using wallboards containing PCM-LWA, it can be known that the highest temperature of the room model using the wallboards containing PCM can be controlled in a narrow range. Therefore, room model assembled with the walls containing phase change material can effectively reduce the highest indoor temperature and the range of reduced temperature is about 2~4°C.
