Description

Smoke control system using communication type vestibule damper { SMOKE-CONTROL SYSTEM USING COMPOSITION DAMPER }

The present invention relates to a smoke control system, and more specifically, to a smoke control system using a communication type vestibule damper.

Recently, as cities have become more sophisticated and integrated, buildings have rapidly become larger, higher-rise, and more complex, and the need for effective fire measures for human safety is urgently needed.

In particular, the importance of smoke control systems for controlling smoke, which causes great disruption to evacuation and fire-fighting activities in the event of a fire and poses the greatest threat to human safety, is increasingly being highlighted.

Therefore, in the case of smoke control equipment installed on special evacuation stairs and emergency elevator platforms, there is a total actual research area consisting of an escape staircase and an annexed room in front of the indoor and living room entrance door, and in the event of a fire, smoke flows into the total actual research area equipped with an escape staircase. Smoke control equipment will be installed to increase the air pressure in the entire actual research area to prevent it from coming out.

In the event of a fire, when the air pressure in the actual research area is maintained at a higher pressure than the air pressure in the indoor and living room where the fire occurred, the smoke from the living room where the fire occurred cannot escape into the actual research area where the escape stairs are provided. This prevents smoke from spreading throughout the building, prevents evacuees from suffocating by smoke, and secures smoke-free escape stairs.

Meanwhile, Registered Patent Publication No. 10-2248807 (announced on May 4, 2021, hereinafter referred to as Patent Document 1) is a blower installed to introduce air from outside the building into the hoistway or exhaust air from the hoistway to the outside of the building, In a hoistway-type smoke control system in which an automobile pressure supply damper is installed on each floor of a building to control the air pressure in the hoistway, allowing the building's hoistway to be used as a smoke control duct, the automobile pressure supply damper escapes from the inside of the side wall of the hoistway. A hoistway-type smoke control system equipped with a safety net to prevent the automobile pressure supply damper from falling into the hoistway is being disclosed.

In Patent Document 1, the safety net is fixed to the side wall to prevent the damper from coming off, but in fact, the technology for fixing the safety net to the side wall or the technology for fixing the damper to the side wall is to install a bolt by inserting a bolt into the side wall, thereby ensuring a fixed installation of the safety net. is questionable, and ultimately, even if a safety net is excluded, a means to prevent the damper from breaking away is required.

In addition, Registered Patent Publication No. 10-2091681 (announced on March 16, 2020, hereinafter referred to as Patent Document 2) is a technology implemented so that the hoistway can be used as a windway, unlike the common method of pressurizing the elevator platform with a separate dedicated airway. It relates to a supply pressurization smoke control system using a hoistway as a vertical duct, and includes an automatic differential pressure damper installed on the wall of the hoistway to supply and pressurize air from the hoistway into the indoor space.

Patent Document 2 can supply air through a hoistway in which an elevator moves without a separate duct for space utilization.

However, in Patent Document 2, since an elevator exists and moves in the hoistway, which is a vertical duct, the air flow path changes by the elevator, the pressure of the supplied air is not constant and unstable, and the smoke control effect may also be unstable.

In addition, this inconsistent smoke control effect may cause damage to people by preventing them from escaping from the building.

The smoke control system described in Patent Document 1 or 2 is a technology to increase smoke control efficiency and effectiveness, but in modern high-rise buildings, Patent Document 1 or 2 is provided on each floor, so equipment or systems that can control it more effectively This is needed.

The composite damper unit 130 is provided at one end of the duct unit 110, but is adjacent to the blowing unit 120 and is preferably positioned further away from the ventilation hole than the blowing unit 120.

The composite damper unit 130 is capable of controlling the amount of air introduced by the blower unit 120 and passing through the composite damper unit 130. By opening the composite damper unit 130, external air can be moved to the duct unit 110 by the blowing unit 120, and in detail, the amount of air movement, that is, the wind volume, can be adjusted depending on the degree of opening and closing. there is. In other words, the composite damper unit 130 receives sensing values such as air pressure or air flow rate transmitted from a sensor (not shown) of the floor where the front room damper unit 140, which will be described later, is installed, and compares it with a predetermined pressure. By opening and closing according to the user's intention or predetermined settings, the amount of air flowing into each floor of the building can be controlled.

Referring to Figures 2 and 3, the composite damper unit 130 may include a composite damper frame 131 and composite damper louver blades 132.

The composite damper frame 131 may be formed in a square shape, but this is only an example and the composite damper frame 131 may have various shapes depending on the manufacturer's selection.

The composite damper louver blades 132 may be provided inside the composite damper frame 131. The composite damper louver blades 132 can adjust the amount of air flowing into the duct portion 120 by rotating to open and close.

You can try to introduce air. For example, if the building user determines that the air pressure in the entire actual research area 10 of the floor on which it is located is lower than atmospheric pressure and feels uncomfortable, he or she operates the manual angle adjustment motor 134 to move the entire actual research area 10 to the actual research area 10. This allows air to flow in.

For reference, it is preferable that the predetermined pressure setting value of the entire actual research area 10 is 50 Pa. For example, if the air pressure in the entire actual research area 10 detected by the sensor is judged to be overpressure exceeding 50 Pa, the air in the entire actual research area 10 may be exhausted to the outside through an exhaust port (not shown), and the entire actual research area 10 may be discharged to the outside. The air supplied to the research area 10 can be blocked or the amount of air can be reduced. Therefore, the user can set the air pressure range of the entire actual research area 10 in advance through the control unit 200 or the disaster prevention room unit 220, which will be described later.

In other words, the front room damper louver wings 142 can prevent overpressure or differential pressure in the front actual research area 10 of the corresponding floor. When the fire door is opened in the event of a fire, the amount of air flowing into the entire actual research area from the duct part 110 can be adjusted by rotating to supply the amount of air necessary to maintain the smoke-retardant wind speed in the open floor and the differential pressure in the non-open floor.

The vehicle pressure motor 143 can selectively measure the air pressure or atmospheric pressure of the entire actual research area 10 through a sensor (not shown). The vehicle pressure motor 143 is electrically connected to the external control unit 200 and can receive commands. The automobile pressure motor 143 can open and close the plurality of front chamber damper louver blades by rotating them. The vehicle pressure motor 143 is a terminal electrically connected to the switch 143a that turns the power supply on or off by selectively pressurizing it, the vestibule damper louver blade 142, and the communication relay unit 150.

You can.

The front chamber damper unit 140 may further include a sensor (not shown). The sensor is installed in the external air inflow unit 100 to detect the air pressure value or air flow rate value of the entire actual research area 10, and controls the air pressure value and air flow rate value to the control unit 200, which will be described later. It can be transmitted to the unit 200 or transmitted to an external unit, that is, the disaster prevention room unit 220. At this time, the sensor can transmit the sensed air pressure value or air flow rate value to another electronic device through the communication relay unit 150 or communicate wirelessly or wired with the electronic device to receive commands from the electronic device. The air pressure and air flow rate values detected by the sensor can be displayed so that the user can visually check them. For example, by providing a display through the screen of the user's or manager's mobile phone or server, the user or manager can check the degree of air pressure or flow rate in the entire actual research area 10 in numbers or graphs.

In addition, although not shown in the drawing, one embodiment of the present invention may include an air pressure differential pipe (not shown) in the building 1. One end of the air supply differential pressure pipe may be connected to the vestibule damper unit 140, specifically the sensor, and the other end may be connected to the room 30. The air pressure differential pipe can communicate with the duct part 110 and the room 30, and the sensor can detect the air pressure in the room 30. At this time, the sensor can detect the air pressure of the entire actual research area 10 based on the air pressure of the indoor 30 and calculate the difference between the air pressure of the indoor 30 and the air pressure of the entire actual research area 10.

The communication relay unit 150 may be installed in a part of the building 1, may be installed in the composite damper unit 130, or may be placed in the disaster prevention room 220, which will be described later.

The composite damper motor control unit 210 receives the air pressure value or air flow rate value of each floor from sensors (not shown) provided in each actual research area 10 on all floors of the building 1 through the communication relay panel 150. It can be delivered through. In addition, the composite damper motor control unit 210 can receive the air pressure value or air flow rate value of any three floors set by the user from the sensor.

The composite damper motor control unit 210 can control the blower unit 120, the composite damper unit 130, and the front room damper unit 140 so that the front actual research area 10 maintains a predetermined pressure. Also, at this time, the user can control the blower unit 120, the composite damper unit 130, and the front chamber damper unit 140 by directly manipulating the composite damper motor control unit 210.

For reference, if the detected value of the air pressure in the entire actual research area 10, that is, the pressure value, is outside the range of the predetermined pressure value, the user operates the composite damper motor control unit 210 or controls it from the disaster prevention room unit 220. A signal is sent to the composite damper unit 130 to automatically adjust the opening and closing of the composite damper louver blades 132 of the composite damper portion 130 until the air pressure in the entire actual research area 10 falls within the range of the predetermined pressure value.
