Description

적외선 차압 감지 장치{Apparatus For Sensing A Pressure Gap Using An Infrared rays}Apparatus For Sensing A Pressure Gap Using An Infrared rays}

본 발명은 제연구역의 차압을 감지하여 제연구역으로 공기를 인입시키는 댐퍼를 제어하기 위한 차압 감지 장치에 관한 것이다.The present invention relates to a differential pressure sensing device for controlling a damper for sensing the differential pressure in the ventilation zone to draw air into the ventilation zone.

국내 소방법상 규정에 의하면, 건물 화재 시 거주자를 연기로부터 보호하기 위하여 일정면적의 제연구역을 피난계단의 전실에 형성하도록 하고 있다. 또한, 제연구역내 압력을로 유지하도록 하므로써 화재 실에서 발생된 연기가 제연구역내로 침투하지 못하도록 하여, 제연 구역을 거쳐 피난 계단으로 거주자가 안전하게 탈출할 수 있도록 하고 있다.According to the national fire law regulations, in order to protect the occupants from smoke in the event of building fires, a ventilation area of a certain area is to be formed in all rooms of the evacuation stairs. In addition, the pressure in the By keeping it in place, the smoke generated from the fire room is not allowed to penetrate into the ventilation area, so that residents can escape safely through the ventilation area to the evacuation stairs.

한편, 상기한 바와 같은 내부 가압 방식에 의한 제연 시스템은, 연기 화재시에 특정 장치(예를 들어, 자동으로 동작되는 옥내 감지기 및 제연구역에 설치된 수동으로 동작되는 댐퍼)에 의한 화재 신호가 발생되면, 수신기는 신호를 받아 댐퍼, 송풍기, 출입문에 설치된 제연 도어 해정기를 작동시키게 되고, 제연구역에 연결된 열려있는 모든 출입문이 일제히 닫히고 댐퍼개구율을 자동 조절하므로써 제연구역과 옥내(화재실)의 차압을이내로 유지한다.On the other hand, in the above-described internal pressure control system of the dehumidification system, when a fire signal is generated by a specific device (e.g., an indoor detector that is automatically operated and a manually operated damper installed in the ventilation area) during the smoke fire. The receiver receives the signal to operate the damper, the blower, and the dehumidifier door installed in the door, and all the open doors connected to the ventilation area are closed at the same time and the damper opening rate is automatically adjusted to reduce the differential pressure between the smoke zone and the indoor (fire room). Keep within.

그러나, 거주자의 피난시 제연구역으로부터 피난계단으로 연결된 출입 문의 일시적인 개방과 동시에 제연 구역내 압력은 급격히 강하 하는데 이때는 댐퍼 개구율을 100% 개방하여 제연구역에서 옥내(화재실) 방향으로 방연풍속을 0.7m/s이상 유지시켜 화재실 연기가 제연 구역으로 침투하지 못 하도록 하여야 하며, 또한 거주자의 탈출 후 출입문이 닫히는 순간, 풍도 최대 압력이 60Pa 이상으로 5초 이상 가해질 경우가 발생하는데, 이 경우 압력에 의해 출입문이 열리지 않을 수도 있어 노약자들의 피난에 오히려 장애가 될 수 있으므로, 출입문이 닫히기 직전, 제연구역의 차압을으로 신속히 복귀시키기 위해 댐퍼 개구부를 신속히 닫히도록 하여야 한다.However, at the time of the evacuation of the occupants, the pressure in the ventilation area drops drastically with the temporary opening of the entrance door connected from the ventilation area to the evacuation stairs. It should be kept over / s to prevent the fire room smoke from penetrating into the smoke control area.In addition, when the door is closed after the escape of the occupant, the maximum wind pressure may be applied for more than 5 seconds to 60 Pa or more. As the door may not be opened, it may impede the evacuation of the elderly, so just before the door closes, The damper opening should be closed quickly in order to return quickly.

즉, 단순히 제연구역 내에 설치된 댐퍼를 이용하여 제연구역내의 차압을 일정수준으로 유지하는 기능만으로는, 화재발생시에 발생하는 다양한 상황에 대해 능동적인 대처가 불가능하여 오히려 더 큰 인명피해를 입힐 수도 있다는 문제점이 있다.In other words, by simply maintaining the pressure differential in the ventilation area by using a damper installed in the ventilation area, it is impossible to proactively cope with various situations occurring in the event of a fire, which may cause more casualties. There is this.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 화재발생시에 제연설비의 출입문이 순간적으로 열림과 닫힘이 반복되는 특성에 능동적으로 대처하므로써 제연구역내의 차압을 일정수준으로 유지할 수 있도록 하기 위한, 적외선 차압 감지 장치를 제공하는데 그 목적이 있다.The present invention is to solve the above conventional problems, to actively maintain the differential pressure in the smoke control area by actively coping with the characteristic that the opening and closing of the door of the smoke control facility is instantaneously repeated in the event of a fire. To provide an infrared differential pressure detection device for that purpose.

본 발명에 따른 적외선 차압 감지 장치(200)는, 화재시 옥내의 제연 구역에 대한 차압을 조절하기 위한 것으로서, 특히 도 1a 에서는 계단형 아파트의 경우를 예로 하여 설명하고 있다.Infrared differential pressure detecting device 200 according to the present invention is for controlling the differential pressure of the smoke control area indoors in the event of a fire, in particular in FIG.

즉, 도면에 도시된 바와 같이, 본 발명에 따른 적외선 차압 감지 장치(200)는 일반적으로 댐퍼(100)와 함께 구성되어 있으며, 화재발생시 적외선 차압 감지 장치(200)가 제연구역과 화재발생구역(A 또는 B 구역)의 차압을 감지하여 댐퍼(100)의 개구부의 개폐를 조절하므로써 제연구역 내부로 인입되는 공기의 양을 조절하여 제연구역의 압력을 일정 수준으로 유지할 수 있도록 한다.That is, as shown in the drawings, the infrared differential pressure detecting device 200 according to the present invention is generally configured with a damper 100, the infrared differential pressure detecting device 200 in the event of a fire is the smoke generating zone and the fire generating zone ( A or B zone) by controlling the opening and closing of the opening of the damper 100 by sensing the differential pressure to control the amount of air introduced into the ventilation zone to maintain the pressure in the ventilation zone to a certain level.

이때, 댐퍼(100)는 화재발생시에 제연하고자 하는 제연구역을 제연구역 이외의 옥내(A 또는 B 구역)보다 일정한 기압()(차압) 만큼 높게 하여 옥내로부터 제연구역으로 연기가 침투하지 못하도록 하는 장치로서, 옥외의 공기를 제연구역으로 보충 공급하는 기능을 수행하며, 그 정면도와 측면도는 도 1b 및 도 1c 에 도시된 바와 같다.At this time, the damper 100 has a predetermined air pressure (in the A or B zone) other than the indoor ventilation zone other than the ventilation zone to be smoked when the fire occurs ( A device that prevents smoke from penetrating into the ventilation zone from indoors by increasing the differential pressure, and performs supplementary supply of outdoor air to the ventilation zone, the front and side views of which are illustrated in FIGS. 1B and 1C. same.

The configuration is shown in detail.

먼저, 도 2a 에 도시된 바와 같이 본 발명에 따른 적외선 감지 장치(200)는, 다이아 후레임(공기막)을 경계로 우측에 위치해 있으며 제연구역의 압력을 측정하기 위한 1차 제연구역 압력구(202), 다이야 후레임(공기막)을 경계로 좌측에 위치해 있으며 옥내의 압력을 측정하기 위한 2차 옥내 압력구(204), 상기 1차 제연구역 압력구와 2차 옥내 압력구로 부터 감지된 압력의 차압을 감지하기 위한 적외선 센서(60Pa, 40Pa, 10Pa)(206), 상기 1차 제연구역 압력구와 2차 옥내 압력구로부터 인가된 압력의 차이를 상기 적외선 센서로 전송하기 위한 차압조절봉 연결판(210), 1차 제연구역 압력구로 인가된 공기압력을 상기 차압조절봉 연결판으로 전달하기 위한 차압감지 연결 스프링(212), 차압조절봉 연결판에 의한 차압에 따라 민감하게 이동하며 상기 적외선 센서에 의해 감지되는 감지봉(214) 및 상기 적외선 센서에서 감지된 차압에 따라 댐퍼로부터 인입되는 공기양을 조절하기 위한 차압 조절봉(208)을 포함하여 구성되어 있다.First, as shown in FIG. 2A, the infrared sensing device 200 according to the present invention is located on the right side of the dia frame (air membrane) and measures the pressure of the primary smoke zone 202 for measuring the pressure of the smoke zone. , Located on the left side of the diamond frame (air membrane) on the left side, the secondary indoor pressure port 204 for measuring the pressure in the room, the pressure difference detected from the pressure in the primary smoke zone and the secondary indoor pressure port Infrared sensor (60Pa, 40Pa, 10Pa) 206, differential pressure control rod connecting plate 210 for transmitting the difference between the pressure applied from the primary smoke zone pressure port and the secondary indoor pressure port to the infrared sensor, 1 Differential pressure sensing connection spring 212 for transferring the air pressure applied to the pressure control port of the vehicle ventilation zone to the differential pressure control rod connecting plate, sensitively moved according to the differential pressure by the differential pressure control rod connecting plate and sensed by the infrared sensor The sensing rod 214 is supported, and the differential pressure adjusting rod 208 for adjusting the amount of air drawn from the damper according to the differential pressure sensed by the infrared sensor.

상기와 같은 구성을 갖는 본 발명에 따른 적외선 차압 감지부(200)의 작동 과정을 설명하면 다음과 같다.Referring to the operation of the infrared differential pressure detecting unit 200 according to the present invention having the configuration as described above are as follows.

즉, 화재 발생시 제연 설비가 작동되면 제연구역에 연결된 열려있는 모든 출입문이 닫히고, 적외선 차압 감지 장치는 제연 구역 차압을 40Pa~60Pa 이내로 유지하기 위해 댐퍼(100)를 통해 제연구역의 압력을 상승시킨다.That is, when the fire-fighting facility is operated at the time of fire, all open doors connected to the smoke-free area are closed, and the infrared differential pressure detecting device increases the pressure of the smoke-free area through the damper 100 to maintain the pressure difference between the smoke-free area within 40 Pa to 60Pa.

1차 제연구역 압력구(202)에 공기압이 상승하면 다이야 후레임(216)에 연결된 차압 감지 연결 스프링(212)에 압력을 전달하고, 압력이 더욱 상승하여, 차압 감지봉 연결판(210)의 2차 감지봉(218)이 40Pa 지점을 벗어나 60Pa 지점 사이(50Pa)를 유지할 경우 댐퍼 개구율은 그 상태를 계속적으로 유지하게 된다.When the air pressure rises in the primary ventilation zone pressure port 202, the pressure is transmitted to the differential pressure sensing connecting spring 212 connected to the diamond frame 216, and the pressure is further increased to increase the pressure of the differential pressure sensing rod connecting plate 210. When the difference detecting rod 218 is kept out of the 40Pa point and is maintained between the 60Pa points (50Pa), the damper opening ratio is continuously maintained.

또한, 60Pa 이상이 되면 댐퍼 개구율을 닫힘 상태로 진행하도록 하고, 40Pa 이하가 되면 댐퍼 개구율을 열림 상태로 되도록 조절하므로써, 댐퍼(100)의 열림과 닫힘 상태를 반복하면서 제연구역의 공기압을 일정 수준으로 유지하도록 한다.When the damper opening ratio is set to the closed state when 60 Pa or more, the damper opening ratio is adjusted to the open state when the damper opening ratio is 40 Pa or less, and the air pressure in the ventilation zone is kept at a predetermined level while repeating the opening and closing of the damper 100. Keep it.

또한, 피난시 출입문이 일시적으로 열릴 경우 제연구역의 압력이 0Pa이므로 댐퍼 개구율은 100%개방하여 제연구역에서 옥내 방향으로 출입문을 통과하는 공기속도를 0.7m/s 이상 유지하고, 출입문이 닫히기 직전 1차 감지봉(214)이 10Pa이내를 감지하여 댐퍼개구율을 닫힘 방향으로 약 5초간 진행하다가 출입문이 완전히 닫히면 2차 감지봉(218)이 60Pa 이상 감지되어 댐퍼 개구율은 계속 닫힘 방향으로 진행한다.In addition, if the door is temporarily opened during evacuation, the pressure in the ventilation area is 0Pa, so the damper opening ratio is 100% open, keeping the air velocity passing through the door in the indoor direction from the ventilation area more than 0.7m / s and immediately before the door is closed. When the vehicle detecting rod 214 detects less than 10 Pa and proceeds the damper opening ratio in the closing direction for about 5 seconds, when the door is completely closed, the secondary sensing rod 218 is detected by 60 Pa or more, and the damper opening ratio continues in the closing direction.

즉, 본 발명에 따른 적외선 차압 감지 장치(200)는 제연구역의 적정차압이 50Pa이 될때까지 댐퍼의 개구율을 조절하는 한편, 상기 적정차압이 되면 댐퍼 개구율을 잠시 정지하도록 하고, 40Pa 이하가 되면 다시 열림을 반복하도록 하므로써, 제연구역의 압력을 일정수준으로 유지할 수 있도록 하는 장치이다.That is, the infrared differential pressure detecting device 200 according to the present invention adjusts the opening ratio of the damper until the proper differential pressure of the ventilation zone is 50 Pa, while stopping the damper opening ratio for a while when the appropriate differential pressure reaches 40 Pa or lower, again. By repeating the opening, it is a device to maintain the pressure in the ventilation area at a constant level.

이때, 출입문의 닫힘순간에 제연구역의 차압이 최대 60Pa 이상을 5초 이내로제한 해야함으로 1차 감지봉(10Pa)(214)기능이 채용되었다.At this time, since the differential pressure of the smoke control area should be limited to a maximum of 60 Pa or more within 5 seconds at the moment of closing the door, a primary sensing rod (10Pa) 214 function was employed.

이상의 본 발명은 상기에서 기술된 실시예들에 의해 한정되지 않고, 당업자들에 의해 다양한 변형 및 변경을 가져올 수 있으며, 이는 첨부된 청구항에서 정의되는 본 발명의 취지와 범위에 포함된다.The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

상기와 같은 본 발명은 차압 감지 기능이 기계적이고, 접점편차 거리가 커 동작이 확실하며 시그널 접점 부위가 적외선 접점이므로 접점 순간의 제연구역 압력에 전혀 장애가 되지 않고 위치 검출이 정확하다는 우수한 효과가 있다.The present invention as described above has an excellent effect that the differential pressure detection function is mechanical, the contact distance is large, the operation is sure, and the signal contact portion is an infrared contact, so that the position detection is accurate without any obstacle to the pressure in the ventilation zone at the moment of contact.

또한, 본 발명은 화재 발생시 제연구역의 압력을 적절히 조절하므로써, 화재 발생구역에 있던 거주자가 제연구역을 통해 안전하게 피난할 수 있도록 할 수 있는 우수한 효과가 있다.In addition, the present invention has an excellent effect that can be properly evacuated through the smoke control area occupants in the fire generating area by appropriately adjusting the pressure of the smoke area when the fire occurs.
