Description
Technical Field
The invention relates to a comprehensive smoke control system.
Background
The smoke control technology is to grasp the time of fire growth when a fire occurs in a building, and to control the movement of smoke generated inside the building and clean and safe air flow to secure safety from the smoke generated when the fire occurs. In particular, since clean air and fumes flow from a high pressure to a low pressure, controlling the physical flow of such air and fumes can be said to control the pressure inside the building.
Smoke control devices are systems that use mechanical means such as blowers or exhaust devices to emit smoke or burn toxic gases in the event of a fire. These fume control devices can be broadly divided into fume control (smoke control) facilities that pressurize between physical barriers with blowers to prevent fumes from entering the pressurized space; or a smoke evacuation (smoke ventilation) facility that forcibly discharges smoke into the room through an exhaust.
In particular, in a high-rise building, it is necessary to provide a smoke control device using an air supply pressurization system so that external air is forcibly pressurized at a landing provided for boarding an emergency elevator or evacuating an elevator, in order to prevent intrusion of smoke moving due to a fire by a pressure difference, the landing is used for a firefighter to determine a place where a fire-fighting activity is performed or for a resident to evacuate safely.
However, in the conventional flue gas control device using air supply pressurization, the construction is mainly performed by a method of installing a dedicated vertical duct (duct) alone and installing a differential pressure damper to pressurize a stairwell, a front room, a landing, etc., and in this case, if a moving passage of an elevator, i.e., an elevator hoistway, is used as the air supply duct (duct), there is an advantage that the duct and the masonry cost can be reduced and the space area of the dedicated duct can be utilized.
In particular, an automatic differential pressure damper is mainly provided on the existing damper for pressurizing the supply air such that the operation is performed by a differential pressure sensor for measuring the pressure difference between the smoke control zone and the room at a predetermined level (for example, a pressure difference of 50 Pa), and it is difficult to actively cope with various situations that may occur when a fire occurs to supply air to a landing (front room) since fresh air is supplied to the smoke control zone only by means of the pressure difference between the smoke control zone and the room at each floor.
In addition, the existing smoke control system cannot control the damper provided at each floor separately in consideration of factors other than the pressure difference between the smoke control zone and the room at each floor. Further, since it is difficult to rapidly cope with pressure changes of a landing (front room) that occur when a fire door provided in the landing (front room) is opened, and it is also difficult to accurately measure pressure changes that occur due to air amounts that leak from gaps of walls between an elevator door and the landing or between the elevator door and an elevator hoistway, and air amounts that leak from various gaps of the front room, it is difficult to accurately control a damper, and furthermore, it is difficult to secure a place for firefighters to perform fire activities or to safely evacuate occupants.
The background art of the present invention is disclosed in korean laid-open patent publication No. 10-1956787.

However, the effects obtainable in the present invention are not limited to the above effects, and other effects may also exist.

FIG. 1 is a schematic block diagram of an integrated flue gas control system according to one embodiment of the present invention.
Referring to fig. 1, an integrated flue gas control system 1000 according to an embodiment of the present invention may include: the fire detector 10, the air supply fan 20, the air supply duct 100, the front room 200, the air supply damper 30, and the integrated control unit 40.
The fire detector 10, the air supply fan 20, the air supply damper 30, and the integrated control part 40 of the integrated smoke control system 1000 may be connected to each other through a network 50, the network 50 refers to a connection structure in which information can be exchanged between each node such as a plurality of terminals and a plurality of servers, and these networks include, for example, a third generation partnership project (3GPP,3rd Generation Partnership Project) network, a long term evolution (LTE, long Term Evolution) network, a 5G network, a worldwide interoperability for microwave access (WIMAX, world Interoperability for Microwave Access) network, the Internet (Internet), a local area network (LAN, local Area Network), a wide area network (WAN, wide Area Network), a personal area network (PAN, personal Area Network), a wifi network, a Bluetooth (Bluetooth) network, a satellite broadcasting network, an analog broadcasting network, a DMB (Digital Multimedia Broadcasting) network, and the like, but are not limited thereto. The sensing devices such as the differential pressure sensor 201, the fire door sensor 202, and the smoke prevention wind speed sensor 203, which will be described later, may be connected to the integrated control unit 40 via the network 50.
The fire detector 10 may sense whether a fire occurs in a building. In addition, when a fire occurs in a building, the fire detector 10 may transmit a fire detection signal to the integrated control part 40 to inform the occurrence of the fire.
Further, the fire detector 10 may be understood as a heat detector, a smoke detector, a gas detector, a human body detector, etc., including concepts of various detectors (sensors) for measuring signals that can determine whether a fire has occurred.
Furthermore, according to an embodiment of the present invention, when a fire occurs in a building, the fire detector 10 may sense information associated with the location of the occurrence of the fire. At this time, the fire detector 10 may transmit information associated with the sensed location of the occurrence of the fire to the integrated control part 40.
The integrated Control part 40 may be understood as being provided in a Control Room (Control Room), a status Room, etc., for acquiring various information associated with a fire in a building provided with the integrated smoke Control system 1000 according to an embodiment of the present invention, and controlling each structure of the integrated smoke Control system 1000 according to an embodiment of the present invention (in particular, opening or closing of the air supply damper 30, driving of the air supply fan 20, etc. for each floor of the building) based on the acquired information.
Referring to fig. 1, the integrated control part 40 may be provided in a local area (e.g., basement, etc.) within a building provided with the integrated smoke control system 1000 according to an embodiment of the present invention, but is not limited thereto. As another example, the control tower may be provided in a building such as a control tower, and the control tower may be provided separately outside the building provided with the integrated flue gas control system 1000 according to an embodiment of the present invention.
Here, the information related to the location of occurrence of the fire may include a floor where the fire occurs in the building (hereinafter referred to as a fire occurrence floor), a more specific fire occurrence location among the fire occurrence floors, a fire occurrence floor, and occupant information of up-down predetermined floors preset for the fire occurrence floor, and the like.
In addition, according to an embodiment of the present invention, when a fire occurs in a building, the fire detector 10 may sense information associated with the intensity of the occurrence of the fire. At this time, the fire detector 10 may transmit information associated with the sensed intensity of occurrence of the fire to the integrated control part 40.
The air supply duct 100 is an inflow passage of air outside the building, and the air supply duct 100 in the integrated smoke control system 1000 according to an embodiment of the present invention may be a moving passage of an elevator, i.e., an elevator hoistway or a vertical duct provided in the front room 200. That is, the integrated smoke control system 1000 according to an embodiment of the present invention may be provided in a building in which the vertical duct 400 is additionally provided in the front room, and in addition, may be provided in a building in which the elevator shaft is used as an inflow passage of outside air to control smoke, in which case no additional vertical passage is provided in the front room.
According to an embodiment of the invention, the elevator 110 associated with the integrated smoke control system 1000 may comprise an emergency elevator or an evacuation elevator.
Specifically, the current law states that emergency elevators should be installed in principle at a place of 31m or more in all high-rise buildings, and may refer to an elevator used as a place for firefighters to perform firefighting activities in the event of a fire.
In addition, the evacuation elevator is mainly installed in a building (super high rise) with 30 floors or more, and may be an elevator for escaping evacuation people when a fire occurs by running only between a specific floor (evacuation floor) where evacuation avoidance places are provided and an evacuation safety floor (upper rise) in order to evacuate occupants safely.
In this regard, the landing of the emergency elevator and the landing of the evacuation elevator are substantially identical in structure and function differently, and thus the integrated smoke control system 1000 according to an embodiment of the present invention is applicable to all the landings of the emergency elevator or the evacuation elevator.
Fig. 2 is a schematic top view of a prior art flue gas control system with a vertical air duct and an automatic pressure differential damper in addition to the front chamber.
Referring to fig. 2, in the conventional smoke control system, a dedicated vertical duct (duct 400) is additionally provided for supplying external air to the front compartment 200. In addition, in order to adjust the air flowing from the dedicated vertical duct 400, an automatic pressure difference damper 410 is used.
However, in the case of the manner of providing the dedicated vertical duct 400, there is a limit in that the entire space area cannot be utilized, and it is almost impossible to additionally provide the dedicated vertical duct 400 in the completed building. In contrast, the integrated smoke control system 1000 according to an embodiment of the present invention has advantages in that it can increase space utilization and can use the structure of the existing building to provide smoke control equipment since the air supply duct 100 is used as a vertical duct.
In addition, the dedicated vertical duct 400 is difficult to set to a wider sectional area than a moving passage of an elevator, i.e., an elevator hoistway, due to its space limitation, and the air volume moves within a limited area of the dedicated vertical duct 400, and thus, the wind speed is high, friction loss is large, static pressure increases, and accordingly, the pressure difference between upper and lower floors within the dedicated vertical duct 400 also becomes severe, in order to supply a constant air volume to all floors of a building, it is required to use an air supply damper of a precisely controlled opening area (opening ratio) at all floors of the building, and the elevator hoistway is used as the integrated smoke control system 1000 according to an embodiment of the present invention of the air supply duct 100, since the sectional area of the elevator hoistway is significantly wider than the dedicated vertical duct 400, when external air moves within the elevator hoistway, the wind speed does not become rapid, and friction loss is reduced, the static pressure is maintained between the upper and lower floors, and the constant air volume can be supplied to the front room 200 of all floors of the building without additional precise control.
In addition, with the conventional automatic pressure difference damper 410, in order to supply a constant air volume to all floors in accordance with a limited area of the dedicated vertical duct 400, it is required to use an air supply damper for precisely controlling an opening area (opening ratio) at all floors of a building, but it is difficult to actively cope with various situations that may occur when a fire occurs by supplying external air to the smoke control area only by using a pressure difference between the smoke control area and the room of each floor, and furthermore, the conventional smoke control system to which the automatic pressure difference damper 410 is applied cannot precisely control the damper provided at each floor in consideration of factors other than the pressure difference between the smoke control area and the room of each floor. Further, since the automatic differential pressure damper 410 performs measurement and judgment of the pressure difference, opening control of the damper, and the like, it is difficult to quickly cope with pressure changes of the front chamber that occur when the fire door provided in the front chamber is opened, and it is difficult to accurately measure pressure changes that occur due to the amount of air leaking from the gaps of the walls between the elevator door and the landing or between the elevator door and the elevator hoistway, and the amount of air leaking from various gaps of the front chamber, and thus there is a problem that the automatic differential pressure damper 410 cannot be precisely controlled to control smoke.
In particular, in the existing smoke control system, if an occupant receives a fire occurrence signal, the occupant enters a panic state and all the occupants of all floors that give an evacuation alarm are simultaneously evacuated multiple times, and at this time, the fire doors 220 of the front chambers 200 of the plurality of floors are opened, but the automatic pressure difference damper is often opened only at the floor where the fire doors 220 of the front chambers are opened, and thus, smoke control performance is lacking.
The air supply fan 20 may be provided at a portion of the air supply duct 100 to supply air outside the building into the air supply duct 100. When an elevator hoistway is used as the air supply duct 100, the air supply fan 20 may be provided at a lower portion of the elevator hoistway, and supply air outside the building into the elevator hoistway, for example. However, in this case, the position where the air supply fan 20 is provided is not limited to the lower portion of the elevator hoistway, and may be provided in an upper portion or an intermediate region of the air supply duct 100 according to an embodiment.
The front room 200 may refer to an area corresponding to a smoke control zone provided at each floor of a building. In addition, the front compartment 200 in the present invention may include a landing for accessing the space between the elevator door 210 of the elevator and the residence 300 or an emergency evacuation stairwell provided in a building. In particular, the front compartment 200 may include a fire door 220 formed in an area adjacent to the residence 300.
Referring to fig. 1 to 5, a case where the front room 200 to which the integrated smoke control system 1000 is applied is a landing for entering and exiting a space of an elevator is mainly described, but the operation and function of the integrated smoke control system 1000 according to an embodiment of the present invention is not limited thereto and may be applied to a case where the front room 200 is an emergency evacuation stairwell as well.
In addition, when the front room 200 is a landing for entering and exiting an elevator, the supply air duct 100 as an external air inflow path may be a moving path of the elevator, i.e., an elevator hoistway, or a vertical duct provided at the landing in addition.
On the other hand, when the front compartment 200 is an emergency evacuation stairwell provided in a building, the air supply passage 100, which is an inflow passage of outside air, may be a vertical pipe provided in the emergency evacuation stairwell.
FIG. 3 is a perspective view of a front chamber with an integrated smoke control system according to an embodiment of the invention.
Referring to fig. 3, a differential pressure sensor 201 for sensing a pressure difference between the front chamber 200 and the residence 300 may be provided at the front chamber 200; and a fire door sensor 202 for sensing whether to open or close the fire door 220 provided in the front compartment; or at least one of the smoke prevention wind speed sensors 203 for sensing the smoke prevention wind speed of the front room 200.
The air supply damper 30 is provided at a predetermined region between the air supply duct 100 and the front chamber 200, and is opened to supply the external air supplied to the air supply duct 100 by the air supply fan 20 to the front chamber 200, or is closed to shut off the inflow of the external air.
According to an embodiment of the present invention, when the vertical duct provided in the front chamber 200 is used as the supply air duct 100, the predetermined area between the supply air duct 100 provided with the supply air door 30 and the front chamber 200 may refer to a predetermined area opened toward the front chamber 200 in the wall surface of the vertical duct corresponding to the boundary between the vertical duct and the front chamber 200.
According to other embodiments of the present invention, when using the moving path of the elevator, i.e., the elevator hoistway, as the supply air duct 100, the predetermined area between the supply air duct 100 provided with the supply air door 30 and the front room 200 may refer to a boundary wall of the elevator hoistway and the front room 200 or a predetermined area of the elevator door 210.
In addition, according to an embodiment of the present invention, the air supply damper 30 may have inherent address information assigned to each air supply damper 30 provided in the building. Further, the air supply damper 30 may include a structure capable of storing information of the control section, the memory, the communication section, and the like and communicating with an external device. Further, when at least a portion of each of the air supply dampers 30 provided in the building is opened or closed, the operation state information and the address information may be transmitted to the integrated control section 40. Here, the address information may refer to data for identifying each of the plurality of air supply dampers 30 provided at each floor by the integrated control section 40, without being limited by a format or a data type.
Further, according to an embodiment of the present invention, the air supply Damper 30 may be a Motorized Damper (MD) including a motor operated by a driving motor to be opened or closed.
According to an embodiment of the present invention, an electric damper (MD) includes a motor; a rotation shaft fixed to the motor; the air door blades are connected with each other through a connecting rod and a connecting rod, and are interlocked with each other to rotate towards the left and right directions respectively when the rotating shaft is driven; a louver (for example, may be formed of a perforated plate or a wire net) is formed with a plurality of louver blades fixedly supported at the rear of the damper blade, concealing the inside while protecting various parts inside from touch by a person's hand, but is not limited thereto. As another example, the electric damper (MD) is formed by a motor, an air duct frame, and a flat plate for opening or closing an opening of the air duct frame, and the opening or closing operation is performed by the back-and-forth movement of the flat plate, so that the amount of flue gas control air supplied to the flue gas control area (front chamber) is adjusted. For convenience of explanation, the electric damper including the damper blade is referred to as a damper blade type electric damper, and the electric damper that performs an opening or closing operation by a forward and backward movement of the flat plate is referred to as a flat plate type electric damper.
Accordingly, the fact that at least a portion of the supply air damper 30 is opened means that the ratio of the external air supplied from the supply air duct 100 to the front chamber 200 varies according to the rotation angle (inclination) of the damper blade in the case of the wing type electric damper, and similarly, the ratio of the external air supplied from the supply air duct 100 to the front chamber 200 varies according to the degree of forward and backward movement of the flat plate in the case of the flat plate type electric damper.
For example, the electric damper is opened by 100%, which may refer to a case where in the case of the wing type electric damper, the damper blade is rotated (tilted) to the maximum so that the sectional area of the external air supplied from the supply air duct 1000 passing through the electric damper is the maximum. Also, in the case of the flat plate type electric damper, it may refer to a case where the flat plate is moved forward at most so that the sectional area through which the external air supplied from the air supply duct 100 flows in through the space partitioned from the duct frame when the flat plate is moved forward is maximized. In contrast, the electric damper is closed (in other words, opened by 0%), which may refer to a state in which the damper blade is kept closed (in a non-rotated state) at the time of the wing type electric damper in order to prevent the inflow of the external air from the supply air duct 100 to the front chamber 200, the flat plate does not advance from the duct frame at the time of the flat plate type electric damper, and there is no gap between the flat plate and the duct frame through which the external air passes. In addition, according to an embodiment of the present invention, in order to properly adjust the wind speed, the wind volume, etc. of the external air flowing into the front chamber 200, the rotation angle of the damper blade of the wing type electric damper may be adjusted, and the degree of forward and backward movement of the flat plate type electric damper may be adjusted.
Here, the integrated control unit 40 controls the opening degree of the air supply damper 30, and it is understood that at least one of the air volume and the air velocity of the external air supplied from the air supply duct 100 to the front compartment 200 is adjusted.
As for the amount of the external air supplied to the front compartment 200, the integrated control part 40 may control the opening degree of the air supply damper 30 in consideration of at least one of the amount of the air discharged from the smoke control zone through the entrance/exit door of the front compartment 200, the fireproof door 220, the window, the slit of the elevator door 210, etc., i.e., the leakage amount, or the amount of the air further supplied to the front compartment 200 according to the opening/closing of the fireproof door 220 opened or closed during the evacuation of occupants, i.e., the supplementary amount.
In addition, as for the wind speed of the external air supplied to the front compartment 200, the integrated control part 40 may control the opening degree of the air supply damper 30 in consideration of the lowest air speed, i.e., the smoke prevention wind speed, which is the air speed that blocks the smoke of the fire chamber that would flow into the front compartment 200 when the fireproof door 220 is temporarily opened and the air pressure of the front compartment 200 is instantaneously reduced. For example, the smoke-proof wind speed may be decided in the range of 0.5 to 0.7m/s with reference to national fire safety standards and the like.
The integrated control part 40 may receive a fire detection signal from the fire detector 10 and control the opening and closing of the air supply damper 30 of each floor of the building based on the fire detection signal.
Fig. 4 is a diagram for explaining a state in which air supply dampers of all floors of a building are opened by an integrated smoke control system according to an embodiment of the present invention at the time of a fire.
Referring to fig. 4, the integrated control part 40 according to an embodiment of the present invention may control the air supply damper 30 of all floors of a building to be opened when a fire detection signal is received from the fire detector 10.
For this, the gap between the landing elevator door 210 and the front room 200 or the supply air duct 100 is allowed to be 10mm at maximum, but is mainly set to be a gap of about 5mm in practice. When air flows from the supply air duct 100 into the front chamber 200 through these door slits of each floor or, conversely, when air is discharged from the front chamber 200 to the supply air duct 100, the pressure rises by 1Pa every time 1/100000 of the respective volume of the front chamber 200 or the supply air duct 100 is supplied. That is, even if air is supplied from any direction, the space between the supply air duct 100 and the front chamber 200 can be regarded as an open state from the pressure aspect. Accordingly, the electric damper (MD) is provided to the air supply damper 30 of each floor instead of the automatic differential pressure damper 410 applied to the conventional smoke control system, and the integrated control unit 40 can control the air supply damper 30 of all floors to be opened in the event of a fire, so that the smoke can be controlled promptly and rapidly, as compared with the case of using the automatic differential pressure damper 410 that is repeatedly opened and closed according to the fire occurrence signal. Therefore, in the case of a fire, the pressure difference between the smoke control area and the room (for example, the pressure difference of 50 Pa) can be maintained rapidly and continuously to supply air and pressure, and thus, smoke prevention wind can be pressurized in the direction of the fire door immediately when the fire door is opened. In addition, it is difficult to rapidly cope with pressure changes of the front chamber, which are generated when the fire door provided in the front chamber is opened, due to the measurement and judgment of the pressure difference, the opening control of the damper, etc., which occur due to the use of the automatic pressure difference damper 410, and it is difficult to accurately measure pressure changes, which are generated due to the amount of air leaking from the gaps of the wall between the elevator door and the landing or between the elevator door and the elevator hoistway, and the amount of air leaking from various gaps of the front door, and it is difficult to precisely control the automatic pressure difference damper 410 to control the smoke, and these disadvantages can be solved by maintaining the state of the electric air supply damper 30 that is opened at all floors when a fire occurs.
According to an embodiment of the present invention, when a fire detection signal is received from the fire detector 10, the integrated control part 40 may control the air supply dampers 30 of all floors to be opened maximally (i.e., to be opened 100%), so that the smoke can be immediately and rapidly controlled to the front room 200. Here, controlling the supply air damper 30 to be opened maximally may mean controlling the rotation angle (opening angle) of the damper blade of the airfoil damper to be maximized as described above.
As another example, the integrated control part 40 may receive a fire detection signal and information related to the intensity of occurrence of a fire from the fire detector 10, determine a driving ratio based on the intensity of occurrence of a fire, and control the opening degree of the air supply damper 30 based on the determined driving ratio. For example, when the intensity of fire occurrence received by the integrated control part 40 exceeds a preset threshold intensity and is recognized as an emergency, the integrated control part 40 may control the air supply damper 30 to be opened at a maximum driving ratio (100%). As another example, when the intensity of fire occurrence received by the integrated control part 40 is less than or equal to a preset threshold intensity, the integrated control part 40 may control the air supply damper 30 to be opened at a preset driving ratio. At this time, according to an embodiment, the preset threshold intensity may be differently set to a plurality of values (levels), and accordingly, the driving ratio (opening ratio) of the air supply damper 30 may also have various values according to circumstances.
Fig. 5 is a diagram for explaining a state in which air supply dampers of a fire occurrence floor and preset upper and lower predetermined floors are opened at a higher driving ratio than air supply dampers of other floors by an integrated smoke control system according to an embodiment of the present invention at the time of a fire.
Referring to fig. 5, the integrated control part 40 according to an embodiment of the present invention may receive information related to a location of occurrence of a fire from the fire detector 10, and may control the air supply damper 30 of the floor where the fire occurs and the upper and lower predetermined floors preset for the floor where the fire occurs to be opened at a higher driving ratio than the air supply dampers 30 of other floors.
Here, the upper and lower predetermined floors preset for the fire occurrence floor may be determined based on information associated with the intensity of fire occurrence received from the fire detector 10. For example, the number of the upper and lower predetermined floors when the intensity of the fire occurrence is high may be determined to be greater than the number of the upper and lower predetermined floors when the intensity of the fire occurrence is small.
Further, according to an embodiment of the present invention, the integrated control part 40 may control the air supply damper 30 of the fire occurrence floor and the upper and lower predetermined floors preset for the fire occurrence floor to be opened at least in part and close the air supply damper 30 of the other floors.
As another example, the integrated control unit 40 controls the opening of the air supply dampers 30 on all floors in the building, and at this time, controls the opening of the air supply dampers 30 on the fire occurrence floor and the upper and lower predetermined floors preset for the fire occurrence floor to be larger than the opening of the air supply dampers 30 on the other floors. That is, for example, the integrated control unit 40 may control the air damper 30 of the fire occurrence floor and the upper and lower predetermined floors preset for the fire occurrence floor to be opened at a drive ratio of 80% and control the air supply damper 30 of the other floors to be opened at a drive ratio of 40%.
As another example, the integrated control unit 40 may control the opening of the air supply damper 30 of the floor where the fire occurs, and then control the opening of the air supply damper 30 of the preset upper and lower floors in consideration of the information related to the additional fire situation received from the fire detector 10.
As another example, the integrated control part 40 may sense address information and operation states of the dampers, and control the air supply damper 30 provided on a floor where smoke or fire occurs or the air supply damper 30 installed on a floor of a preset floor number adjacent to the corresponding floor to be preferentially opened.
Further, the integrated control part 40 may determine whether each of the air supply dampers 30 provided in the building is operating normally based on the operation state information and the address information received from the air supply dampers 30.
For example, the integrated control unit 40 may transmit an opening control signal or a closing control signal corresponding to a specific driving ratio to the air supply damper 30 of each floor in accordance with a preset monitoring period, and in response thereto, receive operation state information and address information from the air supply damper 30 of each floor, and determine whether the air supply damper 30 of each floor is accurately opened or closed in accordance with the control signal of the integrated control unit 40. That is, the integrated smoke control system 1000 according to an embodiment of the present invention may provide a self-diagnosis function of periodically confirming whether the air supply damper 30 is abnormal based on address information and operation state information.
Further, according to an embodiment of the present invention, it is characterized in that the integrated control part 40 can be switched to a manual operation mode so that the opening or closing of the air supply damper 30 provided at each floor of the building can be individually controlled. For example, the integrated control unit 40 or the manager operation panel is connected to a signal connection line and a button for operating the opening and closing of each air supply damper 30, and each air supply damper 30 can be manually operated by a button operation.
That is, when the integrated control part 40 is switched to the manual operation mode, the manager or the firefighter can differentially open or close the air supply damper 39 provided at each floor in consideration of various situations.
Further, the integrated control section 40 may control a motor of the electric Damper to control opening or closing of the electric Damper (MD), i.e., the air supply Damper.
Further, according to an embodiment of the present invention, the integrated control part 40 may receive a sensing result of at least one of the differential pressure sensor 201, the fire door sensor 202, or the smoke prevention wind speed sensor 203. At this time, the integrated control part 40 may control the opening or closing of the air supply damper 30 according to at least one of the pressure difference between the front room 200 and the residence 300 sensed by the pressure difference sensor 201, whether the fire door 220 is opened or closed sensed by the fire door sensor 202, or the smoke prevention wind speed value in the front room 200 sensed by the smoke prevention wind speed sensor 203.
According to an embodiment of the present invention, the integrated control part 40 may receive the pressure difference between the front room 200 and the residence 300 sensed by the pressure difference sensor 201 from the pressure difference sensor 201 to control the opening degree of the air supply damper 30 of the corresponding floor such that the pressure difference between the front room 200 and the residence 300 has a range of 40Pa to 60 Pa.
Further, according to an embodiment of the present invention, the integrated control part 40 may receive whether to open or close the fire door 220 sensed by the fire door sensor 202, and control the opening degree of the air supply damper 30 according to whether to open or close the fire door 220 to adjust at least one of the air volume and the air speed of the outside air supplied to the front room 200 of the corresponding floor.
Further, according to an embodiment of the present invention, the integrated control part 40 may receive the smoke preventing wind speed value in the front chamber 200 sensed by the smoke preventing wind speed sensor 203 to control the opening degree of the air supply damper 30 such that the smoke preventing wind speed value in the front chamber 200 is in the range of 0.5 to 0.7 m/s.
Further, according to an embodiment of the present invention, the integrated control part 40 may control at least one of the supply air volume and the supply air speed of the supply air fan 20.
