Description

除湿用デシカント装置Desiccant device for dehumidification
　本発明は、除湿用デシカント装置に関する。 The present invention relates to a desiccant device for dehumidification.
　除湿用デシカント装置は、水分吸着剤で低湿度の空気を作り出す空調機器である。除湿用デシカント装置で低湿度の空気を室内等に供給することにより、室内等の温度をそれほど下げなくても快適性を得ることができる。除湿用デシカント装置は、給気用ファン、デシカント部、冷却部、加熱部、再生用ファン等を備えている。
　給気用ファンで室外から導入した空気をデシカント部に流すことにより、デシカント部で空気中の水分を吸着する。デシカント部を流れた空気がデシカント部で除湿される。除湿された空気を冷却部で冷却し、室内に流すことにより室内の快適性が得られる。 A desiccant device for dehumidification is an air conditioner that creates low-humidity air with a moisture adsorbent. By supplying low-humidity air into a room or the like with a desiccant device for dehumidification, comfort can be obtained without reducing the temperature of the room or the like so much. The desiccant device for dehumidification includes an air supply fan, a desiccant unit, a cooling unit, a heating unit, a regeneration fan, and the like.
The air introduced from the outside by the air supply fan is caused to flow to the desiccant part, so that moisture in the air is adsorbed by the desiccant part. The air flowing through the desiccant part is dehumidified in the desiccant part. Indoor air comfort can be obtained by cooling the dehumidified air in the cooling section and flowing it into the room.
　一方、デシカント部に吸着された水分を除去して再生する際には、加熱部で乾燥させた空気をデシカント部に流す。乾燥空気を流すことにより、デシカント部に吸着されている水分を乾燥空気に含ませて、デシカント部から除去する。デシカント部から水分が除去されることによりデシカント部が再生される。水分を含んだ空気は再生用ファンで室外へ排気される（特許文献１）。
　しかし、デシカント部で水分を充分に吸着するためには、デシカント部の形状を大きく確保する必要があり、この観点から改良の余地が残されている。 On the other hand, when the water adsorbed on the desiccant part is removed and regenerated, air dried by the heating part is passed through the desiccant part. By flowing dry air, moisture adsorbed on the desiccant part is included in the dry air and removed from the desiccant part. The desiccant part is regenerated by removing water from the desiccant part. Air containing moisture is exhausted to the outside by a regeneration fan (Patent Document 1).
However, in order to sufficiently adsorb moisture in the desiccant portion, it is necessary to ensure a large shape of the desiccant portion, and there is room for improvement from this viewpoint.

　なお、図１においては、除湿用デシカント装置１０の構成の理解を容易にするために、第１微小除湿剤（除湿剤）２４、第２微小除湿剤（除湿剤）３２および第３微小除湿剤（除湿剤）３５を省略して示す。
　図１に示すように、除湿用デシカント装置１０は、空気を流す流路１２の内部１３に設けられている。除湿用デシカント装置１０は、流路１２の内部１３に収容された第１デシカント１４、第２デシカント１６、第３デシカント１８を備えている。
　以下、流路１２において、第１デシカント１４が配置されている側を上流側、第３デシカント１８が配置されている側を下流側として説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, in order to facilitate understanding of the configuration of the desiccant device 10 for dehumidification, the first micro dehumidifier (dehumidifier) 24, the second micro dehumidifier (dehumidifier) 32, and the third micro dehumidifier. (Dehumidifier) 35 is omitted.
As shown in FIG. 1, the desiccant device 10 for dehumidification is provided in the inside 13 of the flow path 12 through which air flows. The dehumidifying desiccant device 10 includes a first desiccant 14, a second desiccant 16, and a third desiccant 18 accommodated in the interior 13 of the flow path 12.
Hereinafter, in the flow path 12, the side on which the first desiccant 14 is disposed is described as an upstream side, and the side on which the third desiccant 18 is disposed is described as a downstream side.
　流路１２は、たとえば、断面円形に形成されている。流路１２は、第１デシカント１４の上流側から第１デシカント１４に向けて高相対湿度の空気を矢印Ａの如く流すことができる。第１デシカント１４、第２デシカント１６、および第３デシカント１８を通過した乾燥空気を矢印Ｂの如く流路１２の下流側に流すことができる。
　また、第３デシカント１８の下流側から第３デシカント１８に向けて低相対湿度の空気を矢印Ｃの如く流すことができる。第３デシカント１８、第２デシカント１６および第１デシカント１４を通過した高相対湿度の空気を矢印Ｄの如く流路１２の上流側に流すことができる。 The flow path 12 is formed, for example, in a circular cross section. The flow path 12 can flow high relative humidity air as indicated by an arrow A from the upstream side of the first desiccant 14 toward the first desiccant 14. The dry air that has passed through the first desiccant 14, the second desiccant 16, and the third desiccant 18 can flow to the downstream side of the flow path 12 as indicated by arrow B.
Further, air having a low relative humidity can flow from the downstream side of the third desiccant 18 toward the third desiccant 18 as indicated by an arrow C. High relative humidity air that has passed through the third desiccant 18, the second desiccant 16, and the first desiccant 14 can flow to the upstream side of the flow path 12 as indicated by an arrow D.
　図２、図３に示すように、第１デシカント１４は、渦巻状に巻回（巻きめぐら）された第１シート２１と、第１シート２１に多量の個数が含まれる第１微小除湿剤２４と、第１シート２１間の間隔Ｓ１を確保する除湿剤２５とを備えている。
　第１シート２１間の間隔Ｓ１を除湿剤２５で確保することにより、間隔Ｓ１で空気の流路を確保できる。すなわち、除湿剤２５は、第１シート２１間の間隔Ｓ１を確保するスペーサとしての役割と、補助的な除湿剤としての役割を兼ねる。以下、補助的な除湿剤２５を、第１スペーサ除湿剤２５という。 As shown in FIGS. 2 and 3, the first desiccant 14 includes a first sheet 21 wound in a spiral shape, and a first minute dehumidifying agent 24 in which a large number is included in the first sheet 21. And a dehumidifying agent 25 that secures the interval S <b> 1 between the first sheets 21.
By securing the space S1 between the first sheets 21 with the dehumidifying agent 25, the air flow path can be secured at the space S1. That is, the dehumidifying agent 25 serves both as a spacer that secures the interval S1 between the first sheets 21 and as an auxiliary dehumidifying agent. Hereinafter, the auxiliary dehumidifying agent 25 is referred to as a first spacer dehumidifying agent 25.
　第１シート２１は、例えば、幅寸法Ｔ１（図４参照）に形成され、第１微小除湿剤２４を含んだ帯状の不織布である。第１微小除湿剤２４は、第１スペーサ除湿剤２５と比較して微小な除湿剤である。第１シート２１の内部２２に複数の第１微小除湿剤２４が含まれており、第１スペーサ除湿剤２５が第１シート２１の間に間隔をおいて配置されている。
　第１微小除湿剤２４と第１スペーサ除湿剤２５とは、たとえば、水分（水蒸気）の吸着性に優れたシリカゲル等の素材で形成されている。第１シート２１の不織布繊維の内部２２に複数の第１微小除湿剤２４が配置されることにより、不織布繊維の間を通って到着した水分は第１微小除湿剤２４に吸着される。これにより、第１デシカント１４の水分の吸着性を高めることができる。 The 1st sheet | seat 21 is the strip | belt-shaped nonwoven fabric formed in the width dimension T1 (refer FIG. 4) and containing the 1st micro dehumidifier 24, for example. The first minute dehumidifying agent 24 is a minute dehumidifying agent as compared with the first spacer dehumidifying agent 25. A plurality of first minute dehumidifying agents 24 are included in the interior 22 of the first sheet 21, and the first spacer dehumidifying agents 25 are arranged between the first sheets 21 at intervals.
The first minute dehumidifying agent 24 and the first spacer dehumidifying agent 25 are formed of a material such as silica gel having excellent moisture (water vapor) adsorbability, for example. By arranging a plurality of first fine dehumidifying agents 24 in the interior 22 of the nonwoven fabric fibers of the first sheet 21, moisture arriving through the nonwoven fabric fibers is adsorbed by the first fine dehumidifying agents 24. Thereby, the water | moisture-content adsorptivity of the 1st desiccant 14 can be improved.
　また、第１スペーサ除湿剤２５が配置されることにより、第１シート２１が渦巻状に巻回された状態において、第１シート２１間の間隔Ｓ１が第１スペーサ除湿剤２５で確保されている。第１スペーサ除湿剤２５がスペーサの役割も兼ねることにより、スペーサを個別に備える必要がなく、構成の簡素化が図れる。 In addition, since the first spacer dehumidifying agent 25 is arranged, the first spacer 21 is secured in the space S1 between the first sheets 21 in a state where the first sheet 21 is spirally wound. . Since the first spacer dehumidifying agent 25 also serves as a spacer, it is not necessary to separately provide a spacer, and the configuration can be simplified.
　このように、第１シート２１の間に複数の第１スペーサ除湿剤２５を配置することにより、第１シート２１間に空間Ｓ１を簡単な構成で確実に確保できる。
　また、第１スペーサ除湿剤２５は、たとえば、水分の吸着性に優れたシリカゲル等の素材で形成されている。水分の吸着性に優れた素材を第１スペーサ除湿剤２５に使用することにより、第１微小除湿剤２４による空気中の水分の吸着性に加え、その性能を一層高めることができる。 Thus, by arranging the plurality of first spacer dehumidifying agents 25 between the first sheets 21, the space S1 can be reliably secured between the first sheets 21 with a simple configuration.
Further, the first spacer dehumidifier 25 is formed of a material such as silica gel having excellent moisture adsorbability, for example. By using a material excellent in moisture adsorptivity for the first spacer dehumidifier 25, in addition to the moisture adsorptivity in the air by the first minute dehumidifier 24, the performance can be further enhanced.
　第１微小除湿剤２４および第１スペーサ除湿剤２５は、実施形態では、外径が異なる球状に形成され、表面、内部に多数の細孔２６（図５（ａ）も参照）が形成されている。第１微小除湿剤２４および第１スペーサ除湿剤２５に多数の細孔２６が形成されることにより、第１微小除湿剤２４および第１スペーサ除湿剤２５の表面積を大きく確保し、水分の吸着性を高めることができる。
　第１微小除湿剤２４および第１スペーサ除湿剤２５は球状に限らず、異形、粉末も使用できる。
　第１スペーサ除湿剤２５の細孔は、第１微小除湿剤２４の細孔２６に対して、同一サイズであることが好ましいが、細孔径サイズが異なるものでも水分の吸着を補強するものとして使用できる。 In the embodiment, the first minute dehumidifying agent 24 and the first spacer dehumidifying agent 25 are formed in spherical shapes having different outer diameters, and a large number of pores 26 (see also FIG. 5A) are formed on the surface and inside. Yes. By forming a large number of pores 26 in the first minute dehumidifying agent 24 and the first spacer dehumidifying agent 25, the surface area of the first minute dehumidifying agent 24 and the first spacer dehumidifying agent 25 is ensured to be large, and the moisture adsorptivity. Can be increased.
The first minute dehumidifying agent 24 and the first spacer dehumidifying agent 25 are not limited to a spherical shape, and may be modified or powdered.
The pores of the first spacer dehumidifying agent 25 are preferably the same size as the pores 26 of the first minute dehumidifying agent 24, but even those having different pore size sizes are used to reinforce moisture adsorption. it can.
　図３、図４に示すように、第１シート２１（すなわち、不織布）の内部には複数の第１微小除湿剤２４が複数担持される。さらに、第１シート２１の間に複数の第１スペーサ除湿剤２５が含まれる。第１シート２１を不織布で形成することにより、第１シート２１の内部２２に複数の第１微小除湿剤２４を安定させた状態で保持できる。
　複数の第１微小除湿剤２４が含まれる第１シート２１が一端部２１ａを中心にして渦巻き状に巻回される。第１シート２１を渦巻き状に巻回するだけの簡単な構成で第１デシカント１４を容易に形成できる。
　また、第１デシカント１４は、第１シート２１を渦巻状に巻回することにより、外形が正面視円形状に形成される。よって、第１デシカント１４を、断面円形の流路１２に容易に配置できる。 As shown in FIGS. 3 and 4, a plurality of first minute dehumidifying agents 24 are carried inside the first sheet 21 (that is, the nonwoven fabric). Further, a plurality of first spacer dehumidifiers 25 are included between the first sheets 21. By forming the 1st sheet | seat 21 with a nonwoven fabric, the some 1st micro dehumidifier 24 can be hold | maintained in the inside 22 of the 1st sheet | seat 21 in the stabilized state.
A first sheet 21 including a plurality of first minute dehumidifying agents 24 is wound in a spiral shape around one end 21a. The first desiccant 14 can be easily formed with a simple configuration in which the first sheet 21 is wound in a spiral shape.
The first desiccant 14 has a circular outer shape when the first sheet 21 is wound in a spiral shape. Therefore, the 1st desiccant 14 can be easily arrange | positioned to the flow path 12 with a circular cross section.

　図５（ａ）～５（ｃ）、図７において、第１微小除湿剤２４、第２微小除湿剤３２、第３微小除湿剤３５における水分の吸着量について説明する。図７に示すグラフは、縦軸に除湿剤の水分吸着量を示し、横軸に相対湿度をとった、除湿剤の吸着水分量の相対湿度依存特性を示す。破線で示すグラフＧ４は、第１デシカント１４に含まれる第１微小除湿剤２４の水分の吸着量と相対湿度との関係を示す。実線で示すグラフＧ５は、第２デシカント１６に含まれる第２微小除湿剤３２の水分の吸着量と相対湿度との関係を示す。一点鎖線で示すグラフＧ６は、第３デシカント１８に含まれる第３微小除湿剤３５の水分の吸着量と相対湿度との関係を示す。 5 (a) to 5 (c) and FIG. 7, the amount of moisture adsorbed by the first micro dehumidifier 24, the second micro dehumidifier 32, and the third micro dehumidifier 35 will be described. In the graph shown in FIG. 7, the vertical axis indicates the moisture adsorption amount of the dehumidifying agent, and the horizontal axis indicates the relative humidity dependence characteristic of the absorbed moisture amount of the dehumidifying agent. A graph G4 indicated by a broken line shows the relationship between the moisture adsorption amount of the first microdehumidifier 24 included in the first desiccant 14 and the relative humidity. A graph G5 indicated by a solid line shows the relationship between the amount of moisture adsorbed by the second minute dehumidifier 32 contained in the second desiccant 16 and the relative humidity. A graph G6 indicated by an alternate long and short dash line indicates the relationship between the amount of moisture adsorbed by the third microhumidifier 35 contained in the third desiccant 18 and the relative humidity.
　グラフＧ４で示すように、第１微小除湿剤２４は相対湿度が高い領域Ｅ１において水分の吸着量が大きい。グラフＧ５で示すように、第２微小除湿剤３２は相対湿度が中程度の領域Ｅ２において水分の吸着量が大きい。グラフＧ６で示すように、第３微小除湿剤３５は、相対湿度が低い領域Ｅ３においても吸着性能を示すが、水分の吸着量は比較的少なく、相対湿度が高い領域においても水分の吸着量は大きくならない。ここで相対湿度が高い領域Ｅ１とは、グラフＧ４とグラフＧ５の交点における相対湿度よりも相対湿度が高い領域である。相対湿度が低い領域Ｅ３とは、グラフＧ５とグラフＧ６との交点における相対湿度よりも相対湿度が低い領域であり、相対湿度が中程度の領域Ｅ２は、Ｅ１とＥ３との間の領域である。 As shown by the graph G4, the first minute dehumidifying agent 24 has a large moisture adsorption amount in the region E1 where the relative humidity is high. As shown by the graph G5, the second minute dehumidifying agent 32 has a large moisture adsorption amount in the region E2 where the relative humidity is medium. As shown in the graph G6, the third minute dehumidifying agent 35 exhibits the adsorption performance even in the region E3 where the relative humidity is low, but the moisture adsorption amount is relatively small, and the moisture adsorption amount is also high in the region where the relative humidity is high. Does not grow. Here, the region E1 where the relative humidity is high is a region where the relative humidity is higher than the relative humidity at the intersection of the graph G4 and the graph G5. The region E3 where the relative humidity is low is a region where the relative humidity is lower than the relative humidity at the intersection of the graph G5 and the graph G6, and the region E2 where the relative humidity is medium is a region between E1 and E3. .
　よって、相対湿度が高い領域Ｅ１において、空気中の水分を第１微小除湿剤２４で吸着することにより、空気中の水分を効率よく吸着できる。また、相対湿度が中程度の領域Ｅ２において、空気中の水分を第２微小除湿剤３２で吸着することにより、空気中の水分を効率よく吸着できる。さらに、相対湿度が低い領域Ｅ３において、空気中の水分を第３微小除湿剤３５で吸着することにより、空気中の水分を効率よく吸着できる。 Therefore, in the region E1 where the relative humidity is high, the moisture in the air can be efficiently adsorbed by adsorbing the moisture in the air with the first minute dehumidifier 24. Further, in the region E2 where the relative humidity is medium, the moisture in the air can be efficiently adsorbed by adsorbing the moisture in the air with the second minute dehumidifier 32. Furthermore, in the region E3 where the relative humidity is low, moisture in the air can be efficiently adsorbed by adsorbing moisture in the air with the third minute dehumidifying agent 35.
　図１に戻って、流路１２の内部１３において、第１デシカント１４は第２デシカント１６の上流側に隣接して配置されている。第２デシカント１６は第３デシカント１８の上流側に隣接して配置されている。
　よって、流路１２の上流側から相対湿度が高い空気を矢印Ａの如く流すことにより、第１デシカント１４の第１微小除湿剤２４で空気中の水分を効率よく吸着できる。 Returning to FIG. 1, the first desiccant 14 is disposed adjacent to the upstream side of the second desiccant 16 in the interior 13 of the flow path 12. The second desiccant 16 is disposed adjacent to the upstream side of the third desiccant 18.
Therefore, by flowing air having a high relative humidity from the upstream side of the flow path 12 as indicated by an arrow A, moisture in the air can be efficiently adsorbed by the first minute dehumidifying agent 24 of the first desiccant 14.
　第１デシカント１４の第１微小除湿剤２４で空気中の水分が吸着されることにより、第１デシカント１４から流出した空気は、相対湿度が中程度に抑えられている。中程度の相対湿度の空気を第１デシカント１４から第２デシカント１６に流す。よって、第２デシカント１６の第２微小除湿剤３２で空気中の水分を効率よく吸着できる。 As the moisture in the air is adsorbed by the first minute dehumidifier 24 of the first desiccant 14, the relative humidity of the air flowing out from the first desiccant 14 is suppressed to a medium level. Medium relative humidity air is passed from the first desiccant 14 to the second desiccant 16. Therefore, moisture in the air can be efficiently adsorbed by the second micro-humidifier 32 of the second desiccant 16.
　第２デシカント１６の第２微小除湿剤３２で空気中の水分が吸着されることにより、第２デシカント１６から流出した空気は、相対湿度がある程度低く抑えられている。低く抑えられた相対湿度の空気を第２デシカント１６から第３デシカント１８に流す。よって、第３デシカント１８の第３微小除湿剤３５で空気中の水分を効率よく吸着できる。
　これにより、第３デシカント１８から矢印Ｂの如く流出した空気を乾燥空気とすることができる。 Since the moisture in the air is adsorbed by the second minute dehumidifying agent 32 of the second desiccant 16, the relative humidity of the air flowing out from the second desiccant 16 is suppressed to a certain degree. Low relative humidity air is flowed from the second desiccant 16 to the third desiccant 18. Therefore, moisture in the air can be efficiently adsorbed by the third minute dehumidifying agent 35 of the third desiccant 18.
Thereby, the air which flowed out from the 3rd desiccant 18 as shown by arrow B can be made into dry air.
　一方、第１微小除湿剤２４、第２微小除湿剤３２、第３微小除湿剤３５に吸着した水分を除去する場合には、流路１２の下流側から再生用の低相対湿度の空気（乾燥空気）を矢印Ｃの如く流す。低相対湿度の空気を第３デシカント１８に流すことにより、第３微小除湿剤３５に吸着した水分を空気中に効率よく含ませることができる。すなわち、第３微小除湿剤３５に吸着した水分を効率よく除去できる。 On the other hand, when water adsorbed on the first micro dehumidifier 24, the second micro dehumidifier 32, and the third micro dehumidifier 35 is removed, air having a low relative humidity for regeneration (dried) is dried from the downstream side of the flow path 12. Air) as shown by arrow C. By flowing low relative humidity air through the third desiccant 18, the moisture adsorbed on the third minute dehumidifier 35 can be efficiently contained in the air. That is, the moisture adsorbed on the third minute dehumidifying agent 35 can be removed efficiently.
　第３デシカント１８から流出した空気は、相対湿度がある程度高められている。相対湿度がある程度高められた空気を第２デシカント１６に流すことにより、第２微小除湿剤３２に吸着した水分を空気中に効率よく含ませることができる。すなわち、第２微小除湿剤３２に吸着した水分を効率よく除去できる。 The air flowing out from the third desiccant 18 has a relatively high relative humidity. By flowing air having a relatively high relative humidity to the second desiccant 16, the moisture adsorbed on the second minute dehumidifier 32 can be efficiently contained in the air. That is, the moisture adsorbed on the second minute dehumidifier 32 can be efficiently removed.
　第２デシカント１６から流出した空気は、相対湿度が中程度に高められている。相対湿度が中程度に高められた空気を第１デシカント１４に流すことにより、第１微小除湿剤２４に吸着した水分を空気中に効率よく含ませることができる。すなわち、第１微小除湿剤２４に吸着した水分を効率よく除去できる。
　第１デシカント１４から流出した相対湿度が高い空気は矢印Ｄの如く上流側に流れる。
　これにより、第１微小除湿剤２４、第２微小除湿剤３２、第３微小除湿剤３５に吸着した水分を除去でき、第１微小除湿剤２４、第２微小除湿剤３２、第３微小除湿剤３５を再使用状態に再生できる。 The air flowing out from the second desiccant 16 has a relatively high relative humidity. By flowing air having a relatively high relative humidity to the first desiccant 14, the moisture adsorbed on the first minute dehumidifier 24 can be efficiently contained in the air. That is, the moisture adsorbed on the first minute dehumidifying agent 24 can be efficiently removed.
The air having a high relative humidity flowing out from the first desiccant 14 flows upstream as indicated by an arrow D.
Thereby, the water | moisture content adsorb | sucked to the 1st micro dehumidifier 24, the 2nd micro dehumidifier 32, and the 3rd micro dehumidifier 35 can be removed, and the 1st micro dehumidifier 24, the 2nd micro dehumidifier 32, the 3rd micro dehumidifier 35 can be reproduced in a reuse state.
　このように、第１デシカント１４、第２デシカント１６、第３デシカント１８を上流側から下流側へ向けて順に配置することにより、相対湿度が高い領域から相対湿度が低い領域までの全領域において空気中の水分を効率よく吸着できる。すなわち、第１デシカント１４、第２デシカント１６、第３デシカント１８に含まれる各微小除湿剤２４，３２，３５の水分の吸着性を空気中の相対湿度に応じて異ならせることができる。
　これにより、多孔質直径が同じ除湿剤を使用した除湿用デシカント装置と比べて、除湿用デシカント装置１０を小型にできる。 As described above, by arranging the first desiccant 14, the second desiccant 16, and the third desiccant 18 in order from the upstream side to the downstream side, air in the entire region from the region where the relative humidity is high to the region where the relative humidity is low. It is possible to adsorb the moisture in it efficiently. That is, the moisture adsorptivity of the minute dehumidifiers 24, 32, and 35 contained in the first desiccant 14, the second desiccant 16, and the third desiccant 18 can be varied according to the relative humidity in the air.
Thereby, the desiccant apparatus 10 for dehumidification can be reduced in size compared with the desiccant apparatus for dehumidification using the dehumidifier with the same porous diameter.
　つぎに、図８（ａ）および８（ｂ）、図９（ａ）および９（ｂ）において、除湿用デシカント装置１０の使用例を説明する。
　図８（ａ）に示すように、一体型の空調装置５０で工場５２の内部５３を除湿するためには、内部５３の相対湿度の高い空気を工場５２の外部５４に排出し、外部５４から空気を矢印Ｅの如く取り入れる。
　空調装置５０で外部５４から取り入れる空気中から水分を好適に除去するためには、空調装置５０の電気消費量が嵩む。 Next, a usage example of the desiccant device 10 for dehumidification will be described with reference to FIGS. 8 (a) and 8 (b) and FIGS. 9 (a) and 9 (b).
As shown in FIG. 8A, in order to dehumidify the interior 53 of the factory 52 with the integrated air conditioner 50, the air having a high relative humidity in the interior 53 is discharged to the exterior 54 of the factory 52, and from the exterior 54 Intake air as shown by arrow E.
In order to suitably remove moisture from the air taken in from the outside 54 by the air conditioner 50, the electric consumption of the air conditioner 50 increases.
　図８（ｂ）に示すように、一体型の空調装置５０の上部５１に除湿用デシカント装置１０を後付することにより、除湿用デシカント装置１０に外部５４の空気を導く。よって、導いた空気中の水分を除湿用デシカント装置１０に吸着させて、空気中から水分を除去できる。これにより、相対湿度の低い乾燥空気を除湿用デシカント装置１０から空調装置５０の配管５６を経て工場５２の内部５３に送風できる。したがって、工場５２の内部５３の除湿を良好におこなうことができる。
　このように、空調装置５０に除湿用デシカント装置１０を後付することにより、電気消費量を抑えた状態で除湿機能を高めることができる。 As shown in FIG. 8B, the dehumidifying desiccant device 10 is retrofitted to the upper part 51 of the integrated air conditioner 50, thereby introducing the air in the outside 54 to the dehumidifying desiccant device 10. Therefore, the moisture in the introduced air can be adsorbed by the desiccant device 10 for dehumidification, and the moisture can be removed from the air. Thereby, dry air with a low relative humidity can be blown from the desiccant device 10 for dehumidification to the interior 53 of the factory 52 through the pipe 56 of the air conditioner 50. Therefore, the inside 53 of the factory 52 can be dehumidified well.
Thus, by attaching the desiccant device 10 for dehumidification to the air conditioner 50, it is possible to enhance the dehumidifying function while reducing the amount of electricity consumed.
　図９（ａ）に示すように、空調装置６０は、室外機６１と室内機６２とに分割されている。分割型の空調装置６０でも、一体型の空調装置５０と同様に、空調装置６０で外部５４から空気を矢印Ｆの如く取り入れる。
　空調装置６０で外部５４から取り入れる空気から水分を好適に除去するためには、空調装置６０の電気消費量が嵩む。 As shown in FIG. 9A, the air conditioner 60 is divided into an outdoor unit 61 and an indoor unit 62. Even in the split type air conditioner 60, as with the integrated type air conditioner 50, air is taken in from the outside 54 by the air conditioner 60 as indicated by an arrow F.
In order to suitably remove moisture from the air taken in from the outside 54 by the air conditioner 60, the amount of electricity consumed by the air conditioner 60 increases.
　図９（ｂ）に示すように、空調装置６０を室外機６１と室内機６２とに分割することにより、室外機６１、室内機６２は一体型の空調装置５０と比べて小さくなる。除湿用デシカント装置１０は小型に抑えられているので、たとえば、室内機６２の上部６３に除湿用デシカント装置１０を後付する領域を確保できる。これにより、除湿用デシカント装置１０の用途を広げることができる。 As shown in FIG. 9B, by dividing the air conditioner 60 into the outdoor unit 61 and the indoor unit 62, the outdoor unit 61 and the indoor unit 62 become smaller than the integrated air conditioner 50. Since the desiccant device 10 for dehumidification is kept small, for example, an area for retrofitting the desiccant device 10 for dehumidification can be secured on the upper part 63 of the indoor unit 62. Thereby, the use of the desiccant apparatus 10 for dehumidification can be expanded.
　分割型の空調装置６０の上部６３に除湿用デシカント装置１０を後付することにより、相対湿度の低い乾燥空気を除湿用デシカント装置１０から空調装置６０の配管６５を経て工場５２の内部５３に送風できる。これにより、空調装置６０に除湿用デシカント装置１０を後付するだけで一体型の空調装置５０と同様に、電気消費量を抑えた状態で除湿機能を高めることができる。 By attaching the desiccant desiccant device 10 to the upper part 63 of the split type air conditioner 60, dry air having a low relative humidity is blown from the desiccant device 10 for dehumidification to the interior 53 of the factory 52 through the piping 65 of the air conditioner 60. it can. Thereby, just by retrofitting the desiccant device 10 for dehumidification to the air conditioner 60, the dehumidification function can be enhanced in a state where the amount of electricity consumption is suppressed as in the case of the integrated air conditioner 50.
　なお、本発明の技術範囲は上述した実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることができる。
　前記実施形態では、除湿用デシカント装置１０として、第１デシカント１４、第２デシカント１６、第３デシカント１８を備えた例について説明したが、これに限定しない。その他の例として、第１デシカント１４、第２デシカント１６のみを備えることもできる。また、除湿用デシカント装置１０として３個以上のデシカントを備えることもできる。 The technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
In the embodiment, the example in which the desiccant device 10 for dehumidification includes the first desiccant 14, the second desiccant 16, and the third desiccant 18 has been described. However, the present invention is not limited to this. As another example, only the first desiccant 14 and the second desiccant 16 can be provided. In addition, the desiccant device 10 for dehumidification can include three or more desiccants.
　さらに、前記実施形態では、第１～第３のデシカント１４，１６，１８の各シート２１，３１，３４を渦巻き状に巻回することにより正面視円形に形成した例について説明したが、これに限定しない。その他の例として、第１～第３のデシカントをキューブ状（立方体状）に形成することもできる。
　この場合、たとえば、平坦なメッシュ（網目）間に除湿剤を挟み、平坦なメッシュを上下方向に空気が流れる間隔を空けて積層することによりデシカントが形成される。 Furthermore, in the above-described embodiment, an example in which the sheets 21, 31, 34 of the first to third desiccants 14, 16, 18 are spirally wound to form a circular shape in front view has been described. Not limited. As another example, the first to third desiccants can be formed in a cube shape (cube shape).
In this case, for example, the desiccant is formed by sandwiching a dehumidifying agent between flat meshes (mesh) and laminating the flat meshes with an interval in which air flows in the vertical direction.
　さらに、前記実施形態では、除湿用デシカント装置１０を流路１２の内部１３に固定させる例について説明したが、これに限定しない。その他の例として、除湿用デシカント装置１０を流路１２の内部１３に回転可能に設けることもできる。 Furthermore, in the said embodiment, although the example which fixes the desiccant apparatus 10 for dehumidification to the inside 13 of the flow path 12 was demonstrated, it is not limited to this. As another example, the desiccant device 10 for dehumidification can be rotatably provided in the inside 13 of the flow path 12.
　また、前記実施形態では、第１～第３のデシカント１４，１６，１８の各シート２１，３１，３４の内部に各微小除湿剤２４，３２，３５を保持する例について説明したが、これに限定しない。その他の例として、ケース内に除湿剤を移動自在に収容し、ケースに流路を連通させるように構成することもできる。ケース内に流路から空気を流すことにより、ケース内の除湿剤を空気で流動させ、ケース内の除湿剤に均等に空気を接触させることにより、空気中の水分を除湿剤で吸着できる。 In the embodiment, the example in which the minute dehumidifiers 24, 32, and 35 are held inside the sheets 21, 31, and 34 of the first to third desiccants 14, 16, and 18 has been described. Not limited. As another example, a dehumidifying agent can be movably accommodated in the case, and a flow path can be communicated with the case. By flowing air from the flow path into the case, the dehumidifying agent in the case is made to flow with air, and the moisture in the air can be adsorbed by the dehumidifying agent by making the air uniformly contact the dehumidifying agent in the case.
　さらに、前記実施形態では、第１～第３のスペーサ除湿剤２５，３７，３８がスペーサと除湿剤とを兼ねる例について説明したが、これに限定しない。その他の例として、第１～第３のスペーサ除湿剤２５，３７，３８をスペーサのみの部材に代えることも可能である。これにより、例えば、第１～第３のデシカント１４，１６，１８の設計の自由度を高めることができる。 Furthermore, although the first to third spacer dehumidifying agents 25, 37, and 38 serve as both a spacer and a dehumidifying agent have been described in the above embodiment, the present invention is not limited to this. As another example, the first to third spacer dehumidifiers 25, 37, and 38 can be replaced with members having only spacers.
