본 발명은 흡착식 냉동기용 흡착탑에 관한 것으로, 특히 냉각수 및 온수의 난류성을 좋게 하고, 균일한 열전달 성능을 확보하며, 흡착제의 밀봉작업이 용이하고, 냉매증기가 원활하게 흐를 수 있도록 한 흡착식 냉동기용 적층형 흡착탑에 관한 것이다.The present invention relates to an adsorption tower for adsorption freezers, in particular, to improve the turbulence of cooling water and hot water, to ensure uniform heat transfer performance, to facilitate the sealing operation of the adsorbent, and to allow the refrigerant vapor to flow smoothly. It relates to an adsorption tower.

일반적으로 흡착식 냉동기는 흡수식 냉동기와 더불어 비프레온화와 폐열이라는 관점에서 주목을 받고 있는 냉동방식이다. 냉동원리는 흡수식과 비슷한데, 흡수기 대신 흡착탑이 있으며, 이 흡착탑에는 흡착제가 고정되어 있고 냉매만 순환하게 되어 있다.In general, the adsorption freezer is a freezing method that has attracted attention in terms of non-freonization and waste heat in addition to the absorption freezer. The freezing principle is similar to the absorption type, in which there is an adsorption tower instead of an adsorber, in which an adsorbent is fixed and only a refrigerant is circulated.

일예로 흡착제로 실리카겔을, 냉매로서 물을 작동매체로 하는 흡착식 냉동기는 각종 발전소 및 공장에서 버려지는 폐열(60∼95℃)을 재활용하여 실내의 냉방을 행할 수 있어 환경친화적이며, 미이용에너지 활용 및 국가 에너지절약 차원에서 활 발한 연구가 요구되어 진다.For example, the adsorption-type freezer, which uses silica gel as an adsorbent and water as a working medium, can recycle the waste heat (60 to 95 ° C) discarded in various power plants and factories, thereby cooling the room and being environmentally friendly. Active research is needed at the national energy conservation level.

그러나 흡착식 냉동기는 아직까지 시스템의 효율이 낮아서 국내에서는 전혀 보급되지 못하고 있는 실정이다. 흡착식 냉동기의 구성요소는 2개의 흡착탑, 증발기, 응축기 등으로 구성되어 있으며 이 중에서 흡착탑은 흡착식 냉동기 중에서 가장 많은 체적을 차지하고 성능에 가장 큰 영향을 미치는 요소이다.However, the adsorption chiller has not yet been widely distributed in Korea due to the low efficiency of the system. The adsorption chiller consists of two adsorption towers, an evaporator, and a condenser. Among them, the adsorption tower occupies the largest volume and is the most influential factor in performance.

흡착식 냉동기의 원리를 도 5에서 간단히 살펴보면, 2개의 흡착탑(HEX1,HEX2), 증발기(EVA), 응축기(COND) 등으로 구성되어 있으며, 4개의 작동모드(MODE A~D)를 통하여 밸브의 조작과 작동시간의 조작으로 증발기에서 냉수(일반적으로 7℃)를 얻어내어 실내의 냉방을 할 수 있는 환경친화적인 냉방시스템이다. 5, the principle of the adsorption-type freezer is composed of two adsorption towers (HEX1, HEX2), evaporator (EVA), condenser (COND), etc., the operation of the valve through four operating modes (MODE A ~ D) It is an environmentally friendly cooling system that can cool the room by obtaining cold water (generally 7 ℃) from the evaporator by the operation of overtime.

즉, 냉매가 증발기(EVA)에 분사되어 증발이 일어나고, 이때의 증발잠열에 의해 냉수(Chilled water)가 얻어진다. 증발된 냉매증기는 제1흡착탑(HEX1)에 흡착되고 이때 냉각수(Cooling water) 흡착열을 제거하여 주는 흡착사이클을 이루게 된다.That is, the refrigerant is injected into the evaporator (EVA) to cause evaporation, and chilled water is obtained by the latent heat of evaporation at this time. The evaporated refrigerant vapor is adsorbed to the first adsorption tower (HEX1) to form an adsorption cycle to remove the cooling water (heating) adsorption heat.

이때 제2흡착탑(HEX2)에서는 열매체로 가열되어 냉매증기가 이탈되는 탈착이 이루어져 응축기(COND)로 공급되고 냉각수에 의해 응축되어 다시 증발기로 공급된다.At this time, the second adsorption tower (HEX2) is heated by a heat medium to desorb the refrigerant vapor is removed is supplied to the condenser (COND), condensed by the cooling water is supplied to the evaporator again.

여기서 구동원으로 사용되는 온수(Hot water)는 발전소 및 각종 공장에서 버려지는 폐열을 활용할 수가 있으며 전기 및 가스를 전혀 사용하지 않고 냉매로서 물을 사용하므로 이산화탄소 등의 배출염려가 전혀 없다.Here, hot water used as a driving source can utilize waste heat discarded in power plants and various factories, and there is no fear of emission of carbon dioxide since it uses water as a refrigerant without using electricity and gas at all.

한편, 흡착식 냉동기의 선행 기술들을 검토해 보면 흡착탑으로 사용되고 있 는 열교환기의 형상으로 도 1과 같은 Shell and tube type, 도 2와 같은 평 파이프 타입(Flat-pipe type), 도 3과 같은 평 핀 타입(Plate-fin type), 도 4와 같은 선회 플레이트 타입(Spiral plate type)이 적용되고 있다. Meanwhile, if the prior art of the adsorption type refrigerator is examined, the shape of the heat exchanger used as the adsorption tower may be a shell and tube type as shown in FIG. 1, a flat-pipe type as shown in FIG. 2, and a flat fin type as shown in FIG. 3. (Plate-fin type), the spiral plate type as shown in Figure 4 is applied.

그러나 이러한 형상과 구조들은 냉동공조분야에서 다양하게 사용하고 있어 구조가 간단하고 값이 싸다는 장점이 있으나, 흡착제와 열전달 튜브 핀 사이의 열저항이 대단히 크고, 냉매증기의 유로확보가 곤란하여 시스템의 효율을 올리는데 한계가 있다.However, these shapes and structures are variously used in the refrigeration and air-conditioning field. However, the structure and structure are simple and inexpensive. However, the heat resistance between the adsorbent and the heat transfer tube fin is very large, and the flow path of the refrigerant vapor is difficult to secure. There is a limit to increase the efficiency.

따라서 본 발명은 상기와 같은 제반적인 사정을 감안하여 창출된 것으로, 냉각수 및 온수의 난류성을 좋게 하고, 균일한 열전달 성능을 확보하며, 흡착제의 밀봉작업이 용이하고, 냉매증기가 원활하게 흐를 수 있도록 한 흡착식 냉동기용 적층형 흡착탑을 제공함에 그 목적이 있다.Therefore, the present invention was created in view of the above-mentioned circumstances, and improves the turbulence of cooling water and hot water, ensures uniform heat transfer performance, facilitates sealing of the adsorbent, and allows the refrigerant vapor to flow smoothly.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1에 흡착식 냉동기에 사용되는 적층형 흡착탑(10)이 예시되어 있다.A stacked adsorption tower 10 for use in an adsorption freezer is illustrated in FIG. 1.

도면 부호 '20','30'은 흡착탑(10)에 포함된 것으로 상호 마주보도록 대향되게 배치되고 각기 열유체 입,출구(20a,30a)를 갖는 한쌍의 '헤드파이프'이다.Reference numerals '20' and '30' are included in the adsorption tower 10 and are disposed to face each other, and are a pair of 'head pipes' having thermal fluid inlets and outlets 20a and 30a, respectively.

상기 한쌍의 헤드파이프(20,30)는 금속재로서 각기 열유체 입,출구(20a,30a) 와 연통되어 나란하게 분기된 다수의 분배관(21,31)이 구비되고, 각 분배관(21,31)에는 다공튜브(40)와 접속되기 위해 도 8과 같이 일정 간격마다 접속구멍(21a,31a)이 형성되어 있다.The pair of head pipes 20 and 30 are made of metal and are provided with a plurality of distribution pipes 21 and 31 branched side by side in communication with the thermal fluid inlets and outlets 20a and 30a, respectively. 31, connection holes 21a and 31a are formed at regular intervals as shown in FIG. 8 to be connected to the porous tube 40. As shown in FIG.

상기 한쌍의 헤드파이프(20,30) 사이에는 도 6 및 도 7과 같이 일정 간격을 두고 격자 형태로 다공튜브(40)가 배치되어 있다.Between the pair of head pipes 20 and 30, the porous tube 40 is disposed in a lattice form at regular intervals as shown in FIGS.

상기 다공튜브(40)는 일측 헤드파이프(20)로부터 유입된 열유체를 타측 헤드파이프(30)로 흘려보내기 위해 다수의 열유체통로(41)가 형성되어 있다. 상기 열유체통로(41)는 본 실시예에서 전도를 극대화하기 위해 사각단면 형태를 가지고 병열로 촘촘하게 형성되어 있다.The porous tube 40 has a plurality of heat fluid passages 41 are formed in order to flow the heat fluid introduced from one head pipe 20 to the other head pipe 30. The heat fluid passage 41 has a square cross-sectional shape and is densely formed in parallel to maximize conduction in the present embodiment.

본 발명에서 열유체통로(41)의 단면 구성은 예시된 것에 한정되는 것은 아니다.In the present invention, the cross-sectional configuration of the heat fluid passage 41 is not limited to the one illustrated.

상기 다공튜브(40)들의 이웃한 공간에는 상기 열유체통로(41)를 흐르는 열유체와의 열교환을 이루기 위한 열교환수단으로 알루미늄핀(50)이 배치되어 있다.In the adjacent space of the porous tubes 40, the aluminum fin 50 is arranged as a heat exchange means for heat exchange with the heat fluid flowing through the heat fluid passage 41.

상기 알루미늄핀(50)은 얇은 박판으로 제작된 파형 형태로서 상기 다공튜브(40)의 대향하는 벽면에 부착되어 있다. 여기서 파형이란 지그재그 형태로서 예로 S자 또는 Z자 형태로 나타날 수 있다.The aluminum fin 50 is a wave form made of a thin thin plate is attached to the opposing wall surface of the porous tube 40. Here, the waveform may be in a zigzag form, for example, in the form of S or Z.

상기 알루미늄핀(50)의 표면에는 바람직하게 도 9와 같이 공기 흐름의 경계층을 깨뜨리면서 공기의 흐름을 방해하여 마찰계수를 높여주는 다수의 루버(51)가 더 형성될 수 있으며, 도 10에서와 같이 상기 루버(51)가 아닌 옵셋스트립핀(52)으로도 형성될 수 있음은 물론이다.9, a plurality of louvers 51 may be further formed on the surface of the aluminum fin 50 to increase the friction coefficient by interrupting the flow of air while breaking the boundary layer of the air flow as shown in FIG. 9. Likewise, it may be formed of the offset strip pin 52 instead of the louver 51.

이와 같이 구성된 적층형 흡착탑(10)은 다공튜브(40)들의 사이사이에 배치된 알루미늄핀(50)의 틈새에 흡착제(미도시 됨)가 충진된다.The stacked adsorption tower 10 configured as described above is filled with an adsorbent (not shown) in the gap between the aluminum fins 50 disposed between the porous tubes 40.

본 실시예에서 흡착제는 저온폐열을 회수하여 사용할 수 있도록 80℃ 정도의 열원만 있으면 탈착이 가능한 실리카 겔(Silica Gel)을 사용하였다. 본 발명은 이에 한정되는 것은 탈착온도에 따라 제올라이트, 활성탄 등을 적용할 수 있음은 물론이다.In this embodiment, the adsorbent used a silica gel that can be desorbed if only a heat source of about 80 ° C. was used to recover the low temperature waste heat. The present invention is limited to this, of course, can be applied to zeolite, activated carbon, etc. according to the desorption temperature.

이와 같이 구성된 흡착식 냉동기용 흡착탑(10)의 작용을 설명한다.The operation of the adsorption tower 10 for the adsorption-type freezer configured as described above will be described.

본 발명의 적층형 흡착탑(10)을 적용한 흡착 및 탈착 사이클에 대한 설명은 도 5에 도시한 사이클 모드를 참조한다.Description of the adsorption and desorption cycles to which the stacked adsorption tower 10 of the present invention is applied refers to the cycle mode shown in FIG. 5.

<흡착 사이클시><At adsorption cycle>

먼저, 도 5와 같이 증발기(EVA) 내에 냉매(물)를 분사하면 증발잠열에 의해 냉수(Chilled water)가 얻어지고, 증발된 냉매증기는 2개의 흡착탑(10) 중 어느 하나의 다공튜브(40)의 사이사이에 충진된 흡착제에 흡착되어 증발이 계속 진행된다.First, when the refrigerant (water) is injected into the evaporator (EVA) as shown in FIG. 5, chilled water is obtained by latent heat of evaporation, and the evaporated refrigerant vapor is the porous tube 40 of any one of the two adsorption towers 10. Adsorption is carried out by adsorbent filled between) and evaporation continues.

이때 해당 흡착탑(10)에서는 냉각수가 하부측 헤드파이프(20)의 열유체 입구(20a)를 통하여 다수의 분배관(21)으로 공급된다. 분배관(21)으로 유입된 냉각수는 다공튜브(40)의 다수의 열유체통로(41)를 경유한 후 상부측 헤드파이프(30)의 분배관(31)을 거쳐 열유체 출구(30a)로 배출된다.At this time, the adsorption column 10 is supplied to the plurality of distribution pipes 21 through the heat fluid inlet 20a of the lower head pipe 20. The coolant introduced into the distribution pipe 21 passes through the plurality of thermal fluid passages 41 of the porous tube 40 and then through the distribution pipe 31 of the upper head pipe 30 to the thermal fluid outlet 30a. Discharged.

이때 다공튜브(40)의 벽면에 접촉되어 있는 알루미늄 핀(50)에서 열전도가 일어나 흡착열을 제거하여 줌으로써, 다공튜브(40)의 사이사이 즉 알루미늄 핀(50)에 충진된 흡착제의 흡착이 활발하게 이루어진다.At this time, heat conduction occurs in the aluminum fin 50 in contact with the wall of the porous tube 40 to remove the heat of adsorption, thereby actively adsorbing the adsorbent filled between the porous tubes 40, that is, the aluminum fin 50. Is done.

이와 같이 흡착이 계속 진행되어 평형상태가 되면 흡착은 더 이상 진행되지 않으므로 해당 흡착기(10)는 탈착 사이클로 전환한다.As the adsorption proceeds in an equilibrium state as described above, the adsorption no longer proceeds, so that the adsorber 10 switches to a desorption cycle.

<탈착 사이클시><At the time of desorption cycle>

탈착은 흡착이 완료된 흡착탑(10)을 열매체로 가열하여 냉매증기를 이탈시킴으로써 이루어진다. Desorption is performed by heating the adsorption tower 10 where adsorption is completed with a heat medium to leave the refrigerant vapor.

본 실시예에서는 각종 발전소 및 공장에서 버려지는 폐열을 열매체로 이용한다.In this embodiment, waste heat discarded in various power plants and factories is used as a heat medium.

알루미늄핀(50) 내에 충진된 흡착제에서 탈착된 냉매증기는 응축기(COND)로 보내지고, 응축기(COND)에서 냉각수에 의해 응축되어 다시 증발기(EVA)로 공급된다.The refrigerant vapor desorbed from the adsorbent packed in the aluminum fin 50 is sent to the condenser COND, condensed by the cooling water in the condenser COND, and supplied to the evaporator EVA again.
