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).
