R1234yf

 

R1234yf provides thermodynamic and transport property data for HFO-1234yf (2,3,3,3-tetrafluoropropene, MW 114.04116 g/gmole).  The thermodynamic properties are based on the information provided in

 

Markus Richter, Mark O. McLinden, and Eric W. Lemmon

"Thermodynamic Properties of 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf): Vapor Pressure and p-rho-T Measurements and an Equation of State"

Journal of Chemical and Engineering Data, 2011, 56, 3254-3264

 

The equation of state is valid for temperatures ranging from 220 K to 410 K at pressures up to 30 MPa.  Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K respectively for saturated liquid at 273.15 K. 

 

Viscosity

Viscosity is determined using the information from:

Huber, M.L., and Assael, M.J.,

"Correlations for the viscosity of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E))"

Int. J. of Refrigeration, Vol 21, pp. 39-45, (2016)

 

Thermal Conductivity

Thermal Conductivity is obtained from the correlation provided by:

Perkins, R.A. and Huber, M.L, "Measurement and Correlation of the Thermal Conductivity of 2,3,3,3-Tetrafluorprop-1-end (R1234yf) and trans-1,3,3,3-Tetrafluoropropene (R1234ze(E))
