본 고안은 일반 공업용 공조 및 산업용 공조로 이용되는 두대의 공기대 액체 열교환기를 폐회로 형성시켜 겨울철 또는 여름철에 배기되는 공기에서 열을 수수하고, 급기되는 공기에서 열을 빼앗거나 전달케한 열회수 시스템에 관한 것이다.The present invention relates to a heat recovery system in which two air-to-liquid heat exchangers used for general industrial air conditioning and industrial air conditioning are formed in a closed loop to receive heat from the air exhausted in winter or summer, and to take heat away from the supplied air or to transfer it. will be.
일반적인 열회수 장치에 있어서는 공기를 매체로 하는 히트 파이프(Heat Pipe)방식과 같이 공급 공기가 간격이 밀접하게 적층된 알루미늄 박판 사이로 통과 되므로서 직접 공기대 열교환 되어 공급공기와 배기공기의 온도차로 인한 공급공기를 가열, 냉각하는 방식과 밀폐된 튜브내의 액체를 이용하되 증발과 액화를 계속반복시킨 그 액체가 증발되는 잠열에 의해 실내에 공급하는 공기를 가열 내지 냉각하는 방식이 있다.In the general heat recovery system, as in the heat pipe method using air as a medium, the supply air is passed between the aluminum thin plates that are closely spaced and the heat is directly exchanged to the air to supply heat due to the temperature difference between the supply air and the exhaust air. Heating and cooling, and a method of heating or cooling the air supplied to the room by the latent heat from which the liquid is evaporated by using the liquid in the sealed tube and repeatedly evaporating and liquefying.
그러나 이들이 갖는 문제점은 밀폐된 튜브내의 액체를 증발키 위해 별도의 가열기가 마련되어야 하고, 또 증발되는 기체를 액화시키기 위한 보조장치 내지 압축장치가 반드시 설치되어야 하므로, 이에 관련된 코스트가 매우 높게 책정될뿐아니라, 이를 보안하기 위한 부대시설과 설치 면적이 대한 제한성을 갖는 문제가 있는 것이다.However, their problem is that a separate heater must be provided to evaporate the liquid in the sealed tube, and an auxiliary device or a compression device for liquefying the vaporized gas must be installed. Rather, there is a problem in that there are limitations on the facilities and the installation area to secure this.
또한 열원 또는 냉원체로 부터 계속 공급되는 급기온도가 과열 내지 과냉될때에도 안전장치가 되어 있지 않아 이에 사용자에게 위험 내지 불안감을 조성하게 되는 폐단이 있었던 것이다.In addition, even when the air supply temperature continuously supplied from a heat source or a cold source is not a safety device even when it is overheated or undercooled, there is a closed point that creates a risk or anxiety for the user.
따라서 본 고안은 종래의 제반적인 결함 및 문제를 해결하기 위해, 공업용 공조에 이용되는 2대의 열교환기를 배기측과 급기측에 설치하되 상호간에 폐회로가 형성된 배관내의 열전달 매체를 계속 순환시키면서 유량을 제어하고, 과열, 과냉에 따른 안전장치가 부여된 열회수 시스템을 보다 저렴한 가격으로 제공코져 하며, 배기되는 열을 회수하여 급기측 부하를 대폭 축소 시키므로서 에너지가 절약됨과 아울러 효율을 향상시키는데 그 목적이 있는 것으로 안출된바 이를 첨부된 도면과 관련하여 보다 상세히 설명하면 더욱 명백해질 것이다.Therefore, in order to solve the conventional defects and problems, the present invention is to install the two heat exchangers used in the industrial air conditioning on the exhaust side and the air supply side, while controlling the flow rate while continuing to circulate the heat transfer medium in the pipe with the closed loop between each other It is intended to provide a heat recovery system that is provided with safety devices for overheating and overcooling at a lower price, and to save energy and improve efficiency by greatly reducing the load on the air supply side by recovering heat exhausted. It will be more apparent if the invention is described in more detail with reference to the accompanying drawings.
급기되는 공기가 송풍기(4)에 의해 가속 진행토록 한 급기측 덕트(1)내에 설정온도 상승 내지 하강때 3방변밸브를 조절케 하는 온도 감지기(13)와, 과열 내지 과냉을 방지하기 위해 순환펌프를 정지케하는 과열, 냉온도 감지기(14) 및 급기되는 공기에서 열을 빼앗거나 전달하는 열교환기(5)를 각각 내장시키고, 배출되는 공기를 다른 송풍기(4')에 의해 가속배기 되도록한 배기측 덕트(2)내에 급기측 열교환기(5)와 동일한 열교환기(6)를 내장한다.A temperature sensor 13 for adjusting the three-way valve when the set temperature rises or falls in the air supply side duct 1 in which the air to be supplied is accelerated by the blower 4, and a circulation pump to prevent overheating or overcooling. And a heat exchanger (5) to take away or transfer heat from the supplied air, and to exhaust the air to be accelerated and exhausted by another blower (4 '). The same heat exchanger 6 as the air supply side heat exchanger 5 is built in the side duct 2.
그런다음, 먼저 급기되는 공기가 영하일때 수용액의 동결로 인한 열교환기(5)의 동파를 막기 위해, 에틸렌글리콜 수용액을 열전달 매체로 배관(15)내에 주입하고 액체의 온도 변화에 따른 체적 팽창을 감당할 수 있도록 팽창탱크(3)가 부여된다.Then, in order to prevent freezing of the heat exchanger 5 due to freezing of the aqueous solution when the air to be supplied is below freezing, an aqueous solution of ethylene glycol is injected into the pipe 15 through a heat transfer medium and subjected to volume expansion according to the temperature change of the liquid. Expansion tank 3 is provided.
이와 같은 상태의 급기측 열교환기(5)와, 배기측 열교환기(6)와의 사이에는 물 또는 에틸렌글리콜 수용액이 주입된 파이프(15)로 폐회로를 형성시키되 과열, 과냉 방지 온도 감지기(14)가 연결되어 열교환 매체인 액체를 유동시키는 순환펌프(7)와 액체의 온도 변화에 따라 체적 팽창을 감당케한 팽창탱크(3) 및 온도 감지기(13)로 비례제어 되는 3방변 밸브(8)를 급기측 열교환기(5), 배기측 열교환기(6), 순환펌프(7)측 유로를 조절하도록 연결시킨다음, 급기 송풍기(4)와 배기 송풍기(4') 및 순환펌프(7)에 별도의 전원이 인가되도록 연결시켜 구성된 것으로 미설명 부호(9, -12)는 슬라이드 밸브이다.A closed circuit is formed between the air supply side heat exchanger 5 and the exhaust side heat exchanger 6 in this state with a pipe 15 into which water or an ethylene glycol aqueous solution is injected. Supplying a three-way valve (8), which is proportionally controlled by a circulation pump (7) connected to the liquid, which is a heat exchange medium, and an expansion tank (3) and a temperature sensor (13), which handle the volume expansion according to the temperature change of the liquid. The side heat exchanger 5, the exhaust side heat exchanger 6, and the circulation pump 7 side flow path are regulated, and then separate to the air supply blower 4, the exhaust blower 4 'and the circulation pump 7. The reference numerals 9 and-12 denote slide valves.
이와 같이 구성된 본 고안의 작용 및 효과를 상세히 설명하면, 급기측 덕트(1)를 통해 찬공기가 급기되는 경우 배기측 덕트(2)에서는 더운 공기가 배출되고 이와는 반대로 급기측 덕트(1)를 통해 더운 공기가 급기되는 경우 배기측 덕트(2)에서는 더운 공기가 배출되고 이와는 반대로 급기측 덕트(1)를 통해 더운 공기가 급기되는 경우 배기측 덕트(2)에서는 찬공기가 배출되는데 이것은 산업용 공조기에 의한 공기량의 평형을 상대적으로 맞추기 위해 배기되는 공기량과 급기되는 공기량은 거의 같기 때문이다.Referring to the operation and effect of the present invention configured in this way, when the cold air is supplied through the air supply side duct (1), the hot air is discharged from the exhaust side duct (2) and on the contrary through the air supply side duct (1) When hot air is supplied, hot air is discharged from the exhaust side duct (2), and conversely, when hot air is supplied through the air supply duct (1), cold air is discharged from the exhaust side duct (2). This is because the amount of air to be exhausted and the amount of air to be supplied are almost the same in order to balance the amount of air relatively.
이와 같은 상태에서 급기측의 송풍기(4)와 배기측의 송풍기(4') 및 순환펌프(7)가 인터록된 별도의 전원이 인가되면 이와 동시에 순환펌프(7)가 구동되어 팽창탱크(3)에 저장된 물 또는 에틸렌 글리콜 수용액이 폐회로로 형성된 배관 파이프(15)를 통해 실선화살표(→)방향으로 강제 순환된다.In such a state, when a separate power source in which the air blower 4 on the air supply side, the air blower 4 'on the exhaust side, and the circulation pump 7 is interlocked is applied, the circulation pump 7 is simultaneously driven to expand the expansion tank 3. Water or ethylene glycol aqueous solution stored in the water is forcedly circulated in the direction of the solid arrow (→) through the piping pipe 15 formed by the closed circuit.
이때 순환되는 열전달 매체의 액체가 배기측 덕트(2)내의 열교환기(6)를 통해 반복 순환되면서 배개되는 공기의 열을 수거하게 되고, 또 급기측 덕트(1)내의 열교환기(5)를 통해 반복 순환되면서 급기되는 공기의 열을 빼앗거나, 전달하게 된다.At this time, the liquid of the circulating heat transfer medium is repeatedly circulated through the heat exchanger 6 in the exhaust side duct 2 to collect the heat of the exhausted air, and through the heat exchanger 5 in the air supply side duct 1. As it is repeatedly circulated, the heat of the supplied air is taken away or transferred.
이러한 과정이 반복되면서 배기되는 공기의 열을 순환되는 액체에 전달시켜 점차 상승 또는 하강케한 다음 급기측 열교환기(5)를 통해 실내로 공급되는 급기측 공기에 더욱가온, 냉 되어지나, 설정된 온도 이상으로 상승 또는 하강될때 온도 감지기(13)에 의해 3방변밸브(8)가 급기측 열교환기(5)를 통해 순환되는 유로를 즉시 차단시킨다.As this process is repeated, the heat of the exhausted air is transferred to the circulating liquid and gradually raised or lowered, and then further heated or cooled to the supply side air supplied to the room through the supply side heat exchanger 5, but at a predetermined temperature. When the temperature rises or rises above, the three-way valve 8 immediately blocks the flow path circulated through the air supply side heat exchanger 5.
이때에도 순환펌프(7)는 계속 가동되는 상태이므로, 열전달 매체의 액체는 도면의 점선 화살표(→)방향으로 순환되고, 급기측 덕트(1)로 급기되는 공기가 열교환기(5)를 통해 열교환된 순환 액체의 온도와 관계없이 공기조화기(도면미도시)로 부터 공급되는 공기 온도 그대로 질내에 공급하게 된다.Since the circulation pump 7 continues to operate at this time, the liquid in the heat transfer medium is circulated in the direction indicated by the dotted line arrow (→) in the drawing, and the air supplied to the air supply side duct 1 exchanges heat through the heat exchanger 5. Irrespective of the temperature of the circulating liquid, the air temperature supplied from the air conditioner (not shown) is supplied in the vagina as it is.
그러던 중 상기 열교환기(5)와 (6)사이에 계속 순환되면서 열교환된 액체로 인해 더욱 온도 상승 내지 하락 하게 되면, 이와 동시에 급기측 열교환기(5)를 통해 급기되는 공기 온도가 과열, 냉 온도 감지기(14)에 의해 즉시 순환펌프(7)를 정지시키면서 열전달 매체의 액체 순환을 멈추게한다.Meanwhile, when the temperature rises or falls further due to the heat-exchanged liquid while continuously circulating between the heat exchangers 5 and 6, at the same time, the air temperature supplied through the air supply side heat exchanger 5 is superheated and cold. The sensor 14 stops the liquid circulation of the heat transfer medium while immediately stopping the circulation pump 7.
그러나 순환펌프(7)에 의해 강제 순환되는 열전달 매체의 액체가 계속 순화되는 반복 과정을 통해 설정된 온도에 도달할때 3방변 밸브를 조절하는 온도 감지기(13)는 급기되는 공기의 온도에 따라 겨울철에는 약간 높게, 여름철에는 약간 낮게 온도 조절할 수 있으므로 이에 셋팅된 온도 범위로 떨어질때에는 다시 3방변 밸브(8)의 유로를 초기의 상태로 개방시키고, 또한, 설정온도 이상으로 과열, 과냉될때 정지된 순환펌프(7)는 열교환된 급기측 공기 온도에 따라 셋팅된 온도 범위로 떨어질때 제가동하게 되면서 전술된 처음 상태의 과정으로 반복하게 되는 것이다.However, when the liquid of the heat transfer medium forcedly circulated by the circulation pump 7 reaches the set temperature through a repetitive process in which the liquid is continuously purified, the temperature sensor 13 for adjusting the three-way valve is used in winter in accordance with the temperature of the supplied air. The temperature can be adjusted slightly higher and slightly lower in summer, so when the temperature range is lowered, the flow path of the three-way valve 8 is opened to the initial state again, and the circulation pump stopped when it is overheated or overcooled above the set temperature. (7) repeats the above-described initial process as it starts to move when it falls to the set temperature range according to the heat exchanged air supply side air temperature.
따라서 위와 같이 되는 본 고안에 의하면 공기대 액체 열교환기 2대를 배기측과 급기측 덕트에 내설한 폐회로 형성으로 순환펌프(7)에 의해 강제 순환되는 열교환 매체의 액체가 배기되는 공기에서 열을 수수한다거나, 또는 급기되는 공기에서 열을 빼앗거나, 전달하게 되어 결국 급기되는 공기의 온도를 더욱 가열 내지 가냉하게 되므로서 급기측 부하를 줄일 수 있는 한편 많은 에너지를 절감 시킬 수 있고, 밀폐된 튜브내의 액체를 증발키 위해 별도의 가열기와 또한 증발되는 기체를 액화시키기 위한 보조 기구의 압측장치가 필요치 않게 되므로서 설치 및 생산 코스트의 상승을 억제하게 될뿐아니라, 과열, 과냉 될때 이에 대한 안전장치가 부가되어 사용자의 안전을 기할 수 있으므로, 매우 괄목할만한 효과가 있는 고안인 것이다.Therefore, according to the present invention as described above, two air-to-liquid heat exchangers are formed in a closed circuit built in the exhaust side and the air supply-side duct to receive heat from the air in which the liquid of the heat-exchange medium forcedly circulated by the circulation pump 7 is exhausted. Or draw heat from the air that is supplied to it, or transfer it, thereby heating or cooling the temperature of the air that is supplied, thereby reducing the load on the supply side and saving a lot of energy, and the liquid in the sealed tube. This eliminates the need for a separate heater and a pressure gauge of the auxiliary mechanism to liquefy the evaporated gas, thereby suppressing an increase in installation and production costs, as well as a safety device for overheating and overcooling. Because it can ensure the safety of the user, the design is very remarkable effect.
