ABSTRACT = {This work involves an experimental study on the performance of automobile air-conditioning systems by adding Al<sub>2</sub>O<sub>3</sub> nanoparticles to oil compressors to investigate their impacts on the enhancement of the speed cooling of refrigeration systems and to compare it with the system operated using only oil. The Al<sub>2</sub>O<sub>3</sub> nanoparticles have been added to the oil compressor for different ranges of mass concentration (Ø = 0.1%, Ø = 0.15% and Ø = 0.2%). The stability of Al<sub>2</sub>O<sub>3</sub> nanoparticles has been tested by direct observation for different time periods. The results indicated that the air conditioning system that operated by using Al<sub>2</sub>O<sub>3</sub>-oil was better than the system that operated with pure oil. For Ø = 0.2%, the results indicated that the cooling speed and the efficiency of the system operated with Al<sub>2</sub>O<sub>3</sub>-oil are increased by 13% and 18%, respectively, as compared to the pure oil system. This study shows that the thermos-physical properties of refrigerant oil are enhanced by 15% when Ø is increased.},
