R466A (also known as Honeywell Solstice N41) is a mixture consisting of 49 weight% R32, 11.5% R125 and 39.5% R13I1 It has a molar mass of 80.7 kg/kmol. R466A is considered to be a replacement for refrigerant R410A. . It has been modeled as a pseudo-pure fluid based in the manner described by:
"Pseudo-Pure Fluid Equations of State for the Refrigerant Blends R-410A, R-404A,R-507A, and R-407C"
International Journal of Thermophysics, Vol. 24, No. 4, July 2003
The model provided by EES was generated by fitting mixture data from the REFPROP program to a fundamental equation of state with separate correlations for the bubble and dew point pressures. The model is applicable for temperatures between 170 K and 420 K with pressures up to 50 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 data from the manufacturer and a corresponding states approach as suggested in:
