Summary: The study investigates the impact of phase change temperature of phase change material (PCM) on the output power and generated electricity of PCM-TEG system. Results show that optimizing the phase change temperature of PCM can enhance the total generated electricity by as much as 15.6% through matching PCM with thermoelectric properties of the thermoelement. Furthermore, a relationship between the optimal phase change temperature of PCM and the temperature for maximum figure of merit (ZT) of the thermoelement is established, providing a selection criterion for PCM in TEG modules.

Summary: This paper provides a comprehensive review of the classification and performance requirements of phase change materials (PCMs) and the methods of synthetic and characterization of composite PCMs (CPCMs). The thermoregulation effect of CPCMs and its influence on the performance of asphalt pavements are discussed. Results show that organic solid-liquid PCMs and organic-organic eutectic PCMs meet the requirements of asphalt pavements and have a wide range of applications. However, the direct incorporation of PCMs can significantly affect the performance and thermoregulation properties of the asphalt pavement, and various methods must be used to prepare CPCMs to avoid liquid leakage. Experimental characterization and numerical simulation can validate the thermoregulation effect of CPCMs on asphalt pavements.
