R444A
R444A (also known as Koura R-444A) is a zeotropic mixture consisting of 83 weight% R1234ze(E),12 R32, and 5% R152A. It is considered to be a replacement fluid for R1234ze(E). It has a molar mass of 96.7 kg/kmol.
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.
