Optimization of Combine Heat Pump and Cogeneration System under Alternative Performance Criteria

In this study, a performance analysis based on alternative performance criteria has been performed for a reversible Carnot and heat pump cycle, modified for cogeneration, with external irreversibilities. The optimum values of the design parameters of the new cogeneration cycle were determined for different criteria. In this context, the effects of design parameters on the exergetic performance are investigated, and the results are discussed. The obtained results may guide towards a more realistic criterion for actual combine heat pump and cogeneration plants.
