Summary

Based on the pressure-volume-temperature data published in recent years a new virial equation of state for R134a is presented. This equation was fitted by the way of Least-Square Fitting and DSFD. The accuracy of this equation to calculate the termodynamic properties such as pressure-volume-temperature, isobaric specific heat capacity, constant-volume specific heat capacity and sound velocity are also presented and compared with that of Piao's equation. The results show that this equation is applicable in wider thermodynamic region with good accuracy.
