Abstract In this work, an experimental work was investigated on the nano-refrigerant. TiO 2 -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 TiO 2 -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 0.5 g/L TiO 2 -R600a nano-refrigerant. Thus, using TiO 2 -R600a nano-refrigerant in domestic refrigerators is feasible.
