Optimizing Waste Heat Recovery through TCF Networks
The study reveals that higher air flow rates significantly enhance total energy recovery, with effectiveness reaching around 30%. Increasing the heating temperature notably improves moisture recovery, reducing network sensitivity to liquid-to-gas (L/G) ratio variations. At 80°C, humidity ratio differences reach up to 4.3 g/kgda, and performance differences between L/G ratios become less pronounced.
Across all heating profiles (steady, Gaussian, RTO), the water removal to heat supplied (W/H ratio) decreases as the L/G ratio increases, indicating a decline in performance at higher desiccant flow rates. The Gaussian heating profile offers the highest W/H ratio at lower L/G ratios (peaking at 3.3 kg/kW at L/G of 0.2) compared to steady and RTO profiles, highlighting its effectiveness for transient heat sources.
AI-Based Simulator for Predictive Thermal Management
An Artificial Intelligence-based Multi-Layer Perceptron (AI-MLP) simulator was developed to accurately map the TCF energy network's dynamic performance. This simulator predicts key parameters like air humidity ratio difference (δωa) and moisture effectiveness (ɛm) based on input parameters such as time, L/G ratio, humidity ratio (HR), and temperature ratio (TR).
The simulator demonstrates strong predictive accuracy, particularly at lower L/G ratios and under Gaussian and steady heating profiles, with RMSE as low as 0.09 and relative errors around 2-4%. The use of a Bayesian regularisation algorithm was crucial in training the AI-MLP model, effectively mitigating overfitting and enhancing its generalization capability for real-world scenarios. This tool provides invaluable insights for operational strategies and system optimization.
