“…Latent heat storage has a high energy density, resulting in a small material mass and smaller storage capacity (Fleischer, 2015). As stated in a journal article by Mishra, Shukla & Sharma (2015), the desired properties for PCMs are:  The melting point should be in the desired temperature range. For example, if we want to incorporate PCM in building materials, then the melting point of the PCM should be around the required room temperature  High latent heat of fusion per unit volume to store more energy in a given volume  High thermal conductivity to aid in the charging and discharging of energy  Low changes in volume during phase change and low vapour pressure to avoid containment problems  Non-flammable and non-toxic  Chemically stable  Low cost and low containment cost Microencapsulated techniques provide opportunities to create advanced PCMs with an area of greater heat transfer.…”

This major research project focuses on reducing the energy consumption, by modelling a radiant floor heating system with phase change materials, in the Toronto climate. Computer generated simulations were performed using DesignBuilder software, using an example of a typical condominium in Toronto .Two south facing suites and two north facing suites were investigated. Of those suites, one north facing suite had PCM below the finished floor, as well as one south facing suite. The objective of these simulations was to determine the impact of using PCM in the condo suites. Three different types of PCM were used, in order to determine which type had the biggest energy savings. The PCMs were M91/Q21, M51/Q21 and M27/Q21. The final results showed that the suites with the M27/Q21 PCM had the lowest energy usage. A cost savings comparison was performed based on the rate of energy used and the cost of the energy, provided by the Ontario Energy Board.

“…Solid-liquid PCMs are commonly utilised as efficient storage materials currently since they are capable of absorbing, storing or releasing large amounts of heat energy, almost isothermally by undergoing phase change, while having relatively high heat capacity and storage, and they experience relatively smaller volume changes during the phase transition process when compared with the liquid-gas PCMs [1], and they have higher latent heat storage capacities than the solid-solid PCMs. The PCM to be used for an application in various fields, such as construction, refrigerators, air-conditioning, textiles, food preparation, astronautics and waste heat recovery, is determined based on the temperature at which phase change occurs, better known as its operating temperature [36]. Vast number of solid-liquid PCMs have been prepared in the past to deduce a solution that provides a highly effective storage system at low costs.…”

Buildings contribute to 40% of total global energy consumption, which is responsible to 38% of greenhouse gas emissions. It is critical to enhance the energy efficiency of buildings to mitigate global warming. In the last decade, advances in thermal energy storage (TES) techniques using phase change material (PCM) have gained much attention among researchers, mainly to reduce energy consumption and to promote the use of renewable energy sources such as solar energy. PCM technology is one of the most promising technologies available for the development of high performance and energy-efficient buildings and, therefore, considered as one of the most effective and on-going fields of research. The main limitation of PCM is its leakage problem which limits its potential use in building construction and other applications such as TES and textiles, which can be overcome by employing nano-/micro-encapsulation technologies. This paper comprehensively overviews the nano-/micro-encapsulation technologies, which are mainly classified into three categories including physical, physiochemical and chemical methods, and the properties of microcapsules prepared. Among all encapsulation technologies available, the chemical method is commonly used since it offers the best technological approach in terms of encapsulation efficiency and better structural integrity of core material. There is a need to develop a method for the synthesis of nano-encapsulated PCMs to achieve enhanced structural stability and better fracture resistance and, thus, longer service life. The accumulated database of properties/performance of PCMs and synthesised nano-/micro-capsules from various techniques presented in the paper should serve as the most useful information for the production of nano-/micro-capsules with desirable characteristics for building construction application and further innovation of PCM technology.

“…Latent heat is the heat released or absorbed by a body or a thermodynamic system during a constant-temperature process. 7 Latent heat storage of PCMs has high energy density when compared to their sensible heat storage. The melting temperature of the PCMs and the latent heat storage are the important criteria when getting chosen for certain applications.…”

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 for the 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.
