Cold thermal storage can be used to manage peak load when the energy demand is exceeding the capacities of the electric companies. Latent heat thermal storage is more effective because it requires less spacing and has higher thermal capacity than other types. Solidification and melting are taking place in CTS and need more investigation for better performance. Phase change materials properties vary and need more investigation to select the most suitable for a certain application. The analytical equations are needed for design of CTS and get the maximum efficiency out of it. Cost effectiveness is also described.

Thermal energy storage through phase change material has been used for wide applications in the field of air conditioning and refrigeration. The specific use of this thermal storage has been for energy storage during low demand and release of this energy during peak loads with potential to provide energy savings due to this. The principle of latent heat storage using phase change materials (PCMs) can be incorporated into a thermal storage system suitable for using deep freezers. The evaporator is covered with another box which has storage capacity or passage through phase change material. The results revealed that the performance is increased from 3.2 to 3.5 by using PCM.

Thermal Energy Storage (TES) has become extremely important in the recent years since it balances the energy demand and improves the efficiency of the solar systems. It is important that the thermal energy storage systems have the necessary characteristics to improve the performance of the storage. Usage of Phase Change Materials (PCM) for energy storage provides a great benefit but, their low thermal conductivity becomes a major drawback. This can be compensated with the use of phase change material in an appropriate design for successful functioning of the system. This review article summarizes the recent designs of thermal energy storage systems containing Phase Change Material that have been adopted for efficient energy storage.

This work presents an energy/exergy analysis to investige performance of thermal storage unit which loaded with a commercial phase change material (Plus ICE H190). The influence of fluid parameters on the energy/exergy effectiveness was examined. The temporal changes of the energy and exergy rate and performace of the storage unit are obtained  in the results. Latent heat principle is considered an efficient method to gain a higher effectiveness of system from an energy and exergy aspects. The fluid mass flow rate during charging and discharging periods were 2.50 kg/min and 1.26 kg/min, respectively. The results showed a significant increase of thermal resistance on the thermal storage unit performance. Fluid and phase change material show significant temperature difference on the rate of energy/exergy quantites and the time of melting or soldification. Ther results indicated that the average rate of energy and exergy were 1.3 kW and 0.54 kW, respectively. Wheras, energy and exergy  average rate during discarging periods were 1.1 kW and 0.31 kW, respectively. Also, the global rate during the experimetal periods were about 84% and 54%, respectively.

Thermal storage plays a major role in a wide variety of industrial, commercial and residential application when there is a mismatch between the supply and demand of energy. Several promising developments are taking place in the field of thermal storage using phase change materials (PCM) in buildings. In the present paper, a detailed study of the thermal performance of a phase change material system for energy conservation in building is analyzed and discussed. An experiment consisting of two identical test houses has been constructed to study the effect of having PCM panel on the roof of the building. One house is constructed without PCM on the room in order to provide a reference case for comparison with the experimental house that includes the phase change material. The PCM is an inorganic eutectic mixture, which has melting temperature in the range of 26 - 28°C. A mathematical model has been developed in which finite volume method is used to predict the thermal behavior of the ceiling system incorporating PCMs. A comparison with the experimental results is also made.
