Thermodynamic Properties of DuPont™ Freon® 12 (R12)SI Units

Tables of the thermodynamic properties of DuPont™ Freon®

12 (R-12) have been developed and are presented here. This

information is based on values calculated using the NIST

REFPROP Database (McLinden, M.O., Klein, S.A., Lemmon,

E.W., and Peskin, A.P., NIST Standard Reference Database

23, NIST thermodynamic and transport properties of refriger-

ants and refrigerant mixtures – REFPROP version 6.01, Stan-

dard Reference Data Program, National Institute of Standards

and Technology, 1998).
