Fundamentals of phase change thermal energy storage (latent heat storage) and technologies for improving functionality.
★Focusing on the technology that efficiently stores heat by utilizing phase changes of substances (melting/freezing) and providing a thorough explanation★ Heat demand! Smart community!
**Lecture Summary** Much of the unused energy, such as solar energy and industrial waste heat, is unstable, unevenly distributed, and exists in a diluted form. Therefore, energy storage becomes a crucial technology for effectively utilizing these resources. In this lecture, we will first focus on technologies for storing heat, particularly those that efficiently store heat by utilizing phase changes in materials (melting/freezing), and we will gently explain the fundamental concepts, including the social background. Next, we will introduce application examples and research and development trends in phase change thermal storage. Additionally, we will discuss methods and application examples for effectively utilizing the phenomenon of supercooling, which allows materials to remain in a liquid state below their melting point, as a means to enhance the functionality of phase change thermal storage.
