Description

흡수식 냉동기의 계면활성제 회수장치Surfactant Recovery Device for Absorption Chiller

첨부된 도면은 본 발명의 계통도이다.The accompanying drawings are schematic diagrams of the invention.

본 발명은 흡수식 냉동기의 계면활성제 회수장치에 관한 것이다. 즉, 냉난방의 공조기에 사용되는 계면활성제를 분리하기 위하여 응축기와 증발기를 연결하는 배관사이에 "U"자관을 1개 또는 2개를 직렬로 설치하고, 오우버 플로우관을 만들어 저온 발생기와 연결시켜 주므로써, 응축기에서 응축된 냉매는 "U"자 관을 통과하여 증발기와 연결된 배관을 통해서 증발기로 유입된다.The present invention relates to a surfactant recovery apparatus of the absorption chiller. That is, in order to separate surfactant used in air conditioning and air conditioning, one or two “U” tubes are installed in series between the pipes connecting the condenser and the evaporator, and the overflow tube is connected to the low temperature generator. By condensation, the refrigerant condensed in the condenser enters the evaporator through a pipe connected to the evaporator through the "U" tube.

아울러, 냉매에 혼합되어 있는 옥칠 알콜을 냉매보다 가볍기 때문에 냉매가 "U"자 관을 통과할때 "U"자관의 일측상단에 축점됨과 동시에, 일정량 이상 축적되면 오우버 플로우관을 통해 저온 발생기로 흘러들어가는 것이다.In addition, because the oxyl alcohol mixed in the refrigerant is lighter than the refrigerant, when the refrigerant passes through the "U" tube, the refrigerant is accumulated at one side of the upper side of the "U" tube, and when a predetermined amount or more is accumulated, it is transferred to the low temperature generator through the overflow tube. It is flowing.

이렇게 하므로써 냉매과 계면활성제를 분리시키게 되는 것이다. 그러므로, 옥칠 알콜등의 계면활성제가 증발기로 유입되는 것에 의해 흡수식 냉동기의 성능이 저하되는 것을 방지할 수 있다.In this way, the refrigerant and the surfactant are separated. Therefore, deterioration of the performance of the absorption chiller can be prevented by the inflow of surfactant such as oxyl alcohol into the evaporator.

즉, 첨부된 도면에 의하연 상세히 설명하면 다음과 같다.That is, when described in detail by the accompanying drawings as follows.

냉매순환펌프(9)에 의해서 증발기(2)의 전열판위에 냉매가 산포되면, 냉수라인(15)의 내부를 흐르고 있는 냉수와 열을 교환하여 냉매가 일부 증발하면서 냉매증기가 발생되고, 냉수라인(15)내부의 냉수는 증발잠열을 빼앗겨 온도가 하락하여 냉방용으로 사용된다.When the refrigerant is scattered on the heat transfer plate of the evaporator 2 by the refrigerant circulation pump 9, the refrigerant is partially evaporated by exchanging heat with the cold water flowing inside the cold water line 15, whereby the refrigerant vapor is generated. 15) The cold water inside is deprived of latent heat of evaporation and the temperature decreases and is used for cooling.

그리고, 증발기(2)에서 발생된 냉매증기는 흡수식(1)의 전열판위에 산포되는 응용액에 흡수되어 응용액은 치용액으로 된다.The refrigerant vapor generated in the evaporator 2 is absorbed by the application liquid scattered on the heat transfer plate of the absorption formula (1), and the application liquid becomes a dental solution.

따라서, 흡수기(1)내의 치용액은 용액순환펌프(10)에 의하여 고온열교환기(8) 및 저온열교환기(7)를 경유해 고온발생기(5)로 공급되고, 고온발생기(5)내의 버너(6)로 가열하면 냉매증기가 발생된다. 그러므로, 흡수액은 중간농도의 용액으로 되며, 일부는 저온발생기(3)로 공급된다. 또한, 고온발생기(5)에서 발생된 일부의 냉매증기는 다시 저온발생기(3)의 전열관내로 유입되어 고온발생기(5)에서 저온발생기(3)로 공급된 중간농도의 용액을 가열하면서 증발기(2)로 유입되어 냉매를 보충해 준다. 그리고, 저온발생기(3)에서 발생한 냉매증기는 응축기(4)로 유입되고, 응축기 관내를 흐르는 냉각수에 의하여 응축되어 증발기(2)로 유입되어 냉매를 보충해 주는 것이다. 이와같이 흡수 싸이클이 형성되어 지속적으로 냉수를 제조할 수 있는 것이다.Therefore, the tooth solution in the absorber 1 is supplied to the high temperature generator 5 via the high temperature heat exchanger 8 and the low temperature heat exchanger 7 by the solution circulation pump 10, and the burner in the high temperature generator 5 is supplied. Heating to (6) generates refrigerant vapor. Therefore, the absorbent liquid becomes a solution of medium concentration, and part of it is supplied to the low temperature generator 3. In addition, some of the refrigerant vapor generated in the high temperature generator (5) is introduced into the heat transfer tube of the low temperature generator (3) again while heating the medium concentration solution supplied from the high temperature generator (5) to the low temperature generator (3). ) To replenish refrigerant. In addition, the refrigerant vapor generated in the low temperature generator (3) is introduced into the condenser (4), condensed by the cooling water flowing in the condenser tube and introduced into the evaporator (2) to replenish the refrigerant. As such, the absorption cycle is formed to continuously produce cold water.

즉, 상기와 같은 반복 싸이클 운동으로 증발기(2)에서 발생된 냉매증기를 흡수기(1)에서 흡수액으로 흡수하는데, 이를 용이하게 흡수하게 위하여 옥칠 알콜등이 계면활성제를 흡수액에 첨가시켜 준다.That is, the refrigerant cycle generated in the evaporator 2 is absorbed into the absorbent liquid in the absorber 1 by the repeated cycle motion as described above. In order to easily absorb the refrigerant, oxyl alcohol or the like is added to the absorbent liquid.

그러나, 이 계면활성제는 고온발생기(5)와 저온발생기(3)에 유입되어 냉매증기가 발생될때 냉매증기에 수반되어 냉매에 섞여들어가 증발기(2)에 축적되어 성능을 저해시키는 요인이 된다. 따라서, 본 발명에서는 냉매와 계면활성제를 분리시키기 위하여 응축기(4)와 증발기(2)를 연결하는 배관사이에 "U"자관(11)(12)을 1개 또는 2개를 직렬로 연결 설치하며, 오우버 플로우관(13)(14)을 만들어 저온발생기(3)와 연결하여 주면 응축기(4)에서 응축된 냉매는 "U"잔관(11)(12)을 통과하여 증발기(2)와 연결된 배관(17)을 통해서 증발기(2)로 유입된다. 이때, 냉매에 혼합된 옥칠알콜은 냉매보다 가볍기 때문에 냉매가 "U"자관(11)(12)을 통과할때 "U"자관 상단 일측에 집합소(A)(B)에 축적된다. 따라서, 옥칠알콜이 집합소(A)(B)에 일정량 이상 축적되면 오우버 플로우관(13)(14)을 통해 저온발생기(3)로부터 흘러 들어가게 되는 것이며, 냉매와 계면활성제를 분리시킬 수 있으므로 옥칠알콜등의 계면활성제가 증발기(2)로 유입되는 것을 방지하여 흡수식 냉동기의 성능이 저하되는 것을 방지할 수 있다.However, when the surfactant is introduced into the high temperature generator 5 and the low temperature generator 3 and the refrigerant vapor is generated, the surfactant is mixed with the refrigerant vapor in the refrigerant vapor and accumulates in the evaporator 2, thereby degrading the performance. Therefore, in the present invention, in order to separate the refrigerant and the surfactant, one or two “U” magnetic pipes 11 and 12 are connected in series between the pipes connecting the condenser 4 and the evaporator 2. When the overflow pipes 13 and 14 are connected to the low temperature generator 3, the refrigerant condensed in the condenser 4 is connected to the evaporator 2 through the “U” residual pipes 11 and 12. It flows into the evaporator 2 through the pipe 17. At this time, since the oxyl alcohol mixed in the refrigerant is lighter than the refrigerant, when the refrigerant passes through the "U" tube 11, 12 is accumulated in the assembly (A) (B) on one side of the upper end of the "U" tube. Therefore, when the oxyl alcohol accumulates in the aggregate (A) (B) by a predetermined amount or more, it flows out of the low temperature generator (3) through the overflow pipes (13) and (14), and the refrigerant and the surfactant can be separated from the oxyl Surfactants, such as alcohol, can be prevented from entering the evaporator 2, so that the performance of the absorption refrigerator can be prevented from being lowered.
