Definitions

  • the invention the object of which is to eliminate the above mentioned drawbacks relates to an arrangement for an adjustable Ventilation in tunnels or similar spaces divided in the above mentioned manner into a number of sections each connected to a Ventilating duct provided with a separate fan. It is new and characteristic for the invention that the Ventilating ducts are so arranged that each duct along one part of its length has two side walls in common with the other duc-ts and that in these partitioning walls there are arranged openings equipped with governing dampers.
  • FIG. l shows schematically a vertical section through a traflic tunnel with a Ventilating arrangement according to the invention and
  • FIG. 2 shows a horizontal section through the ventilating ducts along the line lI-Il in FIG. 1.
  • FIG. 1 designates a traffic tunnel which in the case shown with respect to the Ventilation is divided into three sections A, B and C.
  • a Ventilating duct is arranged for each section, which ducts in the drawing are designated 2, 3 and 4 respectively. All the Ventilating ducts are connected to separate fan aggregates 5, 6 and 7 respectively.
  • said 2,996,973 Patented Aug. 22, 1961 ICC Ventilating ducts are so arranged that each duct has two side walls in common with the other ducts as is shown more clear in FIG. 2. Furthermore, openings 9, 12 and 15 provided with regulating dampers 8, 12 and 16 respectively are arranged in these common side walls, which in the drawing are designated 10, 11 and 14.
  • the amount of Ventilating air for the sections can be regulated in the proportions l, 2/3 and 16 by using three, two and one fan respectively. lf, for instance the dampers 8 and 13 are closed but the damper 16 is open and the fan 7 for the Ventilating duct 4 is shut oi, a maximum of Ventilation of the section A will be obtained while the quantity of Ventilating air will be reduced to a half for the sections B and C etc.
  • the position and shape of the ducts as well as the number of the sections ican can of course be Varied in dilerent manners without departing from the idea of the invention.
  • Adjustable Ventilating means for tunnels and the like which are divided into at least two sections, compiising a separate Ventilating duct for each section, each of said ducts terminating in its respective tunnel section, said ducts being disposed adjacent each other and having a common side wall, an opening in said common side wall, dampers for said opening selectively operable in two positions to respectively open and close said opening, and a separate fan in each duct at the side of said opening remote from said tunnel sections and selectively operable between operative and inoperative conditions, whereby the Ventilation in each tunnel section may be regulated stepwise by operation of said dampers and selective operation of said fans.
  • Adjustable Ventilating means for tunnels and the like which are divided into at least three sections, comprising a separate Ventilating duct for each section, each of said ducts being disposed adjacent two other ducts and having common side walls, therewith, an opening in each common side wall, dampers for each of said openings selectively operable in two positions to respectively open and fclose said opening, and a separate fan in each duct at the side of said opening remote from said tunnel sections and selectively operable between operative and inoperative conditions, whereby the ventilation in each tunnel section may be regulated stepwise by operation of said dampers and selective operation of said fans.
