ShareEffect of fin geometry on condensation of downward-flowing R123/R134a in a staggered bundle of horizontal low-finned tubes.
Author(s) : HONDA H., TAKAMATSU H., TAKATA N.
Summary
Experiments were conducted to obtain row-by-row heat and mass transfer data during condensation of downward-flowing zeotropic mixture R123/R134a in a staggered bundle of horizontal low-finned tubes. The vapour temperature and the mass fraction of R134a at the tube bundle inlet were about 50°C and 14% respectively. The refrigerant mass velocity ranged from 9 to 33 kg/m2 second, and the condensation temperature difference from 2 to 10 deg K. Four kinds of low-finned tubes with differences in geometry were tested.
