Abstract
Improvements in the condensing heat transfer surface of a condenser which handles organic working fluids whose surface tension is not more than 35 dyne/cm as gas mediums to be condensed. The improvements comprise the formation of a plurality of transversely spaced vertically extending grooves on the condensing heat transfer surface on which the gas medium condenses. The pitch of the grooves is about 1-2 mm and the depth is about 0.3-0.6 mm.
