Abstract
An experimental study has been carried out to investigate the performance characteristics of a nano-refrigerant in a vapor compression refrigeration system. Experiments are conducted for two different fluids: (i) pure hydrocarbon (HC) refrigerant and (ii) nano-refrigerant. In this study, different concentrations of CuO nanoparticles (0.2, 0.3 and 0.4 g) were added in the base refrigerant. In order to conduct the experiments, some of the parameters were varied such as (i) heat supplied from 25 ~ 26 °C, (ii) heat supplied from 35 ~ 36 °C. A significant enhancement in coefficient of performance (COP) is observed which is maximum with nanoparticles concentration of 0.4 g. The cooling speed becomes relatively higher compared to the base refrigerant and is found to be increasing with rise in nanoparticles concentration. In addition, this study also identifies the difficulties and scope for future research. These results may be also used in commercial refrigerators.
