Measurement of thermal conductivity and correlations at saturated state of refrigerant trans-1‑chloro‑3,3,3-trifluoropropene (R-1233zd(E)).

In this work, thermal conductivity of a refrigerant trans -1‑chloro‑3,3,3-trifluoropropene (R-1233zd(E)) was measured and simplified correlations at saturated state were proposed. R-1233zd(E) is an unsaturated hydrochlorofluoroolefin and it is considered as an alternative working fluid due to its preferable properties. The thermal conductivity of R-1233zd(E) was measured by a well-established transient hot-wire method at temperatures from 313 to 433 K and 334 to 474 K for the liquid and vapor phases, respectively for pressures up to 4.0 MPa. Experimental values of thermal conductivity were compared to predicted values from conventional correlations as well as proposed simplified correlations for saturation condition. The estimated combined standard uncertainty of thermal conductivity of R-1233zd(E) was found ± 2.17% for liquid and ± 2.52% for vapor at a confidence level of 95%. [ABSTRACT FROM AUTHOR]
