文摘The liquid molar volumes of nonazeotropic refrigerant mixtures(NARM), calculated with Peng Robinson (PR) equation, were compared with vapor-liquid equilibrium experimental data in this paper.Provided with coreaction coefficient kij, the discrepancies of liquid molar volume data for R22+R142b and R22+R142b using PR equation are 7.7% and 8.1%, respectively. When HBT (Hankinson-Brobst-Tholnson) equation was joined with PR equation, the deviations are reduced to less than 1.5% for both R22+R114 and R22+R142b.
