  • coolers can freeze (without the cooler being in operation, ie through which process water flows) if the air entering the cooler is at around 0 ° C with high humidity, which means that the operation of an entire system, for example a gas turbine system, is not possible under certain air conditions, ie the cooler has to be at least partially dismantled to prevent this, or an air heater must be connected upstream of the cooler, which causes additional investment and operating costs, which are relatively high.
  • evaporative coolers which are neither movable in themselves nor as a whole and cause a constant pressure loss, which has a corresponding negative effect (e.g. efficiency and / or loss of performance) on upstream or downstream systems.

Abstract

L'invention concerne un refroidisseur par évaporation à monter dans des installations fixes ou mobiles, notamment dans des conduits d'air d'aspiration de centrales à turbine à gaz. Ce refroidisseur par évaporation (20) comprend une partie supérieure (2), une partie corps de contact (5) située sous la partie supérieure, et une partie cuve (3) disposée sous la partie corps de contact (5). L'invention est caractérisée en ce que ledit refroidisseur (20) est équipé de dispositifs de pivotement, qui permettent de faire pivoter l'appareil (20) ou une partie de celui-ci de sa position de fonctionnement (transversale au flux d'air) en une position oblique relativement au flux d'air. Le refroidisseur a ainsi une résistance à l'écoulement de l'air réduite lorsqu'il n'est pas en position de fonctionnement.
