Résumé

A vapour ejector refrigeration system has a better performance when the ejector operates in choking mode. A computer code based on the existing one-dimensional ejector theory has been developed to carry out a study on the performance of the system. When operating conditions are changed, the critical performance parameters of the system shift to different critical values. The code includes the effects of change in specific heat of the working fluid and friction in the constant-area mixing chamber besides the internal irreversibility of the ejector. The simulated performance results are compared with the available experimental data from the literature for validation. The effects of operational parameters and ejector configurations of the system on critical performance are studied. Also, comparison of the performance of the system with environmentally friendly refrigerants, R134a, R152a, R290, R600a and R717, is made.
