Avantages d’une configuration de machine à absorption opérant à trois niveaux de pression

Abstract: Cetteétude présente une machine frigorifique fonctionnant suivant un cycleà compressionabsorption. Le système proposé utilise le couple ammoniac-eau comme fluide frigorigène et opèreà trois niveaux de pression. L'absorbeur fonctionneà une pression intermédiaire Pint, prise entre la pression de l'évaporateur (PEV) et celle du condenseur (PCD). Les principauxéléments du système proposé sont modélisés. Les résultats de la simulation numérique sont comparésà ceux relatifs au système conventionnel. L'étude comparat… Show more

“…The cascade cycle (cascade 1) and double stage cycle (cascade 2) represented respec- tively in Figs. 2 and 3 are developed by Bouaziz et al [14,15,27]. The new cycle evaporator-compressor-absorber (ECA) is composed by an evaporator, absorber, generator, condenser and a compressor inserted between the evaporator and the absorber.…”

“…Other models composed of different stages with different associations between the system components; they worked at three pressure levels, Saghiruddin and Siddiqui [13], Bouaziz et al [14][15], Charia et al [16] and Kumar [17]. There is a wide range of refrigerant couples that can be used for the refrigerating machine such us NH 3 /H 2 O, NH 3 /NaSCN and NH 3 /LiNO 3 , Rodakis and Antonopoulos [18], Linghui Zhu and Junjie Gu [19], Kairouani et al [20], and S. Anand et al [21].…”
