ABSTRACT
An Air-Cooled Chiller system (ACCs) that is designed to work with R-22 was used as a test unit to assess the possibility of using hydrocarbons as a refrigerant. Pure propane, namely R-290, was used as a refrigerant. The purpose of this study was to determine the performance of air-cooled chiller systems using hydrocarbon R-290, which contains pure propane. The performance of the ACCs using hydrocarbons as a refrigerant was investigated and compared with the performance of ACCs when R-22 was used as a refrigerant. The effect of the discharge pressure and suction pressure on the refrigerating effect, a heat of compression and Coefficient of Performance (COP) were investigated. Finally, the COP and other results obtained in this experiment can provide a positive indication of using hydrocarbons as a refrigerant in the ACCs.
