Description

Apparatus and method for controlling window opening and closing based on differential pressure for smoke control area {APPARATUS AND METHOD FOR CONTROLLING WINDOW IN VENTILATION AREA BASED ON DIFFERENTIAL PRESSURE}

The present application relates to a window opening/closing control device and method based on differential pressure for a smoke control area.

Smoke control technology determines the fire growth time and controls the movement of smoke and clean, safe air inside the building to ensure safety from smoke generated when a fire breaks out in a building. Specifically, since the flow of clean air and smoke moves from high pressure to low pressure, controlling the physical flow of air and smoke can be said to control the pressure inside the building.

A smoke control facility is a system that exhausts smoke or toxic combustion gases in the event of a fire using mechanical methods such as a blower or exhaust. These smoke control facilities are largely divided into smoke control facilities that prevent smoke from entering the pressurized space by pressurizing the space between physical barriers with a blower, or smoke ventilation facilities that forcibly expel smoke that has entered the room through an exhaust. It can be divided into:

In particular, conventional smoke control equipment by pressurizing supply air installs a dedicated vertical air duct (duct) and a differential pressure damper to pressurize smoke control areas such as staircases, auxiliary rooms, and platforms, or installs a supply air duct (duct) in the hoistway, which is the moving passage of the elevator. It is designed in a way that it can be used as a

In this regard, the conventional damper for pressurizing the supply air is mainly installed to operate to maintain a predetermined level (for example, a differential pressure of 50 Pa) by a differential pressure sensor that measures the differential pressure between the smoke control area and the indoor. Since fresh air is supplied to the smoke control area only depending on the floor smoke control area and the differential pressure inside the building, there was a limitation in supplying air to the platform (accessory room) by actively responding to various situations that may occur in the event of a fire.

In addition, in the case of a building in which windows are installed for ventilation purposes in smoke control areas such as auxiliary rooms where supply air is pressurized, an automatic closing device may be provided to close the windows to pressurize the supply air in the event of a fire. This conventional automatic closing device allows the operator to manually open and close the window in normal times, but only has the function of automatically closing the window in the event of a fire, and is limited to the function of automatically closing the window in the event of a fire. A window opening/closing control device with the function of controlling overpressure considering the pressure distribution has not been introduced.

The technology behind this application is disclosed in Korean Patent Publication No. 10-1316098.

In addition, the collection unit includes a calculation result obtained by subtracting the second pressure measured indoors from the first pressure measured in the smoke control zone in a state in which air supply pressure is performed on the smoke control zone when a fire occurs in the building. The differential pressure information can be obtained.

Additionally, the control unit may control the closed window to be opened if the calculation result is greater than or equal to a preset threshold pressure.

Additionally, the control unit may determine at least one of an opening level of the window and an opening time of the window based on the difference between the calculation result and the limit pressure.

Additionally, the controller may re-close the window based on the differential pressure information collected after the window is controlled to be opened.

In addition, a differential pressure-based window opening/closing control device for a smoke control area according to an embodiment of the present application includes an air supply damper disposed for the smoke control area, an inverter that controls the operation of a blower for smoke control of the building, and a connection with the blower. It may include a communication unit that receives the differential pressure information from at least one of the composite dampers.

Additionally, the collection unit may obtain the differential pressure information from the communication unit.

Additionally, the collection unit may obtain the differential pressure information from a measured value of a differential pressure sensor provided in the window opening/closing control device.

Additionally, the communication unit may receive the fire detection signal from a fire detector that detects whether a fire has occurred in the building and generates a fire detection signal.

Additionally, the control unit may close the window based on the fire detection signal.

Meanwhile, a differential pressure-based window opening/closing control method for a smoke control zone according to an embodiment of the present application includes obtaining differential pressure information between a smoke control zone provided in a building and an indoor location located adjacent to the smoke control zone, and adding the differential pressure information to the smoke control zone. Based on this, it may include the step of opening a window installed in the smoke control zone to discharge the air in the smoke control zone to the outside when opened.

In addition, the obtaining step is a calculation result of subtracting the second pressure measured indoors from the first pressure measured in the smoke control zone in a state in which air supply pressure is performed on the smoke control zone when a fire occurs in the building. The differential pressure information including can be obtained.

Additionally, in the opening step, if the calculation result is higher than a preset threshold pressure, the window in a closed state may be controlled to be opened.

It can be understood as broadly applicable to communication systems.

In the description of the embodiment of the present application, the window opening/closing control device 100 is individually provided for the smoke control area 2 on each floor of the building to control the opening and closing of the window 11 installed in the smoke control area 2 on each floor. It may be provided. As another example, the window opening/closing control device 100 controls the opening and closing of the windows 11 installed in the smoke control area 2 of each floor from a remote location, as shown in FIG. 1, in a specific area (e.g., control It may be provided in a facility, basement, etc.).

The window opening/closing control device 100 may receive a fire detection signal from a fire detector (not shown) that detects whether a fire has occurred in the building and generates a fire detection signal. Additionally, the window opening/closing control device 100 may close the window 11 based on a fire detection signal.

In other words, when the window opening/closing control device 100 disclosed herein detects the occurrence of a fire in the building, it prevents smoke from entering the smoke control area (2), which is a pressurized space, by pressurizing the supply air to the smoke control area (2). To ensure safe evacuation of occupants in the building, a window is provided primarily in the smoke control area (2) to prevent the outside air supplied by the blower (301) from escaping through the vertical airflow or the elevator shaft as a supply airflow. If (11) is previously open, control can be performed to close the window (11).

Meanwhile, in the description of the embodiment of the present application, the window opening/closing control device 100 is capable of independently controlling whether each window 11 of the smoke control area 2 provided on each floor in the building is opened or closed, but a fire detection signal is generated. Close to the point in time, the windows of the smoke control area (2) on all floors are controlled to be closed at once, and the air supply damper (200) provided in the smoke control area (2) on each floor is opened to pressurize the air supply to the smoke control area (2). You can control it to start.

Afterwards, the window opening/closing control device 100 may obtain differential pressure information between the smoke control area 2 provided in the building and the indoor area 30 located adjacent to the smoke control area 2.

Specifically, the window opening/closing control device 100 controls the first pressure (P Differential pressure information including a calculation result obtained by subtracting the second pressure (P ₂ ) measured indoors from ₁ ) can be obtained.

Additionally, the window opening/closing control device 100 may open the window 11 installed in the smoke control zone 2 to discharge air within the smoke control zone 2 to the outside when opened based on the acquired differential pressure information. Specifically, according to an embodiment of the present application, the window opening/closing control device 100 is a calculation result according to the first pressure (P ₁ ) and the second pressure (P ₂ ) (i.e., the first pressure (P ₁ ) If the pressure difference minus the pressure (P ₂ ) is greater than or equal to a preset limit pressure, the closed window 11 can be controlled to be opened.

Meanwhile, according to an embodiment of the present application, the window opening/closing control device 100 receives a measured value reflecting the first pressure (P ₁ ) of the smoke control zone (2) using a first pressure sensor (not shown) installed in the smoke control zone (2). city), and a measured value reflecting the second pressure (P ₂ ) of the indoor 30 is received from a second pressure sensor (not shown) installed at at least one location of the indoor 30 to determine each measured value. By subtracting the pressure and comparing it with the preset limit pressure (limit pressure deviation), it is determined whether the smoke control area (2) is overpressured, and if it is determined that the smoke control area (2) is overpressured, the window (11) of the smoke control area (2) is opened. It may be.

As another example, the window opening/closing control device 100 obtains real-time measurements of the pressure in the smoke control area 2, and the fire door (not shown) interposed between the smoke control area 2 and the indoor space 30 is opened. By retaining the previously measured pressure measurement value of the smoke control area (2) as a reference measurement value, the real-time measurement value is substituted as the first pressure (P ₁ ), and the previously held reference measurement value is corresponded to the pressure information of the indoor (30). In place of the second pressure (P ₂ ), differential pressure information including the calculation result of subtracting the second pressure (P ₂ ) from the first pressure (P ₁ ) can be obtained.

In this regard, after the occurrence of a fire, outdoor air is continuously supplied to the smoke control area (2) by the air supply damper 200, etc. due to the pressurization of the air supply to the smoke control area (2), so that the smoke control area (2) is compared to the indoor area (30). The air pressure may be relatively excessively high (in other words, an overpressure state), and in this overpressure state, occupants attempting to evacuate by entering the smoke control area (2) from the indoors (30) may enter the indoors (30) and the smoke control area (2). ) Considering that an unexpected dangerous situation may occur, such as failure to open the fire door between If continuous monitoring determines that the smoke control area (2) is overpressurized, the window (11) of the smoke control area (2) is opened to allow some of the air in the smoke control area (2) to escape through the open window (11). Thus, the overpressure condition in the smoke control area (2) can be resolved.

Meanwhile, according to an embodiment of the present application, the window opening/closing control device 100 may be controlled to selectively open only the windows 11 of the smoke control zone 2 on the floor where overpressure occurs based on differential pressure information for each floor. In other words, the air supply was pressurized after the window 11 was closed by the fire signal, but the difference between the first pressure (P ₁ ) and the second pressure (P ₂ ) was determined to be within the limit pressure (in other words, the floor Windows 11 in smoke control areas (2), etc.) that are determined not to be overpressurized may not be opened.

In addition, according to an embodiment of the present application, the window opening/closing control device 100 determines whether the smoke control zone 2 is overpressured and whether the opening control of the window 11 is necessary based on the obtained differential pressure information. The 'threshold pressure' may be variable considering the number of floors of each smoke control zone 2, the distance from the blower 301, the distance from the fire floor, the distribution of occupants on each floor, etc.

For example, when the blower 301 for pressurizing supply air is installed adjacent to the top floor of a building as shown in FIG. 1, the closer the floor to the blower 301 (in other words, the upper floor), the more likely it is that the smoke control zone will be removed by pressurizing the supply air. Considering that (2) can easily reach an overpressure state, the window opening/closing control device 100 sets the limit pressure set for the smoke control area 2 located on the upper floor relatively strictly (in other words, sets it to a small value). ), but is not limited to this.

As another example, the window opening/closing control device 100 has the possibility of opening the fire door of the floor while the occupants are evacuating in the smoke control area 2 of the floor adjacent to the fire floor, according to fire floor information identified by a fire detection signal, etc. Considering that this is high, the limit pressure set for the smoke control zone 2 may be set relatively strictly (in other words, set to a small value) for the floor adjacent to the fire floor, but it is not limited to this.

As another example, the window opening/closing control device 100 operates according to fire intensity information identified by a fire detection signal, etc., when the fire intensity is stronger than a critical level (for example, the fire occurrence area is greater than a preset critical area). (e.g., when it is determined that a fire occurred in a location close to the location of hazardous substances present in the building), there is sufficient high pressure in the smoke control area (2) to prevent smoke from entering the smoke control area (2) from the interior (30). The above-mentioned limit pressure can be adjusted to be relatively high so that this maintained condition is preferentially satisfied.

In addition, according to an embodiment of the present application, the window opening/closing control device 100 operates the window 11 based on the calculation results of the first pressure (P ₁ ) and the second pressure (P ₂ ) and the deviation of the preset limit pressure. At least one of the opening level and the opening time of the window 11 can be determined.

In this regard, according to an embodiment of the present application, the window opening/closing control device 100 operates in the smoke control zone 2 as the calculation result of the first pressure (P ₁ ) and the second pressure (P ₂ ) greatly exceeds the limit pressure. By determining that there is a need to quickly resolve the overpressure condition, at least one of the opening level of the window 11 and the opening time of the window 11 may be adjusted upward.

For reference, the opening level of the window 11 refers to a type (e.g., hinge type) window 11 in which the window 11 opens while rotating around a rotation axis where one end is provided adjacent to the other end. In this case, the rotation angle of the window may correspond to the opening level. As another example, in the case of a type (eg, flat type) window 11 that is opened by advancing the window 11 as a whole from the window frame structure, the degree of advancement of the window may correspond to the opening level.

Additionally, the window opening/closing control device 100 may control the window 11 to be reclosed based on differential pressure information collected after the window 11 is controlled to be opened based on the differential pressure information. In other words, the window opening/closing control device 100 determines that the smoke control area 2 has reached an overpressure state and controls the window 11 to be opened, after which the overpressure condition in the smoke control area 2 is resolved and the smoke control system 100 controls the window 11 to open. If it is determined that the condition of zone 2 has changed to maintain the appropriate level of differential pressure, the window 11 can be closed again to induce the supply air pressurization process to maintain the appropriate level of differential pressure to continue.

In addition, according to an embodiment of the present application, when it is determined that the window 11 of the smoke control zone 2 needs to be opened based on the differential pressure information, the window opening/closing control device 100 controls the opening of the window 11 and By lowering the degree of opening of the air supply damper 200 provided to pressurize the supply air in the smoke control zone 2, the control can be performed to further promote the resolution of the overpressure condition in the smoke control zone 2.

In addition, according to an embodiment of the present application, when the window opening/closing control device 100 determines that the smoke control zone 2 is in an overpressure state based on the differential pressure information acquired after the start of the supply air pressurization, it primarily performs the smoke control operation. The opening rate of the supply air damper 200 of the zone 2 is controlled, and even when the supply air intensity is changed downward so that the overpressure of the smoke control zone 2 can be relieved through the control of the supply air damper 200, the smoke control zone is still maintained. (2) When the differential pressure inside the indoor area 30 exceeds a preset range (i.e., a preset limit pressure), the window 11 of the smoke control area 2 may be controlled to be opened secondarily.

To this end, the window opening/closing control device 100 primarily controls the opening/closing and opening rate of the air supply damper 200 in response to the overpressure state identified while the window is closed, and then the air supply damper 200 controls the air supply damper 200. It is possible to determine again whether the pressure difference between the smoke control area 2 and the indoor area 30 has changed to a state that satisfies the preset limit pressure. If the pressure difference is determined to still exceed the preset limit pressure range based on the re-judgment result of the window opening/closing control device 100, the window opening/closing control device 100 may control the window 11 to be opened. there is.

Meanwhile, according to an embodiment of the present application, the air supply damper 200 is a vertical air supply passage, which is an inflow passage of air outside the building for pressurizing the supply air, which is a passage of the elevator 1000, or a vertical ventilation shaft provided in each smoke control zone 2. In the case of ducts, they may be provided at corresponding positions.

In this regard, Figure 2 is an exemplary plan view of a building having a structure in which a separate vertical airflow is provided in the smoke control area, and Figure 3 is a diagram showing a smoke control system that utilizes the hoistway as a supply airflow to the smoke control area. This is an exemplary drawing showing the floor plan of a building.

In this regard, according to an embodiment of the present application, the window opening/closing control device 100 measures the first pressure (P ₁ ) included in the differential pressure information to determine whether the window 11 needs to be opened when the air supply is pressurized. The location can be determined more precisely based on the type of supply air draft installed in the smoke control area (2).

In addition, according to an embodiment of the present application, the window opening/closing control device 100 includes an air supply damper 200 disposed with respect to the smoke control area 2, and an inverter ( 310) and the complex damper 320 associated with the blower 301, differential pressure information for determining whether the window 11 needs to be opened when the air supply is pressurized may be obtained using various wired or wireless communications.
