“…The use of metal foam and nanoparticles to enhance the TC of PCMs has a good effect. Senobar et al 23 132 found that the high-porosity foamed copper PCM has a high latent heat and a small increase in TC. Adding a small amount of nanoparticles to it can maintain high latent heat and take advantage of natural convection.…”

The use of cold storage devices to store energy at low peaks of power usage and release it at peaks is an economic measure. It is also one of the main means to solve the imbalance between electricity shortages during the day and abundance at night. Adding cold storage balls equipped with phase change materials (PCMs) into water cold storage devices can utilize the sensible heat of water and the latent heat of PCMs for cold storage, which has a high energy storage density and can provide cold water with a suitable temperature. PCMs can be divided into organic phase change materials (OPCMs) and inorganic phase change materials (IPCMs), but both have defects. Adding additives or other materials to them to form composite phase change materials (CPCMs) can obtain suitable thermal properties. In the process of material application, some PCMs have problems of poor thermal conductivity (TC) and liquid leakage. The use of additives such as expanded graphite (EG), metal foam, and nanoparticles is a better solution to the above problems. In recent years, many scholars have researched PCMs and additives for increasing thermal conductivity (AITC). However, there is still a lack of detailed comparison among EG, metal foam, and nanoparticles. This article will introduce the PCMs used in the temperature zone (TZ) of cold storage air-conditioning systems (CSASs) and analyze their advantages, disadvantages, and improvement methods. This paper will focus on the latest research on the effect of additives such as nanoparticles, EG, and metal foam on the TC of PCMs. It will also compare the special effects of AITC in preventing supercooling, preventing phase separation, preventing leakage of liquid PCMs, and flame retarding. The future research directions of AITC will be discussed.

Considerable literature has studied different techniques to improve the thermal performance of latent heat thermal energy systems (LHTES) that utilize phase change materials (PCMs). This study aims to contribute to this growing area of research by using honeycomb structure and exploring the effect of heat transfer fluid (HTF) configuration and honeycomb cell angle on the thermal performance of the LHTES during melting and solidification processes. In this work, five cases were designed: case (a) was regarded as reference case; cases (b) and (c) were related to HTF configuration; cases (d) and (e) were used to study the effect of honeycomb cell angle. A numerical study was conducted using ANSYS FLUENT R19.3, followed by experimental validation. In this study, a good agreement is obtained from the validation process. Computational fluid dynamics (CFD) model results show symmetrical melting and solidification behavior when using a honeycomb structure. The results of the HTF configuration show a significant effect. For case (c) with a multiple water block, significant melting and solidification enhancements are obtained with 56% and 50%, respectively. Thus, the HTF configuration can improve the thermal performance of the storage. However, considering different honeycomb cell angles show an insignificant effect on the melting and solidification rates.

The form‐stabilized phase change materials (PCMs) comprised of lauric acid (LA), high‐density polyethylene (HDPE) and graphene nanoplates‐carbon nanofibers (GNP‐CNF) hybrid fillers were synthesized by melt blending method in this work, and the effects of GNP‐CNF mass ratio on thermal properties were investigated. The results from FT‐IR and XRD reveal that LA, HDPE, GNP and CNF were integrated with each other in a physical manner. The LA/HDPE/GNP‐CNF composites possess melting points very close to that of pure LA, with melting latent heats of 113.83–119.84 J/g. Thermal conductivity results indicate that the effect of GNP is better than that of CNF at the same content. The synergistic effect of hybrid carbon fillers can achieve higher thermal conductivity value compared to a single GNP or CNF. The synergistic thermal conductivity improvement mechanism is also analyzed. The sample SN2 (GNP: CNF is 1.7:0.3) exhibits the best thermal conductivity of 0.759 W/(m·K), with 2.73 times that of SN0. It also presents satisfactory thermal stability and reliability, allowing it to have promising applications in thermal energy storage.
