Opportunities in Latent Thermal Energy Storage by Phase Change Material for Lower Temperature Applications: A Review

Abstract

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.
