Definitions

  • This invention refers to an apparatus for industrial ventilation of double enclosed spaces, from among the different large enclosed space air extraction apparatus.
  • This invention is characterised by a special construction of the apparatus, of cylindrical base hinged to the roof and that ventilates two different enclosed spaces, for example, a building and its false roof, by means of double channelling of the air, whether the extraction is controlled or not by remote control, whether forced or natural, or a mixture of both procedures.
  • Ventilation systems of the Venturi type those of simple air convection and, more recently, the spherical base spiral system type, are well-known.
  • the ventilation apparatus as the one disclosed in US 2569319 which is main aim is to obtain an apparatus wherein the fan and motor are not in the same conduit of evacuation, avoiding the accumulation of moisture, grease or other inflammable matter on the fan or motor.
  • the industrial ventilation apparatus of the present invention seeks to obtain an apparatus specially designed for industrial ventilation wherein is sought to obtain ventilation for double or more enclosed spaces using natural or forced ventilation, being made through a common roof.
  • This invention refers to an apparatus for industrial ventilation of double enclosed spaces, from among the different large enclosed space air extraction apparatus, both those that have natural direct ventilation and those with forced ventilation with air ducts.
  • This invention is characterised by a special construction of the apparatus, that carries out the ventilation of two separate enclosed spaces through the common roof,for example, in the case of a building and of its false ceiling, by means of a double extraction of air, whether this extraction is carried out in a controlled or in a natural manner, remote control preferably being used for this purpose in both cases. Besides this forced or natural ventilation, mixed ventilation with both procedures is possible.
  • this invention is characterised by a flue with a convex curved base, whether this be of spherical, cylindrical or ovoid sector; with barrel leading to a ring-shaped circular crown, fabricated in position at the intake of the apparatus, so that the ventilation of the under-roof area is carried out by the ring area and that of the lower enclosed space is carried out by the axial area, both areas sized for passing air according to the volume of each enclosed space to be ventilated and always with a single apparatus and very low pressure drops, the innermost duct also having a gate valve, closed in winter to avoid heat losses with which, this mixed ventilation becomes natural in this period, when the air extractor stops, the duct butterfly of the lower enclosed space closing and only the air coming from the under-roof enclosed space or chamber circulating, with which its humidity is extracted naturally.
  • Another alternative, that complements this invention, is that of having various air intakes at different levels of the lower enclosed space, in industrial premises that require a more precise extraction of air by layers; for example, with the purpose of breaking-up stratification, with which a number of intakes, at different heights, can be had.
  • the apparatus intake can have a different construction, being formed on a cylindrical section base with rectangle flanges, that have the air evacuation connection along all the generatrices of this sector, with an angle of its axis with respect to the radial plane of the cylinder identical to that of the incline of the roof.
  • the wings can also be the projecting section of a metal base sheet adequately holed, for passing the vent funnel.
  • both the mounting hole or holing of the metal sheet like that of the cylindrical sector can be of any angle, to be carried out in situ by the installers, according to requirements.
  • the flue is finished off with an upper cover, preferably of spherical sector, and the combination of the forced air shaft along with the space within the base spherical sector, the end cylindrical section of the funnel and the convexity of the cover, allow it to be positioned at a height not greater than half of the diameter of this funnel, with which the centre of gravity, unavoidably raised by the required upper end location of the fan, is lowered considerably, and the flue better withstands the pressure of the wind.
  • an upper cover preferably of spherical sector
  • natural ventilation extends to both enclosed spaces and can be made controllable, simply by eliminating the butterfly of the axial duct, while the motor fan can be substituted by a motor, adjoining the centre of the cover and fitted with an extended axis, and that incorporates a twin spiral screw so that the cover can be located in a large number of different heights, between its maximum extension and its contact with the upper end of the barrel of the funnel, that is, the possibility of millimetric adjustment exists from the closed position to the complete opening of the cover, a manual remote control or a regulating control connected to an anemometer, sufficing for this purpose.
  • Figure 1 is the variant with a flue of spherical sector base and/or fixed radial extension of the funnel.
  • Figure 2 is a schematic and partial representation of the previous figure, that shows the construction of the internal air shaft for both enclosed spaces, with two air intakes at a different level in the lower one of them, likewise one of the drawings showing the layout in the case of horizontal air evacuation.
  • Figure 3 is the variant of flue with cylindrical sector base and adjustable radial extension of the funnel, depending on the equivalent angle of the roof.
  • Figure 4 is the controllable forced ventilation variant, without the butterfly and in which the fan is substituted by a motorized raising and closing of the cover.
  • the present invention refers to an industrial ventilation apparatus for double enclosed spaces, from among the different air extraction apparatus using natural or forced ventilation; essentially characterised by carrying out the ventilation of the height-separated enclosed spaces, through the common roof, whether with forced and controlled extraction, natural or mixed, based on a spherical or ovoid cylindrical sector base flue (1), whether with rectangular flanges (1.1) or with a projecting section of a large holed metal sheet (1.2), to admit a section of the vent funnel or barrel (2) radially positioned with a ring-shaped circular crown, constructed in position at the intake of the apparatus, so that the ventilation of the enclosed space (3) immediately below the roof (4) is carried out by the ring-shaped duct (2.2) and that of the enclosed space (5) below the false ceiling (6) is carried out by the axial duct (2.1) of the barrel (2), both air passage openings being sized according to the volume of each enclosed space (3) and (5) to be ventilated, with a single apparatus and minimum pressure losses
  • At least two air intakes (2.2.1) and (2.2.2) are set up, connecting the consecutive ends of these ducts at their respective bases, with radial rods, these reaching the same different levels (5.1) and (5.2) of the enclosed space (5) below, that break up its stratification.
  • the air evacuation opening (1.3) is placed along the generatrices of this sector, with an angle of its axis with respect to the radial plane of the cylinder identical to that of the roof (4), of whatever incline, whether to be previously measured and the opening made in a workshop or whether to be carried out in situ by the installers, according to requirements.
  • the flue is finished off with an upper cover (7) preferably of spherical sector, and that may or may not incorporate a plate (7.1) internal to this cover, of discoid configuration, whether truncated-conical or whether corrugated curved, that minimizes air blowback in the cover and that is held at the perimeter by anti-vibration rubber (7.2) in a horizontal "U".
  • an upper cover (7) preferably of spherical sector, and that may or may not incorporate a plate (7.1) internal to this cover, of discoid configuration, whether truncated-conical or whether corrugated curved, that minimizes air blowback in the cover and that is held at the perimeter by anti-vibration rubber (7.2) in a horizontal "U".
  • the extraction can drive air into one or both of the two enclosed spaces (3) and (5), in this latter case simultaneously into, at least, the levels (5.1) and (5.2).
  • a different variant is the one that allows natural ventilation to be extended to both enclosed spaces (3) and (5)and to convert this in controllable, by eliminating the butterfly (2.3) of the axial duct (2.1) and substitution of the extractor (8) motor (8.1), by another motor (9) adjacent to the centre of the cover and designed with an extended axis (9.1) and that incorporates a twin spiral screw (9.2) for multiple positioning of the cover opening (7) or with the closing of this latter directed by a manual remote control or regulation by means of an electronic circuit connected to an anemometer, not shown in the figure.
  • the electrical supply (9.3) to the motor (9) is carried out through the interior part of the cover (7), by means of a channelling (7.3) and between this and any bracket of the cover (7) its rotation is prevented, leaving the vertical displacement of the cover (7) between the extreme positions of the twin spiral screw (9.2) as the only possible movement.
  • the layout of the air outlet or of its intake can also be horizontally set up, direction, by simple access holing of the opposing part of the construction, main wall and also partitioning of the air chamber. With which the evacuation of the direct heat accumulated in this chamber in the facades oriented South, and everything previously said being valid, except for the change of positioning of the apparatus, is achieved.
