Exergy analysis of a multi mixture working fluid absorption refrigeration cycle

Exergy analysis of a multi mixture working fluid absorption refrigeration cycle

This research paper analyzes the exergy of an absorption refrigeration cycle with a multi mixture working fluid selected as water and lithium-bromide. It relies on the fundamental thermodynamic principles, being chiefly the first and second laws. The exergy destructions have been obtained from diffe...
