Abstract

This article summarizes the types of phase change materials and analyzes the typical applications of phase change materials in building envelopes. The phase change latent heat energy storage system possesses the characteristics of stable working temperature, simple process flow and high heat accumulation density. This kind of materials can be integrated with buildings in a variety of ways, using their own heat release/heat absorption characteristics to release and store thermal energy, thereby increasing the utilization rate of renewable energy. Studies have shown that the phase change heat storage unit can effectively improve the thermal comfort of the indoor environment, reduce indoor temperature fluctuations and the waste of building energy. On the basis of previous research on phase change materials in walls, roofs, floors and windows of building envelopes, the paper analyzes the existing research findings on energy-saving heat accumulation buildings. Finally, the future research directions of phase change materials are prospected.
