Description
본 고안은 흡수식 냉난방기에 관한 것으로, 특히 흡수식 냉난방기에 형성되는 불응축가스(N2,H2)를 흡수기와 연결되어 있는 추기구동펌프의 구동력으로 흡수액(리튬브로마이드 수용액)을 중압 이젝트, 저압 이젝트로 보내 흡수식 냉난방기 몸체로부터 불응축 가스를 추출하여 기액분리실에서 흡수액과 불응축가스를 분리하여 흡수액은 흡수기로 보내고, 불응축가스는 가스저장실로 보내어 가스저장실에 불응축가스량이 많아져 압력이 올라가면 기액 분리기의 흡수액 레벨이 낮아져 이것을 감지하여 진공펌프에 의해 자동으로 대기로 배출시키는 흡수식 냉난방기의 불응축가스 추기장치에 관한 것이다.The present invention relates to an absorption type air conditioner, and in particular, a non-condensable gas (N 2 , H 2 ) formed in the absorption type air conditioner is driven by a driving force of a driving mechanism pump connected to the absorber (lithium bromide aqueous solution) as a medium pressure ejector and a low pressure ejector. Extract the non-condensable gas from the absorption type air-conditioner body, separate the absorbed liquid and non-condensed gas from the gas-liquid separation chamber, and send the absorbed liquid to the absorber, and send the non-condensed gas to the gas storage chamber to increase the amount of non-condensed gas in the gas storage chamber. The present invention relates to a non-condensing gas scavenging device of an absorption type air conditioner which detects the level of the absorbent liquid of the separator and automatically discharges it to the atmosphere by a vacuum pump.
일반적으로 2중 효용 흡수식 냉난방 냉방사이클은 고온재생기를 버너로 가열하면 내부의 LiBr 희용액이 비등하여 냉매증기의 기포와 LiBr의 중간 농용액이 함께 열기포 펌프의 원리에 의하여 양액관으로 상승하여 분리기에 의해 냉매증기와 중간용액이 분리된다.In general, the dual-effect absorption air-conditioning / cooling cycle uses a burner to heat the LiBr dilute solution, and the bubbles of the refrigerant vapor and the intermediate concentrated solution of LiBr rise to the nutrient solution pipe by the principle of a hot air pump. The refrigerant vapor and the intermediate solution are separated.
분리된 중간용액은 고온열교환기에서 희용액과 열교환한 후 저온재생기로 들어간다.The separated intermediate solution is exchanged with the rare solution in the high temperature heat exchanger and then enters the low temperature regenerator.
한편, 분리기에서 분리된 냉매증기는 저온재생기에 들어가서 열원이 되어 저온재생기로 들어간다.Meanwhile, the refrigerant vapor separated from the separator enters the low temperature regenerator and becomes a heat source to enter the low temperature regenerator.
한편, 분리기에서 분리된 냉매증기는 저온재생기에 들어가서 열원이 되어 저온재생기에 들어운 중간용액을 가열, 비등시키고 자신은 응축되어 응축기로 들어가고 이때의 중간용액은 냉매증기를 방출한 후 농용액이 되어 저온열교환기에서 희용액과 열교환한 후 흡수기로 들어간다.On the other hand, the refrigerant vapor separated from the separator enters the low temperature regenerator and becomes a heat source to heat and boil the intermediate solution contained in the low temperature regenerator, and condenses itself to enter the condenser. At this time, the intermediate solution discharges the refrigerant vapor and becomes a concentrated solution. Heat exchange with rare solution in low temperature heat exchanger and then enter absorber.
방출된 냉매증기는 응축기로 들어가 응축기 코일표면에 접촉하여 내부에서 흐르는 냉각수에 의해 냉각, 응축해서 냉매인 물이되어 하부에 고인후, 증발기로 들어가서 증발기 코일 표면에 적하 코일표면에서 즉시 증발하여 코일을 통과하는 순환수로부터 열을 빼앗아 냉수로 만든다. 또 여기서 증발한 냉매증기는 흡수기에서 농용액에 흡수되어 희용액이 되고 용액펌프에 의해 저온, 고온 열교환기를 거쳐 고온재생기로 돌아온 다음 이를 반복한다.The released refrigerant vapor enters the condenser, contacts the surface of the condenser coil, cools and condenses it with the cooling water flowing inside, becomes the refrigerant water, accumulates at the bottom, enters the evaporator, and drips on the surface of the evaporator coil and immediately evaporates from the coil surface. It takes heat away from the circulating water and makes it cold. In addition, the refrigerant vapor evaporated here is absorbed into the concentrated solution in the absorber to become a rare solution, and the solution pump returns to the high temperature regenerator through a low temperature and high temperature heat exchanger and repeats this.
기기내의 불응축가스가 존재하면 중압부 온도상승에 따라 고압부 온도상승과 흡수능력저하에 따른 냉동능력저하에 따른 가스소비량이 증가하여 냉동효율이 떨어지는 문제가 있다.If there is non-condensable gas in the device, there is a problem that the refrigeration efficiency decreases due to the increase in gas consumption due to the increase in temperature of the high pressure part and the decrease in freezing capacity due to the decrease in absorption capacity.
도 1 은 종래의 일반적인 소형 흡수식 냉난방기의 개략도이다. 미설명부호 61은 흡수식 냉난방기를 나타낸다. 상기 흡수식 냉난방기의 흡수기(1)에서 발생되는 불응축가스는 저압기체관(15)을 통해 냉매증기와 불응축가스는 냉각수코일에 의하여 저압이된 보조흡수기(22)를 통과하여 냉매증기는 농용액 공급관(23)에서 공급되는 보조흡수기(22)의 농용액에 흡수되어 희용액이 되어 불응축가스와 함께 저압기액 혼합관(13)을 통하여 기액 분리실(7)에 저장된다. 상기 기액분리실(7)은 리튬브로마이드(LiBr) 수용액을 흡수액 순환관(18)을 통하여 흡수기(1)로 보내고, 불응축가스는 불응축 가스 공급관(17)을 통하여 가스저장실(9)로 보내게 된다.1 is a schematic diagram of a conventional general miniature absorption air conditioner. Reference numeral 61 denotes an absorption air conditioner. The non-condensable gas generated in the absorber 1 of the absorption type air conditioner is passed through the low pressure gas pipe 15 through the refrigerant vapor and the non-condensed gas through the subsidiary absorber 22 which is low pressured by the cooling water coil. It is absorbed by the concentrated solution of the auxiliary absorber 22 supplied from the supply pipe 23, becomes a rare solution, and is stored in the gas-liquid separation chamber 7 through the low pressure gas liquid mixing pipe 13 together with the non-condensable gas. The gas-liquid separation chamber 7 sends a lithium bromide (LiBr) aqueous solution to the absorber 1 through the absorbent liquid circulation pipe 18, and the non-condensable gas is sent to the gas storage chamber 9 through the non-condensed gas supply pipe 17. It becomes.
상기 가스 저장실(9)로 보내진 가스는 진공밸브(41)를 통해 외부로 배출된다.The gas sent to the gas reservoir 9 is discharged to the outside through the vacuum valve 41.
종래 흡수식 냉난방기의 경우 보조흡수기와 흡수기의 압력차가 적어 불응축가스가 흡수기에서 보조흡수기로 가는데 어려움이 있고, 냉방시시템 가동중에는 중압부분(응축기, 저온재생기)에서 발생되는 불응축가스를 추출할 수 없으며,(시스템 운전중 중압부분은 액봉으로 불응축가스가 통과하지 못함) 시스템 운전중에만 추기장치가 가동되어 기기 정지중에는 불응축가스를 추출할 수 없고 가스 저장실에 포집된 불응축가스의 배출을 일정량이 포집될 때까지 하지 않을 경우 가스 저장실내에 있는 불응축 가스가 몸체로 역류를 하는 문제점이 있었다.In the case of conventional absorption air conditioners, the pressure difference between the auxiliary absorber and the absorber is small, so that it is difficult for the non-condensable gas to go from the absorber to the auxiliary absorber, and during operation of the cooling system, it is possible to extract the non-condensable gas generated in the middle pressure part (condenser, low temperature regenerator). (In the middle of the system operation, the non-condensable gas does not pass through the liquid rod.) The extraction device operates only during the system operation, so that non-condensable gas cannot be extracted while the machine is stopped. There was a problem that the non-condensable gas in the gas reservoir back flow into the body if not until a certain amount is collected.
본 고안은 전술한 문제점을 감안하여 안출한 것으로서, 본 고안의 목적은, 흡수식 냉난방기에서 발생하는 불응축가스를 저압 이젝터, 중압이젝터를 추기구동펌프의 구동력으로(작동매체 희용액) 가동시켜 고압부인 고온재생기, 중압부인 저온재생기, 응축기(고압부와 중압부는 관통), 저압부인 증발기, 흡수기 등 시스템 전부분의 불응축가스를 추출하고 기액분리실에서 분리된 불응축가스를 가스 저장실에서 저장시켜 불응축가스 저장량을 기액분리기의 액레벨로 측정하여 자동으로 대기로 배출하며, 시스템 정지중에도 추기구동펌프를 가동하여 기기내 불응축가스를 추출할 수 있는 흡수식 냉난방기의 불응축가스 추기장치를 제공하는데 그 목적이 있다.The present invention has been made in view of the above-described problems, and the object of the present invention is to operate a non-condensable gas generated in an absorption type air conditioner by operating a low pressure ejector and a medium pressure ejector with a driving force of a driving mechanism pump (operating medium rare solution). Extracts non-condensable gas from all parts of the system such as high temperature regenerator, low temperature regenerator, condenser (high pressure part and medium pressure part), low pressure evaporator and absorber, and stores non-condensed gas separated from gas-liquid separation chamber in gas storage room. It provides a non-condensable gas scavenging device of absorption type air conditioner which can measure the gas storage amount by the liquid level of gas-liquid separator and automatically discharge it to the atmosphere, and operate the extraction mechanism driving pump even during system stop. There is this.
전술한 목적을 달성하기 위하여, 본 고안은, 흡수기(1), 저압용 이젝트(5), 중압용 이젝트(6), 기액 분리실(7),가스 저장실(9) 및 추기구동펌프(8)를 포함한 흡수식 냉난방기에 있어서, 상기 기액분리실(7)은 내부의 상측으로 액레벨에 의한 가스저장실(9)의 불응축가스량을 제어가능하게 레벨스위치(30)을 형성하고, 상기 가스저장실(9)의 상부로 제 1 솔레노이드 밸브(45)와 연결하는 진공펌프(40)를 형성한 것을 특징으로 하는 흡수식 냉난방기의 불응축가스 추기장치를 제공한다.In order to achieve the above object, the present invention, the absorber (1), low pressure ejection (5), medium pressure ejection (6), gas-liquid separation chamber (7), gas storage chamber (9) and the driven mechanism pump (8) In the absorption type air conditioner including the, the gas-liquid separation chamber (7) forms a level switch (30) to control the amount of non-condensing gas in the gas storage chamber (9) by the liquid level to the upper side of the inside, the gas storage chamber (9) It provides a non-condensing gas scavenging device of the absorption type air conditioner, characterized in that the vacuum pump 40 is connected to the first solenoid valve 45 in the upper portion of the).

도 2는 본 고안의 일실시예에 의한 흡수식냉난방기의 개략도이고, 도 3은 본 고안의 일실시예에 의한 플로우 차트를 나타낸다. 흡수식 냉난방기의 저압부분인 흡수기(1), 증발기(2)는 저압 기체관(15)을 통하여 저압이젝트(5)와 연결되고 중압부분인 응축기(3), 저온재생기(4)는 중압 기체관(16)을 통하여 중압 이젝트(6)와 연결되어 흡수기(1)와 연결된 추기구동펌프 입구관(11)을 지난 희용액이 추기구동펌프(8)에 의해 압력이 상승되어 추기구동펌프 출구관(12)에서 저압이젝트(5)와 중압이젝트(6)의 작동매체(희용액)로 공급시켜 저압부분과 중압부분의 불응축가스와 냉매증기는 저압기체관(15), 중압기체관(16)을 통하여 흡입한다.Figure 2 is a schematic diagram of an absorption type air conditioner according to an embodiment of the present invention, Figure 3 shows a flow chart according to an embodiment of the present invention. The absorber (1) and evaporator (2) of the low pressure part of the absorption air-conditioner are connected to the low pressure eject (5) through the low pressure gas pipe (15), and the condenser (3) and the low temperature regenerator (4) of the medium pressure gas pipe ( 16. The rare solution, which is connected to the medium pressure ejector 6 and passed through the pendulum driven pump inlet pipe 11 connected to the absorber 1, is increased in pressure by the pendulum driven pump 8, thereby causing the pendulum driven pump outlet pipe 12 ) Is supplied to the working medium (solution solution) of the low pressure ejector 5 and the medium pressure ejector 6, and the non-condensable gas and the refrigerant vapor of the low pressure part and the medium pressure part are supplied through the low pressure gas pipe 15 and the medium pressure gas pipe 16. Inhale.
흡입된 불응축가스와 냉매증기는 저압이젝트(5)와 중압이젝트(6)의 작동매체와 함께 저압기액 혼합관(13), 중압기액 혼합관(14)을 통하여 기액분리실(7)로 들어간다. 상기 기액분리실(7)에서 냉매증기는 희용액에 흡수되어 흡수액 순환관(18)을 통하여 흡수기(1)로 가고 불응축가스는 불응측가스 공급관(17)을 통하여 가스저장실(9)에 저장이 된다.The suctioned non-condensable gas and the refrigerant vapor enter the gas-liquid separation chamber 7 through the low pressure gas liquid mixing tube 13 and the medium pressure gas liquid mixing tube 14 together with the working medium of the low pressure ejector 5 and the medium pressure ejector 6. In the gas-liquid separation chamber (7), the refrigerant vapor is absorbed by the rare solution to the absorber (1) through the absorbent liquid circulation pipe (18), and the non-condensable gas is stored in the gas storage chamber (9) through the non-condensable gas supply pipe (17). Becomes
상기 기액분리실(7)의 상부로는 레벨스위치(30)를 형성하며 상기 레벨스위치(30)는 가스저장실(9)의 압력에 따라 상하로 이동할 수 있도록 설치한다. 상기 레벨스위치(30)에는 타이머(51)를 연결설치하며 상기 가스저장실(9)은 진공펌프(40)와 연결되도록 제 1 솔레노이드 밸브(45)를 형성한다.The upper portion of the gas-liquid separation chamber (7) forms a level switch 30, the level switch 30 is installed so as to move up and down in accordance with the pressure of the gas storage chamber (9). A timer 51 is connected to and installed in the level switch 30, and the gas storage chamber 9 forms a first solenoid valve 45 to be connected to the vacuum pump 40.
또한, 상기 흡수기(1)는 불응축가스 추출관 1(19)을 형성하여 제 2 솔레노이드 밸브(50)와 연결한다.In addition, the absorber 1 forms a non-condensable gas extraction tube 1 (19) to connect with the second solenoid valve 50.
전술한 구성에 대한 본 고안의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the present invention with respect to the above-described configuration in detail as follows.
상기 기액분리실(7)은 흡수기(1), 저압 이젝트(5), 중압 이젝트(6), 가스저장실(9)과 연결되어 있고 상기 가스 저장실(9)의 압력(약 80 Torr)이 높을 경우 레벨 스위치(30)의 수위가 변동한다. 이 신호에 의하여 진공펌프(40)를 구동시킨 후 제 1 솔레노이드 밸브(45)를 열어 가스를 대기로 배출시키며 상기 레벨스위치(30)의 작동범위는 약 2-3 Torr 밖에 형성되지 않기 때문에 가스저장실(9)의 불응축가스를 충분히 배출시키려면 타이머(51)로 일정시간 돌게하여 충분히 불응축가스를 배출시키며 제 1 솔레노이드 밸브(45)를 닫고 진공펌프(40)의 구동을 정지시킨다.The gas-liquid separation chamber 7 is connected to the absorber 1, the low pressure eject 5, the medium pressure eject 6, and the gas storage chamber 9, and the pressure of the gas storage chamber 9 is high (about 80 Torr). The water level of the level switch 30 fluctuates. After driving the vacuum pump 40 according to this signal, the first solenoid valve 45 is opened to discharge gas into the atmosphere, and the operating range of the level switch 30 is only about 2-3 Torr. To sufficiently discharge the non-condensable gas of (9), the timer 51 is turned for a predetermined time to discharge the non-condensed gas sufficiently, the first solenoid valve 45 is closed, and the driving of the vacuum pump 40 is stopped.
또한, 흡수식 냉난방기를 장시간 운전하지 않을시는 시스템내 불응축가스가 많이 존재할 경우 저압이젝트(5), 중압이젝트(6)의 구동으로 불응축가스를 대기로 배출하는 경우 장시간이 소요되므로 제 2 솔레노이드 밸브(50)를 열어 진공펌프(40)로 직접 대기로 배출할 수 있다. 이때는 상기 진공펌프(40)를 수동으로 작동할 수 있다.In addition, when there is a large amount of non-condensable gas in the system when the absorption air conditioner is not operated for a long time, when the non-condensed gas is discharged to the atmosphere by driving the low pressure ejector 5 and the medium pressure ejector 6, the second solenoid valve ( 50) can be discharged to the atmosphere directly to the vacuum pump 40. In this case, the vacuum pump 40 may be manually operated.
또한, 운전정지중 추기구동펌프(8)를 가동시켜 운전가동중 보다 더 효과적으로 불응축가스를 추출할 수 있다.In addition, it is possible to extract the non-condensable gas more effectively than during operation by operating the driving mechanism pump 8 during the operation stop.
전술한 구성과 작용에 의한 본 고안의 효과는, 저압부분 및 중압부분측의 불응축가스를 추출하여 시스템의 불응축가스를 시스템 전부분에서 추출할 수 있고 기액분리기의 내부상측으로 레벨스위치와 연동하는 타이머를 설치하여 흡수식 냉난방기에서 발생되는 불응축가스를 효율적으로 추출할 수 있으며 가스저장실의 사이즈도 줄일수 있다.The effect of the present invention by the above-described configuration and action, it is possible to extract the non-condensable gas of the low pressure portion and the medium pressure portion side to extract the non-condensable gas of the system from all parts of the system and interlock with the level switch inside the gas-liquid separator By installing a timer that can efficiently extract the non-condensing gas from the absorption air conditioner and reduce the size of the gas storage chamber.
