Abstract

This chapter explores the potential of glass-encapsulated phase change materials containing nanoparticles (Nano-PCM) for photothermal transmission and building energy efficiency. The study examines the effects of different nanoparticles and their composites on light absorption, thermal conductivity, and photothermal conversion through material preparation, experimental testing, and modeling analysis. Paraffin-based composites doped with CuO, ZnO, and Al2O3 were prepared and optimized for dispersion. Results showed CuO improves short-wave absorption and heat transfer, while Al2O3 enhances phase change heat storage. Experiments and models demonstrated that Nano-PCM doped with composite nanoparticles (CuO:Al2O3 = 4:6) improves photothermal performance, seasonal thermal regulation, and indoor comfort. Simulation analyses highlighted the role of nanoparticle migration in heat transfer. Comprehensive evaluations revealed significant energy savings, reducing cooling needs in summer and enhancing winter heating. This study offers theoretical and practical insights for Nano-PCM applications in building energy conservation and future optimizations.
