Manufacturing Phase Change Material with (50%, 60%) Paraffin Wax-Magnetite (50%, 40%Fe3O4) in Concrete Encapsulation as Thermal Energy Storage

Introduction

The increasing demand for renewable energy and the need to reduce energy consumption have led to the development of innovative technologies for thermal energy storage. One such technology is the use of phase change materials (PCMs) that can absorb and release heat energy as needed. In this study, we investigated the manufacturing of PCMs using a combination of paraffin wax (PW) and magnetite (Fe3O4) in concrete encapsulation as thermal energy storage.

Background

PCMs are materials that can absorb and release heat energy as they change phase from solid to liquid or vice versa. They have been widely used in various applications, including building insulation, refrigeration, and energy storage. However, traditional PCMs have limitations, such as low thermal conductivity, low latent heat capacity, and high cost. To overcome these limitations, researchers have been exploring new materials and composite PCMs.

Methodology

In this study, we prepared two types of PCMs with different compositions: PW50% FE3O450% and PW60% Fe3O440%. The mixing process was carried out at 80 °C for 10 minutes with the help of sonication to create an efficient material as thermal energy storage. The resulting PCMs were then characterized using various techniques, including X-Ray Diffraction (XRD), Vibrating Sample Magnetometer (VSM), Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Energy Dispersive X-Ray (EDX) analysis.

Results

The results of the characterization and testing of the PCMs are presented below:

  • Thermal Energy Absorption: The PW50% FE3O450% sample had a heat energy absorption value of 0.09 J, while the PW60% Fe3O440% sample had a value of 0.07 J.
  • Latent Heat Enthalpy: The PW50% FE3O450% sample had a latent heat enthalpy of 17.13 J/g, while the PW60% Fe3O440% sample had a value of 15.56 J/g.
  • Peak Melting Temperature: The PW50% FE3O450% sample had a peak melting temperature of 56.81 °C, while the PW60% Fe3O440% sample had a value of 54.23 °C.
  • Thermal Conductivity: The PW50% FE3O450% sample had a thermal conductivity of 0.54 W/MK, while the PW60% Fe3O440% sample had a value of 0.48 W/MK.
  • Critical Temperature and Time: The PW50% FE3O450% sample had a critical temperature of 61.31 °C and a critical time of 25496 seconds, while the PW60% Fe3O440% sample had a critical temperature of 59.15 °C and a critical time of 23456 seconds.
  • Latent Heat Value: The PW50% FE3O450% sample had a latent heat value of 7210 J/G, while the PW60% Fe3O440% sample had a value of 6800 J/G.

Discussion

The results of this study demonstrate that the PCMs prepared using a combination of PW and Fe3O4 have promising thermal energy storage properties. The PW50% FE3O450% sample had a higher thermal energy absorption value, latent heat enthalpy, and peak melting temperature compared to the PW60% Fe3O440% sample. The PW50% FE3O450% sample also had a higher thermal conductivity and critical temperature compared to the PW60% Fe3O440% sample.

Conclusion

In conclusion, this study demonstrates the potential of PCMs made from a combination of PW and Fe3O4 as thermal energy storage materials. The results of this study suggest that the PW50% FE3O450% sample has the most promising thermal energy storage properties. The application of PCMs in building systems can optimize energy use and reduce the burden on the cooling system or heater, which ultimately contributes to the sustainability of the environment.

Future Work

Future work should focus on optimizing the composition and preparation method of the PCMs to improve their thermal energy storage properties. Additionally, the application of PCMs in building systems should be further investigated to determine their potential for energy savings and environmental sustainability.
