Enhancing Benefits by Rectification in the Absorption Refrigeration Systems

The main objective of this article aims to enhance a single stage absorption refrigeration machine, using the ammonia-water pair as working fluid, and from improvement its exergetic performances by means vapor rectification system. rectifier makes it possible emit enriched in pure fluid (ammonia) with high flow rate; one is thus transformed into condensate after condensation; also allows evacuating liquid (water) form reflux. Moreover, order show role highlight impact on operation proposed installation, methodology adopted work develop thermodynamic model numerical simulation FORTRAN language according two approaches. An energetic analysis approach which assess, first time, performance studied installation. However, tries calculate exergy efficiency, evaluate losses exergies installation second time. Therefore, obtained results showed clear accompanied against an optimization are due irreversibility novelty brought present study encourages engineers manufacturers realize future machines integrating systems.
