چکیده انگلیسی
A new analytical equation of state is examined for a number of compressed liquid HCFC and HFC refrigerants. The equation is that of Ihm et al. in which the three temperature dependant parameters, second virial coefficient, van der Waals co-volume, and the correcting parameter for the softness of potential energy, are calculated by means of the corresponding states correlations developed by Papari et al. The required scaling constants are the heat of vaporization and the density at boiling point, ÎHvap and Ïnb, respectively. The EoS is applied to these liquid refrigerants to calculate the density at a good range of temperatures lower than their critical points. The results are fairly consistent with the experiment, at most within ±5%.
