Abstract: This paper deals with the analysis of the Cooling Loads (CL) of a solar absorption refrigerator. For this purpose, a new Process Conceptual Design (PCD) approach based on equivalent endoreversible model and hierarchical decomposition is developed. The influences of many cooling load aspects on the model performances are investigated. A sensitive study is made: performance coefficient (i.e. its inverse) vs. different cooling load aspects. New relationships between technical and economical criteria and optimal parameters stand out. An endoreversible new bound for the Inverse Specific Cooling Load (ISCL) is achieved. For every case, functional and practical domains are defined. Academic interest domains are also notified.

Keywords: absorption cycle; conceptual design; cooling loads; endoreversible cycles; hierarchical decomposition; solar absorption; refrigerators; exergy.
