The paper provides experimental studies on the possibility of improving the cooling efficiency of a split air conditioning system through the application of advanced lubrication technology. The efficiency of the system is compared to the situation when using three types of lubricants: conventional Pure oil, a mono-particle nano-lubricant (Al2O3), and a hybrid nano-lubricant (Al2O3- SiO2). This experiment employed concentricity 0.025 percent of (Al2O3) nano and (Al2O3- SiO2). hybrid nanofluid, which has been incorporated into the air conditioning compressor oil. The cooling capacity, compressor work, and the coefficient of performance (COP) were considered as key performance indicators that were tested under controlled experimental conditions. The findings indicate that the concentration of nanoparticles in the lubricant improves the thermo-physical characteristics and heat transfer of refrigeration cycle. Although both the nano-lubricants performed better than the conventional oil, the hybrid nano-lubricant demonstrated the most evidence of improvement reporting a significant rise in the COP as well as a significant decrease in the consumption of energy. The results indicate that hybrid nano-lubricants can be used to a considerable degree to enhance the energy efficiency of vapor compression refrigeration-based systems.
