“…A series of studies 173,185,225 have been conducted to investigate the effect of adding different concentrations of Al 2 O 3 nanoparticles and changing the size and quantity of fins. In the field of LTESSs of SACSs, this type of hybrid strengthening studies mainly uses the method of adding nanoparticles to PCM and changing the geometric parameters of fins in the container.…”

Solar air conditioning is an important approach to satisfy the high demand for cooling given the global energy situation. The application of phase-change materials (PCMs) in a thermal storage system is a way to address temporary power problems of solar air-conditioning systems. This paper reviews the selection, strengthening, and application of PCMs and containers in latent thermal storage system for solar air-conditioning systems. The optimization of PCM container geometry is summarized and analyzed. The hybrid enhancement methods for PCMs and containers and the cost assessment of latent thermal storage system are discussed. The more effective heat transfer enhancement using PCMs was found to mainly involve micro-nano additives. Combinations of fins and nanoadditives, nanoparticles, and metal foam are the main hybrid strengthening method. However, the thermal storage effect of hybrid strengthening is not necessarily better than single strengthening. At the same time, the latent thermal storage unit has less application in the field of solar airconditioning systems, especially regarding heat recovery, because of its cost and thermal storage time. The integration of latent thermal storage units and solar air-conditioning components, economic analysis of improvement technology, and quantitative studies on hybrid improvement are potential research directions in the future.

“…The computational results show that case G (eight-cell PCM unit geometry) quickly achieved complete melting 35.0% with respect to those in the triplex tube heat exchanger without fins. Al-Abidi et al [63] also investigated the same parameters reported in [62] on the solidification process of the PCM. Results reported that that case G (eight-cell PCM unit geometry) completed the whole solidification in 34.7% with respect to triplex tube without fins.…”

“…The HTF inlet temperature showed a large influence on the total charging time while the HTF flow rate had no effect on the system performance. Recently triplex tube heat exchanger (TTHX) using a triple concentric tube thermal energy storage system with PCM in centre tube has been studied [70][71][72][73][74][75][76]. The motivation of using a triple configuration is that an annulus shaped PCM layer in contact with the HTF from both inner and outer surfaces, provides a larger heat transfer area.…”
