.ThermofluidStream.Media.XRGMedia.R1234yf_ph.dt_ph

Information

This function calculates the density and temperature of R1234yf from absolute pressure and specific enthalpy. In one-phase region the function calls the fundamental helmholtz equation of Richter et al (2011). In two-phase the density and temperature is computed from cubic splines for saturated pressure, liquid and vapor density.
