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) means a connection structure capable of exchanging information between nodes such as terminals and servers, and an example of such a network (not shown) includes a 3rd Generation Partnership Project (3GPP) network, 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 wind diagram 10 may be provided in the building so that air supplied to the ventilation area in the building flows. Illustratively, referring to FIG. 1 , the air supply air passage 10 may be a vertical wind passage (duct) formed through and crossing each floor of a building in a vertical direction. As another example, the air supply wind diagram 10 may be designed to include a hoistway, which is a moving passage of an elevator installed in a building.

In other words, the supply air flow rate 10 is an inflow passage of air outside the building, and the air supply air flow rate 10 in the air supply pressure ventilation system 1000 is a vertical duct provided for a hoistway or ventilation area, which is a movement passage of an elevator. can be That is, the pressurized air supply ventilation system 1000 according to an embodiment of the present application is provided in a building in which the air supply air flow 10, which is a vertical wind direction, is separately installed with respect to the control area 1, or is separately installed with respect to the control area 1 It may be provided in a building that uses a hoistway as an inflow passage for outside air for smoke control without installing a vertical air flow of .

The air supply blower 20 may be connected to the air supply air duct 10 to supply air to the air supply air duct 10 . The air supply blower 20 may be installed on a part of the air supply air duct 10 to supply air outside the building into the air supply air duct 10 . For example, when the hoistway is used as the air supply wind direction 10, the air supply blower 20 may be installed below 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 region of the air supply air passage 10 according to embodiments.

On the other hand, in the description of the embodiment of the present application, the control area 1 is provided for each floor of the building and may be a space including an auxiliary room, a special evacuation stairway, a platform that is a waiting space for boarding an elevator, and the like. For example, the ventilation area 1 is an area within a building adjacent to the indoors (living room) of each floor and separated from the indoors (living room) by a fire door 12, and an air supply damper connected to the air supply windway 10 ( 11) is installed, so that air is supplied from the air supply damper 11 in the event of a fire, and a smoke control process can be performed to prevent smoke from entering the room.

The overpressure discharge damper 30 may be installed at an end of the air supply airway 10 to prevent overpressure in the control zone 1 . In this regard, when a fire occurs in a building equipped with the supplied pressurized ventilation system 1000 disclosed herein, the supply air blower 20 operates at a preset location according to a fire detection signal generated by a fire detector (not shown). It is operated to supply air to the air supply air duct 10 by air volume, and air is supplied to the ventilation area 1 by the air supply damper 11 connected to the air supply air duct 10 and branched to each floor to provide indoor (living room) ) to form a differential pressure for smoke control.

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

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

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 outside air from the outside space 2 of the building It may be configured to be selectively introduced. In other words, in the description of the embodiment of the present application, 'target space' may refer to a space including at least a part of the inner 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 in direct contact with the external space 2 of the building at the uppermost end of the air supply airway 10 (eg, exposed to the roof of the building It is common to be installed as it is installed, etc.), but when it is installed in such a way that the effect of the air flow of the external space of the building is directly affected, the overpressure formed in the air supply airway (10) or the control area (1) is eliminated Even when the damper is opened to discharge the air inside the air supply airway (10) to the external space (2), there is a limit that it cannot be properly driven in an environment where excessive wind pressure is formed in the external space (2) or strong wind blows. .

In consideration of this, the pressurized air supply ventilation system 1000 disclosed herein is installed at the end of the air supply air duct 10 to prevent overpressure in the air supply area 1 or the air supply air duct 10. ) Installs an outdoor air control duct 40 to selectively communicate with the air of the external space 2 of the building as necessary, and communicates the target space formed by the outdoor air control duct 40 with the external space 2 or An outdoor air control device 100 having an opening/closing module 110 that is opened or closed to be disconnected may be provided with respect to the target space. Meanwhile, referring to FIG. 1 , the target space may be formed on the roof of a building in which the air-suppressed ventilation system 1000 disclosed herein is installed, but is not limited thereto, and according to an embodiment of the present application, the inside of the building It may be formed inside a specific layer.

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

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 and the external space including at least a part of the internal space of the duct 40 for controlling outside air ( 2) may include a door structure (eg, a window, etc.) interposed therebetween.

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

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

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

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

Specifically, according to one embodiment of the present application, the control module 130 may control the opening/closing module based on state information including pressure differential information between the target space and the external space 2 . More specifically, the control module 130 determines that the pressure of the external air in the external space 2 is greater than a predetermined threshold 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, it is determined that the damper 30 for overpressure discharge cannot be normally operated due to the high pressure of the outside air when the opening and closing module 110 is opened. can act to close

Conversely, the control module 130 determines that the pressure of the outside air in the external space 2 is less than a preset threshold pressure difference level compared to the pressure formed in the target space or formed in the target space based on the differential pressure information measured by the sensing module 120. If it is determined that the pressure is greater than the pressure of the outside air in the external space 2, even if the opening and closing module 110 is opened, it is determined that the outside air will have an insignificant effect on the driving of the damper 30 for discharging overpressure, and thus the opening and closing module 110 It can operate to open a door structure (not shown).

On the other hand, according to an embodiment of the present application, when the door structure (not shown) is opened, the control module 130 determines the level of the door structure (not shown) based on the difference between the measured differential pressure information and the preset threshold pressure difference level. At least one of an open level (eg, aperture area, etc.) and an open time may be adjusted. For example, the control module 130 may adjust (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.

Also, according to another embodiment of the present application, the control module 130 may control the opening/closing module 110 based on state 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 when the wind pressure information is greater than or equal to a preset threshold wind pressure, the external space (2) 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 normally operate due to strong wind blowing from, and the door structure (not shown) of the opening/closing module 110 may be operated to be closed.

Here, the critical wind pressure is the opening area of the overpressure discharge damper 30, the minimum distance between the locations 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 (eg, the number of floors of the building, etc.), the strength of the partition structure (eg, wall structure, etc.) installed to distinguish the target space from the external space 2 It may be preset to an appropriate value in consideration of , thickness, and the like.

In addition, according to another embodiment of the present application, when the control module 130 opens the door structure (not shown), the opening level of the door structure (not shown) is based on the deviation between the measured wind pressure information and a preset threshold wind pressure. (eg, opening area, etc.) and opening time may be adjusted. For example, the control module 130 adjusts (increases) at least one of the opening level and the opening time of the door structure (not shown) as the wind pressure measured in the external space 2 is relatively low compared to a preset critical wind pressure. can be adjusted).

The communication module 140 may receive reference information including at least one of fire detection information generated by a fire detector provided in a building and control area information including whether or not a fire door provided for the control area is opened or closed. .

In addition, the control module 130 may control the opening/closing module 110 in consideration of the reference information received from the communication module 140 . In this regard, according to one embodiment of the present application, the control module 130 opens or closes the door structure (not shown) of the opening and closing module 110, such as the threshold pressure difference level and the threshold wind pressure, based on the reference information. By adjusting the numerical range of the judgment standard for the outside air control device 100 is installed, the target space and The opening/closing module 110 may 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 state information to be shortened as the scale of the fire increases in consideration of the reference information, so that the opening and closing module 110 It is possible to perform active control that immediately reflects the fire situation in the building by allowing control of whether or not to open and the level of opening to be performed at a relatively short cycle.

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 state information to be shortened as the opening of the fire door 12 occurs more frequently, so that the opening/closing module 110 It is possible to perform active control that immediately reflects the evacuation situation of occupants in the building by controlling whether or not to open and the level of opening of the building at a relatively short cycle.

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

3 and 4 are diagrams showing the shape of a duct for controlling outside air by way of example.

Referring to FIG. 3 , according to one embodiment of the present application, an opening 41 through which outside air from the external space 2 flows may be formed on the lower surface of the duct 40 for controlling outside air. In addition, referring to FIG. 3, the front end surface 42 of the duct 40 for controlling outside air flows easily through the opening 41 of the air inside the duct 40 for controlling outside air or the outside air introduced from the external space 2. It may be provided in a closed form to guide it.

On the other hand, according to an embodiment of the present application, the standard of the opening 41 formed in the duct 40 for controlling outside air (for example, the length of the opening 41 in the front-back direction (L in FIG. 3) and the front-back direction orthogonal to the The width (such as the size of at least one of W in FIG. 3) is determined in consideration of the leakage area (leakage compartment area) associated with at least one of the overpressure discharge damper 30, the air supply damper 11, and the control area 1 can be set.

In addition, referring to FIG. 4 , according to another embodiment of the present application, on the outer surface of the duct 40 for controlling outside air, there are at least two or more two surfaces perpendicular to the extending direction (in other words, the front-back direction) of the duct 40 for controlling outside air. More than one opening 41 may be formed. More specifically, the duct 40 for controlling outdoor air is provided with a rectangular cross-section along the front-back direction, and the opening 41 is formed on at least one of the four surfaces including the upper, lower, left and right surfaces. can Illustratively, as shown in FIG. 4 , openings 41 may be respectively formed on all four surfaces of the duct 40 for controlling outside air, including the upper, lower, left, and right sides.

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

5 is a conceptual diagram illustrating a unit structure of a damper for overpressure discharge according to an embodiment of the present disclosure.

Referring to FIG. 5, the unit structure 300 of the damper 30 for overpressure discharge is installed to rotate (open and close) according to the air pressure around the hinge 320 on both inner sides of the case 301, which is the installation location However, the installation angle may be installed 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 is installed with the damper wing 310 inclined to have an inclination of 10 ° to 40 ° by slightly rotating the hinge 34 as an axis. There is also an advantage in that the opening rate of the damper wing 310 can be rapidly increased.

On the other hand, the difference in the rotational action distance before and after the opening of the damper wing 310 (ie, the distance L1 from the hinge 320 before the opening of the damper wing 310 to the lower end of the damper wing 310 and the hinge 320 after opening ) to the lower end of the damper wing 310, the difference (W) of the distance L2 is relatively small, so that the change in the rotational force of the wing's own weight acting on the hinge is not large as the damper wing 310 is opened. .

Accordingly, the opening angle of the damper blade 310 responds sensitively even to a small change in differential pressure, thereby increasing an effective opening rate and adjusting the differential pressure within an appropriate range.

In addition, the hinge 320 of the unit structure 300 in the present application is located at 1/2 or more of the entire length of the horizontal portion excluding the bent portion 311 of the damper wing 310, not the upper end of the damper wing 310. When the damper wing 310 is opened from the closed state, the pressure acting on the bent portion 311 of the tip of the wing becomes an absolute variable of the opening force, thereby enabling numerical prediction of the opening force.

On the other hand, the static pressure of the air (passing air flow) applying pressure to one side of the damper blade 310 is lowered due to the traveling speed, and since only the static pressure acts on the damper blade 310, the unit structure 300 is on the primary side Since the damper wing 310 is not sufficiently opened, the internal differential pressure cannot be sufficiently discharged, so that the internal differential pressure can be higher than the target value. there is.

Therefore, when the momentum of the air current impinging on 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 reaction, thereby improving the response accuracy of the damper blade 310. can

To this end, the lower bent part 311 of the damper wing 310 is 60-100 °, preferably may be formed in an arc shape with a bending angle of 70-90 °, and the radius of the cross-sectional arc of the bent part 311 If is set within 30% of the cross-sectional height of the inner space of the casing, an open rate of the unit structure 300 of 70% or more can be secured.

In addition, the unit structure 300 may include a counterweight 330 installed upward to maintain a 90° angle with the damper wing 310 above the hinge 320 . The balance weight 330 is converted to a state close to vertical as the angle of the damper wing 310 approaches the horizontal, so that the horizontal distance with the hinge 320 decreases, so it can operate to offset the increase in the rotational force of the damper wing with respect to the axis. .

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

Here, the center of gravity adjusting means 340 can balance the differential pressure acting on the damper blade 310 at an appropriate level by adjusting the rotational force of the damper blade 310 relative to the hinge 320 due to its own weight.

Specifically, the center of gravity control means 340 is installed so that a pair of fixing brackets 341 and 342 face each other at a predetermined interval on the lower surface of the damper wing 310 located at the upper portion around the hinge 320 The pair of fixing brackets 341 and 342 have an adjusting member 343 installed through them, and between the pair of fixing brackets 341 and 342, balance control moving forward or backward according to the direction of rotation of the adjusting member 343 A weight 344 may be provided.

Therefore, when the balance control weight 344 is installed and the position of the balance control weight 344 is adjusted by turning the adjusting screw 343, the rotational force of the damper wing 310 is changed around the hinge 320, Accordingly, since the rotational force balance centered on the hinge 320 is changed, it is possible to respond to the differential pressure change.

6 is a view showing an example of a damper for overpressure discharge including a plurality of unit structures.

Referring to FIG. 6, the overpressure discharge damper 30 includes at least one unit structure 300 described above (for example, as shown in FIG. 7, a plurality of unit structures 300 are arranged side by side in the vertical direction). It may be a flap damper having at least one damper wing 310 installed to be rotated according to the pressure of the air introduced from the air supply airway 10.

However, the overpressure discharge damper 30 of the supplied air ventilation system 10 disclosed herein is not limited to the above-described structure and shape, and according to the embodiment of the present application, conventionally introduced louver-type dampers, plate-type dampers, etc. Of course, it can be provided with dampers of various structures and shapes that have been or can be developed in the future.
