Definitions

  • the invention relates to a ventilation component, comprising a channel-shaped housing with peripherally arranged housing walls, wherein in the housing at least one fan, in particular a centrifugal fan, and a fan seen in the flow direction upstream diaphragm are arranged, wherein the aperture an opening for the passage of the flowing medium Having the intake of the fan.
  • a centrifugal fan includes an impeller driven by a drive motor.
  • the impeller usually has a cover plate and a support disc, between which impeller blades are arranged.
  • the air is usually sucked parallel to the drive axis of the centrifugal fan and deflected by the rotation of the radial impeller by 90 ° and blown out radially.
  • the radial fans used in the present field do not have a housing disposed around the impeller.
  • the slotted silencer is mounted so that the distance between the diaphragm and the downstream side of the slotted silencer is at least half the diameter of the impeller.
  • this requires on the one hand a high housing length and on the other hand a higher sound power, which is not desirable.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a ventilation component, which has a lower sound power.
  • the housing walls at least one circumferential, preferably at the housing walls provided, at least one, in particular central, flow channel releasing, Schalldämm- and / or Soundproofing material is provided.
  • the inventive design is the Soundproofing improved in the channel-shaped housing. Furthermore, under certain circumstances, an improved sound insulation can be achieved.

  • the flow is accelerated before the orifice to the speed level in the region of the opening provided in the orifice (orifice flow). If the cross section of the flow channel is constant over its entire length, the flow is accelerated directly. If, for example, the cross section of the flow channel decreases steadily in the flow direction, the flow in the flow channel is steadily accelerated. Thus, the fan can work more effectively, so that the efficiency of the fan is increased.
  • the sound insulation and / or sound damping material can be installed in a very little to no distance to the upstream side of the panel. In the latter case, the outflow side of the sound insulation and / or sound damping material is applied to the inflow side of the diaphragm. This reduces the sound power.
