Thermal Energy Storage Technology of Composite Phase Change Materials: Composite Phase Change Materials Preparation and Application in Heating System of Cold Region

Phase change thermal storage technology can overcome problems such as time intermittency, space dispersion, and intensity instability in the process of thermal energy conversion and utilization. It has a wide range of application prospects in the fields of renewable energy, industrial waste heat recovery, and building energy conservation. Composite phase change materials can improve the thermophysical properties of traditional phase change materials, leading to better results in practical engineering applications. This book introduces the preparation method of composite phase change materials and the test method for thermal and physical properties. It further discusses the variation of thermal properties of materials under different conditions. The book includes experimental analysis and theoretical modeling of a packed bed heat storage device with spherical encapsulated thermal storage material. Additionally, it presents the design of a low carbon heating system for use in cold climate areas and discusses the multi-objective optimization method for the thermal performance of a phase change heat storage device. The methods for material preparation, testing, and heat storage device design introduced in the book provide valuable references for the application of medium and low-temperature thermal storage engineering.
