The present invention relates to a device (1) in a ventilation system, which comprises a supply duct (3) and an air-discharge duct (4), which lead into at least one air-passage opening (5, 6, 7) connected to the environment (8). The invention makes it possible, inter alia, to reduce the risk of an admixture of so-called "old" air with so-called "new" fresh air in a ventilation system. The supply duct (3) comprises two diametrically opposite air-supply openings (5, 6), and an air-discharge opening (7) is situated on a level separate from the two supply openings (5, 6) mentioned, at least one part (3A) of the supply duct (3) mentioned extending between the two supply openings (5, 6) mentioned. <IMAGE> |
