| Abstract | ||||
| Converting waste to a value-added material is a fortune. At the meantime highlighting the utilization of renewable solar energy as an inconsumable energy cradle is a future prospect to overcome the energy shortage and crisis. In this regard, storing the solar energy for the use at the off-sun periods is essential. Introducing sawdust waste for thermal energy storage system is a ecological chance. Treated sawdust was mixed with the environmentally benign magnetite to be a composite and mixed with technical grade paraffin base PCM. The composite was characterized through X-ray diffractometer (XRD), Transmission electron microscopy, TEM analysis and Scanning Electron Microscope, SEM (augmented with Dispersive X-Ray Analysis, EDX). Micrographs and Fourier transform infrared (FTIR) exhibited that the prepared composite substance is well prepared. The sawdust is subjected to the PCM system in various mass % ranged from 0.5 to 4%. Subsequently, the thermal system outline is presented and compared. The experimental data revealed that the addition of 2.0 weight percentage of the PCM of composite material showed the superior system performance. The system is achieved a heat gained reached to 82 kJ/min in comparison to 7 kJ/min for the 2.0% WCM-PCM and pristine PCM, respectively. Thereby, the current investigation is introducing the waste sawdust as an energy storage enhancement system that could be applied in heating application systems. | ||||
