(EN) AIRCRAFT FUEL TANK VENTILATION HAVING A DEHUMIDIFYING DEVICE
(FR) VENTILATION DE RÉSERVOIR DE CARBURANT D AVION COMPORTANT UN DISPOSITIF DE DÉSHUMIDIFICATION
Abstract
(EN)
An aircraft fuel tank ventilation system, comprising a refrigerative dehumidifying device (17) having a refrigerating element (21) in contact with air flowing between a vent (15) open to the atmosphere and a fuel tank (4, 5). Also, a method of dehumidifying air introduced into an aircraft fuel tank via the ventilation system, the method comprising directing atmospheric air from the vent into contact with the refrigerating element, and cooling the refrigerating element so as to remove water vapour from the air flowing from the vent towards the fuel tank by condensation.

(FR)
La présente invention se rapporte à un système de ventilation de réservoir de carburant d'avion, comprenant un dispositif de déshumidification à réfrigération (17) comportant un élément de réfrigération (21) en contact avec l'air circulant entre un orifice (15) s'ouvrant sur l'atmosphère et un réservoir de carburant (4, 5). De plus, l'invention se rapporte à un procédé consistant à déshumidifier l'air introduit dans un réservoir de carburant d'avion par l'intermédiaire du système de ventilation, le procédé comprenant l'orientation de l'air atmosphérique provenant de l'orifice en contact avec l'élément de réfrigération, et le refroidissement de l'élément de réfrigération de manière à retirer la vapeur d'eau de l'air circulant de l'orifice vers le réservoir de carburant par condensation.
