Abstract

The volume of saturated vapor and saturated liquid of R134a were calculated by using four cubic equations of state: SRK,PR ,T-L and S-Y . Calculation shows that in the range of ? 50 ? 90 ? ,the T-L equation of state has the highest calculating accuracy, the average deviations of calculation of saturated vapor volume and saturated liquid volume being1.63% and 4.12% respectively. Those of PR equation are 1. 90% and 4.76%, while the average deviations of calculation of SRK equation are 3.35%and 18. 64% respectively, the largest of the four equations of state for either saturated vapor or saturated liquid. S-Y equation has equal accuracy of calculation with PR equation, the average deviations being 2. 00% for saturated vapor and 5. 21% for saturated liquid. T-L equation of state is recommended to calculate thermodynamic properties of R34a for engineering purposes.
