본 발명은 흡수식 냉온수기에 관한 것으로서, 특히 흡수기 내에서 자유낙하하는 흡수액의 쏠림현상을 방지하여 열교환의 효율을 향상시킬 수 있게 구성한 것이다.The present invention relates to an absorption type cold and hot water heater, and in particular, is configured to improve the efficiency of heat exchange by preventing the dropping of the absorbing liquid falling freely in the absorber.

도면에서, 도 1은 종래의 기술에 따른 흡수식 냉온수기의 개념도이고, 도 2는 용액냉각흡수기가 장착된 흡수식 냉온수기의 개념도이며, 도 3은 트레이 아래에 위치한 전열관의 젖음상태를 나타낸 개략도이다.1 is a conceptual diagram of an absorption chiller according to the prior art, Figure 2 is a conceptual diagram of an absorption chiller equipped with a solution cooling absorber, Figure 3 is a schematic diagram showing the wet state of the heat transfer tube located under the tray.

도 1에 도시된 바와 같이, 흡수식 냉온수기(1)는 LPG, LNG 등과 같은 가스를 열원으로 사용하여 흡수액 냉매로 이루어진 냉방사이클을 운전하는 것으로서, 전기를 에너지원으로 사용하는 냉온수기와는 다르게 일차적으로 열에너지를 이용하기 때문에 하절기에 과다한 전력부하를 해소하고, 또한 폐열을 이용한 열병합시스템의 활용 등과 같이 다양한 장점을 가지고 있다.As shown in FIG. 1, the absorption type cold water heater 1 operates a cooling cycle composed of an absorbent refrigerant using gas such as LPG and LNG as a heat source, and is primarily thermal energy unlike a cold or hot water system using electricity as an energy source. Because of this, there is a variety of advantages, such as eliminating excessive power load in the summer, the utilization of cogeneration system using waste heat.

이와 같은 흡수식 냉온수기의 구성을 살펴보면, 흡수식 냉온수기를 구성하는 증발기흡수기동체(30)는 증발기(31) 및 흡수기(32)를 함께 구비하며, 고온재생기(10)에는 버너(11)가 수용된다.Looking at the configuration of the absorption chiller, the evaporator absorber 30 constituting the absorption chiller is provided with an evaporator 31 and the absorber 32, the burner 11 is accommodated in the high temperature regenerator (10).

상기 흡수기(32)에서 상기 고온재생기(10)로 연장된 희용액배관(83)에는 흡수액펌프(72), 저온열교환기(40) 및 고온열교환기(50)가 순서대로 설치된다. 그리고 저온재생기응축기동체(20)는 저온재생기(23)와 응축기(21)가 함께 구비되어 있다.An absorbent liquid pump 72, a low temperature heat exchanger 40, and a high temperature heat exchanger 50 are sequentially installed in the rare solution pipe 83 extending from the absorber 32 to the high temperature regenerator 10. The low temperature regenerator condenser body 20 includes a low temperature regenerator 23 and a condenser 21 together.

그리고 상기 고온재생기(10)에서 저온재생기(23)로 연장된 관은 냉매증기관(81)이고, 상기 응축기(21)에서 상기 증발기(31)로 연장된 관은 냉매액 유하관(82)이며, 상기 흡수기(32)로 유입되는 관은 냉각수관(86)이다. In addition, the tube extending from the high temperature regenerator 10 to the low temperature regenerator 23 is a refrigerant steam engine 81, and the tube extending from the condenser 21 to the evaporator 31 is a refrigerant liquid downflow tube 82. The pipe flowing into the absorber 32 is a cooling water pipe (86).

상기와 같이 구성한 흡수식 냉온수기의 운전 시, 상기 고온재생기(10)의 버너(11)에서 연료가스(LPG, LNG)가 연소하면, 상기 흡수기(32)에서 흘러온 리튬브로마이드 수용액(계면활성제 포함)과 같은 희용액이 가열되어 비등하고, 냉매증기가 희용액에서 분리된다. 이와 같이 가열되면서 희용액은 분리되어 농축되면서 농도가 보다 진한 중간용액으로 된다. 한편 냉매증기는 냉매증기관(81)을 따라 이동하여 상기 저온재생기(23)로 유입된다. 그리고 상기 고온재생기(10)에서 저온재생기(23)로 들어온 중간용액은 저온재생기(23)에서 가열되어 냉매액으로 응축되고, 응축된 냉매액은 상기 응축기(21)로 흐른다. 상기 응축기(21)에서는 상기 저온재생기(23)로부터 흘러들어온 냉매증기가 응축하여, 냉매액과 함께 상기 증발기(31)로 이동한다.During operation of the absorption type cold and hot water heater configured as described above, if the fuel gas (LPG, LNG) is burned in the burner 11 of the high temperature regenerator 10, such as lithium bromide aqueous solution (including the surfactant) flowing from the absorber 32 The rare solution is heated to boil and the refrigerant vapor is separated from the rare solution. As the heating is performed, the rare solution is separated and concentrated to give a thicker intermediate solution. Meanwhile, the refrigerant vapor moves along the refrigerant vapor engine 81 and flows into the low temperature regenerator 23. The intermediate solution entering the low temperature regenerator 23 from the high temperature regenerator 10 is heated in the low temperature regenerator 23 to condense into the refrigerant liquid, and the condensed refrigerant liquid flows into the condenser 21. In the condenser 21, the refrigerant vapor flowing from the low temperature regenerator 23 condenses and moves to the evaporator 31 together with the refrigerant liquid.

상기 증발기(31)에서는 냉매펌프(71)의 작동에 의해서 냉매액이 산포된다. 그리고 상기 증발기(31)에서 기화한 냉매증기는 상기 흡수기(32)로 흘러 산포된 흡수액에 흡수된다. 한편, 상기 고온재생기(10)에서 냉매증기가 분리되어 농도가 상 승한 중간용액은 중간용액배관(84), 고온열교환기(50)를 거쳐서 상기 저온재생기(23)로 흐른다.In the evaporator 31, the refrigerant liquid is dispersed by the operation of the refrigerant pump 71. The refrigerant vapor vaporized by the evaporator 31 flows into the absorber 32 and is absorbed by the scattered absorbent liquid. Meanwhile, the intermediate solution in which the refrigerant vapor is separated from the high temperature regenerator 10 and the concentration is increased flows to the low temperature regenerator 23 through the intermediate solution pipe 84 and the high temperature heat exchanger 50.

상기 중간용액은 상기 고온재생기(10)로부터 유입된 냉매증기가 내부에 흐르고 있는 가열기(25)에 의해서 가열된다. 그리고 상기 중간용액으로부터 냉매증기가 분리되어 흡수액의 농도는 더욱 상승한다. 상기 저온재생기(23)에서 가열된 농용액은 농용액배관(85)에 유입되고 상기 저온열교환기(40)를 거쳐서 상기 흡수기(32)로 흘러, 트레이(35)에서 상기 냉각수관(86)에 적하된다.The intermediate solution is heated by the heater 25 in which the refrigerant vapor flowing from the high temperature regenerator 10 flows therein. In addition, the refrigerant vapor is separated from the intermediate solution, and the concentration of the absorbent liquid is further increased. The agricultural solution heated in the cryogenic regenerator 23 flows into the agricultural liquid piping 85 and flows through the cryogenic heat exchanger 40 to the absorber 32, from the tray 35 to the cooling water pipe 86. It is dropped.

그리고, 흡수액은 상기 증발기(31)를 경유하여 들어오는 냉매증기를 흡수하여 농도가 낮아진다. 농도가 낮아진 흡수액은 상기 흡수액펌프(72)의 구동력에 의하여 저온열교환기(40) 및 고온열교환기(50)에서 예열되어 고온재생기(10)로 유입된다. 도면에 미설명된 도면부호 13은 버너에 연료를 공급하는 연료탱크이며, 15는 버너로 연소공기를 공급하는 송풍기이다. In addition, the absorption liquid absorbs the refrigerant vapor that enters through the evaporator 31, and the concentration thereof is lowered. The absorbent liquid having a lower concentration is preheated in the low temperature heat exchanger 40 and the high temperature heat exchanger 50 by the driving force of the absorbent liquid pump 72 and flows into the high temperature regenerator 10. Reference numeral 13, which is not described in the drawing, is a fuel tank for supplying fuel to the burner, and 15 is a blower for supplying combustion air to the burner.

한편, 도 2에 도시된 흡수식 냉온수기(1')는 용액냉각흡수기(90)를 더 포함하며, 희용액배관(83)에서 분기된 분기관(91)이 용액냉각흡수기(90)를 지난 저온열교환기(40)로 연장된다. Meanwhile, the absorption type cold and hot water heater 1 ′ shown in FIG. 2 further includes a solution cooling absorber 90, and the branch pipe 91 branched from the rare liquid pipe 83 passes the solution cooling absorber 90 at low temperature. Extends into the group 40.

도 1 및 도 2에 도시된 흡수식 냉온수기의 흡수기에 대해 구체적으로 살펴보면, 흡수기(32) 내부의 상단에 트레이(35)가 위치하고, 트레이(35) 아래에는 냉각수관(86)이 위치하며, 트레이(35)를 통해 산포된 흡수액(농용액)은 냉각수관(86)을 따라 흘러내리면서, 냉매의 증발과 취화리튬의 냉각 및 흡수 현상이 발생된다.Looking at the absorber of the absorption type cold and hot water heater shown in Figures 1 and 2 in detail, the tray 35 is located at the upper end of the absorber 32, the cooling water pipe 86 is located below the tray 35, the tray ( The absorbing liquid (a concentrated solution) dispersed through 35 flows down the cooling water pipe 86, and the evaporation of the refrigerant and the cooling and absorption of lithium embrittlement occur.

However, as shown in FIG. 3, the coolant pipes 86 are arranged in a bundle structure that is bent in a plurality of rows, and the first coolant pipe 86a located below the tray has a wetness rate of about 82.2%, but the bottom The 13th coolant pipe 86z has a wetting rate of about 23.3%.

이와 같은 결과는 1개의 트레이에서 흡수액이 산포되기 때문에 아래로 갈수록 흡수액의 쏠림현상이 발생하게 되며, 흡수액의 쏠림현상은 냉매의 증발과 취화리튬의 냉각 및 흡수를 악화시켜 제품의 성능을 떨어뜨린다.The result is that the absorbent liquid is scattered in one tray, so that the absorbent liquid tends to go downward, and the absorbent liquid deteriorates the evaporation of the refrigerant and the cooling and absorption of the embrittlement lithium.
