The potential of using Phase Change Material (PCM) in wooden house has been investigated. Since the cost of the PCM is high, searching for a laying position with high heat absorption and dissipation efficiency has been shown as a problem to solve. At the same time, the internal screen also causes changes in the room surface temperature, which in turn affects the heat absorption effect of PCM. In this study, we focused on how the internal screen affects the thermal storage effect of PCM and discuss the means to improve the thermal storage effect.
