Abstract

<p>The surface tension was measured for several low GWP refrigerants, which are grouped in HCFO and HFO, by a differential capillary rise method. The comparison between measured data and calculated value by REFPROP 10.0 were reviewed. The review results suggest that the uncertainty in surface tension calculated by REFROP 10.0 are not negligibly small for R1224yd(Z) and R1336mzz(Z). Based on the measured data and calculated orthobaric densities, "Parachor" was identified for each refrigerant. Among the measured refrigerants, the parachor of only R1336mzz(E) showed obvious temperature dependence, which means there could be an inconsistency between orthobaric densities and surface tension.</p>
