본 발명은 환기시스템 및 환기시스템의 댐퍼 제어방법에 관한 것으로 특히 2개의 실내기가 하나의 전열교환기와 연결되는 2실 환기시스템 및 환기시스템의 댐퍼 제어방법에 관한 것이다.The present invention relates to a ventilation system and a damper control method of the ventilation system, and more particularly, to a two-room ventilation system and a damper control method of the ventilation system in which two indoor units are connected to one electrothermal exchanger.

밀폐된 공간의 공기는 생명체의 호흡에 의해 시간이 지나면서 이산화탄소의 함량이 증가하게 되어 생명체의 호흡에 지장을 주게 된다. 따라서, 사무실 등과 같이 협소한 공간에 많은 사람이 머물게 되는 경우 실내의 오염된 공기를 실외의 신선한 공기로 대체해 줄 필요가 있다. 이때 통상적으로 사용되는 것이 환기시스템인데, 특히 최근 대두되고 있는 새집증후군 즉, 새집에서 발생하는 포름알데히드(HCHO) 및 휘발성 유기화합물(VOC)을 제거하기 위해 환기시스템의 필요성이 더욱 부각되고 있는 실정이다.The air in an enclosed space increases the carbon dioxide content over time due to the breathing of living things, which interferes with the breathing of living things. Therefore, when many people stay in a narrow space such as an office, it is necessary to replace the indoor air with fresh air. In this case, the ventilation system is commonly used. In particular, the necessity of the ventilation system to remove the form house (HCHO) and the volatile organic compound (VOC) generated in the new house syndrome, that is, the new house, is emerging. .

이러한 환기시스템에서 실외공기가 실내에 유입됨으로써 발생하는 열손실을 줄이기 위해 전열교환기를 대부분 사용하는데, 근래에는 사용되는 전열교환기의 수를 줄이기 위해 하나의 전열교환기에 2개의 실내기를 연결하여 사용하는 2실 환기시스템이 등장하였다.In such a ventilation system, most of the heat exchangers are used to reduce heat loss caused by the inflow of outdoor air into the room. In recent years, two indoor units are connected to one heat exchanger to reduce the number of heat exchangers used. Room ventilation systems have emerged.

이러한 2실 환기시스템에서 환기 운전이 시작되면 운전하고자 하는 각 실내기에 마련된 댐퍼가 열리고 전열교환기 및 실내기에 각각 마련된 송풍팬이 구동되어 환기가 이루어진다. 만약, 2개의 실내기 중 1개의 실내기만 운전되는 경우, 운 전되는 실내기측의 댐퍼는 열리고 운전되지 않는 실내기측의 댐퍼는 닫혀 1개의 실내기만 단독 운전된다. When the ventilation operation is started in the two-chamber ventilation system, dampers provided in each indoor unit to be operated are opened, and ventilation fans are driven by driving the blower fans provided in the heat exchanger and the indoor unit, respectively. If only one indoor unit of the two indoor units is operated, the damper on the indoor unit side to be operated is opened and only one indoor unit is operated by closing the damper on the indoor unit side which is not operated.

이와 같은 2실 환기시스템의 실내기와 연결되는 급기덕트 및 배기덕트에는 유로를 개폐하기 위한 다수개의 댐퍼가 설치되는데, 상기 댐퍼가 실내기 측에 설치되어 있기 때문에 전열교환기측에서 발생시킨 풍압이 운전되지 않는 실내기의 댐퍼에 까지 걸리게 되며, 이로 인해 운전하지 않는 실내기 측에서 소음이 발생하였다. The air supply duct and the exhaust duct connected to the indoor unit of the two-chamber ventilation system are provided with a plurality of dampers for opening and closing the flow path. Since the dampers are installed at the indoor unit, the wind pressure generated by the heat exchanger side is not operated. The damper of the indoor unit is caught, which causes noise from the indoor unit that is not operating.

또한, 각 실내기의 급기덕트 및 배기덕트에는 유로를 개폐하기 위해 각각의 댐퍼가 사용되었으므로 많은 댐퍼의 사용으로 인해 환기시스템의 제품원가도 상승하게 되는 문제점이 있었다.In addition, since each damper is used to open and close the flow paths of the air supply duct and the exhaust duct of each indoor unit, the product cost of the ventilation system also increases due to the use of many dampers.

다음으로 상기와 같이 구성된 환기시스템의 동작에 대해 살펴본다.Next, look at the operation of the ventilation system configured as described above.

먼저 제 1실내기(10a)가 운전 중이고 제 2실내기(10b)가 운전 중이 아니라면, 마이크로 프로세서(미도시)는 스텝모터(60)를 회전시켜 급기댐퍼(51a)를 Z에 위치시켜 제 2급기덕트(30b)를 폐쇄한다. 그러면, 제 2실내기(10b)로 통하는 제 2유로(32)는 급기댐퍼(51a)에 의해 차단되어 제 2실내기(10b)로는 외기가 도입될 수 없게 된다.First, if the first chamber 10a is in operation and the second chamber 10b is not in operation, the microprocessor (not shown) rotates the step motor 60 to position the air supply damper 51a at Z to supply the second air supply duct. Close 30b. Then, the second flow passage 32 leading to the second chamber 10b is blocked by the air supply damper 51a, so that outside air cannot be introduced into the second chamber 10b.

다음으로 제 2실내기(10b)가 운전 중이고 제 1실내기(10a)가 운전 중이 아니라면, 마이크로 프로세서는 스텝모터(60)를 회전시켜 급기댐퍼(51a)를 Y에 위치시켜 제 1급기덕트(30a)를 폐쇄한다 그러면, 제 1실내기(10a)로 통하는 제 1유로(31)는 급기댐퍼(51a)에 의해 차단되어 제 1실내기(10a)로는 외기가 도입될 수 없게 된다.Next, if the second indoor unit 10b is in operation and the first indoor unit 10a is not in operation, the microprocessor rotates the step motor 60 to position the air supply damper 51a at Y, thereby providing the first air supply duct 30a. Then, the first passage 31 leading to the first chamber 10a is blocked by the air supply damper 51a, so that no outside air can be introduced into the first chamber 10a.

다음으로 제 1실내기(10a)와 제 2실내기(10b)가 모두 운전 중이라면 마이크로 프로세서는 스텝모터(60)를 회전시켜 급기댐퍼(51a)를 X에 위치시킨다. 그러면, 제 1실내기(10a)로 통하는 제 1유로(31)와 제 2실내기(10b)로 통하는 제 2유로(32)가 모두 개방되어 제 1, 2실내기(10a,10b) 모두로 외기가 공급되게 된다.Next, if both the first chamber 10a and the second chamber 10b are in operation, the microprocessor rotates the step motor 60 to position the air supply damper 51a at X. Then, both the first passage 31 leading to the first indoor chamber 10a and the second passage 32 leading to the second indoor chamber 10b are opened to supply the outside air to both the first and second indoor chambers 10a and 10b. Will be.

이와 같이, 급기댐퍼(51a)를 급기덕트 분지관(50a) 내부의 제 1급기덕트(30a)와 제 2급기덕트(30b)의 경계부에 설치하고 급기댐퍼(51a)를 회전시켜 제 1, 2실내기(10a,10b) 중 운전하는 실내기와 연결된 급기덕트는 개방하고, 운전하지 않는 실내기와 연결된 급기덕트는 폐쇄함으로써 운전하는 실내기에만 외기를 급기할 수 있다. In this way, the air supply damper 51a is installed at the boundary between the first air supply duct 30a and the second air supply duct 30b in the air supply duct branch pipe 50a, and the air supply damper 51a is rotated so that the first and second air supply dampers 51a are rotated. The air supply duct connected to the indoor unit to operate among the indoor units 10a and 10b may be opened, and the air supply duct connected to the indoor unit not to operate may be closed to supply the outdoor air only to the indoor unit to operate.

이와 같이 실내기(10a,10b)로 급기되는 외기를 차단하는 급기댐퍼(51a)가 급 기덕트 분지관(50a)에 설치됨으로써, 실내기(10a,10b) 측에서 발생하는 소음을 줄일 수 있다. 또한, 하나의 급기댐퍼(51a)를 사용하여 두개의 급기덕트(30a,30b)를 개폐할 수 있으므로 댐퍼 수를 줄여 환기시스템의 원가를 절감할 수 있다. In this way, the air supply damper 51a for blocking the outside air supplied to the indoor units 10a and 10b is installed in the air supply duct branch pipe 50a, thereby reducing noise generated at the indoor units 10a and 10b. In addition, since two air supply ducts (30a, 30b) can be opened and closed using one air supply damper (51a) it is possible to reduce the number of dampers to reduce the cost of the ventilation system.

배기덕트 합지관(50b) 내부의 제 1유로(31)와 제 2유로(32)의 경계부에도 배기댐퍼(51b)가 설치되는데, 배기댐퍼(51b)의 동작은 급기댐퍼(51a)의 동작과 동일하므로 그에 대한 설명은 생략한다. An exhaust damper 51b is also provided at the boundary between the first flow passage 31 and the second flow passage 32 in the exhaust duct lamination pipe 50b. The operation of the exhaust damper 51b is similar to that of the air supply damper 51a. Since it is the same, description thereof is omitted.

상기에서 설명한 것은 본 발명에 따른 환기시스템 및 환기시스템의 댐퍼 제어밥법을 실시하기 위한 하나의 실시예에 불과한 것으로, 본 발명은 상술한 일 실시예에 한정되지 않고 본 발명의 기술적 사상 내에서 당 분야의 통상을 지식을 가진 자에 의하여 여러 가지 변형이 가능하다.What has been described above is only one embodiment for implementing the damper control rice method of the ventilation system and the ventilation system according to the present invention, the present invention is not limited to the above-described embodiment, but within the technical scope of the present invention Many modifications are possible to those skilled in the art.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 환기시스템 및 환기시스템의 댐퍼 제어방법에 의하면 실내기로 급기되는 외기를 차단하는 급기댐퍼 및 실내기로부터 배기되는 내기를 차단하는 배기댐퍼를 각각 분지관 및 합지관에 설치함으로써, 실내기 측에서 발생하는 소음을 줄일 수 있다. As described in detail above, according to the damper control method of the ventilation system and the ventilation system according to the present invention, a branch pipe and a laminated pipe each include an air supply damper that blocks external air supplied to the indoor unit and an exhaust damper that blocks internal air exhausted from the indoor unit. By installing in the unit, noise generated on the indoor unit side can be reduced.

또한, 하나의 급기댐퍼를 사용하여 두 개의 급기덕트를 개폐할 수 있으며, 하나의 배기댐퍼를 사용하여 두 개의 배기덕트를 개폐할 수 있으므로 환기시스템에 사용되는 댐퍼 수를 줄일 수 있으므로 원가를 절감할 수 있다.In addition, two air supply ducts can be opened and closed using one air supply damper, and two air exhaust ducts can be opened and closed using one exhaust damper, thereby reducing the number of dampers used in the ventilation system. Can be.
