Abstract

La présente invention concerne un procédé et un appareil permettant d'effectuer un refroidissement indirect amélioré par évaporation d'air, d'eau, de combustible ou d'autres fluides, tout en régulant l'humidité. Cette conception permet un refroidissement jusqu'au point de rosée sans entrée d'énergie en plus de l'énergie nécessaire pour produire l'écoulement de fluide voulu. On utilise des plaques composites empilées (7) pourvues de voies pour l'écoulement fluidique entre les plaques adjacentes. Sur les surfaces opposées de ces plaques, on trouve des zones humides (4) ou des zones sèches (3). Les zones humides (4) permettent un refroidissement par évaporation classique utilisé également pour refroidir les fluides en contact avec les zones sèches (3). L'avantage de cette invention est le transfert thermique contrôlé qui permet un refroidissement sélectionné d'écoulement fluidique de manière à atteindre des températures aussi basses que le point de rosée.
