Thermo-economical analysis between new absorption-ejector hybrid refrigeration system and small double-effect absorption system

摘要

The comparisons of coefficient of performance and the cyclic characteristics between the three-pressure absorption-ejector hybrid refrigeration system (AEHRS) and small double-effect absorption refrigeration system are carried out. The thermo-economical analysis models of the two systems two cases of high-temperature heat resources: waste heat resources and natural gas fuel are presented. The thermo-economical performances of the two systems in two modes of the running hours per year (600 and 1000 h) are calculated and discussed tow show the commercial perspective of the AEHRS.
