Popis:	Vapor compression cycle is mainly employed as a refrigeration cycle in the Air-Conditioning (AC) unit. In order to save energy, the Coefficient of Performance (COP) of the need to be improved. One of the potential solutions is to modify the system into the multi-stages vapor compression cycle. The present work deals with the investigation of single-stage and multi-stage vapor compression refrigeration cycle. A typical vapor compression cycle that is used in the AC unit is taken into consideration. The used refrigerants are difluoromethane R32. The analysis using the simulation process by utilizing software Aspen One. The performance parameters includes COP, the mass flow rate of the refrigerant and compressor power. It was shown that there exists a maximum COP for multi-stage. By taking these performance simulation results the multi-stage is the efficient method for the air conditioning system.
