Definitions

  • the invention relates to a fan unit for clean rooms according to the Preamble of claim 1.
  • WO-A-93/09389 is also a fan unit with a annular air flow channel known in the housing.
  • the invention has for its object the generic fan unit to be trained in such a way that it is structurally simpler and less expensive Way, taking into account the specified grid size optimal ventilation is achieved by the fan unit.
  • the air flow channel is aligned in the vertical direction so that the suctioned by the fan and clean air discharged into the housing in the air flow channel flows down.
  • the height of the air flow channel can be varied.
  • the grid size of the fan unit is not changed, so that optimal sound absorption while maintaining the grid dimension is achieved.
  • the partition can be placed between the opposite ones Simply mount the housing side walls. Between the floor and the filter located at a distance below a second air flow channel is formed. The down from Clean air emerging from the air flow duct hits the filter. The clean air flows due to the resulting dynamic pressure also under the floor in the further air flow space defined by it. This is a very simple constructive uniform flow distribution over the surface of the filter.
  • the fan unit has a housing 1, which is advantageous is cuboid.
  • the housing 1 has a right angle mutually lying side walls 2 to 5, the are connected by a blanket 6.
  • the sidewalls and the ceiling are each level.
  • the side walls 2 and 4 are each by profile parts formed, which have a C-shaped cross section (Fig. 1 and 2).
  • the ceiling 6 is formed by a plate that on the upper edges or legs of the side walls 2 to 5 rests and connected to them in a suitable manner is.
  • a fan element 7 is suspended from the ceiling 6 attached. It consists of an intake nozzle 22, a Impeller 7, a drive motor 10, a base plate 9 and from stud bolts 8.
  • the fan 7 is advantageous a radial fan with a preferably free-running Wheel that is curved backwards in the direction of rotation Has shovels.
  • the radial fan has the advantage that it only has a very small dynamic pressure component and has a high efficiency.
  • the base plate 9 has, as shown in Fig. 1, square Outline, is flat and is located approximately in half height in the housing 1. In the axial direction of the fan 7 seen, the plate 9 covers the fan 7 of down from. The studs 8 are in the corners of the plate 9 provided. On it the drive motor 10 stands for Fan 7 on. The drive motor 10 is preferred an external rotor motor. It partially rises up into the Fan 7 (Fig. 2).
  • Plate 11 is provided, which has a rectangular outline.
  • the Plate 11 is on its two long sides on the side walls 3 and 5 attached.
  • On the narrow sides of the plate 11 upwardly projecting walls 12 and 13 are provided which extend vertically upwards from the plate 11 and end at a distance from the ceiling 6 (Fig. 2).
  • the walls 12, 13 are also spaced from the side walls 2 and 4 of the housing 1. As shown in FIG. 1, extend the walls 12, 13 between the opposite one another Long sides 3 and 5 of the housing 1 through flat plates are formed.
  • the walls 12, 13 lie on both sides of the fan 7 at a distance from it.
  • the Walls 12, 13 are suitably on the long sides 3, 5 of the housing 1 attached.
  • the base plate 9 of the fan 7 can also on the Rest plate 11 or form a unit with it.
  • the side walls forming the narrow sides of the housing 1 2 and 4 are each formed by C-shaped profile parts. They are on the inside with sound-absorbing material 14 covered, for example mineral wool, Foam and the like can be.
  • This sound absorbing Material 14 advantageously fills the C-profile parts completely from (Fig. 1 and 2). Between the walls 12, 13 and the sound-absorbing material 14 are about the entire width of the housing 1 extending air flow channels 15 and 16 formed by which the from Fan 7 coming clean air is guided downwards.
  • the two air flow channels 15, 16 are via one Gap 17, 18 with the central fan 7 Housing part 19 fluidly connected.
  • the two Columns 17, 18 also extend over the entire Width of the case 1.
  • the height of the air flow channels 15, 16 depends on the desired silencing requirements from. The lower the air flow channels 15, 16, the lower the sound attenuation same width of the air flow channels. In this way can by choosing the height of the walls 12, 13 and / or by choosing the distance of the walls 12, 13 from the neighboring ones Soundproofing layers 14 the optimal soundproofing can be set easily and inexpensively.
  • the noise reduction measure is taken about the height of the unit, i.e. at the Flow through the vertically arranged air flow channels 15, 16.
  • the ceiling 6 has an installation opening, in which the fan element is inserted becomes.
  • the suction nozzle 22 has a peripheral edge, with which the fan element along the edge of the installation opening rests on the blanket 6 and on it in a suitable manner Way is attached.
  • a Protective grille 23 is provided on the suction nozzle 22 .
  • the sides of the sound-absorbing side facing the walls 12, 13 Layers 14 are flat, so that through the air flow channels 15, 16 flowing clean air not disturbed becomes.
  • the walls 12, 13 and the side walls 2, 4 with the Soundproofing layers 14 are advantageously parallel to one another, so that over the length of the air flow channels 15, 16 the same flow conditions prevail.
