Description

자동 차압 조절용 소방 급기댐퍼, 및 소방 급기댐퍼의 제어방법{Fire extinguisher damper for automatic pressure control, and control method thereof}FIELD OF THE INVENTION The present invention relates to a fire extinguisher damper for automatic pressure control,

본 발명은 자동 차압 조절용 소방 급기댐퍼, 및 소방 급기댐퍼의 제어방법에 관한 것으로, 더욱 상세하게는 건축물에 형성된 수직풍도와 각층의 전설 사이에 배치되어, 화재 발생시 수직풍도를 따라 유입되는 공기를 전실 내로 유입시켜 전실과 내실 사이에 설정차압을 형성함으로써, 내실과 전실과의 압력편차에 의해 전실을 따라 피난 계단실로 유입되는 현상을 방지하는 자동 차압 조절용 소방 급기댐퍼, 및 소방 급기댐퍼의 제어방법에 관한 것이다.More particularly, the present invention relates to a control method for a fire extinguisher damper for automatic pressure difference control, and more particularly, to a control method for a fire extinguisher damper And the control method of the fire extinguisher damper for controlling the automatic pressure difference and the fire extinguisher damper for preventing the phenomenon that the pressure difference between the inner chamber and the front chamber is introduced into the escape staircase along the entire room due to the pressure difference between the front chamber and the front chamber, .

국내에서는 건축물의 화재시 피난 계단실 내로의 연기침투를 방지하여 안전한 피난경로를 확보하기 위해, 화재안전기준 NFSC501A의 “특별피난계단의 계단실 및 전실 제연설비의 화재안전기준”이 제시되어 있다.In Korea, "fire safety standards for staircase and all room ventilation facilities of special escape stairway" of NFSC501A are proposed in order to secure the safe evacuation route by preventing smoke penetration into the evacuation staircase in case of fire in buildings.

상기 기준에서는, 제연구역으로 연기의 침투를 방지하기 위하여 제연구역과 내실 사이에 설정차압(50±20%)(스프링클러 설치시 12.5Pa 이상)을 유지하고, 방화문 개방에 필요한 개방력을 110N 이하가 되도록 하고 있다.In this standard, the set differential pressure (50 ± 20%) (12.5Pa or more when installing the sprinkler) is maintained between the ventilation area and the inner chamber to prevent the penetration of smoke into the ventilation area, and the opening force required for opening the fire door is 110N or less .

또한, 피난을 위해 제연구역의 방화문이 일시적으로 개방되는 경우, 0.5 m/s 내지 0.7 m/s 이상의 방연 풍속을 요구하도록 규정하고 있다.In addition, it is stipulated to require a smoke wind speed of 0.5 m / s to 0.7 m / s or more when the fire doors of the smoke-free area are temporarily opened for evacuation.

이에 당분야에서는, 화재 발생시 급기장치가 수직풍도를 따라 건축물의 각층의 내실과 계단실 사이에 위치하는 전실에 외부공기를 강제 급기하여, 내실과 피난 계단실 사이에 형성된 전실을 단독으로 가압하여 제연하는 급기 가압형 제연시스템을 구축하고 있다.Accordingly, in the related art, in the case of a fire, an air supply device forcibly supplies outside air to a front room located between the inner room and the stair room of each floor of a building along a vertical wind direction to pressurize the front room formed between the inner room and the evacuation staircase, Pressure type ventilation system.

상기 급기 가압형 제연시스템은, 건축물에 수직으로 형성된 수직풍도와, 상기 수직풍도에 외부공기를 강제 급기하는 급기장치와, 상기 수직풍도와 각 설치층의 전실 사이에 배치되어 설치층에 형성된 전실과 내실 사이의 차압값에 따라 수직풍도를 따라 수직으로 이동하는 외부공기의 유입여부와 유입량을 조절하여서, 전실에 설정차압을 형성하는 자동 차압 조절용 소방 급기댐퍼를 포함한다.The air supply pressurizing type smoke inducing system includes a vertical air flow formed vertically to a building, an air supply device for forcibly supplying outside air to the vertical air flow, a front air chamber disposed between the vertical air flow and the front air chamber, And a fire extinguisher damper for automatic pressure control for regulating the inflow amount and the inflow amount of the outside air moving vertically along the vertical wind direction according to the differential pressure value between the inner chambers and forming the set differential pressure in the all chambers.

상기 자동 차압 조절용 소방 급기댐퍼는, 전실과 수직풍도 사이에 배치되며, 급기구를 통해 수직풍도와 전실 사이를 연통시키는 댐퍼 하우징과; 상기 급기구의 개폐여부 및 개폐량을 포함하는 개폐상태를 설정하여 수직풍도를 따라 전실로 급기되는 외부공기의 유입여부와 유입량을 조절하는 급기량 조절부와; 상기 전실과 내실 사이의 차압을 계측하여 전실의 차압값을 계측하는 전실 차압 계측 센서와; 상기 전실 차압 계측센서를 통해 계측된 전실 차압값에 따라, 급기량 조절부의 구동을 제어하여 수직풍도에서 전실로 유입되는 외부공기 유입량을 조절하는 제어부를 포함한다.A damper housing disposed between the front chamber and the vertical air chamber and communicating between the vertical air chamber and the front chamber through the air supply mechanism; A supply amount adjusting unit for adjusting an inflow amount and an inflow amount of outside air supplied to the whole room along the vertical wind direction by setting an open / close state including the opening / closing amount of the air supply mechanism; A total chamber pressure measuring sensor for measuring a pressure difference between the front chamber and the inner chamber and measuring a pressure difference between the front chamber and the inner chamber; And a controller for controlling the driving of the air supply amount adjusting unit according to the total room pressure differential value measured through the all-room differential pressure measuring sensor to adjust the amount of the outside air inflow into the front room from the vertical air condition.

따라서, 상기 소방 급기댐퍼는 화재 발생시 차압 계측센서를 통해 내실과 전실 사이의 차압값을 계측하고, 상기 계측된 차압값에 따라 제어부는 급기댐퍼의 급기구에 마련된 급기량 조절부의 개폐날개를 조절하여서, 전실과 내실 사이에 설정차압이 지속적으로 유지되도록 한다.Accordingly, the fire-supply damper measures the differential pressure value between the inner chamber and the front chamber through the differential pressure measurement sensor when a fire occurs, and the control unit adjusts the opening / closing wings of the supply amount adjustment unit provided in the supply mechanism of the air supply damper according to the measured differential pressure value , So that the set pressure differential between the front and the front room is maintained constantly.

그런데, 실제 건축물에 시설된 급기 가압형 제연시스템의 현장 성능평가 결과, 각 전실에 설치된 소방 급기댐퍼가 설정차압이 형성된 것으로 인지하더라도, 실제 차압값이 설정차압값 보다 낮거나 높은 현상이 발생되어 소기의 운전성능을 발휘하지 못하는 것으로 확인되었다.However, as a result of the on-site performance evaluation of the air supply pressure type smoke ventilation system installed in an actual building, even if the fire supply damper installed in each room is recognized as a set differential pressure, the actual differential pressure value is lower or higher than the set differential pressure value, It is confirmed that it can not exert the driving performance of

즉, 소방 급기댐퍼의 차압 계측센서를 통해 계측된 전실의 계측 차압값이 설정차압을 형성한 것으로 인지하더라도, 전실의 실제 차압값이 설정차압을 형성하지 못하는 것으로 확인되었다.That is, even if the measured differential pressure value of all the rooms measured through the differential pressure measurement sensor of the firefighting and supply damper is recognized as forming the set differential pressure, it has been confirmed that the actual differential pressure value of the entire room does not form the set differential pressure.

이와 같이 전실의 실내온도에 따른 소방 급기댐퍼가 인식한 계측 차압값과 전실의 실제 차압값 사이의 편차가 발생되면, 소방 급기댐퍼는 화염의 확산을 방지하기 위해 전실의 설정차압을 형성하는 것이 사실상 어려워 소방 안전성 내지 신뢰성을 담보하기 어려운 한계성을 야기한다.When the deviation between the measured differential pressure value recognized by the firefighting damper according to the room temperature of the whole room and the actual differential pressure value of the entire room is generated, the firefighting and supply damper forms the set differential pressure of the entire room in order to prevent the spread of the flame It is difficult to secure fire safety or reliability.

상기 자동 차압 조절용 소방 급기댐퍼(1)는, 도 1 내지 도 3에서 보는 바와 같이 건축물의 각 설치층에 형성된 전실(120)과 건축물에 수직으로 형성된 수직풍도(110) 사이에 형성된 설치구(111)에 배치되며, 급기구(11)를 통해 수직풍도(110)와 설치층의 전실(120) 사이를 연통시키는 댐퍼 하우징(10)과; 상기 댐퍼 하우징(10)의 급기구(11)에 배치되어 급기구(11)의 개폐여부 및 개폐량을 포함하는 개폐상태를 설정하는 급기량 조절부(20)와; 상기 설치층의 전실(120)과 내실(130) 사이의 차압을 계측하여 전실(120)의 계측 차압값을 계측하는 차압 계측센서(30)와; 차압값에 따라 급기량 조절부(20)의 구동을 제어하는 제어부(50)를 포함한다.1 to 3, the automatic fire extinguisher fire fighting air supply damper 1 includes an installation room 111 formed between a front room 120 formed in each installed floor of a building and a vertical air space 110 formed perpendicularly to the building, , A damper housing (10) which communicates between the vertical wind direction (110) and the front room (120) of the installation floor through the air supply mechanism (11); A supply amount adjusting unit 20 disposed in the supply mechanism 11 of the damper housing 10 to set the open / close state including the opening / closing amount of the supply mechanism 11; A differential pressure measuring sensor (30) measuring a differential pressure between the front chamber (120) and the inner chamber (130) of the mounting layer and measuring the differential pressure value of the front chamber (120); And a control unit 50 for controlling the driving of the supply amount adjusting unit 20 according to the differential pressure value.

상기 제어부(50)는 수신반(51)을 통해 화재신호와, 차압 계측센서(30)를 통해 제공되는 계측 차압값, 그리고 후술되는 온도 계측센서(40)를 통해 제공되는 온도값을 실시간으로 제공받아서 급기량 조절부(20)를 제어한다.The control unit 50 receives the fire signal, the measured differential pressure value provided through the differential pressure measurement sensor 30, and the temperature value provided through the temperature measurement sensor 40, which are provided in real time, through the receiver unit 51 And controls the supply amount adjusting unit 20.

그리고, 상기 차압 계측센서(30)는 도 2 내지 도 4에서 보는 바와 같이 차압 계측을 요하는 내실(130)과 연통하는 제 1 오리피스관(31a)과 차압 계측을 요하는 전실(120)과 연통하는 제 2 오리피스관(31b)을 갖는 차압 계측실(31)과; 상기 차압 계측실(31)에 형성된 제 1 오리피스관(31a)과 제 2 오리피스관(31b) 사이에 배치되는 차압 계측유닛(32)을 포함한다.2 to 4, the differential pressure measurement sensor 30 includes a first orifice tube 31a communicating with the inner chamber 130 requiring differential pressure measurement and a second orifice tube 31a communicating with the front chamber 120 requiring differential pressure measurement A differential pressure measurement chamber 31 having a second orifice tube 31b; And a differential pressure measurement unit 32 disposed between the first orifice pipe 31a and the second orifice pipe 31b formed in the differential pressure measurement chamber 31. [

상기 차압 계측유닛(32)은, 제 1 오리피스관(32a)과 제 2 오리피스관(32b)을 차폐하며 제 1 오리피스관(32a)과 제 2 오리피스관(32b) 사이의 압력편차에 의해 탄성 변형되는 실리콘 재질의 탄성체(32a)와; 상기 탄성체(32a)에 적층되게 배치되어 압력편차에 의한 탄성체(32a)의 형상 변형에 의해 상하로 유동하는 가동부재(32b)와; 상기 가동부재(32b)의 저면에 적층되게 배치되어 가동부재(32b)의 유동에 의해 압전되어 압전전류를 생성하는 피에조 소자(32c); 및 상기 피에조 소자(32c)에게 출력되는 차압 계측전류를 수신반(51)으로 출력하는 출력유닛(32d)을 포함한다.The differential pressure measuring unit 32 shields the first orifice tube 32a and the second orifice tube 32b and is configured to generate a pressure difference between the first orifice tube 32a and the second orifice tube 32b, An elastic body 32a made of a silicone material; A movable member 32b which is stacked on the elastic member 32a and flows up and down due to the shape deformation of the elastic member 32a due to a pressure deviation; A piezoelectric element 32c which is stacked on the bottom surface of the movable member 32b and is piezoelectric due to the flow of the movable member 32b to generate a piezoelectric current; And an output unit 32d for outputting the differential pressure measurement current outputted to the piezo element 32c to the receiver unit 51. [

즉, 상기 차압 계측유닛(32)은 제 1 오리피스관(31a)과 제 2 오리피스관(31b)의 압력 편차에 의한 탄성체(32a)의 탄성 변형에 의해 가동부재(32b)에 의한 피에조 소자(32c)의 압전량이 증감되고, 피에조 소자(32c)는 증감된 압전량에 따라 압전전류를 가변시켜서 차압 계측전류를 제어부(50)의 수신반(51)에 인가한다.That is, the differential pressure measuring unit 32 is configured such that the elastic element 32a is deformed elastically by a pressure deviation between the first orifice tube 31a and the second orifice tube 31b, and the piezo element 32c And the piezoelectric element 32c varies the piezoelectric current in accordance with the increased or decreased amount of piezoelectricity and applies the differential pressure measurement current to the receiver 51 of the control unit 50. [

그리고, 상기 제어부(50)는 수신반(51)을 통해 차압 계측전류의 전류량, 또는 전압값을 측정하여, 차압 계측센서(30)를 통해 계측된 전실의 차압 계측값을 인식한다.The control unit 50 measures a current amount or a voltage value of the differential pressure measurement current through the receiver 51 and recognizes the differential pressure measurement value of the whole room measured through the differential pressure measurement sensor 30. [

따라서, 상기 제어부(50)는 수신반(51)을 통해 상황실이나 화재 감지센서 등으로부터 화재신호가 수신되면, 차압 계측센서(30)를 통해 전실(120)과 내실(130) 사이의 차압값을 실시간으로 계측하고, 상기 계측된 차압값에 따라 급기량 조절부(20)의 개폐량을 조절하여 전실(120)로 유입되는 외부공기의 유입량을 조절함으로써, 전실(120)의 실제 차압값이 설정차압을 형성하도록 한다.When the control unit 50 receives a fire signal from the control room or the fire detection sensor through the receiver 51, the control unit 50 determines the differential pressure value between the front chamber 120 and the inner chamber 130 through the differential pressure measurement sensor 30, The actual differential pressure value of the front chamber 120 is controlled by adjusting the opening and closing amount of the supply air amount adjusting unit 20 according to the measured differential pressure value to adjust the inflow amount of the outside air flowing into the front chamber 120, .

그런데, 상기 제 1 오리피스관(31a)과 제 2 오리피스관(31b) 사이에 배치되어 제 1 오리피스관(31a)과 제 2 오리피스관(31b) 사이의 압력편차에 의해 탄성 변형되는 탄성체(32a)는, 그 특성상 온도에 의해 동일한 차압값이 형성되더라도 탄성 변형량을 달리하고, 결과적으로 차압 계측센서(30)가 설치된 설치부위의 온도값에 따라 계측 차압값이 증감되는 계측 오류가 불가피하게 발생될 수 있다.An elastic body 32a disposed between the first orifice tube 31a and the second orifice tube 31b and elastically deformed by a pressure deviation between the first orifice tube 31a and the second orifice tube 31b, Even if the same differential pressure value is formed due to the characteristics thereof, the amount of elastic deformation is varied, and as a result, a measurement error in which the differential pressure value is increased or decreased in accordance with the temperature value of the installation site where the differential pressure measurement sensor 30 is installed is inevitably generated have.

이를 부연하고자, 본 발명자가 실제 절대 차압계측장비를 통해 소방 급기댐퍼를 통해 설정차압이 형성된 것으로 인식된 전실의 차압을 계측한 결과, 표 1과 같은 결과을 얻을 수 있었다.In order to achieve this, the present inventor measured the differential pressure of all the chambers recognized as having a set differential pressure through an actual absolute differential pressure measuring instrument through a firefighting damper, and as a result, the results as shown in Table 1 were obtained.

표 1을 살펴보면, 전실의 실내온도가 20℃에서는 소방 급기댐퍼가 인식한 계측 차압값과, 절대 차압계측장비를 통해 계측되는 전실의 실제 차압값이 비등한 것으로 확인되었으나, 2℃나 -15℃에서는 적게는 20%가량, 크게는 50%의 가량의 계측 편차가 발생되는 것으로 확인되었다.As shown in Table 1, when the room temperature of the whole room is 20 ° C, the measured differential pressure value recognized by the fire extinguisher damper is equal to the actual differential pressure value measured by the absolute differential pressure measuring device. However, at 2 ° C or -15 ° C It was confirmed that measurement deviations of about 20% and 50% were generated.

즉, 제 1 오리피스관(31a)과 제 2 오리피스관(31b) 사이의 압력편차를 감지하는 매체인 탄성체(32a)는 특성상 주위 기온이 낮아지면 유동성과 탄성이 저하되고, 결과적으로 탄성체(32a)가 위치한 주위 온도에 의해 계측 차압값이 가변되는 현상이 야기된다.That is, the elasticity of the elastic body 32a, which is a medium for sensing a pressure deviation between the first orifice tube 31a and the second orifice tube 31b, The measurement differential pressure value is varied depending on the ambient temperature at which the temperature sensor is located.

그런데, 상기 탄성체(32a)는 온도에 따라 항시 일정한 유동성과 탄성을 갖는 특성을 갖는다.However, the elastic body 32a has a constant fluidity and elasticity at all times depending on the temperature.

본 발명자는, 이러한 탄성체(32a)의 고유 특성에 따른 온도값 별 보정값을 산출 및 메모리(53a)에 저장하고, 상기 차압 계측센서(30)를 통해 계측된 계측 차압값에 계측된 온도값에 따른 보정값을 대입시켜 계측된 온도값에 따라 계측 차압값을 보정한 보정 차압값을 생성하고, 제어부(50)는 보정 차압값을 토대로 급기량 조절부(20)를 제어하여 전실(120)의 실제 차압값이 설정 차압값을 형성하도록 한다.The inventor of the present invention calculates a correction value for each temperature value according to the inherent characteristics of the elastic body 32a and stores the correction value for each temperature value in the memory 53a to calculate the measured differential pressure value measured through the differential pressure measurement sensor 30 And the control unit 50 controls the supply amount adjusting unit 20 based on the corrected differential pressure value to generate a corrected differential pressure value by correcting the measured differential pressure value of the entire chamber 120 So that the actual differential pressure value forms the set differential pressure value.

즉, 본 실시예에서는 상기 차압 계측센서(30)가 설치된 설치부위의 온도값을 계측하는 온도 계측센서(40)를 마련하고, 상기 제어부(50)에는 온도 계측센서(40)를 통해 수득된 온도값을 통해 보정값을 추출하고, 상기 추출된 보정값을 차압 계측센서(40)를 통해 계측된 계측 차압값에 대입시켜서 보정 차압값을 생성하도록 한다.That is, in the present embodiment, the temperature measuring sensor 40 for measuring the temperature value of the installation site provided with the differential pressure measurement sensor 30 is provided, and the control unit 50 is provided with the temperature And a corrected differential pressure value is generated by substituting the extracted correction value into the measured differential pressure value measured by the differential pressure measurement sensor 40. [

이를 상술하자면, 상기 제어부(50)에 온도 계측센서(40)를 계측된 온도값과 대응되는 보정값을 메모리에서 추출하는 보정값 추출유닛(53)과, 차압 계측센서(30)를 통해 실시간으로 계측되는 계측 차압값에 보정값 추출유닛(53)에서 추출된 보정값을 대입시켜 보정 차압값을 실시간 생성하는 보정 차압값 생성유닛(54), 및 상기 급기량 조절부(20)의 구동을 제어하여 외부공기 유입량을 자동 조절하는 구동 제어유닛(52)을 포함한다.A correction value extracting unit 53 for extracting a correction value corresponding to the temperature value measured by the temperature measuring sensor 40 from the memory, A correction differential pressure value generation unit 54 that substitutes the measured differential pressure value measured by the correction value extraction unit 53 for a measured differential pressure value to generate a corrected differential pressure value in real time, And a drive control unit (52) for automatically adjusting the external air inflow amount.

따라서, 상기 제어부(50)는 차압 계측센서(30)를 통해 계측된 계측 차압값에 온도 계측센서(40)를 통해 계측된 온도값에 따른 보정값을 대입시켜, 보정 차압값을 생성하고, 상기 보정 차압값을 기준으로 급기량 조절부의 개폐량을 조절하여서, 화재 발생시 전실 내에 실제 차압값이 설정차압을 형성함으로써, 안정된 제연상태가 형성되도록 한다.Therefore, the control unit 50 substitutes a correction value corresponding to the temperature value measured through the temperature measurement sensor 40 into the measured differential pressure value measured through the differential pressure measurement sensor 30 to generate a corrected differential pressure value, The amount of opening and closing of the supply amount adjusting section is adjusted based on the corrected differential pressure value so that a true differential pressure value is formed in the front chamber in the event of a fire so that a stable ventilation state is formed.

그리고, 상기 제어부(50)는 보정값 추출유닛(53)을 통해 온도 계측센서(40)를 통해 계측된 온도값과 대응되는 보정값을 메모리(53a)에서 추출한 다음, 보정 차압값 생성유닛(54)을 통해, 추출된 보정값을 계측 차압값에 대입시켜서 보정 차압값을 생성한다.The control unit 50 extracts a correction value corresponding to the temperature value measured through the temperature measurement sensor 40 through the correction value extraction unit 53 from the memory 53a and then outputs the correction value to the correction difference value generation unit 54 ), The corrected correction value is substituted into the measured differential pressure value to generate the corrected differential pressure value.

이러한 차압 계측센서(30)를 통해 수득된 계측 차압값의 보정을 통해 제어부(50)는, 전실(120)의 실제 차압값을 인식한 다음, 계측된 보정 차압값과 설정차압을 대조하여 급기량 조절부(20)의 개폐량을 조절한다.Through the correction of the measured differential pressure value obtained through the differential pressure measurement sensor 30, the control unit 50 recognizes the actual differential pressure value of the front chamber 120 and then compares the measured differential pressure difference with the set differential pressure, The opening and closing amount of the regulating portion 20 is adjusted.

이후, 상기 제어부(50)는 차압 계측센서(30)와 온도 계측센서(40)를 통해 수득되는 계측 차압값과 온도값을 통해 계측 차압값을 실시간으로 보정하고, 보정된 보정 차압값을 통해 급기량 조절부(20)를 통한 급기구의 개폐량을 제어하여서, 화재 발생시 전실(120) 내에 실제 차압값이 설정차압을 형성하여 안정된 제연상태를 확보한다.Thereafter, the control unit 50 corrects the measured differential pressure value in real time based on the measured differential pressure value and the temperature value obtained through the differential pressure measurement sensor 30 and the temperature measurement sensor 40, The amount of opening and closing of the air supply mechanism through the air-condition adjusting unit 20 is controlled so that the actual differential pressure value in the front chamber 120 in the event of a fire forms a set differential pressure to secure a stable ventilation state.
