Comparaison de deux approches d'optimisation. Application à une thermopompe

Abstract : Comparison between two optimization approaches. Application to a heat pump. An energy flux consists of two parts; an available part, the exergy, and a non-available part, the anergy. The functional diagram of an energetic system is a schematic representation of fluxes for these two compounds. On this diagram, we define the products and ressources of exergy and anergy for each unit of the system as interactions with the external environment and/or with an internal network using two loops: an exergy loop and an anergy loop. This internal circuit could be represented by a server managing the use of exergy and anergy by the various units of the system. We associate to the exergy and anergy fluxes, unit costs defined through an approach called decomposition [l]. This study is concerned with the comparison of results when optimization is based on an objective function, that is on one side the investment cost of the system and on the other side the coefficient of performance (COP). In both cases, the work downstream consists in optimizing the unit cost of the main product of each component using the decomposition approach. We will compare the COP, the investment cost, the annual cost and the thermodynamic states of the system.
