This research paper reports an experimental analysis of phase change materials (PCMs) for thermal energy storage, emphasizing their thermal efficiency, material choice, and feasibility for energy efficiency systems. With this call for sustainable energy solutions growing, PCMs are coming up as a developing technique to boost energy storage, particularly in construction and industrial processes. With this study, a review of different PCM compositions is tested; organic, inorganic, and eutectic mixtures are displayed to determine their thermal properties, melting temperature, latent heat, and thermal conductivity. The experimental system was based on controlled heating/cooling cycles to test the thermal behavior of model PCMs under the actual working situations. The experimental results showed a considerable difference in thermal performance when different types of PCM were employed. Organic PCMs, e.g., paraffin wax, showed high thermal stability and latent heat, thus useful for recorded temperature applications. On the other hand, inorganic PCMs had annually higher thermal conductivity but were possible to phase separation, which can affect their long-term performance. Eutectic mixtures were also investigated; they show promise in scenarios that need a wider band gap temperature and better temperature management. It also assessed the effect of encapsulation techniques on the performance and durability of PCMs, emphasizing the significant importance of material selection to enhance thermal energy storage systems. This research is another puzzle of opportunity for all those related to PCMs under study. As mentioned, this is a review for all those researching thermal energy storage technologies. The results suggest that a suitable material must be chosen depending on the application requirement, especially the temperature range, thermal stability, and economical cost. This research intends to improve the use of PCMs in energy systems, increasing energy efficiency, minimizing dependence on fossil energy, and encouraging the deployment of renewable energy sources. The results of this work offer crucial information for researchers and engineers related to the topic, helping create a highly efficient and sustainable thermal energy storage for the period.

Liquid Thermo-Responsive Smart Window Derived from Hydrogel

This review article addressed the issues related to thermal efficiency increment and thermal performance investigation by usage of nanofluids and Phase Change Materials (PCM) as thermal performance enhancer and Thermal Energy Storage (TES) materials in Parabolic Trough Collectors (PTC). Also, the useful energy, exergy and the economic analysis utilizing PTC have also been explained and reviewed along with their applications. The different methods considered were experimental and some were numerical too. It was observed that, some of the nanofluids of metallic compounds like WS 2 , Al 2 O 3 , SiC, Fe 3 O 4 increased thermal efficiency by 31%, 35.7%, 30 and 40.41%. The usage of PCM like beeswax and paraffin wax as TES materials, led to increase in thermal efficiency by 54.04% and 85%. Exergetic efficiency increments of 5.49% was observed by the usage of Al 2 O 3 /SiO 2 -Syltherm 800 hybrid nanofluid also by using MXene/Syltherm 800 hybrid nanofluid the levelized cost of energy was low and was 0.1324/kW. The applications of PTC as Concentrated Solar Power (CSP) technology for electricity and steam generation, and industrial process heat have also been summarized. This work aids by finding different kinds of optimal nanofluid and optimal PCM along with their types (organic, inorganic, and hybrid) and kind of work (experimental or numerical) in which they are used and heat transfer efficiency increase Mechanisms. The novelty of such compact review article is that in single review articles the recent progress and technical advancements of past decades work on PTC is getting fulfilled holistically, earlier reviews were based on a single or combination of such isolated topics. Finally, the emerging and current applications in the field of hybrid systems are also elucidated. The techniques like Artificial Intelligence, Machine Learning, and Deep Learning applied on PTC for thermal performance prediction and fault detection are also discussed.

Form-stable paraffin/high density polyethylene composites as solid–liquid phase change material for thermal energy storage: preparation and thermal properties

In this study, a series of gelators (Gn, n is the number of carbon atoms of used fatty alcohol, n = 2, 4, 6, 8, 10, 12, 14, 16 and 18) were synthesized by reacting 4,4′-diphenylmethane diisocyanate with fatty alcohols. Meanwhile, n-octadecane-based gels as form-stable phase change materials (FSPCMs) for thermal energy storage were prepared by introducing Gn into n-octadecane. The gel properties were confirmed by “tube testing method.” The results show that Gn (n = 2, 4) were immiscible with n-octadecane, while a lower mass percentage content (≤ 6 mass%) of Gn (n = 6, 8, 10, 12, 14, 16, 18) can gelate the n-octadecane and the gel-to-sol transition temperature is higher than 100 °C. The chemical structures, morphologies and crystalline properties of prepared FSPCMs were determined by Fourier transform infrared spectroscopy, scanning electron microscope, X-ray diffraction and polarized optical microscope. It is found that Gn could self-assemble into lamellar three-dimensional network structure to restrict the leakage of melted n-octadecane. Differential scanning calorimetry analysis results indicate that prepared FSPCMs exhibit high latent heats and latent heat efficiency is greatly higher than that of other traditional FSPCMs. Moreover, thermal cycling test results confirm that the prepared FSPCMs have good thermal reliability and reusability. This study is attractive for preparation of FSPCMs with high latent heats. Prepared FSPCMs could be potentially applied in the field of thermal energy storage for thermal comfort.
