Abstract

This paper experimentally explored energetic and exergetic performance investigation of VCR System using Ag₂O-R134a Nanofluid as Refrigerant. The integration of silver oxide (Ag₂O) nanoparticles within polymer and composite materials offers promising avenues for enhancing the thermal and physical properties of advanced systems. The energetic and exergetic performance study of VCR were investigated with test parameters including compressor power consumption, cooling capacity, coefficient of performance (COP), discharge temperature, irreversibility in the components, total irreversibility and second law efficiency. Findings presented that the lowest compressor power consumption and total irreversibility were observed in refrigerator with 80.5 g charge of total mass mixture (grams)Ag₂O/ R134a (10.5 g/L of R134a); these values of compressor power consumption and total irreversibility were 15.87% and 31.69% respectively, lower than for R134a refrigerant. In addition, the VCR system using refrigerant at 80.5g charge with) Ag₂O/ R134a (10.5 g/L of R134a), had the highest COP and second law efficiency among the selected nano-Refrigerants. These values of COP and second law efficiency were 56.32% and 47.06%, higher than that of Ag₂O/ R134a (80.5g/L of R134a). Furthermore, compressor discharge temperature of the domestic refrigerator with R134a was found to be lower than that of Ag₂O/ R134a (10.5 g/L of R134a).

Keywords: Ag₂O, cop, energetic, nanofluid, second law efficiency, vapor compression refrigeration.
