Abstract: “The transportation industry is no doubt a fast growing industry globally. In the recent years, the use of nano fluids have been proposed in the refrigeration and air-conditioning system as primary, secondary fluids and lubricants to enhance the performance of the system. This present study focuses on the use of TiO2 and SiO2 nano lubricants to improve the performance of the vapour compression system. Pure mineral oil was used as the base fluid and the performances were compared with that of the TiO2 and SiO2 nano lubricant using R600a refrigerant as the working fluids in the system. The result showed that R600a performed better in the nano lubricant compared to the base lubricant in terms of coefficient of performance, power consumption and the cooling capacity of the system.”
