Research heat- and mass exchange at condensation pair of ammonia vapor from air and ammonia mix on spiral wire finned bundles of horizontal tubes

摘要

The results of research heat-and mass exchange are given at condensation of ammonia's vapour at the presence of air on smooth and with optimum parameters wire finned tubes. The offered accounting dependences allowed to carry out heat prediction of tube bundles of ammoniac condensers with smooth and spiral-wire finned tubes in a range of air concentrations of air from 0 to 30 %.
