Abstract: The study set out to find out the effects of experimental work and get a better understanding of the increased thermal conductivity of PCM, in this case, Paraffin Wax (PW). Experimentally concluded that using Alumina and Copper nanoparticles produced the most excellent thermal conductivity and that Alumina and Copper's nanoparticles had the most significant impact on the conductivity of PCM. Furthermore, mass fractions of prepared PW-Alumina and PW-Copper composites via sonication were 5%, 10%, and 15%, respectively. PW and composite PCMs were examined with scanning electron microscopy for their morphology (SEM). Thermophysical property testing methods were employed as the standard testing procedures. Latent heat and specific heat were measured with a differential scanning calorimeter (DSC). Heat pipe apparatus was used to conductively test thermal conductivity (which was discovered using SEM). In this study, improved thermal conductivity and latent heat were observed in composite PCMs. The enhancement ratio was 10% to 80%, at 15% total weight. Three-stage was measured using a thermocouple and piezoelectric pressure transducer, while temperature data was measured using a temperature logger. Once the experiment reached steady-state temperature, it took 35 seconds to move on to the next stage
