R422D (also known as ISCEON® MO29 and Genetron 422D) is a zeotropic mixture consisting of 31.5 weight% R134a, 65.1% R125 and 3.4% Isobutane. It is considered to be a replacement fluid for R22. It has a molar mass of 109.9 kg/kmol.
Property data for463A 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 200 K and 480 K with pressures up to 20 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. Viscosity, thermal conductivity and surface tension data were fit to data obtained from REFPROP.
