Thermal Conductivity Measurements for the Hydrochloroolefin R1130(E)

The identification of new refrigerants characterized by low GWP (< 150), as required at international level by several agreements and regulations, is still far from the conclusion. In particular, for a proper selection, the thermophysical properties of hydro(chloro) fluoroolefins (H(C)FOs) are required, but their knowledge is still scarce for several of these fluids. Amongst these, R1130(E) has recently get some attention as a component, with R1336mzz(Z), of the azeotropic binary mixture (R514A), that could be applied as a substitute for R123 in centrifugal chillers, high-temperature heat pumps, and organic Rankine cycles. R1130(E) is a hydrochloroolefin characterized by a relatively high normal boiling temperature (320.9 K) and belongs to the ASHRAE safety group B1. Its properties are still not widely studied and, in particular, a very limited number of data is available in the peer reviewed literature for the thermal conductivity. Thus, in this paper, a set of experimental thermal conductivity data, performed with a double THW apparatus, will be presented. The data are measured in the range of temperatures between 243.15 and 313.15 K, with pressures up to 8 MPa.
