Klymchuk O. Increasing the efficiency of transpiration cooling at industrial power systems

The object is represented with evaporator condensator; the goal being considered as creating compact heat-mass exchange units for media evaporative cooling; heat mass exchange processes studies effected both theoretically and experimentally with test samples' trials under full-scale experiment. The novelty consists in indirect evaporation coolers main kinds developing, as well as their internal processes mathematical models with regard to non-equity of fluid surfacial film distribution over heat-mass exchange area; the results obtained demonstrate the optimal number of such coolers for multisection units set as not exceeding three ones, the optimal scheme (as to heat and energy indexes) for complex evaporation cooler then would consist of indirect evaporation cooler and direct evaporation cooler. As to the practical application several technical grounds for industrial purpose heat-mass exchange units' new generation are developed; area of application being cooling both air and water for industrial anddomestic purposes.
