Abstract

In the current paper, a new configuration of the ejector-vapour compression refrigeration cycle was presented, which uses an internal heat exchanger and intercooler to enhance the performance of the cycle. The theoretical analysis on the performance characteristics was carried out for this new cycle based on the first and second laws of thermodynamics. The effects of the evaporative and condenser temperatures on the coefficient of performance (COP), second law efficiency, exergy destruction rate and entrainment ratio were investigated. The exergy analysis is employed in order to identify the amounts and locations of the irreversibility within the cycles. It was found that the COP and second law efficiency values of the new ejector-vapour compression refrigeration cycle are on average 8.6 and 8.15 per cent higher than that of the conventional ejector-vapour compression refrigeration cycle with R125. It was also shown that the COP of the new ejector-vapour compression cycle is 21 per cent higher than that of the conventional vapour compression.
