R465A
R465A is a zeotropic mixture consisting of 21 weight% R32, 7.9% propane and 71.1% R1234yf. It is considered to be a replacement fluid for R404A and R22. It has a molar mass of 82.9 kg/kmol and a GWP of 143. It is flammable and considered to be an A2L refrigerant.
Property data are provided using a generalized equation of state fitted by F-Chart Software using thermodynamic property data generated by REFPROP. The model is applicable for temperatures between 180 K and 420 K with pressures up to 10 MPa. The reference state is saturated liquid at 0 C for which specific enthalpy and entropy are 200 kJ/kg and 1.0 kJ/kg-K, respectively.
Transport properties are estimated using a corresponding states approach as suggested in:
