A new ejector-absorber cycle to improve the COP of an absorption refrigeration system

  • Chen, Li-Ting

Abstract

A modified ejector-absorber absorption refrigeration cycle is presented and analysed. Results for an R-22/DME-TEG system with a 0·5 heat-exchanger effectiveness and a 0·85 nozzle (diffuser) efficiency are computed for the conventional as well as the modified cycle. A considerable improvement in COP is observed for the latter.
