In addition, the accessory room 30 in the present application may include a special evacuation stairs attached room provided in the platform or building which is a space between the elevator door 21 and the living room 60 for the elevator access. In particular, the accessory room 30 may include a fire door 34 formed in an area adjacent to the living room 60.

In the description of the embodiments of the present application, the case where the auxiliary room 30 to which the integrated smoke control system 1 is applied is mainly described as a landing area that is a space for elevator access, but is not limited thereto. The operation and function of the integrated smoke control system 1 may be equally applicable to the case where the accessory room 30 is a special evacuation stairs accessory room.

In addition, when the accessory room 30 is a platform for entering and exiting the elevator, the air supply air flow rate 20, which is an inflow passage of external air, may be a hoistway that is a moving passage of the elevator or a vertical duct separately provided in the platform.

On the contrary, when the accessory room 30 is a special evacuation stairs attached room provided in the building, the air supply air flow rate 20, which is an inflow passage of external air, may be a vertical duct provided in the special evacuation stairs attached room.

The lever type smoke elimination damper 1000 is installed in a predetermined region between the air supply air flow rate 20 and the accessory chamber 30, and supplies external air supplied to the air supply air flow rate 20 by the air supply fan 80. At least a portion may be opened to supply to or closed to block inflow of external air.

According to one embodiment of the present application, in the case of using the vertical duct provided in the auxiliary chamber 30 as the air supply air flow rate 20, a predetermined distance between the air supply air flow rate 20 and the auxiliary chamber 30, the lever-type ventilation damper 1000 is installed The region of may refer to a predetermined area that is open toward the auxiliary chamber 30 among the wall surfaces of the vertical duct corresponding to the boundary between the vertical duct and the auxiliary chamber 30.

According to another embodiment of the present application, when using the hoistway, which is the movement passage of the elevator, as the air supply airway 20, a predetermined area between the air supply airway 20 and the accessory chamber 30 in which the lever type ventilation damper 1000 is installed. May mean a predetermined area of the boundary wall of the hoistway and the accessory room 30 or the hoistway door 21.

In addition, according to the exemplary embodiment of the present application, the lever type damping damper 1000 may have unique address information assigned to each lever type damping damper 1000 installed in a building. In addition, the lever type damping damper 1000 may include a component that stores information such as a control unit, a memory, a communication unit, and communicates with an external device. In addition, each of the lever-type smoke control damper 1000 installed in the building may transmit the operation state information and the address information to the integrated control unit 40 when at least a part is opened or closed. Here, the address information may refer to data for identifying each of the plurality of lever type smoke elimination dampers 1000 installed in each floor regardless of the format or data type.

Further, according to one embodiment of the present application, the lever type damping damper 1000 may be a motorized damper (MD) including a motor and operating to open or close by driving the motor.

According to one embodiment of the present application, the lever-type smoke damper 1000 may be provided to adjust the amount of smoke air supplied to the smoke control area (accessory) by opening and closing operation according to the forward and backward movement of the flat plate (100). Therefore, the meaning of opening at least a part of the lever type smoke damper 1000 may vary according to the degree of forward and backward movement of the flat plate 100. It can mean that there is.

For example, the 100% opening of the lever type damping damper 1000 means that the flat plate 100 is advanced and supplied from the air supply air flow rate 20 introduced through the space separated from the damper frame 200 and the opening A. FIG. It may mean that the plate is advanced to the maximum so that the cross-sectional area through which the outside air passes through becomes maximum. On the contrary, when the lever type smoke damper 1000 is closed (in other words, 0% open), the flat plate 100 is damper frame so that external air does not flow into the auxiliary chamber 30 from the air supply airflow 20. Since it is not advanced from the 200 and the opening A, the gap between the flat plate 100, the damper frame 200, and the opening A may not exist. In addition, according to one embodiment of the present application, in order to properly adjust the wind speed, air volume, etc. of the outside air flowing into the accessory chamber 30, it is possible to adjust the degree of forward and backward of the flat plate 100 of the lever type damping damper 1000. .

In addition, according to one embodiment of the present application, the integrated control unit 40 is opened by the lever type smoke damper 1000, the plate 100 and the opening (A) or the damper frame 200 is formed to supply the outside air. The opening degree and the opening angle of the flat plate 100 may be controlled such that the spaced apart spaces between the planes are different with respect to each of four directions (up, down, left, and right directions). In exemplary embodiments, the integrated control unit 40 may control at least one of the plate rotation angle adjusting member 322 or the bar rotation angle adjusting member 340 included in the lever type damping damper 1000 to control the flat plate 100 and the opening ( A) or the spaced apart area between the damper frame 200 can be adjusted to be different for each of the four directions.

Specifically, through the control of at least one of the plate rotation angle adjusting member 322 or the bar rotation angle adjusting member 340, the lower end portion of the flat plate 100 is the opening (A) than the upper end of the flat plate 100 More spaced apart from the outside, the external air flowing downward into the ventilation zone 30 through the spaced space between the plate 100 and the opening A when the plate 100 is inclined to the whole / shape The amount of may be implemented to be greater than the amount of air introduced in the upward direction.

Here, it is understood that the integrated control unit 40 controls the opening degree of the lever-type smoke control damper 1000 to adjust at least one of the air flow rate and the wind speed of the external air supplied from the air supply air flow rate 20 to the accessory chamber 30. Can be.

With respect to the air volume of the outside air supplied to the accessory chamber 30, the integrated control unit 40 is pulled out of the smoke control area through the entrance door, the fire door 34, the window, the clearance of the lifting door 21, and the like of the accessory room 30. Opening of the lever-type smoke damper 1000 in consideration of at least one of the amount of air to be supplied or the amount of air to be further supplied to the accessory chamber 30 according to the opening and closing of the fire door 34 to be opened or closed in the evacuation of the occupants. You can control the degree.

In addition, in relation to the wind speed of the outside air supplied to the accessory chamber 30, the integrated control unit 40 may move to the accessory chamber 30 as the fire door 34 is temporarily opened and the air pressure of the accessory chamber 30 is temporarily lowered. The degree of opening of the lever type damping damper 1000 may be controlled in consideration of the flame-proof wind speed, which is the minimum air speed for blocking smoke from the fire chamber that may be introduced. For example, the smoke-proof wind speed may be determined in a range of 0.5 to 0.7 m / s with reference to national fire safety standards.

The integrated control unit 40 may receive a fire detection signal from the fire detector 70 and control the opening and closing of the lever type smoke damper 1000 on each floor of the building based on the fire detection signal.

7 is a view for explaining a state in which the lever-type smoke damper of the entire floor of the building is opened when the fire occurs by the integrated smoke control system according to an embodiment of the present application.

Referring to FIG. 7, when the fire detection signal is received from the fire detector 70, the integrated control unit 40 according to an embodiment of the present disclosure may control to open the lever type smoke suppression damper 1000 on the entire floor of a building. Can be.

In this regard, a gap between the landing door 21 for the landing and the auxiliary chamber 30 or the air supply airway 20 is allowed up to 10 mm, but is actually installed with a gap of about 5 mm. When the air flows from the air supply air freshness 20 to the accessory chamber 30 through the door gap or the air escapes from the air supply air chamber 20 to the air supply airflow 20 through the gap between each of the doors, Each time 1/100000 of the volume is supplied, a pressure of 1 Pa is raised. That is, even if air is supplied between the air supply airway 20 and the accessory chamber 30 in any direction, it can be seen as an open state in terms of pressure. Therefore, instead of the automatic differential pressure damper applied in the conventional ventilation system, a motor-type damper (MD) is installed in each floor of the lever type ventilation damper (1000), and the integrated control unit (40) automatically repeats opening and closing according to the fire occurrence signal. Compared to the case of using the differential pressure damper, it is possible to control to open the lever-type smoke damper 1000 of the entire floor in the event of a fire so that immediate and rapid dehumidification is achieved. Therefore, it is possible to promptly and consistently maintain the pressure difference in the ventilation zone and the indoor differential pressure (for example, 50 Pa) at the time of fire, so that the gas can be immediately pressed toward the fire door when the fire door is opened. In addition, due to the measurement and judgment of the differential pressure and control of the damper opening caused by the use of the automatic differential pressure damper, it is difficult to respond quickly to the pressure change of the accessory room when the fire door provided in the accessory room is opened, and between the landing door and the platform. In case of fire, it is difficult to accurately measure the pressure change caused by the amount of air leaked by the gap of the wall between the lift door and the hoistway, and the amount of air leaked by various gaps in the accessory room. This can be solved by keeping the motor-type lever type ventilation damper 1000 in the entire layer open.

In a conventional smoke control system, when a fire breaks out, a passenger may reach a panic phenomenon by checking a fire occurrence signal, and a fire door of a plurality of floors of the attached room 30 may be evacuated as the evacuation alarms of all floors simultaneously evacuate. 34) may be opened, but the automatic differential pressure damper is often opened only on the floor where the fire door 34 of the annex is opened, and thus, the dehumidification performance may be insufficient.

In this regard, according to one embodiment of the present application, when the fire detection signal is received from the fire detector 70, the integrated control unit 40, the lever-type smoke control of the entire floor, so that immediate and rapid dehumidification can be made in the attached room (30) The damper 1000 may be controlled to be opened to the maximum (ie, 100% open).

As another example, the integrated control unit 40 receives information associated with the fire detection signal and the fire occurrence intensity from the fire detector 70 to determine the driving ratio based on the fire occurrence intensity, and based on the determined driving ratio, the lever type smoke elimination. The degree of opening of the damper 1000 can be controlled. For example, when it is recognized that the fire occurrence intensity received by the integrated control unit 40 is an urgent situation exceeding a preset threshold intensity, the integrated control unit 40 sets the lever type smoke elimination damper 1000 at the maximum driving ratio. Can be controlled to open (at 100%). As another example, when the fire occurrence intensity received by the integrated control unit 40 is less than or equal to a predetermined threshold intensity, the integrated control unit 40 may control the lever type smoke elimination damper 1000 to be opened at a preset driving ratio. At this time, according to the embodiment, the predetermined threshold strength may be set to a plurality of values (levels) differentially, and accordingly, the driving ratio (opening ratio) of the lever type damping damper 1000 may also be changed to various values according to the situation. It can be implemented to have.

FIG. 8 is a view for explaining a state in which a fire generating layer and a lever type smoke damper of a predetermined upper and lower predetermined layers are opened when a fire occurs by the integrated dehumidifying system according to an exemplary embodiment of the present disclosure.

The lever type damping damper 1000 of the floor of the building may be controlled to open at a higher driving ratio than the lever type damping damper 1000 of the remaining floors of the building.

Here, the predetermined upper and lower predetermined layers for the fire generating layer may be determined based on information associated with the fire occurrence intensity received from the fire detector 70. For example, the number of upper and lower predetermined layers when the fire occurrence intensity is large may be determined to be larger than the number of upper and lower predetermined layers when the fire occurrence intensity is small.

In addition, according to one embodiment of the present application, the integrated control unit 40 controls the fire generating layer and the lever-type smoke removal damper 1000 of the predetermined upper and lower predetermined layers for the fire generating layer to open at least partially, and The lever type damping damper 1000 may be controlled to be closed.

As another example, the integrated control unit 40 controls to open the lever type smoke damper 1000 of all the floors in the building, but the lever type smoke damper 1000 of the predetermined upper and lower predetermined floors for the fire generating layer and the fire generating layer. The opening degree of the control unit may be controlled to be larger than the opening degree of the lever type damping damper 1000 of the remaining layers. That is, for example, the integrated control unit 40 controls the fire generating layer and the lever type dehumidifying damper 1000 of the predetermined upper and lower predetermined layers for the fire generating layer to be opened at a driving ratio of 80% and the lever type of the remaining layers. The ventilation damper 1000 may be controlled to open at a driving ratio of 40%.

As another example, the integrated control unit 40 first controls to open the lever-type smoke suppression damper 1000 of the fire generating layer, and then in consideration of information associated with additional fire conditions received from the fire detector 70, It may be controlled to open the lever-type ventilation damper 1000 of the predetermined upper and lower layers.

As another example, the integrated control unit 40 detects the address information and the operation state of the damper, and the lever-type smoke control damper 1000 installed on the floor where smoke or fire is generated or a lever installed on a predetermined number of floors adjacent to the floor. The type of smoke elimination damper 1000 may be controlled to open first.

In addition, the integrated control unit 40 may determine whether the respective Lever type damping dampers 1000 installed in the building are normally operated based on the operation state information and the address information received from the lever type damping damper 1000.

For example, the integrated control unit 40 transmits an open control signal or a closed control signal corresponding to a specific drive ratio to the lever type smoke suppression damper 1000 of each floor at a preset monitoring period, and correspondingly, the lever of each floor By receiving the operation state information and the address information from the type damping damper 1000, it is possible to determine whether the lever type damping damper 1000 of each floor is correctly opened or closed based on the control signal of the integrated control unit 40. . That is, the integrated ventilation system 1 according to an embodiment of the present application may provide a self-diagnosis function periodically checking whether there is an abnormality of the lever type ventilation damper 1000 based on address information and operation state information.

In addition, according to one embodiment of the present application, the integrated control unit 40, it is possible to switch to the manual operation mode so as to individually control the opening or closing of each of the lever-type smoke control damper 1000 installed on each floor of the building. You can do For example, the integrated control unit 40 or the manager control panel is connected and provided with signal connection lines and buttons for operating the opening and closing of each lever type ventilation damper 1000, and the button operation for each lever type ventilation damper 1000. Manual operation is possible via.

That is, when the integrated control unit 40 is switched to the manual operation mode, the manager or firefighter can differentially open or close each of the lever type smoke damper 1000 installed in each floor in consideration of various situations.

In addition, the integrated control unit 40 may control the driving force providing unit 400 to control the opening or closing of the lever type damping damper 1000.

In addition, according to an exemplary embodiment of the present application, the integrated control unit 40 may receive a detection result of at least one of the differential pressure sensor 31, the fire door sensor 32, or the smoke-free wind speed sensor 33. At this time, the integrated control unit 40, the differential pressure between the auxiliary room 30 and the living room 60 sensed by the differential pressure sensor 31, whether or not the opening or closing of the fire door 34 sensed by the fire door sensor 32 or the smoke-free wind speed The opening or closing of the lever type damping damper 1000 may be controlled based on at least one of the flame retardant wind speed values detected in the accessory chamber 30 by the sensor 33.

According to one embodiment of the present application, the integrated control unit 40 receives the differential pressure between the living room 300 and the accessory room 30 sensed by the differential pressure sensor 31 from the differential pressure sensor 31 to receive the accessory room 30 and the living room ( The opening degree of the lever type damping damper 1000 of the corresponding layer may be controlled so that the differential pressure between 60) is in the range of 40 Pa to 60 Pa.

In addition, according to the exemplary embodiment of the present application, the integrated control unit 40 receives whether the fire door 34 detected by the fire door sensor 32 is opened or closed, and according to whether the fire door 34 is opened or closed, the attached room 30 of the corresponding floor.
