This study presents a novel technique to enhance the efficiency of these cycles by integrating a thermoelectric subcooler tailored to Jordan's climate. The transcritical CO₂ refrigeration cycle, with a nominal refrigeration capacity of 14 kW, was modeled using engineering equation solver software. A key aspect of this study is the incorporation of solar energy through a custom-designed photovoltaic (PV) system to power the refrigeration cycle, contributing to sustainable cooling technology. Key performance indicators, including refrigeration capacity, power consumption, and coefficient of performance (COP), were thoroughly investigated across varying parameters, such as gas cooler pressure (8000–13,000 kPa), evaporation temperature (−15°C to 15°C), ambient temperature (28°C–35°C), current supply (5–15 A), and the number of thermoelectric pairs (50–150). Results showed that increasing the gas cooling pressure increased refrigeration capacity by approximately 79%. At a gas cooling pressure of 9000 kPa, the thermoelectric subcooler increased refrigeration capacity by 55%. Increasing the evaporation temperature improved the COP by approximately 133% and reduced power consumption by 68%. At an evaporation temperature of −15°C, the thermoelectric subcooler improved performance by 12%. Lowering the ambient temperature also enhanced COP by 68% and reduced the power consumption by 35%. At a 35°C ambient temperature, the subcooler improved COP by 8%. Experimental validation showed a 6% average deviation between simulation and experimental results for COP. The on-grid PV system designed with PVsyst software successfully met the cycle's energy demands, achieving 45.3% energy savings.</p>\u0000 </div>","PeriodicalId":44939,"journal":{"name":"Heat Transfer","volume":"54 4","pages":"2865-2880"},"PeriodicalIF":2.8,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The governing nonlinear partial differential equations are transformed into nonlinear ordinary differential equations through an appropriate similarity transformation. These equations are subsequently solved using the semi-numerical Differential Transform Method. To validate the accuracy of the DTM, the computed results for skin friction, the Nusselt number, and the Sherwood number are meticulously examined through graphical visualizations and tabular comparisons with numerical solutions. Additionally, a residual squared error analysis is conducted to further confirm the precision of the employed method. The findings indicate that increasing the Brownian motion and thermophoresis parameters leads to a pronounced enhancement in thermal profiles, while concentration profiles exhibit distinct contrasting trends.

The study uniquely combines flow past a wavering tilted porous plate, hydromagnetic flow with varying magnetic field inclinations, and the interplay of viscous dissipation and the Dufour and Soret effects. The model's nonlinear flow managerial dimensional PDEs were renewed into nonlinear dimensionless PDEs and solved using an effective finite element technique. The velocity, temperature, and concentration distributions are analyzed graphically counter to the most significant pertinent parameters of the model, and the skin friction, heat, and mass conveyance rates are deliberated by the tabular data at the surface using MATLAB software based on numerical solutions. The results depicted that higher viscous dissipation, heat source, permeability, and Soret and Dufour parameters expand the velocity distribution. The opposite conduct was realized in the velocity distribution due to the radiation, magnetic field strength, plate inclination angle, and aligned magnetic field. The heat causes viscous dissipation, and Dufour effects are triggered to enlarge temperature distribution, but it drops with thermal radiation. The concentration field is sustained by the time factor and the Soret effect but decays with the influence of chemical reactions. Further, the skin friction improved at the surface by the permeability parameter, while the plate tilt angle and devoted magnetic strengths hindered the skin friction. The mass transfer rate grows with chemical processes but decreases with thermo-diffusion. The heat transfer rate grows at the surface with time and thermal radiation conditions. Considerably, integrating these diverse physical parameters in a single numerical study provides new insights into their combined effects on flow fields, contributing to advancing the knowledge of the hydromagnetic fluid flow performance under various influences in the porous media.
