| 内容記述 | Phase change materials (PCM) provide an innovative approach to enhancing radiant floor heating systems (RFHS), with encased PCM systems offering improved energy efficiency and design flexibility. Integrating PCM within tubes and hot water pipes addresses key challenges, including thermal efficiency, response speed, temperature control, costs, and energy usage. This study focuses on optimizing the thermal performance of encased PCM systems for practical applications. It reviews PCM applications, thermal properties, encapsulation techniques, system design, operation strategies, and performance evaluation, supported by mathematical modeling, CFD simulations, and experimental validation. Key analyses include the advantages of encased PCM systems, adjustments to hot water pipe positioning, optimizing PCM encasement shapes, and introducing double-layer PCM structures to enhance heat storage and release efficiency. The paper concludes with insights into technical and economic challenges and outlines future directions for sustainable RFHS development. | |||||||
