Exergoeconomic analysis of a compression refrigeration cycle considering the allocation cost of the residue formation process

In this work, an exergoeconomic analysis is performed on a vapor compression refrigeration system using R134a. A productive structure is proposed and the exergetic and exergoeconomic costs balances are implemented with and without considering the components allocation costs of the residue formation process. A parametric analysis is carried out to evaluate the behavior of the exergetic and exergoeconomic operation costs, the coefficient of performance and the exergetic efficiency depending on the change in the ambient temperature, the refrigeration temperature, the adiabatic efficiency and the refrigeration capacity. The results show the system product costs (cooling effect) considering the residue costs is 56.8 % greater than the product cost obtained by discarding them. The parametric analysis shows that the exergetic and exergoeconomic operation costs are mainly affected by the change in the ambient temperature followed by the change in the refrigeration temperature
