Definitions

  • a method of retrofitting a smoke extractor system to a building having a plurality of storeys which are interconnected by a lift shaft comprising the steps of: installing a mechanical ventilation device to the lift shaft, the mechanical ventilation device having an inlet at or adjacent to the lift shaft and an outlet external to the building; and providing a smoke access path on each storey which couples each storey to the lift shaft and providing a smoke detector on each of the plurality of storeys; installing a controller for activating the mechanical ventilation device and opening and/or closing at least one of the smoke access paths; providing a first air access path between the stairwell and the exterior of the building comprising an automatically opening vent, openable by the controller; providing a second air access path between the stairwell and the lift shaft; the mechanical ventilation device, lift shaft and smoke access path defining a smoke extraction system such that in the event of smoke being detected by a said smoke detector on at least one of the plurality of storeys, there is a smoke escape
  • This method allows for a smoke extractor system to be retrofitted to a building where a majority of the communal areas of the building are not adjacent to the exterior of the building.
  • lift shafts are typically formed as an axially extending conduit through the building intersecting each storey and being adjacent to the exterior of the building at an upper portion of the lift shaft, they represent a suitable pathway for extracting smoke from a building.
  • the smoke pathway allows for smoke to be ventilated from the building and therefore prevent, limit or reduce the risk of smoke inhalation by escaping occupants of the building.
  • each smoke access path may be open or openable.
  • the smoke access path may have a damper valve.
  • each smoke access path is only open in the event of smoke being present on the associated storey. Providing for each smoke access path to be open or openable allows for smoke to move from the communal access area of each storey where it may be present to the lift shaft, thus reducing the risk of smoke inhalation to those in the communal access corridor.
  • the smoke access path having a damper valve may allow for the smoke access path to be set interchangeably to either to the open condition, and so provide the benefits as previously described, or to the closed condition and thus prevent or limit smoke which may be present in the lift shaft from entering the storey where the smoke is not present. In this way smoke can be prevented or limited from spreading or infiltrating to other storeys and so occupants of the building present on those storeys can be at a lower risk of smoke inhalation.
  • the controller allows for the remote and/or automatic operation and/or activation of the smoke extractor system.
  • the smoke detector allows for the automatic detection of smoke and thus permit the automatic operation and/or activation of the smoke extractor system.
  • the method may further comprise the step of an associated lift car of the lift shaft being driven at or adjacent to a ground storey of the building in the event of smoke being detected.
  • the positioning of the lift car at or adjacent to the ground storey of the building results in a majority of the lift shaft being unobstructed and thus is a more effective path for the movement of smoke.
  • the method may further comprise the step of providing sealant between the lift shaft and the plurality of storeys.
  • the provision of sealant reduces or restricts the number of smoke leakage paths that may exist between the lift shaft and the plurality of storeys. This may prevent or limit smoke present in the lift shaft from accessing the or each storey which does not have smoke present.
  • the method may further comprise the step of installing a lift-shaft-modification apparatus to the lift shaft, in order that the lift shaft can act as a pressurised smoke shaft.
  • the lift-shaft-modification apparatus may comprise any or all of: mechanical lifting equipment; lift car; guide rails; wiring; lift controller; pulleys; cables; tracks; and counterweights.
  • the lift-shaft-modification apparatus may comprise at least one restraining device for restraining movable components within the lift shaft upon activation of the smoke extraction system.
  • lift-shaft-modification apparatus may advantageously allow older-style lift shafts to be retrofitted with a smoke extraction system.
  • the lift shaft needs to be able to act as a pressurized smoke shaft for the building, and the existing lift cab and lifting mechanisms may not be suitable for this purpose.
  • the lift-shaft-modification apparatus can serve to prevent these leakages, and also improve the smoke extraction efficiency of the retrofitted lift shaft.
  • each vent may have a damper valve.
  • the retrofittable apparatus may further comprise at least one smoke detector.
  • the retrofittable apparatus may preferably further comprise a lift-shaft-modification apparatus to the lift shaft, in order that the lift shaft can act as a pressurised smoke shaft.
  • the lift-shaft-modification apparatus may comprise any or all of: mechanical lifting equipment; lift car; guide rails; wiring; lift controller; pulleys; cables; tracks; and counterweights.
  • the lift-shaft-modification apparatus may comprise at least one restraining device for restraining movable components within the lift shaft upon activation of the smoke extraction system.
  • the lift-shaft-modification apparatus beneficially serves to improve the smoke extraction efficiency of the lift shaft, if applied correctly to the lift shaft.

  • the building may further comprise a stairwell.
  • the building may further comprise a first air access path positioned between the exterior of the building and the stairwell.
  • the building may further comprise a second air access path positioned between the stairwell and the lift shaft.
  • the building may further comprise a smoke detector positioned on each of the plurality of storeys and operatively connected to the controller.

  • the mechanical ventilation device 18, which may be or have an extractor fan, having an inlet 20 within the lift shaft 54 and an outlet 22 exterior to the lift shaft 54 and building 14 may cause a lowering of the pressure within the lift shaft 54 through the extraction of air and/or smoke from within the shaft.
  • the controller 36 may send a signal to the first air access path 28, which may be an automatically opening vent 28 having an actuator 34.
  • the actuator 34 may be activated so as to cause an opening of the automatically opening vent 28 and thus an air access path between the exterior of the building 14 and the stair well is created.
  • the second air access pathway which may take the form of at least one vent 24, may also be opened in the event that the second air access pathway is openable and/or closable.
  • the lowering of the pressure within the lift shaft 54 by the mechanical ventilation device 18 may have the effect that the pressure is lower within the lift shaft 54 than within each of the storeys 16.
  • this pressure differential or gradient creates a driving force for the smoke and/or air within the storey 16 to be extracted to the lift shaft 54.
  • the smoke may be moved upwards along a longitudinal or vertical extent of the lift shaft 54 and extracted via the inlet 20 and outlet 22 of the mechanical ventilation device 18 and out of the lift shaft 54 and building 14 to the exterior of the building 14. This therefore creates a smoke escape pathway.
  • the movement of the smoke up along the lift shaft 54 may be the result of the lower pressure proximal to the inlet 20 of the mechanical ventilation device 18 as well as the buoyancy effect generated by the smoke being warmer than the ambient air temperature within the building 14. This removal of smoke from the or each smoke storey 16, and thus from the communal areas of each storey 16, may help to prevent cases of smoke inhalation among occupants of the building 14.
  • the positioning of the damper valve of the smoke escape path in a closed condition on a storey 16 where smoke is not present can prevent or limit the movement, spreading or infiltration of smoke, which may be present in the lift shaft 54, to a storey 16 where smoke is not already present.
  • the differential between the pressure of the lift shaft 54 and each storey 16 may be such that smoke is prevented limited from moving, spreading or infiltrating to the or each storey 16 where smoke is not present.
  • the first air access path 28 being opened allows for any smoke which may have entered the stairwell 70 from any of the storeys 16 to exit from the stairwell 70 and the building 14. This movement of smoke may be caused by the buoyancy effect in the similar way as described for the smoke in the lift shaft 54.
  • the second air access path is positioned only at, adjacent to or proximal to the ground storey 42 of the building 14, there may therefore be a supply or movement of clean air from the exterior of the building 14 and through a majority of the stairwell 70. This clean air may help to prevent or limit escaping occupants of the building 14 from suffering from smoke inhalation.
  • a smoke detector 38 Whilst a smoke detector 38 is described as detecting the presence of smoke and then triggering or activating the smoke extractor system 12, it is appreciated that the system 12 may alternatively have a heat detector or sensor such as a thermocouple positioned on each storey 16 which may detect heat on a storey 16 and then activate the smoke extractor system 12 in the same or similar way as previously described. Additionally or alternatively, the smoke extractor system 12 may be activated by a manual fire alarm activation device such as a pull station, which may be positioned on each of the storeys 16. If a pull station is triggered on a storey 16 then the smoke extractor system 12 may be activated in the same way as previously described.
