The increasing demand for energy, driven by urbanization and industrialization, raises concerns about energy depletion and its impact on industrial development. Among household appliances, refrigerators stand out as significant energy consumers. Despite their widespread use, they require substantial electrical energy for continuous operation. Addressing this issue necessitates the adoption of more efficient energy-saving techniques, particularly those focused on enhancing the heat transfer capability of refrigerants. It is observed that nanorefrigerants represent a promising avenue for achieving these goals. By incorporating nanoparticles into traditional refrigerants, nanorefrigerants have the potential to significantly enhance heat transfer properties, improve efficiency, and reduce environmental harm. This research aims to lies in unlocking the full potential of nanocomposite refrigerants within VCR systems. The objectives of this research are to characterize nanocomposite refrigerants, evaluate their performance in VCR systems, and analyze the influence of nanocomposite refrigerants. In the present work, two different nanoparticles such as ZnO and Al2O3 are used and the concentration of nanoparticles were varied in the lubricant to determine the effect of nanoparticles on the lubricant properties and performance of refrigerator. The maximum concentration of nanoparticles varied in the lubricant is 0.02 g. The properties of nanolubricants such as specific heat, thermal conductivity, density, and kinematic viscosity were determined at temperature 35 ºC. Furthermore, effect of nanolubricants on COP of refrigerator was observed. By this investigation, 27.9% improvement in COP has been achieved in R1234yf with Al2O3 and ZnO hybrid nanocomposite as compared with the pure lubricant vapor compression refrigeration system.
