Definitions
- the present invention relates to a humidifying device, a method for creating a humidified space, and a method for suppressing dew condensation in the space.
- Humidity and the like in a closed indoor space have a great influence on the safety and comfort of living and working in the space. Therefore, various techniques for controlling humidity and the like in a closed indoor space have been proposed.

- a humidifying device that humidifies by supplying is described.
- Patent Document 1 discloses that superheated steam is blown and supplied to a space, the present inventor may unexpectedly have an adverse effect that the blown air promotes the above bias. I found.
- the present invention has been made in view of the above situation, and an object of the present invention is to provide a humidifying device capable of suppressing a bias in both humidity and temperature in a space.
- the present inventors have found that the above problems can be solved by adjusting the temperature of the superheated steam supplied from the humidifying device to the space and the air volume when supplying the superheated steam, and have completed the present invention. .. More specifically, the present invention provides the following.
- a humidifier A means of generating superheated steam that generates superheated steam, The superheated steam supply means for supplying the superheated steam generated from the superheated steam generating means to the space, And A humidifying device that humidifies by supplying superheated steam of 160 ° C or higher to a space under the condition of an air volume of 2.5 m 3 / min or less.
- the humidifier is A detection means for detecting the humidity and temperature in the vicinity of the humidifier, and An adjusting means for adjusting the supply condition of superheated steam based on the detected value by the detecting means, and And further prepare The humidifying device according to (1), which suppresses dew condensation in the space.
- the humidifying device A means of blowing superheated steam and An air volume adjusting means for adjusting the air volume of the air blowing means within a range of 2.5 m 3 / min or less, and an air volume adjusting means.
- the humidifying device according to (1) or (2).
- a method of creating a humidified space comprising the step of supplying superheated steam of 160 ° C. or higher to a space under the condition of an air volume of 2.5 m 3 / min or less.
- a humidifying device capable of suppressing a bias in both humidity and temperature in a space.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- a high air volume for example, an air volume of more than 2.5 m 3 / min
- 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.

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.

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.

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.

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.

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.

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。

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").

＜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－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"

(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.

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.
