Résumé

The efficiency of magnetic refrigeration systems, a sustainable alternative to conventional cooling technologies, depends heavily on the heat transfer fluid. This work analyzes an active magnetic regenerator that uses a 30% mass mixture of water and propylene glycol, subsequently enriched with various nanoparticles (Al₂O₃, CuO, fused-SiO₂, TiO₂, α-SiO₂, ZnO, SiC). The thermophysical properties of the nanofluids were determined using empirical correlations, and their impact on system performance was evaluated using a dedicated model. The results show that volumetric concentration and particle size are the key parameters: an increase in concentration and a reduction in particle size significantly improve cooling capacity, albeit with a reduction in the coefficient of performance. The material of the nanoparticles, on the other hand, has a relatively minor influence on overall thermal performance. These conclusions provide useful insights for optimizing nanofluids in magnetic refrigeration.
