“…Thus, the systems that will be presented in this study will be those incorporating PCMs only. Organic PCMs are the most widely used for thermal energy storage due to their suitable melting/solidification temperature, high storage density, chemical stability, and storage capacity [17].…”

“…The integration of PCMs into building envelopes improves thermal comfort by reducing peak and fluctuating indoor temperatures due to a storage density 5-10 times higher than that of standard walls [17]. Moreover, thanks to this high thermal inertia, the temperature peak is delayed in time, resulting in a reduction in peak temperature, which allows taking advantage of lower electricity costs.…”

“…This technique involves the direct incorporation of PCMs into building materials. Direct incorporation is considered the simplest and most economical way to incorporate PCMs into building walls [17]. The main disadvantage of this technique is the risk of leakage of the PCM over time and degradation of the mechanical properties of the building material [45].…”

“…Numerical modeling and simulation of PCMs embedded in building envelopes are very useful for building design and optimization. In most numerical studies, commercial software, such as EnergyPlus, TRNSYS, MATLAB, COMSOL, and ANSYS Fluent, are used to solve the energy equations and to perform numerical simulations under varying weather conditions [17]. The main objective of these simulations is to study and optimize the effect of the integration of PCMs in the walls of buildings, their position in the walls, their thermo-physical properties, such as melting temperature, thermal conductivity, and the effect of their thickness.…”

Latent heat thermal energy storage systems incorporate phase change materials (PCMs) as storage materials. The high energy density of PCMs, their ability to store at nearly constant temperature, and the diversity of available materials make latent heat storage systems particularly competitive technologies for reducing energy consumption in buildings. This work reviews recent experimental and numerical studies on the integration of PCMs in building envelopes for passive energy storage. The results of the different studies show that the use of PCMs can reduce the peak temperature and smooth the thermal load. The integration of PCMs can be done on the entire building envelope (walls, roofs, windows). Despite many advances, some aspects remain to be studied, notably the long-term stability of buildings incorporating PCMs, the issues of moisture and mass transfer, and the consideration of the actual use of the building. Based on this review, we have identified possible contributions to improve the efficiency of passive systems incorporating PCMs. Thus, fatty acids and their eutectic mixtures, combined with natural insulators, such as vegetable fibers, were chosen to make shape-stabilized PCMs composites. These composites can be integrated in buildings as a passive thermal energy storage material.

In the current work, the thermal energy storage cement mortars were prepared by physical mixing between cement mortar and form-stable hydrated salt based on disodium hydrogen phosphate dodecahydrate/carbon nanofiber-expanded graphite (DSP/CNF-EG). The DSP/CNF-EG was incorporated into cement mortar through replacing standard sand of 5 wt%, 10 wt%, and 15 wt%. The pore structure results obtained from the mercury intrusion porosimeter (MIP) demonstrated that the incorporation of DSP/CNF-EG form-stable hydrated salt PCM can cause the increased porosity of the cement mortar. The mechanical strengths of the thermal energy storage cement mortars were decreased with increasing DSP/CNF-EG incorporation amount, and they still meet the strengths of the building envelope. Moreover, dynamic mechanical analysis (DMA) results suggested that the damping properties of the thermal energy storage cement mortar were enhanced by incorporating DSP/CNF-EG, which were related to the porosity and the internal friction action. In addition, the thermal conductivity and the specific heat capacity results confirmed that the introduction of DSP/CNF-EG can endow cement mortar with excellent thermal energy storage capacity. The thermal performance test further indicated that the thermal energy storage cement mortar showed good endothermic and exothermic characteristics, and it played a prominent role in weakening the indoor temperature peak.

Phase Change Materials (PCMs) are utilized to regulate temperature and store thermal energy in various industries such as infrastructure, electronics, solar power, and more. However, they face several limitations, such as leakage, poor thermal properties, incompatibility, as well as high flammability. Polyethylene (PE) is one of many polymers explored to enhance the desirable properties of PCMs, due to their versatile properties such as high strength, durability, chemical resistance, and low cost. The combination of PCMs and PE can be used to create composite materials, through micro/nano-encapsulation, melt-blending, formation of composites and with proper additives. They create enhanced thermal energy storage properties and in the meantime, benefited from the mechanical properties of the PE. This review provides a concise summary of the recent developments regarding PE-enhanced PCMs and provides insights into possible topics for further investigation. We summarised enhancement methods based on commonly adopted types of PEs, such as encapsulation, melt-blending, hot pressing, extrusion, and 3D printing. We then elaborate on how these PE-PCM composites are effectively utilised for heat management applications and the potential future directions in energy-saving buildings, electronic devices, and energy storage systems.
