Résumé

This paper presents a timely and reliable equation of state for 2,3,3,3-tetrafluoropropene (HFO-1234yf) whose thermodynamic property information is strongly desired. The Patel-Teja (PT) equation of state and the extended corresponding state (ECS) model have been individually applied to property modelling for this new refrigerant. Comparisons of predicted values with the equation/model were made with the most recent experimental data. Both the PT equation of state and the ECS model can represent the vapour pressures with an accuracy of 0.2%. However, the ECS model is much better than the PT equation of state in the predictions for the liquid density and isobaric heat capacity. The uncertainties of calculated values with the ECS model are 0.5% in liquid density and 2.5% in isobaric heat capacity. The use of the ECS model is recommended for a detailed assessment of HFO-1234yf. Thermodynamic property tables and diagrams generated using the ECS model are provided.
