| Popis: | ACTI; International audience; In this article, we study the influence of the insertion of a phase change materials (PCMs) in the ceiling of a community hall on its comfort during the summer period. This study was realized using a dynamic thermal simulation of the building using a modelica library (BuildSysPro). Initially, we have defined materials used for the building including the characteristics of the phase change material used (thermal conductivity, melting temperature, specific heat capacity, latent heat and density). We have tested two configurations: insertion of a layer of PCM mortar and incorporation of PCM in rock wool ceiling tiles. We study the influence of the over-ventilation during night on these two cases. By comparing the simulation results during summer, we have noticed that the over-ventilation during night has a significant influence in reducing the inner temperature of the building. The insertion of PCM in a layer of ceiling tiles didn’t have a significant efficiency contrary to the insertion of a layer of PCM mortar. Secondly, we have optimized the PCM characteristics in order to achieve more comfort during summer. |
