Abstract :
The ejector expansion refrigeration cycle (EERC) is a variant of the standard vapor compression cycle in which an ejector is used to recover part of the work that would otherwise be lost in the expansion valve. In initial testing EERC performance was poor, mainly due to thermodynamic nonequilibrium conditions in the ejector motive nozzle. Modifications were made to correct this problem, and significant performance improvements were found
