“…The same reduction of the solidification time, i.e., by 50%, might be achieved by decreasing the HTF inlet temperature by 10 • C [23]. Regarding the HTF flow rate, Salyan et al [28] reported that when the HTF volumetric flow rate increased six times, the melting and solidification time of PCM decreased by 24.6% and 39.3%, respectively. The same melting time reduction, by 24%, was achieved by Karami and Kamkari [29], but in their investigations, the volumetric flow rate of HTF increased only two times.…”

An application of latent heat thermal energy storage systems with phase change materials seems to be unavoidable in the present world. The latent heat thermal energy storage systems allow for storing excessive heat during low demand and then releasing it during peak demand. However, a phase change material is only one of the components of a latent heat thermal energy storage system. The second part of the latent heat thermal energy storage is a heat exchanger that allows heat transfer between a heat transfer fluid and a phase change material. Thus, the main aim of this review paper is to present and systematize knowledge about the heat exchangers used in the latent heat thermal energy storage systems. Furthermore, the operating parameters influencing the phase change time of phase change materials in the heat exchangers, and the possibilities of accelerating the phase change are discussed. Based on the literature reviewed, it is found that the phase change time of phase change materials in the heat exchangers can be reduced by changing the geometrical parameters of heat exchangers or by using fins, metal foams, heat pipes, and multiple phase change materials. To decrease the phase change material’s phase change time in the tubular heat exchangers it is recommended to increase the number of tubes keeping the phase change material’s mass constant. In the case of tanks filled with spherical phase change material’s capsules, the capsules’ diameter should be reduced to shorten the phase change time. However, it is found that some changes in the constructions of heat exchangers reduce the melting time of the phase change materials, but they increase the solidification time.

“…Phase change material (PCM) has been commonly used in heat exchangers [1,2], solar energy storage systems [3][4][5][6][7], and electronic component thermal management systems [8][9][10][11] due to its stable phase change temperature and high energy storage density. With the development of electronic devices to miniaturization and high power, higher requirements are put forward for their heat dissipation performance [12,13].…”

In this paper, heat transfer characteristics of phase change material in rectangular containers are numerically analyzed. The inclination angles of the container refer to 0?, 90?, and 180?. Both theoretical and practical periodic temperature boundary conditions are taken into consideration, in which the periodic temperature boundary conditions include 50-80?C and 65-80?C. The comparison study is carried out through the liquid fraction and temperature histories during the heat transfer process under these different boundary conditions. It is indicated that there are large differences between the calculated results under the theoretical and the practical periodic temperature boundary conditions when the temperature boundary is 50-80?C, while the theoretical and the practical periodic temperature boundary conditions of 65-80?C have relatively little effect on the numerical results of the heat transfer process of the phase change material. Furthermore, compared with the temperature increasing stage, the numerical results calculated under the theoretical and the practical boundary conditions have more significant differences in the temperature decreasing stage. The research conclusion of this paper can provide a theoretical basis for the application of PCM under periodic temperature boundary conditions.

“…Energy from wastes combustion can be stored by using a thermal energy storage sub-system, so it can be used whenever be needed [10]. Thermal energy can be stored in the form of sensible heat or latent heat [11,12]. Some of the technologies applicable are using heat recovery device with heat storage medium such as water, phase change materials, or solid.…”

The main problem related to thermal energy is that the thermal energy must be used directly and immediately as generated. For example, the thermal energy of solid waste combustion can be directly utilized for power generation. However, studied of thermal energy storage technology is still placed on the second opinion on waste to heat energy. The heat can be stored using a simple or mobilized system which can store thermal energy and can be brought to somewhere it is needed, for example on domestic heating or drying usage. This article studied and evaluated a micro thermal energy storage system from household waste combustion into a warm water that is great for washing clothes, dishes, shower, and other purposes of household needs. System considered was a simple manner and water is used as the heat energy storage medium. In this study, the equations for initial parameter calculation were presented theoretically based on thermodynamic principle. This paper is hopefully beneficial to the researchers and engineers for preliminary design and development of a heat storage systems technology.
