RE245cb2 provides thermodynamic and transport property information for refrigerant RE245cb2, also known as C3H3F5O, HFE245mc, methyl-pentafluoroethyl-ether, and pentafluoroethyl methyl ether with CAS#22410-44-2).  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 20 MPa.  


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


Transport property information (except for gaseous viscosity) are from:

The viscosity of RE245cb2 in the gas phase is estimated using a corresponding states approach (with R365mfc as the reference fluid) as suggested in:
