Abstract: Utilisation of an ejector as an expander was experimentally investigated for an expansion work recovery in a basic refrigeration cycle. Exergy analysis was used to determine the amounts and locations of irreversibilities in the elements of the ejector expansion refrigeration system. It was seen that the ejector refrigeration cycle indicated a lower exergy destruction and a higher exergy efficiency compared to the vapour compression refrigeration cycle for each working condition. It was obtained that the values for the irreversibility of the ejector refrigeration cycle were less than in the vapour compression refrigeration cycle by 5.9-12.6% and the exergy efficiencies of ejector refrigeration cycle were 6.7-14.2% more than in the vapour compression cycle.
