본 발명은 폐열회수 환기장치에 관한 것으로서, 더욱 상세하게는 역류방지용 덕트플랜지 개폐장치를 구비하는 폐열회수환기장치에 관한 것이다.The present invention relates to a waste heat recovery ventilator, and more particularly, to a waste heat recovery ventilator having a duct flange opening and closing device for preventing backflow.

일반적으로, 폐열회수 환기장치는 실내공기를 실외로 배출되는 실내공기와 먼저 열교환시킨 다음 실내로 공급하는 것이다.In general, the waste heat recovery ventilator is to heat the indoor air with the indoor air discharged to the outside first and then supply the indoor air.

도 1에 도시된 바와 같이, 종래기술에 따른 폐열회수 환기장치(1)는 실내공기가 어느 정도 오염되었을 때 배기팬(25)에 전원이 인가되면서 실내공기가 배기흡입구(12)를 통해 덕트(10)로 유입된 다음, 열교환기(30)의 배기통로를 지나 배기배출구(23)를 통해 실외로 배출된다. 이와 동시에, 급기팬(15)에 전원이 인가되면서 신선한 실외공기가 급기흡입구(11)를 통해 덕트(10)로 유입된 다음, 열교환기(30)의 급기통로(미도시)를 지나 급기배출구(13)를 통해 실내로 유입된다.As shown in FIG. 1, the waste heat recovery ventilator 1 according to the related art is provided with power to an exhaust fan 25 when indoor air is contaminated to some extent while indoor air is ducted through the exhaust inlet 12. 10), and then is discharged to the outside through the exhaust outlet 23 through the exhaust passage of the heat exchanger (30). At the same time, while supplying power to the air supply fan 15, fresh outdoor air flows into the duct 10 through the air supply inlet 11, and then passes through an air supply passage (not shown) of the heat exchanger 30 to supply air to the air supply outlet ( 13) is introduced into the room.

이 때, 열교환기(30)를 지나는 실내공기와 실외공기는 열교환판을 통해 열교환하게 된다. 이 과정을 상술하면, 열교환기(30)에서 일어나는 열교환은 급기되는 실외공기와 배기되는 실내공기 사이에 일어나는 현열교환과, 실내공기 또는 실외공기 중 고온의 공기가 노점온도(dew point temp.) 이하의 상태가 되면서 생성된 응축수에 의한 잠열교환으로 이루어진다. 이러한 열교환 방식의 환기장치의 경우, 실내가 냉방 또는 난방 분위기일 때 급기되는 실외공기가 실내공기와 1차적으로 열교환된 다음 실내로 유입됨에 따라, 실내온도의 급격한 상승이나 하강을 방지할 수 있다.At this time, the indoor air and the outdoor air passing through the heat exchanger 30 will exchange heat through the heat exchange plate. Specifically, the heat exchange occurring in the heat exchanger 30 includes sensible heat exchange between the supplied outdoor air and the exhausted indoor air, and high temperature air in the indoor or outdoor air is below the dew point temp. It is made of latent heat exchange by the condensate produced in the state of. In the case of the heat exchange type ventilation device, the outdoor air supplied when the room is cooled or heated is primarily heat-exchanged with the indoor air and then introduced into the room, thereby preventing a rapid rise or fall of the room temperature.

아울러, 폐열회수 환기장치(1)의 급기흡입구(11), 급기배출구(13), 배기흡입구(12), 및 배기배출구(23)에는 각각 공기의 이송경로인 연결 덕트와 결합하기 위한 덕트플랜지(11a,13a,12a,23a)가 구비된다. 최근 들어서는 고층건물에 폐열회수 환기장치(1)를 적용하는 것이 일반적인데, 이 폐열회수 환기장치(1)에 결합된 연결 덕트(3)는 대부분 건물의 외부로 노출이 되어 있었다.In addition, the air supply inlet 11, air supply outlet 13, exhaust inlet 12, and exhaust outlet 23 of the waste heat recovery ventilator (1), respectively, a duct flange for coupling with a connecting duct, which is a transport path of air ( 11a, 13a, 12a, 23a are provided. In recent years, it is common to apply a waste heat recovery ventilator (1) to a high-rise building, and the connecting ducts (3) coupled to the waste heat recovery ventilator (1) have been exposed to the outside of most buildings.

그러나 이러한 종래기술은 건물의 외부로 연결 덕트(3)가 노출된 상태이기 때문에, 폐열회수 환기장치(1)의 급기팬(15)이 가동하지 않았음에도 연결 덕트(3)를 통해 실내로 외기가 유입되는 공기 역류현상이 빈번하였으며, 특히 외풍이 심한 지역에서는 이러한 공기 역류현상이 더욱 빈번하여 소비자들의 제품 신뢰성을 떨어뜨리는 문제점이 있었다.However, since the connection duct 3 is exposed to the outside of the building, the conventional technology does not allow the outdoor air to enter the room through the connection duct 3 even though the air supply fan 15 of the waste heat recovery ventilator 1 is not operated. Inflow of air backflow was frequent, especially in areas with high drafts, such air backflow was more frequent, which lowered the product reliability of consumers.

아울러, 건물 중에서 공동 연도(미도시)를 사용하는 경우에는 각 연결 덕트(3)가 이 공동연도와 직접 연결된 상태이므로, 각 세대에서 배출되는 오염된 공기(예를 들면, 음식조리 냄새 등)가 연결 덕트(3)를 따라 폐열회수 환기장치(1)를 거쳐 다른 세대로 유입되는 공기 역류현상이 빈번하여 사용자들에게 불쾌감을 유발하는 문제점이 있었다.In addition, when a common year (not shown) is used in a building, each connecting duct 3 is directly connected to the common year, so that polluted air (for example, cooking smell, etc.) discharged from each household is discharged. Along with the connection duct (3) through the waste heat recovery ventilator (1) there is a problem that the air flow back to the other generation is often causing inconvenience to users.

상기한 문제점을 해결하기 위하여 본 발명은 공기가 연결 덕트를 통해 역류하는 현상을 방지할 수 있도록 하는 역류방지용 덕트플랜지 개폐장치를 구비하는 폐열회수환기장치를 제공하는 것을 목적으로 한다.In order to solve the above problems, an object of the present invention is to provide a waste heat recovery ventilator having a reverse flow prevention duct flange opening and closing device to prevent the phenomenon of air flowing back through the connecting duct.
