Performance of a domestic refrigerator using TiO2-R600a nano-refrigerant as working fluid

Abstract: In this work, an experimental work was investigated on the nano-refrigerant. TiO2-R600a nano-refrigerants were used in a domestic refrigerator without any system reconstruction. The refrigerator performance was then investigated using energy consumption test and freeze capacity test. The results indicate that TiO2-R600a nano-refrigerants work normally and safely in the refrigerator. The refrigerator performance was better than the pure R600a system, with 9.6% less energy used with 0.5g/L TiO2-R600a nano-refrigerant. Thus, using TiO2-R600a nano-refrigerant in domestic refrigerators is feasible. [ABSTRACT FROM AUTHOR]
