    Co-Authors: Muhammad Amin, Erwin Prawiro, Rizky Achmad Luanto, Nandy Putra, Teuku Meurah Indra Mahlia, Engkos Achmad Kosasih
    Abstract:

    Abstract Increased energy consumption in buildings is a worldwide issue. This research is concerned with the implementation of a phase change material for thermal storage. This concept has gained great attention as a solution to reduce energy consumption in buildings. Beeswax, which is a phase change material with a high thermal capacity, is investigated in this research. This paper is intended to measure and analyze the thermal properties of Beeswax/graphene as a phase change material. The melting temperature, thermal capacity and latent heat were determined using differential scanning calorimetry (DSC), and the thermal conductivity was investigated using a thermal conductivity measurement apparatus. To discover the change in the physical properties due to the effect of nanoparticles, the viscosity of the material was investigated as well. Based on the result from the DSC, the latent heat of 0.3 wt% Beeswax/graphene increased by 22.5%. The thermal conductivity of 0.3 wt% Beeswax/graphene was 2.8 W/m K. The existence of graphene nanoplatelets enhanced both the latent heat and thermal conductivity of the Beeswax. Therefore, based on this result, Beeswax/graphene is concluded to have the potential to reduce energy consumption in buildings.

  • thermal properties of Beeswax cuo nano phase change material used for thermal energy storage
    International Journal of Technology, 2016
    Co-Authors: Nandy Putra, Erwin Prawiro, Muhammad Amin
    Abstract:

    Experimentation on and implementation of phase-change materials for thermal storage is attracting increasing attention by those seeking a potential resolution to energy issues. This study investigates Beeswax as a high thermal-capacity phase-change material with the objective of analyzing the thermal properties and behaviors of Beeswax/CuO nano-PCM. The study uses differential scanning calorimetry apparatus to measure the melting temperature and thermal capacity of nano-PCMs. The study found nano-PCM melting temperatures of 63.62°C, 63.59°C, 63.66°C, 63.19°C, and 62.45°C at 0.05, 0.1, 0.15, 0.2, and 0.25 wt%, respectively. FTIR testing found no chemical reaction between CuO and Beeswax. The existence of CuO nanoparticles enhanced thermal conductivity of Beeswax but reduced its heat capacity. However, the change in latent heat caused no significant effects in the performance of Beeswax/CuO. Thus, the results showed that heat transfer of composite Beeswax/CuO melts faster than base phase-change material.

  • Experimental performance analysis of Beeswax/expanded graphite composite for thermal energy storage in a shell and tube unit
    International Journal of Green Energy, 2018
    Co-Authors: Abhay Dinker, Madhu Agarwal, Ghanshyam Das Agarwal
    Abstract:

    In this study, pure Beeswax and its novel composite with expanded graphite (10% wt.) were tested for thermal storage efficiency in a rectangular shell and helical tube storage unit. Low thermal conductivity of Beeswax is improved by adding expanded graphite of 10% wt. Thermal characterization of Beeswax and its composite was performed using differential scanning calorimetry and thermogravimetric analysis. Effect of hot fluid flow rates (0.25 liter per minute [LPM], 0.5 LPM, and 1.0 LPM) and inlet temperatures (60oC, 70oC, and 80oC) on the charging time of Beeswax and its composite was studied and compared. Charging time of Beeswax and its composite reduced with an increase in fluid flow rate and inlet temperature. At 0.5 LPM flow rate and 80°C inlet fluid temperature, the charging time of composite was reduced by 630 min as compared to pure Beeswax. Smaller charging time, improved thermal conductivity, and better thermal storage efficiency of composite material suggest it as a useful storage material for a wider range of applications.

  • Experimental Study on Thermal Performance of Beeswax as Thermal Storage Material
    Materials Today: Proceedings, 2017
    Co-Authors: Abhay Dinker, Madhu Agarwal, Ghanshyam Das Agarwal
    Abstract:

    Abstract Thermal energy storage is one of the key areas of energy conservation. Identification and applications of thermal storage materials are the primary concerns for fabrication of an efficient thermal energy storage system. In this study, Beeswax was introduced as a natural phase change material for low-temperature thermal energy storage. Surface characterization of Beeswax was done using Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Fourier Transform Infra-red Spectroscopy (FTIR). Thermal properties of Beeswax were determined by Differential Scanning Calorimetry (DSC). A shell and tube type thermal storage unit was fabricated to study the thermal performance of Beeswax as the thermal storage material. Storage material formed the shell part while hot fluid was allowed to pass through the centrally placed copper tube. Temperature variation with time was studied at nine points of thermal storage units. Effect of various flow rates and inlet temperature of heat transfer fluid (HTF) on the heating profile of Beeswax was studied. Objective of this study is to analyse potential of Beeswax as thermal storage material and its application for low-temperature thermal storage.

  • preparation characterization and performance study of Beeswax expanded graphite composite as thermal storage material

    Co-Authors: Abhay Dinker, Madhu Agarwal, Ghanshyam Das Agarwal
    Abstract:

    In this study, Beeswax as a new energy storage material and its composite with expanded graphite were prepared and characterized for their surface and thermal properties. Surface characterization showed no chemical interaction between Beeswax and expanded graphite. The thermal conductivity of the composite was improved with 117% enhancement. The thermal performance of Beeswax and its composite as a heat storage material was studied in a rectangular shell-and-tube thermal storage unit. The melting point of the composite remained almost same as that of Beeswax; however, the melting time was reduced considerably, from 540 to 360 min with inlet water at 80°C and a 2-lpm flow rate.
