본 발명은 냉각/제습열 회수기술을 이용한 공조기에 관한 것으로, 좀 더 상세하게는 여름철에 실내 온도와 습도를 적정하게 유지시키기 위해 실내공기 또는 실외공기를 흡입하여 적절히 냉각/제습시킬 때에 필요한 에너지를 회수하여 재사용함으로써 에너지를 절약할 수 있는 냉각/제습열 회수기술을 이용한 공조기에 관한 것이다.The present invention relates to an air conditioner using a cooling / dehumidifying heat recovery technology, and more particularly, in order to properly maintain indoor temperature and humidity in summer, indoor air or outdoor air is sucked in to properly cool / dehumidify energy. It relates to an air conditioner using a cooling / dehumidification heat recovery technology that can save energy by recovering and reusing.
공조기(AHU, Air Handling Unit)는 건물의 기계실이나 공조실 등에 설치되어 공기를 냉각시키거나 가열하여 닥트를 통해 각 실내로 공급하는 장치로서, 이를 위해 공조기에는 일반적으로 실내에 공급되는 공기를 쾌적한 수준의 온도와 습도로 유지하기 위한 냉각, 제습 및 가열, 가습하는 구성을 포함하며, 여름철에는 냉각장치에 의해 공기를 냉각시켜 실내에 공급하고, 겨울에는 가열장치를 통해 공기를 가열하여 실내에 공급하게 되며, 특히 여름철에 공기 중에 과다한 양의 습기가 포함된 경우 공기로부터 습기를 제거한 다음 실내에 공급하는데 이때 먼저 냉각장치에 의해 공기를 제습에 필요한 온도까지 낮은 온도로 냉각시켜 실내에 공급한다.An air handling unit (AHU) is installed in a machine room or air conditioning room of a building to cool or heat air and supply it to each room through a duct. For this purpose, an air conditioner generally provides a comfortable level of air supplied to a room. It includes cooling, dehumidification, heating, and humidification to maintain temperature and humidity.In summer, air is cooled and supplied to the room by a cooling device, and in winter, air is heated and supplied to the room by a heating device. In particular, when the summer contains an excessive amount of moisture, the moisture is removed from the air and then supplied to the room. At this time, the air is cooled to a temperature necessary for dehumidification by a cooling device and then supplied to the room.
이러한 기능을 가지는 공조기는 일반적으로 도 1에 도시된 바와 같은 구조를 가지는데, 공조기 내로 유입된 공기는 송풍기(101)에 의해 하류측으로 송풍되고, 이 송풍된 공기는 필터를 통해 먼지 등이 걸러진 다음, 냉각코일(120) 및/또는 히팅코일을 거치면서 냉각되거나 가열된 후, 필요에 따라 가습장치에 의해 가습된 다음 송풍기(102)를 통해 다시 실내로 공급되며, 이때 코일(120)의 하부에는 드레인부(121)가 설치되어 있어 냉각코일(120)로부터 생성되는 응축수가 이를 통해 공조기의 외부로 배출된다.An air conditioner having such a function generally has a structure as shown in FIG. 1, wherein the air introduced into the air conditioner is blown downstream by the blower 101, and the blown air is filtered through dust and then filtered. After being cooled or heated while passing through the cooling coil 120 and / or the heating coil, it is humidified by a humidifier as necessary and then supplied back to the room through the blower 102, wherein the lower portion of the coil 120 Since the drain portion 121 is installed, the condensed water generated from the cooling coil 120 is discharged to the outside of the air conditioner.
이러한 공조기는 여름철에 공조기 내부로 공급되는 공기 중에 다량의 습기가 포함된 경우 공기 중의 과다한 양의 습기를 제거하기 위해 먼저 공조기 내부에 설치된 냉각코일을 통해 공기를 제습에 필요한 온도까지 낮은 온도로 냉각시켜 공기 중의 습기를 제거한다.If the air conditioner contains a large amount of moisture in the summer, the air conditioner first cools the air to a temperature necessary for dehumidification through a cooling coil installed inside the air conditioner to remove an excessive amount of moisture in the air. Remove moisture from the air.
이때 공기의 온도가 너무 낮기 때문에 다시 가열장치에 의해 공기를 적정 온도로 재가열하여 실내에 공급하여야 하지만 에너지가 추가로 소요되므로 대부분의 공조기에서는 이러한 재가열을 위한 장치가 생략되어 있어서 쾌적한 상태의 공기를 실내에 공급하기 어렵다.At this time, because the temperature of the air is too low, the air must be reheated by the heating device to the proper temperature and supplied to the room. However, since the energy is additionally required, the device for reheating is omitted in most air conditioners, so that the air in a comfortable state is indoors. It is difficult to feed on.
본 출원인은 여름철에 공조기로 제습을 하는 경우 냉각코일을 통해 공기를 제습에 필요한 온도까지 냉각시킨 다음, 다시 가열장치에 의해 공기를 재가열하는데 따른 에너지 손실을 방지하기 위해 에너지 절약형 냉각/재가열 시스템에 관한 발명을 제안하여 특허등록(특허 제0836232호)을 받은 바 있다.Applicant relates to an energy-saving cooling / reheating system for cooling the air to a temperature required for dehumidification through a cooling coil when dehumidifying the air conditioner in summer, and then again to prevent energy loss caused by reheating the air by a heating device. Proposed invention and received a patent registration (Patent No. 0836232).
상기 문헌에 제안된 기술은 도 2에 도시된 바와 같이 에너지 절약형 냉각/재가열 시스템에 공기유입부를 구비하고 이 공기공급부를 통과한 공기가 사각 형상의 판형 열교환기(210)를 통과하도록 한 다음, 냉각코일(220)을 거쳐 그 흐름 방향이 전환(200)된 다음, 재차 판형 열교환기(210)를 통과시킨 후 히팅코일(230)을 거쳐 공기유입부와 평행(병렬)으로 설치된 공기유출부를 따라 실내로 공급되도록 구성된 것으로, 이때 공기는 ①->②->③->④->⑤의 유로를 따라 흐르게 되는데, 이러한 구성에 의해 여름철에 공기를 제습하는 경우 냉각코일에 의해 공기를 제습에 필요한 온도까지 냉각시켜 제습시킨 다음, 이 저온의 공기를 판형 열교환기(210)를 거치도록 함으로써 히팅코일 등에 의해 공기를 재가열하지 않아도 열교환기(210)에 의해 공기가 재가열되므로 냉각 및 제습에 필요한 에너지와 재가열에 따른 에너지를 절약할 수 있다.The technique proposed in this document is provided with an air inlet in the energy-saving cooling / reheating system as shown in FIG. 2 and allows the air passing through the air supply to pass through the square plate heat exchanger 210 and then cooled.

도 3a 및 도 5a는 각각 본 발명에 따른 공조기의 사용예를 보인 구성도로서 이들 도면에 도시된 바와 같이 본 발명의 공조기(10)는 그 내부에 송풍기(20), 열교환기(30), 냉각코일(40), 가습장치(60) 및 송풍기(70)가 공기 흐름 방향을 따라 차례로 위치된다. 그리고 이러한 구조의 공조기(10)에는 상류측으로부터 실내공기 흡입구(11), 실내공기 배출구(12) 및 실외공기 흡입구(13)가 차례로 연결되어 있어 이들로부터 실내외 공기가 유입되고, 이 유입된 공기는 냉각코일(40)을 통해 냉각된 다음 실내로 공급된다. 이때 실내외 공기가 냉각코일(40)으로 유입되기 전에 필터(14)를 통과하도록 함으로서 공기 중의 이물질이나 미세먼지를 제거할 수 있도록 구성될 수 있다.3A and 5A are diagrams showing examples of the use of the air conditioner according to the present invention. As shown in these drawings, the air conditioner 10 of the present invention includes a blower 20, a heat exchanger 30, and cooling therein. The coil 40, the humidifier 60 and the blower 70 are sequentially located along the air flow direction. In addition, the indoor air inlet 11, the indoor air outlet 12, and the outdoor air inlet 13 are sequentially connected to the air conditioner 10 having such a structure, and indoor and outdoor air is introduced therefrom. It is cooled through the cooling coil 40 and then supplied to the room. At this time, by passing through the filter 14 before the indoor and outdoor air flows into the cooling coil 40 may be configured to remove foreign matter or fine dust in the air.
한편, 냉각코일(40)에 냉수배관을 연결하는 대신에 온수배관을 연결하게 되면 이 냉각코일(40)은 동절기에 히팅코일로 사용할 수도 있는데, 따라서 도면 부호 40은 냉각코일 또는 히팅코일을 지칭하는 것으로 사용될 수도 있다.On the other hand, when the hot water pipe is connected to the cooling coil 40 instead of connecting the cold water pipe 40, the cooling coil 40 may be used as a heating coil in the winter, and therefore, reference numeral 40 denotes a cooling coil or a heating coil. May be used.
실내공기 흡입구(11)를 통해 실내로부터 유입된 일부 공기는 실내 환기를 위해 냉각코일(40)을 거치지 않고 실내공기 배출구(12)를 통해 바로 실외로 배출된다.Some air introduced from the room through the indoor air inlet 11 is discharged directly to the outside through the indoor air outlet 12 without passing through the cooling coil 40 for indoor ventilation.
위와 같은 본 발명의 공조기의 구성 중 송풍기(20), 냉각코일(40), 가습장치(60) 및 송풍기(70)가 구비되고, 공조기에 실내공기 흡입구(11), 실내공기 배출구(12) 및 실외공기 흡입구(13)가 연결되는 구성은 종래의 일반적인 공조기의 구성과 동일하며, 다만, 본 발명은 종래의 공조기와 비교하여 공기의 흐름이 다른데, 이는 냉각코일(40)의 전단에 열교환기(30)가 설치되는데 기인한다.In the configuration of the air conditioner of the present invention as described above, a blower 20, a cooling coil 40, a humidifier 60 and a blower 70 is provided, the air conditioner inlet air 11, the indoor air outlet 12 and the air conditioner The outdoor air inlet 13 is connected to the same configuration as the conventional air conditioner, but the present invention is different from the conventional air conditioner air flow, which is the heat exchanger (front end of the cooling coil 40) 30) is installed.
본 발명에 사용되는 열교환기(30)는 도 5b에 도시된 바와 같은 4각 형상의 상, 하부 열교환판(30A, 30B)이 상하 교대로 다수 적층됨으로써 그 사이 공간은 공기가 흐르는 공기통로가 형성되는데, 흡기구(31, 33)를 통해 열교환기에 유입된 공기는 이러한 열교환판 사이에 형성된 상하의 공기통로를 따라 흐른 후 배기구(32, 34)로 통해 배출되고, 이 과정에서 열교환이 일어나도록 한 적층형 판형 열교환기이다.In the heat exchanger 30 used in the present invention, a plurality of upper and lower heat exchange plates 30A and 30B having a quadrangular shape as shown in FIG. 5B are alternately stacked up and down to form an air passage through which air flows. The air flowing into the heat exchanger through the inlets 31 and 33 flows along the upper and lower air passages formed between the heat exchange plates, and then is discharged through the exhaust ports 32 and 34. Heat exchanger.
이러한 열교환기(30)는 도 7에 도시된 바와 같이 상하로 적층되는 판형 열교환기를 사용하는 것으로, 상부 열교환판(30A)의 흡입구(31)로 유입된 공기는 평면상에 다수 돌출 형성된 돌기를 거쳐 배출구(32)로 배출되고, 이후 냉각코일(40)을 거친 공기가 하부 열교환판(30B)의 흡입구(33)를 통해 재유입되어 배출구(34)로 배출되면서 상, 하부 열교환판(30A, 30B) 사이로 통과하는 공기 사이에서 열교환이 일어난다.The heat exchanger 30 uses a plate heat exchanger stacked up and down as shown in FIG. 7, and the air introduced into the suction port 31 of the upper heat exchanger plate 30A passes through a plurality of protrusions formed on a plane. The air is discharged to the outlet 32, and the air passing through the cooling coil 40 is then re-introduced through the inlet 33 of the lower heat exchanger plate 30B and discharged to the outlet 34 so that the upper and lower heat exchanger plates 30A and 30B The heat exchange takes place between the air passing through.
본 발명의 열교환기의 내부를 따라 흐르는 열교환 매체는 상하층 모두 공기로서 그 압력이 그리 크지 않을 뿐만 아니라, 정사각형 또는 직사각형 등으로 그 형상을 필요에 따라 바꿀 필요가 있기 때문에 본 발명의 열교환기는 성형성이 뛰어난 플라스틱으로 제작된 열교환기를 사용하는 것이 바람직하다.Since the heat exchange medium flowing along the inside of the heat exchanger of the present invention does not have a large pressure as air in both the upper and lower layers, it is necessary to change the shape as necessary in square or rectangular shape. It is desirable to use heat exchangers made of this superior plastic.
이러한 구조의 열교환기를 이용한 본 발명의 공조기의 구성을 그 실시예를 통해 설명한다.The configuration of the air conditioner of the present invention using a heat exchanger having such a structure will be described with reference to the embodiment.
<실시예 1><Example 1>
실시예 1은 도 3a에 도시된 바와 같이 실내공기가 냉각코일(40)을 두 번 통과하는 구조로 이루어진 공조기에 관한 것으로서, 냉각코일(40)의 전면의 일부에는 도 3b에서와 같은 구조의 열교환기, 즉 상부 열교환판(30A)의 흡기구(31)와 배기구(32)는 상부 열교환판(30A)의 좌측면과 우측면에 각각 형성되고, 하부 열교환판(30B)의 흡기구(33)와 배기구(34)는 하부 열교환판(30B)의 상면과 하면에 각각 형성되어 교대로 적층되는 열교환기(30)가 설치되고, 상기 열교환기(30)의 전면 하단은 수직구획판(81)에 의해 지지됨으로써 상기 열교환기(30)의 하부는 그 전방면이 수직구획판(81)에 의해 밀폐된 공기통로(10A)가 형성된다. Embodiment 1 relates to an air conditioner having a structure in which indoor air passes through a cooling coil 40 twice as shown in FIG. 3A, wherein a part of the front surface of the cooling coil 40 has a heat exchange structure as shown in FIG. 3B. That is, the inlet port 31 and the exhaust port 32 of the upper heat exchanger plate 30A are formed on the left and right sides of the upper heat exchanger plate 30A, respectively, and the inlet port 33 and the exhaust port of the lower heat exchanger plate 30B ( 34 is provided on the upper and lower surfaces of the lower heat exchanger plate 30B, respectively, and the heat exchanger 30 is alternately stacked, and the lower end of the front surface of the heat exchanger 30 is supported by the vertical partition plate 81. The lower portion of the heat exchanger 30 has an air passage 10A whose front surface is sealed by the vertical partition plate 81.
그리고 상기 냉각코일(40)의 하류측에는 냉각코일(40)과 일정 간격 이격되며 그 상단에 수평구획판(83)이 부착된 수직구획판(82)이 설치되며 이에 의해 냉각코일(40)의 하류측에 또 다른 공기통로(10B)가 형성된다.And the downstream side of the cooling coil 40 is spaced apart from the cooling coil 40 by a predetermined interval and the vertical partition plate 82 is attached to the horizontal partition plate 83 is installed at the upper end by the downstream of the cooling coil 40 Another air passage 10B is formed on the side.
또한 상기 열교환기(30), 냉각코일(40) 및 공기통로(10B)의 상부에는 공기통로(10A)의 하류측과 연결되는 또 다른 공기통로(10C)가 형성된다.In addition, another air passage 10C is formed at an upper portion of the heat exchanger 30, the cooling coil 40, and the air passage 10B and connected to a downstream side of the air passage 10A.
이상과 같은 공조기의 구조에 의해 본 발명은 송풍기(20)에 의해 실내공기가 실내공기 흡입구(11)로부터 흡입된 다음 실내공기 배출구(12)를 통해 일부가 외부로 배출되고, 배출되는 실내공기의 양에 맞춰 실외공기 흡입구(13)를 통해 실외공기가 유입되어 실내공기와 혼합된다.According to the structure of the air conditioner as described above, the indoor air is sucked from the indoor air intake port 11 by the blower 20, and then a part of the indoor air is discharged to the outside through the indoor air discharge port 12. According to the amount, outdoor air is introduced through the outdoor air inlet 13 and mixed with the indoor air.
이후 실내외 공기가 혼합된 혼합공기는 그 내부의 공기통로를 따라 그 하류측에 설치된 열교환기(30)와 냉각코일(40)을 순서대로 통과한 후 공기통로(10B)를 따라 흐르고, 냉각코일(40)을 다시 한 번 통과한 후 공기통로(10A)를 따라 흐르며, 열교환기(30)를 다시 한 번 통과한 후 공기통로(10C)를 따라 하류측으로 흐른다.Then, the mixed air mixed with the indoor and outdoor air passes through the heat exchanger 30 and the cooling coil 40 installed in the downstream side along the air passage therein in order and then flows along the air passage 10B, and the cooling coil ( After passing 40 again, it flows along the air passage 10A, and once again passes through the heat exchanger 30, and then flows downstream along the air passage 10C.
상기와 같이 본 발명은 냉각코일(40)을 2번 통과하면서 혼합공기 중에 포함된 수증기는 응축되어 드레인부(D)를 통해 공조기의 외부로 배출되고, 이에 의해 건조한 상태의 냉각공기가 열교환기(30)로 재유입되면서 타측에서 유입되는 혼합공기와 열교환기(30) 내부에서 층간으로 교차 통과하게 되고, 이 과정에서 혼합공기와 냉각공기 사이에 열교환이 이루어져 혼합공기는 냉각/제습되고 냉각공기는 재가열된다.As described above, the present invention condenses the water vapor contained in the mixed air while passing through the cooling coil 40 twice and is discharged to the outside of the air conditioner through the drain part D, whereby the cooling air in the dry state is a heat exchanger ( Re-introduced into 30), the mixed air flowing from the other side and the heat exchanger 30 cross each other and pass through each other. In this process, heat exchange is performed between the mixed air and the cooling air, and the mixed air is cooled / dehumidified and the cooling air is Reheated.
즉, 본 발명은 상기와 같이 자체 열교환에 의해 혼합공기가 미리 냉각/제습되는 동시에 냉각공기가 재가열되기 때문에 혼합공기를 냉각/제습시키는데 필요한 에너지가 절감되는 동시에 히팅코일에 의해 냉각공기를 재가열할 필요가 없으므로 재가열 에너지가 절감되는 것이다.That is, according to the present invention, since the mixed air is cooled and dehumidified by the self-heat exchange as described above, the cooling air is reheated, and the energy required for cooling / dehumidifying the mixed air is reduced and at the same time, the cooling air is reheated by the heating coil. There is no reheating energy.
한편, 동절기에는 냉각/제습을 위한 열교환기가 필요 없기 때문에 본 발명에서는 공조기(10) 내에 설치되는 열교환기(30)와 수직구획판(81, 82)을 장탈착될 수 있는 구조로 설치하여 동절기에 이들 열교환기(30)와 수직구획판(81, 82)을 공조기(10)로부터 제거할 수 있도록 함으로써 이에 의해 공조기 내로 유입된 실내 또는 실외 공기가 열교환기(30)와 수직구획판(81, 82)에 부딪히지 않고 곧바로 히팅코일을 통과하도록 하여 열효율이 향상되도록 한다.On the other hand, in the winter there is no need for a heat exchanger for cooling / dehumidification in the present invention by installing the heat exchanger 30 and the vertical partition plates 81, 82 installed in the air conditioner 10 in a structure that can be removable The heat exchanger 30 and the vertical partition plates 81 and 82 can be removed from the air conditioner 10, whereby indoor or outdoor air introduced into the air conditioner is transferred to the heat exchanger 30 and the vertical partition plates 81 and 82. Heat resistance is improved by passing heating coil directly without hitting).
상기와 같은 이유로 동절기에 공조기로부터 열교환기가 제거되고 나면 공조기의 상부쪽에 형성된 공기유로(10C)를 통해 일부의 공기가 히팅코일(40)을 거치지 않고 바이패스(bypass)되어 흐를 수 있기 때문에 이를 방지하기 위해 도 4에 도시된 바와 같이 수평구획판(84)으로 이 공기통로(10C)를 막아 모든 공기가 히팅코일(40)을 통과하여 흐르도록 하는 것이 바람직하다.For the same reason, after the heat exchanger is removed from the air conditioner in winter, some air may be bypassed through the heating coil 40 through the air flow path 10C formed at the upper side of the air conditioner, thereby preventing the flow. 4, the air passage 10C is blocked by the horizontal partition plate 84 so that all the air flows through the heating coil 40. As shown in FIG.
