Provided is an assembly for insulating substantially vertical runs of cooled surfaces (12) that are continuously or periodically exposed to air or another gas that has a dewpoint temperature above that of the cooled surface, thereby resulting in condensation water vapor on or adjacent the cooled surface. One embodiment of the insulating assembly provides a wicking material layer (14) adjacent the cooled surface that, in combination with transporting and evaporating structures, removes the condensate from the vicinity of the cooled surface and allows for its evaporation into the ambient gas surrounding the exterior surface of the insulating assembly. Another embodiment provides for exposing the condensate to an internal conditioned gas stream to provide for evaporation that does not necessarily utilize an exterior surface. Both embodiments remove condensate from the insulating structure and thereby tend to avoid any substantial condensate accumulation and maintain the insulating performance.
L'invention concerne un ensemble permettant d'isoler des parties sensiblement verticales de surfaces refroidies (12) qui sont continuellement ou périodiquement exposées à l'air ou à un autre gaz dont la température de point de rosée est supérieure à celle de la surface refroidie, ce qui produit de la vapeur d'eau de condensation sur ladite surface refroidie ou adjacente à celle-ci. Dans un mode de réalisation, l'ensemble d'isolation comprend une couche de matériau (14) à effet de mèche adjacente à la surface refroidie qui, combinée à des structures de transport et d'évaporation, permet d'éliminer le condensat à proximité de la surface refroidie et permet son évaporation dans le gaz ambiant entourant la surface extérieure de l'ensemble d'isolation. Dans un autre mode de réalisation, le condensat est exposé à un flux gazeux interne conditionné pour être évaporé, ce qui ne requière pas l'utilisation d'une surface extérieure. Les deux modes de réalisation permettent d'éliminer le condensat de la structure d'isolation, ce qui empêche l'accumulation sensible de condensat et permet de maintenir la performance d'insolation.
