Contribution à l'étude et l'optimisation thermodynamique et thermoéconomique des machines à froid

Abstract : This work represents the results obtained within the context of the author's Ph.D. study with regard to the thermodynamic and thermoeconomic optimisation of refrigeration cycles. In the first part, endoirreversible models of four reservoirs refrigeration cycle are developed. The study relates, firstly, to the maximisation of the coefficient of performance of the refrigeration machine; then to the maximisation of the exergetic efficiency of a heat transformer without constraints and for various constraints. At the end of this part, a comparison of each studied objective is proposed. In the second part, stationary dynamic models for three types of refrigerating machines (compression, absorption and compression-absorption) are developed. The energetic system is analysed, firstly, from the energetic point of view and then from the economic standpoint in order to predict a rational use of energy, more powerful machines or less expensive machines.
