    APPLY FOR PRESSURE OF THE INTERIOR SPACE IN A BUILDING, EX. THE STEP RISE IN A FLOOR HOUSE, BY A FIRE SCENARIO
    The object of the present invention is a system for pressurizing the interior space of a building, e.g. the staircase in a storey house, by a fire scenario and for the removal of smoke from the relevant room, where the plant includes a pressure setting fan and one or more open and closed shutters connected to the outdoor air for smoke removal.
    The basic task of smoke control in a fire scenario is to keep the starting materials free of smoke and to ensure unobstructed evacuation of people from the building. At floor houses, pressurization of the staircase, hallway and elevator shaft has become commonplace, in which case a large amount of clean air is conducted to these rooms by a fire scenario. The rooms are kept under pressure relative to their surroundings. For this, a fan with which the pressure setting is obtained is needed. In this way, the exit means are kept free of smoke and evacuation of people from the building is ensured. In addition to improving evacuation security, the pressurization results in significantly better working conditions for those performing rescue work in a fire scenario.
    In addition to this, the staircase is provided with smoke extraction, which is usually located e.g. in the upper part of the staircase and through which the fire gases are vented to the outdoor air. An externally opened shut-off valve without a fan or as an additional component of a fan is most often used in smoke extraction. The fire corps typically starts the smoke extraction from a separate switch after arriving at the fire site.
    The operating principle is that after a fire breaks out in an apartment, the fire detector in this apartment sends a signal to the pressure setting fan which starts 2 2DK 2010 00164 U3. The pressure setting fan is typically located e.g. in the lower part of the staircase. Overpressure is generated in the staircase as the fan operates, which prevents the smoke from the burning apartment from escaping to the staircase as long as most doors are closed. At this stage, the smoke extraction and ventilation are usually started when the fire corps arrives at the site.
    A modern plant thus requires a separate fan and a smoke extractor shut-off valve. The purpose of the production is to obtain a new and better device than before. The plant according to the invention is new in that the plant comprises a device connected to the outdoor air, the device comprising an air duct, a fan located in the air duct, and one or more open and closed shut-off valves between the air duct and the outdoor air.
    A preferred embodiment of the plant according to the invention is new in that the rotational direction of the fan can be changed, in which case the first rotational direction is intended to pressurize the staircase and the second rotational direction is intended to increase the smoke extraction via the opened shut-off valves.
    Another preferred embodiment of the system according to the invention is new in that there are two open and closed hinged shut-off valves with which an arm is connected for moving them and in that the apparatus comprises linear motors by means of which the arms are arranged for to move and the shutters are arranged to open and close by means of them.
    Some of the benefits of the generation, which can be mentioned, are that it improves personal safety during a fire in an evacuation situation and in the apartments which are located in the same staircase as the burning camp 3 3DK 2010 00164 U3 equality. In the production, the design and implementation of pressure suction and smoke extraction are facilitated in comparison with existing solutions. The device used in the plant according to the invention is compact.
    The invention will now be described in more detail by means of a preferred embodiment with reference to the accompanying drawing, in which
    FIG. 1 shows a side view of a device according to the manufacture with the shut-off valves opened.
    FIG. 2 shows a section A-A of FIG. First
    Thus, the drawing shows a device 1 according to the production for pressurizing the interior space of a building, e.g. the staircase, and for the removal of smoke from the relevant room. Both functions are integrated in the same device. The device is located e.g. in the upper part of the staircase, preferably on its roof, so that it communicates with the outdoor air. The device is thus usually located on the roof of the building. The device comprises walls 3 bordering e.g. a substantially rectangularly shaped air duct 4 within them. The upper part of the duct is in a normal situation closed by the shutters 2, but the drawing shows a situation, generally a fire scenario, where the shutters are opened. The shutter valves 2 are hinged at their outer edges to the wall 3. The shutter valves are provided with arms 5, which are moved backwards and forwards longitudinally by linear motors 6 for opening and closing the shutter valves. The air duct 4 is protected at its lower end by a protective net 7.
    An axial fan 8, the direction of rotation of which can be changed, is installed in the channel 4. The construction of the axial fan is not described in detail in this connection, because it may be any known solution suitable for the purpose. . The plant according to the production and the device 1 used in it, e.g. as follows:
    A fire breaks out in an apartment, in which case the fire detector in the apartment gives a signal to the device 1 according to the production. In this case, the shutter valves 2 of the device open and the axial fan 8 starts and blows clean outdoor air into the stairway. In this case, an excess pressure (e.g., approximately 50 Pa) is generated in the staircase, which prevents the entry of fire gases into the staircase. Of course, the overpressure begins to decrease when a door is opened, e.g. when residents leave their apartments through the lower door of the stairwell. In this phase, when the smoke eventually begins to enter the staircase, the firefighters can begin the removal of smoke with the device of the generation. This takes place from a separate switch by which the direction of rotation of the axial fan 8 is changed and the fire gases begin to enter the outdoor air via the channel 4 of the device 1.
    It will be apparent to one skilled in the art that the production is not limited to the embodiments set forth above, but that it may be varied within the scope of the subsequent utility model requirements. For example, the cross-sectional shape of the channel 4 of the device 1 may be different from a rectangle. There are one or more blinds 2 and their shape may vary. Likewise, their opening and closing mechanism may also be different from that set forth above.
