Description

本発明は、低温空気における蒸気噴霧加湿機構に関わり、特に、空調機の低温空気における蒸気噴霧加湿機構に関する。   The present invention relates to a steam spray humidification mechanism in low-temperature air, and more particularly to a steam spray humidification mechanism in low-temperature air of an air conditioner.

従来より、空気調和機には(例えば、特許文献１)、蒸気噴霧加湿機構が組み込まれているが、これら空気調和をするような低温空気中では、空気中に噴霧された蒸気が加熱空気中に比べ加湿し難い特徴がある。すなわち、蒸発する前に噴霧された蒸気が流れる位置に障害物があればここに噴霧蒸気が再凝縮し、漏水や発錆等の問題が発生する。
このため、蒸気噴霧後は、十分な蒸気の拡散空間(距離)か拡散手段(例えば、特許文献２)を設ける必要がある。また、この蒸気が拡散する距離を少しでも短くするために、蒸気を均一に噴霧する必要がある。
空気調和機においては、冷却器、加熱器においては、これら風洞の有効面に多数の噴霧孔を設けた管を林立させ、その管の噴霧孔より供給蒸気を噴霧させることで風洞内の噴霧蒸気分布を一様にしている。
特許２８４２６５２号公報 特開平１１−３０４２０３号公報 Conventionally, an air conditioner (for example, Patent Document 1) incorporates a steam spray humidification mechanism. However, in low-temperature air that performs air conditioning, steam sprayed in the air is heated in the air. There is a feature that it is hard to humidify compared to. That is, if there is an obstacle at the position where the vapor sprayed before evaporating flows, the spray vapor is recondensed here, causing problems such as water leakage and rusting.
For this reason, after vapor spraying, it is necessary to provide a sufficient vapor diffusion space (distance) or diffusion means (for example, Patent Document 2). Moreover, in order to shorten the distance which this vapor | steam diffuses as much as possible, it is necessary to spray a vapor | steam uniformly.
In the air conditioner, in the cooler and the heater, a pipe provided with a number of spray holes on the effective surface of these wind tunnels is erected, and the supply steam is sprayed from the spray holes of the pipes to spray the steam in the wind tunnel. The distribution is uniform.
Japanese Patent No. 2842652 Japanese Patent Laid-Open No. 11-304203

ところで、従来の噴霧加湿機構は、前述したように、噴霧蒸気が再凝縮することを漏水や発錆等の観点から極力避けなければならないから、噴霧された蒸気の拡散空間(距離)を設けたり、更には、風洞内の噴霧蒸気の分布を一様とし、風洞内気流による噴霧蒸気の拡散および蒸発を助長しなければならない。この為、広い範囲で一様に噴霧する装置を設けるが、蒸気噴霧式加湿装置自体の構造が大掛かりとなり、噴霧蒸気が拡散蒸発するために加湿装置以降の空間を大きくする必要がある。これらのことから、必然的に加湿装置を組込む機器が大型となるといった問題点があった。
本発明は、このような従来の噴霧加湿機構の問題点に鑑みてなされたもので、低温空気における噴霧加湿機構において、噴霧蒸気が再凝縮することを避けるために蒸気を均一に噴霧する必要が無く、また、従来必要であった噴霧蒸気の拡散蒸発空間(距離)を不要とすることで、加湿装置の構造が単純化して装置を大幅に小型化する噴霧加湿機構を提供しようとするものである。 By the way, as described above, the conventional spray humidification mechanism must avoid spray vapor recondensation as much as possible from the viewpoint of water leakage, rusting, etc. Furthermore, the spray vapor distribution in the wind tunnel must be made uniform, and the diffusion and evaporation of the spray vapor by the air flow in the wind tunnel should be promoted. For this reason, a device for spraying uniformly over a wide range is provided, but the structure of the steam spray type humidifier itself becomes large, and since the sprayed vapor diffuses and evaporates, it is necessary to enlarge the space after the humidifier. From these things, there was a problem that the apparatus which inevitably incorporates a humidifier becomes large.
The present invention has been made in view of such problems of the conventional spray humidification mechanism. In the spray humidification mechanism in low-temperature air, it is necessary to spray the steam uniformly in order to avoid recondensation of the spray steam. In addition, it is intended to provide a spray humidifying mechanism that simplifies the structure of the humidifier and greatly reduces the size of the spray by eliminating the need for the diffusion evaporation space (distance) of the spray vapor that was previously required. is there.

上記課題を解決するために、請求項１の発明は、低温空気における蒸気噴霧加湿機構において、送風機は風洞の気流に対し送風機吸込口の面を直交するように配置し、該送風機吸込口の風上側に蒸気を噴霧する加湿器を配置し、該加湿器は蒸気噴出孔と噴霧口を設けて蒸気噴出孔から蒸気を噴出させて噴霧口から風洞の気流に噴霧し、該噴霧口の幅を前記送風機吸込口の垂直投影面での噴霧口投影線上の吸込口の幅にほぼ一致させるとともに、該噴霧口を前記送風機吸込口の垂直投影面で中心近傍に配置させることを特徴とする空気調和機の低温空気における蒸気噴霧加湿機構である。 In order to solve the above-mentioned problems, the invention of claim 1 is directed to a steam spray humidification mechanism in low-temperature air, wherein the blower is disposed so that the surface of the blower suction port is orthogonal to the airflow in the wind tunnel, and the wind of the blower suction port is A humidifier for spraying steam is disposed on the upper side, and the humidifier is provided with a steam ejection hole and a spray port to eject steam from the steam ejection hole and spray the air stream in the wind tunnel from the spray port. The air conditioner is characterized in that it substantially matches the width of the suction port on the spray port projection line on the vertical projection plane of the blower suction port, and the spray port is arranged near the center on the vertical projection surface of the blower suction port. It is a steam spray humidification mechanism in the low temperature air of the machine .

本発明によれば、低温空気における蒸気噴霧加湿機構において、噴霧口を送風機吸込口の垂直投影面で中心近傍に配置させることにより、送風機内で噴霧蒸気を強制的に拡散するので、送風機に吸い込まれる前に蒸気を均一に噴霧する必要が無く、加湿器と送風機の距離が短くても、噴霧蒸気が直ぐに送風機に吸い込まれるので風洞内での噴霧蒸気の再凝縮を防止でき、したがって、従来必要であった噴霧蒸気の拡散蒸発空間(距離)を不要とし、加湿装置の構造が単純化して装置を大幅に小型化することができる。   According to the present invention, in the steam spray humidification mechanism in low-temperature air, the spray port is forcibly diffused in the blower by disposing the spray port in the vicinity of the center on the vertical projection surface of the blower suction port. Even if the distance between the humidifier and the blower is short, the sprayed steam is immediately sucked into the blower so that recondensation of the sprayed steam in the wind tunnel can be prevented. The diffusion vaporization space (distance) of the spray vapor which is the above is unnecessary, the structure of the humidifier is simplified, and the apparatus can be greatly downsized.

[実施例１]
本発明の低温空気における蒸気噴霧加湿機構を空気調和機に適用した実施例を図面に沿って説明するが、図１及び図３は、実施例１の全体の概略を示すものである。
図１乃至図３において、符号１は、本実施例の蒸気噴霧加湿機構を組み込んだ空気調和機１で、空気調和機１の枠体１１内には、図１から明らかなように水平方向の右側の風上側から順に、熱交換器(コイル)２、蒸気噴霧型の加湿器３、送風機４が直列に配置されており、空気調和機１のコイル等を設けた枠体１１と送風機４の設けた枠体１３とは振動を防止するためキャンバス布等の防振連結部材１４で機密に連結されている。
空気調和機１には室内の一部や外気Ａ1が取り込まれ、熱交換器２を通過することによって暖め、或いは、冷やされた空気Ａ2が送風機４に流れるが、送風機４の直前に加湿器３が配置されている。 [Example 1]
An embodiment in which the steam spray humidification mechanism in low-temperature air according to the present invention is applied to an air conditioner will be described with reference to the drawings. FIGS. 1 and 3 show an overall outline of the first embodiment.
In FIG. 1 thru | or FIG. 3, the code | symbol 1 is the air conditioner 1 incorporating the steam spray humidification mechanism of a present Example, and as FIG. The heat exchanger (coil) 2, the steam spray type humidifier 3, and the blower 4 are arranged in order from the right windward side, and the frame 11 and the blower 4 provided with the coil of the air conditioner 1 and the like are arranged in series. In order to prevent vibration, the provided frame 13 is secretly connected by a vibration-proof connecting member 14 such as a canvas cloth.
A part of the room and outside air A1 are taken into the air conditioner 1 and warmed or cooled air A2 flows through the heat exchanger 2 through the heat exchanger 2, but the humidifier 3 immediately before the fan 4 flows. Is arranged.

この加湿器３は、主に図４に示すように、蒸気供給管３１(図３を参照)が加湿器枠体(ボックス)３２内の複数の蒸気噴出ノズル３３を有する加湿管本体３４に接続され、この蒸気噴出ノズル３３の噴出方向は下向に設けられており、この蒸気噴出ノズル３３を下向にしたのは、再凝縮水の飛散を防止するためである。また、加湿器枠体３２の上面部には噴霧口３５が設けられ、この噴霧口３５には、必要に応じて水滴除去のためのエリミネータ３６が設けられている。
この噴霧口３５は、蒸気噴出ノズル３３から蒸気を噴出させて、更に、噴霧口３５から風洞の水平方向の気流Ａ2に噴霧し、この噴霧口３５が、後述するように、送風機４の吸込口412(インレットコーン４１)の垂直投影面で中心近傍に配置されている。
なお、加湿器枠体(ボックス)３２の底部321には、水滴が落下して水が溜まるが、左端に設けた排水口３７及び排水管371から外部に排出される。 In the humidifier 3, as shown mainly in FIG. 4, a steam supply pipe 31 (see FIG. 3) is connected to a humidifying pipe body 34 having a plurality of steam ejection nozzles 33 in a humidifier frame (box) 32. The jet direction of the steam jet nozzle 33 is set downward, and the reason why the steam jet nozzle 33 is set downward is to prevent recondensed water from scattering. Further, a spray port 35 is provided on the upper surface of the humidifier frame 32, and an eliminator 36 for removing water droplets is provided in the spray port 35 as necessary.
This spray port 35 causes the steam to be ejected from the steam ejection nozzle 33 and further sprays from the spray port 35 to the horizontal airflow A2 of the wind tunnel, and this spray port 35 is the suction port of the blower 4 as will be described later. 412 (inlet cone 41) is arranged near the center on the vertical projection plane.
Although water drops fall and accumulate in the bottom 321 of the humidifier frame (box) 32, the water is collected from the drain port 37 and the drain pipe 371 provided at the left end.

送風機４は、プラグファン或いはシロッコファン等の片吸込型の送風機４で、ファンランナ(回転羽根)４２の前面にインレットコーン４１を配置し、インレットコーン４１の外枠411が枠体１１内で区画を形成する垂直のブランクオフプレート１２に取り付けられている。この送風機４も、風洞の気流Ａ2に対しベルマウス型のインレットコーン４１の吸込口412を垂直に配置し、ファンランナ(回転羽根)４２で空気を側面から排出し、ダクト(図示せず)等から空調された空気Ａ3となって室内に供給される。また、風下側には送風機４を駆動する駆動モータ４３が連結されている。
この送風機１のファンランナ４２の回転により、加湿器３の噴霧口３５から噴霧された噴霧蒸気Ｂを強制的に拡散させるとともに、送風機４のファンライナー４２の発熱により噴霧蒸気Ｂの蒸発を促している。 The blower 4 is a single-suction blower 4 such as a plug fan or a sirocco fan. An inlet cone 41 is disposed on the front surface of a fan runner (rotary blade) 42, and an outer frame 411 of the inlet cone 41 is partitioned in the frame 11. Are attached to a vertical blank-off plate 12 that forms This blower 4 also has a suction port 412 of a bell mouth type inlet cone 41 arranged perpendicularly to the airflow A2 in the wind tunnel, exhausts air from the side by a fan runner (rotary blade) 42, a duct (not shown), etc. The air-conditioned air A3 is supplied to the room. A drive motor 43 that drives the blower 4 is connected to the leeward side.
The rotation of the fan runner 42 of the blower 1 forcibly diffuses the spray vapor B sprayed from the spray port 35 of the humidifier 3 and promotes evaporation of the spray vapor B by the heat generated by the fan liner 42 of the blower 4. Yes.

ここで、インレットコーン４１の吸入口412の円の内径Ｄ、加湿器３の中心から送風機吸込口412までの距離Ｌ、送風機４の吸込口412の中心から加湿器の噴霧口35までの距離Ｈ、加湿器３の横方向の有効間隔Ｐとの関係を、図を参照して示す。
各図中、符号Ｄ、Ｌ、Ｈ、Ｐは下記の長さである。
Ｄ：インレットコーン４１の内径(吸込口)
Ｌ：加湿器のセンターからインレットコーンの吸込口412までの距離
Ｈ：インレットコーン(吸込口)の中心線から、加湿器の噴霧口までの距離
Ｐ：加湿器の横方向の有効間隔 Here, the inner diameter D of the circle of the inlet 412 of the inlet cone 41, the distance L from the center of the humidifier 3 to the blower inlet 412, the distance H from the center of the inlet 412 of the blower 4 to the spray port 35 of the humidifier The relationship between the effective distance P in the lateral direction of the humidifier 3 will be described with reference to the drawings.
In each figure, symbols D, L, H, and P have the following lengths.
D: Inner cone 41 inner diameter (suction port)
L: Distance from the center of the humidifier to the inlet 412 of the inlet cone H: Distance from the center line of the inlet cone (suction inlet) to the spray port of the humidifier P: Effective distance in the horizontal direction of the humidifier

まず、インレットコーンの中心から、加湿器３の噴霧口３５までの距離が、どの程度が良いかを調べ、この結果を[表１]に示す。
ここで、この実験は、実施例１と同じ配置の空気調和機で、室温状態(２０℃)で送風機４の吸込口412の中心線上(Ｈ＝０)で噴霧口３４から蒸気を噴霧させ、拡散器等を存在させない状況下で、インレットコーン(吸込口412)の中心から、その内径Ｄとの対比で、加湿器３の噴霧口３５の中心までの距離Ｌを変化させ、枠体１１の風洞内、ブランクオフプレート１２、インレットコーン４１に再凝縮水が生じるか否かを調べた。なお、この場合の加湿器３の横方向の有効間隔Ｐは、内径Ｄと同じにした。 First, the distance from the center of the inlet cone to the spray port 35 of the humidifier 3 was examined and the result is shown in [Table 1].
Here, this experiment is an air conditioner having the same arrangement as in Example 1, and vapor is sprayed from the spray port 34 on the center line (H = 0) of the suction port 412 of the blower 4 at room temperature (20 ° C.). In a situation where a diffuser or the like is not present, the distance L from the center of the inlet cone (suction port 412) to the center of the spray port 35 of the humidifier 3 is changed in comparison with the inner diameter D thereof. It was investigated whether recondensed water was generated in the wind tunnel, the blank off plate 12, and the inlet cone 41. In this case, the effective distance P in the horizontal direction of the humidifier 3 is the same as the inner diameter D.

Figure 0004716361
[Table 1] [Correlation between distance / L dimension from inlet cone and D dimension]
Figure 0004716361

上記[表１]からは、Ｌが１／２＊Ｄ以上であれば、インレットコーンに再凝縮水が生じないことが判る。ただし、後述するように、本発明の特徴は、従来のように加湿器３を送風機４から離(３Ｄ以上)して配置するのではなく、送風機４の近傍に配置して、全体としてコンパクトにすることであり、言い換えれば、加湿器３までの距離Ｌを２Ｄ以内にも配置できることであり、好ましくは、Ｄ／２＜Ｌ＜２Ｄの範囲が良い。
なお、本実施例１では、インレットコーンの中心吸込口412から加湿器３の噴霧口３５までの距離Ｌは、インレットコーン４１の中心吸込口412の内径Ｄとほぼ同じにした。 From the above [Table 1], it can be seen that if L is 1/2 * D or more, no recondensed water is generated in the inlet cone. However, as will be described later, the feature of the present invention is that the humidifier 3 is not disposed away from the blower 4 (3D or more) as in the prior art, but is disposed in the vicinity of the blower 4 so as to be compact as a whole. In other words, the distance L to the humidifier 3 can be arranged within 2D, and preferably a range of D / 2 <L <2D is preferable.
In the first embodiment, the distance L from the inlet port 412 of the inlet cone to the spray port 35 of the humidifier 3 is substantially the same as the inner diameter D of the inlet port 412 of the inlet cone 41.

次に、加湿器３のインレットコーン４１に対する取り付け高さと、加湿器３の蒸気を噴出する噴霧器３５の幅について調べ、この結果を[表２]に示す。   Next, the height of the humidifier 3 attached to the inlet cone 41 and the width of the sprayer 35 for jetting the steam of the humidifier 3 were examined, and the results are shown in [Table 2].

[表２][加湿器３の取り付け位置について]

Figure 0004716361
[Table 2] [Mounting position of humidifier 3]
Figure 0004716361

上記[表２]からは、噴霧口３５の端部が、インレットコーン４１の内径の内側にあれば、ブランクオフプレート１２やインレットコーン４１に再凝縮水が生じないことが判る。これは、インレットコーン４１中心から加湿器３の噴霧口３５までの距離Ｈが離れすぎたり、また幅Ｐが広くなりすぎると、図５(ａ)の範囲Ｘ１に示すように、加湿蒸気Ｂがブランクオフプレート１２及びインレットコーン４１に接触しながら吸い込まれるため、その部分で再凝縮水が発生するためと考えられる。 逆に、インレットコーン４１中心と噴霧口３５までの距離Ｈが短く、噴霧口３５が吸入口412の中心線Ｙ上の近傍であると、図５(ｂ)の範囲Ｘ２に示すように、加湿蒸気Ｂがブランクオフプレート１２及びインレットコーン４１に余り接触しないので、再凝縮水が発生することが少ないためと考えられる。
なお、本実施例１では、インレットコーン４１の吸込口412の中心線から、加湿器３の噴霧口３５までの距離Ｈを０として、ほぼ吸込口412の中心軸Ｙ上に噴霧口３５を配置させた。 From the above [Table 2], it can be seen that if the end of the spray port 35 is inside the inner diameter of the inlet cone 41, no recondensed water is generated in the blank off plate 12 or the inlet cone 41. This is because if the distance H from the center of the inlet cone 41 to the spray port 35 of the humidifier 3 is too far or the width P becomes too wide, the humidified steam B is generated as shown in a range X1 in FIG. It is considered that recondensed water is generated in that portion because it is sucked in contact with the blank off plate 12 and the inlet cone 41. Conversely, if the distance H between the center of the inlet cone 41 and the spray port 35 is short and the spray port 35 is in the vicinity of the center line Y of the suction port 412, as shown in the range X2 of FIG. It is considered that since the steam B does not contact the blank off plate 12 and the inlet cone 41 so much, recondensed water is rarely generated.
In the first embodiment, the spray port 35 is disposed substantially on the central axis Y of the suction port 412 with the distance H from the center line of the suction port 412 of the inlet cone 41 to the spray port 35 of the humidifier 3 being zero. I let you.

また、噴霧口３５の幅Ｐを、送風機吸込口の垂直投影面の範囲Ｘ３での噴霧口投影線上の吸込口の幅(吸収口投影の円の切断線の弦の長さ)と一致させれば噴霧量は最大となるが、本実施例１では、加湿器３の蒸気噴出する噴霧口３５の幅Ｐを、インレットコーン４１の中心の吸込口412の内径Ｄと一致させた。これは噴霧効量が、幅Ｐに比例して向上するので、再凝縮水が発生しない範囲での最大値である吸込口412の内径Ｄ(Ｈ＝０において)とした。また、これ以上幅Ｐを大きくすると噴霧効率は向上するが、再凝縮水が発生して不都合が生じるので、噴霧口３５の幅Ｐは吸込口412の内径Ｄにほぼ一致させるのが好適値である。   Moreover, the width P of the spray port 35 can be made to coincide with the width of the suction port on the spray port projection line in the range X3 of the vertical projection plane of the blower suction port (the length of the string of the cutting line of the circle of the absorption port projection). In this embodiment, the width P of the spray port 35 through which the steam is jetted from the humidifier 3 is made equal to the inner diameter D of the suction port 412 at the center of the inlet cone 41. This is because the spraying efficiency is improved in proportion to the width P, so that the inner diameter D (in the case of H = 0) of the suction port 412 which is the maximum value in the range where no recondensed water is generated. Further, if the width P is further increased, the spray efficiency is improved, but recondensed water is generated, resulting in inconvenience. Therefore, it is preferable that the width P of the spray port 35 substantially matches the inner diameter D of the suction port 412. is there.

以上の結果から、加湿器３の噴霧口３５の配置は、図６(ａ)及び図６(ｂ)の斜線部分３に示すように、インレットコーン４１の中心線Ｙの延長上で、その吸込口と同じ形状(直径)の筒状の(垂直投影面の)範囲Ｘ３であり、かつ、インレットコーン(吸込口４１)の垂直面から、その内径Ｄの１／２以上の距離を離した範囲であれば、蒸気の再凝縮が発生することが少ないことを見いだした。
このことは、噴霧口３５の幅Ｐを送風機吸込口(円形)の垂直投影面の範囲Ｘ３での噴霧口投影線上の吸込口の幅(吸収口投影の円の切断線の弦の長さ)以下にすれば良く、逆に、範囲Ｘ３からはずれた位置に噴霧口３５を配置することは再凝縮水が発生しやすくなる。したがって、インレットコーン４１の吸込口412の中心から、加湿器３の噴霧口３５までの距離Ｈを０として、ほぼ吸込口412の中心軸Ｙ上に噴霧口３５を配置させれば、噴霧口３５の幅Ｐは送風機吸込口の直径Ｄ以下にすれば良い。
以上のことから、上記の範囲Ｘ３内であれば加湿器３の噴霧口３５を、送風機４に近づけてもよく、実施例１の蒸気噴霧式加湿器でも、送風機４内で噴霧蒸気が強制的に拡散されるので、送風機に吸い込まれる前に蒸気を均一に噴霧する必要が無く、直ちに送風機に吸い込まれるので風洞内での噴霧蒸気の再凝縮を防止でき、また、従来必要であった噴霧蒸気の蒸発空間（距離）が不要になり、このため加湿装置の構造を単純化でき、更には、装置の大幅な小型化が実現できる。 From the above results, the spray port 35 of the humidifier 3 is disposed on the extension of the center line Y of the inlet cone 41 as shown by the hatched portion 3 in FIGS. 6 (a) and 6 (b). It is a cylindrical range (in the vertical projection plane) having the same shape (diameter) as the mouth (in the vertical projection plane), and a range separated from the vertical plane of the inlet cone (suction port 41) by a distance of 1/2 or more of its inner diameter D Then, it was found that recondensation of steam is less likely to occur.
This means that the width P of the spray port 35 is the width of the suction port on the spray port projection line in the range X3 of the vertical projection plane of the blower suction port (circular) (the length of the chord of the cutting line of the circle of the absorption port projection). On the contrary, if the spray port 35 is disposed at a position deviated from the range X3, recondensed water is likely to be generated. Accordingly, when the distance H from the center of the suction port 412 of the inlet cone 41 to the spray port 35 of the humidifier 3 is set to 0, and the spray port 35 is disposed substantially on the central axis Y of the suction port 412, the spray port 35 The width P may be equal to or less than the diameter D of the blower inlet.
From the above, the spray port 35 of the humidifier 3 may be close to the blower 4 as long as it is within the above-described range X3, and even in the steam spray humidifier of the first embodiment, the spray vapor is forced in the blower 4. Therefore, it is not necessary to spray the vapor uniformly before it is sucked into the blower, and since it is immediately sucked into the blower, it is possible to prevent recondensation of the sprayed vapor in the wind tunnel. Therefore, the structure of the humidifying device can be simplified, and further, the device can be significantly reduced in size.

なお、本発明の特徴を損うものでなければ、上記の各実施例に限定されるものでないことは勿論であり、図７〜図１０の実施例２〜実施例５に示すような空気調和機に用いても良いことは勿論である。
すなわち、図７に示す実施例２は、空気流Ａ１が下から上にＡ２からＡ３に流れるタイプの空気調和機に本発明の低温空気における蒸気噴霧加湿機構を適用したものであり、図８に示す実施例３は、空気流Ａ１が屈曲して逆コの字状に流れるタイプの空気調和機に本発明の蒸気噴霧加湿機構を適用したものであり、図９に示す実施例４は、空気流Ａ１が屈曲してＬ字状に流れるタイプの空気調和機に本発明の蒸気噴霧加湿機構を適用したものであり、図１０に示す実施例５は、実施例３とほぼ同様に、空気流Ａ１が屈曲して逆コの字状に流れるタイプの空気調和機に本発明の蒸気噴霧加湿機構を適用したものである。 In addition, as long as the characteristics of the present invention are not impaired, it is needless to say that the present invention is not limited to the above-described embodiments, and air conditioning as shown in Embodiments 2 to 5 of FIGS. Of course, it may be used in the machine.
That is, Example 2 shown in FIG. 7 is an application of the steam spray humidification mechanism in low-temperature air of the present invention to an air conditioner in which the air flow A1 flows from A2 to A3 from bottom to top. Example 3 shown is an example in which the steam spray humidification mechanism of the present invention is applied to an air conditioner of the type in which the air flow A1 is bent and flows in an inverted U shape.
