A. Laesecke et al., AN IMPROVED CORRELATION FOR THE THERMAL-CONDUCTIVITY OF HCFC123 (2,2-DICHLORO-1,1,1-TRIFLUOROETHANE), International journal of refrigeration, 19(4), 1996, pp. 231-238
An updated survey of the existing thermal conductivity data for HCFC12
3 is presented. In addition, new wide-ranging thermal conductivity mea
surements, which have been carried out at NIST, are summarized. These
results supplement the existing database and are used for an improved
correlation of the thermal conductivity of HCFC123. The correlation co
vers the temperature range from 180 to 480 K with pressures up to 67 M
Pa or densities up to 1900 kg m(-3). The correlation includes an empir
ical critical enhancement term of a form suitable for industrial use a
nd represents the NIST dataset within +/- 2.22% at the 95% confidence
level.
