Summary

The jet flow development inside an ejector in a compression/ejection refrigeration cycle was investigated. The flow processes along the flow path inside the ejector were modelled including pressure adjustment, jet mixture, equalization, and diffusion. The computing results are consistent with the experimental data. The entrainment ratio, outlet pressure, and energy-saving effect increase with the increase in condensing temperature in the compression/ejection refrigeration cycle. Moreover, there is an optimum evaporating temperature at which the entrainment ratio is greatest and the outlet pressure is higher.
