Resumo: | Thermodynamic property data including specific enthalpy, specific entropy and specific volume were generated for the new refrigerant HFO-1234yf (2,3,3,3-tetrafluoroprop-1-ene) using the well-known Peng and Robinson cubic equation of state. A general approach applicable to any fluid based on the concept of departure functions has been applied. Data for saturated vapor pressure, saturated liquid density, ideal gas heat capacity at constant pressure and critical properties were obtained from the open literature. The predictive capability of the proposed calculation methodology has been validated with thermodynamic property data for HFC-134a (1,1,1,2-tetrafluoroethane), showing average deviations lower than 0.6%. A thermodynamic analysis of the new refrigerant in the light of thermodynamic properties of an idealized cycle was carried out so as to measure its performance with respect to that HFC-134a under the same evaporating and condensing pressure conditions. |
