Finite time thermodynamics cannot be dissociated from thermoeconomics since the constraints applied to geometric, thermodynamic or time factors have a direct impact on the cost equation of an energetic system. In this study, the authors have conducted a comparative thermoeconomic optimization of a heat pump based on a finite time thermodynamics approach where the objective function is respectively the energy performance coefficient, COP, the exergy performance coefficient, {eta}{sub ex}, and the cost performance coefficient, {eta}{sub ec}. The optimization problem consists of an objective function, as defined above, thermodynamic constraints, technical constraints, and a constraint on the total external heat transfer area. A sensitivity analysis is conducted with respect to the total external heat transfer area.
