Abstract

Under periodic outdoor temperature fluctuation, unsteady two-dimensional numerical simulation for a room with phase change materials in walls is performed to assess the effects of phase change materials on the room temperature fluctuation. The primary affecting factors such as the thermo-physical properties and thickness of PCMs are investigated. The results show that the daily temperature fluctuation is reduced by using PCMs. To resist the outdoor climate in summer, the function of the lateral wall with PCMs is better than that of the ceiling and ground with PCMs. To balance excess cooling power in summer or excess heating power in winter it is better to adopt a ground and ceil with PCMs. The present work is helpful to the application of PCMs in buildings for reducing indoor temperature fluctuation in both summer and winter.
