Prediction of performance of a jet cooling system operating with pure refrigerants or non-azeotropic mixtures. Influence de la nature des fluides, purs ou en melanges non-azeotropiques, sur les performances d'une machine de climatisation a ejecto-compresseur

Abstract

This paper investigates a simple model of an ejector-compression refrigeration cycle and its applications to air conditioning. The efficiency using either classical refrigerants (R11, R22, R114), other pure refrigerants (R123, R133a, R134a, R141b, R142b, R152a, RC318) or non-azeotropic mixtures is presented. The results suggest that, for different temperatures of the heat source and the heat sink, the entrainment ratio and the system efficiency depend mainly on the fluid type and the mixture composition. An exergetic analysis shows that the major part of the exergy destruction takes place in the ejector, but that the boiler and condenser exergetic losses are significant. (author)
