본 발명은 폐열회수형 환기장치에 관한 것으로서, 더욱 상세하게는 유입되는 외부공기의 분진농도에 따라 능동적으로 여과능력을 조절할 수 있는 폐열회수형 환기장치에 관한 것이다. The present invention relates to a waste heat recovery type ventilator, and more particularly, to a waste heat recovery type ventilator capable of actively adjusting the filtration capacity according to the dust concentration of the incoming air.

폐열회수형 환기장치는 사람의 호흡 등의 요인에 의해 오염된 실내공기를 신선한 실외공기로 교환해주기 위한 용도로 사용하는 장치로서, 실내외의 온도차가 심한 경우 냉난방의 효율이 현저히 감소하는 것을 방지하기 위하여 유입되는 실외공기와 배출되는 실내공기 간의 간접적인 열교환이 장치의 내부에서 일어나도록 하여 열손실을 줄여줄 수 있도록 한 것이다. The waste heat recovery type ventilation device is used to replace indoor air contaminated by factors such as human breathing with fresh outdoor air. In order to prevent a significant decrease in the efficiency of heating and cooling, when the temperature difference between indoors and outdoors is severe. Indirect heat exchange between the incoming outdoor air and the discharged indoor air occurs inside the device to reduce heat loss.

이와 같은 폐열회수형 환기장치는 신선한 공기를 실내공간에 공급하기 위하여 분진에 의해 오염된 외부공기를 여과할 용도의 부직포 필터나 염화비닐 필터와 같은 일반적인 여과수단을 내장하여 실내공간에 분진에 의한 오염이 제거된 신선한 공기를 공급하고자 한 형태로 제공되기도 한다. Such a waste heat recovery type ventilation device includes a non-woven filter or a vinyl chloride filter for filtering external air contaminated by dust in order to supply fresh air to the indoor space. It may also be provided in one form to supply this removed fresh air.

그러나, 이상과 같은 폐열회수형 환기장치는 황사 등을 포함하는 경우와 같이 분진에 의한 오염 정도가 심한 경우에는 일반적인 여과수단만으로는 오염물질을 완전히 제거하는데 한계가 있는 실정이다.However, the waste heat recovery type ventilation device as described above has a limit to completely remove contaminants only by general filtration means when the degree of contamination by dust is severe, such as when it includes yellow sand.

이와 관련하여, 근래 들어 중국에서 발생하는 황사의 정도가 날로 심각해 짐과 더불어 해로운 물질을 다량 함유하는 특징을 보이고 이를 직접적으로 체험해 본 소비자의 요구에 따라, 일반적인 여과수단에 비해 현저히 큰 여과능력을 구비하는 헤파필터와 같은 고성능 여과수단을 포함하는 형태의 폐열회수형 환기장치가 개시 된 바 있다.In this regard, in recent years, the degree of yellow dust occurring in China has become increasingly severe, and according to the needs of consumers who have experienced and directly experienced a large amount of harmful substances, they have significantly greater filtration capacity than general filtration means. There has been disclosed a waste heat recovery type ventilation device including a high performance filtration means such as a hepa filter provided.

그러나, 헤파필터는 통기조직이 매우 조밀하여 여과능력은 우수한 반면, 압력손실이 상대적으로 커서 요구되는 송풍량을 만족시키기 위해서는 상대적으로 대용량의 송풍기를 채택해야만 하는 문제를 필연적으로 동반하게 되며, 이는 또한 에너지소비효율을 저하시키는 문제를 야기한다.However, the HEPA filter has a very tight ventilation structure and excellent filtration ability, but the pressure loss is relatively large, which inevitably leads to the problem of adopting a relatively large blower to satisfy the required air volume. It causes the problem of lowering the consumption efficiency.

그리고, 이상과 같은 종래기술에 따른 폐열회수형 환기장치는 분진농도에 따라 능동적으로 대응하지 못함에 따라, 부직포 필터나 염화비닐 필터와 같은 일반적인 여과수단으로도 충분한 대응이 가능한 경우에도 상당히 고가인 헤파필터가 계속 여과작용을 수행할 수밖에 없는 구조임에 따라, 고가의 헤파필터를 빈번하게 교체해야하는 주어야 하는 비경제성을 내포하는 문제점이 있는 실정이다. In addition, the waste heat recovery type ventilation apparatus according to the prior art as described above does not actively cope with the dust concentration, so that even if a general filtration means such as a nonwoven filter or a vinyl chloride filter is sufficiently expensive, hepa As the filter has a structure inevitably carrying out filtration, there is a problem in that it is necessary to replace the expensive HEPA filter frequently, which imposes an economical cost.

이상과 같은 종래기술의 문제점을 해소하기 위하여 발명한 것으로서, In order to solve the problems of the prior art as described above,

본 발명의 목적은, 일반적인 여과수단과 여과능력이 우수한 고성능 필터수단을 모두 포함하되 유입되는 실외공기의 분진농도에 따라 두 여과수단 중 어느 하나 또는 모두가 능동적으로 여과작용을 수행할 수 있도록 하여, 바람직한 여과성능을 실현함과 더불어 에너지소비효율을 향상시킬 수 있도록 하는 조절가능한 여과능력을 갖는 폐열회수형 환기장치를 제공하는 것이다. An object of the present invention, including both the general filtration means and high-performance filter means excellent in filtration capacity, so that any one or both of the filtration means to perform the filtration actively depending on the dust concentration of the outdoor air introduced, It is to provide a waste heat recovery type ventilation apparatus having an adjustable filtration ability to realize the desired filtration performance and to improve the energy consumption efficiency.

이하, 본 발명의 바람직한 실시 예를 첨부되는 도면을 참조하여 더욱 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

도 1은 본 발명의 제 1 실시 예에 따른 폐열회수형 환기장치를 도시한 개략적 구성도이다. 1 is a schematic configuration diagram showing a waste heat recovery type ventilator according to a first embodiment of the present invention.

본 발명의 제 1 실시 예에 따른 폐열회수형 환기장치는 유입되는 실외공기에 포함된 분진의 양에 대응하여 여과능력을 조절할 수 있다. The waste heat recovery type ventilator according to the first embodiment of the present invention may adjust the filtration capacity according to the amount of dust included in the introduced outdoor air.

본 발명의 제 1 실시 예에 따른 폐열회수형 환기장치는, 도 1에 도시한 바와 같이, 서로 교차하는 형태로 배치되는 것으로서, 배출구(3) 측에 급기팬(10)이 설치되는 급기덕트(5)와 배출구(13) 측에 배기팬(20)이 설치되는 배기덕트(15)를 갖는 케비닛(1)을 포함한다. 그리고, 실내로 유입되는 공급공기와 실외로 배출되는 배출공기 사이의 간접적인 열교환이 일어나도록, 급기덕트(5)와 연통되는 다수의 급기통로(미도시)와 배기덕트(15)와 연통되는 다수의 배기통로(미도시)를 갖는 폐열교환기(30)가 케비닛(1) 내부의 급기덕트(5)와 배기덕트(15)가 교차하는 위치에 설치된다. 또한, 급기덕트(5) 내부에 유동경로를 횡단하도록 설치되어 분진을 여과하는 1차 여과필터(40)와, 급기덕트(5) 내부에 유동경로를 횡단하거나 유동경로와 나란하도록 배치형태의 전환이 가능하게 설치되어 필요에 따라 선택적으로 1차 여과필터(40)를 통과한 외부공기로부터 분진을 제거하는 2차 여과필터(50)를 포함한다.In the waste heat recovery type ventilator according to the first embodiment of the present invention, as illustrated in FIG. 1, the waste heat recovery type ventilator is disposed to cross each other, and an air supply duct in which the air supply fan 10 is installed on the outlet 3 side ( 5) and a cabinet 1 having an exhaust duct 15 in which an exhaust fan 20 is provided on the discharge port 13 side. In addition, a plurality of air passages (not shown) communicated with the air supply duct 5 and a plurality of air ducts 15 communicating with the air supply duct 5 so that indirect heat exchange between the supply air introduced into the indoor air and the air discharged to the outside occurs. A waste heat exchanger 30 having an exhaust passage (not shown) is installed at a position where the air supply duct 5 and the exhaust duct 15 intersect in the cabinet 1. In addition, the primary filtration filter 40 is installed to traverse the flow path inside the air supply duct 5 and the arrangement of the arrangement so as to cross the flow path or parallel with the flow path inside the air supply duct 5. It is installed so as to include a secondary filtration filter 50 to selectively remove dust from the outside air passed through the primary filtration filter 40 as needed.

1차 여과필터(40)는 판상으로 형성된 부직포 필터 또는 염화비닐 필터 등과 같이 여과능력이 상대적으로 적은 필터가 사용되는 것이 바람직하며, 폐열교환 기(30)에 형성된 급기통로의 흡입구 측에 설치되어 유동경로를 횡단하는 형태로 배치된다. 그리고, 2차 여과필터(50)는 여과능력이 우수한 판상으로 형성된 헤파필터가 사용되는 것이 바람직하며, 폐열교환기(30)에 형성된 급기통로의 배출구 측에 판상으로 형성되는 2차 여과필터의 일측 변 부분이 회전축의 역할을 수행하는 힌지고정방식으로 고정되어 여닫이 방식으로 배치형태가 전환될 수 있도록 설치된다.The primary filtration filter 40 is preferably a filter having a relatively low filtration capacity, such as a nonwoven fabric filter or a vinyl chloride filter formed in a plate shape, and is installed on the inlet side of the air supply passage formed in the waste heat exchanger 30 to flow. It is arranged to cross the path. In addition, the secondary filtration filter 50 is preferably a hepa filter formed in a plate shape with excellent filtration ability, one side of the secondary filtration filter formed in a plate on the outlet side of the air supply passage formed in the waste heat exchanger (30). The part is fixed in a hinged manner, which serves as a rotating shaft, and is installed so that the arrangement can be switched in and out.

여기서, 2차 여과필터(50)는 구동모듈에 의해 배치형태가 전환되는 것으로서, 구동모듈은 구동모터(60)를 포함할 수 있다. 구동모터(60)는 제어부에서 인가하는 신호에 따라 2차 여과필터(50)의 배치형태가 유동경로를 횡단하거나 유동경로와 나란하도록 전환하게 된다. Here, the secondary filtration filter 50 is that the arrangement is switched by the drive module, the drive module may include a drive motor (60). The driving motor 60 is switched so that the arrangement of the secondary filtration filter 50 crosses the flow path or is parallel to the flow path according to a signal applied from the controller.

더불어, 급기덕트(5)의 유입구(7) 측에 분진의 농도를 감지하기 위한 분진농도감지수단으로서, 분진계수기(particle counter: 70)와 같은 센서가 설치된다. 이때, 제어부(미도시)는 분진계수기(70)의 검출 값을 입력받아 설정된 값과 비교한 다음 구동모듈에 적절한 제어신호를 인가하여 구동모터(60)를 통해 2차 여과필터(50)의 배치형태를 전환하고, 2차 여과필터(50)의 배치형태에 따라 급기팬(10)의 회전수를 제어하게 된다.In addition, as a dust concentration detecting means for detecting the concentration of dust at the inlet 7 side of the air supply duct 5, a sensor such as a particle counter 70 is provided. At this time, the controller (not shown) receives the detection value of the dust counter 70 and compares it with the set value, and then applies the appropriate control signal to the drive module to arrange the secondary filtration filter 50 through the drive motor 60. The shape is switched, and the rotation speed of the air supply fan 10 is controlled according to the arrangement form of the secondary filtration filter 50.

이상과 같은 본 발명의 제 1 실시 예에 따른 폐열회수형 환기장치는 분진계수기(70)가 포함되어 실시간으로 유입되는 실외공기에 포함된 분진의 농도를 파악할 수 있으며, 검출 값에 따라 2차 여과필터(50)의 사용 여부를 결정하게 된다. 즉, 분진에 의한 오염도가 낮은 경우에는 2차 여과필터(50)가 유동경로와 나란하게 배치된 상태에서 유동경로를 횡단하는 1차 여과필터(40)만이 여과작용을 수행하도록 하고, 분진에 의한 오염도가 높아지면 구동모터(60)를 통해 2차 여과필터(50)를 선회시킴으로써 그 배치형태가 유동경로를 횡단하도록 전환하여 1차 여과필터(40)에 의한 여과작용에 뿐만 아니라 여과능력이 우수한 2차 여과필터(50)에 의한 여과작용이 수행될 수 있도록 하여, 유입되는 실외공기에 포함된 분진이 충분히 제거될 수 있도록 한다. 이때, 통기조직이 매우 미세하여 압력손실의 증가가 수반되는 헤파필터를 2차 여과필터로 사용함에 따라, 2차 여과필터(50)에 의한 여과작용이 수행되는 경우에는 급기팬(10)의 회전수를 증가시켜 필요한 유량을 확보할 수 있도록 한다. 여기서, 급기팬(10)의 회전수를 제어하기 위하여, 브러시리스 직류모터( Brushless Direct Current Motor; 이하, BLDC 모터)를 사용하여 회전수를 제어하거나, 별도의 인버터를 적용하여 회전수를 제어하거나, 탭제어모터를 사용하여 단계별로 회전수를 제어할 수 있도록 한다. The waste heat recovery type ventilator according to the first embodiment of the present invention as described above may include a dust counter 70 to determine the concentration of dust included in outdoor air introduced in real time, and according to the detection value, secondary filtration. The use of the filter 50 is determined. In other words, when the degree of contamination by dust is low, only the primary filtration filter 40 crossing the flow path in the state in which the secondary filtration filter 50 is disposed in parallel with the flow path performs the filtration, and When the degree of contamination increases, by turning the secondary filtration filter 50 through the drive motor 60, the arrangement is switched to cross the flow path, so that not only the filtration action by the primary filtration filter 40 but also excellent filtration ability. Filtration by the secondary filtration filter 50 can be performed, so that the dust contained in the incoming outdoor air can be sufficiently removed. At this time, when the hepatic filter is very fine and the pressure loss is accompanied by an increase in pressure loss, and the secondary filter is used as the secondary filter, rotation of the air supply fan 10 is performed. Increase the number to ensure the required flow rate. Here, in order to control the rotation speed of the air supply fan 10, a brushless direct current motor (hereinafter referred to as a BLDC motor) to control the rotation speed, or by applying a separate inverter to control the rotation speed Using a tap control motor, the rotation speed can be controlled step by step.

정리하면, 분진에 의한 오염도가 낮아 1차 여과필터(40)만으로도 충분한 분진제거효과를 얻을 수 있는 일반적인 경우에는, 2차 여과필터(50)를 유동경로와 나란하게 배치되도록 전환하고, 2차 여과필터(50)에 의한 압력손실의 영향이 발생하지 않음에 따라 낮은 회전수로 급기팬(10)이 구동되도록 함으로써, 소비전력을 줄여 운전비용을 절감할 수 있도록 한다. 그리고, 분진에 의한 오염도가 높아져서 1차 여과필터(40)만으로는 충분한 분진제거효과를 얻을 수 없는 경우에는, 2차 여과필터(50)가 유동경로를 횡단하도록 전환하고, 2차 여과필터(50)에 의한 압력손실의 영향을 감안하여 높은 회전수로 급기팬(10)이 구동되도록 함으로써, 충분한 분진제 거효과와 더불어 소기의 환기효과를 얻을 수 있도록 한다. In summary, in the general case where the degree of contamination due to dust is low and a sufficient dust removal effect can be obtained by the primary filtration filter 40 alone, the secondary filtration filter 50 is switched to be arranged in parallel with the flow path, and the secondary filtration is performed. As the influence of the pressure loss by the filter 50 does not occur, the air supply fan 10 is driven at a low rotational speed, thereby reducing power consumption and reducing operating costs. In addition, when the degree of contamination due to dust is high and only the primary filtration filter 40 cannot obtain a sufficient dust removal effect, the secondary filtration filter 50 is switched to cross the flow path, and the secondary filtration filter 50 is performed. In consideration of the pressure loss caused by the air supply fan 10 is driven at a high rotational speed, it is possible to obtain a sufficient dust removal effect and the desired ventilation effect.

이와 같이, 2차 여과필터(50)가 상시 여과작용을 수행하는 것이 아니라 필요한 경우에만 선택적으로 여과작용을 수행함에 따라, 2차 여과필터(50)의 교체주기가 늘어날 수 있으며, 따라서 2차 여과필터(50)로 사용되는 헤파필터가 고가임을 감안했을 때 상당한 운전비용절감효과를 얻을 수 있게 된다. As such, as the secondary filtration filter 50 selectively performs filtration only when necessary rather than performing filtration constantly, the replacement cycle of the secondary filtration filter 50 may be increased, and thus, secondary filtration. Considering that the HEPA filter used as the filter 50 is expensive, significant operating cost reduction effect can be obtained.

마찬가지로, 1차 여과필터(40')는 판상으로 형성된 부직포 필터 또는 염화비닐 필터 등과 같이 여과능력이 상대적으로 적은 필터가 사용되는 것이 바람직하며, 2차 여과필터(50)는 여과능력이 상대적으로 우수한 판상으로 형성된 헤파필터가 사용되는 것이 바람직하다. 또한, 1차 여과필터(40')는 폐열교환기(30)에 형성된 급기통로의 흡입구 측에, 그리고 2차 여과필터(50)는 폐열교환기(30)에 형성된 급기통로의 배출구 측에, 각각의 일측 변 부분이 회전축의 역할을 수행하는 힌지고정방식으로 고정되어 여닫이 방식으로 배치형태가 전환될 수 있도록 설치된다.Similarly, the primary filtration filter 40 ′ is preferably a filter having a relatively low filtration capability such as a nonwoven fabric filter or a vinyl chloride filter formed in a plate shape, and the secondary filtration filter 50 has a relatively good filtration capability. It is preferable to use a HEPA filter formed in a plate shape.

One side portion is fixed in a hinged manner to play the role of the rotating shaft is installed so that the arrangement can be switched in the opening and closing manner.

여기서, 1차 여과필터(40')와 2차 여과필터(50)는 모두 각각의 구동모듈에 의해 배치형태가 전환되는 것으로서, 각 구동모듈은 구동모터(45)(60)를 포함한다. 구동모터(45)(60)는 제어부에서 인가하는 신호에 따라 1차 여과필터(40')와 2차 여과필터(50)의 배치형태가 유동경로를 횡단하거나 유동경로와 나란하도록 필요에 따라 전환하게 된다. Here, the primary filtration filter 40 ′ and the secondary filtration filter 50 are all arranged by the respective driving modules, and each driving module includes driving motors 45 and 60. The drive motors 45 and 60 are switched as necessary so that the arrangement of the primary filtration filter 40 ′ and the secondary filtration filter 50 crosses the flow path or is parallel to the flow path according to a signal applied from the control unit. Done.

더불어, 급기덕트(5)의 유입구(7) 측에 분진의 농도를 감지하기 위한 분진농도감지수단으로서, 분진계수기(70)와 같은 센서가 설치된다. 이때, 제어부는 분진계수기(70)의 검출 값을 입력받아 설정된 값과 비교한 다음, 각 구동모듈에 적절한 제어신호를 인가하여 각 구동모터(45)(60)를 통해 1차 여과필터(40') 및 2차 여과필터(50)의 배치형태를 전환하고, 1차 여과필터(40')와 2차 여과필터(50)의 배치형 태에 따라 급기팬(10)의 회전수를 제어하게 된다.In addition, as the dust concentration detecting means for detecting the concentration of dust on the inlet (7) side of the air supply duct (5), a sensor such as a dust counter 70 is provided. At this time, the control unit receives the detection value of the dust counter 70 and compares it with the set value, and then applies the appropriate control signal to each drive module through each drive motor 45, 60 through the primary filtration filter 40 ' ) And the arrangement of the secondary filtration filter 50, and the rotation speed of the air supply fan 10 is controlled according to the arrangement of the primary filtration filter 40 ′ and the secondary filtration filter 50. .

아울러, 배기덕트(15) 내부에 유동경로를 횡단하도록 설치되어 분진을 여과하는 또 하나의 1차 여과필터(80)를 포함하여, 실외로 배출되는 공기에 포함된 분진을 제거하도록 할 수 있다. 이 1차 여과필터(80) 역시 판상으로 형성된 부직포 필터 또는 염화비닐 필터 등과 같이 여과능력이 상대적으로 적은 필터가 사용되는 것이 바람직하며, 폐열교환기(30)에 형성된 배기통로의 흡입구 측에 설치되어 유동경로를 횡단하는 형태로 배치된다.In addition, the exhaust duct 15 may include another primary filtration filter 80 installed to traverse the flow path to remove dust, thereby removing dust contained in the air discharged to the outside. The primary filtration filter 80 is also preferably a filter having a relatively low filtration capacity, such as a nonwoven fabric filter or a vinyl chloride filter formed in a plate shape, and is installed on the inlet side of the exhaust passage formed in the waste heat exchanger 30 to flow. It is arranged to cross the path.

이상과 같은 본 발명의 제 2 실시 예에 따른 폐열회수형 환기장치는 분진계수기(70)가 포함되어 실시간으로 유입되는 실외공기에 포함된 분진의 농도를 파악할 수 있으며, 검출 값에 따라 1차 여과필터(40') 및 2차 여과필터(50) 각각의 사용 여부를 결정하게 된다. 즉, 분진에 의한 오염도가 낮은 경우에는 2차 여과필터(50)가 유동경로와 나란하게 배치된 상태에서 유동경로를 횡단하도록 배치되는 1차 여과필터(40')만이 여과작용을 수행하는 제1단계 운전모드로 운전하고, 분진에 의한 오염도가 어느 정도 높은 경우에는 각 구동모터(45)(60)를 통해 1차 여과필터(40')와 2차 여과필터(50)를 각각 선회시킴으로써 1차 여과필터(40')는 유동경로에 나란하게 배치되도록 전환하고 2차 여과필터(60)는 그 배치형태가 유동경로를 횡단하도록 전환하여 여과능력이 우수한 2차 여과필터(60)만이 여과작용을 수행하는 제2단계 운전모드로 운전하여, 상대적으로 향상된 여과작용으로 인하여 유입되는 실외공기에 포함된 분진이 충분히 제거될 수 있도록 한다. 또한, 분진에 의한 오염도가 매우 높은 경우에는, 구동모터(45)를 통해 1차 여과필터(40')를 선회시킴으로써 1차 여과필터(40') 또한 2차 여과필터(50)와 마찬가지로 그 배치형태가 유동경로를 횡단하도록 전환하여 순차적으로 1차 여과필터(40')와 여과능력이 우수한 2차 여과필터(50) 모두에 의한 여과작용이 수행될 수 있도록 하는 제3단계 운전모드로 운전하여, 더욱더 향상된 여과작용으로 인하여 유입되는 실외공기에 포함된 분진이 충분히 제거될 수 있도록 한다. 다시 말해, 본 발명의 제 2 실시 예에 따른 폐열회수형 환기장치는 유입되는 실외공기에 포함된 분진의 농도에 따라 더욱 분화된 형태로 조절되는 여과능력을 갖게 된다.The waste heat recovery type ventilator according to the second embodiment of the present invention as described above may include the dust counter 70 to determine the concentration of dust included in the outdoor air introduced in real time, and according to the detection value, the primary filtration. It is determined whether each of the filter 40 'and the secondary filtration filter 50 is used. That is, when the degree of contamination due to dust is low, the first filtration filter 40 'disposed only to cross the flow path in a state where the secondary filtration filter 50 is disposed in parallel with the flow path performs the filtration action. When operating in the step operation mode and the degree of contamination due to dust is high to some extent, the primary filtration filter 40 'and the secondary filtration filter 50 are pivoted through the respective driving motors 45 and 60, respectively. The filtration filter 40 'is switched so as to be arranged side by side in the flow path, and the secondary filtration filter 60 is switched so that the arrangement form crosses the flow path so that only the secondary filtration filter 60 having excellent filtration ability performs filtration. By operating in the second stage operation mode to be performed, it is possible to sufficiently remove the dust contained in the incoming outdoor air due to the relatively improved filtration action. In addition, when the pollution degree by dust is very high, the primary filtration filter 40 'is also arranged similarly to the secondary filtration filter 50 by turning the primary filtration filter 40' through the drive motor 45. By switching the shape to cross the flow path, it is operated in the third operation mode to sequentially perform the filtration by both the primary filtration filter 40 'and the secondary filtration filter 50 having excellent filtration ability. In addition, the improved filtration ensures that the dust contained in the incoming outdoor air is sufficiently removed. In other words, the waste heat recovery type ventilator according to the second embodiment of the present invention has a filtration capacity that is controlled in a more differentiated form according to the concentration of dust included in the introduced outdoor air.

이와 같이 3단계로 여과능력이 조절됨과 동시에, 각 단계별로 압력손실에 의한 영향이 상이함에 따라 급기팬(10)의 회전수를 적절하게 조절하여 필요한 유량을 확보할 수 있도록 한다. 즉, 급기팬(10)의 회전수를 제어하기 위하여, BLDC 모터를 사용하여 회전수를 제어하거나, 별도의 인버터를 적용하여 회전수를 제어하거나, 탭제어모터를 사용하여 단계별로 회전수를 제어할 수 있도록 한다. 다시 말해, 통기조직이 성긴 부직포 필터 또는 염화비닐 필터를 사용한 1차 여과필터(40')만이 여과작용을 수행하는 경우에는 낮은 회전수의 기본 회전수로 급기팬(10)을 구동하고, 통기조직이 매우 미세하여 압력손실의 증가가 수반되는 헤파필터를 사용한 2차 여과필터(50)만이 여과작용을 수행하는 경우에는 급기팬(10)의 회전수를 한 단계 증가시켜 필요한 유량을 확보할 수 있도록 하고, 1차 여과필터(40')와 2차 여과필터(50)가 모두 여과작용을 수행하는 경우에는 급기팬(10)의 회전수를 한 단계 더 증가시켜 필요한 유량을 확보할 수 있도록 한다. As described above, the filtration capacity is adjusted in three stages, and the influence of the pressure loss on each stage is different, so that the required flow rate can be secured by appropriately adjusting the rotation speed of the air supply fan 10. That is, in order to control the rotation speed of the air supply fan 10, the rotation speed is controlled using a BLDC motor, a separate inverter is applied to control the rotation speed, or the rotation speed is controlled step by step using a tap control motor. Do it. In other words, in the case where only the primary filtration filter 40 'using the nonwoven fabric filter or vinyl chloride filter having the ventilation structure performs the filtration action, the air supply fan 10 is driven at the basic rotation speed of the low rotation speed, and the ventilation structure When only the secondary filtration filter 50 using the HEPA filter, which is very fine and accompanied by an increase in pressure loss, performs filtration, the rotational speed of the air supply fan 10 is increased by one step to secure a required flow rate. In addition, when both the primary filtration filter 40 'and the secondary filtration filter 50 perform a filtration action, the rotation speed of the air supply fan 10 is increased by one step to ensure a required flow rate.

정리하면, 분진에 의한 오염도가 낮아 1차 여과필터(40')만으로도 충분한 분진제거효과를 얻을 수 있는 일반적인 경우에는, 2차 여과필터(50)를 유동경로와 나란하게 배치되도록 전환하고, 2차 여과필터(50)에 의한 압력손실의 영향이 발생하지 않음에 따라 낮은 회전수로 급기팬(10)이 구동되도록 함으로써, 소비전력을 줄여 운전비용을 절감할 수 있도록 한다. 그리고, 분진에 의한 오염도가 높아져서 1차 여과필터(40')만으로는 충분한 분진제거효과를 얻을 수 없으나 2차 여과필터(50)만으로도 충분한 분진제거효과를 얻을 수 있는 경우에는, 1차 여과필터(40')는 유동경로와 나란하도록 그리고 2차 여과필터(50)는 유동경로를 횡단하도록 전환하고, 2차 여과필터(50)에 의한 증가한 압력손실의 영향을 감안하여 한 단계 높은 회전수로 급기팬(10)이 구동되도록 함으로써, 충분한 분진제거효과를 얻을 수 있도록 한다. 더불어, 분진에 의한 오염도가 더욱 높아져서 2차 여과필터(50)만으로 충분한 분진제거효과를 얻을 수 없는 경우에는, 1차 여과필터(40') 또한 2차 여과필터(50)와 마찬가지로 유동경로를 횡단하도록 전환하고, 1차 여과필터(40')와 2차 여과필터(50)가 동시에 여과작용을 수행함에 따라 더욱 증가하는 압력손실의 영향을 감안하여 한 단계 더 높은 회전수로 급기팬이 구동되도록 함으로써, 이 경우에도 충분한 분진제거효과를 얻을 수 있도록 한다.In summary, in the general case where the degree of contamination due to dust is low and a sufficient dust removal effect can be obtained with only the primary filtration filter 40 ', the secondary filtration filter 50 is switched to be arranged in parallel with the flow path, and the secondary As the influence of the pressure loss by the filtration filter 50 does not occur, the air supply fan 10 is driven at a low rotational speed, thereby reducing power consumption and reducing operating costs. In addition, when the degree of contamination due to dust is increased and sufficient dust removing effect is not obtained only by the primary filtration filter 40 ', but only when the secondary filtration filter 50 alone can obtain sufficient dust removing effect, the primary filtration filter 40 ') Is parallel to the flow path and the secondary filtration filter 50 to cross the flow path, taking into account the effect of increased pressure loss by the secondary filtration filter 50, the air supply fan at a higher speed By driving (10), a sufficient dust removal effect can be obtained. In addition, when the degree of contamination due to dust is further increased and sufficient dust removal effect cannot be obtained only by the secondary filtration filter 50, the primary filtration filter 40 'also crosses the flow path like the secondary filtration filter 50. And the air supply fan is driven at a higher speed in consideration of the effect of increasing pressure loss as the primary filtration filter 40 'and the secondary filtration filter 50 simultaneously perform filtration. Thus, even in this case, it is possible to obtain a sufficient dust removal effect.

이와 같이, 1차 여과필터(40')와 2차 여과필터(50)가 상시 여과작용을 수행하는 것이 아니라 필요한 경우에만 선택적으로 여과작용을 수행함에 따라, 한정된 수명을 갖는 각 여과필터가 제 효용을 다할 수 있도록 함과 더불어 교체주기가 늘어날 수 있도록 한다. 따라서 기본적으로 2차 여과필터로 사용되는 헤파필터가 고 가임을 감안했을 때 2차 여과필터의 적절한 사용으로 인한 운전비용절감효과 뿐만 아니라, 1차 여과필터로 사용되는 부직포 필터나 염화비닐 필터가 저가임을 감안하더라도 1차 여과필터의 적절한 사용에 따른 운전비용절감효과 또한 얻을 수 있게 되며, 결국 상당한 운전비용절감효과를 얻을 수 있도록 한다. As such, the primary filtration filter 40 'and the secondary filtration filter 50 do not always perform filtration but selectively perform filtration only when necessary, so that each filtration filter having a limited lifetime is effective. In addition to this, the replacement cycle can be extended. Therefore, considering that the HEPA filter used as the secondary filtration filter is expensive, basically, the operation cost saving effect due to the proper use of the secondary filtration filter is reduced, and the nonwoven fabric filter or the vinyl chloride filter used as the primary filtration filter is inexpensive. Considering this, it is also possible to obtain an operation cost reduction effect according to the proper use of the primary filtration filter, so that a significant operation cost reduction effect can be obtained.

이상과 같은 본 발명에 따른 조절가능한 여과능력을 갖는 폐열회수형 환기장치를 제공함으로써, 분진에 의한 오염도에 따라 기본적인 1차 여과필터와 여과능력이 우수한 2차 여과필터의 가변적인 조합에 의해 적절한 정도의 여과작용이 수행될 수 있도록 하며, 동시에 여과필터에 의한 압력손실에 의한 영향을 감안하여 단계별로 적절한 회전수로 급기팬이 가동될 수 있도록 하여, 상황에 따른 충분한 분진제거효과와 더불어 소비전력의 감소와 여과필터의 교체주기 연장에 따른 운전비용절감효과를 얻을 수 있도록 한다. By providing a waste heat recovery type ventilation apparatus having an adjustable filtration capacity according to the present invention as described above, the appropriate degree by the variable combination of the basic primary filtration filter and the secondary filtration filter excellent in filtration capacity according to the pollution degree by dust Filtration can be performed, and at the same time, the air supply fan can be operated at an appropriate rotational speed in consideration of the effect of pressure loss by the filtration filter. Reduce operating costs by reducing and extending the replacement cycle of the filtration filter.
