본 발명은 공냉형 흡수식 냉난방기에 관한 것으로서, 좀더 구체적으로는 공냉흡수기의 내부에 증발기를 설치하여 냉난방기를 콤팩트(Compact)화 시킬 수 있도록 한 것이다.The present invention relates to an air-cooled absorption type air conditioner, and more specifically, to install a evaporator inside the air-cooled absorber to compact the air conditioner (Compact).
종래의 공냉형 흡수식 냉난방기는 제1도와 같은 형태로서, 공냉흡수기(1)로부터 저온, 고온열교환기를 거쳐 보내어진 희흡수액(稀吸收液)(농도 57.4%, 134℃)을 가열시킴과 동시에 냉매증기를 방출하여 농출시키므로서 중간농도 흡수액(농도 60.4%, 154℃)으로 만드는 고온재생기(2) 및 상기 중간농도 흡수액을 냉각(88℃)시킴과 동시에 고온재생기에서 발생된 냉매증기(154℃)에 의해 재가열하여 냉매증기를 방출, 농축시켜 농흡수액(농도 63%, 92℃)으로 만들고, 이때 가열에 이용된 냉매증기를 냉매액으로 응축시키는 저온재생기(3)로 이루어진 재생기와, 상기 저온 재생기(3)에서 발생된 냉매증기를 냉매(물)에 의해 냉각시켜 응축(41℃)함과 동시에 저온 재생기에서 응축된 냉매액과 혼합시키는 공냉응축기(4)와, 상기 공냉응축기로부터 보내어진 냉매를 고진공(7mmHg)에서 냉수파이프(5) 표면에 뿌리므로서 파이프안에 흐르는 물로부터 중발잠열을 빼앗아 저온(4℃)에서 증발시키므로 냉수(7℃)를 만드는 증발기(6)와, 상기 증발기를 고진공(7mmHg)으로 유지하기위해 증발기에서 발생된 냉매증기를 저온재생기(3)로부터 저온열교환기(7)를 거쳐 보내어진 농흡수액(농도 63%, 50℃)에 흡수시켜 증발기를 고진공으로 유지하여 냉동능력을 지속시킴과 동시에 흡수력을 올리기 위해 냉각수로 농흡수액을 냉각시키고 상기 농흡수액은 냉매증기를 흡수하여 희석시켜 흡수액(농도 57.4%, 37℃)으로 만든다음 이를 고온재생기(2)로 보내는 공냉흡수기(1)로 구성되어 있다.The conventional air-cooled absorption type air conditioner is the same as that of FIG. 1, and heats the rare absorbent liquid (concentration 57.4%, 134 ° C) sent from the air-cooled absorber 1 through a low temperature and high temperature heat exchanger, and at the same time, coolant vapor. The high temperature regenerator (2) which makes the medium concentration absorbent liquid (concentration 60.4%, 154 ° C) and cools (88 ° C) the medium concentration absorbent liquid by releasing and concentrating it. Reheating to release and concentrate the refrigerant vapor to form a concentrated absorption liquid (concentration 63%, 92 ℃), wherein the regenerator consisting of a low-temperature regenerator (3) for condensing the refrigerant vapor used for heating into a refrigerant liquid, the low temperature regenerator ( 3) an air cooling condenser (4) which cools the refrigerant vapor generated in 3) with the refrigerant (water) to condense (41 DEG C) and mix with the refrigerant liquid condensed in the low temperature regenerator, and the refrigerant sent from the air cooling condenser (7 m mHg) takes the latent heat from the water flowing in the pipe by sprinkling it on the surface of the cold water pipe (5) and evaporates it at low temperature (4 ° C) to produce cold water (7 ° C) and the evaporator at high vacuum (7mmHg) The refrigerant vapor generated in the evaporator is absorbed into the concentrated absorbent liquid (concentration 63%, 50 ℃) sent from the low temperature regenerator (3) through the low temperature heat exchanger (7) to maintain the evaporator in a high vacuum to maintain the freezing capacity. In order to increase the absorbency at the same time, the concentrated absorbent liquid is cooled with cooling water, and the concentrated absorbent liquid absorbs and dilutes the refrigerant vapor to make the absorbent liquid (concentration 57.4%, 37 ° C) and sends it to the high temperature regenerator (2). Consists of
상기 증발기(6) 내부는 약 0.1Torr의 대기압이하로 유지되어 있고 그 내부에는 물이 흐르는 파이프(5)가 설치되어 있다.The inside of the evaporator 6 is maintained below the atmospheric pressure of about 0.1 Torr and the pipe 5 through which water flows is installed.
따라서 냉매펌프(8)의 동작으로 파이프(5) 상부에서 파이프(5) 표면에 냉매(물)을 뿌리면 약 4℃에서 냉매가 증발된다.Therefore, when the refrigerant (water) is sprayed on the surface of the pipe 5 in the upper part of the pipe 5 by the operation of the refrigerant pump 8, the refrigerant evaporates at about 4 ° C.
이때 냉매가 증발하면서 파이프(5)내의 물로부터 증발잠열을 빼앗기 때문에 물은 약 7℃의 냉수가 된다.At this time, since the refrigerant evaporates the latent heat of evaporation from the water in the pipe 5 while the refrigerant evaporates, the water becomes cold water of about 7 ° C.
상기 냉수를 실내로 순환시키면서 냉방을 하게 된다.Cooling is performed while circulating the cold water into the room.
한편, 증발기(6)에서 증발된 냉매증기는 닥트(9)를 통해 공냉흡수기(1)로 유입되는데, 상기 공냉흡수기(1)의 상부에서는 약 60% 정도의 진한 취화리듐(LiBr)수용액이 스프레이(Spray)된다.On the other hand, the refrigerant vapor evaporated from the evaporator (6) is introduced into the air-cooled absorber (1) through the duct (9), about 60% of the concentrated lithium briquette (LiBr) aqueous solution is sprayed on top of the air-cooled absorber (1) (Spray).
따라서 흡수성이 강한 취화리듐 수용액은 냉매증기를 흡수하여 약 58% 정도의 묽은 취화리듐 수용액이 된다.Therefore, the absorbent lithium briquette aqueous solution absorbs the refrigerant vapor and becomes about 58% of the thin lithium briquette aqueous solution.
상기한 바와 같은 흡수작용시에는 발열 반응이 일어나기 때문에 발생되는 열을 지속적으로 냉각시켜 주어야 되는데, 이때 매체가 물인 경우에는 수냉식이고 공기인 경우에는 공냉식이 된다.During the absorption, as described above, an exothermic reaction occurs, and thus the heat generated must be continuously cooled. In this case, when the medium is water, the water is cooled and the air is cooled by air.
상기 공냉흡수기(1)에서 농도가 묽어진 취화리듐 수용액은 냉매와 흡수재인 취화리듐을 분리하기 위해 재생기로 보내어진다.In the air-cooled absorber (1), the diluted aqueous solution of lithium halide is sent to the regenerator to separate the refrigerant and the absorbent lithium halide.
이는 가스등의 연소열을 이용하여 분리시키는데, 그 원리는 냉매인 물과 흡수액인 취화리듐수용액의 비등점 차이를 이용한다.This is separated by the use of combustion heat such as gas, the principle of which uses the difference in boiling point between the water of the refrigerant and the aqueous solution of lithium embrittlement of the absorbent liquid.
약 58%로 묽어진 취화리듐 수용액은 연소열에 의해 약 90∼100℃ 부근에서 비등을 시작하여 냉매가 증기로 되어 취화리듐과 분리된다.Aqueous dilute aqueous solution of about 58% starts boiling at about 90 to 100 DEG C by the heat of combustion, and the refrigerant becomes vapor and is separated from the lithium embrittlement.
증기가 발생되면 취화리듐은 다시 60% 정도의 진한 용액이 되어 공냉흡수기(1)로 보내어지게 되므로 싸이클(Cycle)을 순환하게 된다.When steam is generated, the lithium embrittlement becomes a thick solution of about 60% and is sent to the air-cooling absorber 1, thereby circulating the cycle.
한편 고온재생기(2)에서 발생된 증기를 증발기(6)에서 다시 이용 하기 위해서는 액화시켜야 된다.On the other hand, the steam generated in the high temperature regenerator 2 has to be liquefied in order to use it again in the evaporator 6.
따라서 증기 배관(10)을 따라 이동하여 저온재생기(3)내에 있던 용액(11)을 가열시키면서 액냉매가 되어 공냉응축기(4)로 보내어지게 되고, 저온재생기(3)내에 있던 냉매는 이때 가열되어 닥트(12)를 통해 공냉 응축기(4)로 보내어질때 팬(13)에 의해 응축되어 증발기(6)로 보내어지게 되므로 순환 싸이클을 이루게 된다.Therefore, while moving along the steam pipe 10 to heat the solution 11 in the low temperature regenerator 3, it becomes a liquid refrigerant and is sent to the air-cooled condenser 4, the refrigerant in the low temperature regenerator 3 is heated at this time When sent to the air-cooled condenser (4) through the duct (12) is condensed by the fan 13 is sent to the evaporator (6) to form a cycle.
그러나 이러한 종래의 흡수식 냉난방기는 증발기(6)와 공냉흡수기(1)가 분리형성되어 닥트(9)로 연결되어 있어 소형화가 어렵게 되었음은 물론 증발기(6)에서 발생된 냉매증기가 닥트(9)를 통해 공냉흡수기까지 이동하도록 되어 있으므로 열손실이 많게 되고, 이에따라 열효율이 저하되는 문제점이 있었다.However, such a conventional absorption air-conditioner is separated from the evaporator 6 and the air-cooled absorber 1 and is connected to the duct 9, which makes it difficult to miniaturize the refrigerant vapor. Since it is intended to move to the air-cooled absorber through the heat loss is a lot, there was a problem that the thermal efficiency is lowered accordingly.
본 발명은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로서, 공냉흡수기와 증발기를 일체화하여 냉난방기를 콤팩트화함과 동시에 증발기에서 발생된 증기냉매를 빠른 시간내에 흡수하도록 하므로서 증발 효율을 향상시킬 수 있도록 하는데 그 목적이 있다. 상기 목적을 달성하기 위한 본 발명에 따르면, 밀폐된 공냉식 흡수기내에 코일형상으로 권회되게 설치되어 순환펌프에 의해 물을 순환시키는 증발기와, 상기 증발기의 상부에 설치되어 냉매를 증발기 표면으로 공급하는 냉매탱크와, 상기 냉매탱크의 하부에 위치되게 공냉식 흡수기의 상부에 설치되어 냉매증기를 흡수하는 용액을 공냉식흡수기의 내면으로 공급하는 용액탱크와, 상기 증발기 및 공냉식 흡수기 사이에 설치되어 냉매 및 용액이 혼입되는 것을 방지하는 일리미네이터와, 상기 혼입된 용액을 재생기로 보내기 위해 공냉식 흡수기와 재생기 사이에 연결된 파이프로 구성된 증발기가 내장된 일체형 공냉흡수기가 제공된다.The present invention has been made to solve such a problem in the prior art, by integrating the air-cooling absorber and the evaporator to compact the air conditioner and at the same time to absorb the vapor refrigerant generated in the evaporator to improve the evaporation efficiency to be quickly The purpose is. According to the present invention for achieving the above object, an evaporator installed in a coiled form in a sealed air-cooled absorber to circulate water by a circulation pump, and a refrigerant installed on the evaporator to supply the refrigerant to the evaporator surface. A solution tank is installed above the air-cooled absorber so as to be positioned below the refrigerant tank to supply a solution that absorbs refrigerant vapor to the inner surface of the air-cooled absorber, and is installed between the evaporator and the air-cooled absorber to mix the refrigerant and the solution. There is provided an integrated air cooling absorber with a built-in eliminator and an evaporator consisting of a pipe connected between the air cooled absorber and the regenerator to direct the entrained solution to the regenerator.
이하, 본 발명을 일실시예로 도시한 첨부된 도면 제2도를 참고로하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIG. 2 of the accompanying drawings.
첨부도면 제2도는 본 발명의 요부를 나타낸 종단면도로써, 본 발명에서 고온재생기 및 저온재생기 그리고 공냉응축기는 종래 냉난방기와 동일하므로 되시를 생략하였다.2 is a longitudinal cross-sectional view showing the main part of the present invention, and since the high temperature regenerator, the low temperature regenerator, and the air-cooled condenser are the same as those of the conventional air conditioner, the dashes are omitted.
밀폐된 공냉식 흡수기(21)내에 코일형상으로 권회된 즈발기(22)가 설치되어있어 순환펌프(23)의 동작에 따라 물을 하부에서 상부로 순환시키도록 되어 있고 상기 증발기(22)의 상부외측에는 증발기(22)의 표면으로 냉매(24)를 공급하기위한 냉매탱크(25)가 설치되어 있다.The enclosed air-cooled absorber 21 is provided with a coil-shaped coil swivel 22 to circulate water from the lower part to the upper part according to the operation of the circulation pump 23, and the upper outer side of the evaporator 22. The refrigerant tank 25 for supplying the refrigerant 24 to the surface of the evaporator 22 is installed.
그리고 상기 냉매탱크(25)의 하부에 위치되는 공냉식흡수기(21)의 상부에는 증발기(22)로부터 잠열을 빼앗을때 발생되는 냉매증기를 흡수하기 위한 용액(26)을 공냉식흡수기(21)의 내면으로 공급하는 용액탱크(27)가 설치되어 있고 상기 증발기(22)과 공냉식흡수기(21) 사이에는 냉매(24)와 용액(26)이 혼입되는 것을 방지하기 위한 일리미네이터(Elimi-nator)(28)가 설치되어 있으며 상기 공냉식흡수기(21)와 재생기(도시는 생략함)사이에는 혼입된 냉매를 재생기로 보내 분리시키기 위해 파이프(29)가 연결되어 있다.In addition, an upper portion of the air-cooled absorber 21 positioned below the refrigerant tank 25 has a solution 26 for absorbing refrigerant vapor generated when the latent heat is taken from the evaporator 22 toward the inner surface of the air-cooled absorber 21. A solution tank 27 for supplying is installed, and an eliminator 28 is provided between the evaporator 22 and the air-cooled absorber 21 to prevent the refrigerant 24 and the solution 26 from mixing. It is installed and the pipe 29 is connected between the air-cooled absorber 21 and the regenerator (not shown) to send the mixed refrigerant to the regenerator.
이때 파이프(29)상에는 용액을 강제 이송시키기 위한 펌프(30)가 설치된다. 또한 냉매(24)와 용액(26)의 혼입을 방지하기위해 설치되는 일리미네이터(28)는 단면이 "∧"형상으로 권회되어 있어 냉매증기가 이들 틈새를 통해 용액측으로 이동하도록 되어 있다.At this time, a pump 30 for forcibly transferring the solution is installed on the pipe 29. In addition, the eliminator 28 provided to prevent mixing of the refrigerant 24 and the solution 26 is wound in a cross-section of "∧" so that the refrigerant vapor moves to the solution side through these gaps.
그리고 상기 공냉식흡수기(21)의 외주면에는 방열핀(31)이 형성되어 있어 용액이 냉매증기를 흡수할때 발생되는 열을 팬(32)에 의해 발생된 바람으로 방열핀(31)을 통해 빠른 시간내에 냉각시키도록 되어 있다.In addition, the heat dissipation fins 31 are formed on the outer circumferential surface of the air-cooled absorber 21, and the heat generated when the solution absorbs the refrigerant vapor is cooled by the heat dissipation fins 31 by the wind generated by the fan 32. It is supposed to be.
이와 같이 구성된 본 발명의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
먼저 순환펌프(23)를 동작시켜 공냉식흡수기(21)의 내부에 삽입된 증발기(22)로 물(약 12℃)을 공급하면서 냉매탱크(25)로부터 증발기(22) 표면으로 냉매(24)를 흘려보내면 공냉식흡수기(21)의 내부가 약 6∼7mmHg의 압력이기 때문에 약 5℃에서 냉매의 증발이 일어난다.First, the circulation pump 23 is operated to supply water (approximately 12 ° C.) to the evaporator 22 inserted into the air-cooled absorber 21, thereby transferring the refrigerant 24 from the refrigerant tank 25 to the surface of the evaporator 22. If it flows, since the inside of the air-cooled absorber 21 is a pressure of about 6-7 mmHg, the refrigerant evaporates at about 5 ° C.
이에따라 증발기(22) 내부의 물로부터 증발잠열을 빼앗기 때문에 증발기(22) 내부를 흐르던 물은 12℃에서 7℃로 냉각됨과 동시에 냉각된 물이 실내로 이동되어 실내를 냉방하게 된다.Accordingly, since the latent heat of evaporation is taken from the water inside the evaporator 22, the water flowing in the evaporator 22 is cooled from 12 ° C to 7 ° C and the cooled water is moved to the room to cool the room.
이와 같이 물로부터 증발잠열을 빼앗을때 발생된 냉매증기는 일리미네이터(28)의 사이를 통과하여 공냉식 흡수기(21)의 냉면측으로 이동된다.Thus, the refrigerant vapor generated when the latent heat of evaporation is taken from the water passes through the eliminator 28 and is moved to the cold surface side of the air-cooled absorber 21.
이때 용액탱크(27)로부터 흡수성이 매우높은 진한 용액(26)이 흘러내리면서 냉매증기를 흡수한 다음 묽은 용액으로되어 공냉식흡수기(21)의 하부에 고이게 되는데, 냉매(24)와 용액(26)은 일리미네이터(28)가 "∧" 형상의 단면을 갖이고 있어 이들이 상호 혼입되지 않게된다.At this time, the concentrated solution 26, which is very absorbent, flows down from the solution tank 27, absorbs the refrigerant vapor, becomes a dilute solution, and accumulates in the lower part of the air-cooled absorber 21. The refrigerant 24 and the solution 26 The silver eliminator 28 has a "의" shaped cross section so that they are not mixed with each other.
상기한 바와 같이 용액(26)이 냉매증기를 흡수랄때에는 열이 발생되는데, 이때 발생된 열은 공냉식흡수기(21)의 외측으로 형성된 방열핀(31)을 통해 외부로 방열되며 이는 팬(32)의 회전에 의해 냉각된다.As described above, heat is generated when the solution 26 absorbs the refrigerant vapor, and the generated heat is radiated to the outside through the heat dissipation fin 31 formed outside of the air-cooled absorber 21, which is used in the fan 32. Cooled by rotation.
한편 공냉식흡수기(21)의 하부에 고인 묽은 용액은 펌프(30)의 구동으로 공냉식흡수기(21)와 재생기 사이에 연결된 파이프(29)를 통해 이송되어 용액과 냉매로 분리되어 공냉식흡수기(21)에 설치된 냉매탱크(25)와 용액탱크(27)로 공급되므로 싸이클(Cycle)을 이루게 되는 것이다.On the other hand, the dilute solution accumulated in the lower part of the air-cooled absorber 21 is transferred through the pipe 29 connected between the air-cooled absorber 21 and the regenerator by the driving of the pump 30 to be separated into a solution and a refrigerant to the air-cooled absorber 21. Since it is supplied to the installed refrigerant tank 25 and the solution tank 27 is to achieve a cycle (Cycle).
이상에서와 같이 본 발명은 공냉식흡수기(21)의 내부에 증발기(22)를 설치하도록 되어 있으므로 냉난방기를 콤팩트화시킬 수 있게 됨은 물론 증발기(22)에서 발생된 냉매증기가 일리미네이터(28)를 통해 공냉식흡수기(21)에서 용액에 의해 바로 흡수되므로 증발효율을 향상시키게 되는 효과를 가지게 된다.As described above, in the present invention, since the evaporator 22 is installed inside the air-cooled absorber 21, the air conditioner can be made compact, as well as the refrigerant vapor generated in the evaporator 22 is air-cooled through the eliminator 28. Since it is directly absorbed by the solution in the absorber 21 has the effect of improving the evaporation efficiency.
