Summary

This study experimentally investigated the boiling/condensation heat transfer and pressure drop characteristics of HFO1336mzz(E) and a mixture of HFO1336mzz(E) and HFO1336mzz(Z), inside a horizontal microfin tube. The test tube was copper, with an outside diameter of 9.52 mm, an equivalent inner diameter of 8.95 mm, fin heights of 0.12 mm, a helix angle of 16.5°, and 65 fins. The experiments were conducted under a mass velocity range from 50 to 300 kgm-2s-1 at boiling and condensation saturated temperatures of 40 °C and 60 °C. The relationship between heat transfer coefficient/frictional pressure drop and vapor quality in boiling and condensation processes were clarified. The boiling/condensation heat transfer coefficient of HFO1336mzz(E) was lower than that of R245fa, however the pressure drop of HFO1336mzz(E) was lower than that of R245fa.
