A thermodynamic model of ejector was established by introducing refrigerant property.The change in pressure and temperature in the ejector and the entrainment ratio of ejector for several refrigerants with similar normal boiling point were compared
and the difference in injector performance was analyzed according to refrigerant properties.The refrigeration performances of several pairs of refrigerants with similar normal boiling points were also compared.The results indicate that higher specific enthalpy of driving vapor results in higher entrainment ratio of ejector.Among the refrigerants studied
R717 gives the best performance and R152a takes the second place
and their COP difference increases with generation temperature.
