Abstract A new hybrid refrigeration cycle of the Mixed-refrigerant Auto-Cascade J-T cycle combined with a vortex tube is introduced. This cycle, which holds the advantage of a mixed refrigerant Auto-Cascade J-T cycle and the vortex tube, is expected to achieve a temperature lower than 65 K. A thermodynamic model is used to investigate the vortex tube energy separation. The exergy method is applied to analyze the thermodynamic performance of each unit and the whole refrigeration cycle. A comparison is made between the Auto-Cascade J-T cycle and the new hybrid refrigeration cycle for the same conditions. The total exergy efficiency achieved in the new hybrid refrigeration cycle is 78.9% better than the Auto-Cascade J-T cycle. The results show that using the new type of compound refrigeration cycle can improve exergy efficiency of the whole cycle. It is completely possible to achieve a temperature lower than 65 K.
