Spaces are becoming increasingly airtight or closed.
이러한 변화에 따라 오늘날 거의 모든 건물에는 외부의 신선한 공기를 내부로 공급하고, 내부의 공기를 외부로 배출시키는 공기순환기 또는 공조시스템이 설치되고 있고, 이러한 공기순환기에는 에너지절약을 위하여 전열 교환부를 구비한 폐열 회수형 공기순환기가 주로 사용되고 있다.According to this change, almost all buildings today are equipped with an air circulator or air conditioning system that supplies fresh air from the outside to the inside and exhausts the inside air to the outside. A waste heat recovery type air circulator is mainly used.
한편, 미세먼지는 여러 가지 복합한 성분을 가진 대기 중 부유물질로서, 자동차, 공장, 화력 발전소등에서 발생하고 있고, 인간의 생활에 따라 일반 실내에서도 발생하고 있다.On the other hand, fine dust is a suspended matter in the atmosphere with various complex components, and is generated in automobiles, factories, thermal power plants, etc., and is also generated indoors according to human life.
이러한 미세먼지에 장기간 노출된 경우 호흡기 및 심혈관계 질환이 발생할 수 있고, 미세먼지에는 바이러스 등이 묻어 있어 코로나 19와 같은 전염병 확산의 원인이 될 수 있어 사회적인 문제가 되고 있다..Long-term exposure to such fine dust can cause respiratory and cardiovascular diseases, and the fine dust contains viruses, etc., which can cause the spread of infectious diseases such as Corona 19, which is a social problem.
대한민국 공개특허공보 공개번호 10-2020-0004520호에는 환기구와 급기구가 하우징; 상기 하우징의 내부에 배치되며, 외기구로 흡입된 공기와 상기 환기구로 흡입된 공기를 열교환시키는 전열교환소자를 포함하여 에너지를 절약하는 공기순환기 가 개시되어 있다.In Korean Patent Laid-Open Publication No. 10-2020-0004520, a ventilation port and an air supply port are provided in a housing; Disclosed is an air circulator that saves energy, which is disposed inside the housing and includes a total heat exchange element for exchanging heat between air sucked through an external device and air sucked through the ventilation port.
또한 대한민국 등록특허공보 등록번호 10-2052348호에는 전열교환기는 실내로부터 공기를 흡기하는 실내흡입부, 실내로 공기를 배기하는 실내배기부, 실외로부터 공기를 흡기하는 실외흡입부, 및 실외로 공기를 배기하는 실외배기부가 구비된 본체케이싱; 상기 실내흡입부 및 상기 실외흡입부로부터 흡기된 공기가 통과하면서,상호 열교환을 할 수 있는 열교환모듈; 상기 실외배기부측으로 공기를 배기할 수 있는 실외측팬부; 상기 실내배기부측으로 공기를 배기할 수 있는 실내측팬부; 및 상기 본체케이싱 내부에서 상기 실내배기부 및 상기 실외배기부 사이에 배치되는 필터카트리지모듈 및 제어모듈을 포함하여 에너지를 절약하고 먼지를 제거하는 공기순환기가 개시되어 있다.In addition, in the Republic of Korea Patent Publication No. 10-2052348, the total heat exchanger has an indoor intake for intake air from the room, an indoor exhaust for exhausting air into the room, an outdoor intake for intake air from the outdoors, and air to the outdoors. Body casing provided with an outdoor exhaust for exhausting; a heat exchange module capable of mutually exchanging heat while passing the air sucked in from the indoor suction unit and the outdoor suction unit; an outdoor fan unit capable of exhausting air toward the outdoor exhaust unit; an indoor fan unit capable of exhausting air toward the indoor exhaust unit; and a filter cartridge module and a control module disposed between the indoor exhaust part and the outdoor exhaust part inside the main casing, to save energy and remove dust.
이러한 선행문헌에 기재된 공기순환기는 배기되는 공기에 포함되는 에너지를 회수하고, 일반 필터를 사용하여 어느 정도 큰 먼지를 제거할 수 있으나, 그 구조상 정밀필터가 설치되어 있지 않아 미세먼지를 제거하기는 어렵다.The air circulator described in these prior documents recovers the energy contained in the exhausted air and can remove a large amount of dust using a general filter, but it is difficult to remove fine dust because a precision filter is not installed in its structure. .
또한 이들 필터를 정밀피터로 교체한다 하더라도, 정밀필터로 작은 미세먼지 입자를 필터링하려면 미세먼지의 크기보다 작은 통과 공으로 형성되는 필터로 필터링을 하여야 하나, 정밀필터는 필터 저항이 커서 에너지가 낭비되고, 미세먼지 자체가 그 입자크기가 작아 필터 깊숙이 박히므로 수시로 필터가 막혀서 필터의 교체로 인한 비용이 많이 소요되는 문제점이 있다.In addition, even if these filters are replaced with precision filters, in order to filter small fine dust particles with a precision filter, it is necessary to filter with a filter formed with a passing ball smaller than the size of fine dust. Since the fine dust itself has a small particle size and is deeply embedded in the filter, there is a problem that the filter is often clogged, and the cost of replacing the filter is high.
또한 공기순환기에 적체되는 바이러스가 부착된 먼지가 시간이 경과하면서 공기순환기에 늘어붙어서 바이러스 및 세균의 전파 매개체가 되는 문제점이 있다.In addition, there is a problem in that the dust attached to the virus accumulated in the air circulator becomes a propagation medium of viruses and bacteria as time passes.

스페이서(414)은 양극교환판(411)과 음극교환판(412) 사이에 절연이 유지되도록 프라스틱과 같은 절연재질로 형성되되 폭이 좁은 띠 형태로 되어 있으며, 양 측단부에 스페이서 결합구멍(415)이 형성되어 있고, 열교환판에도 대응되는 위치에도 열교환판 결합구멍(416)이 형성되어, 결합구멍에 진동파이프(417)가 끼워져 결합되는 것이 바랍직하다. The spacer 414 is formed of an insulating material such as plastic to maintain insulation between the positive electrode exchange plate 411 and the negative electrode exchange plate 412 and has a narrow band shape, and spacer coupling holes 415 are formed at both side ends. ) is formed, and a heat exchange plate coupling hole 416 is also formed at a position corresponding to the heat exchange plate, and it is preferable that the vibration pipe 417 is inserted into the coupling hole to be coupled.
또한 상기 열교환판에 형성된 굴곡과 같은 형상의 굴곡을 두어 열교환판의 결합이 용이하게 하는 것이 바람직하다.In addition, it is preferable to provide a curve having the same shape as the curve formed on the heat exchange plate to facilitate coupling of the heat exchange plate.

도3에 도시된 바와 같이 외부공기휀(620)과 외부공기휀(610)의 토출부 케이싱에는 외부공기휀 역세척 개폐댐퍼(621)과 내부공기휀 역세척 개폐댐퍼(611)가 형성되는 것이 바람직하다. 이러한 역세척 개폐댐퍼는 역세척시에 개방되어 공기의 흐름을 바꾸어 역세척이 되도록 한다.As shown in FIG. 3, the external air fan backwash open/close damper 621 and the internal air fan backwash open/close damper 611 are formed on the discharge part casing of the external air fan 620 and the external air fan 610. desirable. This backwash opening/closing damper is opened during backwashing to change the flow of air to enable backwashing.
이렇게 외부공기휀(620)과 외부공기휀(610)의 토출부 케이싱에는 외부공기휀 역세척 개폐댐퍼(621)과 내부공기휀 역세척 개폐댐퍼(611)가 형성되고 역세척시에 개방되어 공기의 흐름을 바꾸어 다른 장치의 부가없이 전열교환기 케이싱내에서 역세척을 행하므로 좁은 천정 속에 설치할 수 있다.In this way, an external air fan backwash open/close damper 621 and an internal air fan backwash open/close damper 611 are formed on the discharge part casing of the external air fan 620 and the external air fan 610, and are opened during backwashing to allow air It can be installed in a narrow ceiling because backwashing is performed in the total heat exchanger casing without the addition of other devices by changing the flow.
본 공기순환기에 역회전이 운전이 가능한 프로펠라 휀 등을 채택시에는 외부공기휀(620)과 내부공기휀(610)은 역회전이 가능하도록 3상의 전원이 연결되고, 제어모듈(700)의 제어에 의해 연결된 상이 바뀌어 외부공기휀(620)과 내부공기휀(610)이 역회전하여 공기의 흐름이 반대가 되도록 하여 역세척할 수도 있다. 이때는 역세척 구성이 단순해지는 장점이 있는 반면에 프로펠라 휀 등의 구조상 공기순환기가 커지는 단점이 있다.When a propeller fan that can operate in reverse rotation is adopted in this air circulator, the external air fan 620 and the internal air fan 610 are connected to three-phase power so that the reverse rotation is possible, and the control module 700 is controlled. The phase connected by the is changed so that the external air fan 620 and the internal air fan 610 are reversely rotated so that the flow of air is reversed, so that the backwash can be performed. In this case, there is an advantage in that the backwashing configuration is simplified, but there is a disadvantage in that the air circulator becomes large due to the structure of the propeller fan.
아래에서는 상기와 같이 구성된 공기순환기(10)의 작용 효과를 설명한다.Hereinafter, the effect of the air circulator 10 configured as described above will be described.
전열교환모듈(400)은 전열교환소자(410)가 직교를 이루고 교대로 배열됨으로서 일측방향으로 배열된 전열교환소자(410)에 배기되는 내부공기가 지날 수 있도록 하고 타측방향으로 배열된 전열교환소자(410)에 급기되는 외부공기가 지날 수 있도록 하여 실내의 공기가 실외로 배출되는 실내 공기 경로와 실외의 공기가 실내로 유입되는 실외 공기 경로가 서로 교차되어 열교환판을 통한 열교환이 원활하게 이루어진다.The total heat exchange module 400 allows the internal air exhausted to the total heat exchange elements 410 arranged in one direction to pass through as the total heat exchange elements 410 are orthogonal and are alternately arranged, and the total heat exchange elements arranged in the other direction. By allowing the external air supplied to the 410 to pass through, the indoor air path through which the indoor air is discharged to the outdoors and the outdoor air path through which the outdoor air flows into the room cross each other, so that heat exchange through the heat exchanger plate is performed smoothly.
일반적으로 미세먼지는 이온 상태로 존재하고, 양전하(+)나 음전하(-)로 극성을 갖고 있다.In general, fine dust exists in an ionic state and has a polarity with a positive (+) or negative (-) charge.
이러한 이온 상태의 미세먼지를 서로 다른 전위차를 가지는 인접한 금속판이 형성하는 전기장 예를 들면 구리판과 알루미늄판이 서로 인접해 있으면 이중 구리의 수소전극에 대한 전극전위 +0.338V 알루미늄의 수소전극에 대한 전극전위는 1.662V로 구리판은 음극의 성질을 띠게 되고 알루미늄 판은 양극의 성질을 띠게 되어 금속판 전극 사이에는 전기력이 작용하는 공간인 전기장이 형성된다.For example, if a copper plate and an aluminum plate are adjacent to each other, the electric field formed by adjacent metal plates with different potential differences for such ionic fine dust is double copper electrode potential to the hydrogen electrode + 0.338 V At 1.662V, the copper plate takes on the properties of a cathode and the aluminum plate takes on the properties of an anode.
이러한 전기장 내에 양전하(+)나 음전하(-)로 극성을 갖는 미세먼지가 통과되면, 전극과 미세먼지 입자의 전하가 동종일 경우에는 상호반발력이 작용하고, 이종일 경우에는 상호인력이 작용하므로, 미세먼지가 비교적 가벼울 때는 전기력에 의해 대전체에 끌어당겨지므로 극성을 가진 미세먼지가 반대되는 극성을 가진 금속판 전극인 열교환판에 반복적으로 부착되게 되어 그 입자가 결합되어 좀더 큰 결합입자를 형성하고, 결합입자가 어느 정도 커지게 되면 열교환판에서 탈락하여 공기와 함께 유동하게 된다When fine dust having a polarity with a positive charge (+) or a negative charge (-) passes in this electric field, if the charges of the electrode and the fine dust particles are the same, a mutual repulsive force acts. When the dust is relatively light, it is attracted to the charged object by electric force, so fine dust with polarity is repeatedly attached to the heat exchange plate, which is the electrode of the metal plate with the opposite polarity, and the particles are combined to form larger bonded particles. When the particles grow to a certain extent, they fall off the heat exchange plate and flow with the air.
이렇게 열교환판의 구성은 공기와 함께 유동하는 미세먼지 입자간의 결합을 통해 미세먼지 입자의 크기를 최대화시켜 미세먼지의 제거효율을 높이고, 필터의 수명을 연장시켜 필터의 교체로 인한 비용을 절약할 수 있다.In this way, the configuration of the heat exchange plate maximizes the size of fine dust particles through bonding between the fine dust particles flowing with the air, thereby increasing the fine dust removal efficiency, and extending the life of the filter, thereby reducing the cost of replacing the filter. have.
내부공기휀(610)이 구동되면 내부 공기는 실내 공기 경로(710)를 따라 실내흡입구(210)를 통해 실내흡입존(110)으로 유입되고, 실내프리필터(511)과 전열교환모듈(400)를 순서대로 통과하여 실외배출존(140)으로 유입된 후 실외배출구(240)를 통해 실외로 배출된다.When the internal air fan 610 is driven, the internal air flows into the indoor suction zone 110 through the indoor intake 210 along the indoor air path 710, and the indoor pre-filter 511 and the total heat exchange module 400. After passing through in order to be introduced into the outdoor discharge zone 140, it is discharged to the outdoors through the outdoor outlet 240.
그리고, 외부 공기는, 외부공기휀(620)이 구동되면 실외 공기 경로(720)를 따라 실외흡입구(230)를 통해 실외흡입존(130)으로 유입되고, 실외프리필터(531)와 전열교환소자(400) 및 정밀필터(522)와 정전기필터 (526)를 통과한 후 실내배출구(220)를 통해 실내로 배출된다.And, when the external air fan 620 is driven, the external air flows into the outdoor suction zone 130 through the outdoor intake 230 along the outdoor air path 720 along the outdoor air path 720, and the outdoor pre-filter 531 and the total heat exchange element After passing through 400 and the precision filter 522 and the electrostatic filter 526 , it is discharged into the room through the indoor outlet 220 .
이때, 실내 공기 경로(710)와 실외 공기 경로(720)가 전열교환소자(400)에서 교차되면서 내부 공기와 외부 공기가 서로 열을 교환하게 된다. 이처럼, 공기가 서로 교차하도록 함으로써, 겨울철에는 실내의 열이 실외로 배출되는 것을 방지하고, 여름철에는 실외의 열이 실내로 들어오는 것을 방지할 수 있어 환기 과정에서 발생되는 에너지 손실을 최소화 할 수 있다.At this time, as the indoor air path 710 and the outdoor air path 720 intersect at the total heat exchange element 400 , the internal air and the external air exchange heat with each other. As such, by allowing the air to cross each other, it is possible to prevent indoor heat from being discharged to the outdoors in winter and to prevent outdoor heat from entering the room in summer, thereby minimizing energy loss generated in the ventilation process.
또한 유동 과정에서 내부 공기와 외부 공기에 포함되어 있는 먼지는 프리필터에서 큰 입자는 걸러지고, 양전하(+)나 음전하(-)로 극성을 갖고 있는 .미세한 입자는 반대되는 극성을 가진 금속판 전극인 열교환판에 부착되거나 좀 더 큰 입자를 형성하게 되어 정밀 필터(522)에 의해 걸러진다..In the flow process, large particles are filtered out by the pre-filter for dust contained in the internal and external air, and the fine particles, which have polarities with positive (+) or negative (-) charges, are metal plate electrodes with opposite polarities. It is attached to the heat exchange plate or forms larger particles and is filtered by the precision filter 522.
이러한 운전을 하게 되면 먼지가 열교환판, 정밀필터(522) 등 장치 내에 쌓이게 되고, 먼지가 시간이 지나면서 응고되어 열교환을 방해하게 되므로, 본 발명에서는 환풍기의 일정시간 가동 후 공기의 흐름을 반대로 하는 역세척을 실시하게 한다.When this operation is performed, dust accumulates in the device such as the heat exchange plate and the precision filter 522, and the dust solidifies over time and interferes with heat exchange. Do backwashing.
본 발명에서는 외부공기 계통의 역세척을 위하여 실내배출개폐댐퍼(227)와 실외배출개폐댐퍼(247)를 닫고, 실내배출존(120)과 실외배출존(140) 사이의 격벽에 설치되어 구동기에 의하여 개폐되는 역세개폐댐퍼(257)와 내부공기휀 역세척 개폐댐퍼(611)를 개방한 상태에서, 내부공기휀(610)을 가동한다.In the present invention, the indoor exhaust opening/closing damper 227 and the outdoor exhaust opening/closing damper 247 are closed for backwashing of the outside air system, and installed on the partition wall between the indoor exhaust zone 120 and the outdoor exhaust zone 140 to the actuator. In the state in which the backwash opening/closing damper 257 and the internal air fan backwash opening/closing damper 611, which are opened and closed, are opened, the internal air fan 610 is operated.
내부공기휀(610)이 가동되면, 내부공기휀(610)에서 토출되는 공기는, 실외배출존(140), 역세개폐댐퍼(257), 실내배출존(120), 전열교환모듈(400)의 경로로 토출되며 역세척을 실시한다.When the internal air fan 610 is operated, the air discharged from the internal air fan 610 may It is discharged through the path and backwashed.
또한 내부공기계통의 역세척을 위하여 실내배출개폐댐퍼(227)와 실외배출개폐댐퍼(247)를 닫고, 역세개폐댐퍼(257)와 외부공기휀 역세척 개폐댐퍼(621)를 개방한 상태에서, 외부공기휀(620)을 가동한다.In addition, for backwashing the internal air system, the indoor exhaust opening/closing damper 227 and the outdoor exhaust opening/closing damper 247 are closed, and the backwashing opening/closing damper 257 and the external air fan backwashing opening/closing damper 621 are opened. The external air fan 620 is operated.
외부공기휀(620)이 가동되면, 외부공기휀(620)에서 토출되는 공기는 실내배출존(120), 역세개폐댐퍼(257), 실외배출존(140), 전열교환모듈(400)의 경로로 토출되며 역세척을 실시한다.When the external air fan 620 is operated, the air discharged from the external air fan 620 is the indoor exhaust zone 120, the backwash opening/closing damper 257, the outdoor exhaust zone 140, and the path of the total heat exchange module 400 is discharged and backwashed.
이렇게 역세척을 실시하면 별도의 역세척을 위한 장치를 두지않아도 역세척이 가능하고, 에너지가 많이 소모되는 정상 운전시에 외부공기휀(620)과 내부공기휀(610)의 토출경로에 댐퍼를 두거나 챕버를 통한 급격한 공기통로의 확대 축소 등으로 인한 효율 감소로 인한 에너지 낭비가 되지 않는 효과가 있다.When backwashing is performed in this way, backwashing is possible without a separate device for backwashing, and a damper is installed in the discharge path of the external air fan 620 and the internal air fan 610 during normal operation, which consumes a lot of energy. There is an effect that energy is not wasted due to a decrease in efficiency due to the rapid expansion or reduction of the air passage through the chap.
이렇게 역세척이 되어 탈락된 먼지는 실내프리필터(511)의 하단에 설치되는 실내먼지수집부(522)와 실외프리필터(535)의 하단에 설치되는 실외먼지수집부(532)에 수집되어 제거된다.The dust removed by backwashing is collected and removed by the indoor dust collecting unit 522 installed at the lower end of the indoor pre-filter 511 and the outdoor dust collecting unit 532 installed at the lower end of the outdoor pre-filter 535 . do.
또한 공기순환기에 역회전이 가능한 프로펠라 휀 등을 채택시에는 외부공기휀(620)과 내부공기휀(610) 역회전하여 공기의 흐름이 반대가 되도록 하여 역세척할 수도 있다. 이렇게 하면 공기의 흐름에 추가로 장치를 설치하지 않아도 되므로 추가 장치에 의한 저항으로 인한 에너지 낭비가 적게 된다.In addition, when a propeller fan capable of reverse rotation is employed in the air circulator, the external air fan 620 and the internal air fan 610 are reversely rotated so that the flow of air is reversed, thereby performing backwashing. This eliminates the need for additional devices to be installed in the airflow, resulting in less energy wastage due to resistance by the additional devices.
