Abstract: This study presents an exergetic examination of a vapour compression refrigeration system.The exergetic balance conditions have been defined.Experimental work depending on the change of the capillary tube length (800, 1000, and 1200) mm with refrigerant mass flow rate changes from (10.3 to 21.3) kg/hr has been done to represent the different exergy flow occurring in the system components.The results were compared for each condenser temperature, evaporator temperature, coefficient of performance, exergy losses, exergy efficiency, efficiency defects, and rational efficiency.Results have been presented graphically.The finding indicated that the coefficient of performance decreased by 7% as the capillary length increased from 800 to 1200 mm.Also, the total exergy increases by 2.3% with increasing mass flow rates.
