“…It is found that the change in arrangement in the inner tubes for pure phase change material led to solidification and melting rates increased by 23% and 41%, respectively. In this study, Ladekar et al 49 investigated latent heat TES performance in a tank with a heat pipe for maximum performance and a storage tank with copper pipes. HTF considered was Water and PCM considered was Paraffin wax inside the heat pipe and copper pipe separately for analysis.…”

This article reports detailed investigation of using different Phase Change Materials (PCM) in various designs of Thermal Energy Storage (TES) Devices: specifically, heat exchanger. The focus is on the performance analysis of different types of heat exchangers acting as TES having various PCMs which are substantially reviewed in this paper. The study highlights the difference in their geometry and performance output. Further, the importance of different performance enhancement methods with parametric study of different heat exchangers using PCM is described. From the detailed investigation, finally, it is realised that the different factors such as no. of outer tubes, no. of inner tubes, tube material selected, type of PCM, provision of an extended surface, use of different metal foams and nanoparticles, various types of composites, charging and discharging characteristics and packed and cascaded units are different heat transfer enhancement methods to improve the heat transfer. A novel kind of heat exchanger known as Webbed tube heat exchanger using PCM is discussed for an efficient TES unit. Further, a review of quantitative analysis of melting time, solidification time, charging and discharging time is discussed.

“…Although fins can considerably reduce the phase change time of PCM, heat pipes can give even better results. Ladekar et al [140] found that the melting and solidification time of PCM decreased by 45% and 40%, respectively when the copper fins were replaced by heat pipes. Among the reviewed papers, the greatest reduction of melting time, by 94%, after the addition of heat pipe to the non-enhanced enclosure was achieved by Motahar and Khodabandeh [141], whereas Yang et al [30] reported the smallest melting time reduction, by 11.26%.…”

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.

“…In order to enhance the efficiency of latent heat thermal energy storage (LHTES) with embedded heat pipes, Ladekar et al [ 22 ] experimentally investigated the charging and discharging process in the case of using a heat pipe and a copper pipe. The results show that the capability to store heat for the charging process phase increases when majoring the volume flow rate, and early heat extraction when discharging becomes achievable.…”

This study presents an experimental and numerical investigation into the efficiency of a two-stage heat recovery–storage system for reducing the thermal energy losses in the industry. The system is designed to recover and store waste thermal energy from residual fluids using heat pipes for recovery and an environmentally friendly phase change material for heat storage. Experimental investigation was conducted using water as the primary agent and varying the temperature between 60 °C, 65 °C, and 70 °C at a constant flow rate of 24 L/min. The secondary agent, also water, was used at an initial temperature of 10 °C and the flow rate was varied between 1 L/min, 2 L/min, and 3 L/min. The results show that the system had a peak efficiency of 78.1% and was able to recover a significant amount of thermal energy. This study demonstrates the potential of this system to reduce the thermal energy losses in the industry and highlight the importance of further research and development in this field, as the industry is responsible for approximately 14% of the total thermal energy losses and finding efficient ways to recover and store waste thermal energy is crucial to achieving sustainable energy consumption.
