Description

선택적 필터링이 가능한 필터장치를 구비하는 공기순환장치{AIR EXCHANGE UNIT WITH THE FILTER}Air circulation system with filter device capable of selective filtering {AIR EXCHANGE UNIT WITH THE FILTER}

본 발명은 선택적 필터링이 가능한 필터장치를 구비하는 공기순환장치에 관한 것으로, 보다 상세하게는 외부로 부터 유입되는 공기 중에 미세먼지의 함유량이 많은 경우에는 선택적 필터링이 가능한 필터를 통해서 실내로 유입되도록 하고, 외부로 부터 유입되는 공기 중에 미세먼지의 함유량이 적어 공기질이 좋은 경우에는 굳이 필터를 거치지 않고 실내로 유입되도록 함으로써 모터동력을 줄일 수 있어 소비전력을 낮출 수 있고, 먼지제거 효율은 높아지며, 충분한 공기량을 실내로 유입할 수 있어 쾌적한 상태를 유지할 수 있는 선택적 필터링이 가능한 필터장치를 구비하는 공기순환장치이다.The present invention relates to an air circulation device having a filter device capable of selective filtering, and more specifically, when the content of fine dust is large in the air flowing from the outside, it is allowed to enter the room through a filter capable of selective filtering. , When the air quality is good because the content of fine dust is low in the air flowing from the outside, the motor power can be reduced by lowering the motor power by passing through the filter without going through the filter, and the efficiency of dust removal is high and sufficient air volume It is an air circulation device equipped with a filter device capable of selective filtering that can enter the room and maintain a comfortable state.

일반적으로, 최근 지어지는 건물은 에너지 절감을 위해 단열에 많은 노력을 기울이고 있으며, 건강을 위해 환기에 매우 많은 주의를 기울이고 있다. 따라서 단열과 환기를 모두 만족시키기 위해 실내공기와 외부공기를 환풍팬을 통해 강제로 흡입, 배출하도록 하고, 열교환소자를 이용해 공기의 청정 및 에너지 절감을 가능하게 하는 건물용 공기순환장치(공조장치)가 사용되는데, 상기한 건물용 공기순환장치는 공간의 효율적 활용을 위해 대개 천정에 설치되며 덕트를 통해 실내 공기와 실외 공기를 흡배기하도록 하고 있다. In general, recently built buildings are putting a lot of effort into insulation to save energy, and paying great attention to ventilation for health. Therefore, in order to satisfy both insulation and ventilation, the indoor air and external air are forcibly sucked and discharged through a ventilation fan, and a building air circulation device (air conditioning system) that enables clean and energy saving of air by using heat exchange elements Is used, the above-mentioned air circulation system for buildings is usually installed on the ceiling for efficient utilization of space, and is configured to intake and exhaust indoor and outdoor air through a duct.

그런데 이러한 종래 공기순환장치의 열교환소자의 일측면, 즉 실외공기가 유입되는 면에는 최근 미세먼지 문제로 인해 미세먼지제거 필터가 설치되어 미세먼지의 실내유입을 차단하도록 하고 있다.However, on one side of the heat exchange element of the conventional air circulation device, that is, the surface in which outdoor air is introduced, a fine dust removal filter is installed due to a recent problem of fine dust to block the indoor inflow of fine dust.

이처럼 미세먼지제거용 필터를 사용하게 되면 미세먼지는 제거할 수 있으나, 반대로 상기 필터가 공기의 유입을 방해하는 요소로 작용하게 된다.When a filter for removing fine dust is used as described above, the fine dust can be removed, but on the contrary, the filter acts as an element to prevent the inflow of air.

따라서 이 경우 대용량의 송풍기를 사용하여야 한다. 즉 공기순환장치의 내부에 설치되어 공기를 강제로 송풍시키는 송풍장치는 대개 비엘디씨(BLDC)모터를 사용하게 되는데, 상기 비엘디씨모터는 필터가 막힐 수록 더 큰 힘으로 회전하게 되어 많은 전력량을 필요로 하게 되고 이는 전기에너지의 낭비와 직결된다.Therefore, in this case, a large-capacity blower should be used. That is, a blower device installed inside the air circulation device for forcibly blowing air usually uses a BLDC motor. The BDC motor rotates with a greater force as the filter is blocked, and requires a large amount of power. This is directly related to the waste of electrical energy.

그런데 문제는 실외의 공기질이 항상 나쁜 것 만 아니라 미세먼지 주의보가 발령된 때만 나쁠 뿐이고 대개의 경우는 아주 나쁘지 않으며, 심지어 실외의 공기질이 실내의 공기질 보다도 좋은 경우도 왕왕있다. However, the problem is that outdoor air quality is not always bad, but it is only bad when a fine dust warning is issued, and in most cases it is not very bad, and even outdoor air quality is better than indoor air quality.

상기 필터장치(140)에 사용되는 필터(144)는 헤파필터(High Efficiency Particulate Air Filter)를 사용함이 바람직한데, 헤파필터는 공기 중의 먼지 등을 제거하는 에어필터로 등급에 따라 0.3㎛의 입자에 대해 85 ~ 99.975% 이상의 포집능력을 가지며 필터의 여과지는 주로 직경 1 ~ 10㎛ 이하의 유리 섬유로 되어있고, 입자의 크기에 따라 섬유조직에 의한 차단 및 충돌, 중력에 의한 입자침강, 입자의 브라운 운동, 정전기력에 의한 흡착 등을 이용하여 입자를 포집하는 구조를 갖는다. 이때 상기 필터(144)의 형상은 원통형상 또는 다각통 형상을 갖는 것이 바람직하다. The filter 144 used in the filter device 140 is preferably a High Efficiency Particulate Air Filter. The HEPA filter is an air filter that removes dust, etc., from air to 0.3 µm particles. It has a collection capacity of 85 to 99.975% or more, and the filter paper of the filter is mainly composed of glass fibers with a diameter of 1 to 10 µm or less, depending on the size of the particles, it is blocked and collided by fiber tissue, particle sedimentation by gravity, and brown of particles. It has a structure to collect particles using motion, adsorption by electrostatic force, and the like. At this time, the shape of the filter 144 preferably has a cylindrical shape or a polygonal shape.

이때 지지부재(141)는 필터(144)의 양측을 커버해야 하는데, 상기 필터(144)는 공지의 필터천을 굴곡지게 접은 구조여서 측면을 커버하지 않으면 공기가 새버리기 때문이다. 또한 지지부재(141)는 상기 필터(144)가 지속적으로 제 형태를 유지하도록 하기 위해서도 필요한 구성이다. At this time, the support member 141 should cover both sides of the filter 144, because the filter 144 is a well-known structure of a folded filter cloth that does not cover the side, so air leaks. In addition, the support member 141 is a configuration necessary for the filter 144 to maintain its shape continuously.

또 상기 지지부재(141)의 일측에는 모터지지구(141a)가 돌출되도록 형성되는데, 상기 모터지지구(141a)에는 모터(142)가 모터축이 일측으로 돌출되도록 결합되고 상기 모터축에는 댐퍼(143)가 결합되어 회전구동되도록 한다.In addition, a motor support 141a is formed to protrude on one side of the support member 141. A motor 142 is coupled to the motor support 141a such that the motor shaft protrudes to one side, and a damper ( 143) are combined to drive rotation.

이때 통공(144a)의 밀폐력을 더 좋게하고 댐퍼(143)의 회전구동을 보다 안정적으로 할 수 있도록 상기 모터지지구(141a)는 통공(144a)으로 부터 연장되는 원통형상의 플랜지로 구성됨이 바람직하다. 물론 상기 플랜지의 경우 내측직경은 통공(144a)의 직경과 동일하게 형성됨이 바람직하다. At this time, the motor support 141a is preferably composed of a cylindrical flange extending from the through hole 144a so that the sealing force of the through hole 144a is better and the rotational driving of the damper 143 can be more stable. Of course, in the case of the flange, the inner diameter is preferably formed to be the same as the diameter of the through hole (144a).

상기 모터지지구(141a)의 일측에 모터축이 관통할 수 있는 축공을 천공하여 모터축을 끼운다음 모터(142)를 플랜지에 나사 등과 같은 체결구(미도시)로 고정하게 된다. 상기 모터지지구(141a) 내측으로 돌출된 모터축에는 댐퍼(143)의 축(142a)이 끼워져 댐퍼(143)가 모터(142)의 구동에 의해 회전가능토록 구성된다. 물론 상기 댐퍼(143)는 첵밸브와 같은 작용을 할 수 있도록 원형으로 형성되고, 외측의 직경이 통공(144a)의 직경에 최대한 근접하게 형성함이 바람직하다. On one side of the motor support 141a, a shaft hole through which a motor shaft can penetrate is drilled to fit the motor shaft, and then the motor 142 is fixed to a flange with a fastener (not shown) such as a screw. The shaft 142a of the damper 143 is fitted to the motor shaft protruding inside the motor support 141a so that the damper 143 is rotatable by driving the motor 142. Of course, it is preferable that the damper 143 is formed in a circular shape to act as a check valve, and the outer diameter is formed as close as possible to the diameter of the through hole 144a.

이는 공기의 차단 효율은 좋게 하면서 회전은 가능해야 하기 때문이다. 상기 댐퍼(143)는 회전운동을 할 수도 있지만 공지의 다양한 수단에 의해 나비의 날개처럼 여닫히는 방식을 구현할 수도 있다. 이의 구현은 당업자에게 있어 어려운 것이 아니다.This is because the air blocking efficiency should be good and rotation must be possible. The damper 143 may rotate, but it may implement a method of opening and closing like the wings of a butterfly by various means known in the art. Its implementation is not difficult for those skilled in the art.

상기 필터(144)의 형상은 원통형상 또는 다각형상의 통으로 이루어지는 것이 바람직한데, 이는 댐퍼(143)가 통공(144a)의 일측을 막고 있는 상태라면, 즉 실외의 공기질이 좋지 못해 필터(144)를 통과해야할 필요성이 있을 때는 실외의 공기가 필터(144)를 통해서 실내로 유입되도록 해야하기 때문이다.The shape of the filter 144 is preferably made of a cylindrical or polygonal cylinder, which is a condition in which the damper 143 is blocking one side of the through hole 144a, that is, the air quality of the outdoor air is not good and the filter 144 passes through the filter 144. This is because when there is a need to do so, outdoor air must be introduced into the room through the filter 144.

물론 반대로 실외의 공기질이 좋아서 그대로 실내로 유입시키고자 할 때는 댐퍼(143)를 열게 되면 실외의 공기들은 필터(144)를 통과하는 것보다 통공(144a)을 그대로 통과하는 것이 쉬워 실외의 공기를 필터(144)를 거치지 않고 실내로 유입되도록 유도할 수 있게 된다.Of course, on the contrary, when the air quality of the outdoor is good, and when the damper 143 is opened when it is intended to flow into the room, the outdoor air is easier to pass through the through hole 144a than the filter 144 to filter the outdoor air. It can be induced to enter the room without going through (144).

본 발명에 있어서 보조함체(170)은 함체(150)가 본 발명 공기순환장치(100)의 일측에만 형성되는 경우에는 균형감을 잃어 미관상 좋지 못하기 때문에 이를 방지하기 위해 형성되는 구조이다.In the present invention, the auxiliary housing 170 is a structure formed to prevent this when the enclosure 150 is formed on only one side of the air circulation device 100 of the present invention because it loses a sense of balance and is not good in appearance.
