Evaluation of Energy Performance and Thermal Comfort Considering the Heat Storage Capacity and Thermal Conductivity of Biocomposite Phase Change Materials

The application of phase change materials (PCMs) has been verified as an effective strategy for improving energy efficiency and reducing greenhouse gas emissions. Biocomposite PCMs (Bc-PCM) exhibit large latent heat, chemical stability, a wide temperature range. In this study, thermal conductivity improved Bc-PCM (TBc-PCM) was made via vacuum impregnation with graphene nanoplatelets (GNPs). Chemical stability analysis performance analyses the TBc-PCM were carried out well building simulations comfort analyses. Our results show showed higher heat storage capacity enthalpy value compared to TBc-PCM. exhibited 378% increase in Bc-PCM. Building simulation revealed that annual heating cooling consumption decreased thickness PCM layer increased. addition, larger more during period. On other hand, reduction effect greater when high applied because transfer Thermal evaluation it comfortable applied.
