Energy being the strongly depended source for development and industrialization, their storage in any form tends to bridge the gap between demand and supply. Renewable energy technology systems now include energy storage as a crucial component. Thermal energy storage is a technique that stores thermal energy by heating or cooling a storage medium. This allows the energy to be used for heating and cooling purposes later on. The present study develops ternary inorganic salt hydrate eutectic phase change material (EPCM) that is intended for cooling buildings. Melting temperature, melting enthalpy and eutectic composition proportion of inorganic salt hydrate of sodium carbonate decahydrate (SCD), sodium phosphate dibasic dodecahydrate (SPDD), and sodium sulphate decahydrate (SSD) are determined using the eutectic melting point theory. Ternary EPCM is synthesised experimentally in accordance with the percentage of salt hydrates. Graphene nanoplatelets are distributed at different weight concentrations of 0.3%, 0.6%, and 0.9% in order to further improve the thermal performance; at higher concentration above 0.9% the graphene nanoplatelets tends to agglomerate. In order to assess the chemical stability and thermal properties of prepared nanoparticle dispersed PCMs, are experimentally assessed. Findings confirm the ternary EPCM's chemical stability and raise its latent heat with graphene nanoplatelets.

The melting enthalpy and melting temperature have a significant impact on the latent heat that results from phase change materials (PCMs) used for thermal energy storage. Among the PCMs that are currently on the market, inorganic salt hydrates have greater thermal conductivity and latent heat than organic PCMs. However, the problem of salt hydrates' degree of supercooling limits their use in energy storage devices. Using sodium carbonate decahydrate (SCD) and sodium phosphate dibasic dodecahydrate (SPDD), a low temperature inorganic-inorganic eutectic salt hydrate PCM with a higher melting enthalpy and intended phase transition temperature is developed in this research study. The eutectic SCD/SPDD salt hydrate PCM eutectic point and the eutectic composition of salt hydrate PCMs to operate at low temperature range is numerically determined using Schrader equation. By numerical methods we obtain the 68 wt% of SCD with 32 wt% of SPDD to exhibit eutectic SCD/SPDD composite with eutectic melting temperature of 26.2 °C and melting enthalpy of 210.6 J/g. The synthesised eutectic PCM are characterised to explore their chemical stability, latent heat, melting point and their shortcoming due to degree of supercooling. A good way to get around the problem of the supercooling degree is to disperse the nucleating agents. In order to assess the type and degree of supercooling, the produced eutectic PCM composition is experimentally evaluated at 1–10% utilising borax, alumina, and sodium sulphate dodecahydrate as nucleating agents. However, for building cooling applications PCM with minimal degree of supercooling, with the ability to release low enthalpy during discharging is an advantage.

Thermal energy storage through Phase Change Material has been used for wide applications in the field of air conditioning (cooling) and refrigeration, especially at the industrial scale for lower temperature applications like refrigeration and air conditioning, cold storage, cold chain, etc. Generally inorganic and eutectic type phase change materials are used because of long term temperature stability, good latent heat, chemical stability, etc. Latent energy storage technologies, which can improve the thermal inertia of the system, reduce indoor temperature fluctuations, improve thermal comfort, and are becoming an effective way to reduce reliance on traditional systems. In this review, paper attempts have been given to improve the refrigeration system performance by thermal storage with nanoparticles. The use of Phase Change Material may maintain the quality of food for a longer duration of time even though power outage exists. This review paper focuses on different phase change materials used for lower temperature applications. Compared with traditional materials, PCMs can store energy through the utilization of sensible latent heat. The PCMs selected forthe system should possess a suitable melting point, high heat storage density, good thermal conductivity, small volume change; these materials mainly include paraffin waxes, fatty acids, salt hydrates, and eutectics, etc. The main objective of this review paper is to study different latent energy storage materials i.e. organic, inorganic, and eutectic phase change materials for lower temperature applications.
