Abstract
Energy consumption of a building is highly dependant on the thermal properties of building materials. In the passive application of structural thermal storage using PCM (Phase Change Material) wallboard, the thermal behavior of PCM helps the surface temperatures of a room envelope to be maintained around the phase change temperature of the PCM. Therefore, by combining a proper PCM with wallboard materials, cooling or heating load of a building can be significantly reduced. This paper is on the thermal simulations of a model room that includes PCM-wallboard on the inner surface of the room. The objective of the study is to prove the enhanced thermal performance of the laminated type PCM-wallboard in a real situation and to investigate the dependency of the enhancement on the thermal characteristics of PCM. Among different conditions and configurations considered in this study, it was found that a PCM (16.7％ in mass) with a narrow phase change zone could increase the minimum room temperature by over 2℃.
