Thermodynamic Properties of R134a (1,1,1,2-tetrafluoroethane)
The thermodynamic surlace of R134a is expressed in terms of a 32-term modified Benedict· Webb-Rubin (MBWR) equation of state. Coefficients for this equation and for the ancillary equations representing the saturated liquid and vapor densities and the vapor pressure are presented. Temperatures are given on the new International Temperature Scale· of 1990 (lTS 90). The MBWR coefficients were obta...
متن کاملA Thermodynamic Property Model for the R-134a/245fa Mixture
A thermodynamic property model explicit in the Helmholtz energy is presented for the R-134a/245fa mixtures. A multi-fluid approximation based on pure-fluid Helmholtz energy equations of state forms the basis of the property model. The Helmholtz energy of the mixture is expressed as the sum of the ideal gas contribution, the compressibility contribution (real fluid contribution), and the contrib...
