| Sumario: | In this paper, a thermodynamic analysis and an exergoeconomic analysis were applied to vapor compression refrigeration cycle with refrigerant HFC-134a. The thermodynamics properties of the each state of the system were calculated and a parametric analysis of the coe cient of performance, the exergetic e ciency, the power input to the compressor and the mass flow rate of HFC-134a was performed for a given refrigeration capacity. The productive structure of the equipment of the system was generated; in addition, an exergoeconomics analysis was made. We obtained the resources, products and the irreversibilities of each equipment, the exergetic operation cost and the exergoeconomics operation cost in function of the environmental temperature and the refrigerated spaced temperature. For the Mexican Republic, the variation of the environmental temperature ranged between 20 o C and 35 o C in average. For this interval of temperatures and atmospheric pressure of 1 bar, refrigerated spaced temperature of -5 o C and for a refrigeration capacity of 5 TR, the coe cient of performance of the refrigeration cycle was 6.5 to 4, the exergetic e ciency was 49 to 30%, the exergetic operation cost was 4.5 to 10 kW and the exergoeconomic operation cost was 3.7 to 8.5 $ / hr. |
