【発明の詳細な説明】 空気調整法及びその装置 発明の分野 本発明は、循環する吸湿液により気体から水蒸気を吸収するための方法及び装置 に係わり、より具体的には、吸収技術を利用する空気調整システムに関するもの である。[Detailed description of the invention] Air conditioning method and device field of invention The present invention provides a method and apparatus for absorbing water vapor from a gas by a circulating hygroscopic liquid. and, more specifically, air conditioning systems that utilize absorption technology. It is.
発明の背景及び概要 従来の蒸発装置では、液体が、１つ以上の段階もしくは効果を経て蒸発により濃 縮され、最終段階の蒸気は、通常、凝縮器内で冷却水と間接的に接触することで 凝縮される。Background and overview of the invention In conventional evaporators, a liquid is concentrated by evaporation through one or more stages or effects. The condensed and final stage steam is usually cooled by indirect contact with cooling water in the condenser. Condensed.
本発明は、蒸発システムから熱エネルギーを外部冷却水システムへ放熱する代り に、蒸発器から出る蒸気の熱エネルギーを利用し、高い熱効率の得られる蒸発作 用により液体を濃舘する方法を対象とするものである。The invention provides an alternative to dissipating thermal energy from the evaporation system to an external cooling water system. In addition, the thermal energy of the steam emitted from the evaporator is used to produce evaporation with high thermal efficiency. The subject is a method of concentrating a liquid depending on its purpose.
したがって、本発明の目的は、吸収技術を用いる空気調整システムの効率を改善 し、エネルギー消費を低減することにある。Therefore, it is an object of the present invention to improve the efficiency of air conditioning systems using absorption technology. and reduce energy consumption.
本発明が特に有用となるのは、気体から湿分を吸収することで希釈される吸湿塩 溶液により、空気等の気体を脱湿処理する場合である。使用済みの吸湿液は、再 利用のため、蒸発処理により再濃縮される。The present invention is particularly useful for hygroscopic salts that are diluted by absorbing moisture from a gas. This is a case where a gas such as air is dehumidified using a solution. The used moisture absorption liquid can be recycled. For utilization, it is reconcentrated by evaporation.
本発明の一実施例によれば、空気は、吸湿液と直接接触することで脱湿される。According to one embodiment of the invention, air is dehumidified by direct contact with a hygroscopic liquid.
吸湿液としては、酢酸カリウム、酢酸ナトリウム、炭酸カリウム、塩化カルシウ ム、塩化リチウム、臭化リチウム等のいずれか、もしくはこれらの混合物などの 易溶性の塩溶液が用いられる。これらの濃縮塩溶液は、水に対し強い親和力を示 すので、前記溶液上方で水蒸気圧が引下げられる。Hygroscopic liquids include potassium acetate, sodium acetate, potassium carbonate, and calcium chloride. lithium chloride, lithium bromide, etc., or a mixture of these. Easily soluble salt solutions are used. These concentrated salt solutions exhibit a strong affinity for water. Therefore, the water vapor pressure is lowered above the solution.
空気を、特定温度及び特定相対湿度のその種の溶液と接触させると、この溶液は 、その濃度が、平衡状態時に存在するよりも低い水蒸気圧を生じさせる限りにお いて、空気から水蒸気を吸収する。When air is brought into contact with such a solution at a certain temperature and a certain relative humidity, this solution , as long as its concentration produces a lower water vapor pressure than exists at equilibrium. and absorb water vapor from the air.
空気が、水蒸気の吸収により脱湿されると、吸湿液は、吸収した水分により次第 に希釈される。吸湿液の揮発性成分は水だけなので、溶液は水の蒸発処理によっ て再利用できる。この処理は、通例、吸湿液の水蒸気圧が大気圧を超える温度ま で吸湿液を加熱し、水分を蒸発させることで行なわれる。吸湿目的に適した濃縮 塩溶液の沸点上昇は著しい。一般に、水蒸気吸収による吸湿液の希釈の度合は比 較的小さく、したがって、１つ以上の段階又は効果による蒸発は、通例は不適で ある。このため、希釈された吸湿液は、通常、単一段階蒸発器での蒸発により再 生される。When air is dehumidified by absorbing water vapor, the hygroscopic liquid becomes diluted to Since water is the only volatile component of the hygroscopic solution, the solution is evaporated by water. can be reused. This process is typically carried out at temperatures where the water vapor pressure of the hygroscopic liquid exceeds atmospheric pressure. This is done by heating the hygroscopic liquid to evaporate the moisture. Concentration suitable for moisture absorption purposes The rise in the boiling point of salt solutions is significant. In general, the degree of dilution of a hygroscopic liquid due to water vapor absorption is relatively small and therefore evaporation by one or more stages or effects is usually unsuitable. be. For this reason, the diluted hygroscopic liquid is usually regenerated by evaporation in a single-stage evaporator. be born.
蒸発器で吸湿液を再生するため、気化熱に相応するエネルギー量が必要とされる 。付加エネルギーは、吸湿液をその沸とう温度まで加熱し、熱損失その他を補償 する必要がある。To regenerate the hygroscopic liquid in the evaporator, an amount of energy corresponding to the heat of vaporization is required. . The additional energy heats the hygroscopic liquid to its boiling temperature, compensating for heat loss, etc. There is a need to.
本発明の一好適実施例によれば、蒸発器から出る蒸気の熱エネルギーが、吸湿液 から水分を蒸発させるのに利用される。この処理は、蒸気を吸湿液と直接に接触 させるものだが、この接触は、吸湿液が蒸発器内で濃縮される前、及び（又は） 濃縮された後に行なわれる。蒸発器から出る蒸気は、熱交換部材の一方の表面と 直接接触する一方で、吸湿液が熱交換部材の他方の表面と接触する。According to one preferred embodiment of the invention, the thermal energy of the vapor leaving the evaporator is transferred to the hygroscopic liquid. It is used to evaporate water from This process brings the steam into direct contact with the hygroscopic liquid. However, this contact occurs before the hygroscopic liquid is concentrated in the evaporator and/or This is done after it has been concentrated. The steam coming out of the evaporator is connected to one surface of the heat exchange member. While in direct contact, the hygroscopic liquid contacts the other surface of the heat exchange member.
吸湿液は、好ましくは、熱交換部材の表面全体にわたり一様に薄膜が形成される 形式で流下するようにされる。The moisture absorbing liquid preferably forms a thin film uniformly over the entire surface of the heat exchange member. It is made to flow in the form.
加えて、空気は、吸湿液と接触して流れ、吸湿液から水分を蒸発させ、吸湿液上 方の水蒸気圧を引下げることにより、吸湿液からの水分蒸発を増強する。空気は 、水蒸気により飽和状態となり、気化熱が熱交換部材表面から除去される。In addition, air flows in contact with the wicking liquid, evaporating moisture from the wicking liquid, and moving the air over the wicking liquid. The evaporation of water from the hygroscopic liquid is enhanced by lowering the water vapor pressure of the hygroscopic liquid. The air is The heat exchanger becomes saturated with water vapor, and the heat of vaporization is removed from the surface of the heat exchange member.
吸湿液により蒸発器からの蒸気を凝縮することで、吸湿液は蒸発器の前方及び（ 又は）後方で濃縮されることになり、より高い仕事率と有意なエネルギー節減が 達成される。本発明の付加的な利点は、外部冷却水システムが不要になることに ある。By condensing the vapor from the evaporator with the hygroscopic liquid, the hygroscopic liquid flows in front of the evaporator and ( or) will be concentrated at the rear, resulting in higher power and significant energy savings. achieved. An additional advantage of the present invention is that it eliminates the need for an external cooling water system. be.
本発明は、したがって、単一の蒸発器によって、２段階の蒸発に似た効果を、そ れよりも可なり低いエネルギー比消費率で達成することができる。添付図面には 、蒸発器は１個だけ示されているが、１個以上の蒸発器を用いることも可能であ る。実際に本発明で用いられる蒸発器の数をｎ個とすれば、本発明の方法は、ｎ ＋１の段階又は効果に相当する蒸発を生じさせるものである。The present invention therefore provides a two-stage evaporation-like effect with a single evaporator. This can be achieved with significantly lower specific energy consumption rates. In the attached drawing , although only one evaporator is shown, it is possible to use more than one evaporator. Ru. If the number of evaporators actually used in the present invention is n, then the method of the present invention has n It produces evaporation corresponding to a +1 step or effect.
本発明を更に完全に理解し、かつまた本発明のそのほかの目的や利点を明らかに するため、以下では添付図面につき、本発明を説明する。To obtain a more complete understanding of the invention and to uncover other objects and advantages of the invention. For this purpose, the invention will be described below with reference to the accompanying drawings, in which: FIG.
図面の簡単な説明 添付図面は、空気調整システムの略示フローチャートである。このシステムでは 、空気の脱湿に用いられる吸湿塩溶液は、蒸発によって濃縮される。Brief description of the drawing The accompanying drawing is a schematic flowchart of the air conditioning system. In this system , hygroscopic salt solutions used for air dehumidification are concentrated by evaporation.
現在のところ好ましい実施例の説明 図示の通り、この空調システムは、冷却器１０１、蒸発凝縮器１０２、蒸発器１ ０３、吸湿器１０５を育している。吸湿液は、導管１０４を介して吸湿器１０５ へ供給され、導管１０６を介して流入する空気と直接接触せしめられ、空気から 湿分を除去する。空気と接触して湿分を吸収した吸湿液の少なくとも一部は、導 管１０７を介して冷却器１０１へ送られ、その他の部分は分岐導管１０８を介し て凝縮器１０２へ送られるのが好ましい。DESCRIPTION OF CURRENTLY PREFERRED EMBODIMENTS As shown in the figure, this air conditioning system includes a cooler 101, an evaporative condenser 102, an evaporator 1 03, growing a moisture absorber 105. The moisture absorbing liquid is passed through a conduit 104 to a moisture absorber 105. and is in direct contact with the air entering via conduit 106, and from the air Remove moisture. At least a portion of the hygroscopic liquid that has absorbed moisture in contact with the air is It is sent to the cooler 101 through a pipe 107, and the other part is sent through a branch pipe 108. Preferably, it is sent to the condenser 102.
凝縮器１０２は、間隔をおいて垂直方向に配置された１つ以上の従来型熱交換部 材１１２を育しているのが好ましい。これら熱交換部材１１２は、実質的に平行 な複数プレート対から成るようにするのが好ましい。これらのプレート対は、そ のエツジのところで連結され、ケーシング１１１内で複数の閉鎖スペースを形成 する。これ以外の熱交換部材配置、たとえばラジアル型の配置や背型の熱交換部 材の使用も可能である。熱交換部材間には開放通路が形成されている。熱交換部 材１１２の内部は、その上端部が水蒸気用の入口１２６に接続され、下端部が凝 縮物を放出する出口１２７に接続されている。複数の開口又は噴射ノズルを備え た分配器１２２は、各熱交換部材上方でケーシングを横断して延び、それぞれの 熱交換部材全体に、好ましくは実質的に一様に吸湿液を分配する。′ケーシング １１１は、好ましくは上端部に位置する空気出口１１６を存している。１つ以上 の空気人口１１５を、好ましくはケーシング下部に設けておく。ケーシングを通 過する空気流を上方へ導くため、好ましくは出口近くに羽根車１１４を配置して おく。Condenser 102 includes one or more conventional heat exchange sections spaced vertically. Preferably, the wood 112 is grown. These heat exchange members 112 are substantially parallel. Preferably, it is made up of a plurality of plate pairs. These plate pairs are connected at the edges of the casing 111 to form a plurality of closed spaces within the casing 111. do. Other heat exchange member arrangements, such as radial arrangement or dorsal heat exchange part It is also possible to use wood. Open passages are formed between the heat exchange members. heat exchange section Inside the material 112, its upper end is connected to the water vapor inlet 126, and its lower end is connected to the water vapor inlet 126. It is connected to an outlet 127 for discharging condensates. Equipped with multiple openings or injection nozzles A distributor 122 extends across the casing above each heat exchange member to The wicking liquid is preferably distributed substantially uniformly throughout the heat exchange member. 'casing 111 includes an air outlet 116, preferably located at the top end. one or more An air volume 115 is preferably provided in the lower part of the casing. through the casing An impeller 114 is preferably placed near the outlet to direct the passing airflow upward. put.
蒸発により濃縮する必要のある薄くなった吸湿液は、分岐導管１０８を介して凝 縮器２０２へ送られ、凝縮器の熱交換部材１１２の上方に配置された分配器！２ ２に入り、ここから、好ましくは一様な薄膜状に熱交換部材の外表を流れ下るよ うにされる。１つ又はそれ以上の熱交換部材１２５を有する蒸発器１０３のケー シング１０３頂部に接続された導管１２３を介して供給される水蒸気は、入口１ ２６から熱交換部材１１２内へ導入される。部材１１２の外表に沿って流下する 吸湿液は、蒸発器１０３から出る高温水蒸気との間接接触により加熱される。入 口１１５を介して供給され、熱交換部材の外側に沿ってケーシング内を流過する 空気は、吸湿液と直接接触することにより、その蒸気圧を引下げ、吸湿液の水分 を蒸発させる。この水蒸気は、出口１１６を経て凝縮器から流出する空気と一緒 に排出される。入口１１５から入りケーシング１１１を流過する掃気は、入念に 平衡化しておくのが好ましい。なぜなら、吸湿液を冷却し、蒸発冷却なしに冷却 器１０１の熱交換表面全体を流れるのに必要な空気量は、既述のように、蒸発冷 却をともなう場合より約１０倍多いからである。The diluted hygroscopic liquid that needs to be concentrated by evaporation is condensed via branch conduit 108. Distributor sent to the condenser 202 and located above the condenser heat exchange member 112! 2 2, from which it flows down the outer surface of the heat exchange member, preferably in the form of a uniform thin film. be ignored. The case of the evaporator 103 with one or more heat exchange elements 125 Water vapor supplied via a conduit 123 connected to the top of the thing 103 is supplied to the inlet 1 26 into the heat exchange member 112. Flows down along the outer surface of the member 112 The hygroscopic liquid is heated by indirect contact with high temperature steam exiting the evaporator 103. Enter is supplied through the port 115 and flows through the casing along the outside of the heat exchange member. By coming into direct contact with the hygroscopic liquid, air lowers its vapor pressure and absorbs the moisture in the hygroscopic liquid. evaporate. This water vapor is combined with the air exiting the condenser via outlet 116. is discharged. The scavenging air entering from the inlet 115 and flowing through the casing 111 is carefully Preferably, it is equilibrated. Because it cools hygroscopic liquid and cools without evaporative cooling. The amount of air required to flow over the entire heat exchange surface of the vessel 101 is determined by the evaporative cooling as described above. This is because the number of cases is about 10 times higher than that of cases involving failure.
したがって、一般的に言えば、入口１１５に導入される空気の９０％は、凝縮器 １０２と接触する前に回収することができる。この回収された空気流は、図には 示されていない。吸湿液から水分を蒸発させるには熱エネルギーが必要だが、こ の熱エネルギーは、蒸気を凝縮させる熱交換部材間部の水蒸気から取出される。Therefore, generally speaking, 90% of the air introduced into the inlet 115 is 102 before coming into contact with it. This recovered airflow is shown in the figure Not shown. Thermal energy is required to evaporate moisture from a hygroscopic liquid, but this Thermal energy is extracted from the water vapor between the heat exchange elements condensing the vapor.
水蒸気と吸湿液との間接接触により熱交換部材内に生じる凝縮物は、出口１２７ を経て熱交換器から出て、導管１２８を経てケーシング底部の液体プール１３８ に入る。Condensate formed in the heat exchange member due to indirect contact between the water vapor and the hygroscopic liquid is removed from the outlet 127. exits the heat exchanger via conduit 128 to a liquid pool 138 at the bottom of the casing. to go into.

It enters a container or vat 139 located below the lower end. pre-concentrated hygroscopic liquid then passes through conduit 129 and preferably through heat exchanger 130 to evaporator 103. sent to. This evaporates through conduits 134, 137 before entering evaporator 103. By indirect contact with the concentrated hygroscopic liquid collected in advance from the container 103, the temperature of the pre-concentrated hygroscopic liquid is increased. This is to increase the degree of

The hygroscopic liquid flowing down the surface of the heat exchanger is heated to its boiling point. It is heated and the water is evaporated. The concentrated hygroscopic liquid flows to the bottom of the two casings 136. and is collected via the discharge pipe 134. A portion of the concentrated hygroscopic liquid is transferred to conduit 1 35 and is returned to the distributor 133. The remaining concentrated hygroscopic liquid is preferably transferred to conduit 1 37, passes through the heat exchanger 130, and enters the cooler 101 through the inlet 140. Alright may also be concentrated depending on the required degree of cooling of the humid air or gas flowing through conduit 106. All or part of the hygroscopic liquid is directly transferred from the heat exchanger 103 to the absorber 105 (not shown). You may also send it to

The water vapor is recovered from the evaporator 103 and sent to the condenser 102 via conduit 123. There, it is condensed and used as a heating medium for pre-concentration of the hygroscopic liquid.
吸収器１０５から冷却器１０１へ送られる吸湿液は、凝縮器１０２の熱交換部材 と似た設計の熱交換部材１０９の入口１４０へ入る。冷却器の熱交換部材は、凝 縮器のそれの下方に配置するのが好ましい。吸湿液は、熱交換部材１０９の上方 に配置された分配器１１１から供給される冷却液と間接接触せしめられる。冷却 液は、熱交換部材の外表全体に、好ましくは一様に薄膜の形で流下するようにす る。冷却液は、適当な液体であればどのようなものでもよいが、主として、凝縮 器１０２からの凝縮物を用いるのが好ましい。この凝縮物は、冷却器１０１と凝 縮器１０２との熱交換部材１０９．１１２を包囲しているケーシングＩＩＩの底 部に集められている。The hygroscopic liquid sent from the absorber 105 to the cooler 101 is transferred to the heat exchange member of the condenser 102. into the inlet 140 of the heat exchange member 109 of similar design.

この凝縮物１１９は、液体ブール１３８から、好ましくはポンプ１１７により導 管１１８を介して分配器】１０へ送られる。この凝縮物の利用が好ましいのは、 凝縮物が実質的に蒸溜水であるため、熱交換部材１０９の熱交換面上に垢や沈着 物が付着することがないからである。This condensate 119 is drawn from the liquid boule 138, preferably by pump 117. It is sent to distributor 10 via pipe 118. The preferred use of this condensate is Since the condensate is essentially distilled water, no dirt or deposits will form on the heat exchange surface of the heat exchange member 109. This is because objects will not stick to it.
付加的に冷却水を、たとえば液体ブール１３８に加えることも、もちろん可能で ある。しかし、既述のように、外部の冷却水源を用いる公知冷却器と異なり、凝 縮器１０２と冷却器１０１での蒸発冷却に用いられる冷却水の少なくとも大部分 を、導管１０６を流れる多湿空気流から得ることができる。It is of course also possible to additionally add cooling water, for example to the liquid boule 138. be. However, as mentioned above, unlike known coolers that use an external cooling water source, At least most of the cooling water used for evaporative cooling in the condenser 102 and cooler 101 can be obtained from the humid air flow flowing through conduit 106.
熱交換部材１０９．１１２とケーシング１１１は冷却塔】１３を形成している。The heat exchange elements 109, 112 and the casing 111 form a cooling tower 13.
羽根車１１４により、空気が、この冷却塔から送出される。既述のように、冷却 液／凝縮物１１９はケーシング底部に集められ、ポンプ１１７により導管１１８ を経て分配器１１０へ送られるようにするのが好ましい。冷却液１１９のレベル は実質的にコンスタントに＃ＩｇＩＪシ、維持するのが好ましい。An impeller 114 pumps air out of the cooling tower. As mentioned above, cooling Liquid/condensate 119 is collected at the bottom of the casing and pumped into conduit 118 by pump 117. Preferably, the water is sent to the distributor 110 via the . Coolant 119 level It is preferable to maintain #IgIJ substantially constantly.
ケーシング又は／ハウジング１１１内を貫流し、冷却器１０１の熱交換器１０９ の外表面全体に沿って流れる空気は、冷却液でぬれた外表面を直接接触すること により、冷却液から水分を蒸発させる。蒸発した水分は空気流により除去される 。また、水分の蒸発により、熱交換部材１０９内を流れる吸湿液の熱が除去され る。冷却された吸湿液は、熱交換部材１０９から出口１２０を経て回収され、導 管１２１ １０５を経て吸収器１０４へ戻される。The heat exchanger 109 of the cooler 101 flows through the casing or/housing 111. The air flowing along the entire outer surface of the evaporates water from the coolant. Evaporated moisture is removed by air flow . Furthermore, due to the evaporation of water, the heat of the moisture-absorbing liquid flowing inside the heat exchange member 109 is removed. Ru. The cooled hygroscopic liquid is collected from the heat exchange member 109 through the outlet 120 and introduced into the It is returned to the absorber 104 via pipes 121 and 105.
例 空気が、乾燥空気８．１００ｋｇ／ｈの率及び次の条件で吸収器１０５へ導入さ れる：ｔ＝３０℃乾球温度、２７℃湿球温度； ｘ ＝ ０．０２１ ｋｇ Ｈ ２０／ ｋｇ乾燥空気。example Air is introduced into the absorber 105 at a rate of 8.100 kg/h of dry air and the following conditions: : t = 30℃ dry bulb temperature, 27℃ wet bulb temperature; x = 0.021 kg H 20/kg dry air.
吸湿後、吸湿器１０５がら空気は、乾燥空気８．１００ｋｇ／ｈの率で、下記条 件にて放出される：ｔ＝３７℃乾球温度、２０℃湿球温度、ｘ ＝ ０．００６ ５ ｋｇ ｊｂＯ／ ｋｇ乾燥空気。吸収された水分の量は、８，１００（０， ０２１−０，００６５）＝１１７ｋｇと計算される。冷却器１０１へ伝達された 熱量は、３８．０００ｋｇ／ｈ吸湿液の場合に２００．０００ｋＪ／ｈである。After absorbing moisture, the air from the moisture absorber 105 is supplied with dry air at a rate of 8.100 kg/h under the following conditions. Emitted at: t = 37℃ dry bulb temperature, 20℃ wet bulb temperature, x = 0.006 5 kg jbO/kg dry air. The amount of water absorbed is 8,100 (0, 021-0,0065)=117kg. transmitted to cooler 101 The amount of heat is 200.000 kJ/h in the case of 38.000 kg/h hygroscopic liquid.
吸湿段階中、導管１０８内の液体流は、はぼ１１７ｋｇ／ｈの水分を空気から除 去した。吸湿液が、熱交換により蒸発器温度に高められたのち、単一の段階で蒸 発せしめられる場合、エネルギー消費は、蒸発した水分ｋｇ当りほぼ蒸気１ ｋ ｇである。吸湿液用の前蒸発器及び（又は）後蒸発器である、本発明による蒸発 凝縮器を用いることにより、蒸発用に要するエネルギー量は、蒸発器のみを用い た場合と比較して約１．５〜１．９倍だけ低減される。During the moisture absorption phase, the liquid flow in conduit 108 removes approximately 117 kg/h of moisture from the air. I left. The hygroscopic liquid is brought to the evaporator temperature by heat exchange and then evaporated in a single step. When emitted, the energy consumption is approximately 1 k of steam per kg of water evaporated. It is g. The evaporator according to the invention is a pre-evaporator and/or a post-evaporator for hygroscopic liquids. By using a condenser, the amount of energy required for evaporation can be reduced by using only the evaporator. It is reduced by about 1.5 to 1.9 times compared to the case where
既述の熱交換部材の代りに、背型の熱交換部材を用いてもよい。また、薄くなっ た塩溶液の濃縮度が低く、したがって、その沸点上昇が、なだらかであり、この ため蒸発が２段階もしくはそれ以上の従来式の蒸発段階で可能になる場合は、本 発明を、第２段階もしくはそれ以後の段階からの水蒸気を凝縮するのに用いるこ とができる。A back type heat exchange member may be used instead of the heat exchange member described above. Also, it becomes thinner The concentration of the salt solution is low, and therefore its boiling point rises gradually; Therefore, if evaporation is possible in two or more conventional evaporation stages, this The invention may be used to condense water vapor from a second or subsequent stage. I can do it.
空気流の湿度及び温度は、もちろん、空気流内での噴霧水蒸発により制御するこ とができる。Humidity and temperature of the air stream can of course be controlled by spray water evaporation within the air stream. I can do it.
