본 고안은 공기조화기(이하 공조기라 약칭함)에 관한 것으로, 특히 암모니아(NH3) 흡수식 냉반방기에서 재생기내의 강용액(Strong Solution)을 가열하여 냉매증기를 발생시킬 때 냉매에 포함된 흡수제(H2O)를 완전히 제거하여 순도가 높은 암모니아 냉매증기를 얻도록 한 공조기의 정류장치에 관한 것이다.The present invention relates to an air conditioner (hereinafter, referred to as an air conditioner), and an absorbent included in the refrigerant when generating a refrigerant vapor by heating a strong solution in the regenerator in an ammonia (NH 3 ) absorption chiller. It relates to an air conditioner stop that completely removes H 2 O) to obtain a high purity ammonia refrigerant vapor.
종래의 공조기는 제1도에 도시된 바와 같이, 유입되는 강용액을 버너(4)로 가열하여 냉매증기를 발생시키는 재생기(1)와, 정류기 입구관(8)을 통해 유입되는 재생기(1)에서 얻어지는 냉매증기를 응축시켜 냉매증기에 포함된 흡수제를 제거하는 정류기(2)와, 상기 정류기(2)의 얻어지는 응축된 냉매증기를 열교환하는 응축기(3)로 구성되었다.As shown in FIG. 1, a conventional air conditioner includes a regenerator (1) for heating a flowing steel solution with a burner (4) to generate refrigerant vapor, and a regenerator (1) flowing through a rectifier inlet pipe (8). It consists of a rectifier (2) for condensing the refrigerant vapor obtained in to remove the absorbent contained in the refrigerant vapor, and a condenser (3) for heat-exchanging the condensed refrigerant vapor obtained in the rectifier (2).
도면중 미설명 부호 5는 재생기 열교환코일이고, 6은 정류기 열교환코일이며, 7은 응축기 열교환코일이고, 8은 정류기 입구관이고, 9는 정류기 토출관이고, 10은 응축기 출구관이며, 11은 정류기(2)에서 응축된 냉매액이 재생기(1)로 회수되도록 하는 응축된 액냉매 회수관이다.In the drawings, reference numeral 5 denotes a regenerator heat exchange coil, 6 is a rectifier heat exchange coil, 7 is a condenser heat exchange coil, 8 is a rectifier inlet tube, 9 is a rectifier discharge tube, 10 is a condenser outlet tube, and 11 is a rectifier. It is a condensed liquid refrigerant recovery pipe for allowing the refrigerant liquid condensed in (2) to be recovered to the regenerator (1).
이와같이 구성되는 종래 공조기는 재생기(1)에서 흡수기(Absorber:도면에는 미도시)로부터 유입되는 강용액을 버너(4)로 가열시켜 냉매증기(Refrigerant Vapor)를 발생시켜 정류기 입구관(8)을 통해 정류기(2)로 유입시키게 된다.The conventional air conditioner configured as described above is configured to generate a refrigerant vapor by heating a strong solution flowing from an absorber (not shown in the drawing) in the regenerator 1 with a burner 4 to generate a refrigerant vapor through the rectifier inlet pipe 8. To the rectifier (2).
이때, 묽어진 약용액(Weak Solution)은 재생기 열교환 코일(5)을 통하여 흡수기로 들어가게 된다.At this time, the diluted weak solution (Weak Solution) enters the absorber through the regenerator heat exchange coil (5).
한편, 재생기(1)에서 발생된 냉매증기에는 흡수제(H2O)가 냉매(NH3) 증기에 일부 포함된다(이는 NH3와 H2O의 비등점차가 크지 않기 때문이다).On the other hand, the refrigerant vapor generated in the regenerator 1 includes a part of the absorbent (H 2 O) in the refrigerant (NH 3 ) vapor (because the boiling point difference between NH 3 and H 2 O is not large).
따라서 정류기(2)는 유입되는 냉매증기에 포함된 흡수제를 응축시켜 정류하게 되고, 이때 발생되는 응축된 냉매액은 회수관(11)을 통해 재생기(1)로 재유입시키게 된다.Therefore, the rectifier 2 is condensed by condensing the absorbent contained in the refrigerant vapor flowing in, the condensed refrigerant liquid generated at this time is re-introduced into the regenerator 1 through the recovery pipe (11).
그리고, 정류된 암모니아 냉매증기는 정류기 출구관(9)으로 토출시켜 응축기(3)에 보내게 된다.The rectified ammonia refrigerant vapor is discharged to the rectifier outlet pipe 9 and sent to the condenser 3.
제2도는 이러한 작용을 하는 정류기의 상세구성을 보인 것이다.Figure 2 shows the detailed configuration of the rectifier to perform this action.
한편, 정류기(2)에서 응축열을 제거하기 위해서는 정류기 열교환코일(6)을 통하여 용액탱크(Solution Tank)로부터의 저온강용액을 사용한다.On the other hand, in order to remove the heat of condensation in the rectifier (2) is used a low-temperature steel solution from the solution tank (Solution Tank) through the rectifier heat exchange coil (6).
그러나 이러한 종래 공조기의 정류기는 열교환코일 내부로 흐르는 저온 강용액과 재생기에서 발생된 냉매증기의 열교환에 의해 응축된 냉매액은 중력에 의해 아래로 떨어지게 되는데, 이때 위에서 떨어지는 응축수는 아래 부분에 위치한 응축관의 액막을 두껍게 하여 열저항으로 작용을 하므로써 정류 효율이 저하되는 문제점이 있었다.However, in the conventional air conditioner rectifier, the refrigerant liquid condensed by the heat exchange of the low temperature steel solution flowing into the heat exchange coil and the refrigerant vapor generated in the regenerator falls down due to gravity, and the condensate falling from the top is condensed in the lower portion. By thickening the liquid film to act as a thermal resistance there was a problem that the rectification efficiency is lowered.
즉, 여러개의 수평관을 사용할 경우에 위로부터 n번째의 응축전달계수는 다음과 같은 식으로 나타낼 수 있다.In other words, when using multiple horizontal tubes, the nth condensation transfer coefficient from the top can be expressed as follows.
hn=h/n1/6 hn = h / n 1/6
따라서 다중 수평관을 사용하는 열교환코일에서는 위에서 응축된 응축수가 아래부분의 관에 영향을 미치므로 응축열전달 효과가 저하되어 정류 효율이 저하되는 것이다.Therefore, in the heat exchange coil using multiple horizontal tubes, the condensate condensed on the top affects the bottom tube, so that the condensation heat transfer effect is lowered and the rectification efficiency is lowered.
따라서 본 고안은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 암모니아(NH3) 흡수식 냉난방기에서 재생기내의 강용액(Strong Solution)을 가열하여 냉매증기를 발생시킬 때 냉매에 포함된 흡수제(H2O)를 완전히 제거하여 순도가 높은 암모니아 냉매증기를 얻도록 공조기의 정류장치를 제공하는데 있다.Therefore, the present invention is to solve all the problems of the prior art as described above, an object of the present invention is to generate a refrigerant vapor by heating the strong solution (strong solution) in the regenerator in the ammonia (NH 3 ) absorption air conditioner It is to provide an air conditioner stop to completely remove the included absorbent (H 2 O) to obtain a high-purity ammonia refrigerant vapor.
이러한 본 고안의 목적을 달성하기 위한 기술적 수단은 정류기 열교환코일을 이루는 각관의 양단이 지그재그로 배열되고 그 양단에 모인 응축수를 제거하도록 하는 플레이트를 구비하게 되는 것이다.The technical means for achieving the object of the present invention is to have a plate arranged to zigzag both ends of the tube forming the rectifier heat exchange coil to remove the condensed water collected at both ends.
이하, 본 고안을 첨부한 도면 제3도 및 제4도에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to FIGS. 3 and 4 of the accompanying drawings.
제3도는 본 고안에 의한 공조기의 정류장치 구성도로써, 도시된 바와 같이 열교환코일(13)을 이루는 다중관이 지그재그 형태로 구성되고, 열교환코일(13)의 각관 양단에 응축수를 제거하기 위한 플레이트(12)가 다수개 구비되어 구성되었다.3 is a stop configuration diagram of the air conditioner according to the present invention, as shown in the multi-pipe forming the heat exchange coil 13 is configured in a zigzag form, a plate for removing condensate water at each end of each pipe of the heat exchange coil (13) A plurality of (12) s were provided.
이와 같이 구성된 본 고안에 의한 정류장치는 재생기(제1도의 1)에서 토출되는 냉매 증기를 응축시켜 정류기 토출관(9)을 통해 응축기(제1도의 3)로 유입시키는 작용을 하게 되는데, 이때 응축시 발생되는 응축수는 열교환코일(13)의 중간 중간에 설치된 플레이트(12)에 의해 아래로 내려가면서 점점 제거된다.The stop value according to the present invention configured as described above condenses the refrigerant vapor discharged from the regenerator (1 in FIG. 1) to flow into the condenser (3 in FIG. 1) through the rectifier discharge pipe 9, wherein The condensate generated is gradually removed while descending by the plate 12 installed in the middle of the heat exchange coil 13.
여기서 열교환코일(13)을 이루는 다중관은 약간의 기울기를 주고 지그재그 형태로 배열하므로써 응축수가 아래로 내려가면서 각관의 양 끝에 모여지게 되며 제4도에 도시된 바와 같이 플레이트(12)에 형성된 다수개의 공(12a)에 의해 아래로 내려갈수록 응축수 양이 점점 줄어들게 되어 제거되는 것이다.Here, the multi-pipes constituting the heat exchange coil 13 are arranged in a zigzag form with a slight inclination so that the condensed water is collected at both ends of each pipe as it goes down, and as shown in FIG. As it goes down by the ball 12a, the amount of condensate is gradually reduced and is removed.
이렇게 아래로 내려가면서 응축수가 저감되면 맨 밑에 배열된 다중관에서는 응축수의 양이 거의 없으므로 응축열전달 효과가 높아져 정류 효율을 증가시킬 수 있다.When the condensate is reduced while going down, there is almost no amount of condensate in the bottom of the multi-pipe arranged, thus increasing the condensation heat transfer effect, thereby increasing the rectification efficiency.
상기에서 열교환코일(13)을 이루는 다중관의 직경은 상호 다르다.In the above, the diameters of the multi-pipes constituting the heat exchange coil 13 are different from each other.
이상에서와 같이 본 고안은 열교환코일을 이루는 다중관을 지그재그 형태로 배열하고 각관의 양단에 다수개의 공이 형성된 플레이트를 구비함으로써 응축수의 제거 효율이 높아져 상대적으로 응축열전달 효과가 증가되므로 정류효율을 증가시킬 수 있는 효과가 있다.As described above, the present invention arranges the multiple tubes constituting the heat exchange coil in a zigzag form and includes plates having a plurality of balls formed at both ends of each tube to increase the efficiency of removing condensate, thereby increasing the condensation heat transfer effect, thereby increasing the rectification efficiency. It can be effective.
