Description

本発明は、空間内の湿度を上下に制御せしめ得る調湿装置及び調湿方法に関し、特に、空間内の温度を変化させることなく調湿を与え得る調湿装置及び調湿方法に関する。 The present invention relates to a humidity control device and a humidity control method that can control the humidity in a space up and down, and more particularly to a humidity control device and a humidity control method that can give humidity control without changing the temperature in the space.

居住空間の如きを除湿し及び加湿をするための調湿装置（湿度制御器）が知られている。空間容積が大きくなり、調湿による変化させるべき水分量が大きくなると、装置規模も大きくなる。一方、比較的容積の小さい空間を除湿し及び加湿をするための小型の調湿装置も提案されている。 A humidity control device (humidity controller) for dehumidifying and humidifying a living space is known. As the space volume increases and the amount of water to be changed by humidity control increases, the scale of the device also increases. On the other hand, a small humidity control device for dehumidifying and humidifying a space having a relatively small volume has also been proposed.

例えば、特許文献１では、このような小型の調湿装置として、冷却時に空気中の水分を吸収し且つ加熱時に吸収した水分を空気中に発散する高分子吸収体を用いて、この高分子吸収体をペルチェ素子の上に設けて湿度を制御する調湿装置を開示している。湿度センサの検出値に応じてコントローラがペルチェ素子の通電状態を制御し高分子吸収体内の水分量を変化させてその外部の調湿を行う。かかる高分子吸収体としては、アクリル系のポリアクリル酸ナトリウム架橋体を１例として挙げ、イオン性の基を有する水溶性の電解質ポリマーに軽度の架橋結合を導入した３次元網目構造を備えてなる天然高分子類や合成高分子類からなる層状成形物を用い得るとしている。 For example, in Patent Document 1, as such a small humidity control device, a polymer absorber that absorbs moisture in the air during cooling and dissipates the moisture absorbed during heating into the air is used to absorb the polymer. A humidity control device for controlling humidity by providing a body on a Pelche element is disclosed. The controller controls the energized state of the Pelche element according to the detection value of the humidity sensor, changes the amount of water in the polymer absorbing body, and adjusts the humidity outside it. As an example of such a polymer absorber, an acrylic-based sodium polyacrylate crosslinked product is taken as an example, and is provided with a three-dimensional network structure in which a mild crosslinked bond is introduced into a water-soluble electrolyte polymer having an ionic group. It is said that a layered molded product made of natural polymers or synthetic polymers can be used.

また、特許文献２では、吸湿性を有する吸湿剤をエキスパンドメタルの表面に層状に形成し、この吸湿剤層に水分を吸着させる時はエキスパンドメタルに非通電とし、吸湿剤層から水分を脱離させる時はエキスパンドメタルに通電する調湿装置を開示している。吸湿剤層は無機材料からなり、少なくともゼオライト、シリカゲル、アルミナのいずれか１種以上を用いている。吸湿を冷却によらないため、ペルチェ素子の如き特別な通電素子を用いずとも調湿装置を与え得るとしている。 Further, in Patent Document 2, a hygroscopic agent having a hygroscopic property is formed in a layer on the surface of the expanded metal, and when the moisture is adsorbed on the hygroscopic layer, the expanded metal is de-energized to desorb the moisture from the hygroscopic layer. A humidity control device that energizes the expanded metal is disclosed. The hygroscopic layer is made of an inorganic material, and at least one of zeolite, silica gel, and alumina is used. Since the moisture absorption does not depend on cooling, it is possible to provide a humidity control device without using a special energizing element such as a Pelche element.

更に、特許文献３では、セルロースを主成分とする繊維からなる基材部の外表面に導電性材料を与えた調湿素子を開示している。該導電性材料に非通電状態において、該導電性材料及び基材部によって空間の水分を吸着し、通電状態において、吸着している水分を基材部から該導電性材料を介して空間に放出する。かかる導電性材料としては、導電性高分子等を挙げているが、特に、チオフェン系導電性高分子であるＰＥＤＯＴ／ＰＳＳ（ポリ（３，４－エチレンジオキシチオフェン）－ポリ（スチレンスルホン酸））が放出する水分の粒径を小さくできて好ましいとしている。 Further, Patent Document 3 discloses a humidity control element in which a conductive material is applied to the outer surface of a base material portion made of a fiber containing cellulose as a main component. Moisture in the space is adsorbed by the conductive material and the base material portion in the non-energized state of the conductive material, and the adsorbed moisture is released from the base material portion into the space through the conductive material in the energized state. do. Examples of such conductive materials include conductive polymers, and in particular, PEDOT / PSS (poly (3,4-ethylenedioxythiophene) -poly (styrene sulfonic acid), which is a thiophene-based conductive polymer. ) Can reduce the particle size of the water released, which is preferable.

吸水性と導電性とを兼ね備える導電性高分子材料を閉空間に配置し、この高分子材料を通電加熱させて、可逆的に水分を吸着及び放出させて調湿装置を得ることができる。一方、高分子材料の通電加熱により閉空間の温度も上昇し、場合によっては、閉空間の飽和水蒸気量を変化させてしまうこともある。 A conductive polymer material having both water absorption and conductivity is arranged in a closed space, and the polymer material is energized and heated to reversibly adsorb and release water to obtain a humidity control device. On the other hand, the temperature of the closed space also rises due to the energization heating of the polymer material, and in some cases, the amount of saturated water vapor in the closed space may change.

本発明は、かかる状況に鑑みてなされたものであって、その目的とするところは、空間内の温度を変化させることなく調湿を与え得る調湿装置、及び調湿方法を提供することにある。 The present invention has been made in view of such a situation, and an object of the present invention is to provide a humidity control device and a humidity control method capable of giving humidity control without changing the temperature in a space. be.

本願発明者は、吸水性を有する導電性高分子からなる帯状シート体に可逆的に水分を吸着及び放出させるにあたって、効率のよい通電加熱をすることで、空間内の温度を変化させることなく調湿を与え得る調湿装置、及び内部温度の変化の小さい調湿ケースを提供できるのではないかと考えて本発明に到った。 The inventor of the present application adjusts the temperature in the space without changing the temperature by efficiently energizing and heating the strip-shaped sheet body made of a conductive polymer having water absorption to reversibly adsorb and release water. We came up with the present invention with the idea that we could provide a humidity control device that can give moisture and a humidity control case with a small change in internal temperature.

以下、本発明の１つの実施例である調湿装置及びその調湿方法について、図に沿ってその詳細を説明する。 Hereinafter, the details of the humidity control device and the humidity control method thereof, which are one embodiment of the present invention, will be described with reference to the drawings.

図１に示すように、調湿ケース２０は、内部を閉空間とできるケース体２１と、ケース体２１内部の湿度を測定できる湿度測定部２２と、ケース体２１の内部に備えられる調湿装置１０と、調湿装置１０に電流を付与できる電源部２３とを含む。電源部２３は、湿度測定部２２に接続されており、測定された湿度に応じて調湿装置１０に付与する電流値を制御できる。内部を閉空間とできるケース体２１としては、例えばデシケータなどが挙げられる。 As shown in FIG. 1, the humidity control case 20 includes a case body 21 having a closed space inside, a humidity measuring unit 22 capable of measuring the humidity inside the case body 21, and a humidity control device provided inside the case body 21. 10 and a power supply unit 23 capable of applying a current to the humidity control device 10. The power supply unit 23 is connected to the humidity measuring unit 22, and can control the current value applied to the humidity control device 10 according to the measured humidity. Examples of the case body 21 having a closed space inside include a desiccator.

図２に示すように、調湿装置１０は、両主面から水分を可逆的に放出及び吸収させ得る帯状の膜体であるシート体１と、シート体１に通電させて加熱するための電極２とを含む、シート体１は、吸水性を有するフリースタンディング膜であり、その両主面を周囲に曝すよう電極２によって支持されるとよい。電極２は、電源部２３に接続される。また、電極２は、シート体１の全体に一様なジュール熱を発生させ得るよう、シート体１の長手方向両端部において、シート体１の全幅に亘って接続されていることが好ましい。 As shown in FIG. 2, the humidity control device 10 includes a sheet body 1 which is a band-shaped film body capable of reversibly releasing and absorbing water from both main surfaces, and electrodes for energizing and heating the sheet body 1. The sheet body 1 including 2 is a free standing film having water absorption, and it is preferable that the sheet body 1 is supported by the electrode 2 so as to expose both main surfaces thereof to the surroundings. The electrode 2 is connected to the power supply unit 23. Further, it is preferable that the electrodes 2 are connected over the entire width of the sheet body 1 at both ends in the longitudinal direction of the sheet body 1 so that uniform Joule heat can be generated in the entire sheet body 1.

シート体１は、チオフェン系の導電性高分子に有機溶媒、特に、エチレングリコール（ＥＧ）を添加し導電性を高めたものであり、乾燥重量に対して３０％以上の水を吸収することの可能な膜厚さを有する。また、チオフェン系導電性高分子としては、ＰＥＤＯＴ／ＰＳＳ（ポリ（３，４－エチレンジオキシチオフェン）／ポリ（４－スチレンスルホン酸））を用いると、水分の放出及び吸収に対して効率よく通電加熱できて好ましい。また、ＥＧの添加によってシート体１はチオフェン系導電性高分子の可逆的な給水（吸湿）性を失わせることなく電気伝導度を高められて、通電加熱の温度を高めずとも水分の蒸散量を多くするような制御が容易となる。つまり、周囲の温度変化をごくわずかに抑えつつ水分の放出を可能とするような効率のよい通電加熱制御が容易である。つまり、通電加熱による熱のより多くを水分の放出に用い効率のよい制御とするのである。なお、チオフェン系導電性高分子の電気伝導度を高めるために、ＥＧ以外にも、ジメチルスルホキシド（ＤＭＳＯ）などの高沸点溶媒を添加してもよい。 The sheet body 1 is made by adding an organic solvent, particularly ethylene glycol (EG), to a thiophene-based conductive polymer to enhance the conductivity, and absorbs 30% or more of water with respect to the dry weight. Has a possible film thickness. Further, when PEDOT / PSS (poly (3,4-ethylenedioxythiophene) / poly (4-styrenesulfonic acid)) is used as the thiophene-based conductive polymer, it is efficient for the release and absorption of water. It is preferable to be able to energize and heat. Further, by adding EG, the electric conductivity of the sheet body 1 can be increased without losing the reversible water supply (hygroscopicity) property of the thiophene-based conductive polymer, and the amount of water evaporation without increasing the temperature of energization heating. It becomes easy to control to increase the number of. That is, it is easy to efficiently control the energization heating so as to enable the release of water while suppressing the change in the ambient temperature very slightly. In other words, more of the heat generated by energization heating is used for the release of water for efficient control. In addition to EG, a high boiling point solvent such as dimethyl sulfoxide (DMSO) may be added in order to increase the electrical conductivity of the thiophene-based conductive polymer.

また、シート体１は、導電性高分子、特に、チオフェン系の導電性高分子の電気伝導度をＥＧなどで高めるように調整され、さらにその厚さ、幅及び長さを調整されることで全体の抵抗を調整される。これによって、シート体１への通電加熱と水分の放出とをバランスさせて、温度を高めずに水分の蒸散量を多くするような通電制御、特に、電流制御を容易とする。 Further, the sheet body 1 is adjusted so as to increase the electric conductivity of the conductive polymer, particularly the thiophene-based conductive polymer by EG or the like, and further adjusts the thickness, width and length thereof. The overall resistance is adjusted. This facilitates energization control, particularly current control, in which the energization heating to the sheet body 1 and the release of water are balanced to increase the amount of water evaporation without increasing the temperature.

このような調湿装置１０によれば、シート体１に通電することでシート体１の両主面から水分を空間に放出させるとともに、通電を停止してシート体１に空間内の水分を吸収させることができる。そのため、シート体１の両主面を空間に露出さえることが好ましい。これにより、通電の制御によって調湿装置１０の設置された空間内の温度を変化させずに、飽和水蒸気量を変化させることなく調湿を可能とする。つまり、調湿ケース２０においては、ケース体２１の内部空間の温度変化を小さくしつつ内部空間の調湿を可能とするのである。 According to such a humidity control device 10, by energizing the sheet body 1, moisture is released into the space from both main surfaces of the sheet body 1, and the energization is stopped to allow the sheet body 1 to absorb the moisture in the space. Can be made to. Therefore, it is preferable to expose both main surfaces of the sheet body 1 to the space. As a result, humidity control is possible without changing the temperature in the space where the humidity control device 10 is installed by controlling the energization, and without changing the saturated water vapor amount. That is, in the humidity control case 20, it is possible to control the humidity of the internal space while reducing the temperature change in the internal space of the case body 21.

特に、シート体１は表面温度を５℃以内で通電制御、通常、電流制御されて重量比で３０％以上の水を放出及び吸収する膜厚さとされることが好ましく、これによって調湿装置１０の設置された空間内の温度を変化させることなく調湿することがより容易となる。また、シート体１は両主面から水分の放出及び吸収を可能とするよう、例えばフリースタンディング膜とすることで水分の放出量を多くでき、これによっても空間の温度変化を小さくできる。 In particular, the sheet body 1 preferably has a surface temperature controlled by energization within 5 ° C. and usually controlled by an electric current to have a film thickness of 30% or more by weight to release and absorb water, whereby the humidity control device 10 is used. It becomes easier to control the humidity without changing the temperature in the space where the is installed. Further, the sheet body 1 can increase the amount of water released by using, for example, a free standing film so as to enable the release and absorption of water from both main surfaces, and this also makes it possible to reduce the temperature change in the space.

［実施例］
上記したチオフェン系導電性高分子によるシート体１を用いて各種調査を行った結果について説明する。[Example]
The results of various investigations using the sheet body 1 made of the above-mentioned thiophene-based conductive polymer will be described.

図３に示すように、ＰＥＤＯＴ／ＰＳＳによるシート体１を空間中に曝すと、最大で１．３０倍以上の重量になった。ＰＥＤＯＴ／ＰＳＳの重量の増加は水分によるものであるから、シート体１は乾燥重量に対して３０％以上の水を吸収し得ることが判る。 As shown in FIG. 3, when the sheet body 1 by PEDOT / PSS was exposed to the space, the weight became 1.30 times or more at the maximum. Since the increase in the weight of PEDOT / PSS is due to water content, it can be seen that the sheet body 1 can absorb 30% or more of water with respect to the dry weight.

図４に示すように、ＰＥＤＯＴ／ＰＳＳにＥＧを添加すると、その電気伝導度は添加前の数Ｓ／ｃｍに比べて１００～１０００倍程度（２～３桁）まで高くなり、このような調湿に使用するにあたって、少なくとも、３００Ｓ／ｃｍ、好ましくは、５００Ｓ／ｃｍ以上であり、典型的には、６００～１０００Ｓ／ｃｍとされる。つまり、ＥＧの添加によってＰＥＤＯＴ／ＰＳＳの電気伝導度を高くするとともにその値をＥＧの添加量によって制御できて、効率の良い通電加熱をより容易とし得る。なお、ＥＧの添加によるＰＥＤＯＴ／ＰＳＳの電気伝導度の増大は、その結晶構造の規則性の増大によるものであることが、Ｘ線結晶構造解析によりわかっている。 As shown in FIG. 4, when EG is added to PEDOT / PSS, its electrical conductivity increases to about 100 to 1000 times (2 to 3 digits) higher than the number S / cm before the addition, and such an adjustment is made. For wet use, it is at least 300 S / cm, preferably 500 S / cm or more, typically 600-1000 S / cm. That is, the electric conductivity of PEDOT / PSS can be increased by adding EG, and the value can be controlled by the amount of EG added, so that efficient energization heating can be facilitated. It is known from X-ray crystal structure analysis that the increase in the electrical conductivity of PEDOT / PSS due to the addition of EG is due to the increase in the regularity of the crystal structure.

図５に示すように、ＥＧを添加したＰＥＤＯＴ／ＰＳＳをシート体１に電流を付与したところ、水分を放出又は吸収してその重量を変化させた。使用したシート体１は、５０ｍｍ×２６ｍｍ×５０μｍの帯状膜であり、乾燥重量は１００ｍｇ、電極間の抵抗値は５．４Ω（電気伝導度は８００Ｓ／ｃｍ）であった。シート体１は、付与する電流値を増大させることで水分を放出して重量を減少させ、電流値を減少させることで水分を吸収して重量を増加させて元に戻ることが判る。 As shown in FIG. 5, when an electric current was applied to the sheet body 1 of PEDOT / PSS to which EG was added, water was released or absorbed to change the weight thereof. The sheet body 1 used was a strip-shaped film having a size of 50 mm × 26 mm × 50 μm, a dry weight of 100 mg, and a resistance value between electrodes of 5.4 Ω (electrical conductivity was 800 S / cm). It can be seen that the sheet body 1 releases water to reduce the weight by increasing the applied current value, and absorbs water to increase the weight by decreasing the current value to return to the original state.

図６に示すように、このシート体１を０．５Ｌの閉空間を有する容器内に配置して、シート体１に電流を付与しながら容器内の温度と湿度を測定した。電流値を変化させるだけで容器内の温度をほとんど変化させずに相対湿度を２０～９０％の広範囲で制御できた。 As shown in FIG. 6, the sheet body 1 was placed in a container having a closed space of 0.5 L, and the temperature and humidity in the container were measured while applying a current to the sheet body 1. Relative humidity could be controlled in a wide range of 20 to 90% by changing the current value and hardly changing the temperature inside the container.

以上のように、ＥＧを添加したチオフェン系導電性高分子による吸水性膜であるシート体１を用いた調湿装置１０によれば、シート体１に通電することで、空間内の温度を変化させることなく調湿できるのである。 As described above, according to the humidity control device 10 using the sheet body 1 which is a water-absorbent film made of a thiophene-based conductive polymer to which EG is added, the temperature in the space is changed by energizing the sheet body 1. Humidity can be controlled without causing it.
