Properties of Refrigerants

Values calculated from NIST Thermodynamic Properties of Refrigerants and Refrigerant Mixtures Database (REFPROP, Version 5). Thermodynamic properties are from. 32-term MBWR equation of state transport properties are from extended corresponding states model, t = triple point c = critical point. 

Data from ASHRAE Thermodynamic Properties of Refrigerants (Stewart etal. 1986) or from McLinden (1990), unless otherwise noted.

The 1993 ASHRAE Handbook—Fundamentfds (SI ed.) contains a table at closer temperature increments and also an enthalpy-log-pressure diagram from 0.1 to 35 bar,-80 to 220 °C. Eor tables and a chart to 500 psia, 480 F, see Stewart, R. B., R. T. Jacobsen, et s., Thermodynamic FroperUes of Refrigerants, ASHRAE, Atlanta, GA, 1986 (521 pp.). Eor specific heat, thermal conductivity, and viscosity, see Thermophysical Properties of Refrigerants, ASHRAE, 1993. 

The values in these tables were generated from the NIST REFPROP software (Lemmon, E. W., McLinden, M. O., and Huber, M. L., NIST Standard Reference Database 23 Reference Fluid Thermodynamic and Transport Properties—REFPROP, National Institute of Standards and Technology, Standard Reference Data Program, Gaithersburg, Md., 2002, Version 7.1). The primary source for the thennody-namic properties is Platzer, B., Polt, A., and Maurer, G., Thermophysical Properties of Refrigerants, Springer-Verlag, Berlin, 1990. Validated equations for the viscosity and thermal conductivity are not currently available for this fluid.
