Public ISBD [article]  in International journal of refrigeration > Vol. 34 N° 1 (Janvier 2011) . - pp. 292-302 Titre : Investigating performance of microchannel evaporators with different manifold structures Titre original : Etude sur la performance des évaporateurs à microcanaux des collecteurs de structures différentes Type de document : texte imprimé Auteurs : Junye Shi, Auteur ; Xiaohua Qu, Auteur ; Zhaogang Qi, Auteur Année de publication : 2011 Article en page(s) : pp. 292-302 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Microchannel  evaporator  Flow  distribution  Experimentation Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : In this paper, the performances of microchannel evaporators with different manifold structures are experimentally investigated. Eight evaporator samples with 7 different designs of the I/O manifold and 5 different designs of the return manifold are made for this study. The performances of the evaporator samples are tested on a psychometric calorimeter test bench with the refrigerant 134A at a real automotive AC condition. The results on the variations of the cooling capacity and air temperature distribution of the evaporator due to the deflector designs in the I/O manifold and flow hole arrangements in the return manifold are presented and analyzed. By studying the KPI’s for the performance of an evaporator, the design trade-off for an evaporator designer is summarized and discussed.
