In addition, although not shown in the drawing, the smoke control system 1000 may include a fire detector (not shown) that generates fire detection information in the building, such as whether a fire has occurred, a fire occurrence floor, a fire location, and fire intensity.

The outdoor air control device 100, the air supply blower 20, the overpressure discharge damper 30, and the fire detector (not shown) may communicate with each other through a network (not shown). A network (not shown) refers to a connection structure that allows information exchange between nodes such as terminals and servers. Examples of such networks (not shown) include the 3rd Generation Partnership Project (3GPP) network and LTE. (Long Term Evolution) network, 5G network, WIMAX (World Interoperability for Microwave Access) network, Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN ( Personal Area Network), wifi network, Bluetooth network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, etc. are included, but are not limited thereto.

The air supply duct 10 may be provided within the building to allow air supplied to the smoke control area within the building to flow. Exemplarily, referring to FIG. 1 , the air supply duct 10 may be a vertical duct (duct) formed through each floor of a building in the vertical direction. As another example, the air supply airway 10 may be designed to include a hoistway, which is a passage for an elevator installed in a building.

In other words, the air supply duct 10 is an inflow passage for air outside the building, and the supply air duct 10 in the air supply pressure smoke control system 1000 is a vertical duct provided for the hoistway or smoke control area, which is the moving passage of the elevator. It can be. In other words, the supply pressurized smoke control system 1000 according to an embodiment of the present application is provided in a building in which a vertical air supply wind 10, which is a vertical wind direction, is installed separately for the smoke control area 1, or a separate air supply wind 10 is installed separately for the smoke control area 1. It may be installed in buildings where vertical ventilation is not installed and the hoistway is used as an inflow passage for external air for smoke control.

The air supply blower 20 is connected to the air supply duct 10 and can supply air to the air supply duct 10. The air supply blower 20 is installed in a part of the air supply duct 10 and can supply air from outside the building into the air supply duct 10. For example, when the hoistway is used as the air supply 10, the air supply blower 20 may be installed at the bottom of the hoistway to supply air from outside the building into the hoistway. However, even in this case, the location where the air supply blower 20 is installed is not limited to the lower part of the hoistway, and may be installed in the upper or middle area of the air supply airway 10 depending on the embodiment.

Meanwhile, in the description of the embodiment of the present application, the decontamination area 1 is provided on each floor of the building and may be a space including an auxiliary room, a special evacuation staircase, and a platform as a waiting space for boarding an elevator. For example, the smoke control area (1) is an area within the building that is adjacent to the indoor (living room) of each floor and is separated from the indoor (living room) by a fire door (12), and has an air supply damper ( By installing 11), in the event of a fire, air is supplied from the air supply damper 11, and a smoke control process that prevents smoke from entering the room can be achieved.

The damper 30 for overpressure discharge may be installed at the end of the air supply windway 10 to prevent overpressure in the smoke control area 1. In this regard, when a fire occurs in a building equipped with the supply pressure smoke control system 1000 disclosed herein, the supply air blower 20 is set to a preset level according to a fire detection signal generated by a fire detector (not shown). It is operated to supply air to the supply air conduit (10) at the wind speed, and air is supplied to the ventilation area (1) by the air supply damper (11), which is connected to the supply air conduit (10) and branches off to each floor, thereby supplying air to the indoor (living room) area. ) forms a differential pressure for smoke prevention.

At this time, due to the air volume continuously supplied by the air supply blower (20), the fire door (12) between the smoke control area (1) and the living room is adjusted to the air supply windage (10) to the smoke control area (1) to the extent that the occupants cannot open it. When overpressure occurs, the overpressure discharge damper 30 installed at the end of the air supply airway 10 is opened and some of the air inside the air supply airway 10 is discharged to the outside of the air supply airway 10. It may be driven so that an appropriate level of differential pressure is formed inside the ventilation system 10 and in the ventilation area 1 of each floor.

The outdoor air control duct 40 may be provided adjacent to the overpressure discharge damper 30 so as to communicate with the above-described overpressure discharge damper 30 and the external space 2 of the building. For example, the outside air control duct 40 is installed so that the rear end (for example, the end at 9 o'clock in Figure 1) surrounds the overpressure discharge damper 30, and the front end (for example, in Figure 1) It may be provided as a duct structure that extends in the longitudinal direction toward the 3 o'clock end) and the internal space is formed along the front-to-back direction (for example, from 3 o'clock to 9 o'clock in FIG. 1, etc.).

The outside air control device 100 is a target space formed by the outside air control duct 40 between the above-described overpressure discharge damper 30 and the outside space 2 of the building, and is configured to control outside air from the outside space 2 of the building. It may be configured to allow selective inflow. In other words, in the description of the embodiment of the present application, 'target space' may refer to a space including at least a portion of the internal space of the duct 40 for controlling outside air.

In this regard, in the case of the conventional overpressure discharge damper 30, it is installed at the uppermost end of the air supply windway 10 in direct contact with the external space 2 of the building (for example, exposed to the roof of the building) However, if it is installed in a form that is directly affected by the air flow in the external space of the building, the overpressure formed in the air supply airway (10) or the smoke control area (1) is resolved. Even when the damper is opened to discharge the air inside the air supply windshield (10) to the external space (2), there is a limitation in that it cannot be operated properly in an environment where excessive wind pressure is formed in the external space (2) or where the wind blows strongly. .

In consideration of this, the supply pressure ventilation system 1000 disclosed herein is installed at the end of the supply air conduit 10 and includes an overpressure discharge damper 30 that prevents overpressure of the smoke control area 1 or the supply air conduit 10. ) is installed to selectively communicate with the air of the external space (2) of the building as needed, and the target space formed by the external air control duct (40) is communicated with the external space (2) or An outdoor air control device 100 including an opening/closing module 110 that opens or closes to disconnect may be provided in the target space. Meanwhile, referring to FIG. 1, the target space may be formed on the rooftop of a building where the air supply pressure smoke control system 1000 disclosed herein is installed, but is not limited thereto, and may be formed within the building according to an embodiment of the present application. It may be formed inside a specific layer.

Figure 2 is a schematic configuration diagram of an outdoor air control device according to an embodiment of the present application.

Referring to FIG. 2 , the outdoor air control device 100 may include an opening/closing module 110, a sensing module 120, a control module 130, and a communication module 140.

The opening/closing module 110 is a configuration that is opened or closed to communicate or disconnect the target space and the external space 2, for example, the target space including at least a portion of the internal space of the external air control duct 40 and the external space ( 2) It may include a door structure (for example, a window, etc.) interposed therebetween.

The sensing module 120 may acquire state information associated with at least one of the target space and the external space 2.

Specifically, according to an embodiment of the present application, the sensing module 120 can measure differential pressure information between the target space and the external space 2.

Additionally, according to another embodiment of the present application, the sensing module 120 may measure wind pressure information in an external space.

The control module 130 may control the opening/closing module 110 based on the state information acquired by the sensing module 120.

Specifically, according to an embodiment of the present application, the control module 130 may control the opening/closing module based on status information including differential pressure information between the target space and the external space 2. In a more specific example, the control module 130 determines that the pressure of the outside air in the external space 2 is greater than a preset critical pressure difference level compared to the pressure formed in the target space based on the differential pressure information measured by the sensing module 120. If it is determined that the door structure (not shown) of the opening and closing module 110 is determined to be relatively high, the possibility that the overpressure discharge damper 30 will not operate normally due to the high pressure of the outside air when the opening and closing module 110 is opened is determined. It can operate to close.

On the contrary, the control module 130 determines that the pressure of the outside air in the external space 2 is less than a preset critical pressure difference level compared to the pressure formed in the target space based on the differential pressure information measured by the sensing module 120 or the pressure difference formed in the target space. If the pressure is determined to be greater than the pressure of the outside air in the external space (2), it is determined that the outside air will have a minor effect on the operation of the damper 30 for overpressure discharge even if the opening and closing module 110 is opened, and the opening and closing module 110 is closed. It may operate to open a door structure (not shown).

Meanwhile, according to an embodiment of the present application, when opening the door structure (not shown), the control module 130 operates the door structure (not shown) based on the deviation between the measured pressure differential information and the preset critical pressure difference level. At least one of the opening level (eg, opening area, etc.) and opening time can be adjusted. For example, the control module 130 may adjust upward (adjust to increase) at least one of the opening level and the opening time of the door structure (not shown) as the pressure formed in the target space relatively greatly exceeds the pressure of the outside air. there is.

Additionally, according to another embodiment of the present application, the control module 130 may control the opening/closing module 110 based on status information including wind pressure information acquired by the sensing module 120.

Specifically, according to another embodiment of the present application, the control module 130 receives wind pressure information from the sensing module 120, and if the wind pressure information is greater than or equal to a preset threshold wind pressure, the external space 2 is opened when the opening/closing module 110 is opened. ) It is determined that there is a relatively high possibility that the overpressure discharge damper 30 will not operate normally due to the strong wind blowing in the air, and the door structure (not shown) of the opening/closing module 110 may be operated to close.

Here, the critical wind pressure is the opening area of the overpressure discharge damper 30, the minimum distance between the positions where the overpressure discharge damper 30 and the opening/closing module 110 are installed, the volume of the target space, and the size of the door structure (not shown). , the thickness of the door structure (not shown), the height of the target space (e.g., number of building floors, etc.), and the strength of the partition structure (e.g., wall structure, etc.) installed to separate the target space from the external space (2). , thickness, etc. may be preset to an appropriate value.

In addition, according to another embodiment of the present application, when opening the door structure (not shown), the control module 130 sets the opening level of the door structure (not shown) based on the difference between the measured wind pressure information and the preset critical wind pressure. At least one of (for example, opening area, etc.) and opening time can be adjusted. For example, the control module 130 adjusts upward (increases) at least one of the opening level and opening time of the door structure (not shown) as the wind pressure measured in the external space 2 is measured to be relatively lower than the preset critical wind pressure. adjustment) can be made.

The communication module 140 may receive reference information including at least one of fire detection information generated by a fire detector provided in the building and smoke prevention area information including whether a fire door provided for the smoke prevention area is opened or closed. .

Additionally, the control module 130 may control the opening/closing module 110 by considering the reference information received from the communication module 140. In this regard, according to an embodiment of the present application, the control module 130 opens or closes the door structure (not shown) of the opening/closing module 110, such as the above-described critical pressure difference level and critical wind pressure, based on the reference information. By adjusting the numerical range of the judgment criteria, not only the air flow between the target space where the outdoor air control device 100 is installed and the external space 2 is comprehensively considered, but also the situation inside the building where the fire occurs, The opening/closing module 110 can be controlled to communicate or disconnect the external space 2.

In addition, according to an embodiment of the present application, the control module 130 controls the measurement period for the sensing module 120 to obtain status information to be shortened as the scale of the fire increases, considering the reference information, so that the opening/closing module 110 By controlling whether to open or not and the level of openness in a relatively short cycle, active control that immediately reflects the fire situation within the building can be performed.

In addition, according to an embodiment of the present application, the control module 130 controls the measurement period for the sensing module 120 to acquire status information to become shorter as the fire door 12 is opened more frequently, thereby reducing the opening and closing module 110. By controlling the opening status and opening level in a relatively short cycle, active control that immediately reflects the evacuation situation of occupants in the building can be performed.

Hereinafter, the specific shape and function of the outdoor air control duct 40 will be described with reference to FIGS. 3 and 4.

Figures 3 and 4 are diagrams illustrating the shape of a duct for controlling outdoor air.

Referring to FIG. 3, according to an embodiment of the present application, an opening 41 through which external air from the external space 2 flows in may be formed on the lower surface of the external air control duct 40. In addition, referring to FIG. 3, the front section 42 of the outside air control duct 40 allows air inside the outside air control duct 40 or outside air flowing in from the external space 2 to easily flow through the opening 41. It can be provided in a sealed form to guide it.

Meanwhile, according to an embodiment of the present application, the specifications of the opening 41 formed in the outdoor air control duct 40 (for example, the length of the opening 41 in the front-back direction (L in FIG. 3) and the size orthogonal to the front-back direction The width (size of at least one of W in FIG. 3, etc.) takes into account the leakage area (leakage compartment area) associated with at least one of the overpressure discharge damper 30, the air supply damper 11, and the smoke control area 1. can be set.

In addition, referring to FIG. 4, according to another embodiment of the present application, the outer surface of the outdoor air control duct 40 has at least two surfaces along the surface direction orthogonal to the extension direction (in other words, front-to-back direction) of the outdoor air control duct 40. More openings 41 may be formed. More specifically, the outdoor air control duct 40 has a rectangular cross-section in the front-to-back direction, and an opening 41 is formed on at least one of the four sides including the upper, lower, left, and right sides. You can. For example, as shown in FIG. 4, openings 41 may be formed on all four sides of the outside air control duct 40, including the top, bottom, left side, and right side.

Hereinafter, the specific shape and function of the overpressure discharge damper 30 will be described with reference to FIGS. 5 and 6.

Figure 5 is a conceptual diagram showing the unit structure of a damper for overpressure discharge according to an embodiment of the present application.

Referring to FIG. 5, the unit structure 300 of the overpressure discharge damper 30 is installed on both sides of the inside of the case 301, which is the installation location, to be rotated (opened and closed) according to air pressure about the hinge 320 as an axis. However, the installation angle may be inclined to have an inclination range of, for example, 10° to 40°.

In this regard, the unit structure 300 of the damper 30 for overpressure discharge disclosed herein installs the damper wing 310 inclined to have an inclination of 10° to 40°, so that the hinge 34 is slightly rotated about the axis. There is an advantage in that the opening rate of the damper blade 310 can be rapidly increased.

On the other hand, the difference in the rotational action distance before and after opening the damper blade 310 (i.e., the distance (L1) from the hinge 320 to the bottom of the damper blade 310 before opening the damper blade 310 and the hinge 320 after opening) ) to the bottom of the damper wing 310 (L2)) is relatively small, so the change in the rotational force exerted by the self-weight of the wing on the hinge according to the opening of the damper wing 310 can be maintained without being large. .

Accordingly, the opening angle of the damper blade 310 responds sensitively to small changes in differential pressure, thereby increasing the effective opening rate and making it possible to control the differential pressure within an appropriate range.

In addition, the hinge 320 of the unit structure 300 in the present application is not at the top of the damper wing 310, but at a point of more than 1/2 of the total length of the horizontal portion excluding the bent portion 311 of the damper wing 310. By being positioned, the pressure acting on the bent portion 311 of the tip of the wing when the damper blade 310 is opened from a closed state becomes an absolute variable of the opening force, making it possible to numerically predict the opening force.

Meanwhile, the static pressure of the air (passing airflow) that applies pressure to one side of the damper blade 310 is lowered due to the traveling speed, and since only static pressure acts on the damper blade 310, the unit structure 300 is Because it does not directly respond to the pressure and responds to the static pressure inside the case 301, which is lower than that of the primary side, the damper wing 310 is not sufficiently opened and the internal pressure cannot be sufficiently discharged, so the internal differential pressure may be higher than the target value. there is.

Therefore, when the momentum of the airflow hitting the damper blade 310 is changed in the vertical direction by bending the end of the damper blade 310, the damper blade 310 is pushed up by the recoil, thereby improving the response accuracy of the damper blade 310. You can.

For this purpose, the lower bent portion 311 of the damper wing 310 is 60-100°, preferably formed in an arc shape with a bending angle of 70-90°, and the radius of the cross-sectional arc of the bent portion 311 is If is set to within 30% of the cross-sectional height of the space inside the casing, the open rate of the unit structure 300 can be secured at more than 70%.

Additionally, the unit structure 300 may include a counterweight 330 installed upward to maintain a 90° angle with the damper blade 310 on the upper part of the hinge 320. As the angle of the damper blade 310 approaches the horizontal, the counterweight 330 switches to a nearly vertical state and the horizontal distance from the hinge 320 decreases, so it can operate to offset the increase in rotational force of the damper blade about the axis. .

In addition, since the set differential pressure may be determined differently depending on the installation environment and installation intention of the supply pressure smoke control system 1000, in order to respond to different installation environments, the unit structure 300 is located at the upper center around the hinge 320. It may include a center of gravity adjustment means 340 installed on the damper wing 310.

Here, the center of gravity control means 340 can adjust the rotational force due to the self-weight of the damper blade 310 with respect to the hinge 320 to achieve equilibrium with the differential pressure acting on the damper blade 310 at an appropriate level.

Specifically, the center of gravity adjusting means 340 is installed on the lower surface of the damper wing 310 located at the upper part centered on the hinge 320, so that a pair of fixing brackets 341 and 342 are maintained at a certain interval so that they face each other. , an adjustment member 343 is installed penetrating the pair of fixing brackets 341 and 342, and between the pair of fixing brackets 341 and 342, a balance adjustment device moves forward or backward according to the rotation direction of the adjustment member 343. A weight 344 may be provided.

Therefore, when the balance adjustment weight 344 is installed and the position of the balance adjustment weight 344 is adjusted by turning the adjustment member 343, which is an adjustment screw, the rotational force of the damper blade 310 changes around the hinge 320, Accordingly, the rotational force balance centered on the hinge 320 changes, making it possible to respond to changes in differential pressure.

Figure 6 is a diagram illustrating an example of an overpressure discharge damper including a plurality of unit structures.

Referring to FIG. 6, the damper 30 for overpressure discharge includes at least one unit structure 300 described above (for example, as shown in FIG. 7, a plurality of unit structures 300 are aligned in the vertical direction. It may be a flap damper having at least one damper blade 310 installed to rotate according to the pressure of the air flowing in from the air supply wind 10.

However, the damper 30 for overpressure discharge of the air supply and pressure smoke control system 10 disclosed herein is not limited to the above-mentioned structure and shape, and according to the embodiment of the present application, a louver type damper, a flat type damper, etc. have been introduced in the past. Of course, it can be provided with dampers of various structures and shapes that have been developed or may be developed in the future.
