Evaluación de un Sistema de Refrigeracióôn usando la Termodinámica Endorreversible

This paper describes the use of endoreversible thermodynamics to evaluate the behavior of a mechanical compression refrigeration system. The coefficients of performance of the endoreversible Carnot Cycle, COP_CE. were obtained by including the external irreversibility associated with heat transfer. The real coefficient of performance (COP_R), the reversible Carnot coefficient of performance (COP_C) and the endorreversible Carnot coefficient of performance (COP_CE) were determined using experimentally obtained pressures and temperatures. The results were compared with experimental data from a laboratory refrigeration system, and the conclusion was that the COP_CE was the parameter of choice for setting the theoretical limits for refrigeration system operation instead of the COP_C as has been conventionally done.
