Definitions
- the invention relates to a jet fan, in particular a Axial fan for ventilation of tunnels, with at least one in a fan shaft arranged fan and one each Nozzle assembly located at the inlet and outlet sides of the Fan shaft attached and provided with a silencer.
- Such jet fans are used in particular for ventilation used by road tunnels.
- the fan generates in Fan duct a strong airflow passing through the Nozzle arrangements adapted to the flow conditions in the tunnel becomes.
- the nozzle assemblies are combined with silencers to to reduce the noise development of the fan.
- the air flow in the tunnel is particularly through near the wall Friction of the air at the walls braked.
- the highest Flow rate can therefore be achieved in the tunnel means. From a fluidic point of view, therefore, the tunnel center would be the ideal location for installation of the jet fan.
- the Jet fan not in the area of the tunnel Vehicles be arranged. Therefore, the jet fan must be nearby the tunnel wall or the tunnel ceiling are mounted. But the fan power is less and less in an effective Air flow through the entire tunnel is implemented, the closer the Fan is arranged on the wall. That is: the closer a jet fan the wall or ceiling is mounted, the worse is its efficiency.
- From DE-A-25 09 279 is a ventilation device for Road cover known, which is supported by shoring. Because of the strong air resistance generated by the shoring in Road direction is provided a transverse ventilation.
- the Ventilation device therefore consists of a wall of the Road cover penetrating air duct and a fan, which conveys the air from outside into the interior. This is it not a jet fan, the air in the interior in Lane direction blows. The problem of air resistance in Road direction is rather bypassed by the transverse ventilation.
- the object of the invention is to provide a jet fan for the ventilation of Specify tunneling, despite the arrangement near the tunnel wall a higher efficiency with respect to the tunnel generated Has air flow.
- the achievement of this task according to the invention provides that the Silencer with nozzle existing nozzle arrangements over the Fan shaft are arranged inclined, so that the input and Outflow direction relative to the flow direction of Fan shaft has an angle.
- the jet fan according to the invention can now close to the Tunnel wall or ceiling are mounted so that the inputs and Outflow directions point away from the tunnel walls.
- the in the tunnel center easier flowing air from the nozzle assembly on Suction fan inlet, accelerated in the fan shaft and through the nozzle assembly at the fan outlet again obliquely in the direction Tunnel center blown out.
- the effect of the Wall friction on the air flow decreases and the effectiveness of the Jet fan significantly increased.
- the Jet fan according to the invention compared with conventional Jet fans the same fan power one Flow velocity in the tunnel, which increases by about 35% corresponds.
- the Best results are achieved when the Angle of the inlet and / or outflow direction relative to the Flow direction of the fan shaft in the range between 3 Degrees and 25 degrees.
- Jet fan the inclination is generated by transition pieces, the between the Fan shaft and arranged the nozzle assemblies are.
- these transition pieces from a short piece of pipe with flanges to both Pages which correspond to the desired inclination in the Are arranged angle to each other.
- This has the advantage that conventional nozzle arrangements and fan shafts can be taken over unchanged. Instead of the Nozzle arrangements directly with a fan duct connect, they will be on both sides of the Attached transition pieces.
- This embodiment is suitable also for retrofitting already installed Jet fan, their effectiveness thus subsequently can be increased.
- one facing the fan shaft for connection with the inlet and outlet side of the fan shaft beveled certain side of a nozzle assembly is trained.
- This variant is needed no transition pieces and therefore only requires one lower production costs. But she is to Retrofit already installed jet fans because of the special shape of the nozzle arrangements only provided that the Nozzle arrangements are completely replaced.
- a further embodiment variant provides that a Nozzle arrangement inside with an oblique air duct Is provided. This measure is recommended when the outer shape of the nozzle arrangements of aesthetic or installation-technical reasons should be straight.
- the Flow direction of the fan shaft and the Inlet and / or outflow direction of the nozzle arrangements in essentially arranged lying in one plane, wherein the jet fan can be fastened in the tunnel in such a way that that the so defined plane is near the Tunnel agent extending axis contains.
- This will be the Intake of air from the center of the tunnel and blowing out from air towards the middle of the tunnel Flow favors.
- the so runs defined plane vertically from top to bottom and divides the tunnel lengthwise into a right and a left Half.
- the plane thus defined is left arranged jet fan from top left to right down or right-handed jet fan of top right to bottom left diagonally through the Tunnel cross-section and thus through the tunnel center.
- the jet fan 1 shown in Figure 1 is mittles a bracket 2 on the tunnel ceiling 3 a 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 assemblies 6, 7 and the input 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, which are at their ends with Flanges 12, 13 are provided.
- the two flanges 12, 13 of a transition piece 10, 11 are at an angle of 3 degrees to 25 degrees apart.
- a conventional fan duct 4 and conventional nozzle arrangements 6, 7 are used, without the need for further special parts.
- the nozzle arrangements 6, 7 are conventional silencers with nozzles included in this Context are widespread.
- the jet fan 1 shown in FIG differs from that shown in FIG only by modified nozzle arrangements 18, 19, on their side facing the Lsymmetricerschcht 4 side 20 are formed bevelled.
- the inventive Inclination of the nozzle assemblies 18, 19 over the Fan shaft 4 results in this Embodiment by directly connecting the respective Beveled page 20 with the straight inlet 8 or Outlet side 9 of the fan shaft 4, without Interposition of a transition piece.
