ShareSummary
The vapour pressure of R134a has been measured for the temperature range from 279.15 to 363.15 K. The measured vapour pressure data and data reported by other investigators have been evaluated, and a vapour pressure data set with reasonable accuracy has been obtained. Based on this consistent and reliable data set, a Wagner type equation has been determined. This equation contains four coefficients and correlates the measured vapour pressures with high accuracy (0.05350%).
