Description

Smart smoke control system based on composite damper {SMART SMOKE CONTROLLING SYSTEM BASED ON COMPLEX DAMPER}

The present invention relates to a smart smoke control system based on a complex damper. More specifically, the present invention relates to a smart smoke control system based on a complex damper. More specifically, the differential pressure is controlled by controlling the blowing amount of external air flowing in vertically from the blower based on the differential pressure generated between the smoke control area and indoors when a fire occurs in a building. This is about a smart smoke control system based on a composite damper that can properly supply outside air to the damper.

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 fire situations that occur during a building fire.

In reality, a typical smoke control device installed in a building 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 when a fire occurs, they are opened at a preset opening rate to keep the differential pressure between the smoke prevention area and the indoors within the required pressure range (for example, the differential pressure between the smoke prevention area and the indoors 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 for the evacuation of occupants from the fire floor, and the smoke prevention wind speed required for the indoor access door in the fire smoke area is increased. Ensure (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 prevention area may be insufficient in the event of a fire in the building. Conversely, if the design air volume of the blower is too high, the air supplied from the differential pressure damper to the smoke prevention area may be insufficient in the event of a fire in the building. There may be too much air supply.

In other words, if all the doors to the smoke control area on each floor are closed and the air supply from the differential pressure damper is excessive, the pressure in the smoke control area increases excessively, causing a situation in which occupants cannot or find it difficult to open the doors due to the overpressure in the smoke control area. There is a problem. In addition, if all the doors to the smoke control area on each floor are closed and the air supply from the differential pressure damper is insufficient, the pressure in the smoke control area decreases, which reduces the pressure differential between the smoke control area and the interior, 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, research and development on a smoke control system that satisfies all the smoke control performance requirements of smoke control equipment has been continuously conducted in recent years. 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).

The performance of the differential pressure damper can be stabilized by optimizing it accordingly.

In addition, the smart smoke control system based on a composite damper according to an embodiment of the present invention appropriately controls the operation of the composite damper and return damper through differential pressure signals from the differential pressure signal board placed on the high and low floors of the building when a fire occurs in the building. Because of its structure, it is possible to optimize the smoke control performance of the smart smoke control system by actively responding to fire situations in the building, and also prevent the problem of insufficient or excessive air supply to the smoke control damper on each floor when a fire occurs in the building. Therefore, in this embodiment, the air supply amount of the differential pressure damper placed on each floor of the building can be easily controlled using the differential pressure signal of the differential pressure signal board installed on a specific floor of the building, and the differential pressure in the manufacturing area and indoors is preset.

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 a composite damper 130 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 composite damper 130 according to an embodiment of the present invention includes a differential pressure damper 110, a blower 120, a composite damper 130, and a return damper. (140), differential pressure signal board (150) and fire detector (160).

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 to 4, 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 rate of the air supply unit 112 depending on whether it is a fire floor and whether the indoor door 32 is opened or closed to supply air to the smoke control area 20. The supply amount of external air (A) can be appropriately adjusted.

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 rate, 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 3, the blower 120 of this embodiment can supply external air (A) to the differential pressure dampers 110 through the vertical wind direction 40 with a blowing force of a certain size. The blower 120 may be installed in communication with the lower part of the vertical wind tunnel 40 provided in the building 10. The blower 120 as described above may be automatically activated when a fire is detected by any one of the fire detectors 160 arranged on each floor of the building 10.

Accordingly, the 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 windshield 40 at a constant designed air volume. As an example, the blower 120 of this embodiment is described as being installed on the basement floor of the building 10.

Here, an intake airflow 126 for guiding the intake of external air A from the outside of the building 10 may be connected to the intake port of the blower 120. An intake filter 122 may be provided inside either the intake port or the intake airflow 126 of the blower 120 to filter external air A drawn from the outside. Hereinafter, in this embodiment, the intake filter 122 will be described as being provided inside the intake airflow 126.

In addition, the outlet of the blower 120 and the lower part of the vertical wind pipe 40 are connected to a blower wind pipe 136 that guides the outside air (A) discharged from the outlet of the blower 120 to the inside of the vertical wind pipe 40. can be connected An outlet filter 124 may be provided inside either the outlet of the blower 120 or the blower 136 to filter the external air A discharged from the blower 120. Hereinafter, in this embodiment, it will be described that the outlet filter 124 is provided inside the blower 136.

Referring to FIGS. 1 to 4, the composite damper 130 of this embodiment adjusts the blowing amount of external air (A) flowing from the blower 120 to the vertical windage 40 appropriately according to the fire situation of the building 10. It can be adjusted properly. That is, the composite damper 130 receives a differential pressure signal representing the differential pressure between the manufacturing area 20 and the indoor 30 from the differential pressure signal board 150, and based on this, the blower 120 converts the vertical wind speed 40 to The blowing volume of incoming external air (A) can be adjusted. The composite damper 130 as described above may be disposed in communication between the blower 120 and the vertical wind pipe 40.

For example, the complex damper 130 may include a manual damper unit 132 and an automatic damper unit 134. That is, the composite damper 130 is an automatic damper unit 134 according to the differential pressure signal received from the differential pressure signal board 150 to control the blowing amount of external air (A) flowing into the vertical windway 40 from the blower 120. ) can control the opening rate.

The manual damper unit 132 and the automatic damper unit 134 as described above may be disposed inside the blower 136 connected between the blower 120 and the vertical wind blower 40. Hereinafter, in this embodiment, the manual damper unit 132 and the automatic damper unit 134 will be described as being provided in an integrated structure, but the manual damper unit 132 and the automatic damper unit 134 are installed in the inside of the blowing wind pipe 136. It is also possible to install them individually.

Here, the manual damper unit 132 may be set to a preset opening rate by the manager's manual work when installing the composite damper 130. That is, the manual damper unit 132 can maintain an always open state at a preset opening rate. Therefore, when the blower 120 is activated when a fire occurs in the building 10, a certain amount of the outside air (A) blown by the blower 120 is blown into the vertical windshield 40 through the manual damper unit 132. It can be.

In addition, the automatic damper unit 134 is set in a shielded state when the composite damper 130 is installed, but can be automatically opened by a differential pressure signal from the differential pressure signal board 150 when a fire occurs in the building 10. In this embodiment, the differential pressure signal board 150 is installed in the high and low floors of the building 10, respectively, and when a fire occurs in the building 10, the differential pressure between the smoke prevention area 20 and the indoor 30 is, for example, 40 Pa or less or 60 Pa or more. The differential pressure signal board 150, which detects first, can generate a corresponding differential pressure signal and transmit it to the composite damper 130. At this time, the complex damper 130 opens the automatic damper unit 134 according to the detection result of the differential pressure signal board 150, and can appropriately control the opening rate of the automatic damper unit 134.

As described above, when the automatic damper unit 134 is opened by the differential pressure signal from the differential pressure signal board 150 when a fire occurs in the building 10, the maximum blowing amount of outside air (A) blown by the blower 120 is the automatic damper. The blowing volume that is smaller than the maximum blowing volume of the external air (A) transmitted as is to the vertical wind direction 40 through the blower 134 and the manual damper portion 132, or blown by the blower 120, is connected to the automatic damper portion 134 and It can be appropriately transmitted to the vertical wind 40 through the passive damper unit 132.

As shown in FIGS. 1 and 2, the manual damper unit 132 and the automatic damper unit 134 may be provided in various structures that can open and close the internal passage of the blower wind pipe 136, but in this embodiment, Similar to the air supply portion 112 of the differential pressure damper 110 described later, the damper blade may be provided to be rotatable and may be provided in a structure in which the damper blade is opened and closed or the opening rate is adjusted depending on the rotation angle of the damper blade.

Here, the manual damper unit 132 is fixed with the damper blade rotated at a preset angle by the manager when installing the composite damper 130, so the blowing volume of the external air (A) passing through the manual damper unit 132 can always be maintained constant by the opening rate of the manual damper unit 132 set by the manager.

In addition, the automatic damper unit 134 is in a shielded state when the composite damper 130 is installed, but when a fire occurs in the building 10, the damper blade is rotated at various angles by the differential pressure signal from the differential pressure signal board 150, and the damper blade is rotated to various sizes. Since it is opened at an opening rate, it can be opened according to the fire detection signal from the fire detector 160, and the opening rate of the automatic damper unit 134 is changed by the differential pressure signal from the differential pressure signal board 150, allowing external air (A) to be released. The blowing volume can be adjusted in various ways.

1 to 4, the return damper 140 of this embodiment is used to return a portion of the external air (A) blown from the blower 120 to the composite damper 130 to the inlet side of the blower 120. It is a composition. That is, the return damper 140 can return a portion of the external air (A) discharged from the blower 120 from the outlet side of the blower 120 to the intake side of the blower 120. The return damper 140 as described above is formed in an opening and closing structure similar to the automatic damper unit 134, but has a return air flow 142 for guiding a portion of the external air A returned through the return damper 140. can be placed in

Here, the return airflow 142 may be formed to guide a portion of the external air (A) blown from the blower 120 to the composite damper 130 to the intake port of the blower 120. For example, one end of the return wind blower 142 may be connected in communication with the blowing wind blower 136, and the other end of the return wind blower 142 may be connected in communication with the intake wind blower 126. At this time, the connection portion of the return wind direction 142 and the blowing wind direction 136 may be located between the outlet of the blower 120 and the composite damper 130. The connection portion of the return airflow 142 and the intake airflow 126 may be located between the inlet and outlet of the intake airflow 126.

In addition, the return damper 140 can be automatically opened and closed by the fire detection signal of the fire detector 160 and the differential pressure signal of the differential pressure signal board 150, similarly to the automatic damper unit 134. That is, the return damper 140 may be opened or closed by a differential pressure signal from the differential pressure signal board 150 when a fire occurs in the building 10. If the return damper 140 is opened according to the differential pressure signal of the differential pressure signal board 150, part of the external air (A) blown by the blower 120 is returned through the return damper 140. After flowing into the interior, the wind blowing wind may be returned to the interior of the wind pipe 136 along the return wind path 142.

The return damper 140 as described above can receive a differential pressure signal directly from the differential pressure signal board 150 and operate independently without being affected by the operating state of the composite damper 130. However, in this embodiment, the return damper 140 is described as interlocking with the composite damper 130 that receives the differential pressure signal from the differential pressure signal board 150. That is, in this embodiment, the composite damper 130 operates by first receiving the differential pressure signal from the differential pressure signal board 150, and generates an operating signal of the return damper 140 according to the differential pressure signal from the differential pressure signal board 150. It can be provided to the return damper 140. At this time, the return damper 140 may be opened and closed according to an operation signal transmitted from the composite damper 130.

As shown in FIG. 1, when the return damper 140 is opened by the differential pressure signal of the differential pressure signal board 150, some of the external air (A) blown by the blower 120 is connected to the return damper 140. It can be returned to the inlet side of the blower 120 through the return wind 142, and the remainder of the outside air (A) blown by the blower 120 that is not returned is the vertical wind 40 through the composite damper 130. can be blown through. As a result, only the outside air (A) that is not returned through the return damper 140 and the return wind blower 142 among the total blowing volume of the blower 120 is sent to the differential pressure damper of each floor through the composite damper 130 and the vertical wind blower 140. It can be blown to (110).

As shown in FIG. 2, when the return damper 140 is shielded by the differential pressure signal of the differential pressure signal board 150, the external air (A) blown by the blower 120 is connected to the return damper 140 and the return wind. Since it does not return through 142, the entire air volume of the blower 120 can be blown to the composite damper 130. As a result, the entire air volume of the blower 120 is blown to the composite damper 130, so the entire air volume of the blower 120 is blown to the differential pressure damper 110 of each floor through the composite damper 130 and the vertical wind pipe 40. It can be.

Meanwhile, in this embodiment, even if the blower 120, which is cheaper than the inverter blower and has a constant blowing volume, is used, the composite damper 130 is operated according to the differential pressure signal of the differential pressure signal board 150 and the fire detection signal of the fire generator 160. )'s automatic damper unit 134 and return damper 140 are selectively opened and closed or the opening rate of the automatic damper unit 134 and return damper 140 is adjusted to allow vertical wind to flow from the blower 120 to the vertical wind direction 40. The blowing amount of external air (A) can be appropriately changed. Therefore, the blower 120 of this embodiment can control the blowing amount of the external air (A) supplied to the vertical wind degree 40 in various ways even without using an inverter type blower that independently adjusts the blowing amount of the external air (A). Accordingly, the unit cost of the blower 120 can be significantly reduced, providing an advantage in terms of installation cost.

Referring to FIGS. 1 to 4, the differential pressure signal board 150 of this embodiment can generate a differential pressure signal corresponding to the measured differential pressure between the manufacturing area 20 and the indoor 30 and transmit it to the composite damper 130. there is. The differential pressure signal board 150 may be installed in at least one smoke control area 20 among the smoke control areas 20 on each floor of the building 10. For example, the differential pressure signal board 150 may be placed in the high and low floors of the building 10, respectively.

Therefore, in this embodiment, the differential pressure signal board 150 at the high and low floors of the building 10 can generate a differential pressure signal according to the differential pressure between the manufacturing area 20 and the indoor 30 and then transmit it to the composite damper 130. In addition, the automatic damper part 132 and the return damper 140 of the composite damper 130 open and close according to the differential pressure signal of the differential pressure signal board 150 to allow external air flowing from the blower 120 to the vertical wind blower 40 ( The blowing volume of A) can be adjusted appropriately. That is, the differential pressure signal board 150 automatically operates the composite damper 130 according to the differential pressure detected by the differential pressure measuring unit 115 of the differential pressure damper 110 installed on at least one of the high and low floors of the building 10. The operation of the damper unit 134 and the return damper 140 can be controlled.

For example, the differential pressure signal board 150 is a first differential pressure signal board 152 disposed on at least one floor of the lower floor of the building 10, and a first differential pressure signal board 152 disposed on at least one floor of the upper floor of the building 10. It may include a second differential pressure signal board 154.

The first differential pressure signal board 152 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 152 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, it is set that the first differential pressure signal board 152 is installed on the third floor of the building 10, and is not installed on other lower floors.

The second differential pressure signal board 154 is closest to the average pressure of the vertical wind 40 that guides the outside air (A) supplied by the blower 120 to the differential pressure dampers 110 among the high floors of the building 10. It may be provided in the differential pressure damper 110 installed on the floor. That is, the second differential pressure signal board 154 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, when the building 10 has a total of 20 floors, the second differential pressure signal board 154 is installed only on the 15th floor of the building 10 and is not installed on other upper floors.

At this time, the first differential pressure signal board 152 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 154 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 152 and the second differential pressure signal board 154 may be built in an integrated structure in the damper controller 113 stored in the control box 116 of the differential pressure damper 110. However, in this embodiment, the first differential pressure signal board 152 and the second differential pressure signal board 154 are manufactured as separate parts from the damper controller 113 and are individually installed inside the control box 116. do.

Meanwhile, the operation of the composite damper 130 is controlled according to the differential pressure signals of the first differential pressure signal board 152 and the second differential pressure signal board 154 as follows.

As shown in FIG. 1, the differential pressure of the smoke prevention area 20 and the indoor area 30 is on the 3rd and 15th floors of the building 10 where the first differential pressure signal board 152 and the second differential pressure signal board 154 are located. If the preset differential pressure range is exceeded, the differential pressure signal board that detects it first among the first differential pressure signal board 152 and the second differential pressure signal board 154 may transmit the differential pressure signal to the composite damper 130, and The composite damper 130 that receives the differential pressure signal may operate with the automatic damper unit 134 closed in order to reduce the blowing amount of external air (A) flowing from the blower 120 to the vertical wind pipe 40.

As shown in FIG. 2, the differential pressure of the smoke prevention area 20 and the indoor area 30 is on the 3rd and 15th floors of the building 10 where the first differential pressure signal board 152 and the second differential pressure signal board 154 are located. If it deviates below this preset differential pressure range, the differential pressure signal board that detects it first among the first differential pressure signal board 152 and the second differential pressure signal board 154 can transmit a differential pressure signal to the composite damper 130, The composite panel 130 that receives the corresponding differential pressure signal may operate with the automatic damper unit 134 opened in order to increase the blowing amount of external air (A) flowing from the blower 120 to the vertical wind pipe 40.

In addition, the operation of the return damper 140 is controlled according to the differential pressure signals of the first differential pressure signal board 152 and the second differential pressure signal board 154 as follows.

As shown in FIG. 1, the differential pressure of the smoke prevention area 20 and the indoor area 30 is on the 3rd and 15th floors of the building 10 where the first differential pressure signal board 152 and the second differential pressure signal board 154 are located. When the preset differential pressure range is exceeded, the return damper 140 may operate in an open state to reduce the amount of external air (A) flowing from the blower 120 into the vertical wind direction 40. That is, the return damper 140 is linked in the open state while the automatic damper unit 134 of the composite damper 130 operates in the closed state.

As shown in FIG. 2, the differential pressure of the smoke prevention area 20 and the indoor area 30 is on the 3rd and 15th floors of the building 10 where the first differential pressure signal board 152 and the second differential pressure signal board 154 are located. When the preset differential pressure range is exceeded, the return damper 140 may operate in a closed state to increase the blowing amount of external air A flowing from the blower 120 into the vertical wind direction 40. That is, the return damper 140 is interlocked in a closed state while the automatic damper unit 134 of the composite damper 130 operates in an open state.

Meanwhile, the differential pressure signal board 150 distinguishes the fire floor and the non-fire floor through the detection results of the fire detector 160 and the differential pressure measuring unit 115 when a fire occurs in the building 10, and also uses the differential pressure damper 110. It is desirable to automatically control the operation of the automatic damper unit 134 and the return damper 140 of the composite damper 130 by distinguishing their operating modes (for example, differential pressure mode or smoke-retardant wind speed mode).

That is, the first differential pressure signal board 152 and the second differential pressure signal board 154 are configured so that when a fire occurs in the building 10, all differential pressure dampers 110 on each floor are operated in differential pressure mode or the differential pressure dampers 110 on the fire floor are operated in differential pressure mode. When operated in a smoke-resistance wind speed mode, a differential pressure signal corresponding to the detection result of the differential pressure measuring unit 115 disposed on the 3rd and 15th floors of the building 10 may be generated. The composite damper 130 and the return damper 140 receive a differential pressure signal from any one of the first and second differential pressure signal boards 152 and 154, and open and close appropriately to change the vertical wind speed 40 from the blower 120. The blowing volume of incoming external air (A) can be adjusted.

As shown in FIG. 1, when all differential pressure dampers 110 are operated in differential pressure mode, the automatic damper unit 134 is shielded by the differential pressure signals from the first and second differential pressure signal boards 152 and 153. The return damper 140 may be opened at a preset opening rate. At this time, a portion of the total blowing volume of the blower 120 may be returned to the inlet side of the blower 120 through the return damper 140, and the remainder of the total blowing volume of the blower 120 may be returned to the passive damper portion of the composite damper 130. It can be provided as vertical windage (40) through (132). Therefore, the supply amount of external air (A) supplied to the differential pressure dampers 110 through the vertical wind degree 40 is reduced compared to the total blowing volume of the blower 120, so that the air supply amount to the differential pressure dampers 110 is appropriate for the differential pressure mode. can be secured.

As shown in FIG. 2, when at least one of the differential pressure dampers 110 is operated in the smoke-proof wind speed mode, the automatic damper unit ( 134) may be opened at a preset opening rate and the return damper 140 may be shielded. At this time, the total blowing volume of the blower 120 may be provided as the vertical wind speed 40 through the manual damper unit 132 and the automatic damper unit 134 of the composite damper 130. Therefore, the supply amount of external air (A) supplied to the differential pressure dampers 110 through the vertical wind speed 40 is increased to the maximum, so that the air supply amount of the differential pressure dampers 110 operated in the smoke-proof wind speed mode is appropriate for the smoke-proof wind speed mode. can be secured.

Meanwhile, in the smart smoke control system 100 of this embodiment, the differential pressure measuring unit 115 of the differential pressure dampers 110 installed on the 3rd and 15th floors of the building 10 in the differential pressure mode or smoke prevention wind speed mode of the differential pressure dampers 110 By changing the opening rate of the automatic damper part 132 and the return damper 140 of the composite damper 130 according to the differential pressure measured in ) It is also possible to adjust the supply amount.

For example, when at least one of the differential pressure dampers 110 is operated in the smoke prevention wind speed mode, the differential pressure of the differential pressure measuring unit 115 disposed on at least one of the 3rd floor or the 15th floor of the building 10 is If it is smaller than the preset differential pressure range, the opening rate of the automatic damper unit 134 is increased according to the differential pressure signal of at least one of the first differential pressure signal board 152 and the second differential pressure signal board 154, thereby increasing the composite damper 130. ) of the manual damper unit 132 and the automatic damper unit 134 can further increase the blowing amount of external air (A) flowing into the vertical wind pipe 40. As a result, the amount of air supplied to the differential pressure dampers 110 increases, so that the differential pressure between the decontamination area 20 and the indoor 30 can be normalized to a preset differential pressure range, and the indoor 30 in the decontamination area 20 of the fire floor Smoke-reducing wind speeds generated toward can also be formed stably. Therefore, when the differential pressure damper 110 of the fire floor is operated in the smoke prevention wind speed mode, the problem of lowering the smoke prevention wind speed caused by insufficient air supply to the differential pressure damper 110 can be solved.

In addition, when at least one of the differential pressure dampers 110 is operated in the smoke prevention wind speed mode, the differential pressure of the differential pressure measuring unit 115 disposed on at least one of the 3rd floor or the 15th floor of the building 10 is preset. If it is greater than the differential pressure range, the opening rate of the automatic damper unit 134 is reduced according to the differential pressure signal of at least one of the first differential pressure signal board 152 and the second differential pressure signal board 154 to manually activate the composite damper 130. The blowing amount of external air (A) flowing into the vertical windway 40 can be further reduced through the damper unit 132 and the automatic damper unit 134. As a result, the amount of air supplied to the differential pressure dampers 110 is reduced, so that the differential pressure between the decontamination area 20 and the indoor 30 can be normalized to the preset differential pressure, and the indoor 30 is maintained in the decontamination area 20 of the fire floor. The smoke-reducing wind speed generated in this direction can also be stably secured. Therefore, when the differential pressure damper 110 on the fire floor is operated in the smoke prevention wind speed mode, the differential pressure between the smoke prevention area 20 and the indoor 30 on the non-fire floor increases significantly due to the excessive air supply amount of the differential pressure damper 110, thereby significantly increasing the indoor pressure. The problem of not being able to open the entrance door 32 or being difficult to open can be solved.

For reference, in the smart smoke control system 100 of this embodiment, when all differential pressure dampers 110 are operated in differential pressure mode, a differential pressure measuring unit ( The opening rate of the return damper 140 is also adjusted by the differential pressure signals of the first differential pressure signal board 152 and the second differential pressure signal board 154 corresponding to the differential pressure of 115, and the vertical wind speed 40 is controlled through the composite damper 130. It is also possible to increase or decrease the blowing amount of external air (A) flowing into ). For example, when all differential pressure dampers 110 are operated in differential pressure mode, the differential pressure of the differential pressure measuring unit 115 disposed on at least one of the 3rd or 15th floor of the building 10 is smaller than the preset differential pressure range. In this case, the return damper 140 can reduce the opening rate according to the differential pressure signals of the first differential pressure signal board 152 and the second differential pressure signal board 154 in the open state, and the return damper 140 accordingly. It is also possible to increase the blowing amount of external air (A) flowing into the vertical windway 40 through the passive damper part 132 of the composite damper 130 by reducing the return amount of external air (A).

Referring to FIGS. 1 to 4 , the fire detector 160 of this embodiment can detect a fire occurring indoors 30 on each floor of the building 10 in real time. The fire detector 160 as described above may include a sensor that detects fire smoke. Therefore, the fire detector 160 on each floor can measure whether a fire has occurred on each floor by detecting fire smoke generated indoors 30 on each floor, and transmit a fire detection signal to the differential pressure damper 110 on the corresponding floor. You can.

The fire detector 160 on each floor may transmit a fire detection signal to the damper controller 113 of the differential pressure damper 110, which will be described later. In particular, the fire detectors 160 installed on the 3rd and 15th floors transmit fire detection signals to the damper controller 113 of the differential pressure damper 110 arranged on the 3rd and 15th floors, respectively, and at the same time, the first differential pressure Fire detection signals can also be transmitted to the signal board 152 and the second differential pressure signal board 154, respectively. Hereinafter, in this embodiment, the fire detection signal from the fire detector 160 installed on the 3rd and 15th floors is first transmitted to the damper controller 113 and then transmitted to the first differential pressure signal board 152 and the first differential pressure signal board 152 through the damper controller 113. 2 It is described as being transmitted to the differential pressure signal board 154, but it is not limited to this and the fire detection signal of the fire detector 160 is directly transmitted to the first differential pressure signal board 152 and the second differential pressure signal board 154. It is also possible.

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 limiting opening ratio for the air supply unit 112 may be released or the opening may be performed at a maximum opening ratio greater than the limiting 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 door 32 is open on the fire floor where the fire detection signal of the fire detector 160 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 160 and the differential pressure measuring unit 115.
