“…They are highly desirable as PCM materials because of their high energy densities, appreciable thermal conductivity, low corrosivity, and compatibility with plastics. Mustafa et al [43] conducted experiments to determine the optimal concentration for maximum solar storage using various PCM substances. The experiments involved a water bath placed on a magnetic stirred hot plate, a beaker container, temperature sensors, a stopwatch, and a data logger.…”

“…In terms of stability, wax proved to be the most stable option for up to ten cycles, while calcium nitrate tetrahydrate was stable for up to six cycles. The addition of certain salts to water reduces the melting point of the water by weakening the hydrogen bonds between individual water molecules through the presence of salt ions [43,44].…”

To address the growing problem of pollution and global warming, it is necessary to steer the development of innovative technologies towards systems with minimal carbon dioxide production. Thermal storage plays a crucial role in solar systems as it bridges the gap between resource availability and energy demand, thereby enhancing the economic viability of the system and ensuring energy continuity during periods of usage. Thermal energy storage methods consist of sensible heat storage, which involves storing energy using temperature differences; latent heat storage, which utilizes the latent heat of phase change materials; and thermochemical heat storage, which utilizes reversible chemical reactions through thermochemical materials. The objective of this review paper is to explore significant research contributions that focus on practical applications and scientific aspects of thermal energy storage materials and procedures. For each type of storage, different materials have been examined, taking into consideration the most recent studies, both for medium and long-term storage and, when possible, comparing methodologies for the same purpose. It has been observed that TCHS systems have the potential to reduce the volume of chemical storage tanks by 34 times using chemical reactions. Among the SHS materials, water, molten salts, and graphite exhibit the highest energy density, with graphite also possessing remarkable thermal conductivity. Nanoparticles can enhance the thermophysical properties of TES materials by increasing their thermal conductivity and wettability and improving intermolecular characteristics. The use of biobased PCMs for applications that do not require very high temperatures allows for maximizing the efficiency of such storage systems.

Technological improvements and increasing energy demand necessitate energy efficient designs for heat transfer systems. The storage and reuse of heat energy plays an important role in the development of energy-efficient systems. Phase change materials (PCMs) are crucial components which increase energy efficiency in heat exchangers as can be applied to many systems. In this study, the heat transfer performance of different types of phase change materials in a regenerative heat exchanger was investigated according to different parameters. Reynolds number depending on the hot fluid velocity (Re=400, 800, 1200, 1600), hot fluid inlet temperature (Tsıcak,giriş=40, 60, 70, 80℃), and different types of phase change materials (RT60, RT100, and SP70) are the parameters used in this study. ANSYS Fluent software was used for computational fluid dynamics analysis. As a result, it has been determined that when the Reynolds number of the hot fluid in the heat exchanger was increased in the range of Re=400-1600, the heat transfer effectiveness increase of 17%; when the hot fluid inlet temperature was increased in the range of Thot,inlet=40-80℃, the heat transfer effectiveness increase of 21%. As regards the effect of different types of phase change materials, the heat transfer effectiveness was 81% for RT60, 79% for SP70 and 76% for RT100. It has been evaluated that, with the results obtained from this study, heat exchangers with higher heat transfer effectiveness and higher energy storage capacity can be designed.
