Abstract
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.
