“…A vapour-compression cooling system employing PCM that shifts the peak load of power consumption was examined by Riahi et al (2021) [82]. More particularly, the dynamic behaviour of the cooling system with and without PCM was appraised and was demonstrated in detail on the warmest day of the year in Tehran, Iran.…”

When it comes to guaranteeing appropriate performance for buildings in terms of energy efficiency, the building envelope is a crucial component that must be presented. When a substance goes through a phase transition and either gives out or absorbs an amount of energy to provide useful heat or cooling, it is called a phase-change material, or PCM for short. Transitions often take place between the matter’s solid and liquid states. Buildings use PCMs for a variety of purposes, including thermal comfort, energy conservation, managing the temperature of building materials, reducing cooling/heating loads, efficiency, and thermal load shifting. Improved solutions are applied using new method and approach investigations. Undoubtedly, researching and applying PCM use in building applications can help create buildings that are more energy-efficient and environmentally friendly, while also increasing thermal comfort and consuming less energy. It provides a possible answer to the problems posed by climate change, rising energy demand in the built environment, and energy use optimisation. However, it is true that no particular research has yet been conducted to thoroughly analyse the linked PCM applications in the building industry. Thus, the principal tactics are addressed in this paper to determine current and efficient methods for employing PCMs in buildings to store thermal energy. By gathering around 50 instances from the open literature, this study conducts a thorough assessment of the up-to-date studies between 2016 and 2023 that used PCMs as thermal energy storage in building applications. As a result, this review aims to critically evaluate the PCM integration in buildings for thermal energy storage, identify a number of issues that require more research, and draw some important conclusions from the body of literature. Specifically, the building envelope roof and external wall uses of PCMs are highlighted in this research. Applications, general and desired characteristics, and PCM types and their thermal behaviour are described. In comparison to a traditional heat storage tank that simply contains water, this review indicates that a water storage tank containing 15% PCM improves heat storage by 70%. Also, less than 7 °C of internal air temperature was reduced by the PCMs in the walls, which avoided summer warming. Finally, using PCM for space cooling resulted in substantial energy savings across the various seasons.

“…Compared to electrical, chemical and hydrogen storages, thermal energy storages are relatively cheaper, faster response, and more flexible temperature range for multi-cascade applications, but with lower energy quality. In recent years, the latent thermal energy storage (LTES) technology has received increasing attention in reducing energy demands through thermal buffering (Jankowski and McCluskey, 2014), decreasing peak power through peak shaving (Riahi et al, 2021), stabilizing power supply by addressing power fluctuation and intermittence (Jouhara et al, 2020), highlighting its significance in addressing global warming and energy challenges (Li et al, 2021).…”

“…An improvement in terms of the coefficient of performance by employing a PCM subcooler within freezers was found by Yan et al [22], who achieved an improvement of 3.3-10.5% when compared to a conventional vapor-compression cycle. In order to reduce the electricity consumption peak, Mosleh et al [23] simulated a vapor compression system that integrated a PCM-based heat exchanger to take advantage of the exterior dynamic conditions. With this solution, the authors were able to move the electricity peak, even if there was a slight reduction in terms of the coefficients of performance.…”

This study concerns the numerical simulation and the experimental implementation of a low-scale Phase Change Material-based (PCM-based) condenser, to be included in a PCM-based portable cooling systems. In this category of cooling systems, the PCM can be integrated either in the condenser or in the evaporator. In the present study, the PCM is integrated in the condenser of the vapor compression cycle to absorb the heat power released from the refrigerant fluid (R134a) during condensation, thus eliminating the need to transfer heat to the external environment. The main objective of the present study is to realize and validate a numerical model capable of simulating both the refrigerant fluid and the PCM thermofluid dynamics. For this purpose, a commercial solver was used for the implementation of the developed numerical model, and experimental tests were performed to validate the numerical simulations results. The paper reports the details and test results of both the numerical model and the experimental apparatus. The simulation results indicate a good accordance between the numerical and experimental data.
