본 발명은 이산화탄소(CO2) 가스를 측정하여 오염된 공기를 배출시켜 최적의 실내공기를 제공하기 위한 환기시스템에 관한 것으로서, 특히 홈오토메이션(HA)기기 등의 원격장치와의 통신을 통해 원격 통신 제어가 가능한 실내 공기질 관리를 위한 원격 통신 제어용 CO2 가스 측정장치 및 그 제어방법에 관한 것이다.The present invention relates to a ventilation system for providing optimal indoor air by measuring carbon dioxide (CO2) gas to discharge contaminated air, and in particular, remote communication control through communication with a remote device such as a home automation (HA) device. The present invention relates to a CO2 gas measuring device for telecommunication control for indoor air quality management, and a control method thereof.

현재 일반건물에 설치되어 있는 기존의 공조시스템은 대부분 온열환경, 즉 온도, 습도, 기류를 기초로 운영하고 있다. 이러한 공조시스템은 재실자에게 이산화탄소(CO2)를 비롯한 다른 오염인자를 그대로 노출시키고 있어, 실내에서 재실자가 불쾌감을 느낄 수 있기 때문에 인체 쾌적성 측면에서 많은 보완이 필요한 실정이다.The existing air conditioning systems installed in general buildings are mostly operated based on the thermal environment, that is, temperature, humidity, and airflow. Such an air conditioning system exposes inmates to other pollutants such as carbon dioxide (CO 2 ) as it is, and the inmates may feel unpleasant in the room, requiring much supplementation in terms of human comfort.

따라서, 재실자들로부터 발생되는 이산화탄소(CO2) 농도를 공중위생관리법과 건축법에서 제시한 기준농도인 1000ppm 이하로 유지시키면서 쾌적온열환경을 만족시켜주는 에너지 절약적 공조알고리즘이 필요하다.Therefore, there is a need for an energy-saving air conditioning algorithm that satisfies the comfortable thermal environment while maintaining the concentration of carbon dioxide (CO2) generated from occupants below 1000 ppm, the standard concentration suggested by the Public Health Control Act and the Building Act.

또한, 환경오염이 심각해지고 건강에 대한 관심이 높아짐에 따라 실내공기를 정화시키는 공기청정기가 개발되어 활발하게 판매되고 있다. 하지만, 이는 단순히 담배연기나 먼지 등을 흡입할 뿐 인체에 유해한 이산화탄소(CO2) 농도를 제어하지는 못한다.In addition, as environmental pollution becomes serious and interest in health increases, air cleaners for purifying indoor air have been developed and actively sold. However, it simply inhales cigarette smoke or dust and does not control the concentration of carbon dioxide (CO2), which is harmful to the human body.

그래서, 신규 입주 아파트 등의 주택들은 대개 각 방마다 이산화탄소(CO2) 가스를 측정하는 센서, 주방 등에는 이산화탄소(CO2)와 수소(H2) 등의 잡가스를 측정하는 센서 등을 설치하여 공기질을 관리할 수 있도록 되어 있다.

도 3의 (가) 및 (나)는 도 1에 보여진 CO2 가스 측정장치의 전면도 및 측면도이다.3A and 3B are front and side views of the CO 2 gas measuring apparatus shown in FIG. 1.

도 3의 (가)를 보면, 좌측 하단부에 센서부(20)가 앞을 향해 다소 돌출된 형태로 배치되며, 그 옆에 키입력부(50)의 업(△)/다운(▽) 누름스위치(55)가 배치된다. 상단부에는 표시부(40)의 LCD(41)가 배치된다.Referring to (a) of Figure 3, the sensor unit 20 is arranged in the form of a slightly protruding forward to the lower left portion, next to the up (△) / down (▽) push switch of the key input unit 50 ( 55) is arranged. The LCD 41 of the display unit 40 is disposed at the upper end.

도 3의 (나)를 보면, 장치 뒷면에 돌출부가 마련되어 벽면 안쪽에 고정 장착되어 안정적으로 벽면 설치가 용이한 형태로 제작된다. Referring to Figure 3 (b), the projection is provided on the back of the device is fixedly mounted on the inside of the wall is produced in a stable form easy to install the wall.

이러한 형태로 제작 및 구성되는 도 1 내지 도 3 장치의 CO2 가스 측정 및 제어 동작을 도 4를 통해 구체적으로 설명한다.The CO2 gas measurement and control operation of the apparatus of FIGS. 1 to 3 manufactured and configured in this manner will be described in detail with reference to FIG. 4.

전원부(10)는 AC 220V의 입력전원을 DC 5V로 변환하여 각 구성의 동작전원으로 공급한다(단계 401). 전원이 인가되면, 대기모드로 동작하여 오동작 방지를 위한 초기화 작업을 수행한다(단계 402). 즉, 전원 투입 후 2분 30초간 센서부(20)를 초기화시키며, 이때 표시부(40)의 LCD(41)에는 0000ppm을 표기하고, 다수의 LED(45)를 모두 점멸 상태로 만든다. 초기화 작업이 완료되면, 운전모드로 동작한다(단계 403). 운전모드에서, 센서부(20)는 10초 마다 CO2 농도를 측정한다(단계 404). 센서부(20)의 검지범위는 통상 400∼5400ppm으로, 청정대기중을 400ppm으로 한다. 측정된 CO2 농도는 제어부(30)로 입력된다. 제어부(30)는 센서부(20)에서 측정된 CO2 농도를 표시부(40)의 LCD(41)에 표시하여 사용자로 하여금 현재의 CO2 농도를 알 수 있도록 한다. 제어부(30)는 또한, 현재의 운전상태 및 CO2 농도를 RS-485 통신부(70)를 통해 원격장치(80)로 전송한다. 제어부(30)는 측정된 CO2 농도를 설정치와 비교한다. 여기서, 설정치는 경보설정농도로, 키입력부(50)의 딥스위치(51)를 통해 초기 디폴트값으로 1000ppm이 설정된다. 사용자는 키입력부(50)의 누름스위치(55)를 조작하여 초기 디폴트값 1000ppm을 ±10ppm씩 변경 설정한다. 제어부(30)는 현재 CO2 농도가 1600ppm 이상인 지를 판단하여(단계 405), 이상이면 표시부(40)의 다수 LED(45)중 적색(R) LED를 점등시키고, 출력부(60)를 통해 경보출력1을 출력한다(단계 406). 즉, 출력부(60)는 복수개의 릴레이를 동작시켜 복수개의 공조 팬을 모두 가동시켜 실내의 CO2 가스를 환기시킨다. The power supply unit 10 converts the input power of AC 220V into DC 5V and supplies it to the operating power of each component (step 401). When the power is applied, it operates in the standby mode and performs an initialization operation for preventing malfunction (step 402). That is, the sensor unit 20 is initialized for 2 minutes and 30 seconds after the power is turned on. At this time, the LCD 41 of the display unit 40 displays 0000 ppm, and makes all the LEDs 45 blink. When the initialization operation is completed, the operation mode is operated (step 403). In the operation mode, the sensor unit 20 measures the CO 2 concentration every 10 seconds (step 404). The detection range of the sensor unit 20 is usually 400 to 5400 ppm, and the clean air is 400 ppm. The measured CO 2 concentration is input to the controller 30. The controller 30 displays the CO 2 concentration measured by the sensor unit 20 on the LCD 41 of the display unit 40 so that the user can know the current CO 2 concentration. The control unit 30 also transmits the current operating state and the CO 2 concentration to the remote device 80 through the RS-485 communication unit 70. The controller 30 compares the measured CO 2 concentration with a set value. Here, the set value is set to the alarm setting concentration, 1000ppm is set to the initial default value through the dip switch 51 of the key input unit 50. The user operates the push switch 55 of the key input unit 50 to change and set the initial default value 1000 ppm by ± 10 ppm. The controller 30 determines whether the current CO2 concentration is 1600 ppm or more (step 405), and if it is abnormal, turns on the red (R) LED of the plurality of LEDs 45 of the display unit 40, and outputs an alarm through the output unit 60. Output 1 (step 406). That is, the output unit 60 operates the plurality of relays to operate all of the plurality of air conditioning fans to ventilate the indoor CO 2 gas.

제어부(30)는 또한, 현재 CO2 농도가 사용자 설정치 즉, 1000ppm ±α이상인 지를 판단하여(단계 407), 이상이면 표시부(40)의 다수 LED(45) 중 노란색(Y) LED를 점등시키고, 출력부(60)를 통해 경보출력2를 출력한다(단계 408). 즉, 출력부(60)는 복수개의 릴레이중 하나의 릴레이만을 동작시켜 복수개의 공조 팬중 1개의 팬만이 가동되도록 한다. 제어부(30)는 현재 CO2 농도가 설정치 이하이면 표시부(40)의 다수 LED(45) 중 녹색(G) LED를 점등시킨다. 이때, 출력부(60)는 동작하지 않다.The control unit 30 also determines whether the current CO2 concentration is equal to or greater than the user setting value, that is, 1000 ppm ± α (step 407), and if it is abnormal, turns on the yellow (Y) LED of the plurality of LEDs 45 of the display unit 40 and outputs the result. The alarm output 2 is output through the unit 60 (step 408). That is, the output unit 60 operates only one relay of the plurality of relays so that only one fan of the plurality of air conditioning fans is operated. The controller 30 turns on the green (G) LED of the plurality of LEDs 45 of the display unit 40 when the current CO 2 concentration is lower than or equal to the set value. At this time, the output unit 60 does not operate.

한편, 원격장치(80)는 CO2 측정 장치와의 RS-485 통신을 통해 현재의 운전모드, CO2 농도, 경보출력상태를 전송받으며, 필요에 따라 경보설정농도의 변경을 원격 통신 제어한다. On the other hand, the remote device 80 receives the current operation mode, the CO2 concentration, the alarm output state through RS-485 communication with the CO2 measuring device, and remotely control the change of the alarm setting concentration as needed.

본 실시예에서는 CO2에 한정하여 설명하였지만, 측정 대상에 H2 등의 잡가스도 포함시켜 확대 적용할 수 있음은 구체적으로 설명하지 않더라도 당업자에게는 자명하다.Although the present embodiment has been described as being limited to CO2, it will be apparent to those skilled in the art even if the present invention is not specifically described, but can be expanded by including miscellaneous gases such as H2 in the measurement target.

상술한 바와 같이, 본 발명의 실내 공기질 관리를 위한 원격 통신 제어용 이산화탄소(CO2) 가스 측정장치 및 그 제어방법은, 일정주기로 CO2 가스 농도를 측정하여 현재 CO2 농도가 경보설정농도 이상이면 경보출력하여 환기되도록 하므로써 항시 사용자 설정의 실내 CO2 농도가 자동으로 유지되도록 하며, 원격 통신 제어에 의해 경보설정농도를 변경 설정하므로써 최적의 공기질 관리를 할 수 있는 효과를 갖는다.As described above, the remote communication control carbon dioxide (CO2) gas measuring apparatus and the control method for indoor air quality management of the present invention, by measuring the CO2 gas concentration at regular intervals, when the current CO2 concentration is above the alarm set concentration, the alarm output and ventilate The indoor CO2 concentration of the user setting is automatically maintained at all times, and the optimum air quality management can be performed by changing and setting the alarm setting concentration by remote communication control.
