도 2는 본 발명의 바람직한 실시 예에 따른 하이브리드 열회수식 외기공조장치의 구성도를 도시하고 있다. 도 2를 참조하면, 본 발명의 바람직한 실시 예에 따른 외기공조장치(100)는 필터(110)와, 히터(120)와, 제1 순환코일(130)과, 제2 순환코일(141)을 포함하는 에어와셔(140)와, 리히팅 코일(150)이 외기의 도입측으로부터 순차적으로 배치된 것으로 구성되며, 가장 말단에는 외기의 도입 및 처리된 외기를 클린룸(200)으로 공급하기 위한 송풍기(160)가 구비되어 있다.2 is a block diagram of a hybrid heat recovery type outdoor air conditioner according to a preferred embodiment of the present invention. Referring to FIG. 2, the outdoor air conditioner 100 according to a preferred embodiment of the present invention includes a filter 110, a heater 120, a first circulation coil 130, and a second circulation coil 141. The air washer 140 and the heating coil 150, which are included, are configured to be sequentially disposed from the inlet side of the outside air, and the blower for supplying the outside air introduced and processed at the outermost end to the clean room 200 160 is provided.

통상적으로 클린룸(200)으로부터 배출되는 공기의 85%는 드라이코일(201)을 거쳐 냉각된 후 클린룸(200)의 내부로 다시 투입되고, 나머지 15%만이 외부로 배출된다. 본 발명은 재순환되는 85% 공기의 열을 회수하는 반환냉수를 제2 순환코일(141) 및 리히팅 코일(150)로 공급하고, 외부로 배출되는 15% 공기의 열을 회수한 물을 제1 순환코일(130)로 공급하여 도입외기의 가열 또는 냉각에 사용하게 함으로써, 클린룸(200)의 내부에서 발생된 후 버려지는 대부분의 열을 최대한 활용하여 외기공조장치(100)의 부하를 감소시키도록 한 것으로, 이하 각각의 구성요소에 대하여 구체적으로 설명한다.Typically, 85% of the air discharged from the clean room 200 is cooled through the dry coil 201 and then re-introduced into the clean room 200, and only the remaining 15% is discharged to the outside. The present invention supplies the return cold water for recovering the heat of 85% air to be recycled to the second circulation coil 141 and the heating coil 150, and recovers the heat of 15% air discharged to the outside for the first water. By supplying the circulating coil 130 to be used for heating or cooling the introduced outside air, the load of the outside air conditioning apparatus 100 is reduced by making the most of the heat generated after being generated inside the clean room 200. Each component will be described in detail below.

상기 필터(110)는 외기의 도입측에 배치되어 외기중에 포함된 비교적 큰 입자의 이물질을 제거하게 되며, 외기중에 포함된 가스 상의 오염물질을 여과하기 위하여 케미컬필터가 사용될 수도 있다.The filter 110 is disposed on the introduction side of the outside air to remove foreign particles of relatively large particles contained in the outside air, and a chemical filter may be used to filter the gaseous contaminants contained in the outside air.

상기 히터(120)는 겨울철과 같이 대기의 온도가 낮을 경우, 관리자에 의해 선택적으로 작동하여 도입외기를 예열하는 사용되며, 여름철과 같이 대기의 온도가 높을 경우에는 사용되지 아니한다. 이와 같은 히터(120)의 대신하여 가열코일이 설치될 수도 있다. 물론 여름철과 같이 대기 온도가 높을 경우, 냉각기(220)로부터 공급되는 냉각수를 이용하여 도입외기의 온도를 낮추는 미도시된 냉각코일이 구비될 수 있다.The heater 120 is used to preheat the introduced outside air by selectively operating by the manager when the temperature of the atmosphere is low, such as winter, and is not used when the temperature of the atmosphere is high, such as summer. Instead of the heater 120, a heating coil may be installed. Of course, when the air temperature is high, such as summer, a cooling coil not shown to lower the temperature of the introduced outdoor air by using the cooling water supplied from the cooler 220 may be provided.

상기 제1 순환코일(130)은 클린룸(200)으로부터 배출되는 배기의 열을 회수한 물을 공급받아 도입외기를 예열 또는 예냉하는 것으로, 클린룸(200)으로부터 배 출되는 배기의 여과를 위해 세정집진기(210)에서 사용되어 배기의 열을 회수한 물과 열교환을 통해 승온된 물을 공급받도록 구성된다. 이처럼 세정집진기(210) 측의 물과 제1 순환코일(130) 측의 물의 열교환을 위하여 별도의 열교환기(230)가 사용된다.The first circulation coil 130 receives preheated or precooled inlet air by receiving water from which the heat of the exhaust discharged from the clean room 200 is recovered, and for filtering the exhaust discharged from the clean room 200. Used to clean the dust collector 210 is configured to receive the water heated by heat exchange with the water recovered the heat of the exhaust. In this way, a separate heat exchanger 230 is used for heat exchange between the water of the cleaning dust collector 210 and the water of the first circulation coil 130.

상기 제2 순환코일(141)은 도입외기 중의 미세먼지와 수용성 화학기체를 제거하기 위한 물을 분사하는 노즐(142)들과 함께 설치되어 에어와셔(140)를 구성하게 되며, 클린룸(200)의 냉방에 사용된 후, 냉각기(220)로 반환되는 반환냉수를 공급받도록 구성된다.The second circulation coil 141 is installed together with the nozzles 142 for injecting water for removing fine dust and water-soluble chemical gas in the introduced outside air to form an air washer 140, and the clean room 200. After being used for cooling of the, it is configured to receive the return cold water returned to the cooler 220.

보다 구체적으로 상기 반환냉수는 클린룸(200)을 순환하는 85%의 순환공기 냉각을 위하여 별도의 냉각기(220)로부터 약 7℃의 상태로 드라이코일(201)(dry coil)로 공급되어 순환공기의 냉각에 사용된 후, 약 18℃로 승온된 상태로 냉각기(220)로 복귀하는 물을 의미하며, 이처럼 18℃로 승온되어 냉각기(220)로 복귀하는 반환냉수를 제2 순환코일(141)에 공급함으로써, 겨울철에는 도입외기를 가열하게 되고, 이와 반대로 여름철에서는 도입외기를 냉각하게 된다.More specifically, the returned cold water is supplied to the dry coil 201 (dry coil) in a state of about 7 ° C. from a separate cooler 220 for cooling 85% of the circulating air circulating in the clean room 200. After being used for cooling, it means water returning to the cooler 220 in a state of being heated to about 18 ° C, the second return coil 141 to return the cold water is returned to the cooler 220 is raised to 18 ° C as described above By supplying to the air, the introduced outdoor air is heated in winter, and conversely, the introduced outdoor air is cooled in summer.

한편 제2 순환코일(141)로 공급되는 반환냉수는 도입외기와의 열교환을 통해 도입외기를 가열 또는 냉각한 후, 냉각기(220)로 반환된다.Meanwhile, the returned cold water supplied to the second circulation coil 141 is returned to the cooler 220 after heating or cooling the introduced outdoor air through heat exchange with the introduced outdoor air.

상기 리히팅 코일(150)은 제2 순환코일(141)과 마찬가지로 반환냉수를 공급받도록 구성되어 클린룸(200)으로 외기를 투입하기 전, 도입외기를 최종적으로 가열하도록 설치된다.Like the second circulation coil 141, the reheating coil 150 is configured to receive return cold water and is installed to finally heat the introduced outside air before introducing the outside air into the clean room 200.

한편, 냉각기(220)로 반환된 냉각수의 응축에 사용된 후, 냉각탑(240)으로 반환되는 약 30℃의 냉각수를 히터(120)와 제2 순환코일(141) 및 리히팅 코일(150)로 추가적으로 공급하도록 함으로써, 반환냉수만을 이용하여 도입외기의 충분한 가열이 어려울 경우 냉각탑(240)으로 반환되는 고온의 냉각수를 추가적으로 이용함으로써 외기공조장치의 부하를 감소시킬 수 있게 된다.On the other hand, after being used for the condensation of the cooling water returned to the cooler 220, the cooling water of about 30 ℃ returned to the cooling tower 240 to the heater 120, the second circulation coil 141 and the heating coil 150. By additionally supplying, it is possible to reduce the load of the outdoor air conditioner by additionally using a high-temperature cooling water returned to the cooling tower 240 when it is difficult to sufficiently heat the introduced outdoor air using only the return cold water.

상기와 같이 냉각탑(240)으로 반환되는 고온의 냉각수를 히터(120)와 제2 순환코일(141) 및 리히팅 코일(150)로 공급함에 있어, 반환냉수와 함께 공급되도록 구성될 수도 있으며, 반환냉수의 공급은 차단한 상태로 냉각탑(240) 측의 고온의 냉각수만이 공급되도록 할 수도 있다.In supplying the high temperature cooling water returned to the cooling tower 240 to the heater 120, the second circulation coil 141, and the heating coil 150 as described above, it may be configured to be supplied together with the return cooling water, Cold water may be supplied so that only the high temperature cooling water on the cooling tower 240 side is blocked.

상기와 같이 구성된 본 발명의 외기공조장치(100)는 송풍기(160)의 작동에 의해 외기를 도입하게 되며, 이처럼 도입되는 외기는 필터(110)를 거쳐 1차 여과과정을 거친 뒤, 히터(120) 및 제1 순환코일(130)을 거쳐 예열이나 예냉과정을 거치게 된다. 물론 여름철과 같이 도입외기의 온도가 높을 경우, 히터(120)를 사용하지 않을 수도 있다.The outside air conditioner 100 of the present invention configured as described above is introduced to the outside air by the operation of the blower 160, the outside air is introduced through the filter 110 after the first filtration process, the heater 120 ) And the first circulation coil 130 undergoes a preheating or precooling process. Of course, when the temperature of the introduced outdoor air is high, such as summer, the heater 120 may not be used.

상기와 같이 제1 순환코일(130)을 거친 도입외기는 제2 순환코일(141)과 노즐(142)로 이루어지는 에어와셔(140)를 통과함으로써 2차 여과과정을 거치는 것과 함께 온도와 습도가 1차적으로 조정된다.As described above, the introduced outside air passing through the first circulation coil 130 passes through the air washer 140 formed of the second circulation coil 141 and the nozzle 142 to undergo a second filtration process and has a temperature and humidity of 1. Are adjusted differentially.
