A ventilating device (1) comprises one or more impellers (2) extending in a longitudinal direction around an axis of rotation. Each of the impellers (2) is adapted to suck air from an ambient atmosphere in a transverse direction over a substantial part of the impeller's length. A coupling for transmitting a driving force from one impeller to another is disclosed. The ventilating device may be comprised in a unit with a cover (6) and a chassis, and it may be mounted to or around a heating or cooling pipe (3; 4) in a room of a building. A holding member (5) which may be connected to the cover (6) holds the pipe or pipes (3; 4) and/or one or more impellers (2). The device is easy to mount and may have improved energy efficiency. A building with a ventilating device, a method of operating the ventilating device, a system comprising a plurality of ventilating devices, and a mounting member for one or more pipes and/or one or more impellers are further provided.

L'invention concerne un dispositif de ventilation (1) comportant une ou plusieurs turbines (2) s'étendant dans le sens longitudinal autour d'un axe de rotation. Chaque turbine (2) peut extraire de l'air provenant de l'atmosphère environnante de manière perpendiculaire sur une grande partie de la longueur de la turbine. L'invention concerne également un coupleur destiné à transmettre une force d'entraînement d'une turbine à l'autre. Le dispositif de ventilation selon l'invention peut être logé dans une unité comportant un capot (6) et un châssis, et peut être monté sur ou à proximité d'un conduit de chauffage ou de climatisation (3, 4) d'un bâtiment. Un élément de fixation (5) pouvant être relié au capot (6) retient le ou les conduits (3, 4) et/ou une ou plusieurs turbines (2). Ledit dispositif est simple à monter et peut présenter un rendement énergétique amélioré. L'invention concerne par ailleurs un bâtiment comportant ledit dispositif de ventilation, un procédé d'utilisation dudit dispositif de ventilation, un système comportant une pluralité de ces dispositifs de ventilation, et un élément de montage destiné à un ou plusieurs conduits et/ou une ou plusieurs turbines.
