Description

저소음 전열교환장치{Low-noise total heat exchanger}Low-noise total heat exchanger}

본 발명은 저소음 전열교환장치에 관한 것으로서, 더욱 상세하게는 천장에 일직선으로 길게 형성된 라인타입의 급기판으로 전열교환기의 팬소음이 유입되지 않도록 상기 전열교환기 내부에 급기유로를 지그재그 형태로 형성하고 급기유로에 다수의 충돌편 및 흡음재를 마련함으로써, 충돌편 및 흡음재를 거치면서 팬소음이 상쇄되고, 실내로 팬소음이 직접 유입되지 않는 저소음 전열교환장치에 관한 것이다.The present invention relates to a low-noise total heat exchange device. More specifically, the air supply path is formed in a zigzag shape inside the total heat exchanger to prevent the fan noise of the total heat exchanger from entering the line-type air supply plate formed in a straight line on the ceiling. This relates to a low-noise total heat exchange device that provides a plurality of impact pieces and sound-absorbing materials in the flow path, so that fan noise is canceled out while passing through the impact pieces and sound-absorbing materials, and fan noise does not flow directly into the room.

일반적으로 전열교환기는 실내에서 배기하는 열(온열·냉열)에 의하여 외기에서 들어오는 공기를 따뜻하게(또는 차갑게) 해 주기 위한 열교환기로서, 이러한 전열교환기를 사용하면 창문 등의 개방을 통해서 실내를 환기시키는 경우에는 외부공기가 실내로 유입되며 실내의 냉, 난방된 공기가 쉽게 손실되거나 내부공기가 급격하게 변화하는 문제와 함께 열에너지가 손실되는 문제점이 해소된다.In general, a total heat exchanger is a heat exchanger that warms (or cools) the air coming from the outside air by the heat (hot/cold heat) exhausted from the room. When such a total heat exchanger is used, it ventilates the room by opening windows, etc. In this case, when outside air flows into the room, the problem of the indoor cooled or heated air being easily lost or the indoor air changing rapidly and heat energy being lost are solved.

상기 전열교환기는 급기쪽과 배기쪽에 송풍팬이 설치되는데, 실내 천장에 마련된 급기구가 원통형의 디퓨져 타입일 경우 팬소음이 크지 않으나, 일직선의 라인타입으로 구성되면 급기구가 커지게 되므로 팬소음이 실내로 많이 유입되는 문제점이 발생된다.The total heat exchanger has blowing fans installed on the air supply side and exhaust side. If the air supply port provided on the indoor ceiling is a cylindrical diffuser type, the fan noise is not large, but if it is configured as a straight line type, the air supply port becomes large, so the fan noise is high. A problem arises with a lot of water being introduced indoors.

본 발명자의 특허 제2019702호는 급기 및 배기용 덕트의 한쪽 면이 실내로 노출되어 천장면과 일치되게 하되, 노출된 면이 탈착되도록 함으로써, 덕트 내부를 주기적으로 청소할 수 있으며, 급기쪽 덕트에는 폴리프로필렌이나 부직포로 구성된 튜브형 필터가 장착되어 공기를 한 번 더 여과시키고 주기적으로 교체 가능하고, 특히 급기판 및 배기판이 일렬로 길게 라인타입으로 시공되기 때문에 공기 흐름이 넓은 면적으로 균일하게 분포되고 한곳에 집중되지 않으므로 실내를 쾌적하게 할 수 있는 공기정화시스템을 제안한 바 있다.The present inventor's patent No. 2019702 states that one side of the air supply and exhaust duct is exposed to the room and matches the ceiling surface, but the exposed side is detachable, so that the inside of the duct can be cleaned periodically, and the air supply side duct is equipped with a poly duct. A tubular filter made of propylene or non-woven fabric is installed to filter the air once more and can be replaced periodically. In particular, the air supply and exhaust plates are constructed in a long line, so the air flow is evenly distributed over a large area and concentrated in one place. Since this does not work, an air purification system that can make the interior comfortable has been proposed.

그러나 본 발명자의 특허는 전열교환기를 거친 바람이 실내의 급기판에서 넓은 면적으로 퍼져서 실내를 빠르고 균일하게 환기시킬 수 있으나, 상기 급기판이 넓은 면적으로 개방되기 때문에 팬소음이 실내로 많이 유입되어 학교나 도서관 같은 공공장소에는 사용이 부적합해지는 등의 기술적인 문제점이 있었다.However, the present inventor's patent states that the wind that has passed through the heat exchanger spreads over a large area from the indoor air supply plate, allowing the room to be quickly and evenly ventilated. However, because the air supply plate is open to a large area, a lot of fan noise flows into the room, making it possible to ventilate the room quickly and uniformly. There were technical problems that made it unsuitable for use in public places such as libraries.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 천장에 일직선으로 길게 형성된 라인타입의 급기판으로 전열교환기의 팬소음이 유입되지 않도록 상기 전열교환기 내부에 급기유로를 지그재그 형태로 형성하고 급기유로에 다수의 충돌편 및 흡음재를 마련함으로써, 급기유로와 충돌편을 거치면서 팬소음이 상쇄되고, 실내로 팬소음이 직접 유입되지 않는 저소음 전열교환장치를 제공함에 있다.The present invention was developed in consideration of conventional problems. The purpose of the present invention is to form a zigzag air supply path inside the heat exchanger to prevent the fan noise of the heat exchanger from flowing into a line-type air supply plate formed in a straight line on the ceiling. By forming a plurality of collision pieces and sound-absorbing materials in the air supply passage, fan noise is canceled out while passing through the air supply passage and collision pieces, and a low-noise total heat exchange device is provided that does not directly introduce fan noise into the room.

이를 위하여 본 발명 한 실시예는 본체 내부에 전열교환기가 구비되고, 상기 본체의 실외측에는 실외측급기구 및 실외측배기구가 구비되고, 실내측에는 실내측급기구 및 실내측배기구가 구비되며, 상기 실내측급기구와 실외측급기구 및 실내측배기구와 실외측배기구는 상기 전열교환기에서 대각선으로 교차되게 연결되어서 실내공기와 외기가 열교환되도록 한 저소음 전열교환장치에 있어서, 상기 실외측급기구와 전열교환기 사이에 급기송풍팬이 구비되고, 상기 실외측배기구와 전열교환기 사이에 배기송풍팬이 구비되며; 상기 급기송풍팬과 전열교환기에 형성되는 급기유로는 다수의 격벽을 통하여 지그재그 형태로 유로가 형성되고, 상기 격벽에는 다수의 충돌편이 서로 엇갈리게 구비되어서 팬소음이 충돌되어 상쇄되도록 한 특징이 있다.For this purpose, an embodiment of the present invention is provided with a total heat exchanger inside the main body, an outdoor side supply device and an outdoor side exhaust port are provided on the outdoor side of the main body, an indoor side supply device and an indoor side exhaust device are provided on the indoor side, and the indoor side supply device is provided. In the low-noise total heat exchanger in which the outdoor side air supply, the indoor side exhaust, and the outdoor side exhaust are connected diagonally to the heat exchanger to exchange heat with indoor air and outdoor air, a supply air blowing fan is provided between the outdoor side air supply and the total heat exchanger. is provided, and an exhaust blowing fan is provided between the outdoor side exhaust port and the total heat exchanger; The air supply flow path formed in the air supply blower fan and the total heat exchanger is formed in a zigzag shape through a plurality of partition walls, and the partition walls are provided with a plurality of collision pieces alternately, so that fan noise is offset by collision.

본 발명에 따르면 급기송풍팬이 실외쪽에 구비되고, 상기 급기송풍팬과 전열교환기 사이에 형성되는 급기유로가 지그재그 형태로 절곡되어서 바람이 열교환기로 직접 향하지 않는다. 또한 상기 급기유로에는 다수의 충돌편 및 흡음재가 엇갈리게 형성되어서 이들 충돌편 및 흡음재에 바람이 충돌되는 과정에서 팬소음이 상쇄된다. 따라서 천장에 길이방향으로 형성되는 라인타입의 급기판으로 팬소음이 유입되지 않으므로 학교나 도서관 갖은 공공장소에서 팬소음이 실내로 확산되지 않는 등의 이점이 있다.According to the present invention, a supply air blowing fan is provided on the outdoor side, and the air supply flow path formed between the air supply blowing fan and the total heat exchanger is bent in a zigzag shape so that the wind does not go directly to the heat exchanger. In addition, a plurality of collision pieces and sound-absorbing materials are formed alternately in the air supply passage, so that fan noise is canceled out in the process of wind colliding with these collision pieces and sound-absorbing materials. Therefore, since fan noise does not flow into the line-type air supply plate formed longitudinally on the ceiling, there are advantages such as fan noise not spreading indoors in public places such as schools and libraries.

도 2는 본 발명 한 실시예의 전열교환장치의 단면도1 is a diagram showing the installation state of the total heat exchange device in one embodiment of the present invention.
Figure 2 is a cross-sectional view of a total heat exchange device according to an embodiment of the present invention.

도 1 내지 도 2는 본 발명 한 실시예의 전열교환장치로써, 직육면체의 본체(10) 내부에 마름모꼴 형태로 전열교환기(11)가 배치된다. 상기 전열교환기(11)는 급기통로와 배기통로가 서로 엇갈리게 다단으로 적층되어서 실내공기와 실외공기가 각 통로를 지나면서 열교환되는 일반적인 방식이며, 상기 본체(10)의 실외측에는 실외측급기구(12)와 실외측배기구(13)가 각각 구비되고, 실내측에는 실내측급기구(14)와 실내측배기구(15)가 각각 구비되며, 상기 실외측급기구(12)와 실내측급기구(14) 및 상기 실외측배기구(13)와 실내측배기구(15)는 서로 엇갈리게 대각선 방향으로 본체(10)에 구비된다.1 and 2 show a total heat exchange device according to an embodiment of the present invention, in which a total heat exchanger 11 is arranged in a diamond shape inside a rectangular body 10. The total heat exchanger (11) is a general method in which the supply and exhaust passages are stacked in multiple stages alternating with each other, so that indoor air and outdoor air exchange heat while passing through each passage, and an outdoor side air supply port (12) is installed on the outdoor side of the main body (10). and an outdoor side exhaust port 13 are provided, respectively, and on the indoor side, an indoor side supply port 14 and an indoor side exhaust port 15 are provided, and the outdoor side supply port 12, the indoor side supply port 14, and the outdoor side are provided. The exhaust port 13 and the indoor exhaust port 15 are provided in the main body 10 in a diagonal direction, alternating with each other.

상기 실외측배기구(13)와 전열교환기(11) 사이에는 배기송풍팬(21)이 구비되며, 상기 실외측급기구(12)와 전열교환기(11) 사이에는 급기송풍팬(20)이 구비된다. 또한 상기 급기송풍팬(20)과 전열교환기(11) 사이의 공간에는 다수의 격벽(31)을 통하여 급기유로(30)가 지그재그 형태로 구비된다. 그리고 상기 각 격벽(31)에는 서로 엇갈리게 다수의 충돌편(32)이 돌출되어서 급기유로(30)가 일직선으로 통하지 않고 미로처럼 복잡해지도록 해준다. 또한 급기유로(30)에서 바람이 유턴되는 지점에는 흡음재(33)가 구비되어서 팬소음이 흡수되도록 해준다. 그리고 전열교환기(11)와 실내측급기구(14) 사이의 본체(10) 내벽에도 흡음재(33)가 구비되어서 소음을 흡수한다.An exhaust blowing fan 21 is provided between the outdoor side exhaust port 13 and the total heat exchanger 11, and a supply air blowing fan 20 is provided between the outdoor air supply port 12 and the total heat exchanger 11. In addition, in the space between the air supply blowing fan 20 and the total heat exchanger 11, an air supply flow path 30 is provided in a zigzag shape through a plurality of partition walls 31. In addition, a plurality of collision pieces 32 protrude from each of the partition walls 31 in an alternating manner so that the air supply passage 30 does not run in a straight line but becomes complicated like a maze. In addition, a sound absorbing material (33) is provided at the point where the wind makes a U-turn in the air supply passage (30) to absorb fan noise. In addition, a sound-absorbing material 33 is provided on the inner wall of the main body 10 between the total heat exchanger 11 and the indoor air supply device 14 to absorb noise.

또한 상기 실내측급기구(14) 및 실내측배기구(15)는 플랙시블한 덕트를 통하여 실내 천장에 구비되는 급기판(40) 및 배기판(41)과 연결된다. 상기 급기판(40) 및 배기판(41)은 일직선으로 길게 형성되는 라인타입으로써, 다수의 구멍이 천공되어서 바람이 통하도록 구성되며, 상기 급기판(40) 내부에는 폴리프로필렌이나 부직포로 구성된 튜브형 필터가 장착되어 실외공기를 여과시킨다.In addition, the indoor side air supply device 14 and the indoor side exhaust device 15 are connected to the air supply plate 40 and exhaust plate 41 provided on the indoor ceiling through a flexible duct. The air supply plate 40 and the exhaust plate 41 are of a line type formed in a straight line and have a plurality of holes drilled to allow air to pass through. Inside the air supply plate 40 is a tubular filter made of polypropylene or non-woven fabric. is installed to filter outdoor air.

이처럼 구성된 본 발명 한 실시예의 전열교환장치는 급기송풍팬(20)이 실외측에 설치되어서 팬소음이 전열교환기(11)를 거치면서 상쇄되는 이점이 있으며, 특히 급기유로(30)가 지그재그로 형성되고 다수의 충돌편(32) 및 흡음재(33)로 인하여 소음이 한번 더 상쇄되므로 저소음으로 급기가 진행된다.The total heat exchange device of one embodiment of the present invention configured in this way has the advantage that the air supply blowing fan 20 is installed on the outdoor side, so that the fan noise is canceled out while passing through the total heat exchanger 11. In particular, the air supply path 30 is formed in a zigzag shape. And since the noise is canceled out once again by the multiple collision pieces 32 and the sound absorbing material 33, the air supply proceeds with low noise.

이러한 본 발명 한 실시예의 급배기과정은 다음과 같다. 상기 본체(10)에 구비된 실외측급기구(12) 및 실외측배기구(13)는 실외쪽으로 향하고, 실내측급기구(14) 및 실내측배기구(15)는 덕트를 통하여 급기판(40) 및 배기판(41)과 연결된다. 따라서 실외측급기구(12)와 전열교환기(11) 사이에 구비된 급기송풍팬(20)이 작동되면 외기가 실외측급기구(12)를 통하여 본체(10) 내부로 유입된다.The supply and exhaust process of this embodiment of the present invention is as follows. The outdoor side air supply port 12 and the outdoor side exhaust port 13 provided in the main body 10 are directed toward the outdoors, and the indoor side air supply port 14 and the indoor side exhaust port 15 are connected to the air supply plate 40 and the exhaust plate through a duct. It is connected to (41). Accordingly, when the air supply blowing fan 20 provided between the outdoor side air supply device 12 and the heat exchanger 11 is operated, outdoor air flows into the main body 10 through the outdoor side air supply device 12.

본체(10)로 유입된 외기는 급기유로(30)를 따라 전열교환기(11) 쪽으로 향하게되는데, 상기 급기유로(30)는 다수의 격벽(31)을 통하여 지그재그 형태로 구성되고, 각 격벽(31)에는 서로 엇갈리게 충돌편(32)이 형성되기 때문에 급기유로(30)가 미로처럼 복잡해져서 외기가 충돌편(32)을 거치면서 와류 형태로 빠져나가게 되며, 이 과정에서 팬소음이 충돌편(32)에서 상쇄되는 효과가 있다. 또한 바람의 방향이 180도 바뀌는 유턴지점에는 흡음재(33)가 구비되기 때문에 소음이 흡음재(33)에 흡수 소멸되며, 나머지 소음은 전열교환기(11)를 거치면서 상쇄된다.The outdoor air flowing into the main body 10 is directed toward the total heat exchanger 11 along the air supply passage 30. The air supply passage 30 is configured in a zigzag shape through a plurality of partition walls 31, and each partition 31 ), because the collision pieces 32 are formed alternately with each other, the air supply passage 30 becomes complicated like a maze, and the outside air passes through the collision pieces 32 and escapes in the form of a vortex. In this process, the fan noise is generated by the collision pieces 32. ) has an offsetting effect. In addition, since a sound-absorbing material 33 is provided at the U-turn point where the wind direction changes 180 degrees, noise is absorbed and extinguished by the sound-absorbing material 33, and the remaining noise is offset by passing through the total heat exchanger 11.

따라서 급기송풍팬(20)의 작동으로 외기가 실외측급기구(12)에서 급기유로(30)를 통하여 전열교환기(11)를 통과하는 동안 팬소음이 대부분 상쇄되기 때문에 일직선으로 형성되어 넓은 면적으로 개방되는 급기판(40)에서 외기가 실내로 도입되는 과정에서 팬소음이 줄어든다. 그리고 실내공기는 배기판(41)에서 실내측배기구(15)를 거쳐 전열교환기(11)로 향한 뒤 배기송풍팬(21)을 거쳐 실외측배기구(13)로 배출되면서 열교환된다Therefore, most of the fan noise is canceled while the outside air passes from the outdoor side air supply port 12 through the air supply passage 30 through the heat exchanger 11 due to the operation of the air supply blowing fan 20, so it is formed in a straight line and opened to a large area. Fan noise is reduced in the process of introducing outside air into the room through the air supply plate 40. In addition, the indoor air flows from the exhaust plate 41 through the indoor exhaust port 15 to the total heat exchanger 11 and then is discharged to the outdoor exhaust port 13 through the exhaust blower fan 21, thereby exchanging heat.
