Prediction of Saturated Vapor Density of Refrigerant Mixtures[J]. Journal of Refrigeration, 2007, 28(3): 36-39. DOI: 10.3969/j.issn.0253-4339.2007.03.008.
it is found that the relationship between saturated vapor corresponding - density and corresponding- temperature for mixtures accorded with that for pure- components. Moreover
a methed was obtained to calculate the critical density and critical pressure of refrigerant mixtures by using the critical density and critical pressure of pure- components and thus the characteristic parameters
the critical density and critical pressure of refrigerant mixtures
were achieved. Then the generalized equation that is implicit and used to calculate saturated vapor density of refrigerant mixtures was proposed. In addition
the values calculated were compared with the values in literature for five ternary and binary refrigerant mixtures and their deviation is less than 2%.
