Thermo-economic and environmental optimization of low-GWP HFO-based ORC systems using a hybrid Bayesian SVR-GWO framework
This study introduces a novel AI-driven optimization framework (Bayesian SVR-GWO) for Organic Rankine Cycles (ORCs) using low-GWP HFO fluids (R1233zd(E), R1234ze(Z)) as sustainable alternatives to R245fa for geothermal heat recovery. It demonstrates that R1233zd(E) offers superior thermodynamic performance (40.02% exergy efficiency) and significantly reduced environmental impact (99.8% TEWI reduction) with only a marginal cost increase (1.6%). The framework accelerates simulation speed by over 10,000 times, enabling comprehensive multi-objective optimization for green ORC plants.

This category highlights the core methodology of the study: optimizing ORC system performance. It details the use of a hybrid Bayesian SVR-GWO framework to conduct a comprehensive thermo-economic and environmental assessment. The goal is to identify optimal operating conditions and working fluids that balance efficiency, cost, and environmental impact. The framework significantly reduces computational time while maintaining high prediction accuracy, enabling rapid exploration of the design space for next-generation ORC plants.
This section focuses on the comparative analysis of working fluids. It evaluates hydrofluoroolefins (HFOs) like R1233zd(E) and R1234ze(Z) against conventional R245fa. The analysis includes thermodynamic properties, heat transfer characteristics, and, crucially, environmental impact (Total Equivalent Warming Impact - TEWI). The study aims to validate HFOs as technically superior and environmentally imperative successors, addressing the legislative pressures to phase out high-GWP HFCs. Findings show HFOs achieve comparable or superior performance with drastic reductions in global warming potential.
This category examines the innovative application of Artificial Intelligence in engineering design. It details the development and validation of a Bayesian-optimized Support Vector Regression (SVR) surrogate model coupled with a Gray Wolf Optimizer (GWO). This AI-driven approach replaces computationally intensive physics-based solvers, especially for conditions near the critical point where thermodynamic simulations are complex. The focus is on demonstrating how ML accelerates optimization, provides high predictive accuracy, and enables real-time design strategies for complex energy systems like ORC.
