One of the interesting applications for Phase Change Materials (PCMs) is in buildings by incorporating them in conventional construction. By including PCM into wall construction, the heat transfer through the wall can be seasonably controlled with the absorption and the release of the latent heat. The choice of phase change temperatures is a key parameter in the design of PCM building materials. This temperature has been studied previously by different researchers. The present work aims to study the thermal behavior of microencapsulated phase change materials incorporated in building material under cyclic convection boundary conditions. The effect of some physical parameters on the thermal behavior of wallboard is also discussed.
