On the other hand, since superheated steam having a temperature of 160 ° C. or higher has extremely excellent diffusivity, the demerit of the latter outweighs the merit of the former, and it is presumed that strong ventilation rather promotes the bias of temperature and humidity.

　以下、本発明の実施形態について詳細に説明する。なお、本発明は以下の実施形態に限定されない。 Hereinafter, embodiments of the present invention will be described in detail. The present invention is not limited to the following embodiments.
＜加湿装置＞
　本発明の加湿装置は、過熱水蒸気を発生する過熱水蒸気発生手段と、該過熱水蒸気発生手段から発生した過熱水蒸気を空間へと供給する過熱水蒸気供給手段と、を備え、かつ、１６０℃以上の過熱水蒸気を風量２．５ｍ３／分以下の条件下で空間へ供給することにより加湿するものである。 <Humidifier>
The humidifying device of the present invention includes a superheated steam generating means for generating superheated steam and a superheated steam supplying means for supplying the superheated steam generated from the superheated steam generating means to a space, and superheats at 160 ° C. or higher. It humidifies by supplying water vapor to the space under the condition of air volume of 2.5 m 3 / min or less.
　本発明の加湿装置は、１６０℃以上の過熱水蒸気を風量２．５ｍ３／分以下の条件下で空間へ供給する点以外は、従来知られる加湿装置と同様の構成を採用し得る。 The humidifying device of the present invention can adopt the same configuration as the conventionally known humidifying device except that superheated steam of 160 ° C. or higher is supplied to the space under the condition of an air volume of 2.5 m 3 / min or less.
　過熱水蒸気を室内へ供給することで加湿を行う技術は従来知られるものである。
　しかし、本発明者の検討の結果、意外にも、室内への過熱水蒸気供給を、風量の多い条件下で供給を行うと、空間の湿度及び温度の少なくとも一方の偏りが増加してしまうことを見出した。 The technique of humidifying by supplying superheated steam to a room is conventionally known.
However, as a result of the study of the present inventor, surprisingly, when the superheated steam is supplied to the room under the condition of a large air volume, the bias of at least one of the humidity and the temperature of the space increases. I found it.
　本発明者によるさらなる検討の結果、室内への過熱水蒸気供給を、低風量条件下又は無風条件下、すなわち、風量２．５ｍ３／分以下の条件下で行うと、空間の湿度及び温度の偏りを抑制でき、室内環境の快適性等が均一になり得ること、加湿装置の運転効率が高まったり、室内で埃がたちにくかったりすることを見出した。加えて、後述のように視覚的に確認容易な現象が生じず、装置稼働がユーザの注意を過剰にひきつけないことも相まって、本発明の加湿装置は、長時間にわたって稼働させ続けることが好ましく、それにより、不利益なく高い快適性の空間を常時提供することができる。 As a result of further studies by the present inventor, when the superheated steam is supplied to the room under low air volume conditions or no wind conditions, that is, under conditions where the air volume is 2.5 m 3 / min or less, the humidity and temperature of the space are biased. It has been found that the temperature can be suppressed, the comfort of the indoor environment can be made uniform, the operating efficiency of the humidifying device can be improved, and the dust can be hard to get in the room. In addition, it is preferable that the humidifying device of the present invention is continuously operated for a long period of time, because the phenomenon that is easily visually confirmed does not occur as described later and the device operation does not attract the user's attention excessively. As a result, it is possible to always provide a highly comfortable space without any disadvantage.
　１６０℃以上の過熱水蒸気は、大きい運動エネルギーを持ち拡散性に優れ、かつ十分に温度が高い。
　そのため、このような過熱水蒸気は、加湿装置の近傍に高密度に滞留する間に空冷されにくく、相対湿度１００％を超えて霧（湯気）へと変化してしまう現象を回避して、気体のまま空間へと拡散することができる。つまり、本発明の一実施形態では、霧のような視認可能な物質が発生しないため、視覚的に確認容易な現象が生じない。
　さらに、気体として空間に拡散した水蒸気は、顕熱とともに、液体に変化する過程で潜熱を空間に放出することができ、高い加温効果も有する。
　上記のような作用で、本発明は湿度及び温度の双方の偏りを抑制することができる。
　また、本発明の一実施形態では、高い拡散性によって空間中の空気の対流を促進し、当該空気が、発生したての高温の過熱水蒸気に接触される頻度が増す。これにより、空間内の空気中のウイルスや病原菌を殺す効果も期待することができる。 Superheated steam of 160 ° C. or higher has a large kinetic energy, excellent diffusivity, and a sufficiently high temperature.
Therefore, such superheated steam is difficult to be air-cooled while staying in the vicinity of the humidifying device at high density, and avoids the phenomenon that the relative humidity exceeds 100% and changes to mist (steam), and the gas. It can diffuse into the space as it is. That is, in one embodiment of the present invention, a visible substance such as fog is not generated, so that a phenomenon that is visually easy to confirm does not occur.
Further, the water vapor diffused in the space as a gas can release latent heat into the space in the process of changing to a liquid together with sensible heat, and has a high heating effect.
With the above-mentioned action, the present invention can suppress the bias of both humidity and temperature.
Further, in one embodiment of the present invention, the high diffusivity promotes convection of air in the space, and the frequency of contact of the air with the newly generated high-temperature superheated steam increases. This can also be expected to have the effect of killing viruses and pathogens in the air in the space.
　なお、過熱水蒸気を高風量下（例えば、風量２．５ｍ３／分超）で送風すると、加湿装置近傍の雰囲気が別の場所へと速やかに移行するメリットがあるものの、過熱水蒸気の拡散は妨げられるというデメリットがある。
　他方で、１６０℃以上の過熱水蒸気は、極めて優れた拡散性を持つため、後者のデメリットが前者のメリットを上回り、強い送風は、温度及び湿度の偏りをむしろ助長するものと推測される。 If the superheated steam is blown under a high air volume (for example, an air volume of more than 2.5 m 3 / min), there is an advantage that the atmosphere near the humidifier is quickly transferred to another place, but the diffusion of the superheated steam is hindered. There is a demerit that it can be done.
On the other hand, since superheated steam having a temperature of 160 ° C. or higher has extremely excellent diffusivity, the demerit of the latter outweighs the merit of the former, and it is presumed that strong ventilation rather promotes the bias of temperature and humidity.
　本発明において「空間内の湿度の偏り」とは、測定時点、過熱水蒸気の温度条件、及び風量条件が同一である、異なる地点の湿度の偏差と、該測定時点から所定時間（例えば６０分）経過した後の同様の偏差との差によって評価することができ、例えば実施例に示した方法で特定される。
　本発明において「空間内の湿度の偏りが抑制されている」とは、上記偏差の差がより大きくなることであってよい。 In the present invention, the "humidity deviation in space" means the deviation of humidity at different points where the temperature condition of superheated steam and the air volume condition are the same at the time of measurement, and a predetermined time (for example, 60 minutes) from the time of measurement. It can be evaluated by the difference from the similar deviation after the lapse, and is specified by the method shown in the examples, for example.
In the present invention, "the bias of humidity in the space is suppressed" may mean that the difference in the deviations becomes larger.
　本発明において「空間内の温度の偏り」とは、測定時点、過熱水蒸気の温度条件、及び風量条件が同一である、異なる地点の温度の偏差と、該測定時点から所定時間（例えば６０分）経過した後の同様の偏差との差によって評価することができ、例えば実施例に示した方法で特定される。
　本発明において「空間内の温度の偏りが抑制されている」とは、上記偏差の差がより大きくなることであってよい。 In the present invention, "temperature deviation in space" means a deviation in temperature at different points where the temperature condition of the superheated steam and the air volume condition are the same, and a predetermined time (for example, 60 minutes) from the measurement time. It can be evaluated by the difference from the similar deviation after the lapse, and is specified by the method shown in the examples, for example.
In the present invention, "the temperature bias in the space is suppressed" may mean that the difference in the deviations becomes larger.
　以下、本発明の加湿装置の構成について詳述する。 Hereinafter, the configuration of the humidifying device of the present invention will be described in detail.
（過熱水蒸気発生手段）
　過熱水蒸気発生手段とは、過熱水蒸気を発生させることができる手段である。 (Means for generating superheated steam)
The superheated steam generating means is a means capable of generating superheated steam.
　通常、過熱水蒸気発生手段は、加湿装置内に供給された水を任意の温度に加熱するために要する機能（タンク、ヒーター、ボイラー、加熱温度調整手段等）を備える。 Normally, the superheated steam generating means has a function (tank, heater, boiler, heating temperature adjusting means, etc.) required to heat the water supplied into the humidifying device to an arbitrary temperature.
　本発明において「過熱水蒸気」とは、所定の圧力下における沸点で蒸発した状態の水蒸気、すなわち飽和水蒸気を、同圧力下で沸点を超える温度で加熱した水蒸気を意味する。 In the present invention, "superheated steam" means steam in a state of being evaporated at a boiling point under a predetermined pressure, that is, steam obtained by heating saturated steam at a temperature exceeding the boiling point under the same pressure.
　過熱水蒸気発生手段によって発生した過熱水蒸気の温度は、後述する過熱水蒸気供給手段から空間へ放出された時点で１６０℃以上となるように設定される。
　ただし、過熱水蒸気が過熱水蒸気発生手段から過熱水蒸気供給手段に移行する際に、過熱水蒸気の温度が下がる可能性があるため、過熱水蒸気供給手段から放出された過熱水蒸気の温度が、過熱水蒸気発生手段によって発生した過熱水蒸気の温度よりも低くなり得る。
　そのため、過熱水蒸気供給手段から放出される過熱水蒸気の温度を確実に１６０℃以上に調整するために、過熱水蒸気発生手段における加熱温度を、過熱水蒸気供給手段から放出しようとする過熱水蒸気の温度よりも高く（例えば、５０～２００℃高く）設定してもよい。 The temperature of the superheated steam generated by the superheated steam generating means is set to be 160 ° C. or higher when it is discharged into the space from the superheated steam supply means described later.
However, when the superheated steam shifts from the superheated steam generating means to the superheated steam supplying means, the temperature of the superheated steam may drop. Therefore, the temperature of the superheated steam released from the superheated steam supplying means is the temperature of the superheated steam generating means. It can be lower than the temperature of the superheated steam generated by.
Therefore, in order to surely adjust the temperature of the superheated steam discharged from the superheated steam supply means to 160 ° C. or higher, the heating temperature in the superheated steam generating means is higher than the temperature of the superheated steam to be discharged from the superheated steam supply means. It may be set high (for example, 50 to 200 ° C. high).
　過熱水蒸気の温度が高いほど本発明の効果が奏されやすい傾向にあるため、過熱水蒸気発生手段によって発生した過熱水蒸気の温度の下限値は、好ましくは２１０℃以上、より好ましくは２７０℃以上である。 Since the effect of the present invention tends to be more likely to be exhibited as the temperature of the superheated steam is higher, the lower limit of the temperature of the superheated steam generated by the superheated steam generating means is preferably 210 ° C. or higher, more preferably 270 ° C. or higher. ..
　過熱水蒸気発生手段によって発生した過熱水蒸気の温度の上限値は特に限定されないが、適度な温湿度を実現しやすいという観点から、好ましくは６００℃以下、より好ましくは５００℃以下である。 The upper limit of the temperature of the superheated steam generated by the superheated steam generating means is not particularly limited, but is preferably 600 ° C. or lower, more preferably 500 ° C. or lower, from the viewpoint of easily realizing an appropriate temperature and humidity.
（過熱水蒸気供給手段）
　過熱水蒸気供給手段は、過熱水蒸気発生手段から発生した過熱水蒸気を空間へと供給することができる手段である。 (Superheated steam supply means)
The superheated steam supply means is a means capable of supplying the superheated steam generated from the superheated steam generating means to the space.
　通常、過熱水蒸気供給手段は、過熱水蒸気を、過熱水蒸気発生手段から加湿装置外の空間へ導くための手段（ダクト、送風ファン、過熱水蒸気の供給量調整手段等）を備える。 Normally, the superheated steam supply means is provided with means (duct, blower fan, superheated steam supply amount adjusting means, etc.) for guiding the superheated steam from the superheated steam generating means to the space outside the humidifying device.
　過熱水蒸気供給手段を介して空間へ供給された過熱水蒸気の温度は、過熱水蒸気供給手段から放出された時点で１６０℃以上である。 The temperature of the superheated steam supplied to the space via the superheated steam supply means is 160 ° C. or higher when it is released from the superheated steam supply means.
　過熱水蒸気供給手段を介して空間へ供給された過熱水蒸気の温度の下限値は、好ましくは１６５℃以上、より好ましくは２２０℃以上である。 The lower limit of the temperature of the superheated steam supplied to the space via the superheated steam supply means is preferably 165 ° C. or higher, more preferably 220 ° C. or higher.
　過熱水蒸気供給手段を介して空間へ供給された過熱水蒸気の温度の上限値は特に限定されないが、好ましくは４００℃以下、より好ましくは３００℃以下である。 The upper limit of the temperature of the superheated steam supplied to the space via the superheated steam supply means is not particularly limited, but is preferably 400 ° C. or lower, more preferably 300 ° C. or lower.
（過熱水蒸気の供給条件）
　上記のように過熱水蒸気供給手段を介して空間へ供給された１６０℃以上の過熱水蒸気は、風量２．５ｍ３／分以下の条件下で空間へ供給される。
　このように過熱水蒸気を空間へ供給することにより、空間内の湿度及び温度の偏りを抑制しつつ、室内を加湿することができる。 (Supply conditions for superheated steam)
The superheated steam of 160 ° C. or higher supplied to the space via the superheated steam supply means as described above is supplied to the space under the condition of an air volume of 2.5 m 3 / min or less.
By supplying superheated steam to the space in this way, it is possible to humidify the room while suppressing the unevenness of humidity and temperature in the space.
　本発明において「室内を加湿する」とは、本発明の加湿装置を稼働させることにより、稼働前の湿度（通常、相対湿度）が増加することを意味する。 In the present invention, "humidifying the room" means that the humidity (usually, relative humidity) before the operation is increased by operating the humidifying device of the present invention.
　過熱水蒸気を、風量２．５ｍ３／分以下の条件下で空間へ供給する方法としては特に限定されない。 The method of supplying superheated steam to the space under the condition of an air volume of 2.5 m 3 / min or less is not particularly limited.
　過熱水蒸気を、風量２．５ｍ３／分以下の条件下で空間へ供給する方法の一例として、本発明の加湿装置を無風環境下（風量０ｍ３／分の条件）に置いた状態で稼働させ、過熱水蒸気を空間へ供給する方法が挙げられる。 As an example of a method of supplying superheated steam to a space under a condition of an air volume of 2.5 m 3 / min or less, the humidifier of the present invention is operated in a windless environment (condition of an air volume of 0 m 3 / min). , A method of supplying superheated steam to the space can be mentioned.
　過熱水蒸気を、風量２．５ｍ３／分以下の条件下で空間へ供給する方法の一例として、本発明の加湿装置と、過熱水蒸気を送風する送風手段を併置し、加湿装置から空間へ供給される過熱水蒸気の周囲の風量条件を風量２．５ｍ３／分以下となるように調整する方法が挙げられる。該送風手段は、送風手段の送風量を風量２．５ｍ３／分以下の範囲内で調節する風量調節手段を備える。
　かかる場合、過熱水蒸気を送風する送風手段は、本発明の加湿装置に内蔵されたものでもよく、本発明の加湿装置とは別個の装置（エアサーキュレーター等）でもよい。 As an example of a method of supplying superheated steam to a space under a condition of an air volume of 2.5 m 3 / min or less, the humidifier of the present invention and a ventilation means for blowing superheated steam are juxtaposed and supplied from the humidifier to the space. A method of adjusting the air volume condition around the superheated steam so that the air volume is 2.5 m 3 / min or less can be mentioned. The blowing means includes an air volume adjusting means for adjusting the blowing volume of the blowing means within a range of an air volume of 2.5 m 3 / min or less.
In such a case, the ventilation means for blowing the superheated steam may be one built in the humidifying device of the present invention, or may be a device (air circulator or the like) separate from the humidifying device of the present invention.
　過熱水蒸気供給手段を介して空間へ供給された過熱水蒸気は、好ましくは風量２．３０ｍ３／分以下、より好ましくは風量１．２０ｍ３／分以下、さらに好ましくは０．６０ｍ３／分以下、最も好ましくは風量０ｍ３／分（すなわち無風）の条件下で空間へ供給される。 The superheated steam supplied to the space via the superheated steam supply means preferably has an air volume of 2.30 m 3 / min or less, more preferably an air volume of 1.20 m 3 / min or less, and further preferably 0.60 m 3 / min or less. Most preferably, it is supplied to the space under the condition of an air volume of 0 m 3 / min (that is, no wind).
　本発明の好ましい態様において、本発明の加湿装置は過熱水蒸気を送風する送風手段を備えない。 In a preferred embodiment of the present invention, the humidifying device of the present invention does not include a ventilation means for blowing superheated steam.
（その他の手段）
　本発明の加湿装置は上記手段を備えていればよいが、必要に応じてさらなる手段を備えていてもよい。このような手段としては、従来知られる加湿装置が備える各種手段を用いることができる。 (Other means)
The humidifying device of the present invention may be provided with the above means, but may be provided with further means as needed. As such means, various means provided in a conventionally known humidifying device can be used.
＜加湿された空間の作成方法＞
　上記のとおり、本発明においては、１６０℃以上の過熱水蒸気を風量２．５ｍ３／分以下の条件下で空間へ供給する工程により、温度及び湿度の偏りを抑制できる。
　したがって、本発明は、該工程を含む加湿された空間の作成方法も包含する。 <How to create a humidified space>
As described above, in the present invention, the bias of temperature and humidity can be suppressed by the step of supplying superheated steam of 160 ° C. or higher to the space under the condition of air volume of 2.5 m 3 / min or less.
Therefore, the present invention also includes a method of creating a humidified space including the step.
＜空間内における結露の抑制方法＞
　上記のとおり、本発明においては、１６０℃以上の過熱水蒸気を風量２．５ｍ３／分以下の条件下で空間へ供給する工程により、温度及び湿度の偏りを抑制できる。
　上記工程によって温度及び湿度の偏りが抑制された空間内で、空間内の相対湿度をモニタリングし、かつ、相対湿度の値に応じて加湿装置からの過熱水蒸気の供給条件を適宜調整することで、空間内における結露を効果的に抑制できる。 <Method of suppressing dew condensation in space>
As described above, in the present invention, the bias of temperature and humidity can be suppressed by the step of supplying superheated steam of 160 ° C. or higher to the space under the condition of air volume of 2.5 m 3 / min or less.
By monitoring the relative humidity in the space and adjusting the supply conditions of superheated steam from the humidifier according to the value of the relative humidity in the space where the deviation of temperature and humidity is suppressed by the above process. Condensation in the space can be effectively suppressed.
　従来の技術では、加湿装置近傍の温度及び湿度の少なくとも一方と、結露が生じる場所（窓近傍等）における温度及び湿度の少なくとも一方との間の差が大きく、加湿器近傍の温度及び湿度に基づいて加湿条件を制御しても、窓近傍では相対湿度が１００％を超え、結露を予防することが困難だった。
　これに対し、本発明により温度及び湿度の偏りが抑制された空間内においては、加湿装置近傍の温度及び湿度の双方と、結露が生じる場所（窓近傍等）における温度及び湿度の双方との間の差が小さいため、結露が生じる場所における相対湿度をより正確に予測でき、結露が生じないように加湿条件を調整できる。
　したがって、本発明は、空間内における結露の抑制方法（以下、「本発明の結露抑制方法」ともいう。）も包含する。 In the conventional technique, the difference between at least one of the temperature and humidity in the vicinity of the humidifier and at least one of the temperature and humidity in the place where dew condensation occurs (near the window, etc.) is large, and is based on the temperature and humidity in the vicinity of the humidifier. Even if the humidification conditions were controlled, the relative humidity exceeded 100% near the window, and it was difficult to prevent dew condensation.
On the other hand, in the space where the bias of temperature and humidity is suppressed by the present invention, between both the temperature and humidity in the vicinity of the humidifier and the temperature and humidity in the place where dew condensation occurs (near the window, etc.). Because the difference is small, the relative humidity at the place where condensation occurs can be predicted more accurately, and the humidification conditions can be adjusted so that condensation does not occur.
Therefore, the present invention also includes a method for suppressing dew condensation in space (hereinafter, also referred to as "method for suppressing dew condensation of the present invention").
　本発明において「結露」とは、相対湿度が１００％を超えることで生じる、空気中の水蒸気の凝縮である。結露は、通常、低温下で飽和水蒸気圧の小さい窓近傍で生じる。
　本発明において「相対湿度」とは、特定の温度条件下における、空気中の水蒸気量の飽和蒸気量に対する割合（単位：％）を意味する。 In the present invention, "condensation" is the condensation of water vapor in the air, which occurs when the relative humidity exceeds 100%. Condensation usually occurs near windows with low saturated water vapor pressure at low temperatures.
In the present invention, "relative humidity" means the ratio (unit:%) of the amount of water vapor in the air to the amount of saturated steam under a specific temperature condition.
　本発明の結露抑制方法は、過熱水蒸気を供給する位置の近傍の湿度及び温度を検出する検出工程と、検出工程で検出された値に基づき、過熱水蒸気の供給条件を調節する調節工程と、を少なくとも含む。
　上記検出工程は、加湿装置近傍の湿度及び温度を監視する工程である。
　上記調節工程は、検出工程における結果に基づき、空間内の相対湿度が１００％を超えないように加湿条件を調整する工程である。 The dew condensation suppressing method of the present invention comprises a detection step of detecting humidity and temperature in the vicinity of a position where superheated steam is supplied, and an adjusting step of adjusting the supply conditions of superheated steam based on the values detected in the detection step. At least include.
The detection step is a step of monitoring the humidity and temperature in the vicinity of the humidifier.
The adjustment step is a step of adjusting the humidification condition so that the relative humidity in the space does not exceed 100% based on the result in the detection step.
　例えば、検出工程において湿度及び／又は温度の値が高い場合、空間内への過熱水蒸気の供給量を減少させ、相対湿度が低くなるように調整する。
　ここで、本発明は、従来技術に比べて温度及び湿度双方の偏りが小さいため、安全度を小さく見積もっても結露を抑制することができる。具体的には、検出工程において、過熱水蒸気を供給する位置の近傍の相対湿度が１００％に近い（例えば、相対湿度が６０％以上、６５％以上、７０％以上、又は７５％以上である）と判定された場合、過熱水蒸気の供給量を減少させるような制御であっても、結露を抑制することができる。 For example, when the humidity and / or temperature value is high in the detection step, the supply amount of superheated steam into the space is reduced and the relative humidity is adjusted to be low.
Here, in the present invention, since the bias of both temperature and humidity is smaller than that of the prior art, dew condensation can be suppressed even if the safety level is underestimated. Specifically, in the detection step, the relative humidity near the position where the superheated steam is supplied is close to 100% (for example, the relative humidity is 60% or more, 65% or more, 70% or more, or 75% or more). If it is determined that, even if the control is such that the supply amount of superheated steam is reduced, dew condensation can be suppressed.
　本発明の加湿装置を結露の抑制を目的として用いる場合、本発明の加湿装置は、加湿装置近傍の湿度及び温度を検出する検出手段、並びに、検出手段による検出値に基づいて、過熱水蒸気の供給条件を調節する調節手段を備えることが好ましい。 When the humidifier of the present invention is used for the purpose of suppressing dew condensation, the humidifier of the present invention supplies superheated steam based on the detection means for detecting the humidity and temperature in the vicinity of the humidifier and the detection value by the detection means. It is preferable to provide adjusting means for adjusting the conditions.
　加湿装置近傍の湿度及び温度を検出する検出手段としては、従来知られる湿度計、温度計等が挙げられる。 Examples of the detection means for detecting the humidity and temperature in the vicinity of the humidifier include conventionally known hygrometers and thermometers.

The present invention also provides a method for suppressing dew condensation in a space humidified by the humidifying device using the humidifying device described in the above [Use for suppressing dew condensation].
Details such as the configuration of the humidifying device are as described above.
　以下、実施例を示し、本発明を具体的に説明するが、本発明はこれらの実施例に限定されるものではない。 Hereinafter, the present invention will be specifically described with reference to Examples, but the present invention is not limited to these Examples.
　以下、加湿装置から供給される過熱水蒸気の温度、及び、過熱水蒸気を供給する風量条件が、室内空間の湿度及び温度の偏りに及ぼす影響を検討した。 Below, the effects of the temperature of the superheated steam supplied from the humidifier and the air volume conditions for supplying the superheated steam on the humidity and temperature bias in the indoor space were examined.
＜加湿装置の準備＞
　加湿装置として、従来知られる装置（国際公開第２０１３／１８０２２７号の図１等に開示されるような、加熱室、水蒸気発生装置、過熱水蒸気発生装置を備えるもの。ただし、送風ファン、ダクト、及び電気抵抗ヒータを備えない。なお、過熱水蒸気流路（過熱水蒸気供給手段）を垂直上方向に開口させた。）を用いた。
　この加湿装置は、過熱水蒸気を発生する過熱水蒸気発生手段を備え、装置内に供給された水を任意の温度に過熱し、ダクト（過熱水蒸気供給手段に相当する。）を介して空間に過熱水蒸気を供給することができる。 <Preparation of humidifier>
As a humidifying device, a device provided with a heating chamber, a steam generator, a superheated steam generator as disclosed in FIG. 1 of International Publication No. 2013/180227, etc., however, a blower fan, a duct, and a humidifying device. It is not equipped with an electric resistance heater. A superheated steam flow path (superheated steam supply means) is opened vertically upward).
This humidifying device includes a superheated steam generating means for generating superheated steam, superheats the water supplied into the device to an arbitrary temperature, and superheats steam in the space through a duct (corresponding to the superheated steam supply means). Can be supplied.
＜エアサーキュレーターの準備＞
　エアサーキュレーターとして、商品名「ＧｒｅｅｎＦａｎＣ２」（送風口の半径＝１１ｃｍ、バルミューダ社製）を用いた。
　このエアサーキュレーターは、加湿装置とは別個の装置であり、送風手段及び風量調節手段を備え、加湿装置から空間へ供給される過熱水蒸気の周囲の風量条件を任意の風量に調整することができる。 <Preparation of air circulator>
As the air circulator, the trade name "GreenFanC2" (radius of the air outlet = 11 cm, manufactured by Balmuda) was used.
This air circulator is a device separate from the humidifying device, includes a blowing means and an air volume adjusting means, and can adjust the air volume condition around the superheated steam supplied from the humidifying device to the space to an arbitrary air volume.
＜加湿装置及びエアサーキュレーターの設置＞
　閉鎖室内空間（室内長：１０ｍ、室内幅：５ｍ、室内高：２．２５ｍ）を、湿度５０％、２４℃に維持し、図１の断面図に示す配置で加湿装置１及びエアサーキュレーター２を設置した。
　具体的には、加湿装置１を台に載せ、加湿装置１のダクトの開口部を天井に向け、床から７０ｃｍ程度の高さに位置するように配置した。
　また、エアサーキュレーター２を加湿装置１と併置し、エアサーキュレーター２の送風口を天井に向け、加湿装置１のダクトの開口部と、エアサーキュレーター２の送風口とが隣り合うように調整した。 <Installation of humidifier and air circulator>
The closed indoor space (indoor length: 10 m, indoor width: 5 m, indoor height: 2.25 m) is maintained at a humidity of 50% and 24 ° C., and the humidifier 1 and the air circulator 2 are arranged in the arrangement shown in the cross-sectional view of FIG. installed.
Specifically, the humidifying device 1 was placed on a table, and the opening of the duct of the humidifying device 1 was directed toward the ceiling and arranged so as to be located at a height of about 70 cm from the floor.
Further, the air circulator 2 was juxtaposed with the humidifier 1, the air outlet of the air circulator 2 was directed toward the ceiling, and the opening of the duct of the humidifier 1 and the air outlet of the air circulator 2 were adjusted so as to be adjacent to each other.
＜室内の加湿試験＞
　加湿装置１から、９６、１３０、１７０、又は２２５℃の過熱水蒸気を６０分間空気中へ供給した。その際、エアサーキュレーター２により、過熱水蒸気の周囲の風量を、０、１．１４、２．２８、又は４．５６ｍ３／分のいずれかに調整した。 <Indoor humidification test>
From the humidifier 1, 96, 130, 170, or 225 ° C. superheated steam was supplied into the air for 60 minutes. At that time, the air volume around the superheated steam was adjusted to 0, 1.14, 2.28, or 4.56 m 3 / min by the air circulator 2.
　過熱水蒸気の供給開始から１０分後、及び６０分後の各時点で、室内の温度、及び室内の湿度を測定した。
　測定は、室内の３か所の測定地点（図１中の「×」印を参照。）において行った。測定地点は、加湿装置１から、それぞれ水平に２、４、又は６ｍ離れた地点である。 At each time point 10 minutes and 60 minutes after the start of supply of superheated steam, the temperature in the room and the humidity in the room were measured.
The measurement was performed at three measurement points in the room (see the “x” mark in FIG. 1). The measurement points are points horizontally 2, 4, or 6 m away from the humidifying device 1.
＜試験結果＞
　過熱水蒸気の温度条件、及び風量条件が同一である各時点の測定値について、偏差（測定値の平均値と、個々の測定値との差）を算出した。具体的には、各測定値について、以下４つの偏差を算出した。
（偏差－１）過熱水蒸気の供給開始から１０分後の、室内の３か所の測定地点における室内の温度の偏差
（偏差－２）過熱水蒸気の供給開始から６０分後の、室内の３か所の測定地点における室内の温度の偏差
（偏差－３）過熱水蒸気の供給開始から１０分後の、室内の３か所の測定地点における室内の湿度の偏差
（偏差－４）過熱水蒸気の供給開始から６０分後の、室内の３か所の測定地点における室内の湿度の偏差 <Test results>
The deviation (difference between the average value of the measured values and the individual measured values) was calculated for the measured values at each time point where the temperature condition and the air volume condition of the superheated steam were the same. Specifically, the following four deviations were calculated for each measured value.
(Deviation-1) Deviation of indoor temperature at 3 measurement points in the room 10 minutes after the start of supply of superheated steam (deviation-2) 3 in the room 60 minutes after the start of supply of superheated water vapor Deviation of indoor temperature at three measurement points in the room (deviation-3) 10 minutes after the start of supply of superheated steam, deviation of indoor humidity at three measurement points in the room (deviation-4) Start of supply of superheated steam Deviation of indoor humidity at three measurement points in the room 60 minutes after
　上記偏差に基づき、以下のように偏差の差を算出した。
（偏差の差（温度））「偏差－１」から「偏差－２」を引いた値
（偏差の差（湿度））「偏差－３」から「偏差－４」を引いた値 Based on the above deviation, the difference in deviation was calculated as follows.
(Difference in deviation (temperature)) Value obtained by subtracting "deviation-2" from "deviation-1" (difference in deviation (humidity)) Value obtained by subtracting "deviation-4" from "deviation-3"
　各加湿条件（過熱水蒸気の温度条件、及び風量条件）に応じた偏差の差に関する結果を図２～５に示す。
　本例において、温度及び湿度について、偏差の差が大きいことは、室内の温度及び湿度の経時的な偏りが低いことを意味する。
　なぜならば、偏差の差が大きいこと、すなわち、過熱水蒸気の供給開始から１０分後の偏差（「偏差－１」及び「偏差－３」）の数値よりも、過熱水蒸気の供給開始から６０分後の偏差（「偏差－２」及び「偏差－４」）の数値が小さいほど、室内の温度及び湿度が均一に近いことを意味するからである。 The results regarding the difference in deviation according to each humidification condition (temperature condition of superheated steam and air volume condition) are shown in FIGS. 2 to 5.
In this example, a large difference in deviation between temperature and humidity means that the temperature and humidity in the room are less biased over time.
This is because the difference in deviation is large, that is, 60 minutes after the start of supply of superheated steam, rather than the numerical value of the deviation (“deviation -1” and “deviation -3”) 10 minutes after the start of supply of superheated steam. This is because the smaller the numerical value of the deviation (“deviation-2” and “deviation-4”) is, the closer the temperature and humidity in the room are to uniform.
　本例では、温度及び湿度について、偏差の差がそれぞれ２５以上であれば室内の温度及び湿度が均一に近いと判断した。 In this example, if the difference in deviation between temperature and humidity is 25 or more, it is judged that the temperature and humidity in the room are close to uniform.
　図２～４に示されるとおり、本発明に規定される要件（すなわち、１６０℃以上の過熱水蒸気を風量２．５ｍ３／分以下の条件下で空間へ供給すること）を満たすように加湿した場合、稼働開始６０分以内という短時間にもかかわらず、室内の温度及び湿度のいずれもが均一に近くなった。
　このような効果は、風量２．５ｍ３／分以下であっても過熱水蒸気の温度が本発明に規定される要件を満たさない場合、認められなかった。 As shown in FIGS. 2 to 4, humidification was performed so as to satisfy the requirements specified in the present invention (that is, supplying superheated steam of 160 ° C. or higher to the space under the condition of an air volume of 2.5 m 3 / min or less). In this case, both the temperature and humidity in the room became almost uniform, despite the short time of 60 minutes or less from the start of operation.
Such an effect was not observed even when the air volume was 2.5 m 3 / min or less when the temperature of the superheated steam did not meet the requirements specified in the present invention.
　図５に示されるとおり、風量が２．５ｍ３／分超（本例では４．５６ｍ３／分）である場合、過熱水蒸気の温度にかかわらず、室内の温度及び／又は湿度に大きな偏りが生じた。 As shown in FIG. 5, when the air volume is more than 2.5 m 3 / min (4.56 m 3 / min in this example), there is a large bias in the indoor temperature and / or humidity regardless of the temperature of the superheated steam. occured.
