Performance study of a domestic refrigerator using CuO/AL₂O₃-R22 nanorefrigerant as a working fluid

This work is a performance study that investigated the nanorefrigerant CuO/AL2O3-R22 used in a refrigerator without any remodelling of the system. The refrigerator performance was then investigated using energy consumption test and enhancing heat transfer rate. The heat transfer enhancement was investigated on the surface of a refrigerator by using the nanorefrigerant Al2O3/CuO. The results indicate that CuO-R22 works normally and safely in a refrigerator and has better power consumption and heat transfer rate. Thus, using CuO-R22 as nanorefrigerant in domestic refrigerators is feasible for better heat transfer rate.
