The integration of photovoltaic (PV) system in power proved to be potential technology terms renewable energy sources. However, has major drawback rise cell temperature, which results low production and reduced service life. To overcome the temperature system, addition water cooling phase change materials installed at rear side PV termed as thermal (PVT) been adopted this study. organic material (RT-42) having melting 42 ℃ running 0.45 litre per minute (LPM) under 440 W/m 2 irradiation taken input parameters. cooled performance analysed by using real time solar simulator. Additionally, PVT-PCM is assessed use TRNSYS simulation. Finally, study compares electrical efficiency PV, PVT, systems. findings indicated that maximum for cells a was 59 ℃. Water alone reduces down 49 ℃, whereas combined with (PVT-PCM) lowers it 36℃. Further, heat gain 189 watt 191 achieved PVT system. systems efficiencies 6.1%, 7%, 9.5%, correspondingly.

Low thermal conductivity and liquid phase leakage impede the widespread adoption of change materials (PCMs). To enhance PCM performance practical viability, addressing these limitations is crucial. Current study addresses low issues. Enhanced in PCMs achieved by adding graphene nanoplatelets (GnPs), while expanded graphite (EG) acts as a leak‐proof barrier. The composite (ss‐NePCM) developed ultra‐sonication followed vacuum impregnation process. samples underwent comprehensive analysis: (TEMPOs), chemical composition (FTIR), photo‐transmittance (UV–Vis), stability (TGA). results show that with 0.6 wt% GnP (NePCM 3 ) has highest enhancement ≈112% 15 EG (ss‐NePCM diminishes problem. According to optical assessment, exhibits notable increase absorbance 116% higher than base PCM. However, due introduction additives, differential scanning calorimeter (DSC) detected minor variation from 154 144.76 J g −1 latent heat. Furthermore, demonstrates reliability following 250 heating cooling cycles. ss‐NePCM holds promise for systems, where could jeopardize system integrity.

Heat is involved in many processes the food industry: drying, dissolving, centrifugation, extraction, cleaning, washing, and cooling. generation encompasses nearly all processes. This review first presents two representative case studies order to identify which rely on major energy consumption greenhouse gas (GHG) emissions. Energy-saving decarbonating potential solutions are explored through a thorough of technologies employed refrigeration, heat generation, waste recovery, thermal storage. Information from industrial plants collected show their performance under real conditions. The replacement high-GWP (global warming potential) refrigerants by natural fluids refrigeration sector acts lower GHG Being greatest consumers, compared using levelized cost (LCOH). analysis shows that absorption transformers high-temperature pumps most interesting economic decarbonation points view, while recovery present shortest payback periods. In sectors, efficiency improvements components, storage technologies, polygeneration systems, concept smart industry, penetration renewable sources appear as valuable pathways.

<p>With the prosperity of electric vehicles (EVs), thermal management lithium-ion battery (LIB) is crucial for ensuring safety drivers on EVs. Composite phase change material (CPCM) with high latent heat has a great promising prospect in systems (BTMS). However, efficiency CPCM limited due to leakage, low conductivity and flammability. Herein, novel multifunctional paraffin (PA), epoxy resin (ER), expanded graphite (EG), methyl MQ silicone (MQ) melamine phosphate (MP) (PEE/MQ/MP3) been prepared, which can achieve well anti-leakage, flame-retardant conductivity, enhancing module. The results reveal that PEE/MQ/MP3 MP at ratio 1:2 exhibit optimum flame retardant performance. total release peak, smoke production rate, carbon monoxide dioxide are 169 MJ/m², 0.05 m²/s, 0.005 g/s 0.38 g/s, respectively. module displays excellent performance, delaying propagation. Even after ten cycles 3 C maximum temperature controlled below 50 ��C difference maintained 5 ��C. Besides, propagation processes modules absorb transfer first stage timely quickly, efficiently suppressing hazard occurrence. Therefore, this study proposed as an effective solution enhance modules, thus EV drivers.</p>
