Definitions

  • the present invention relates to a ventilation arrangement for ventilating a building interior.
  • Air conditioning or other mechanical ventilation systems can be used to provide ventilation to buildings to address these difficulties. However, such systems consume electricity and can, therefore, be relatively expensive to operate.
  • One prior arrangement is to provide a duct extending from just above roof level into a building, with the upper end of the duct connecting to outwardly facing openings extending around the duct. During use air can enter the windward side of the duct through respective openings, with stale air exiting from the building through respective openings on the leeward side of the duct.
  • the duct is divided by radial dividers, which could for instance divide the ducting into four quadrants, with the quadrant nearest the windward side receiving the most air to ventilate the building, whilst the majority of air extracted from the building exits through the opposite quadrant on the leeward side of the arrangement.
  • radial dividers could for instance divide the ducting into four quadrants, with the quadrant nearest the windward side receiving the most air to ventilate the building, whilst the majority of air extracted from the building exits through the opposite quadrant on the leeward side of the arrangement.
  • a ventilation arrangement for ventilating a building according to the subject-matter of claim 1.
  • the closure arrangement may be configured to permit partial closure of the ventilation openings.
  • the ventilation arrangement may be substantially polygonal in plan view, with ventilation openings and a corresponding closure arrangement, for each side of the polygon.
  • the ventilation arrangement may be substantially circular or oval in plan view.
  • the closure members may be connected to an actuator member such that the closure members are all simultaneously movable between the open and closed conditions.
  • the closure arrangement may be manually operable and/or operable by an electric motor, or actuator.
  • the closure arrangement may be operable from the building interior, and a control member may extend from the actuator member into the building.
  • Automatic control means may be provided for automatically moving the closure arrangement between the open and closed conditions as required.
  • the automatic control means may be connected to a weather station or detectors so as to automatically move the closure arrangement to or towards a closed position when bad weather is forecast or detected.
  • the automatic control means may be connected to a timer so as to automatically move the closure arrangement between open and closed conditions for particular times or seasons of the year.
  • Figs. 1 to 4 of the drawings show a first ventilation arrangement 10 according to the invention for ventilating an interior 12 of a building.
  • the ventilation arrangement 10 is mounted on a roof 14 of a building and extends through the roof space 16 to the building interior 12.
  • the arrangement 10 comprises a duct 18 which extends vertically to above the roof 14.
  • the duct 18 is divided into four quadrants by vertical divider plates (not shown). These plates divide the duct such that air on the windward quadrants will enter the arrangement 10, whilst air on the leeward side will exit from the interior 12 through the arrangement 10.
  • the duct 18 is of square cross section, but other cross sectional shapes such as circular could be used.
  • the top end of the duct 18 is closed by a turret 20. Beneath the turret 20 a louvre arrangement 22 is provided which defines five downwardly and outwardly extending openings 24 extending from the interior of the duct 18 to atmosphere.
  • a closure arrangement 26 which comprises a central bar 28 extending upwardly through the duct 18 to an upper plate 30.
  • the bar 28 may house the divider plates.
  • Extending downwardly on each side from the plate 30 is an inner louvre arrangement 32.
  • the inner louvre arrangement 32 is of a similar configuration to the outer louvre arrangement 22 but is set inwardly and comprises a first downwardly extending section 34 from which an outwardly and downwardly inclined second section 36 extends to a downwardly extending third outer section 38.
  • each third outer section 38 closes a respective one of the openings 24.
  • the third outer section 38 In a lower open position as shown in Fig. 1 , the third outer section 38 is clear of the respective openings 24, and lies parallel to the inner first section 44 of the louvre arrangement 22.
  • Fig. 4 shows a partially open configuration, with the third outer sections 38 partially closing the respective openings 24.
  • the bar 28 extends within the duct 18 to a little below the outer louvre arrangement 22 and connects to an actuator 42 mounted on a further bar 44 which extends downwardly to a lower part of the duct 18.
  • the actuator 42 can be mechanically operable by a connection to the further bar 44 extending into the building interior 12.
  • the actuator 42 can be controlled by an electrical motor (not shown).
  • a guide wheel or a geared rack can be used to provide vertical movement of the central bar 28.
  • Ductwork 46 extends beneath the duct 18 and leads to an airflow control arrangement 48 with dampers 50 for controlling the flow of air between the exterior and interior 12 of the building. Beneath the air flow arrangement 48 a grille 52 is provided in the ceiling 54.
  • a programmable automatic control box 56 is provided for automatic actuation of the closure arrangement 26.
  • the control box 56 can be programmed by season allowing for instance a 25% opening in winter mode when lower external temperatures provide a greater driving force for natural ventilation.
  • the closure arrangement could be programmed to be 50% open, and during summer mode to provide maximum ventilation, the closure arrangement can be set to 100% open.
  • the control box 56 could also be linked to a weather station, which could be locally mounted. This could provide a control signal prior to or during very poor weather conditions. These conditions could be strong winds, heavy rain, snow or very low external temperatures. This can particularly prevent for instance snow being carried into the arrangement 10.
  • Figs. 5 to 7 of the drawings show a second ventilation arrangement 100 according to the invention which is similar in many respects to the arrangement 10, and only the differences will be described.
  • a louvre arrangement 102 is provided which defines eight openings 104 on each side of the duct 106.
  • the louvre arrangement 102 again comprises a fixed outer louvre arrangement 108 and a movable inner louvre arrangement 110.
  • the upper ends of the inner louvre arrangement 110 on each side are attached adjacent the corner of the square duct 106, to an end of the respective arm of a horizontally extending cruciform support 112.
  • a downwardly extending bar 114 is provided at the centre of the support 112, and the bar 114 is operatively engageable with a linear actuator 116, for raising and lowering the support 112.
  • the linear actuator 116 is mounted on a support plate 118 which extends across part of the top of the duct 106.
  • a solar panel 120 is provided on the top end of a turret 122 which closes the top end of the duct 106.
  • the solar panel 120 may power the actuator 116, and any control or sensor equipment for the arrangement 100.
  • any required position of the inner louvre arrangement 110 can be chosen between the fully closed position shown in Fig. 6 and the fully open position shown in Fig. 5 , to vary the amount of ventilation into and out of the duct 106.
  • the duct may be other than of square cross section, and could be a different polygonal shape, or circular or oval.
  • a different number of openings could be provided by the louvre arrangement.
  • the actuator could be provided at a different location, such as under the turret or any other capping provided for the arrangement.
