R407A

 

R407A (also known as Forane R407A and Freon R407A) is a zeotropic mixture consisting of 20 weight % R32, 40% R125 and40% R134a.   It is considered to be a replacement fluid for R2.  It has a molar mass of 90.11 kg/kmol.

 

Property data for R07A are provided using a generalized equation of state fitted by F-Chart Software using thermodynamic property data from the manufacturer and generated by REFPROP.  The model is applicable for temperatures between 170 K and 450 K with pressures up to 50 MPa.  The reference state is saturated liquid at 0C for which specific enthalpy and entropy are 200 kJ/kg and 1.0 kJ/kg-K, respectively.  

 

Transport properties are derived from information provided by REFPROP.
