Phase change materials (PCMs) store and release energy in the phase change processes. In recent years, PCMs have gained increasing attention due to their excellent properties such as high latent heat storage capacity, appropriate solid-liquid phase change temperature, thermal reliability, and low cost. Herein, classification, characteristics, and evaluation criteria of organic/composite PCMs are systematically illustrated, and some typical preparation methods are introduced, such as in-situ polymerization, interfacial polymerization, spray drying method, porous materials adsorption method, sol-gel method, meltimpregnated and mixing method, electrospinning method, vacuum infiltration and ultrasonic method are introduced. In addition, this review presents some applications of PCMs in the utilization of solar energy, building materials, air conditioning, industrial waste heat recovery, and military camouflage and stealth. Finally, the development tendency of PCMs is discussed.

“…Even without external energy supply, the system can provide longer hot water supply time. Guerraiche et al 39 investigated the use of PCM as a heat accumulator through experiments and numerical studies, as shown in Figure 4, the added heat accumulator acts as a thermal compensator, so that the parabolic trough solar concentrator can be used without strong solar radiation or short stable energy output under cloudy conditions. Zayed et al 8 reviewed the application of cascaded PCM, which is used in the field of storage tanks for solar collectors, as shown in Figure 5, they summarized different types of solar collectors, and analyzed the thermal performance of the cascaded latent heat system and the utility.…”

This article reviews the design of solar phase-change energy storage systems and their applications in residential buildings. The solar thermal collection system has high heat collection efficiency, no pollution, and it is also widely used in the field of building heating. In order to improve the efficiency of the solar collector system, the researchers found that integrating phase-change materials (PCMs) into the solar thermal collector system can achieve this goal, but there will be a problem of PCM leakage. Some researchers have solved this problem by microencapsulating PCMs, the thermal conductivity and energy storage efficiency of the PCMs after microencapsulation will be greatly affected. Adjusting the solar collector to an appropriate inclination angle can achieve the highest heat collection efficiency. Choosing the PCM in the appropriate temperature zone can improve the system efficiency. For the separated solar collector system, the parts that need to be considered include the type of heat exchanger, the structure of the energy storage heat exchanger, the shape of the heat exchanger fins, the type of solar collector, and so on. All in all, coupling PCM into the solar collector system can improve energy efficiency reduce carbon emissions and have good economics, the maximum internal rate of return of solar collectors integrated with PCMs in residential and industrial applications is 22% and 17.2%.

“…The result suggests that the storage capacity and utilisation rate of 3-PCM energy storage tanks are relatively high and that the shape of the tank has no effect on the storage capacity at a fixed tank volume. Guerraiche et al [39] implemented an experimental and numerical study of a solar collector using phase change material as heat storage. It was found that the phase change material showed good heat retention of 2 hours to 1 hour 40 minutes for water inlet temperature 30°C and 40°C respectively.…”

Two different charging modes of a thermal energy storage tank system employing multi-phase change material for compression heat storage in an adiabatic compressed air energy storage process was simulated to compare their performance. The modes are mod1 with higher mass flow rate and low temperature and mod2 with higher temperature and low mass flow rate of heat transfer fluid respectively. A mathematical formulation of the energy interactions in the HTF and the PCM filling the TEST was discretized using implicit finite difference technique and solved in Matlab using a matrix inversion technique. The developed model showed good agreement with experimental data of temperature profile of heat transfer fluid during the charging mode. The two modes were compared using metrics such as charging rate, discharging rate, charging efficiency, discharging efficiency, charging and discharging exergy efficiency, and overall exergy and energy efficiency. It was found that mod2 performs better than mod1 in both the charging and discharging cycle. The round trip efficiency of mod1 ranges from 0.87 to 0.77 with a mean value of 0.76 whereas that for mod2 ranged from 0.97 to 0.79 with an average of 0.78. Moreover, the overall exergy efficiency ranges from a peak value of 0.48 and 0.55 to the least value of 0.33 and 0.44 in mod1 and mod2 respectively, corresponding to average efficiencies of 0.45 and 0.51 in mod1 and mod2 respectively. The numerical results offer guidance for the selection of the appropriate mode.
