Air-handling device

Abstract

A method for handling air when distributing air inside an elongated vehicle includes supplying air to a roof air duct ( 15 ) inside the vehicle. A device for handling air when distributing air inside an elongated vehicle is also disclosed. It is significant of the method according to the present invention that in connection with the supply of air to the roof air duct ( 15 ) the air is actively directed in at least one chosen direction.

       5 . Device according to  claim 4 , characterised in that the vanes ( 12 ) are parallel. 
   
   
       6 . Device according to  claim 4 , characterised in that the vanes ( 12 ) are adjustable as regards their turning/tilting. 
   
   
       7 . Device according to  claim 6 , characterised in that the adjustment of the vanes ( 12 ) is carried out manually. 
   
   
       8 . Device according to  claim 4 , characterised in that the vanes ( 12 ) are included in a vane unit ( 9 ) that comprises a frame ( 11 ), the vanes ( 12 ) being hingedly connected to the frame ( 11 ). 
   
   
       9 . Device according to  claim 3 , characterised in that a diffuser ( 8 ) is provided between the air moving means ( 7 ) and the means ( 9 ) for actively directing the air. 
   
   
       10 . Device according to  claim 5 , characterised in that the vanes ( 12 ) are adjustable as regards their turning/tilting. 
   
   
       11 . Device according to  claim 10 , characterised in that the adjustment of the vanes ( 12 ) is carried out manually.
