Definitions
- the invention relates to a jet fan, in particular an axial fan for the ventilation of Tunneling, with at least one in a fan shaft arranged fan and at least one Nozzle arrangement on the inlet and / or outlet side the fan shaft attached and preferably with is provided with a silencer.
- jet fans are used in particular for loading and End ventilation of road tunnels used.
- the fan creates one in the fan shaft strong air flow through the nozzle assemblies to the Flow conditions in the tunnel is adjusted.
- the nozzle assemblies combined with silencers to to reduce the fan noise.
- the air flow in the tunnel is particularly close to the wall slowed down by friction of the air on the walls.
- the highest flow rate can therefore in the Reach tunnel means. From a fluidic point of view therefore the middle of the tunnel is the ideal place for installation of the jet fan.
- the Jet fan not in the area through the tunnel moving vehicles can be arranged. Therefore the Jet fan near the tunnel wall or the tunnel ceiling.
- the fan output becomes less and less in one effective air flow through the entire tunnel implemented, the closer the fan is to the wall is arranged. That means: the closer a jet fan is to the Wall or ceiling is mounted, the worse it will be Efficiency.
- the object of the invention is to provide a jet fan for to specify the ventilation of tunnels, despite the arrangement higher efficiency near the tunnel wall with respect to the air flow generated in the tunnel.
- the solution to this problem according to the invention provides that an air duct of the respective nozzle arrangement is inclined with respect to the fan shaft, so that the inflow and outflow direction opposite the Flow direction of the fan shaft one Has angle.
- the jet fan according to the invention can now in the Near the tunnel wall or ceiling so that the inflow and outflow directions away from the tunnel walls point. This will make it easier in the middle of the tunnel flowing air from the nozzle assembly on Fan inlet sucked in the fan shaft accelerated and by the nozzle arrangement on Fan outlet again diagonally towards the center of the tunnel blown out.
- the effect of Reduced wall friction on the air flow and the Effectiveness of the jet fan increased considerably.
- the invention produces Jet fan compared to conventional Jet fans of the same fan power one Flow velocity in the tunnel, the one Thrust increase by approx. 35% corresponds.
- the suspension of the jet fan will be the best Results achieved when the angle of the input and / or Outflow direction compared to the flow direction of the fan shaft in the range between 3 degrees and 25 degrees.
- the jet fan according to the invention is the inclination generated by transition pieces between the Fan shaft and the nozzle arrangements arranged are.
- these transition pieces exist from a short piece of pipe with flanges to both Pages, which according to the desired inclination in Angles are arranged to each other.
- This has the advantage that conventional nozzle arrangements and fan shafts can be adopted unchanged. Instead of that Nozzle arrangements directly with a fan shaft connect them to both sides of the Transition pieces attached.
- This embodiment is suitable also installed for retrofitting Jet fans, their effectiveness thus retrospectively can be increased.
- Another embodiment variant provides that a Nozzle arrangement inside with an oblique air duct Is provided. This measure is recommended if the outer shape of the nozzle assemblies from aesthetic or should be straight for installation reasons.
- Jet fan in the transition area between the arranged side tunnel walls and the tunnel ceiling the level defined in this way runs at the left arranged jet fan from top left to right below or with the jet fan from top right to bottom left diagonally through the Cross-section of the tunnel and thus through the center of the tunnel.
- the jet fan 1 shown in FIG. 1 is by means of a bracket 2 on the tunnel ceiling 3 one Road tunnels attached. It consists of one Fan shaft 4, in which a fan 5 is arranged is, two nozzle arrangements 6, 7 and two between the respective nozzle arrangements 6, 7 and the inputs and Outlet sides 8, 9 of the fan shaft 4 arranged Transition pieces 10, 11.
- the transition pieces 10, 11 consist of short pieces of pipe that end at their ends Flanges 12, 13 are provided.
- the two flanges 12, 13 of a transition piece 10, 11 are at an angle of 3 ° to 25 degrees to each other.
- the jet fan 1 shown in FIG. 2 differs from that shown in Figure 1 only by modified nozzle arrangements 18, 19, the side facing the fan shaft 4 20 are bevelled.
- the invention Inclination of the nozzle arrangements 18, 19 relative to that Fan shaft 4 results in this Embodiment by directly connecting the respective beveled side 20 with the straight inlet 8 or Outlet side 9 of the fan shaft 4, without Interposition of a transition piece.
