Résumé

The use of non-azeotropic mixed refrigerants is becoming of greater interest due to the phase-out of CFCs, and the lack of suitable environment-friendly pure alternatives. Refrigeration systems may use either pool- or flow-boiling evaporators. Whilst the use of mixtures in flow-boiling systems has been the subject of a significant amount of research, little attention has been paid to pool-boiling systems. The article considers this issue, and identifies a reduction in efficiency that occurs as a result of using mixtures in place of pure fluids. The cause of this problem is examined, and a number of alternative system configurations are evaluated. It is concluded that, in pool-boiling cycle, a mixed refrigerant will always result in a poorer efficiency than is obtainable with a pure fluid.
