Abstract

The operation of a Carnot heat pump is viewed as a production processwith exergy as its output. The short-run economic optimization ol theendoreversible heat pump is performed in this paper. The profit of the heat pump is taken as the optimization objective function. Using themethod of finite-time exergoeconomic analysis, which emphasizes the compromise optimization between economics (profit) and the utilization factor of energy (Coefficient of Performance, COP) for finite-time (endoreversible) thermodynamic cycles, this paper derives the relation between optimal profit and COP of an endoreversible Carnot heat pump based on a relatively general heat transfer law: q proportional to Delta(T-n). The COP bound at the maximum profit is also obtained. The results obtained involve those for three common heat transfer laws: Newton'sLaw (n = 1), the linear phenomenological law in irreversible thermodynamics (n = -1), and the radiative heat law (n = 4).
