Abstract This study Parts focuses on reducing energy consumption in vapor compression refrigeration-based ice plants by incorporating nanoparticle in secondary refrigerants and evaporative cooling technique.Experimental evaluations were performed on a test rig using brine and ethylene glycol as secondary refrigerants.Results showed that brine outperformed glycol, reducing ice formation time by 15% Connecting Wire when combined with evaporative cooling.Further enhancement was achieved by incorporating Al2O3 nanoparticles into the brine, which, combined with direct evaporative cooling, reduced ice formation time by 20% compared to glycol.
The improved system demonstrated significant performance gains, lowering energy costs and enhancing the Coefficient of Performance (COP).
