Calculation of the boiling density of new refrigerants and refrigerant mixtures with transformed volumetric equation of state.

[In German. / En allemand.]

Author(s) : NAGEL M., BIER K.


The calculation method has been verified with measurement values of the boiling density literature for seven pure refrigerants (R32, R125, R134a, R143a, R152a et R22 et R142b), seven binary mixtures (R125-R143a, R143a-R134a, R32-R134a, R32-R125, R22-R152a, R22-R142b et R134a-R152a), and a ternary mixture of R125, R143a and R134a. For a given temperature field the differences between the calculated and the measured boiling densities for the pure refrigerants are generally under 0.5% and for the mixtures the most often under 1%; so, they are only slightly higher than the difference of the measurement values of different authors.
