Definitions

  • the invention relates to a fan unit for clean rooms according to the preamble of claim 1.
  • the air flow duct adjoining the fan is directed transversely to the fan axis.
  • the air flow channel consists of two sections lying parallel to one another, so that the clean air must be deflected by 180 ° during the transition from one section to the other. In this way, the length of the flow path of the clean air required for the desired sound absorption is created.
  • Such fan units are usually installed in a grid dimension, so that the external dimensions of the fan unit are predetermined. For this reason, the flow path of the clean air transversely to the axis of the fan can not be chosen arbitrarily large. The sound absorption is therefore limited taking into account the grid dimension.
  • the invention has for its object to design the generic fan unit so that optimal sound attenuation is achieved in a structurally simple and inexpensive manner, taking into account the predetermined pitch of the fan unit.
  • the air flow channel is not oriented in the transverse direction but in the height direction.
  • the clean air sucked in by the fan and released into the housing flows from top to bottom in the air flow channel.
  • the height of the air flow channel can be varied depending on the desired level of sound absorption.
  • the grid dimension of the fan unit is not changed, however, so that optimum sound damping is achieved while maintaining the grid dimension.
  • the fan unit has a housing 1, which is advantageously cuboid.
  • the housing 1 has side walls 2 to 5 which are at right angles to one another and are connected to one another by a ceiling 6.
  • the side walls and the ceiling are each flat.
  • the side walls 2 and 4 are each formed by profile parts which have a C-shaped cross section (FIGS. 1 and 2).
  • the ceiling 6 is formed by a plate which rests on the upper edges or legs of the side walls 2 to 5 and is connected to them in a suitable manner.
  • a fan element 7 is suspended from the ceiling 6. It consists of an intake nozzle 22, an impeller 7, a drive motor 10, a base plate 9 and stud bolts 8.
  • the fan 7 is advantageously a radial fan with a preferably free-running wheel which has blades which are curved backwards in the direction of rotation.
  • the radial fan has the advantage that it has only a very small dynamic pressure component and is highly efficient.
  • the base plate 9, as shown in FIG. 1, has a square outline, is flat and is located approximately halfway up the housing 1. Seen in the axial direction of the fan 7, the plate 9 covers the fan 7 from below.
  • the stud bolts 8 are provided in the corners of the plate 9.
  • the drive motor 10 for the fan 7 stands on it.
  • the drive motor 10 is preferred an external rotor motor. It partially projects upwards into the fan 7 (FIG. 2).
  • a plate 11 extending between the side walls 3 and 5 is provided in the housing 1 and has a rectangular outline.
  • the plate 11 is fastened to the side walls 3 and 5 on its two longitudinal sides.
  • 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 apart from the side walls 2 and 4 of the housing 1.
  • the walls 12, 13 extend between the opposite longitudinal sides 3 and 5 of the housing 1, which are formed by flat plates .
  • the walls 12, 13 lie on both sides of the fan 7 at a distance from it.
  • the walls 12, 13 are fastened in a suitable manner on the longitudinal sides 3, 5 of the housing 1.
  • the base plate 9 of the fan 7 can also rest on the plate 11 or form a unit with it.
  • the side walls 2 and 4 forming the narrow sides of the housing 1 are each formed by C-shaped profile parts. They are covered on the inside with sound-absorbing material 14, which can be mineral wool, foam and the like, for example. This sound-absorbing material 14 advantageously fills the C-profile parts completely (FIGS. 1 and 2). Between the walls 12, 13 and the sound-absorbing material 14 extending air flow channels 15 and 16 are formed over the entire width of the housing 1, through which the clean air coming from the fan 7 is guided downwards.
  • the two air flow channels 15, 16 are fluidly connected via a gap 17, 18 to the central housing part 19 having the fan 7.
  • the two gaps 17, 18 also extend over the entire width of the housing 1.
  • a high-performance filter (not shown) is fastened to the underside of the housing 1 in a known manner and has the same cross-sectional area as the housing. The air sucked in by the fan 7 flows through this high-performance filter into the clean room located below the high-performance filter.
  • the height 20 of column 17, 18, i.e. the distance between the upper edge of the walls 12, 13 and the ceiling 6 is chosen so that the flow rate in the columns 17, 18 is less than or at most equal to the flow rate in the air flow channels 15, 16. This measure ensures that only minimal pressure losses occur.
  • the height of the air flow channels 15, 16 depends on the desired sound attenuation requirements. The lower the air flow channels 15, 16, the lower the sound absorption with the same width of the air flow channels. In this way, by choosing the height of the walls 12, 13 and / or by choosing the distance of the walls 12, 13 from the adjacent soundproofing layers 14, the optimum soundproofing can be set simply and inexpensively.
  • the noise reduction measure takes place over the height of the unit, i.e. when flowing through the vertically arranged air flow channels 15, 16.
  • the required sound damping can thus be set very easily by different heights, without thereby changing the grid dimension of the fan unit.
  • different soundproofing qualities can be obtained very easily.
  • the clean air emerging from the air flow channels 15, 16 hits the high-performance filter (not shown). Due to the resulting back pressure, the clean air also flows under the plate 11, so that a uniform flow distribution over the surface of the filter is achieved.
  • the ceiling 6 has an installation opening into which the fan element is inserted.
  • the suction nozzle 22 has a peripheral edge with which the fan element rests on the ceiling 6 along the edge of the installation opening and is fastened to it in a suitable manner.
  • a protective grille 23 is provided on the suction nozzle 22.
  • the sides of the sound-absorbing layers 14 facing the walls 12, 13 are flat, so that the clean air flowing through the air flow channels 15, 16 is not disturbed.
  • the walls 12, 13 and the side walls 2, 4 with the sound-absorbing layers 14 are advantageously parallel to one another, so that the same flow conditions prevail over the length of the air flow channels 15, 16.
