Definitions

  • the present invention relates to a system for ventilating and / or de-smoking a staircase connected in a building section with a multi-storey building according to the preamble of claim 1.
  • Such a system is in EP 995 955 A2 disclosed.
  • the ventilation openings between shaft and staircase mounted in closed shafts on the uppermost elevator level at best assume an alibi function, without sufficient ventilation or even smoke extraction and thus the necessary operational safety To take care.
  • hoistway ventilation and smoke extraction systems which control the natural ventilation and smoke extraction of the hoistway via a window or louver in the shaft head or engine room are known in the prior art.
  • a system in the elevator shaft of a building as described with in a fire section next to each other (ie adjacent to each other) arranged Stairwell and elevator shaft could be used, it would not contribute to the safe operation of the elevator system due to the described lack of thermal in the elevator shaft, or can not ensure the safety of the elevator users.
  • staircase and the elevator shaft lie directly next to one another and the individual floors are not subdivided into different fire sections.
  • staircase and elevator shaft are located entirely in a common volume or fire compartment.
  • At least two ventilation openings are provided, which connect the elevator shaft with the staircase at different vertical positions, in particular on different floors.
  • the stairwell may be provided with ventilation openings connecting to the elevator shaft.
  • a first of the ventilation openings is located in a lower portion of the elevator shaft, can be arranged in particular in the area of a lowermost elevator floor or in the area of the shaft pit.
  • a second ventilation opening is arranged in an upper section of the elevator shaft, and may be arranged in particular in the region of an uppermost elevator platform.
  • a fan for conveying air from one of the areas, staircase or elevator shaft, in the other of the areas, elevator shaft or staircase is arranged in the area of at least one of the ventilation openings.
  • the at least one fan may be arranged in the region of the first ventilation opening arranged in a vertically lower region of the elevator shaft.
  • a fan in the region of the first ventilation opening and a second fan in the region of the second ventilation opening.
  • These fans can be operated in particular in such a way that they provide for a circulation of air through the elevator shaft and through the adjacent staircase.
  • a smoke extraction can be part of the system that connects the elevator shaft, eg via a smoke control or a smoke extraction window, with the outside air arranged outside the building, and the one holding the smoke extraction opening in a normal position holding Has closing element.
  • a smoke extraction can in case of fire or in the case of other smoke in the elevator shaft emerging or in this penetrating smoke, for example via the opening between elevator shaft and top elevator level on the smoke control on this elevator level (or in the stairwell on an intermediate level) to the outside Dismantled building, this in particular supported by the caused by the at least one fan air movement and the resulting air flow.
  • the lift shaft e.g. via a Nachströmklappe or Nachströmi near the at least one fan in the lower region of the elevator shaft with the outside of the building arranged outside air and having a Nachströmö réelle in a normal position closed holding closing element.
  • fresh air from outside the building for ventilation, smoke extraction or smoke dilution can be tracked via such an afterflow opening and can enter the elevator shaft.
  • the system may also have a controller that is set up to detect a ventilation and / or smoke extraction requirement, and which, upon detection of such a requirement, drives the at least one fan for startup.
  • a controller that is set up to detect a ventilation and / or smoke extraction requirement, and which, upon detection of such a requirement, drives the at least one fan for startup.
  • the controller may also be in communication with suitable sensors which give the controller sensor messages which indicate certain conditions of the system.
  • sensors may be smoke detectors, air quality sensors, temperature sensors, humidity sensors or the like, for example.
  • a data connection of Control with a fire alarm system or building control center is conceivable, from which the controller then receives status data or to which it passes the corresponding status data.
  • the controller can also be connected to a manual activation, such as a switch or button, via which an action of the controller can be triggered.
  • the controller can be connected to drives for opening / closing the optional existing smoke extraction and / or Nachströmö réelleen to operate these components depending on a detected condition centrally.
  • an air quality sensor analyzing the supply air flowing through this ventilation opening into the elevator shaft can be provided, e.g. Upon detection of toxic components or too low an oxygen content, a message to the controller outputs, which in turn causes the closure element spent in a ventilation opening closing position and the fan is stopped. Also, e.g.
  • a smoke detector, air quality sensor or humidity sensor may be arranged in the interior of the elevator shaft, which emits a signal to the controller on detection of smoke, high humidity or harmful gases, which in turn triggers an opening of - optionally present - smoke extraction and controls the fan, the to drive air contaminated with smoke, high humidity or harmful gases in the direction of this smoke extraction opening.
  • the controller can trigger the opening of the Nachströmö réelle so that enough fresh air can flow.
  • the fan arranged in the region of at least one of the ventilation openings can usually also be sufficient for fans in the area of both ventilation openings.
  • the circulation fans can also be arranged in the interior of the elevator shaft in intermediate areas between the ventilation openings or fans on the outside of the elevator car facing the elevator shaft (eg on the outer walls of the elevator car). In principle, there may even be cases in which, for the purposes of bringing the circulation into circulation and / or maintaining it, recourse is exclusively made to fans arranged between the ventilation openings in the elevator shaft (possibly on the elevator car).
  • a method for venting and / or de-smoking a lift shaft by appropriately controlled operation of the at least one or more fans (s) arranged in the areas of the ventilation opening.
  • a building section 1 which includes an elevator shaft 2 of an elevator system with vertically movable elevator car 3 and a directly adjacent to the elevator shaft 2 arranged with the elevator shaft 2 located in a single, common fire section staircase 4.
  • ventilation openings 5 and 6 are provided in a vertically lower area and a vertically upper area, which connect the elevator shaft 2 to the staircase 4.
  • a fan 7 is arranged, which is installed here directly in the ventilation opening 5. This fan 7 serves to convey air from the staircase 4 in the elevator shaft 2, so as to drive an air circulation and to ensure that fresh air from the staircase 4 enters the elevator shaft 2, and so in particular with the elevator shaft 2 in the air exchange to ventilate standing elevator car 3.
  • the at least one fan 7 may in particular be in communication with a controller which drives it only when a corresponding requirement is detected, eg due to sensor signals emitted by sensors connected to the controller, or if a manual request, eg by Pressing a switch is detected.
  • Fig. 1 is shown in the presence of a ventilation requirement by activating the arranged on the lowest level elevator in the local ventilation opening 5 in the wall of the elevator shaft 2 fan 7 and mounted on the top elevator level ventilation opening 6 between the elevator shaft 2 and staircase 4, a - in the figures Circumferential indicated by circulating arrows - circulating air circulation between the separated only by partially air-tight elevator doors volumes of elevator shaft 2 and staircase 4.
  • a further fan 8 can be arranged in the area of the ventilation opening 6 (see FIG. Fig. 2 with the fan 8) installed there in the ventilation opening 6, which conveys the air from the elevator shaft 2 into the staircase 4 so as to achieve sufficient air circulation for supplying the elevator shaft 2 with fresh air from the staircase 4.
  • a situation is shown in which there is a fire 9 in the elevator shaft 2, for example by a cable fire, the smoke 10 in the elevator shaft 2 releases.

  • a further inflow opening 17 can be seen, which connects the elevator shaft 2 with the outside atmosphere outside the building.
  • the inflow opening 17 can connect directly to the surroundings of the building.
  • an air duct can be provided which, for example, overcomes a longer distance in the building and thus connects an elevator shaft 2 located in the interior of the building with the outside air outside the building.
  • Nachströmö réelle 17 may optionally be provided and either alternatively to the Nachströmö réelle 15 or in addition to this.
  • the inflow opening 17 can also be used, in particular, to supply fresh air to the elevator shaft 2 and thus also to the elevator cabin 3 in gas exchange with it.
  • a further fan 18 may be arranged in this, if necessary, can be operated for the tracking of fresh air, for example, controlled by the controller.
  • the Nachströmö réelle 17, a closure flap 19 (see Fig. 4 , where there the fan 18 is not shown), by which it is normally closed to prevent unnecessary and then unwanted entry of outside air and so prevent heat loss or heat input into the climatically controlled building inside.
  • Fig. 4 It is shown that the system can be supplemented by smoke and air quality sensors 13 in the intake area of the air in the elevator shaft 2 advancing fan (not shown in this figure for clarity) and by closing flaps 14, 16 for closing the ventilation opening 5, 6. If a contamination of the intake air is detected in the intake area of the fan (not shown in the figure) in the ventilation opening 5 via the sensors 12, 13, this contaminated air is drawn into the elevator shaft 2 and a supply thereof to the elevator car 3 thereby avoiding that by the controller connected to the sensors 12, 13 a shutdown of the fan 5 arranged in the ventilation opening 5 (not shown in the figure) and also one in the ventilation opening 6 arranged fan (also not shown in the figure for reasons of clarity) and closing the ventilation openings 5, 6 by closing the flaps 14, 16 is triggered.
  • a fan 8 in the region of the ventilation opening 6 may also be provided where it is not shown in the figures in order to support the air circulation for air exchange between elevator shaft 2 and staircase 4.
  • a smoke extraction opening 11 and / or a Nachströmö réelle 15 may also be realized in cases where it is not shown explicitly in the drawings. Further changes and adaptations of the particular design of the system are also conceivable and are at the discretion of the person skilled in the art.
