R515B (also known as Honeywell Solstice N1) is an azeotropic mixture consisting of 91.1 weight% R1234ZE and 8.9% R227EA that is considered to be a replacement fluid for R134a. It has a molar mass of 119.0 kg/kmol.
Property data for R515B 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 170 K and 420 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.
Transport property data are assumed to be the same as for
