복합댐퍼{Composition Damper}Composition Damper

본 발명은 화재시 건축물의 제연구역으로 외기를 송풍하여 제연구역의 공기압을 비제연구역의 기압보다 높게 하여 화재가 발생된 실내의 연기 및 유독가스가 제연구역으로 빠져나오지 못하도록 하는 제연설비에 있어서, 건물의 각층 제연구역으로 외기를 송풍하는 송풍기의 풍량을 제어하는 복합댐퍼에 관한 것이다.The present invention provides a smoke control system that blows outside air to the smoke control area of the building in the event of a fire so that the air pressure of the smoke control area is higher than the air pressure of the non-smoke control area to prevent the smoke and toxic gas in the room where the fire is generated from escaping into the smoke control area. The present invention relates to a composite damper that controls the air volume of a blower that blows outside air to the ventilation area of each floor of a building.

일반적으로 고층 건물에 있어서 비상 엘리베이터 앞이나 피난계단 앞의 전실 등은 제연구역으로 명칭되며, 상기 제연구역은 화재시 유해가스가 유입되지 못하도록 하는 제연설비를 갖추게 된다.In general, in a high-rise building, the front of the emergency elevator or the front of the evacuation stairs is called a ventilation area, and the ventilation area is equipped with a ventilation facility that prevents harmful gas from entering in the event of fire.

상기 고층건물의 제연구역에 설치되는 제연설비의 대표적인 것은 급기덕트와 급기댐퍼로, 화재시 급기덕트 앞의 급기댐퍼를 개방하여 외기를 제연구역으로 유입하게 된다. 즉, 고층건물의 각층 제연구역에 설치되는 급기댐퍼는 평소에는 닫혀있지만 화재신호에 의해 개방되어, 건물의 수직풍도와 연결되는 급기덕트로 공급되는 외기를, 제연구역으로 유입하여, 제연구역의 공기압을 높게 유지하게 된다.Representative of the ventilation equipment installed in the ventilation area of the high-rise building is an air supply duct and an air supply damper, and in the event of a fire, the air supply damper in front of the air supply duct is opened to introduce the outside air into the air conditioning area. In other words, the air supply damper installed in the smoke control area on each floor of a high-rise building is normally closed but is opened by a fire signal, and the air supplied to the air supply duct connected to the air supply duct connected to the building's vertical wind flows into the smoke control area. Will be kept high.

이와 같이 전실 즉 제연구역으로 유입되는 외기는 전실의 공기압을 높여 화재가 발생된 실내의 연기가 전실로 빠져나오지 못하게 함으로써 제연구역을 형성하게 된다.As such, the outside air flowing into the front room, that is, the smoke control area, increases the air pressure in the room, thereby preventing smoke from the fire-producing room from escaping into the room.

이와 같이 화재 발생시 제연구역의 공기압을 높여줌으로, 화재가 발생된 실내의 연기나 유독가스가 제연구역으로 유입되는 것을 차단하게 되며, 화재가 발생된 실내의 사람은 연기가 없는 제연구역을 거쳐 피난계단 또는 비상엘레베이터실로 대피하여, 귀중한 인명을 보호하게 되는 것이다.In this way, by increasing the air pressure of the smoke-producing area in the event of a fire, the smoke or toxic gas in the room where the fire is generated is blocked from entering the smoke-producing area. Or evacuate to the emergency elevator room to protect valuable lives.

상기 제연구역의 공기압은 비제연구역의 공기압보다 50Pa±20%파스칼(Pascal) 이내의 공기차압을 화재시 유지해야 한다고 소방법규에서 정하고 있다.The air pressure in the smoke control area is required by the Code of Regulations to maintain the air pressure difference within 50 Pa ± 20% Pascal in case of fire.

한편 제연구역으로 외기를 송풍하는 송풍장치는 건물의 옥상이나 건물의 지하층에 설치하는 송풍기와, 상기 송풍기에서 발생된 바람의 양을 제어하는 바람제어장치와, 외기를 이송하는 수직풍도로 구성되는바, 본 발명은 상기 송풍장치 중 송풍기 앞에 설치하여 바람의 양을 제어하는 복합댐퍼에 관한 것이다.On the other hand, a blower for blowing outside air to the ventilation area is composed of a blower installed on the roof of the building or the basement floor of the building, a wind control device for controlling the amount of wind generated by the blower, and a vertical wind conveying the outside air. The present invention relates to a composite damper installed in front of the blower of the blower to control the amount of wind.

건물 각층의 제연구역과 수직풍도 사이에는 급기댐퍼를 설치하여 제연구역으로 외기를 유입하게 된다. 상기 급기댐퍼는 평시에는 닫혀있으나, 화재시 화재신호에 의해 자동으로 개방되어 수직풍도를 통해 공급되는 외기를 제연구역으로 유입하게 된다.An air supply damper is installed between the smoke control area and the vertical wind of each floor of the building to introduce fresh air into the smoke control area. The air supply damper is normally closed, but in case of a fire, the air damper is automatically opened by a fire signal, thereby introducing fresh air supplied through the vertical wind into the ventilation area.

상기 급기댐퍼의 개폐날개(브레이드)는 개폐각을 조절하여 수직풍도로부터 유입되는 외기의 양을 조절하여, 제연구역의 공기압을 비제연구역보다 40~60Pa(50Pa±20%) 이내를 유지하여 화재가 발생된 실내의 연기나 유독가스가 문틈을 타고 빠져나오는 것을 방지하게 된다.The opening and closing blades (blades) of the air supply damper controls the amount of outside air introduced from the vertical wind by adjusting the opening and closing angles to maintain the air pressure in the ventilation area within 40 to 60 Pa (50 Pa ± 20%) than the non-smoke control area. It will prevent the smoke or toxic gas generated in the room to escape through the door.

또한, 화재시 실내의 사람이 출입문을 열고 피난할 경우, 열린 출입문을 통해 화재가 발생된 실내의 연기가 제연구역으로 빠져나오는 것을 방지하게 되며, 제 연구역의 공기차압이 40Pa 이하로 될 경우 즉, 출입문이 개방되어 제연구역의 공기가 실내로 유입됨으로 제연구역의 공기압이 낮아질 경우, 급기댐퍼는 100% 개방되어, 제연구역에서 개방된 출입문을 통해 실내로 유입되는 방연풍속은 0.7m/s 이상으로 공기속도를 유지하여, 개방된 출입문으로 실내의 연기가 제연구역으로 빠져나오지 못하도록 급기댐퍼는 100% 개방되는 작동을 수행하게 된다.In addition, if a person in the room evacuates by opening the door during the fire, it prevents the smoke inside the fire generated room through the open door to escape to the smoke control area, if the air pressure difference in my research area is less than 40Pa If the air pressure in the ventilation area is lowered because the door is opened and the air in the ventilation area is introduced into the room, the air supply damper is 100% open, and the smoke-free wind velocity flowing into the room through the door opened in the ventilation area is 0.7m / s or more. By maintaining the air speed, the air supply damper is 100% open to prevent the smoke from the room to the ventilation area through the open door.

또한, 상기 출입문이 닫혀질 경우, 즉 화재가 발생된 실내로부터 제연구역으로 사람이 대피한 후 출입문이 닫혀질 경우, 개방된 급기댐퍼로부터 제연구역으로 유입되던 외기(0.7m/s 이상의 속도로 유입되던 외기)에 의해 제연구역의 공기차압이 60Pa 이상으로 작용할 경우, 급기댐퍼는 급기량을 조절하여 닫히기 시작하여, 제연구역의 공기차압이 40~60Pa(50Pa±20%이내)로 유지하는 작용을 하게 된다.In addition, when the door is closed, that is, when the door is closed after evacuating a person from the room where the fire is generated to the ventilation area, the outside air flowed into the ventilation area from the open air supply damper (at a speed of 0.7 m / s or more) When the air differential pressure in the ventilation zone is 60 Pa or more due to the outside air, the air supply damper starts to close by adjusting the air supply amount, and the air differential pressure in the ventilation zone is maintained at 40 to 60 Pa (within 50 Pa ± 20%). Done.

또한 제연구역으로 피난한 사람이 피난계단으로 통하는 피난문(방화문)을 열 경우, 제연구역의 공기가 열린 피난문(방화문)을 통해 빠져나감으로 제연구역의 공기압이 낮아질 경우, 재차 급기댐퍼는 개방되어 제연구역으로 공기를 유입시켜, 제연구역의 공기차압을 40~60Pa이내로 상승 조절하는 작용을 반복적으로 수행하게 된다.In addition, when the evacuation door (fire door) opens to the evacuation stairs, the evacuation door (fire door) exits through the open evacuation door (fire door). As a result, the air is introduced into the ventilation zone, and the air differential pressure of the ventilation zone is repeatedly adjusted to be within 40 to 60 Pa.

(다만, 제연구역 내의 옥내 출입문이 20층 이내는 1개층, 20층 이상은 2개 층을 동시 개방할 시 방연풍속이 0.7m/s 이상을 유지하며, 동시에 비개방층의 제연구역 공기차압은 70%(28Pa)이상을 유지해야 한다고 규정함.)(However, when the indoor doors in the smoke control area open less than 20 floors at the same time and open more than two floors at the same time, the smoke-free wind velocity is maintained at 0.7 m / s or more. It is required to maintain more than 70% (28Pa).)

상기와 같은 제연구역의 설계기준을 요약하면 다음과 같다.The design criteria of the above-mentioned ventilation zone are summarized as follows.

1. 제연구역은 옥내 출입문과 피난계단으로 통하는 방화문(피난계단 출입문) 이 모두 닫힘 상태일 경우에는 제연구역의 공기차압은 40~60Pa이내를 유지할 것.1. The ventilation area should maintain the air differential pressure within the range of 40 ~ 60Pa when both the indoor door and the fire door (evacuation step door) leading to the evacuation stairs are closed.

2. 화재가 발생된 실내의 사람이 옥내 출입문을 개방할 시 급기댐퍼는 순간 100% 개방되어 제연구역으로 유입되는 공기는 옥내 방향으로 0.7m/s 이상의 방연 풍속을 유지할 것.2. When a fire breaks open the indoor door, the air supply damper is 100% open at the moment, and the air flowing into the smoke control area should keep the wind speed of more than 0.7m / s in the indoor direction.

3. 20층 이하의 건축물은 옥내 출입문이 1개층을 개방하거나, 20층 이상의 건축물은 옥내 출입문이 2개층이 동시에 개방될 시 방연풍속이 0.7m/s 이상을 유지하며, 동시에 비개방층의 제연구역 내의 공기차압은 70%(28Pa) 이상을 유지하도록 할 것.3. For buildings below 20 floors, indoor doors open one floor, while buildings over 20 floors open two floors at the same time, and the wind speed is 0.7 m / s or more. Ensure that the differential air pressure in the area is at least 70% (28Pa).

이라는 3가지 충족 요건으로 제연구역은 설계되어야 한다.The ventilation zones must be designed with three fulfillment requirements.

상기와 같은 제연구역의 3가지 충족요건을 구비해야 하나, 건물의 층수 및 형태 또는 설계에 따라, 상기 1번의 요건은 만족하나, 2번은 일부 만족을 볼 수 있으며, 또한 최근 고층화되는 건축물을 감안할 때 상기 3번의 요건을 동시에 만족하는 제연설비를 구현하는 데에는 많은 어려움을 갖게 된다.The three requirements of the smoke control area as above should be provided, but according to the number of floors and the shape or design of the building, the requirements of No. 1 are satisfied, but the No. 2 is partially satisfactory, and also considering the recent high-rise building. There is a lot of difficulty in implementing a ventilation system that satisfies the three requirements at the same time.

이를 감안하여 본 발명이 안출된 것으로 본 발명은 상기 제연구역이 갖는 설계 기준 요건을 모두 만족하는 제연구역을 제공하는 것이다.In view of this, the present invention has been made, and the present invention is to provide a ventilation area that satisfies all the design criteria requirements of the ventilation area.
