RE245fa2 provides thermodynamic and transport property information for refrigerant RE245fa2 (2,2,2-trifluoroethyl-difluoromethyl-ether, CAS# 1885-48-9).  The thermodynamic properties are determined from the equation of state in:

The correlation is valid for temperatures in the range between 250 K to 500 K for pressures less than 400 MPa.  


Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K, respectively, for saturated liquid at 0 C. 


Transport property information (except for gaseous viscosity) are from a corresponding states approach as described in:
