This study aims to determine the performance improvement of a vapor compression systems that use expansion parallel liquid refrigerant. The experiment was conducted by replacing the single expansion device with a parallel expansion device on a vapor compression systems. The working fluid is used as a cooling medium is R-290. To get performance data, measurements performed on the cooling load with various temperatures (range from 3C to - 3C). Finally, The results showed that expansion parallel liquid refrigerant on a vapor compression systems generates an increase in refrigerating efect and COP of 49% and 2,5%, respectively. This has implication to saving the power consumption of the vapor compression systems. © Published under licence by IOP Publishing Ltd.
