ABSTRACT Phase change material (PCM)‐based heat storage systems utilize the absorption or release of latent during a phase to store thermal energy. Nevertheless, effectiveness these is restricted by shape and structure their confinement, as well conductivity material. This work investigates novel method enhance PCM concurrently utilizing two techniques: inclusion nanoparticles alteration system's geometry. Introducing enhances medium while altering shape, which improves transfer efficiency adjusting surface area available for exchange. RT‐35 was tested use in energy space heating cooling. With melting point 35°C, chosen moderate building temperatures storing releasing The results indicate that using can greatly systems. By incorporating Al 2 O 3 nanoparticles, time reduced 20% compared pure PCM, it more efficient than best case modification. These findings including modifying are effective methods improve performance devices. technology's potential surpasses this study's limits be utilized diverse applications, solar storage, district cooling, industrial process heat.
