Photovoltaic (PV) panels are experiencing significantly reduced performance and lifespan because of the harsh operating conditions in desert locations. This study presents a novel approach for implementing a closed-loop hydronic PV cooling method, integrated with an underground water tank functioning as a ground heat exchanger in soil, to address the challenges of overheating of PV cells during o…

Zeotropic refrigerant mixtures are promising alternatives to high–global warming potential fluids due to their thermodynamic flexibility and temperature glide, which enables improved thermal matching in heat exchangers. However, the non-isothermal phase change and associated mass transfer effects introduce strong non-equilibrium behavior that challenges accurate prediction of flow boiling heat tr…
