Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は気化式加湿器及びこれを用いた加湿システムに
関する。The present invention relates to a vaporization type humidifier and a humidification system using the same.
気化式加湿器は運転費が少額で済むこと、クリーン加湿
が可能で結露の危険がないこと等から種々の形式のもの
が市販されている。現在知られている気化式加湿器を列
挙すれば下記のとおりである。Various types of vaporization type humidifiers are commercially available because of low operating costs, clean humidification and no risk of condensation. The vaporization type humidifiers currently known are listed below.
滴下式：ハニカム状や格子状または波板状の吸水材の上
から散水し濡れた吸水材（加湿材）に通風させ加湿す
る。吸水材（加湿材）上部に滴下された水は枝別れし、
大表面積の加湿材を濡らして行くため滴下位置から離れ
た所ほど、また支流になるほど水量が少なくなり、すべ
てを濡らすためには大量の給水が必要となるという欠点
がある。Dropping method: Water is sprayed from above a honeycomb-shaped, lattice-shaped, or corrugated water-absorbing material, and the wet water-absorbing material (humidifying material) is ventilated to humidify it. Water dripping on the upper part of the water absorbing material (humidifying material) branches off,
Since the moisturizing material having a large surface area is wetted, there is a drawback that the amount of water decreases as the distance from the dropping position increases, and the tributary becomes a tributary, and a large amount of water needs to be supplied in order to wet everything.
透湿膜式：気体のみ透過するチューブ状の膜内に水を入
れ、膜外に通風させて加湿する。微細な小孔が空気・水
の汚れでつまり易く寿命が短く、保守も困難であるとい
う欠点がある。Moisture-permeable membrane type: Water is put into a tube-shaped membrane that allows only gas to permeate, and air is ventilated outside the membrane to humidify it. There are drawbacks that minute holes are easily clogged with air and water, their life is short, and maintenance is difficult.
流下式：上部水槽より毛細管力によりメッシュ状吸水材
を濡らし、ここに通風し加湿する。上部水槽を完全に水
平に取付けることが難しく、傾きにより吸い上げ量が低
い位置と高い位置とでは大きく異なり、従ってぬれ分布
にも大きな差が生ずるという欠点がある。Flow-down method: Wet the mesh-shaped water-absorbing material from the upper water tank by capillary force, and ventilate here to humidify. It is difficult to mount the upper water tank completely horizontally, and there is a drawback that the position where the suction amount is low and the position where the suction amount is high are greatly different due to the inclination, and thus a large difference occurs in the wetting distribution.
回転式：フィルター状加湿材を上下一対の回転体間に掛
け回し、下部の回転体付近を水槽に付け、そこで加湿材
を浸水させ濡らした後通風させ加湿する。加湿材内を通
過する空気中の垢で目詰まりし、メンテナンスを短時間
で繰り返す必要があり、また空気圧損が大きく、荷働部
の寿命も短いという欠点がある。Rotational type: A filter-like humidifying material is hung between a pair of upper and lower rotating bodies, and the lower rotating body is attached to a water tank, where the humidifying material is soaked and wet, and then ventilated for humidification. It has the drawbacks that it is clogged with dirt in the air passing through the humidifying material, maintenance must be repeated in a short time, air pressure loss is large, and the life of the loading section is short.
吸い上げ式：紙等の加湿材下部を浸水させ、水を毛細管
力で吸い上げて濡らし、そこに通風して加湿する。吸い
上げ高さに限度があり、加湿量が小さく、また加湿材中
に水不純物が析出して短期間で寿命となるという欠点が
ある。Wicking method: The lower part of a humidifying material such as paper is soaked in water, water is sucked up by capillary force to wet it, and the air is ventilated to humidify it. There are drawbacks such that the suction height is limited, the amount of humidification is small, and water impurities are deposited in the humidifying material to shorten the life.
また各方式に共通する欠点としては、給水を停止すると
湿度制御性が悪い、即ち保水量が多い加湿材が乾くまで
加湿が続いていわゆるオーバーシュートが大きくなり、
正確な湿度制御ができないという点がある。また暖房能
力に余裕がないと室温が低くなる等の欠点もあるため、
上述の各方式は現在のところ加湿器の主力とはなりえな
いものとなっている。As a disadvantage common to each method, when water supply is stopped, the humidity controllability is poor, that is, humidification continues until the humidifying material with a large amount of water retention dries and the so-called overshoot increases.
There is a point that accurate humidity control is not possible. In addition, if there is no room in heating capacity, there are drawbacks such as lowering the room temperature,
At present, the above-mentioned methods cannot be the mainstay of the humidifier.
本発明は上述した従来の問題に鑑みてなしたもので、下

としたものである。The humidifier according to the present invention, in order to achieve the above object,
A holding structure for ventilating the inside of the frame body with a frame structure consisting of an upper frame, a lower frame and a pair of side frames, a moisturizing material made of a non-woven fabric having a water retaining capacity and a water absorbing capacity in a gate shape, and a small hole for water supply. A water supply pipe that has one or more and is connected to a water supply source, the upper frame of the holding structure is a tank for supplying water from the water supply pipe, and one or more of the humidifying materials is exposed at the central flat portion in the tank. At the same time, a pair of hanging parts connected to the central flat part are arranged in the holding structure in parallel to the air flow passing through the holding structure, and the tip of the water supply pipe is blocked to position above the humidifying member. With the horizontal arrangement in the tank, the position of the small hole is made to correspond to the flat surface of the humidifying material, and the water supplied from the water supply source is passed from the small hole to the central flat portion of the humidifying material. It has a structure that enables dropping.

ができる。A humidifier according to the present invention holds a lower frame of the holding structure between the pair of side frames in a vertically variable position, and causes a lower end of a hanging portion of the humidifying material to pass through the lower frame and project outward. A rod-shaped member may be passed through the protruding portion of the humidifying member in a direction extending between the side frames, and the rod-shaped member may be pushed down by the lower surface of the lower frame to adjust the tension of the humidifying member. .
次に本発明の作用を説明する。 Next, the operation of the present invention will be described.

る。When the control valve is opened and water is supplied to the water supply pipe from the water supply source, the water pressure applied to the water supply pipe causes water to drop from all the small holes to the central flat portion of the humidifying material. Water pressure, water pipe diameter,
By appropriately selecting the small hole diameter, the water pressure in the water supply pipe can be made uniform over the entire length, and the amount of water dropped from the small holes can be made uniform.
給水時は多量の水が給水され、加湿材保水量以上の流れ
となり、加湿材の吸水力と重力により加湿材全体を万遍
なく濡らす。この時、加湿材表面等に付着していた空気
中の微細な塵垢が一緒に流下する。At the time of water supply, a large amount of water is supplied, and the flow exceeds the water retention capacity of the humidifying material, and the water absorbing power of the humidifying material and the gravity evenly wet the entire humidifying material. At this time, fine dust in the air adhering to the surface of the humidifying material flows down together.
給水時間を調整して加湿量より多少多い水量に設定すれ
ば、給水をOFFとしても加湿材内には水が十分保水され
ており、給水をOFFする時間を余り長時間としなければ
水の滴下は続くので、濡れのばらつき、乾きやスケー
ル、スライムの発生はない。If you adjust the water supply time and set the amount of water to be slightly higher than the amount of humidification, the water will be sufficiently retained in the humidifier even if the water supply is turned off. As it continues, there is no variation in wetness, dryness, scale, or slime.
門形状の加湿材を風流に対して垂下面を平行に沿わせる
ことにより整流格子状に配されるため、空気は少ない圧
損で流れる。Since the gate-shaped humidifying material is arranged in a rectifying grid by arranging the vertical surfaces parallel to the wind flow, the air flows with a small pressure loss.
以下本発明の実施例を図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.

It is a side surface sectional view which follows the -Y line. The humidifier according to the present embodiment has a casing 1 serving as a holding structure, a plurality of humidifying materials 2, ..., Water supply holes connected to a solenoid valve 4 for turning on / off water supply from a water supply source. It consists of a pipe 5.

力を調節できるようになっている。The moisturizing material 2 has a water-retaining capacity of, for example, about 0.05 to 0.5 g / cm 2 per unit surface area, and is made of a non-woven fabric having a water-absorbing ability to absorb water by 50 mm or more. Are arranged so that the vertical surface 10 is parallel to the wind flow A. Further, the flat portion 9 of the humidifying material 2 is exposed in the drip tank 6, and the lower end portion of the hanging bottom surface 10 projects downward from the lower frame 7. A round bar 11 is passed through the projecting portion of the hanging bottom surface 10 on the lower surface side of the lower frame 7. By changing the position of the lower frame 7 with a screw 12, the tension applied to the humidifying material 2 can be adjusted. There is.

の水を繰り返しタイマー13により制御される電磁弁４及
びストレーナー付きの減圧弁14を介して接続してある。The number of the small holes 3 provided in the water supply pipe 5 is the same as the number of the humidifying materials 2, and they are arranged above the flat portion 9 of the humidifying material 2. Water from a water absorption source is repeatedly connected to the water supply pipe 5 through a solenoid valve 4 controlled by a timer 13 and a pressure reducing valve 14 with a strainer.

方から均等量ずつ滴下散水される。Water from a water supply source (not shown) first enters the pressure reducing valve 14 with a strainer to remove dust such as iron rust in the pipe, and then reduces the pressure to make the water pressure constant. The water having a constant water pressure enters the water supply pipe 5 through the solenoid valve 4, and is sprayed from each small hole 3 at a uniform water pressure onto the flat portions 9 of each of the plurality of humidifying materials 2 from above in equal amounts.

の下端から排水されていく。The water dripping on the flat portion 9 of the humidifying material 2 spreads horizontally in the flat portion 9 due to the capillary force, and when the flat portion 9 has a water retention amount or more, the water is gradually absorbed by the lower hanging surface 10.
This wets the entire surface of the humidifying material 2. By ventilating between the humidifying materials 2 thus wet, the ventilated air A evaporates due to the partial pressure difference of water vapor, and the humidification target area is humidified by the moist air A ′ blown out from the humidifier. In addition, the water with impurities concentrated by evaporation of water is

In the figure, 15 is a heat exchanger, 16 is a humidifier, and 17 is a fan. The arrow in the figure indicates the direction of air flow (same in FIGS. 4 to 6), and the humidifier 16 is provided on the downstream side of the heat exchanger 15.

The humidifier 16 and the fan 21 are arranged there.
第６図は加湿器を単独使用する加湿システムを示し、ダ
クト22内に加湿器16とファン23を配置して構成してあ

これら種々の使用態様において、第１図に示すように排
水部分に導電率センサー24を設置し、導電率が大きくな
った際に給水時間、即ち電磁弁４のON時間が長くなるよ
うに繰り返しタイマー13に信号入力されるよう構成すれ
ば、スケールが析出しない最小給水量にて自動運転でき
る。In these various usage modes, as shown in FIG. 1, a conductivity sensor 24 is installed in the drainage portion, and when the conductivity becomes large, the water supply time, that is, the ON time of the solenoid valve 4 is lengthened by a repeat timer. If it is configured so that a signal is input to 13, the automatic operation can be performed with the minimum amount of water supply so that scale does not deposit.
また第２図に示すように加湿器の一次側に温度センサー
25を取付け、流入する空気Ａの温度が高くなった際に給
水時間が長くなるよう繰り返しタイマー13に信号入力さ
れるよう構成すれば、空気温度が高い時には加湿量が多
くなり、このため加湿量が多くなってもスケールが析出
しない最小給水量にて自動運転できる。As shown in Fig. 2, a temperature sensor is installed on the primary side of the humidifier.
If 25 is attached and the signal is repeatedly input to the timer 13 so that the water supply time becomes long when the temperature of the inflowing air A becomes high, the humidification amount increases when the air temperature is high. It can be operated automatically with the minimum water supply so that scale does not precipitate even if the amount of water increases.
さらに第２図に示すように加湿対象となる室内等に比例

27の加熱量を大きくすれば加湿量を増やせる。具体的に
は予熱器として電気ヒータを用い、サイリスタにより電
力調整すればよい。Further, as shown in FIG. 2, if the proportional humidity sensor 26 is provided in the room to be humidified and the preheater 27 is arranged on the primary side of the humidifier, if the humidification amount is small and the set humidity is not reached, A signal corresponding to the shortage amount output from the proportional humidity sensor 26 is input to the preheater 27, and the larger the shortage amount, the preheater
The amount of humidification can be increased by increasing the heating amount of 27. Specifically, an electric heater may be used as a preheater, and power may be adjusted by a thyristor.
また加湿器の二次側もしくは室内に（第２図では室内
側）温度センサー28を配し、一次側の予熱器27と連動さ
せれば、加湿による断熱冷却分だけ加熱でき、室温低下
をなくせる。If a temperature sensor 28 is installed on the secondary side of the humidifier or indoors (inside the room in Fig. 2) and is linked to the preheater 27 on the primary side, only the amount of adiabatic cooling due to humidification can be heated and there is no drop in room temperature. Let

数制御が可能となる。Although not shown, if the water supply system including the water supply pipes 5 and the solenoid valves 4 is arranged in a plurality of rows and the small holes 3 provided in the water supply pipes 5 are provided for each humidification material 2, the number of the humidification materials 2 for dripping water is reduced. It becomes possible to control.
次に実際的な設計例をエアコンに内蔵する場合について
説明する。Next, a case where a practical design example is built in an air conditioner will be described.
第３図に示すように熱交換器の二次側直後に加湿器を配
置した場合加湿器に通風される空気条件は一般的に温度
t1は40℃DB、相対湿度Φ１は15％RH、絶対湿度x1は0.00
69kg/kg、風速2m/sぐらいが多く、風量はエアコン馬力
数によって決まるが個別分散化空調で多いとされる５馬
力クラスで考えると30m/minぐらいとなる。また、この
場合天埋め型が多いので高さは300mmぐらいが多い。As shown in Fig. 3, when the humidifier is placed immediately after the secondary side of the heat exchanger, the air condition ventilated by the humidifier is generally temperature.
t1 is 40 ℃ DB, relative humidity Φ1 is 15% RH, absolute humidity x1 is 0.00
69kg / kg, wind speed is 2m / s, and air volume depends on the number of horsepower of the air conditioner, but it is about 30m / min in the case of 5 horsepower class, which is considered to be large in individual distributed air conditioning. Also, in this case, there are many buried type, so the height is usually around 300 mm.
以上の条件から加湿器の幅を算出すると、 30m3/min÷（60×２×0.3） ＝0.83m となる。When the width of the humidifier is calculated from the above conditions, it is 30m 3 /min÷(60×2×0.3)=0.83m.
５馬力クラスの必要加湿量は3.6kg/hとされているか
ら、前記の条件で3.6kg/h加湿した場合の変化を空気線
図上にて示すと第７図のようになる。図中の15％の飽和
線ΦのＡ点が吸い込みでここから加湿器に空気が通過す
るに従い湿球温度一定線Ｚ上に加湿される。仮にバイパ
スがなくすべての空気が水面と同一湿度になったとする
と100％の飽和線との交点Ｃまで加湿される。この場合
を飽和効率100％と称する。Since the required humidification amount for the 5 horsepower class is 3.6 kg / h, the change when humidifying at 3.6 kg / h under the above conditions is shown on the psychrometric chart as shown in FIG. 7. The point A of the saturation line Φ of 15% in the figure is sucked in, and is humidified on the constant wet-bulb temperature line Z as the air passes from here to the humidifier. If there is no bypass and all the air has the same humidity as the water surface, it will be humidified up to the intersection C with the 100% saturation line. This case is called 100% saturation efficiency.
加湿量3.6kg/h、風量30m3/minにてＡ点より加湿すると
絶対湿度の差Δｘは、 Δｘ＝3.6÷（30×60×1.2） ＝0.00167（kg/kg） となる。When humidifying from point A at a humidification rate of 3.6 kg / h and an air flow rate of 30 m 3 / min, the absolute humidity difference Δx is Δx = 3.6 ÷ (30 × 60 × 1.2) = 0.00167 (kg / kg).
従って上記加熱を行なった後の絶対湿度x2は x2＝x1＋Δｘ ＝0.0069＋0.00167 ＝0.00857（kg/kg） となり、図中のＢ点まで加湿されることになるから飽和
効率は、 AB/AC＝22％ となる。Therefore, the absolute humidity x2 after the above heating is x2 = x1 + Δx = 0.0069 + 0.00167 = 0.00857 (kg / kg), and since it is humidified up to point B in the figure, the saturation efficiency is AB / AC = 22%.
飽和効率は理論上空気と水との接触交換率であるから水
表面積と風速によって決まり、吸い込み空気条件が変化
しても変わらない。しかし、実際には境界面での水表面
積と風速は特定しにくいので、機器の特性値として実験
により加湿材奥行き・長さに対する飽和効率を求めたと
ころ下表のような結果を得た。なお加湿材の垂下面間の
ピッチを5mm、風速を2m/sとした。Since the saturation efficiency is theoretically the contact exchange rate between air and water, it is determined by the water surface area and the wind speed, and does not change even if the intake air conditions change. However, since the water surface area and wind speed at the boundary surface are difficult to specify in practice, the saturation efficiency with respect to the depth and length of the humidifying material was obtained by experiments as the characteristic values of the equipment, and the results shown in the table below were obtained. The pitch between the vertical surfaces of the humidifying material was 5 mm and the wind speed was 2 m / s.
即ち、上記表より要求加湿量を出すためには加湿材奥行
き35mm、高さ300mm、ピッチ5mmにすればよいことがわか
る。また、この場合加湿材枚数は 830÷（５×２）＝83（枚） となる。この場合の空気抵抗は殆ど無いものと見做して
良い。 That is, it can be seen from the above table that the depth of the humidifying material is 35 mm, the height is 300 mm, and the pitch is 5 mm in order to obtain the required amount of humidification. In this case, the number of humidifying materials is 830 ÷ (5 × 2) = 83 (sheets). In this case, it can be considered that there is almost no air resistance.

腐食の点からステンレスが好ましい。If a 1 mm thick polyester non-woven fabric is used as the humidifying material, it is possible to have a water retention capacity of 0.1 g / cm 2 and a suction height of 100 mm or more. . As shown in Fig. 1, this humidifying material is used to make 2 × 38 mm square holes in the drip tank and the lower frame at a pitch of 5 mm, and the humidifying material is U-turned in the drip tank. Is skewered on the humidifying material, and then the lower frame is tightened with a screw to fix the humidifying material. If the square hole is made larger by 1mm toward the humidifying material, it will be easier to insert the humidifying material during manufacturing. In addition, since water does not separate from the humidifying material even if a considerably large amount of water is supplied due to the surface tension, it becomes easy to smoothly flow water and impurities that are larger than the amount of water retention. When the height is large, a comb-shaped separator may be inserted so that the adjacent humidifying materials do not stick to each other. Note that each of these materials is preferably stainless steel from the viewpoint of strength corrosion.
つぎに給水系を考えると、ごみづまり防止用のストレー
ナは市販のものでよく、これらは0.2mmくらいまでのゴ
ミを除去できる。このため給水パイプに設ける小孔はご
み同士の吸着によるつまりと製造性の点からφ0.5mm以
上にすればよい。また孔数は10mmピッチで83個となる。Next, considering the water supply system, strainers for preventing dust clogging can be commercially available, and these can remove dust up to about 0.2 mm. For this reason, the small holes provided in the water supply pipe may be set to 0.5 mm or more from the viewpoint of clogging caused by adsorption of dust particles and manufacturability. In addition, the number of holes is 83 at 10 mm pitch.
従って給水パイプの総内径は π/4×D2×Ｎ ＝3.14/4×0.52×83 ＝16（mm2） 即ち、φ4mmとなる。Therefore, the total inner diameter of the water supply pipe is π / 4 × D2 × N = 3.14 / 4 × 0.5 2 × 83 = 16 (mm 2 ) or φ 4 mm.
また市販されている減圧弁の二次側水圧は0.6kg/cm2が
多いので電磁弁と給水パイプのオリフィス径をφ4mm以
上とすれば、かなり圧力降下しても各小孔部には均等水
圧がかかり、給水パイプが長くても、また傾斜があって
も滴下量のばらつきは起こらないことがわかった。In addition, since the secondary side water pressure of a commercially available pressure reducing valve is often 0.6 kg / cm 2 , if the orifice diameter of the solenoid valve and the water supply pipe is φ4 mm or more, even if the pressure drops considerably, the uniform water pressure will be applied to each small hole. It was found that even if the water supply pipe was long and the water supply pipe was inclined, the drop amount did not vary.
但しこのオリフィス径で0.6kg/cm2の水圧で連続給水し
た場合、給水量が300/hにもなり、所要加湿量の100倍
の給水量となってしまう。給水量は６/hぐらいにした
いのであるから（不純物濃縮度を３倍以下にすればスケ
ールが析出しない）、タイマーにより給水時間を1/50に
すればよい。従って１時間当たりの総給水時間Ｔは Ｔ＝3600×（６÷300）＝72（秒） となる。However, if water is continuously supplied at a water pressure of 0.6 kg / cm 2 with this orifice diameter, the water supply rate will be 300 / h, which is 100 times the required humidification rate. Since we want to supply water at about 6 / h (scales will not precipitate if the impurity concentration is set to 3 times or less), the water supply time can be set to 1/50 by the timer. Therefore, the total water supply time T per hour is T = 3600 × (6 ÷ 300) = 72 (seconds).
即ち10分毎に12秒ずつ給水すば給水量を６/hぐらいに
できる。タイマーは10分のものと12秒のもの２個の組み
合わせにすれば繰り返しON−OFFさせることができる。
このようなタイマーは市販のものでよく、また設定時間
を可変するタイプも多いため、自由に給水量を設定でき
る。That is, if water is supplied for 12 seconds every 10 minutes, the amount of water supply can be about 6 / h. The timer can be repeatedly turned on and off by combining two timers of 10 minutes and 12 seconds.
Such a timer may be a commercially available one, and there are many types that can change the set time, so that the water supply amount can be freely set.

滴下位置のバラツキがあっても加湿材から外れることは
ない。もちろん給水パイプを加湿材に接触させてもよ
い。即ち一個の小孔からの滴下水は必ず一枚の加湿材を
濡らし、隣の加湿材を濡らすことはない。The water supply pipe has an outer diameter of 6 mm, and both the solenoid valve and the pipe are small and inexpensive. Considering excess wetting due to time variation of the humidifying material, the upper part of the humidifying material gets wet more than the water retention amount during water supply, so that the outer surface of the humidifying material becomes wet due to surface tension of water. However, even if it becomes wet for the entire surface water retention amount, or even if a humidifying material with a low water retention amount is used, the water retention amount is 0.05 g / cm 2 × 3.5 × 30 × 166 = 872 (g) for 10 minutes. The amount of humidification is 3600 x (1/6) = 600 (g), so there is no concern about drying and no scale or slime is generated. The amount of water retention can be adjusted by the thickness of the humidifying material, but with a normal thickness of 1 mm, there are many water absorbing materials of about 0.1 g / cm 2 . Also, the flat part of the top surface of the humidifying material is 5 mm x 30 mm
Since there is a size of, if you place a small hole in the center of this surface,
Even if the dropping position varies, it will not come off from the humidifying material. Of course, the water supply pipe may be brought into contact with the humidifying material. That is, the dripping water from one small hole always wets one humidifying material and does not wet the adjacent humidifying material.

湿負荷に見合った加湿運転ができる。In addition, three φ6mm water supply pipes are used, and each small hole pitch is 3
If it is set to 0 mm and water from the small holes of each water supply pipe does not wet the same humidifying material, the amount of humidification can be controlled by 1/3 by operating the water supply to each water supply pipe. Of course, the lower the humidity, the lower the temperature, and the lower the wind speed, the smaller the humidification amount.The air conditioner operates at low temperature and low wind speed when the heating load is low, and the humidification load decreases when the heating load is low. If the above-mentioned stage number control is added to this, the humidification operation suitable for the humidification load can be performed without stopping the water supply.

め初期能力を損なわないものとなるという効果がある。As described above, the humidifier and the humidifying system according to the present invention have the water supply pipe having the tip closed in the tank formed of the upper frame, and the humidifying material exposed in the tank through the small hole of the water supply pipe. Since water is made to drip onto the central flat part, it is possible to intermittently supply water to the humidifying material, and by concentrating the water when supplying water, sufficient humidification can be performed even with a small water supply amount. In addition, there is an effect that the precipitation of impurities in water does not occur, the proliferation of various bacteria does not occur, and the initial capacity is not impaired because the dirt of the air is purified and discharged.
