Application of phase change energy storage in buildings: Classification of phase change materials and packaging methods

Phase change energy storage plays an important role in the green, efficient, and sustainable use of energy. Solar energy is stored by phase change materials to realize the time and space displacement of energy. This article reviews the classification of phase change materials and commonly used phase change materials in the direction of energy storage. Commonly used phase change materials in construction and their packaging methods are listed according to the properties of phase change materials. Through different packaging methods to enhance heat exchange, this work solves the problem of material leakage and summarizes the advantages and disadvantages of those methods through comparative analysis. The impact of macro-encapsulation and micro-encapsulation on material encapsulation are also outlined. The simulation and model construction methods of different packaging methods are reviewed. This research is dedicated to the comparative analysis of the selection of phase change materials and packaging methods in buildings a to actively promote the promotion and application of phase change energy storage in buildings.
