A new ejector refrigeration system with zeotropic mixtures
2011 (English)In: 23RD IIR INTERNATIONAL CONGRESS OF REFRIGERATION, 2011, 2043-2050 p.Conference paper (Refereed)
A new ejector refrigeration system (NERS) using zeotropic mixture is theoretical studied in the paper.R32/R134a, R32/R152a, R134a/R142b, R152a/R142b, R290/R600a and R600a/R600 are selected as theworking fluids in the analysis. The comparison between this NERS and the conventional ejector refrigerationsystem (CERS) is made under the same operating condition. It is found that this new system has higherCOPs than the CERS. The effect of operating conditions and the composition on the performance of this newsystem are presented. An exergy analysis is carried out to study the loss within each component of thesystem. It is observed that the irreversibility in the ejector represents more than 50% of the total exergy loss.This also emphasizes the necessity for good ejector design and manufacture.
