Definitions

  • the present invention relates to a system and also a method for ventilating and / or extracting smoke from an elevator shaft, in particular connected to separate fire compartments of a building located in different elevator levels, which is bounded by vertical shaft walls.
  • Elevator shafts and elevator cars must be ventilated and must be kept free of smoke in the event of a fire. If the detection of smoke and the subsequent need for smoke dissipation in the elevator shaft appear trivial, the recognition of a need for ventilation of the elevator shaft or the elevator car, according to the latest findings, depends on many parameters.
  • elevator shafts must usually be ventilated several times in the course of a day, depending on the use of the elevator system and the property, depending on the air quality, air temperature and elevator status.
  • the best-known emergency situation is an elevator malfunction involving people.
  • elevator shafts generally have an opening through which both ventilation of the Shaft and thus the elevator car, as well as in the event of a fire, smoke extraction from the shaft through natural ventilation, ie purely passive and without active ventilation, should be guaranteed.
  • This opening is generally located in the elevator shaft head or, if available, in an elevator machine room above and leads directly to the outside of the building envelope.
  • Such solutions are disclosed, for example, in the EP 1 890 956 B1 (with a purely passive, natural ventilation system) or in the DE 20 2006 012 724 U1 (There with a fan used to discharge smoke to the outside of the building in an otherwise purely passively operated exhaust air opening).
  • a system for ventilating a building is disclosed in which a stairwell or an elevator shaft is used as a vertical duct for ventilation.
  • ventilation openings in which fans can be arranged, are made in the boundary walls of the stairwell or elevator shaft on each floor.
  • the KR 100 902 635 B1 in this respect discloses a system with the features of the preamble of claim 1 and a method with the preamble of claim 10.
  • VOC volatile substances
  • elevator systems in commercial properties usually go to different elevator levels, which are located in different fire compartments.
  • the room air in front of the elevator shaft doors may not be used to feed uncontaminated fresh air into the elevator shaft, for example for safety reasons.
  • air from the lower floors of a property can only be used to ventilate the elevator shaft in the rarest of cases, as it is generally more strongly affected by carbon monoxide (CO), e.g. from an underground car park located below the residential or commercial areas in the building or from an in a basement area
  • CO carbon monoxide
  • the heating provided in the building, or by other gases such as radon and carbon dioxide (CO 2 ), which are heavier than air, is contaminated.
  • the room air in front of the elevator shaft doors must not be used to ventilate the elevator shaft for safety reasons.
  • the present invention is based on the assumption that when air is supplied to the elevator shaft, an independent supply air source is used for this purpose, or an exhaust air duct must be present in the elevator shaft. But even in the case of an existing ventilation duct via which fresh air from outside the property could be supplied to the elevator shaft, e.g. in the pit area, the elevator shaft ventilation with natural ventilation cannot be guaranteed.
  • Elevator shaft ventilation and smoke extraction systems which control the natural ventilation and smoke extraction of the elevator shaft via a window or a lamella flap in the shaft head or in the machine room are known from the prior art. Although such a system could be used in the elevator shaft of the property described, it cannot contribute to the safe operation of the elevator system or guarantee the safety of the elevator users due to the described lack of thermal in the elevator shaft.
  • the object of the present invention is to provide a system and also a method for ventilating and / or extracting smoke from an elevator shaft, which ensures safe and reliable ventilation of the elevator car even when the elevator shaft is connected to separate fire sections of a building in different elevator levels in the elevator shaft or the elevator shaft itself and also allow safe smoke extraction from the elevator shaft.
  • the fans arranged on opposite sides in the elevator shaft can in particular be arranged in the elevator shaft in the region of the shaft walls on opposite sides. But they can also be arranged in opposite positions on two car walls of the elevator car.
  • a mixed form is also conceivable in which fans are arranged both on the cabin walls and in the area of the shaft walls, with one fan group on one side of the elevator shaft both in an area of the shaft walls there and in an area of the cabin walls there combined number of fans is arranged, on the opposite side a fan group is formed by fans arranged there in the region of the shaft walls and the cabin walls.
  • the control is set up to control the fans for operation when a need for ventilation of the elevator car and / or the elevator shaft is detected in such a way that fans arranged on a first of the two sides convey air in the elevator shaft in an upward conveying direction (this can also be done, for example, by the above-mentioned first fan group), fans arranged on a second of the two sides in the elevator shaft (e.g. also by e.g.
  • the second fan group convey air in the elevator shaft in a downward conveying direction, and the control continues to do so set up to control the drive motor for the second closure element in such a way that this opens the exhaust air and smoke extraction duct, and to control the fans for operation in such a way that all fans arranged in the elevator shaft air in the elevator s shaft in a direction of conveyance in the same direction in the direction of a vertical or horizontal position in which the exhaust air and smoke extraction duct opens into the elevator shaft.
  • the volume of fresh air in the elevator shaft is sufficient to supply the elevator car with fresh air from this reservoir for a sufficiently long operating period.
  • the control can open the supply air duct by moving the closure element assigned to it and allow fresh air to flow in.
  • the exhaust air and smoke extraction duct is then expediently also opened in order to discharge stale air to the outside via it.
  • the fans can be operated in opposite directions, in particular as described above, in order to maintain air circulation in this case as well and to distribute fresh air supplied accordingly, to press air to be discharged out of the exhaust air and smoke extraction duct.
  • the fans are all operated in one direction of conveyance, i.e. the fans on one of the two sides rotate in the opposite direction of conveyance compared to the case of pure ventilation so to push the air with the smoke in one direction, namely in the direction of the exhaust air and smoke extraction duct that is then open, in order to divert the smoke there from the elevator shaft.
  • the supply air duct can also be opened in order to feed fresh and smoke-free air into the elevator shaft via it, to ensure there for fresh air, at least for a dilution of the smoke.
  • Opasite sides on which the fans according to the invention are arranged, mean here, for example, attachment positions on two opposite vertical shaft walls or on two opposite cabin walls.
  • positions on two adjacent shaft walls or cabin walls can also be “opposite one another” if these are, for example, along a diagonal of a shaft cross-section face each other. It is important here that the opposing positions are spaced apart from one another over a large distance of the cross section of the elevator shaft, so that a corresponding air flow (in particular an upward and a downward flow for ventilation) is generated on different sides of the elevator car in order to achieve the desired To achieve flow conditions (circulation or air delivery to the exhaust air and smoke extraction duct).
  • Probes arranged at various points can be used as the sensor or sensors. These can be, for example, air quality sensors for monitoring the air quality in the elevator car and / or in the elevator shaft, smoke detectors or temperature sensors in the elevator car and / or in the elevator shaft. However, sensors can also be used which detect movement of the elevator car or the presence of people in the car and / or in the elevator shaft. Switches or buttons for manually triggering ventilation and / or smoke extraction can also be understood as sensors in the context of this invention.
  • a plurality of fans can be arranged per side, this - in particular evenly - distributed over the height of the elevator shaft or over the height of the elevator car in order to achieve the air currents to be achieved (circulation in ventilation mode, directed removal in smoke extraction mode).
  • the fans on the opposite sides can, but need not, be arranged in pairs with at least one fan per side at the same height.
  • the supply air is brought into the elevator shaft from a lower position, and the exhaust air or smoke is discharged from the elevator shaft at an upper position. Therefore, the exhaust air and smoke extraction duct in particular can open vertically above the supply air duct into the elevator shaft.
  • the exhaust air and smoke extraction duct can be installed in a shaft head of the Elevator shaft or into a machine house arranged above the shaft head and located with the elevator shaft in a jointly ventilated volume.
  • the supply air duct can open into a shaft pit of the elevator shaft or in the area of a lowest elevator floor in the elevator shaft.
  • the first and / or the second closure element can in particular be formed by a lamella closure. Such a device can be opened and closed with a large opening cross-section while still saving space.
  • the figures each show a building section 1 with an elevator shaft 2 and an elevator car 3 that can be moved vertically in the latter.
  • a vertically or horizontally attached exhaust air and smoke extraction duct 5 opens, which connects the elevator shaft 2 to the outside with the ambient air located outside the building.
  • the exhaust air and smoke extraction duct 5 is equipped with a closure element 6, via which it can be closed, which in an open position releases the connection of the elevator shaft 2 to the outside, outside the building.
  • a supply air duct 7 is provided for the supply of non-contaminated fresh air from outside the building, which is also provided with a closure element 8 and can be closed by this.
  • One or both of the closure elements 6 and 8 can be lamellar flaps.
  • the variants shown are arranged on two opposite sides of the elevator shaft 2 on the respective shaft wall fans 9, 10 in different vertical height positions.
  • the fans 9 arranged on a first side and the fans 10 arranged on a second side opposite the first side are here each arranged in pairs at the same height.
  • a total of three fans 9 are provided on the first and three fans 10 on the second side,
  • One fan 9, 10 each in the area of the shaft head, one fan 9, 10 in the area of a lowermost elevator floor and one fan 9, 10 in a central section located in between.
  • the number of fans can be chosen freely, however, depends in particular on the dimensions, i.e. the overall height, but also the width and depth of the elevator shaft 2.
  • the fans 9, 10 are therefore essentially - according to the required number - over the entire length of the shaft mounted on two different shaft walls.
  • Figure 2 also shows a further fan 15, which can be arranged and operated in an air exchange opening of the elevator car 3, for example in the car ceiling, in order to convey an exchange of air between the interior of the elevator car 3 and the elevator shaft 2.
  • a further fan 15 which can be arranged and operated in an air exchange opening of the elevator car 3, for example in the car ceiling, in order to convey an exchange of air between the interior of the elevator car 3 and the elevator shaft 2.
  • the closure elements 6, 8 are motor-driven for opening and closing, and the associated drive motors (not shown), as well as the fans 9, 10, 13, 14, are connected to a controller (not shown).
  • sensors are provided that monitor various parameters, such as, in particular, the air quality of the air and / or the air temperature in the elevator car 3, the air quality of the air and / or the air temperature and / or the humidity in the elevator shaft 2 and smoke in the elevator shaft 2 can monitor. These sensors are also connected to the controller.
  • the ventilation, the air exchange or the smoke extraction of the elevator shaft 2 are initiated and operated by the controller via various processes:
  • Fig. 1 The procedure for ventilation is in Fig. 1 and also in Fig 2 shown.
  • ventilation of the elevator car 3 is recognized as necessary, e.g. in the event of an elevator malfunction with people trapped in the elevator car 3, it can be assumed that the elevator car 3 is naturally ventilated by air flowing past between the car and shaft walls.
  • a sufficient permanent exchange of air is created via the obligatory openings located in the floor and roof area of the elevator car 3. This can be done by one as in Fig. 2 shown fan 15, which also in a design variant according to Fig. 1 may be present, can also be promoted.
  • the fans 9, 10, 13, 14 mounted on opposite sides move the air in the elevator shaft 2 in opposite directions in the ventilation mode by the fans 9, or the fans 9, 13 of the first fan group (possibly also only the fans 13) convey the air in the elevator shaft 2 in a downward direction of flow and the fans 10, or the fans 10, 14 of the second Fan group (possibly also only the fans 14) convey the air in the elevator shaft 2 upwards.
  • the fans 9, 10, 13, 14 jointly build a circulating air circulation in the elevator shaft 2, indicated by the arrows in FIGS. 1 and 2, which then also ensures an exchange of air in the elevator car 3.
  • the elevator car is thus also above the circulating air 3 ventilated, wherein the of the elevator car 3-enriched CO 2 flowing air is mixed by circulation of the air in the elevator shaft.
  • the number of fans 9, 10, 13, 14, the distance between them, and the volume flow settings are made as a function of the dimensions of the elevator shaft 2 in order to obtain sufficient air circulation with the design achieved in this way.
  • opening of the closure elements 6 and 8 is dispensed with during this ventilation phase and the exhaust air and smoke extraction duct 5 and the supply air duct 7 are therefore kept closed until after the fans 9 and 10, or also or alternatively 13 and 13, have been put into operation 14, via air quality sensors attached in the elevator shaft 2 or on the outside of the elevator car 3, a limit value of the elevator shaft air that indicates an inadmissible air quality is reported in the control system.
  • the closure elements 6 and 8 open and, by removing used or even contaminated air through the exhaust air and smoke extraction duct 5 and supplying fresh air through the supply air duct 7, contribute to an improvement in the air quality in the elevator shaft 2 and thus also in the elevator car 3.
  • the elevator car 3 can be ventilated over a long period of time with supply air of appropriate air quality for the safety of the elevator users to ensure the well-being of the trapped people until they are liberated. If the air volume in the elevator car 3 is already used up after a very short time, the volume of the elevator shaft 2, intelligently used for car ventilation, generally provides a sufficiently large air reserve for prolonged ventilation of the elevator car 3 until trapped people are released. If the air in the elevator shaft 2 is insufficient, then, as described above, an exchange of air with the external environment is initiated by opening the closure elements 6, 8.
  • Fig. 3 The procedure for air exchange is in Fig. 3 , the one for smoke extraction is in Fig. 4 shown.
  • smoke 12 caused by a fire 11 is reported in the elevator shaft 2, for example by a smoke detector, it is by no means common for this smoke message to be passed on to the elevator control and this leads to an immediate evacuation trip to a smoke-free evacuation level.
  • Smoke 12 can easily be located on the lower levels in the elevator shaft 2 without passengers who climb into the elevator car 3 on the uppermost levels being able to perceive the smoke 12. For this reason, among other things, it is of the greatest importance to initiate an immediate smoke extraction from the elevator shaft 2 when smoke 12 is present in the elevator shaft 2. Particularly in modern, energetically optimized buildings, it cannot be ensured that this smoke extraction can be based on natural ventilation systems, or smoke can only be dissipated if sufficient uncontaminated supply air is provided.
  • the fans 9 are operated with opposite conveying directions, that is, they can be reversed in the conveying direction and controlled by the controller with regard to the setting of the conveying direction.
  • the air quality of the supply air which flows through the supply air duct 7 into the elevator shaft 2 when the closure element 8 is open, can be checked using a corresponding sensor system - both during smoke extraction and in ventilation or air exchange mode. If the air quality of this supply air does not correspond to the limit values left in the control, it can then be at the discretion of the control to move the closure element 8 into the closed position and to close the supply air duct 7 in order to prevent contaminated air from entering the elevator shaft 2 .
