Review on Phase Change Material as thermal energy storage for cooling

As the demand of air conditioners and refrigeration has increased during past many years, the cooling systems can be modified for economic advantage over these outdated cooling plants. In the comfort zone to maintain temperature cooling and heating systems are installed. To replicate the effect of thermal mass of the building, we can use of phase change material depending on the application. Phase change material should have high energy density of melting, high latent heat material and low temperature range. Thermal energy storage through phase change material is capable of storing and releasing large amount of energy and this depends upon shift in phase of material. Heat is absorbed or released when material changes from solid to liquid or vice versa during processes such as melting, solidifying/evaporation. A variety of substances like water, ice, inorganic salts or organic salts are used. In change of state, a large amount of energy known as latent heat can be stored or released at constant temperature. Thus a small difference in temperature is used for storing or releasing energy. Therefore the choice of phase change material mainly depends on the area of application. In this paper we are discussing about the various properties, types and applications of lithium, graphene, aluminum foam, polymer and ceramic Based Phase Change Materials. Due to huge variety of Phase change material, the designer will have more option to choose the material depending on the area of application.

Phase Change Materials for Applications in Building Thermal Energy Storage

TechConnect Briefs 2021, 2021

Phase change materials (PCMs) have excellent thermal energy storage (TES) potential to provide thermal comfort in buildings by lowering the cooling and heating energy demands. The primary grid benefit of thermal energy storage is load shifting and shedding by replacing heating, ventilation, and air conditioning system operation during peak times and recharging the storage system during offpeak times. Additional efficiency benefits come from shifting HVAC system operations to periods when the system can operate more efficiently and at a lower cost. This paper discusses the present state-of-the-art PCMs for thermal energy storage systems for buildings applications and some limitations to phase change materials that negatively impact the performance. Results for two available and environmentally friendly PCMs (BioPCM and DuPont Energain) with different melting ranges applied inside the exterior walls and the roof are analyzed and presented.

Limitations of using phase change materials for thermal energy storage

IOP Conference Series: Earth and Environmental Science

The use of a phase change materials (PCMs) is a very promising technology for thermal energy storage where it can absorb and release a large amount of latent heat during the phase transition process. The issues that have restricted the use of latent heat storage include the thermal stability of the storage materials and the limitation of the container size. The study of the influence of thermal cycling on the properties of PCMs, such as melting temperature and latent heat, is important. It is found that the paraffin wax and fatty acids (e.g., lauric acid, myristic acid, palmitic acid, and stearic acid) have good thermal stability and can be used for solar thermal energy storage applications. However, Calcium chloride hexahydrate (CaCl2. 6H2O) is a good PCM in building applications.
