Description

Smart smoke control system based on inverter blower {SMART SMOKE CONTROLLING SYSTEM BASED ON INVERTER AIR BLOWER}

The present invention relates to a smart smoke control system based on an inverter blower. More specifically, in the event of a fire in a building, the operation of the inverter blower is controlled based on the differential pressure generated between the smoke control area and the interior to control the operation of the inverter blower to control the flow of external air supplied to the differential pressure damper. This is about a smart smoke control system based on an inverter blower that can appropriately control the blowing volume.

Generally, in the event of a fire in a building, the space in front of the elevator or in front of the staircase is defined as a smoke control area, and the building is equipped with a smoke control device or smoke control equipment to prevent smoke or harmful gases generated inside the building from entering the smoke control area. Therefore, casualties due to fire outbreaks can be greatly reduced because the building's smoke control system or smoke control equipment allows occupants to safely evacuate out of the building through evacuation stairs or elevators.

Representative smoke control devices installed in the smoke control area of a building include a differential pressure damper installed in each floor of the building to communicate with the vertical wind that guides outside air along the vertical direction of the building, and a smoke control system that directs the outside air of the building to each floor. Includes a blower installed on a vertical wind pipe to supply the area.

The blower described above must be selected with a designed air volume to provide smoke control performance corresponding to the number of floors and structure of the building. In particular, it is desirable that the designed air volume of the blower sufficiently secures the following three smoke control performances required in various situations when a fire occurs in a building.

In reality, typical smoke control devices installed in buildings above a certain height must be designed to meet the three design standard requirements or smoke control performance requirements below.

1) The differential pressure between the production area and indoors must be maintained within the required pressure range (e.g., 40 to 60 Pa range).

2) If at least one of the doors to the smoke control area is open, the smoke retardant wind speed required for the open door in the smoke control area (e.g., 0.7 m/s or more) must be secured.

3) At the same time as 2), maintain the differential pressure (e.g., differential pressure corresponding to 70% of 40~60Pa) required in the smoke control area of other floors (unopened floors) where the doors are not open.

In other words, the differential pressure dampers on each floor are normally closed, but in the event of a fire, they are opened at a preset opening ratio and the differential pressure between the smoke prevention area and the interior is within the required pressure range (for example, the differential pressure between the smoke smoke zone and the interior is within the range of 40 to 60 Pa). The pressure is maintained high, but when the door connected to the smoke control area of the fire floor is opened, the opening rate of the differential pressure damper is further increased to allow evacuation of occupants from the fire floor, thereby reducing the smoke-retardant wind speed required for the indoor access door in the smoke control area (e.g. , 0.7 m/s or more).

However, existing smoke control devices may have performance problems that prevent them from smoothly meeting the three requirements above in various situations when a fire occurs. In particular, if the designed air volume of the blower is too small, the amount of air supplied from the differential pressure damper to the smoke control area will be insufficient in the event of a fire in the building, or conversely, if the design air volume of the blower is too high, the amount of air supplied from the differential pressure damper to the smoke control area will be insufficient in the event of a fire in the building. This can be too much.

In other words, if the air supply from the differential pressure damper increases excessively in a situation where all doors to the smoke control area on each floor are closed, the pressure in the smoke control area increases excessively, resulting in a situation where the occupants cannot or find it difficult to open the door due to the overpressure in the smoke control area. There is a problem that arises. In addition, if the air supply from the differential pressure damper is insufficient in a situation where all doors to the smoke prevention area on each floor are closed, the pressure in the smoke prevention area is greatly reduced, so the differential pressure between the smoke prevention area and the interior becomes smaller, allowing indoor fire smoke to enter the smoke smoke zone through the doors. There is a problem with the flow.

In order to improve the above problems, various technologies for smoke control systems employing inverter blowers have recently been continuously researched and developed to meet the smoke control performance requirements of smoke control equipment. For example, related prior art documents include Korea Patent Publication No. 10-2015-0139353 (title of the invention: air supply damper, publication date: 2015.12.11) and Korea Patent Publication No. 10-2016-0038141 (title of the invention: There is a non-directional differential pressure damper (publication date: 2016.04.07).

In addition, in an embodiment of the present invention, when a fire occurs in a building, the fire floor and the non-fire floor are determined and then the opening ratios of the differential pressure dampers installed on the fire floor and the non-fire floor are controlled differently from each other to control the air supply portion from the non-fire floor. We provide a smart smoke control system based on an inverter blower that can prevent waste of energy.

According to an embodiment of the present invention, a differential pressure damper is installed in each floor of the building to control the pressure of the smoke control area by supplying external air to the smoke control area when a fire occurs, and a differential pressure damper to supply outside air to the differential pressure dampers. It provides a smart smoke control system based on an inverter blower, including an inverter blower and a blower control panel that receives a differential pressure signal representing the pressure difference between the smoke control area and the indoor space and controls the blowing volume of the inverter blower based on this.

Preferably, the smart smoke control system based on an inverter blower according to an embodiment of the present invention is installed in at least one smoke control area among the smoke control areas on each floor of the building and corresponds to the measured differential pressure between the at least one smoke control area and the indoor.

The blower's drive motor can be controlled to slow down to a rotation speed lower than the normal rotation speed.

When the differential pressure in the manufacturing area and the indoor area on the floor of the building where the first differential pressure signal board is located and the floor of the building where the second differential pressure signal board is located falls below a preset differential pressure range, the first differential pressure signal Among the board and the second differential pressure signal board, the differential pressure signal board that detects this first may transmit the differential pressure signal to the blower control panel, and the blower control panel that receives the differential pressure signal may be used to increase the blowing volume of the inverter blower. The driving motor of the inverter blower can be controlled to accelerate at a rotation speed higher than the normal rotation speed.

Meanwhile, the blower control panel may control the drive motor of the inverter blower to maintain the normal rotation speed again when the differential pressure between the manufacturing area and the indoor re-enters the preset differential pressure range.

Preferably, the blower control panel includes a differential pressure-current conversion unit for converting the differential pressure signal received from the differential pressure signal board into a current for controlling the driving motor of the inverter blower in an inverter method, and the differential pressure-current conversion unit. It may include an inverter motor control unit that controls the driving motor of the inverter blower according to the control current received from the unit.

Preferably, the smart smoke control system based on an inverter blower according to an embodiment of the present invention may further include a fire detector provided on each floor of the building to detect an indoor fire on each floor connected to the smoke control zones.

The differential pressure damper may include an air supply unit for adjusting the supply amount of external air according to the opening ratio. At this time, the differential pressure damper can determine the fire layer and the non-fire layer according to the presence or absence of a fire detection signal received from the fire detector in conjunction with the fire detector, and the opening ratio of the air supply portion in the fire layer and the non-fire layer. The opening ratio of the air supply part can be controlled differently.

Preferably, the differential pressure damper operates so that the air supply unit opens within a preset limited opening ratio when a fire occurs in the building, but in the fire floor where a fire detection signal is received from the fire detector, the air supply unit operates according to the limited opening ratio. Restrictions can be lifted.

Here, the differential pressure damper disposed on the non-fire floor may be operated to adjust the opening rate of the air supply portion within the limited opening rate regardless of whether the indoor door of the non-fire floor is opened or closed.

In addition, the differential pressure damper disposed in the fire floor is operated to adjust the opening rate of the air supply portion within the limit opening rate when the indoor door of the fire floor is closed, but the indoor door of the fire floor is open. In this case, the opening ratio of the air supply portion may be operated to adjust at a maximum opening ratio greater than the limited opening ratio.

Preferably, the differential pressure damper is operated in a differential pressure mode to maintain the differential pressure between the smoke control zone and the indoor within a preset differential pressure range by adjusting the opening rate of the air supply unit within the limited opening rate when the indoor door is closed. You can. The differential pressure damper disposed on the fire floor may be operated in a smoke prevention wind speed mode to generate a preset wind speed from the smoke control zone toward the indoor by adjusting the opening rate of the air supply part at the maximum opening rate when the indoor door is opened. You can.

Preferably, the differential pressure damper includes a differential pressure measuring unit provided to measure the differential pressure between the air supply unit, the smoke control area, and the indoor, and an opening ratio of the air supply unit according to signals received from the fire detector and the differential pressure measuring unit. May include a damper controller.

At this time, the damper controller can determine a fire floor and a non-fire floor depending on the presence or absence of a fire detection signal from the fire detector.

The damper controller may be provided with an aperture ratio control unit for an administrator to set or change the limited aperture ratio in the field when installing the differential pressure damper.

Preferably, in the differential pressure damper, the setting of the limiting opening ratio of the air supply portion may be implemented in either a hardware method or a software method. For example, the differential pressure damper may measure the total operating time required from the closed state to the fully opened state of the air supply unit, and based on the total operating time, the limited operating time corresponding to the limited opening ratio may be used to measure the total operating time. A program that limits the operation of the air supply may be further included.

The smart smoke control system based on an inverter blower according to an embodiment of the present invention can secure evacuation safety for occupants by preventing indoor fire smoke from flowing into the smoke control area due to external air supplied by the differential pressure damper when a fire occurs in the building. In particular, the amount of air supplied to the differential pressure damper can be more effectively controlled by increasing or decreasing the blowing volume of the inverter blower that supplies external air to the differential pressure damper based on the differential pressure in the smoke control area and indoors.

In addition, the smart smoke control system based on an inverter blower according to an embodiment of the present invention effectively prevents indoor fire smoke from flowing into the smoke control area when a building fire occurs, thereby reducing the risk of casualties to occupants due to fire smoke flowing into the smoke control area. This can be reliably prevented, and the problem of occupants being unable to open the indoor door in the direction of evacuation or finding it difficult to open the indoor door in the evacuation direction due to the differential pressure in the smoke control area and indoors increasing above the preset differential pressure can be resolved in advance.

In addition, the smart smoke control system based on an inverter blower according to an embodiment of the present invention is a structure that increases or decreases the operation of the inverter blower in the event of a fire in a building based on the differential pressure between the smoke control area and the interior, so that it is controlled by the differential pressure damper on each floor through vertical wind. By appropriately adjusting the blowing volume of the supplied outside air, the problem of abnormally increasing or decreasing the air supply volume of the differential pressure damper on each floor can be resolved, and the performance of the differential pressure damper can be optimized according to the fire situation of the building.

In addition, the smart smoke control system based on an inverter blower according to an embodiment of the present invention places differential pressure signal boards on the high and low floors of the building when a fire occurs in the building, so that the blower control panel operates the inverter blower through the differential pressure signal from the differential pressure signal board. Since it is a structure that controls the blowing volume, the blower control panel can easily control the operation of the inverter blower using differential pressure signals transmitted from several differential pressure signal boards, and in the event of a fire in the building, the operation of the inverter blower can be quickly and appropriately accelerated or accelerated. By reducing the speed, you can actively respond to the problem of insufficient or excessive air supply to the differential pressure damper on each floor.

In addition, the smart smoke control system based on an inverter blower according to an embodiment of the present invention determines the fire floor and the non-fire floor using the detection results of the fire detector, and then determines the fire floor and the non-fire floor depending on whether the indoor door is opened or closed. Since it is a structure that limits or releases the opening rate of the differential pressure dampers placed in the building, the smoke control performance of the differential pressure dampers for various fire situations can be stably secured in the event of a fire in the building, and the differential pressure dampers can be safely controlled in the fire floor and non-fire floor. By controlling the opening ratio of the base differently, it is possible to stably secure the smoke control performance of the differential pressure damper in the fire layer and prevent waste of air supply from the differential pressure damper in the non-fire layer.

In addition, in the smart smoke control system based on an inverter blower according to an embodiment of the present invention, when a fire occurs in a building and the indoor door of the fire floor is opened, the differential pressure damper installed in the smoke control area of the fire floor increases the opening rate of the air supply part to the maximum. It is possible to create sufficient smoke control wind speed in the smoke control area of the fire floor, and the differential pressure damper of the non-fire floor constantly limits the opening rate of the air supply section regardless of whether the indoor door of the relevant floor is opened or closed, so that the smoke control area of the non-fire floor A differential pressure of an appropriate size can be formed. Therefore, in this embodiment, even if the indoor door is opened in the non-fire floor, the opening ratio of the air supply part of the differential pressure damper does not increase, so the problem of the differential pressure damper installed in the non-fire floor abnormally supercharging external air to the smoke prevention area can be prevented. Accordingly, the blowing volume of external air supplied to the differential pressure damper of the fire floor by the inverter blower can be secured.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings. However, the present invention is not limited or limited by the examples. The same reference numerals in each drawing indicate the same members.

1 and 2 are diagrams schematically showing a smart smoke control system 100 based on an inverter blower 120 according to an embodiment of the present invention. FIG. 3 is a diagram schematically showing main parts of the smart smoke control system 100 shown in FIGS. 1 and 2, and FIG. 4 schematically shows the control configuration of the smart smoke control system 100 shown in FIGS. 1 to 3. It is a drawing.

1 to 4, the smart smoke control system 100 based on the inverter blower 120 according to an embodiment of the present invention includes a differential pressure damper 110, an inverter blower 120, a blower control panel 130, Includes a differential pressure signal board 140 and a fire detector 150.

In this embodiment, the smart smoke control system 100 is limited to being installed in a building 10 of 20 floors or less, but is not limited thereto and can also be applied to buildings exceeding 20 floors. An indoor 30 and a smoke-free zone 20 may be provided on each floor of the building 10, respectively. The manufacturing area 20 can be connected to the indoor space 30 through the indoor door 32, can be connected to the evacuation staircase 22 through the stairway door 23, and can also be connected to the elevator room through the elevator door. . Hereinafter, in this embodiment, for convenience of explanation of the smart smoke control system 100, the elevator door and elevator room are omitted, but only the indoor door 32 is opened and closed.

The smoke prevention area 20 as described above is an area where the inflow of fire smoke generated indoors 30 is blocked when a fire occurs in the building 10. The smoke control area 20 may include an auxiliary room corresponding to the front room formed between the indoor entrance door 32 and the fire door.

Additionally, the building 10 may be provided with a vertical wind vent 40 to supply outside air A to the smoke control area 20 on each floor. The vertical windshield 40 as described above serves as a passageway that guides the outside air A sucked in from the outside of the building 10 to the smoke control areas 20 located on each floor.

When a fire occurs in the building 10, outside air A may be supplied to the differential pressure dampers 110 installed in the smoke control area 20 of each floor along the vertical wind direction 40. At this time, the differential pressure dampers 110 appropriately supply external air (A) to the smoke control area 20 of each floor, so that the fire smoke generated inside the fire floor 30 can escape to other floors or escape through the smoke control area 20. It is possible to prevent flow into evacuation routes such as the staircase 22 and the elevator room, and safely induce evacuation of occupants through the evacuation route connected to the smoke control area 20.

Referring to Figures 1 and 3, the differential pressure damper 110 of this embodiment can control the pressure of the smoke prevention area 20 by supplying external air (A) to the smoke prevention area 20 when a fire occurs in the building 10. there is. The differential pressure damper 110 as described above may be connected to the vertical windway 40 to receive external air (A) from the vertical windway 40, and may be installed in each floor of the building 10 in the smoke control area 20. .

The differential pressure damper 110 may include an air supply unit 112 for supplying external air A supplied from the vertical wind pipe 40 to the production area 20. At this time, when a fire occurs in the building 10, the differential pressure damper 110 changes the opening ratio of the air supply unit 112 depending on whether it is a fire floor and whether the indoor door 32 is opened or closed, so that the external air is supplied to the smoke prevention area 20. The amount of air (A) supplied can be adjusted in various ways.

For example, in this embodiment, in order to prevent the blowing amount of external air supplied to the differential pressure damper 110 from being insufficient, the fire layer and the non-fire layer are divided into the air supply unit 112 of the differential pressure damper 110. By appropriately limiting the opening ratio, the amount of air supplied to the differential pressure damper 110 can be optimized. In particular, in the non-fire floor, unlike the fire floor, the air supply portion 112 of the differential pressure damper 110 is restricted from being completely opened even if the indoor door 32 is opened, so that the air supply portion of the differential pressure damper 110 is unnecessarily reduced in the non-fire floor. Waste can be prevented.

Here, the differential pressure damper 110 adjusts the differential pressure between the smoke prevention area 20 and the indoor 30 to a preset differential pressure (e.g., 40~40) when a fire occurs in the building 10 and the indoor doors 32 are closed on all floors. It can be operated in differential pressure mode maintaining a pressure range of 60 Pa.

In addition, the differential pressure damper 110 operates at a preset smoke retardant wind speed (e.g., 0.7 m/s) from the smoke control area 20 of the fire floor toward the indoor 30 when the indoor access door 32 to the fire floor is opened. It can be operated in a smoke-proof wind speed mode that generates a smoke-proof wind speed (or more).

Meanwhile, the detailed structure and operating method of the differential pressure damper 110 of this embodiment will be described in detail again below.

Referring to FIGS. 1 to 4 , the inverter blower 120 of this embodiment can supply external air (A) to the differential pressure dampers 110 through the vertical windage 40. The inverter blower 120 may be installed in communication with the lower part of the vertical wind tunnel 40 provided in the building 10. As an example, the inverter blower 120 of this embodiment is described as being installed on the basement floor of the building 10.

The inverter blower 120 as described above may be automatically operated when a fire is detected by any one of the fire detectors 150 arranged on each floor of the building 10. That is, the inverter blower 120 can forcibly suck in external air (A) from the outside of the building 10 and then blow it to the inside of the vertical wind tunnel 40 with various blowing forces. When the operating speed of the inverter blower 120 is varied, the amount of external air (A) supplied to the differential pressure dampers 110 through the vertical wind degree 40 is varied by increasing or decreasing the blowing volume of the inverter blower 120. It can be adjusted.

For example, the inverter blower 120 includes a blowing fan 122 rotatably disposed on the vertical wind blower 40, and a drive motor 124 connected to the blowing fan to rotate the blowing fan 122. can do.

The inlet of the blower fan 122 may be connected to an intake passage for sucking in external air (A) from the outside of the building 10, and the outlet of the blower fan 122 may be connected to the lower end of the vertical windway 40. You can.

The drive motor 124 can be controlled at various speeds by the blower control panel 130. Depending on the operating speed of the driving motor 124 as described above, the blowing power of the blowing fan 122 may increase or decrease. That is, the operating speed of the drive motor 124 may be accelerated or decelerated according to the control signal transmitted by the blower control panel 130.

Referring to FIGS. 1 to 4, the blower control panel 130 of this embodiment receives a differential pressure signal indicating the differential pressure between the decontamination area 20 and the indoor 30, and based on this, determines the blowing volume of the inverter blower 120. can be controlled. In particular, in this embodiment, the operation of the inverter blower 120 is controlled based on the differential pressure between the smoke control area 20 and the indoor area 30 detected at the high and low floors of the building 10, thereby controlling the The blowing amount of external air (A) supplied to the differential pressure damper 110 can be appropriately adjusted.

In this embodiment, the blower control panel 130 is described as being installed in a location close to the inverter blower 120 on the basement floor where the inverter blower 120 is placed, but the blower control panel 130 is not limited to this and is installed on another floor of the building 10. It is also possible to become The blower control panel 130 as described above may be connected to the differential pressure signal board 140 and the drive motor 124 of the inverter blower 120 to enable signal transmission by at least one of a wired method or a wireless method. In this embodiment, for convenience of explanation, it is described as being connected in a wired manner.

For example, the blower control panel 130 converts the differential pressure signal received from the differential pressure signal board 140 into a current for controlling the drive motor 124 of the inverter blower 120 in an inverter method. It may include a switching unit 132 and an inverter motor control unit 134 that controls the driving motor 124 of the inverter blower 120 according to the control current received from the differential pressure-current switching unit 132.

The differential pressure-current conversion unit 132 receives a differential pressure signal from the differential pressure signal board 140 disposed on the lower and upper floors of the building 10, which will be described later, and then converts the control current to inverter control the operation of the inverter blower 120. can be converted to . That is, the differential pressure-current conversion unit 132 is a device that converts the differential pressure signal of the differential pressure signal board 140 into a control current, and can be converted into a current type that is easy to control the operation of the drive motor 124.

The inverter motor control unit 134 may control the operation of the drive motor 124 of the inverter blower 120 based on the control current provided by the differential pressure-current conversion unit 132. That is, the inverter motor control unit 134 can appropriately control the current supplied to the drive motor 124 using the control current provided by the differential pressure-current conversion unit 132. For reference, the inverter motor control unit 134 may be manufactured as a separate configuration connected to the differential pressure-current conversion unit 132, but may also be manufactured as a single circuit board integrated with the differential pressure-current conversion unit 132. there is.

Meanwhile, the blower control panel 130 operates the inverter blower 120 when the differential pressure between the smoke control area 20 and the indoor 30 detected in at least one of the low or high floors of the building 10 is smaller than the preset differential pressure range. ) can accelerate the operation of the inverter blower 120 to increase the blowing volume of the inverter blower 120, and the differential pressure between the smoke prevention area 20 and the indoor 30 detected on at least one of the low or high floors of the building 10 is preset. If it is greater than the differential pressure range, the operation of the inverter blower 120 can be slowed down to reduce the blowing volume of the inverter blower 120.

Therefore, the drive motor 124 of the inverter blower 120 is accelerated or decelerated by the blower control panel 130 to appropriately increase or decrease the blowing volume of the inverter blower 120, so that the external pressure supplied to the differential pressure damper 110 As the blowing amount of air A increases or decreases, the differential pressure between the smoke control area 20 and the indoor area 30 may be normalized to a preset differential pressure range.

At this time, the blower control panel 130 controls the drive motor 124 of the inverter blower 120 to maintain the normal rotation speed again when the differential pressure between the cooking area 20 and the indoor area 30 re-enters the preset differential pressure range. You can control it to do so. For example, the blower control panel 130 immediately sets the current rotational speed of the drive motor 124 to the normal rotational speed when the differential pressure between the cooking area 20 and the indoor 30 re-enters the preset differential pressure range. It can be operated at a constant rate, or after the differential pressure between the manufacturing area 20 and the indoor 30 re-enters the preset differential pressure range, the current rotation speed of the drive motor 124 is changed to the normal rotation speed after a preset time has elapsed. The current rotation speed of the drive motor 124 is set to operate consistently, or the differential pressure between the manufacturing area 20 and the indoor 30 re-enters the preset differential pressure range and reaches the average value of the preset differential pressure range. It can also be operated consistently by setting it at a normal rotation speed.

Referring to FIGS. 1 to 4 , the differential pressure signal board 140 of this embodiment may be installed in at least one of the smoke control areas 20 on each floor of the building 10. The differential pressure signal board 140 may generate a differential pressure signal corresponding to the differential pressure measured in at least one manufacturing area 20 and indoor 30 and transmit it to the blower control panel 130. Hereinafter, in this embodiment, it will be described that at least one differential pressure signal board 140 is disposed in the high and low floors of the building 10, respectively.

For example, the differential pressure signal board 140 is a first differential pressure signal board 142 disposed on at least one floor of the low-rise portion of the building 10, and the first differential pressure signal board 142 disposed on at least one floor of the high-rise portion of the building 10. It may include a second differential pressure signal board 144.

The first differential pressure signal board 142 may be provided on the differential pressure damper 110 installed on the third floor of the lower floors of the building 10. That is, the first differential pressure signal board 142 is preferably placed on an upper floor of 10 m or more from the basement among the lower floors of the building 10. For example, in this embodiment, the first differential pressure signal board 142 is set to be installed on the third floor of the building 10.

The second differential pressure signal board 144 is the highest at the average pressure of the vertical wind 40 that guides the outside air (A) supplied by the inverter blower 120 to the differential pressure dampers 110 in the high floors of the building 10. It may be provided in a differential pressure damper 110 installed on an adjacent floor. That is, the second differential pressure signal board 144 is preferably placed on a floor where the average pressure of the internal pressure of the vertical wind 40 is applied among the high floors of the building 10. For example, in this embodiment, if the building 10 has a total of 20 floors, the second differential pressure signal board 144 is set to be installed on the 15th floor of the building 10.

At this time, the first differential pressure signal board 142 can be stored inside the control box 116 of the differential pressure damper 110 placed on the third floor of the high-rise building 10, and the second differential pressure signal board 144 is It can be stored inside the control box 116 of the differential pressure damper 110 placed on the 15th floor of the high-rise building 10. The first differential pressure signal board 142 and the second differential pressure signal board 144 may be integrated into the damper controller 113 stored in the control box 116 of the differential pressure damper 110, but in this embodiment, It is manufactured as a separate part from the damper controller 113 and can be installed in different locations.

Meanwhile, on the 3rd and 15th floors of the building 10 where the first differential pressure signal board 142 and the second differential pressure signal board 144 are located, the differential pressures in the cooking area 20 and indoors 30 are within a preset differential pressure range. If it deviates upward, the differential pressure signal board that detects it first among the first differential pressure signal board 142 and the second differential pressure signal board 144 can transmit a differential pressure signal to the blower control panel 130, and the differential pressure signal board that receives the differential pressure signal can transmit the differential pressure signal to the blower control panel 130. The blower control panel 130 may control the drive motor 124 of the inverter blower 120 to a lower rotation speed than the normal rotation speed in order to reduce the blowing volume of the inverter blower 120.

In addition, on the 3rd and 15th floors of the building 10 where the first differential pressure signal board 142 and the second differential pressure signal board 144 are located, the differential pressure in the cooking area 20 and the indoor 30 is within a preset differential pressure range. If it deviates below, the differential pressure signal board that detects this first among the first differential pressure signal board 142 and the second differential pressure signal board 144 can transmit a differential pressure signal to the blower control panel 130 and receive the corresponding differential pressure signal. One blower control panel 130 may control the acceleration of the drive motor 124 of the inverter blower 120 to a higher rotation speed than the normal rotation speed in order to increase the blowing volume of the inverter blower 120.

Referring to FIGS. 1, 2, and 4, the fire detector 150 of this embodiment can detect a fire occurring indoors 30 on each floor of the building 10 in real time. The fire detector 150 may be provided on each floor of the building 10 to detect whether a fire occurs indoors 30 on each floor connected to the smoke control zones 20. At this time, the fire detector 150 may include a sensor that detects fire smoke.

The fire detector 150 on each floor can detect fire smoke generated indoors 30 on each floor of the building 10 in real time to measure whether a fire has occurred on each floor, and send the measured fire detection signal to the corresponding floor. It can be transmitted to the differential pressure damper 110. In other words, the fire detector 150 on each floor can transmit a fire detection signal to the damper controller 113 of the differential pressure damper 110 installed on the same floor, and the damper controller 113 uses the fire detection signal to determine whether the corresponding floor has a fire. It is possible to determine whether it is a fire floor or a non-fire floor.

Figure 5 is a perspective view showing the differential pressure damper 110 of the smart smoke control system 100 according to an embodiment of the present invention.

Referring to FIG. 5, the differential pressure damper 110 according to an embodiment of the present invention includes a damper housing 111, an air supply unit 112, a damper controller 113, an aperture ratio operation unit 114, and a differential pressure measurement unit 115. and a control box 116.

The differential pressure damper 110 may be installed inside the production area 20 of each floor so as to be connected to the vertical windway 40. Here, when a fire occurs in the building 10, the differential pressure damper 110 supplies the outside air (A) delivered from the vertical wind blower 40 to the smoke control area 20, so that the smoke and toxic gases of the fire are transferred to the smoke control area 20. It is also possible to prevent it from flowing in or flowing to other floors through the decontamination area (20). Therefore, in this embodiment, evacuation through the evacuation stairs or elevator connected to the fire prevention area 20 can be safely induced at the beginning of a fire outbreak, and human casualty and property damage due to fire can be minimized.

Meanwhile, the differential pressure damper 110 of this embodiment can control the amount of external air (A) supplied to the manufacturing area 20 in various ways by changing the opening ratio of the air supply unit 112. That is, when a fire occurs in the building 10, the differential pressure damper 110 detects whether the fire floor or non-fire floor corresponds to the fire floor or whether the indoor door 32 is opened, and adjusts the opening rate of the air supply unit 112 appropriately. You can change it.

The differential pressure damper 110 adjusts the opening ratio of the air supply unit 112 within a limited opening ratio when the indoor door 32 is closed to maintain the differential pressure between the smoke control area 20 and the indoor 30 within a preset differential pressure range. Can be operated in differential pressure mode.

Among the differential pressure dampers 110, the differential pressure damper disposed on the fire floor adjusts the opening rate of the air supply unit 112 at the maximum opening rate when the indoor door 32 is opened to move from the smoke control area 20 toward the indoor area 30. It can be operated in a smoke-retardant wind speed mode that generates a preset wind speed.

Here, the differential pressure damper 110 disposed on the non-fire floor among the differential pressure dampers 110 of the building 10 operates the air supply unit 112 only within a preset limited opening ratio, regardless of whether the indoor door 32 is opened or closed. Can operate open. Accordingly, the differential pressure damper 110 of the non-fire floor can prevent the amount of external air A supplied through the air supply unit 112 from becoming excessive.

In addition, among the differential pressure dampers 110 of the building 10, the differential pressure damper 110 disposed on the fire floor operates to open the air supply unit 112 within a preset limited opening ratio when the indoor door 32 is closed, When opening the indoor door 32, the limited opening ratio for the air supply unit 112 may be released or it may be opened with a maximum opening ratio greater than the limited opening ratio. Accordingly, in the differential pressure damper 110 of the fire floor where the indoor door 32 is open, the amount of external air A supplied through the air supply unit 112 can be sufficiently increased.

As described above, the air supply amount of the differential pressure dampers 110 can be stably secured depending on the fire floor and the non-fire floor, and the air supply amount of the differential pressure damper 110 on each floor is optimized, so that the differential pressure damper 110 placed on the fire floor The problem of insufficient air supply can be prevented in advance.

Referring to FIG. 5 , the damper housing 111 of this embodiment is mounted on the wall forming the manufacturing area 20 and may be connected to communicate with the vertical airway 30. An air supply unit 112 may be formed in the central area of the damper housing 111 as described above to supply external air A into the manufacturing area 20.

Referring to FIG. 5, the air supply unit 112 of this embodiment is a component for supplying external air (A) to the manufacturing area 20, and is a passage connected to the damper housing 111 and the vertical wind pipe 40. It can be prepared in any shape. The air supply portion 112 as described above is provided in a structure that can be opened and closed, and can be formed in a structure that can vary the opening ratio in an open state. That is, the differential pressure damper 110 can adjust the amount of external air (A) supplied to the manufacturing area 20 in various ways by changing the opening ratio of the air supply unit 112.

For example, in normal times when a fire does not occur, the air supply portion 112 of the differential pressure damper 110 may be maintained in a closed state, and when a fire occurs, the differential pressure damper 110 supplies external air ( A) can be opened at a preset opening ratio to properly supply air. Here, the opening ratio of the air supply unit 112 can be adjusted in various ways, but in this embodiment, the passage through which external air (A) is supplied is sealed by rotating the plurality of air supply wings 112b installed in the air supply unit 112. It can be opened or opened at an appropriate aperture ratio.

As shown in FIGS. 1 to 5, the air supply unit 112 may include an air supply opening 112a, a plurality of air supply wings 112b, and an air supply opening/closing device 112c.

Here, the air supply opening 112a is a passage for supplying external air (A), and may be formed in the central area of the front part of the damper housing 111 to enable discharge of external air (A).

Additionally, the air supply wings 112b are wing-shaped members for opening and closing the passage of the air supply opening 112a. The air supply wings 112b may be arranged to be spaced apart from each other at regular intervals in the air supply opening 112a and may be rotatably connected to both sides of the air supply opening 112a. For example, the air supply wing 112b may be provided in a louver shape extending long in the horizontal direction. Both ends of the air supply wing 112b as described above may be rotatably connected to the left and right sides of the air supply opening 112a. However, it is not limited to this, and the shape, arrangement method, and opening/closing structure of the air supply wing 112b may be variously modified depending on the design conditions and situations for the smart smoke control system 100 based on the inverter blower 120.

The air supply wings 112b as described above may be arranged adjacent to each other in an overlapping structure at the air supply opening 112a. Therefore, if the air supply wings 112b are all arranged in a vertically overlapping position, the air supply opening 112a may be shielded by the air supply wings 112b, thereby blocking the external air A supplied from the air supply opening 112a. there is. In addition, when the air supply wings 112b are simultaneously rotated from the vertically overlapped position to the inclined position, the air supply port 112a is opened by the air supply wings 112b, and the external air A is supplied from the air supply port 112a. may be discharged forward and inclined upward.

In addition, the air supply unit opener 112c is a device interoperably connected to the air supply wings 112b, and the opening rate of the air supply unit 112 can be adjusted by rotating the air supply wings 112b. The air supply opening/closing device 112c as described above may be connected to one side of the air supply wings 112b in an interlockable structure. For example, the air supply switch 112c includes an interlocking rod interlockingly connected to the air supply blades 112b, an electric motor providing driving force to rotate the air supply blades 112b, and a rotating shaft of the electric motor and the interlocking rod. It may include a power transmission member connected to the upper end and transmitting the driving force of the electric motor to the air supply blades 112b.

Meanwhile, in this embodiment, the limiting aperture ratio for the aperture ratio of the air supply unit 112 can be implemented in either a hardware method or a software method.

As a hardware method of limiting the opening ratio of the air supply section 112, the rotation angle of the air supply blades 112b is directly limited by the air supply section opener 112c, or the air supply blades 112b are rotated when the air supply blades 112b rotate. ) It is possible to limit the rotation angle of the air supply wings (112b) by placing a stopper at the position where the air supply blades (112b) are placed.

As a software method for limiting the opening ratio of the air supply unit 112, the total operating time required for the air supply unit 112 to be fully opened from a closed state can be measured, and the limited opening ratio is determined based on the total operating time. The operation limitation of the air supply unit 112 may be released according to the corresponding limitation operation time. At this time, the limited operation time can be set to be smaller than the total operating time required in the opening and closing process of the air supply unit 112, and the air supply unit 112 can be operated within the limited operating time to limit the opening rate of the air supply unit 112. there is. However, in this embodiment, if it is determined that the indoor access door 32 is open on the fire floor where the fire detection signal of the fire detector 150 is received, the operation of the above-mentioned program is stopped to open the air supply unit 112 according to the limited opening ratio. Operation restrictions can be lifted.

In particular, the air supply switch 112c may be provided to rotate the air supply blades 112b at a constant speed by the damper controller 113. Accordingly, the change in the opening rate of the air supply unit 112 is proportional to the rotation time of the air supply wings 112b rotated by the air supply opening/closing device 112c, so the air supply wings 112b move in the direction of opening the air supply opening 112a. The opening ratio of the air supply unit 112 can be adjusted using the rotated time.

At this time, as the rotation time of the air supply blades 112b increases, the rotation angle of the air supply blades 112b may increase, and as the rotation angle of the air supply blades 112b increases, the opening ratio of the air supply opening 112a may also increase. You can. Therefore, the total operating time taken until the air supply opening/closing device 112c rotates the air supply wings 112b to increase the opening rate of the air supply unit 112 from '0%' to '100%' can be measured, and so on. The measured total operating time (e.g., 10 seconds) is used to limit the operating time (e.g., 0.5 seconds) of the air supply switch 112c according to the desired opening ratio of the air supply portion 112 (e.g., 5%, 15%, 30%, or 100%). seconds, 1.5 seconds, 3 seconds or 10 seconds), the opening rate of the air supply unit 112 can be appropriately adjusted.

Referring to FIGS. 1 to 5 , the damper controller 113 of this embodiment can adjust the opening rate of the air supply unit 112 according to the detection results received from the fire detector 150 and the differential pressure measuring unit 115. The damper controller 113 is a control unit for controlling the operation of the differential pressure damper 110, and may be stored inside the control box 116. For example, the damper controller 113 may be provided as an electronically controllable PCB control board. The damper controller 113 as described above can use the fire detection signal from the fire detector 150 to determine the fire floor and the non-fire floor of the building 10.

For reference, the damper controller 113 may be provided with a terminal connected to enable signal transmission to the fire detector 150, the air supply switch 112c, and the differential pressure signal board 140, and the operation of the differential pressure damper 110 A display unit may be provided to display the status to the administrator.

The damper controller 113 of this embodiment can adjust the opening rate of the air supply unit 112 according to the detection results of the fire detector 150 and the differential pressure measurement unit 115. At this time, the damper controller 113 can detect whether a fire has occurred indoors 30 through the detection result of the fire detector 150, and detects whether a fire has occurred indoors 30 through the detection result of the differential pressure measurement unit 115. It is possible to detect whether the device is open or closed.

That is, the damper controller 113 can adjust the opening rate of the air supply unit 112 below the limit opening rate when it is detected that the indoor door 32 is closed in a situation where a fire in the indoor 30 is detected, and the indoor ( If the indoor door 32 is detected to be open in a situation where a fire in 30) is detected, the operation restriction of the proposed opening rate for the air supply unit 112 can be lifted and opened at the maximum opening rate.

Meanwhile, the damper controller 113 controls the air supply unit 112 when a fire occurs on another floor while a fire occurring indoors 30 is detected and the indoor door 32 on that floor is opened. The operation limit state according to the limited opening ratio can be maintained, and the opening ratio of the air supply unit 112 can be adjusted accordingly within the limited opening ratio. Therefore, in this embodiment, since the opening ratio of the differential pressure damper 110 of the non-fire floor is adjusted within the limited opening ratio, waste of external air (A) supplied to the non-fire floor can be prevented, and the differential pressure damper 110 of the fire floor can be prevented. Since the amount of external air (A) supplied to (110) is stably secured, the smoke prevention wind speed (W) can be stably secured in the fire floor.

Referring to FIGS. 4 and 5 , the aperture ratio control unit 114 of this embodiment may be provided in the damper controller 113 so that an administrator can change the setting of the limited aperture ratio on site when installing the differential pressure damper 110. That is, the aperture ratio control unit 114 can be used by an administrator to set or change at least one of the limited aperture ratio or the maximum aperture ratio in the field when installing the differential pressure damper 110. For example, the aperture ratio control unit 114 may be provided on one side of the damper controller 113 as a switch member or button member that can be manually operated by an administrator.

For example, in this embodiment, the limiting aperture ratio may be set to 30% of the maximum aperture ratio of the air supply unit 112 by manipulating the aperture ratio manipulator 114, and the maximum aperture ratio is set by manipulator of the aperture ratio manipulator 114. The maximum opening ratio of the air supply unit 112 can be set to 100%. The set values for the limit opening ratio and maximum opening ratio of the air supply unit 112 as described above are different values (e.g., 5%, 15%, or 70%, etc.) by the manager depending on the design conditions and circumstances of the smart smoke control system 100. may be changed to

Referring to FIGS. 1 to 5 , the differential pressure measuring unit 115 of this embodiment can detect the differential pressure between the indoor 30 and the cooking area 20 on each floor of the building 10 in real time. The differential pressure measuring unit 115 as described above is installed indoors 30 on each floor of the building 10, and the detection result of the differential pressure measuring unit 115 may be transmitted to the damper controller 113 in real time.

Here, the detection results of the differential pressure measuring unit 115 arranged on the 3rd and 15th floors of the building 10 are transmitted to the differential pressure signal board 140 arranged on the 3rd and 15th floors together with the damper controller 113, respectively. You can. However, it is not limited to this, and the detection result of the differential pressure measuring unit 115 arranged on the 3rd and 15th floors of the building 10 is first transmitted to the damper controller 113, and then a differential pressure signal is sent through the damper controller 113. It may also be possible to transmit it to the board 140.

In addition, the differential pressure measuring unit 115 may be installed separately from the differential pressure damper 110 in either the manufacturing area 20 or indoors 30, but in this embodiment, the differential pressure measuring unit 115 It is explained as being installed on the differential pressure damper 110. For example, the differential pressure measuring unit 115 is a differential pressure sensor (not shown) connected to the damper controller 113 of the differential pressure damper 110, one end is connected to one side of the differential pressure sensor, and the other end is connected to the inside of the indoor 30. It may include an indoor air pipe 115a disposed, and a production area side air pipe 115b having one end connected to the other side of the differential pressure sensor and the other end disposed inside the production zone 20.

The indoor air pipe 115a may be provided in the shape of a hose to transmit the internal pressure of the indoor 30 to the differential pressure sensor. Accordingly, the pressure inside the indoor 30 can be transmitted in real time to the differential pressure sensor installed inside the differential pressure damper 110 through the indoor air pipe 115a.

The air pipe 115b on the manufacturing area side may be provided in the shape of a hose to transmit the internal pressure of the manufacturing area 20 to the differential pressure sensor. Accordingly, the pressure of the manufacturing area 20 can be transmitted in real time to the differential pressure sensor installed inside the differential pressure damper 110 through the manufacturing area side air pipe 115b. The air pipe 115b on the manufacturing area side as described above may be provided to penetrate the lower part of the damper housing 111.

The differential pressure sensor compares the pressures of the smoke prevention area 20 and the indoor air pipe 115a transmitted through the smoke prevention area side air pipe 115b and the indoor air pipe 115a to determine the pressure generated between the smoke prevention area 20 and the indoor air pipe 115a. Differential pressure can be measured in real time. Hereinafter, in this embodiment, the differential pressure sensor may be provided in a structure integrated with the damper controller 113.

Referring to FIGS. 1 to 3 and 5 , the control box 116 of this embodiment may be provided in the damper housing 111 to accommodate the damper controller 113. The control box 116 may be formed in a box shape on the upper side of the air supply unit 112. The front of the control box 116 as described above may be provided with a door that can be opened and closed by an administrator.

The first differential pressure signal board 142 can be stored together with the damper controller 113 in the control box 116 of the differential pressure damper 110 installed on the 3rd floor of the building 10, and on the 15th floor of the building 10. A second differential pressure signal board 144 may be stored together with the damper controller 113 in the control box 116 of the installed differential pressure damper 110.

As seen above, in this embodiment, the blower control panel 130 is controlled according to the differential pressure signals of the first differential pressure signal board 142 and the second differential pressure signal board 144 installed on the 3rd and 15th floors of the high-rise building 10. By appropriately adjusting the blowing volume of the inverter blower 120, the blowing volume of external air (A) supplied to the differential pressure damper 110 of each floor through the vertical wind degree 40 can be optimized according to the fire occurrence situation, and At the same time, depending on the operating environment of the differential pressure damper 110 on each floor (e.g., whether it is a fire floor or a non-fire floor, or whether the indoor door 32 is open or closed, etc.), the opening rate of the air supply unit 112 is limited or the opening rate restriction is lifted for each floor. The air supply volume of the differential pressure dampers 110 installed in can be stably secured. In particular, the differential pressure damper 110 installed on the non-fire floor limits the opening ratio of the air supply unit 112 to a preset limit opening ratio regardless of whether the indoor door 32 is opened or closed when a fire occurs, thereby reducing the differential pressure damper 110 on the non-fire floor. By solving the problem of excessive supply of external air (A) from the fire prevention area (20), waste of the amount of external air (A) supplied in the non-fire floor can be prevented.

Therefore, in the smart smoke control system 100 of this embodiment, the blower control panel 130 controls the blowing volume of the inverter blower 120 according to the differential pressure signal from the differential pressure signal board 140 installed in the high and low floors of the building 10. In addition, through a method of limiting the opening ratio of the air supply portion 112 of the differential pressure dampers 110, the air supply volume of at least one of the differential pressure dampers 110 installed in the building 10 is abnormally insufficient or excessively increased. It is possible to actively respond to problems, and the differential pressure dampers 110 can operate smoothly in differential pressure mode and smoke prevention wind speed mode depending on the fire situation.
