본 발명은 암모니아 흡수식 냉난방기에 관한 것으로서, 특히 정류기내로 유입되는 암모니아 냉매증기에서 수분을 제거하여 고농도의 암모니아 냉매증기를 형성하도록 한 것이다.The present invention relates to an ammonia absorption type air conditioner, and in particular, to remove water from the ammonia refrigerant vapor flowing into the rectifier to form a high concentration of ammonia refrigerant vapor.

종래의 암모니아 흡수식 냉난방기와 그 주변부의 구성은 제1도와 제2도에서와 같이 설명한다.The structure of the conventional ammonia absorption type air conditioner and its periphery is described as in FIG. 1 and FIG.

제1도와 제2도에서와 같이 버너(9)에서 발생되는 열을 가해주므로서 농도가 강한 작동용액(암모니아 수용액)으로부터 냉매인 암모니아를 증발시켜 암모니아 냉매증기를 얻음과 동시에 일부 암모니아 증발에 의해 생긴 농도가 약한 암모니아 수용액(이하 약용액이라함)을 만드는 재생기(1)와, 상기 재생기(1)에서 생성된 약용액이 용액냉각흡수기(3)로 유입되도록 형성된 약용액코일(10)과, 상기 재생기(1)에서 생성된 냉매증기로부터 함께 증발된 수분을 응축시켜 고농도의 암모니아 냉매증기를 얻도록 하는 정류기(2)와, 상기 정류기(2)내에 용액펌프(8)에서 펌핑된 강용액이 흐르도록 형성되어 냉매증기와 열교환하도록 하는 열교환코일(13)과, 상기 재생기(1)로부터 보내져 온 냉매증기를 실내기로부터 난방을 수행하고 온도가 떨어져서 들어온 냉각수를 사용하여 냉매증기로부터 열량을 빼앗아 액냉매로 응축시키는 응축기(5)와, 상기 응축기(5)로부터 보내져 온 액냉매를 실내기로부터 냉방을 수행하고 온도가 상승되어 들어온 냉수(11)에 의해 액냉매를 다시 증발시켜주어 냉매증기로 만들어 주는데, 이때 액냉매로 증발시키는데 필요한 열량은 실내기로부터 냉방을 수행하고 온도가 상승되어 들어온 냉수(11)로부터 공급되어진다.As shown in FIG. 1 and FIG. 2, by applying heat generated from the burner 9, ammonia, which is a refrigerant, is evaporated from a highly concentrated working solution (ammonia aqueous solution) to obtain ammonia refrigerant vapor, and at the same time, it is produced by partial ammonia evaporation. A regenerator (1) for producing a weak aqueous ammonia solution (hereinafter referred to as a medicinal solution), a medicinal solution coil (10) formed to flow into the solution cooling absorber (3), and A rectifier 2 for condensing water evaporated together from the refrigerant vapor generated in the regenerator 1 to obtain a high concentration of ammonia refrigerant vapor, and a river solution pumped from the solution pump 8 flows into the rectifier 2. Heat exchange coil 13 to exchange heat with the refrigerant vapor, and the refrigerant vapor sent from the regenerator 1 to be heated from the indoor unit, and to use the cooling water brought in at a lower temperature. To take heat from the refrigerant vapor and condense it into the liquid refrigerant, and to cool the liquid refrigerant sent from the condenser 5 from the indoor unit to cool the liquid refrigerant by the cold water 11 whose temperature has risen. It evaporates to make a refrigerant vapor. At this time, the amount of heat required to evaporate the liquid refrigerant is supplied from the cold water 11 that cools the room and enters the temperature.

상기와 같이 열량을 빼앗긴 냉수(11)는 다시 온도가 떨어진 후 실내기로 보내져 냉방을 수행하게 된다.As described above, the cold water 11 deprived of heat is sent to the indoor unit after the temperature drops again to perform cooling.

그리고 증발기(7)로부터 보내져 온 냉매증기를 재생기(1)내에 형성된 약용액코일(10)로부터 보내져 온 약용액이 용액냉각흡수기(3)를 통과하면서 냉매증기를 흡수하면 물냉각흡수기(4)는 응축기(5)를 거친 냉수(12)를 유입하여 약용액의 열을 빼앗아 원래의 재생기(1)의 초기 농도의 강용액으로 만든다.When the refrigerant vapor sent from the evaporator 7 absorbs the refrigerant vapor sent from the chemical solution coil 10 formed in the regenerator 1 through the solution cooling absorber 3, the water cooling absorber 4 Cold water 12, which has passed through the condenser 5, is introduced to take heat of the chemical solution into a strong solution of the initial concentration of the original regenerator (1).

상기 열량을 얻은 냉수(12)는 실내기로 난방을 위해 보내어진다.The cold water 12 from which the calories are obtained is sent for heating to the indoor unit.

그리고 재생기(1)로부터 증발된 냉매증기에는 암모니아(NH3)와 물(H2O)의 비등점차가 크지않아 냉매증기에 수분이 포함되어있다.The refrigerant vapor evaporated from the regenerator 1 includes moisture in the refrigerant vapor because the difference in boiling point between ammonia (NH 3 ) and water (H 2 O) is not large.

그래서 냉매증기와 함께 증발되는 수분을 정류기(2)가 응축시켜 고농도의 암모니아 냉매증기를 얻도록 하였다.Thus, the rectifier 2 condenses the water evaporated together with the refrigerant vapor to obtain a high concentration of ammonia refrigerant vapor.

이때 물을 응축시켜주는 매체는 용액펌프(8)로부터 보내져 온 강용액이 정류기(2)내에 감겨진 열교환코일(13)내를 흐르는 동안 냉매증기와 열교환을 통하여 냉매증기에 포함되어 있는 수분을 응축시킨다.At this time, the medium condensing water condenses the water contained in the refrigerant vapor through heat exchange with the refrigerant vapor while the steel solution sent from the solution pump (8) flows through the heat exchange coil (13) wound in the rectifier (2). Let's do it.

또한 냉매2중열교환기(6)는 응축기(5)로부터 나온 액냉매와 증발기(7)에서부터 나온 냉매증기와의 열교환을 통하여 액냉매를 증발기(7)내의 증발온도에 가깝게 내려주고, 냉매증기의 온도는 흡수기(3)(4)의 포화온도 가까이 온도를 올려주어 흡수현상을 가속화 시켜준다.In addition, the refrigerant double heat exchanger (6) lowers the liquid refrigerant close to the evaporation temperature in the evaporator (7) through heat exchange between the liquid refrigerant from the condenser (5) and the refrigerant vapor from the evaporator (7), The temperature increases the temperature near the saturation temperature of the absorber (3) (4) to accelerate the absorption phenomenon.

그리고 증발기(7)에서 증발하지 않은 미소량의 냉매도 증발시켜준다.In addition, a small amount of refrigerant not evaporated in the evaporator 7 is evaporated.

그러나 이러한 종래의 암모니아 흡수식 냉난방기는 재생기에서 생성된 암모니아 냉매증기에 수분이 포함되어 있어 고농도의 암모니아 냉매증기를 얻기 위해서는 재생기와 정류기사이에 액-증기분리기를 별도로 설치해야하는 문제점이 있었다.However, the conventional ammonia absorption type air conditioner includes moisture in the ammonia refrigerant vapor generated in the regenerator, so that a high concentration of ammonia refrigerant vapor has a problem of separately installing a liquid-vapor separator between the regenerator and the rectifier.

따라서 본 발명은 재생기로부터 생성된 암모니아 냉매증기를 정류하는 정류기내로 유입되는 암모니아 냉매증기에서 고농도의 암모니아 냉매증기를 얻기 위해서 암모니아 냉매증기와 응축수와의 열 및 물질전달 면적을 증가시키기 위한 수단을 구비하고, 상부로부터 떨어지는 응축수가 하단부의 열교환코일에 접촉하지 않도록 분리하는 수단을 구비함으로서 고농도의 암모니아 냉매증기를 형성하도록 하는데 목적이 있다.Accordingly, the present invention includes a means for increasing the heat and mass transfer area between the ammonia refrigerant vapor and condensate in order to obtain a high concentration of ammonia refrigerant vapor from the ammonia refrigerant vapor flowing into the rectifier to rectify the ammonia refrigerant vapor generated from the regenerator. It is an object of the present invention to provide a high concentration of ammonia refrigerant vapor by providing a means for separating the condensate falling from the top so as not to contact the heat exchange coil at the bottom.

본 발명의 암모니아 흡수식 냉난방기와 그 주변부의 구성은 제3도 내지 제5도에서와 같이 설명한다.The structure of the ammonia absorption type air conditioner of the present invention and its peripheral portion will be described as in FIGS. 3 to 5.

제3도 내지 제5도에서와 같이 재생기에서 생성된 암모니아 냉매증기를 정류하는 정류기(101)와, 상기 정류기(101)내로 유입되는 암모니아 냉매증기와 열교환이 이루어지도록 강용액이 유입되어 흐르도록 정류기(101)내에 형성된 열교환코일(104)과, 상기 열교환코일(104)사이에 형성되어 상부로부터 떨어지는 응축수를 하단부의 열교환코일과 접촉하지 않도록 응축수를 분리해 주는 베플 플레이트(102)와, 상기 정류기(101)내로 유입되는 암모니아 냉매증기와 응축수와의 열 및 물질전달 면적을 증가시켜주는 메쉬(103)로 구성한다.As shown in FIGS. 3 to 5, the rectifier 101 rectifies the ammonia refrigerant vapor generated in the regenerator, and the rectifier so that the strong solution flows in such a manner that heat exchange occurs with the ammonia refrigerant vapor introduced into the rectifier 101. A heat exchange coil 104 formed in the 101 and a baffle plate 102 formed between the heat exchange coil 104 and separating the condensed water so as not to contact the heat exchange coil of the lower end with the condensed water falling from the upper portion; 101 is composed of a mesh 103 for increasing the heat and mass transfer area between the ammonia refrigerant vapor and condensate flowing into the.

이와같이 구성된 본발명의 작용, 효과를 제3도 내지 제5도를 참조하여 상세히 설명하면 다음과 같다.The operation and effect of the present invention configured as described above will be described in detail with reference to FIGS. 3 to 5 below.

제3도 내지 제5도에서 도시한 바와같이 재생기에서 생성된 암모니아 냉매증기는 정류기(101)에서 정류된 후 응축기로 보낸다.As shown in FIGS. 3 to 5, the ammonia refrigerant vapor generated in the regenerator is rectified in the rectifier 101 and then sent to the condenser.

그러나 정류기(101)로 유입되는 암모니아 냉매증기에는 암모니아(NH3)와 물(H2O)의 비등점차가 크지않아 암모니아 냉매증기에 수분이 포함되어있다.However, the ammonia refrigerant vapor flowing into the rectifier 101 contains moisture because the boiling point difference between ammonia (NH 3 ) and water (H 2 O) is not large.

그래서 정류기(101)에서 고농도의 암모니아 냉매증기를 얻기 위해서는 수분을 응축시켜야하는데, 이때 수분을 응축시켜주는 매체로는 용액펌프에서 펌핑되어 정류기(101)로 보내지는 강용액을 사용한다.Therefore, in order to obtain a high concentration of ammonia refrigerant vapor in the rectifier 101, water must be condensed. At this time, a medium for condensing water uses a strong solution pumped from the solution pump and sent to the rectifier 101.

상기 강용액은 정류기(101)내에 감겨진 열교환코일(104)내를 흐르면서 암모니아 냉매증기와 열교환을 하면서 암모니아 냉매증기에 포함되어있는 수분을 응축시킨다.The steel solution flows through the heat exchange coil 104 wound in the rectifier 101 and condenses moisture contained in the ammonia refrigerant vapor while exchanging heat with the ammonia refrigerant vapor.

이때 응축된 응축수는 열교환코일(104)사이에 지그재그로 설치된 베플 플레이트(102)의 각단에서 하단부의 열교환코일과 접촉하지 않도록 분리 시켜준다.At this time, the condensed water condensed is separated from each end of the baffle plate 102 installed in a zigzag between the heat exchange coils 104 so as not to come into contact with the heat exchange coils at the lower end.

또한 열교환코일(104)사이에 다수개가 지그재그로 형성된 메쉬(103)는 암모니아 냉매증기와 응축수와의 직접 접촉에 의한 열 및 물질전달을 수행함으로써 보다 고농도의 암모니아 냉매증기를 얻는다.In addition, the mesh 103 formed of a plurality of zig-zags between the heat exchange coils 104 obtains a higher concentration of ammonia refrigerant vapor by performing heat and mass transfer by direct contact between the ammonia refrigerant vapor and condensate.

이상에서 상세히 설명한 바와같이 정류기로 유입되는 수분이 포함된 암모니아 냉매증기를 정류기내에서 응축수와 냉매증기와의 접촉면적을 증가시켜주고, 상단부에서 응축된 응축수를 하단부에 영향을 주지 않도록 분리하여 수분을 응축시키므로서 고농도의 암모니아 냉매증기를 얻을 수 있는 효과가 있다.As described in detail above, the ammonia refrigerant vapor containing water flowing into the rectifier increases the contact area between the condensate and the refrigerant vapor in the rectifier, and separates the condensed water condensed at the upper end so as not to affect the lower end. By condensation, it is possible to obtain a high concentration of ammonia refrigerant vapor.
