R515B

 

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 0C 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 R515A
