본 발명은 동일공간에 복수의 환기장치를 설치하여 넓은 공간을 환기시키는 환기시스템에 관한 것으로, 특히 복수의 환기장치가 고르게 운전되도록 하는 환기시스템의 운전제어방법에 관한 것이다.The present invention relates to a ventilation system for ventilating a wide space by installing a plurality of ventilation devices in the same space, and more particularly, to a method of controlling a ventilation system for allowing a plurality of ventilation devices to operate evenly.

일반적으로, 집이나 사무실 등의 밀폐된 공간에서는 사람의 호흡에 의해 시간이 지나면서 이산화탄소(CO2)의 함량이 증가하게 되어 공기가 탁해지고, 이로 인 해 사람의 호흡에 지장을 주게 된다. 따라서 실내의 오염된 공기를 실외로 배출시키고 실외의 쾌적한 공기를 실내로 유입시켜 실내공기를 환기시키는 환기장치가 개발되었으며, 여름이나 겨울철에 실내외 공기의 온도차가 클 경우 환기과정에서 발생하는 열손실을 줄이기 위해 전열교환소자를 채용하고 있다.In general, in a confined space such as a home or office, the content of carbon dioxide (CO 2 ) increases over time by human breathing, and the air becomes cloudy, which causes a problem of human breathing. Therefore, a ventilator was developed to discharge indoor polluted air to the outside and to introduce indoor air into the room to ventilate the indoor air.In the summer or winter, when the temperature difference between indoor and outdoor air is large, heat loss generated during the ventilation process In order to reduce the total heat exchange element is adopted.

이러한 전열교환소자를 채용한 환기장치로는 대한민국 공개특허공보 2003-0063856호가 있다.Ventilation apparatus employing such a total heat exchange element is disclosed in Republic of Korea Patent Publication No. 2003-0063856.

동 공보에 개시된 환기장치는 실외공기의 급기유로와 실내공기의 배기유로가 교차하는 지점에 설치되어 실외공기와 실내공기 사이에 열교환이 이루어지도록 하는 전열교환소자와, 급기유로상에 설치된 급기팬과, 배기유로상에 설치된 배기팬을 구비하여, 급기팬과 배기팬이 회전하면 급기유로를 통해 실외공기가 실내로 유입되고, 배기유로를 통해 실내공기가 실외로 배출되며, 배출되는 실내공기와 유입되는 실외공기 사이에 열교환이 일어난다.The ventilator disclosed in this publication is installed at the point where the air supply passage of outdoor air and the exhaust passage of indoor air intersect, and the heat exchange element which exchanges heat between outdoor air and indoor air, an air supply fan installed on the air supply passage, And an exhaust fan installed on the exhaust passage, and when the air supply fan and the exhaust fan rotate, outdoor air is introduced into the room through the air supply passage, and indoor air is discharged to the outside through the exhaust passage. Heat exchange occurs between the outdoor air.

최근에는 이러한 환기장치에 청정기능을 위해 공기에 포함된 먼지나 각종 이물질 등을 제거하기 위한 필터를 설치하여 일정시간마다 교체 또는 청소를 해주고 있다.Recently, a filter for removing dust or various foreign substances contained in the air for cleaning function is installed in such a ventilation device and replaced or cleaned at regular intervals.

In this case, when the ventilation demand (indoor pollution) is large, a plurality of ventilation devices are operated and each ventilation device has the same cumulative operation time. In this case, only a part of the ventilation device is operated, and the cumulative operation time of each ventilation device is changed, so that the life of the ventilation device or the filter replacement time is also inconvenient.

또한, 상기 복수의 환기장치(10-1 ~ 10-n)에는 각 환기장치(10-1 ~ 10-n)의 운전동작을 개별적으로 제어하는 제어기(10a-1 ~ 10a-n)가 마련되며, 각 환기장치(10-1 ~ 10-n)의 제어기(10a-1 ~ 10a-n)는 상기 오염도검출부(30)로부터 검출된 센서값에 따라 실내 오염도를 측정하고, 측정된 실내 오염도에 따라 환기장치(10-1 ~ 10-n)의 운전대수(용량)를 결정한다.In addition, the plurality of ventilation devices 10-1 to 10-n are provided with controllers 10a-1 to 10a-n for individually controlling the operation of each of the ventilation devices 10-1 to 10-n. The controllers 10a-1 to 10a-n of the ventilation apparatuses 10-1 to 10-n measure indoor pollution levels according to sensor values detected from the pollution degree detecting unit 30, and according to the measured indoor pollution levels.

또한, 각 제어기(10a-1 ~ 10a-n)는 각 환기장치(10-1 ~ 10-n)의 누적운전시간, 필터 사용시간, 필터 오염도 등의 데이터를 저장 관리하며, 다른 환기장치(10-1 ~ 10-n)의 제어기(10a-1 ~ 10a-n)와 유무선 통신을 통해 누적운전시간 등의 데이터를 교환하여 각 환기장치(10-1 ~ 10-n)의 누적운전시간에 따라 복수의 환기장치(10-1 ~ 10-n)가 고르게 운전되도록 운전순서를 결정하게 된다.In addition, each controller 10a-1 to 10a-n stores and manages data such as cumulative operation time, filter use time, and filter contamination level of each ventilation device 10-1 to 10-n, and other ventilation devices 10 By exchanging data such as cumulative operation time through wired / wireless communication with the controllers 10a-1 to 10a-n of -1 to 10-n), according to the cumulative operation time of each ventilator 10-1 to 10-n The operation sequence is determined so that the plurality of ventilation devices 10-1 to 10-n operate evenly.

이하, 상기와 같이 구성된 환기시스템의 운전제어방법의 동작과정 및 작용효과를 설명한다.Hereinafter, the operation process and the effect of the operation control method of the ventilation system configured as described above will be described.

본 발명의 환기시스템에서, 각 환기장치(10-1 ~ 10-n)는 유무선 통신을 이용하여 누적운전시간 등의 데이터를 서로 송수신하며, 각 환기장치(10-1 ~ 10-n)간에 데이터를 서로 송수신하지 않고 중앙제어기(20)로 환기장치(10-1 ~ 10-n)의 데이터를 송신할 수 있게 되어 알고리즘 구성에 따라 각 환기장치(10-1 ~ 10-n)의 제어기 (10a-1 ~ 10a-n) 또는 중앙제어기(20)에서 환기장치(10-1 ~ 10-n)의 운전대수와 운전순서를 결정할 수 있다.In the ventilation system of the present invention, each ventilator (10-1 ~ 10-n) transmits and receives each other data such as cumulative operation time using wired and wireless communication, data between each ventilator (10-1 ~ 10-n) It is possible to transmit the data of the ventilator (10-1 ~ 10-n) to the central controller 20 without transmitting and receiving each other, so that the controller (10a) of each ventilator (10-1 ~ 10-n) according to the algorithm configuration -1 to 10a-n) or the central controller 20 can determine the number of driving units and the operation order of the ventilator (10-1 ~ 10-n).

도 3은 본 발명에 의한 환기시스템의 운전제어방법의 동작 흐름도로서, 중앙제어기(20)에서 각 환기장치(10-1 ~ 10-n)의 데이터를 모두 통합하여 환기장치(10-1 ~ 10-n)의 운전대수와 운전순서를 결정하는 것을 예로 들어 설명한다.3 is an operation flowchart of the operation control method of the ventilation system according to the present invention, in which the central controller 20 integrates all the data of each of the ventilation apparatuses 10-1 to 10-n to the ventilation apparatus 10-1 to 10. -n) will be described with an example of determining the number of operation and the order of operation.

먼저, 시스템 운전자가 리모콘이나 중앙제어기(20)를 이용하여 전체 또는 개별적으로 환기시스템의 운전신호를 입력하면(S100), 중앙제어기(20)는 각 환기장치(10-1 ~ 10-n)의 제어기(10a-1 ~ 10a-n)로부터 누적운전시간 데이터를 입력받아 각 환기장치(10-1 ~ 10-n)의 누적운전시간을 체크한다.First, when the system driver inputs a driving signal of the ventilation system in whole or individually using the remote controller or the central controller 20 (S100), the central controller 20 is configured to control each of the ventilation apparatuses 10-1 to 10-n. The cumulative operation time of each ventilator 10-1 to 10-n is checked by receiving the accumulated operation time data from the controllers 10a-1 to 10a-n.

이후, 복수의 환기장치(10-1 ~ 10-n) 가운데 적어도 하나 이상에 설치된 오염도검출부(30)에서 환기시스템이 설치된 실내공기의 유해물질 및 CO2농도를 검출하여 중앙제어기(20)에 입력한다(S110).Thereafter, the pollution degree detection unit 30 installed in at least one of the plurality of ventilation devices 10-1 to 10-n detects harmful substances and CO 2 concentration of indoor air in which the ventilation system is installed and inputs them to the central controller 20. (S110).

따라서, 중앙제어기(20)는 오염도검출부(30)로부터 검출된 센서값을 입력받아 실내 오염도를 측정하고, 측정된 실내 오염도가 미리 정해진 기준값(환기운전이 필요한 시점의 CO2농도, 약 500ppm) 이상인가를 판단한다(S120).Therefore, the central controller 20 receives the sensor value detected from the pollution degree detecting unit 30 and measures the indoor pollution level, and the measured indoor pollution degree is equal to or greater than a predetermined reference value (CO 2 concentration at the time of ventilation operation, about 500 ppm). The authorization is determined (S120).

상기 실내 오염도가 환기운전이 필요한 기준값 이상이면, 중앙제어기(20)는 실내 오염도에 따라 환기장치(10-1 ~ 10-n)의 운전대수(용량)를 도 2에 도시한 바와 같이, 결정한다(S130).If the indoor pollution degree is greater than or equal to the reference value that requires the ventilation operation, the central controller 20 determines the number of driving units (capacity) of the ventilation devices 10-1 to 10-n according to the indoor pollution degree, as shown in FIG. 2. (S130).

도 2에서, 실내 오염도가 500ppm 미만의 E영역에서는 환기운전이 필요하지 않은 시점이므로 제1~제5환기장치(10-1 ~ 10-5)의 전체 세트를 오프시키고, 500~800ppm 사이의 D영역에서는 환기시스템의 전체 용량을 100이라고 했을 때 20% 운전, 800~1000ppm 사이의 C영역에서는 50% 운전, 1000~1200ppm 사이의 B영역에서는 80% 운전, 1200ppm 이상의 A영역에서는 100% 운전으로 운전대수(용량)를 결정한다.In FIG. 2, since the ventilation operation is not required in the E region of less than 500 ppm of indoor pollution, the entire set of the first to fifth ventilation devices 10-1 to 10-5 is turned off, and D between 500 and 800 ppm is used. In the area, when the total capacity of the ventilation system is 100, it operates at 20%, 50% in the C area between 800 and 1000ppm, 80% in the B area between 1000 and 1200ppm, and 100% in the A area above 1200ppm. Determine the number (capacity)

그리고, 상기 결정된 운전대수(용량)에 따라 환기장치(10-1 ~ 10-5)를 운전시키기 위해 도 2에 도시한 환기장치(10-1 ~ 10-5)의 누적운전시간에 따라 최소의 누적운전시간을 갖는 환기장치(10-1 ~ 10-5)의 순서대로 운전순서를 결정한다(S140).And, in order to operate the ventilator (10-1 ~ 10-5) according to the determined number of driving capacity (capacity) of the minimum according to the cumulative operation time of the ventilator (10-1 ~ 10-5) shown in FIG. The operation sequence is determined in order of the ventilation apparatuses 10-1 to 10-5 having the cumulative operation time (S140).

따라서, 누적운전시간이 작은 환기장치(10-1 ~ 10-5)의 순서(제2환기장치→ 제3환기장치→ 제4환기장치→ 제1환기장치→ 제5환기장치)대로 운전순서가 결정되어 결정된 운전순서대로 실내 오염도에 따라 환기장치(10-1 ~ 10-5)가 운전을 시작하고(S150), 각 환기장치(10-1 ~ 10-5)의 제어기(10a-1 ~ 10a-5) 또는 중앙제어기(20)는 운전 중인 환기장치(10-1 ~ 10-5)의 현재 운전시간을 카운터한다(S160).Therefore, the operation sequence is in the order of the ventilation apparatuses 10-1 to 10-5 having a small cumulative operation time (second ventilation apparatus → third ventilation apparatus → fourth ventilation apparatus → first ventilation apparatus → fifth ventilation apparatus). According to the determined operation sequence, the ventilation apparatuses 10-1 to 10-5 start operation according to the indoor pollution degree (S150), and the controllers 10a-1 to 10a of the respective ventilation apparatuses 10-1 to 10-5. -5) or the central controller 20 counts the current operating time of the ventilator (10-1 ~ 10-5) in operation (S160).

이후, 환기장치(10-1 ~ 10-5)의 운전에 따라 실내공기가 환기되어 실내 오염도가 변화되었는가를 판단하여(S170), 실내 오염도가 변화되면 상기에서 결정된 운전순서의 반대 즉, 누적운전시간이 큰 환기장치(10-1 ~ 10-5)의 순서(제5환기장치→ 제1환기장치→ 제4환기장치→ 제3환기장치→ 제2환기장치)대로 운전 오프된다(S180).Thereafter, the indoor air is ventilated according to the operation of the ventilation apparatuses 10-1 to 10-5 to determine whether the indoor pollution degree is changed (S170). When the indoor pollution degree is changed, the reverse of the operation sequence determined above, that is, the cumulative operation The operation is turned off according to the order of the large ventilation apparatuses 10-1 to 10-5 (a fifth ventilation apparatus → a first ventilation apparatus → a fourth ventilation apparatus → a third ventilation apparatus → a second ventilation apparatus) (S180).

이때, 운전 오프전의 현재 운전시간에 체크된 이전의 누적운전시간을 더하여 각 환기장치의 새로운 누적운전시간을 산출하고 이를 저장한다(S190).At this time, a new cumulative operation time of each ventilator is calculated by adding the previous cumulative operation time checked to the current operation time before operation off (S190).

이후, 일정시간이 경과하여 실내 오염도가 환기운전이 필요한 재운전 시점인가를 판단하여(S200), 재운전이면 상기 S110으로 피드백되어 S110이하의 동작을 반복한다.Subsequently, after a predetermined time elapses, it is determined whether the indoor pollution degree is a re-operation point requiring ventilation operation (S200), and if it is re-operated, it is fed back to S110 and the operation of S110 or less is repeated.
