It is separated from the inflowing second air.
第2空気は、支持部材17の左側面に設けられた通風孔171を通過し、顕熱交換器10の上面に設けられた第2経路12の入口、すなわち第2経路12を構成する第2チャネル120夫々の開口端から、第2チャネル120夫々に流入する。

給水体13の一構成例を説明する。図2は、実施形態1に係る給水体13の一構成例を示す模式的斜視図である。給水体13は、平面視にて矩形状を成し(図3参照)、外郭となる箱体16を備える。給水体13は、第1経路11の経路方向に対し直角となるように位置させて、顕熱交換器10の上方に載置されている。給水体13は、上述のとおり支持部材17の上面に載置されることにより、顕熱交換器10の上方に支持されて設けられている。給水体13が載置されている上面の領域は、支持部材17の右側面側に設けられている。
An example of the configuration of the water supply body 13 will be described. FIG. 2 is a schematic perspective view showing a configuration example of the water supply body 13 according to the first embodiment. The water supply body 13 has a rectangular shape in a plan view (see FIG. 3), and includes a box body 16 as an outer shell. The water supply body 13 is positioned above the sensible heat exchanger 10 so as to be perpendicular to the path direction of the first path 11. The water supply body 13 is provided so as to be supported above the sensible heat exchanger 10 by being placed on the upper surface of the support member 17 as described above. The area on the upper surface on which the water supply body 13 is placed is provided on the right side surface side of the support member 17.
支持部材17の下方には、第1経路11が位置しており、支持部材17の右側面の側に設けられている給水体13は、第1空気の流れ方向において、第1経路11の下流側に設けられている。給水体13は、顕熱交換器10の第2経路12の入口上方の第1経路11の下流側に位置している。すなわち、給水体13は、第1経路11の入口よりも出口の側に偏倚させて、第2経路12の入口上方に設けられている。顕熱交換器10の第1経路11において、給水体13に近接するほど、後述する第1タンク71(図8参照)から供給される水によって温度が低下する。第1経路11の入口における第1空気の温度は、被空調空間の室温に相当するものであり、第1経路11内にある第1空気の温度分布において、最も高い温度となる。これに対し、第1経路11の下流側、すなわち第1経路11の出口側に偏倚させて給水体13を設けることにより、第1経路11の全域に亘って、第1空気と水との温度差を大きくとることができ、第1空気に対する冷却効率を向上させることができる。
The first path 11 is located below the support member 17, and the water supply body 13 provided on the right side of the support member 17 is downstream of the first path 11 in the flow direction of the first air. It is provided on the side. The water supply body 13 is located on the downstream side of the first path 11 above the inlet of the second path 12 of the sensible heat exchanger 10. That is, the water supply body 13 is provided above the inlet of the second path 12 so as to be biased toward the outlet side of the inlet of the first path 11. In the first path 11 of the sensible heat exchanger 10, the closer to the water supply body 13, the lower the temperature is due to the water supplied from the first tank 71 (see FIG. 8) described later. The temperature of the first air at the inlet of the first path 11 corresponds to the room temperature of the air-conditioned space, and is the highest temperature in the temperature distribution of the first air in the first path 11. On the other hand, by providing the water supply body 13 on the downstream side of the first path 11, that is, on the outlet side of the first path 11, the temperature of the first air and water covers the entire area of the first path 11. The difference can be made large, and the cooling efficiency with respect to the first air can be improved.
図3は、給水体13の一構成例を示す模式的平面図である。図4は、給水体13の一構成例を示す模式的下面図である。図5は、給水体13の一構成例を示す模式的側面図である。給水体13は、平面視にて矩形状を成し外郭となる箱体16を備え、例えば樹脂製である。給水体13の上面161には、円筒状の水受部14と、水受部14から放射状に延びる複数のリブ150が設けられている。
FIG. 3 is a schematic plan view showing a configuration example of the water supply body 13. FIG. 4 is a schematic bottom view showing a configuration example of the water supply body 13. FIG. 5 is a schematic side view showing a configuration example of the water supply body 13. The water supply body 13 includes a box body 16 that has a rectangular shape in a plan view and serves as an outer shell, and is made of, for example, resin. The upper surface 161 of the water supply body 13 is provided with a cylindrical water receiving portion 14 and a plurality of ribs 150 extending radially from the water receiving portion 14.
水受部14は、当該上面161における長手方向において、一方に偏倚して設けられている。水受部14には、第2供給水路82(図8参照)が連通される。第2供給水路82は、後述する第1タンク71(図8参照)から延設された供給水路8(図8参照)から分岐される水路である。上面161は、水受部14近傍の面は水平に形成され、所定位置から後方に向かうほど下方に向かって傾斜している。本実施形態では、図5に示すように左側の側面160から見ると、上面161は、前方端部から5番目の縦リブ152までが平面形状をしており、5番目の縦リブ152から後方端部までが後方に向かうほど低くなるように傾斜している。水受部14近傍の面が水平に形成されることにより、水受部14の中央に滴下された水が、同心円を描き各流水路15に均等に分流される。さらに、水受部14から離れた位置から傾斜していることにより、分流された水は流水路15内に滞留することなく、第2チャネル120夫々に流入する。図3に示されるように、流水路15は、水受部14から離れるほど流路幅が広く形成されているため、上面161が水平面の場合、分流された水の流速は下流に進むほど緩やかになってしまうことが考えられる。しかし、上面161に傾斜があることにより、流速を損なわず、第2チャネル120夫々に分流された水を流入することが可能になる。
The water receiving portion 14 is provided unevenly on one side in the longitudinal direction on the upper surface 161. A second supply channel 82 (see FIG. 8) communicates with the water receiving unit 14. The second supply water channel 82 is a water channel branched from the supply water channel 8 (see FIG. 8) extending from the first tank 71 (see FIG. 8) described later. The surface of the upper surface 161 near the water receiving portion 14 is formed horizontally, and is inclined downward from a predetermined position toward the rear. In the present embodiment, when viewed from the left side surface 160 as shown in FIG. 5, the upper surface 161 has a planar shape from the front end to the fifth vertical rib 152, and is rearward from the fifth vertical rib 152. It is inclined so that it becomes lower toward the rear to the end. By forming the surface in the vicinity of the water receiving portion 14 horizontally, the water dropped in the center of the water receiving portion 14 draws concentric circles and is evenly distributed to each flow channel 15. Further, since the water is inclined from a position away from the water receiving portion 14, the separated water flows into each of the second channels 120 without staying in the flowing water channel 15. As shown in FIG. 3, since the flow path width of the water flow channel 15 is formed wider as the distance from the water receiving portion 14 increases, when the upper surface 161 is a horizontal plane, the flow velocity of the divided water becomes gentler as it goes downstream. It is conceivable that it will become. However, since the upper surface 161 has an inclination, it is possible to flow the separated water into each of the second channels 120 without impairing the flow velocity.
第2供給水路82から供給された水は、水受部14にて受けられた後、当該水受部14から放射状に延びる複数のリブ150沿って分流され、分流された水は、顕熱交換器10の第2経路12の内部に滴下される。すなわち、給水体13は、顕熱交換器10の第2経路12を構成する複数の第2チャネル120夫々に、第1タンク71から供給された水を散水する散水部として機能する。
The water supplied from the second supply channel 82 is received by the water receiving unit 14, and then is divided along a plurality of ribs 150 radially extending from the water receiving unit 14, and the separated water exchanges sensible heat. It is dropped inside the second path 12 of the vessel 10. That is, the water supply body 13 functions as a watering unit that sprinkles the water supplied from the first tank 71 to each of the plurality of second channels 120 constituting the second path 12 of the sensible heat exchanger 10.
水受部14の外周面から放射状に延びる複数のリブ150夫々は、等間隔のピッチで設けられており、当該ピッチは、例えば6mmである。ピッチが等間隔に形成されることにより均等に分流される効果を高めることができる。複数のリブ150夫々は、水受部14から上面161における長辺側の縁部に向かって、一回以上折り曲げられることにより、L字状、コの字状(C字状)又はクランク状に形成されている。
The plurality of ribs 150 extending radially from the outer peripheral surface of the water receiving portion 14 are provided at equal intervals, and the pitch is, for example, 6 mm. By forming the pitches at equal intervals, the effect of evenly splitting can be enhanced. Each of the plurality of ribs 150 is bent one or more times from the water receiving portion 14 toward the edge on the long side of the upper surface 161 to form an L-shape, a U-shape (C-shape), or a crank shape. It is formed.
水受部14から放射状に延びる複数のリブ150において、隣接する2つのリブ150によって形成される溝により、流水路15が形成される。すなわち、給水体13の上面161における流水路15夫々は、給水体13の上面161に設けられた隣接する2つのリブ150によって形成される溝により構成される。水受部14によって受けられた水は、流水路15、すなわち隣接する2つのリブ150によって形成される溝に沿って、上面161における長辺側の縁部に向かって流れるものとなる。
In the plurality of ribs 150 extending radially from the water receiving portion 14, the water flow channel 15 is formed by the grooves formed by the two adjacent ribs 150. That is, each of the flow channels 15 on the upper surface 161 of the water supply body 13 is composed of grooves formed by two adjacent ribs 150 provided on the upper surface 161 of the water supply body 13. The water received by the water receiving portion 14 flows toward the long side edge portion on the upper surface 161 along the flow channel 15, that is, the groove formed by the two adjacent ribs 150.
隣り合う2つのリブ150による角度は、水受部14の外周面から延設されている複数のリブ150の全てにおいて等しい角度となるようにしてある。従って、水受部14が受け付けた水を、流水路15夫々に対し散水して分配するにあたり、流水路15夫々における分配水量の差異が大きくなることを抑制することができる。
The angle between the two adjacent ribs 150 is set to be the same for all of the plurality of ribs 150 extending from the outer peripheral surface of the water receiving portion 14. Therefore, when the water received by the water receiving unit 14 is sprinkled and distributed to each of the flowing water channels 15, it is possible to suppress a large difference in the amount of distributed water in each of the flowing water channels 15.
複数のリブ150夫々は、上面161の長辺側の縁部に近接した地点にて、二本の平行なリブ150に分岐されている。すなわち、複数のリブ150は、基端となる水受部14から、上面161の長辺側の縁部に延設され、当該縁部に近接した地点に位置する端部151で、2つに分岐している。2つ分岐されたリブ150の端部151の夫々には、縦リブ152が延設されている。縦リブ152は、給水体13の上面161から側面160に向かって折り曲げられて、当該側面160の上方から下方に向けて延設されている。縦リブ152は、給水体13の側面160において上下に延設される一対の平行な二本のリブが構成されている。
Each of the plurality of ribs 150 is branched into two parallel ribs 150 at a point close to the edge on the long side of the upper surface 161. That is, the plurality of ribs 150 extend from the water receiving portion 14 which is the base end to the edge portion on the long side side of the upper surface 161 and are formed into two at the end portion 151 located at a point close to the edge portion. It is branched. Vertical ribs 152 extend to each of the ends 151 of the two branched ribs 150. The vertical rib 152 is bent from the upper surface 161 of the water supply body 13 toward the side surface 160, and extends from the upper side to the lower side of the side surface 160. The vertical rib 152 is composed of a pair of parallel ribs extending vertically on the side surface 160 of the water supply body 13.
給水体13の上面161において、水受部14が設けられている側の短辺とは逆の短辺の側に、V字状の切欠き部162が設けられている。水受部14から、短辺の側に向かって延設されたリブのうち、一部のリブ150は、当該V字状の切欠き部162によって形成される内壁面に向かって折り曲げられ、縦リブ152となる。縦リブ152は当該内壁面の上方から下方に向けて延設されている。
On the upper surface 161 of the water supply body 13, a V-shaped notch 162 is provided on the side opposite to the short side on the side where the water receiving portion 14 is provided. Of the ribs extending from the water receiving portion 14 toward the short side, some of the ribs 150 are bent toward the inner wall surface formed by the V-shaped notch 162 and are vertically bent. It becomes the rib 152. The vertical rib 152 extends from above to below the inner wall surface.
長辺側となる夫々の側面160及び、V字状の切欠き部162によって形成される内壁面には、平行な2本の縦リブ152が設けられる。平行な2本の縦リブ152は、前後方向に等間隔となるように並設されている。長辺側となる夫々の側面160において、一方の側面160に設けられた縦リブ152と、他方の側面160に設けられた縦リブ152とは、側面視にて重ならないように、図3に示すように千鳥状に設けられている。すなわち一例として図5に示す左側面視にて、一方の側面160に設けられた縦リブ152と当該縦リブ152に隣接する縦リブ152との間に、他方の側面160に設けられた縦リブ152が位置するように、夫々の側面160の縦リブ152が設けられている。同様にV字状の切欠き部162によって形成される内壁面においても、互いに向かい夫々の内壁面に設けられた夫々の縦リブ152は、千鳥状に設けられている。
Two parallel vertical ribs 152 are provided on the side surfaces 160 on the long side and the inner wall surface formed by the V-shaped notch 162. Two parallel vertical ribs 152 are arranged side by side at equal intervals in the front-rear direction.

FIG. 6 is an explanatory diagram schematically showing the air flow in the heat exchanger unit 1. FIG. 7 is an explanatory diagram illustrating a main part of the water supply body 13 in the heat exchanger unit 1. In FIG. 7, only a part of the sensible heat exchanger 10 is shown. The first air and the second air flow from the same side surface side (left side side side) of the heat exchanger unit 1 toward the heat exchanger unit 1. As described above, the first air flows into the inside of the sensible heat exchanger 10 from the inlet of the first path 11 located on the left side surface of the sensible heat exchanger 10, that is, the opening end of each of the first channels 110. The second air passes through the ventilation hole 171 formed on the left side surface of the support member 17 provided so as to cover the upper surface of the sensible heat exchanger 10, and then the second path located on the upper surface of the sensible heat exchanger 10. It flows into the inside of the sensible heat exchanger 10 from the inlet of 12, that is, the open end of each of the second channels 120. The arrow representing the second air in FIG. 6 indicates that the second air flows in from the inlet of the second path 12 on the upper surface of the sensible heat exchanger 10 and flows downward, and is on the lower surface of the sensible heat exchanger 10. It shows how the second air flows out from the outlet of the two paths 12 and flows backward.
縦リブ152は、給水体13の側面160において上下に延設される一対となる平行な二本のリブにより構成されており、顕熱交換器10の第2経路12を構成する第2チャネル120夫々に対応して設けられている。図7に示すとおり、縦リブ152夫々と、第2経路12を構成する第2チャネル120夫々とが位置合わせされた状態で、給水体13は、顕熱交換器10の上部に載置されている。縦リブ152を構成する二本のリブの先端部夫々が、第2チャネル120夫々の開口端に重なるように給水体13は、顕熱交換器10の上部に載置されている。縦リブ152を構成する二本のリブ間の距離は、第1経路11を構成する第1チャネル110のピッチ幅よりも大きくしてある。従って、縦リブ152を構成する二本のリブの間に第1経路11を構成する第1チャネル110夫々が位置するように、給水体13は、顕熱交換器10の上部に載置されている。
The vertical rib 152 is composed of a pair of two parallel ribs extending vertically on the side surface 160 of the water supply body 13, and is a second channel 120 constituting the second path 12 of the sensible heat exchanger 10. It is provided for each. As shown in FIG. 7, the water supply body 13 is placed on the upper part of the sensible heat exchanger 10 in a state where the vertical ribs 152 and the second channels 120 constituting the second path 12 are aligned with each other. There is. The water supply body 13 is placed on the upper part of the sensible heat exchanger 10 so that the tips of the two ribs constituting the vertical rib 152 overlap with the opening ends of the second channels 120, respectively. The distance between the two ribs forming the vertical rib 152 is made larger than the pitch width of the first channel 110 forming the first path 11. Therefore, the water supply body 13 is placed on the upper part of the sensible heat exchanger 10 so that the first channels 110 forming the first path 11 are located between the two ribs forming the vertical ribs 152. There is.
水受部14から分流された水は、給水体13の上面161に放射状に設けられたリブ150と当該リブ150に隣接する間、すなわち隣接する2つのリブ150により構成される流水路15を流れる。給水体13の上面161から、側面160又は、V字状の切欠き部162によって形成される内壁面に沿って下方に流れ落ちる水は、縦リブ152を構成する二本のリブの外面側を伝って流れ落ちる。縦リブ152を構成する二本のリブ夫々は、第2経路12を構成する複数の第2チャネル120において、隣接する第2チャネル120夫々の開口端に位置するようにしてあるので、縦リブ152の外面側を伝って流れ落ちる水を、第2チャネル120夫々の開口端に滴下することができる。
The water separated from the water receiving portion 14 flows through a flow channel 15 composed of ribs 150 radially provided on the upper surface 161 of the water supply body 13 and adjacent to the ribs 150, that is, two adjacent ribs 150. .. Water flowing downward from the upper surface 161 of the water supply body 13 along the inner wall surface formed by the side surface 160 or the V-shaped notch 162 travels on the outer surface side of the two ribs constituting the vertical rib 152. And run down. Since each of the two ribs constituting the vertical rib 152 is located at the opening end of each of the adjacent second channel 120 in the plurality of second channels 120 constituting the second path 12, the vertical rib 152 is formed. The water flowing down along the outer surface side of the second channel 120 can be dropped onto the opening end of each of the second channels 120.
上面161に設けられるリブ150間のピッチを確保するため、側面160に形成することができる縦リブ152の個数も制限される。従って、一方の側面160の側にて、水が滴下されない第2経路12が生じる。これに対し、夫々の側面160に設けられる縦リブ152は、千鳥状を成す位置に形成してあるため、一方の側面160の側にて水が滴下されなかった第2経路12に対し、他方の側面160に設けられている縦リブ152によって当該第2経路12に水を滴下することができる。同様にV字状の切欠き部162によって形成される内壁面夫々において、千鳥状を成す位置に設けられた縦リブ152によって、対応する第2経路12夫々に水を滴下することができる。このように千鳥状を成す位置に設けられた縦リブ152によって、上面161に設けられるリブ150間のピッチを十分に確保しつつ、顕熱交換器10における全ての第2経路12に、第1タンク71から供給された水を滴下し、顕熱交換器10における冷却能力を向上させることができる。
The number of vertical ribs 152 that can be formed on the side surface 160 is also limited in order to secure the pitch between the ribs 150 provided on the upper surface 161. Therefore, on the side of one side surface 160, a second path 12 in which water is not dropped is generated. On the other hand, since the vertical ribs 152 provided on the respective side surfaces 160 are formed at staggered positions, the other is to the second path 12 where water is not dropped on one side surface 160 side. Water can be dropped on the second path 12 by the vertical rib 152 provided on the side surface 160 of the above. Similarly, in each of the inner wall surfaces formed by the V-shaped notch 162, water can be dropped into each of the corresponding second paths 12 by the vertical ribs 152 provided at the staggered positions. The vertical ribs 152 provided at the staggered positions in this way ensure a sufficient pitch between the ribs 150 provided on the upper surface 161 and are used for the first in all the second paths 12 in the sensible heat exchanger 10. The water supplied from the tank 71 can be dropped to improve the cooling capacity of the sensible heat exchanger 10.

第1供給水路81から供給された水は、気化フィルタ21の上部に設けられている第1給水部211によって一旦、保水され、第1給水部211に設けられた給水孔から気化フィルタ21に滴下され、気化フィルタ21内に浸透する。第2供給水路82から供給された水は、顕熱交換器10の上部に設けられている給水体13を介して、顕熱交換器10の第2経路12の内部に滴下される。
The water supplied from the first supply water channel 81 is once retained by the first water supply unit 211 provided in the upper part of the vaporization filter 21, and then dropped onto the vaporization filter 21 from the water supply hole provided in the first water supply unit 211. And penetrates into the vaporization filter 21. The water supplied from the second supply water channel 82 is dropped into the inside of the second path 12 of the sensible heat exchanger 10 via the water supply body 13 provided in the upper part of the sensible heat exchanger 10.
第1タンク71に設けられたポンプ101によって、第1タンク71から気化フィルタ21及び顕熱交換器10に搬送され、気化フィルタ21及び顕熱交換器10にて気化せず液体の状態の残った水は、重力によって第1タンク71に還流される。すなわち、第1タンク71、供給水路8、冷却ユニット2、及び回収水路9による水の循環水路が形成される。
It was conveyed from the first tank 71 to the vaporization filter 21 and the sensible heat exchanger 10 by the pump 101 provided in the first tank 71, and was not vaporized by the vaporization filter 21 and the sensible heat exchanger 10 and remained in a liquid state. The water is returned to the first tank 71 by gravity. That is, a water circulation channel is formed by the first tank 71, the supply channel 8, the cooling unit 2, and the recovery channel 9.
供給水路8は、冷却ユニット2に含まれる気化フィルタ21及び熱交換器ユニット1に応じて、第1供給水路81及び第2供給水路82に分岐される。回収水路9は、冷却ユニット2に含まれる気化フィルタ21及び熱交換器ユニット1に応じて、第1回収水路91及び第2回収水路92を備える。従って、循環水路は、第1供給水路81、気化フィルタ21及び第1回収水路91による気化フィルタ21系水路と、第2供給水路82、熱交換器ユニット1の第2経路12、第2回収水路92による熱交換器ユニット1系水路とが並列に構成された水路を含む。
The supply water channel 8 is branched into a first supply water channel 81 and a second supply water channel 82 according to the vaporization filter 21 and the heat exchanger unit 1 included in the cooling unit 2. The recovery water channel 9 includes a first recovery water channel 91 and a second recovery water channel 92 according to the vaporization filter 21 and the heat exchanger unit 1 included in the cooling unit 2. Therefore, the circulation water channels include the vaporization filter 21 system water channel by the first supply water channel 81, the vaporization filter 21 and the first recovery water channel 91, the second supply water channel 82, the second path 12 of the heat exchanger unit 1, and the second recovery water channel. Includes a water channel configured in parallel with the heat exchanger unit 1 system water channel according to 92.
ポンプ101の駆動によって搬送される水の単位時間あたりの体積流量において、気化フィルタ21系水路である第1供給水路81の体積流量は、熱交換器ユニット1系水路である第2供給水路82の体積流量よりも少なくしてある。例えば、第1供給水路81の体積流量は0.3L/minとし、第2供給水路82の体積流量は3L/minとして、第1供給水路81の体積流量は、第2供給水路82の体積流量の1/10とするものであってもよい。これにより、第1空気と共に被空調空間に吹き出される水蒸気の量を抑制しつつ、顕熱交換器10において顕熱によって第2空気を冷却するための水量を多くすることができ、冷却ユニット2における冷却効率を更に向上させることができる。
In the volume flow rate per unit time of the water conveyed by the drive of the pump 101, the volumetric flow rate of the first supply water channel 81, which is the vaporization filter 21 system water channel, is the volume flow rate of the second supply water channel 82, which is the heat exchanger unit 1 system water channel. It is less than the volumetric flow rate. For example, the volumetric flow rate of the first supply channel 81 is 0.3 L / min, the volumetric flow rate of the second supply channel 82 is 3 L / min, and the volumetric flow rate of the first supply channel 81 is the volumetric flow rate of the second supply channel 82. It may be 1/10 of the above. As a result, it is possible to increase the amount of water for cooling the second air by sensible heat in the sensible heat exchanger 10 while suppressing the amount of water vapor blown out to the air-conditioned space together with the first air, and the cooling unit 2 The cooling efficiency in the above can be further improved.
空調機100は、被空調空間の空気を吸込口3から吸込し、吸込された吸込空気は、吸込流路32及び集塵フィルタ31を通過して、熱交換器ユニット1に流入する。吸込流路32の出口に対応して、熱交換器ユニット1の第1経路11(SA:給気側経路)及び第2経路12(EA:排気側経路)の入口が、熱交換器ユニット1の側面に設けられており、吸込空気は、第1経路11を流れる第1空気(SA)と、第2経路12を流れる第2空気(EA)とに分流される。
The air conditioner 100 sucks the air in the air-conditioned space from the suction port 3, and the sucked air passes through the suction flow path 32 and the dust collection filter 31 and flows into the heat exchanger unit 1. Corresponding to the outlet of the suction flow path 32, the inlets of the first path 11 (SA: air supply side path) and the second path 12 (EA: exhaust side path) of the heat exchanger unit 1 are the heat exchanger unit 1. The suction air is divided into a first air (SA) flowing through the first path 11 and a second air (EA) flowing through the second path 12.
第2経路12には、顕熱交換器10の上部に設けられた給水体13を介して、第1タンク71から供給された水が滴下される。すなわち、第2経路12は、第2空気と、給水体13から滴下された水とが、混在する状態となる。第1タンク71に貯水されている水は、気化フィルタ21から回収した水であり、気化熱により冷却されている水である。従って、第1タンク71から供給された水の水温は、第2経路12に流入した直後の第2空気の温度よりも低い。第2空気は、給水体13から滴下された水と熱交換する。すなわち当該水によって冷却される。又、前述のとおり給水体13から滴下された水は、第2経路12を構成する第2チャネル120夫々に分配されて、当該第2チャネル120の内部に滴下するため、第2空気に接する水の表面積は、増加する。これにより、給水体13から滴下された水の一部は気化し、当該気化熱によっても、第2空気は冷却される。
The water supplied from the first tank 71 is dropped onto the second path 12 via the water supply body 13 provided above the sensible heat exchanger 10. That is, in the second path 12, the second air and the water dropped from the water supply body 13 are mixed. The water stored in the first tank 71 is the water recovered from the vaporization filter 21 and is cooled by the heat of vaporization. Therefore, the water temperature of the water supplied from the first tank 71 is lower than the temperature of the second air immediately after flowing into the second path 12. The second air exchanges heat with the water dropped from the water supply body 13. That is, it is cooled by the water. Further, as described above, the water dropped from the water supply body 13 is distributed to each of the second channels 120 constituting the second path 12, and is dropped into the inside of the second channel 120, so that the water is in contact with the second air. Surface area increases. As a result, a part of the water dropped from the water supply body 13 is vaporized, and the second air is also cooled by the heat of vaporization.
顕熱交換器10の第1経路11に流れる第1空気と、第2経路12に流れる第2空気とは、直交流を形成しており、第1空気と第2空気との間で顕熱交換がされる。上述のとおり、第2経路12に流れる第2空気は、第1タンク71から供給された水によって冷却されており、第1空気は、第1タンク71から供給された水によって冷却された第2空気によって、冷却される。
The first air flowing in the first path 11 of the sensible heat exchanger 10 and the second air flowing in the second path 12 form a orthogonal flow, and the sensible heat is generated between the first air and the second air. It will be exchanged. As described above, the second air flowing through the second path 12 is cooled by the water supplied from the first tank 71, and the first air is cooled by the water supplied from the first tank 71. It is cooled by air.
顕熱交換器10の第1経路11を通過した第1空気は、顕熱交換器10から第1吹出口4までの第1流路41に流入する。当該第1流路41において、顕熱交換器10の下流側には気化フィルタ21が設けられており、第1空気は気化フィルタ21を通過する。
The first air that has passed through the first path 11 of the sensible heat exchanger 10 flows into the first flow path 41 from the sensible heat exchanger 10 to the first outlet 4. In the first flow path 41, a vaporization filter 21 is provided on the downstream side of the sensible heat exchanger 10, and the first air passes through the vaporization filter 21.
気化フィルタ21には、気化フィルタ21の上部に設けられた第1給水部211を介して、第1タンク71から供給された水が滴下される。第1流路41内は負圧に保たれているので、第1タンク71から供給された水は、第1給水部211の底面に設けられた給水孔から気化フィルタ21の内部に吸い込まれ、気化フィルタ21内に浸透する。気化フィルタ21に浸透した水は、第1空気が気化フィルタ21を通過することにより気化が促進され、気化、すなわち蒸発して水蒸気となって第1空気に含有される。当該気化熱により、第1空気は冷却され、第1空気の温度は低下する。冷却された第1空気は、第1ファン61によって第1吹出口4から、給気(SA)として被空調空間に吹き出される。
Water supplied from the first tank 71 is dropped onto the vaporization filter 21 via the first water supply unit 211 provided above the vaporization filter 21. Since the inside of the first flow path 41 is maintained at a negative pressure, the water supplied from the first tank 71 is sucked into the inside of the vaporization filter 21 from the water supply hole provided on the bottom surface of the first water supply unit 211. It penetrates into the vaporization filter 21. The water that has permeated the vaporization filter 21 is vaporized by the passage of the first air through the vaporization filter 21, and is vaporized, that is, evaporated to become water vapor and contained in the first air. The heat of vaporization cools the first air and lowers the temperature of the first air. The cooled first air is blown out from the first outlet 4 by the first fan 61 into the air-conditioned space as supply air (SA).
このような構成とすることにより、給気(SA)として被空調空間に吹き出される第1空気に対し、顕熱交換器10による一次冷却、及び気化フィルタ21による二次冷却を含む2段階の冷却を行うことができる。従って、例えば、気化フィルタ21のみを用いる直接気化方式と比較して、第1空気の温度を更に低下させることができる。このとき、第1給水部211は、給水体13に置き換えてもよい。
With such a configuration, the first air blown out to the air-conditioned space as air supply (SA) has two stages including primary cooling by the sensible heat exchanger 10 and secondary cooling by the vaporization filter 21. Cooling can be done. Therefore, for example, the temperature of the first air can be further lowered as compared with the direct vaporization method using only the vaporization filter 21. At this time, the first water supply unit 211 may be replaced with the water supply body 13.
顕熱交換器10の第2経路12に流入した第2空気は、給水体13から滴下して給水された水が混合され、顕熱交換器10の下方に位置する第2経路12の出口に向かって、搬送される。第2経路12は、第1経路11との直交流が形成される領域において、顕熱交換器10の上方から下方に向かって延設されているため、給水体13から給水された水が混合した第2空気は、顕熱交換器10の上方から下方に向かって流れる。
The second air that has flowed into the second path 12 of the sensible heat exchanger 10 is mixed with the water that has been dropped from the water supply body 13 and supplied to the outlet of the second path 12 located below the sensible heat exchanger 10. It is transported toward. Since the second path 12 extends from the upper side to the lower side of the sensible heat exchanger 10 in the region where the orthogonal flow with the first path 11 is formed, the water supplied from the water supply body 13 is mixed. The generated second air flows from the upper side to the lower side of the sensible heat exchanger 10.
顕熱交換器10の第2経路12の出口の下流側には、ドレンパン103が設けられており、ドレンパン103から第2吹出口5までの第2流路51は、ドレンパン103から上方に向かって延設されている。第2流路51は、図8の奥行き方向である後方向に形成されている。従って、給水体13から給水された水が混合した第2空気は、顕熱交換器10の第2経路12の出口から流出した後、ドレンパン103がある地点を最下点として、上下に折り返して流れるものとなる。すなわち、顕熱交換器10の第2経路12を含む第2流路51は、顕熱交換器10の上方から下方に延び、ドレンパン103が位置する場所を通過後、上方に向かって延設された上下方向の折り返し部を含む。
A drain pan 103 is provided on the downstream side of the outlet of the second path 12 of the sensible heat exchanger 10, and the second flow path 51 from the drain pan 103 to the second outlet 5 is directed upward from the drain pan 103. It has been extended. The second flow path 51 is formed in the rear direction, which is the depth direction of FIG. Therefore, the second air mixed with the water supplied from the water supply body 13 flows out from the outlet of the second path 12 of the heat exchanger 10, and then is folded up and down with the point where the drain pan 103 is located as the lowest point. It will flow. That is, the second flow path 51 including the second path 12 of the sensible heat exchanger 10 extends downward from above the sensible heat exchanger 10, passes through the place where the drain pan 103 is located, and then extends upward. Includes a folded part in the vertical direction.
給水体13から給水された水が混合した第2空気が、当該折り返し部を通過する際、すなわち下方への流れ方向から、上方への流れ方向に変化するにあたり、遠心力が発生する。第2空気と共に流れる水は、空気よりも比重が大きいため、遠心力により、折り返し部の外周側に偏ることにより、第2空気から分離、すなわち気液分離されるものとなる。
Centrifugal force is generated when the second air mixed with the water supplied from the water supply body 13 passes through the folded-back portion, that is, when it changes from the downward flow direction to the upward flow direction. Since the water flowing together with the second air has a higher specific gravity than the air, it is separated from the second air, that is, gas-liquid separated by being biased toward the outer peripheral side of the folded-back portion by centrifugal force.
第2空気から分離(気液分離)された水は、ドレンパン103に一旦、保水され、ドレンパン103の下部に設けられた第2回収水路92を介して、第1タンク71に回収される。なお、顕熱交換器10の第2経路12の内壁面に付着した水も、重力によって第2経路12の出口に移動し、当該出口から滴下することにより、ドレンパン103に保水され、第2回収水路92を介して、第1タンク71に回収される。
The water separated from the second air (gas-liquid separation) is temporarily retained in the drain pan 103, and is recovered in the first tank 71 via the second recovery water channel 92 provided in the lower part of the drain pan 103. The water adhering to the inner wall surface of the second path 12 of the sensible heat exchanger 10 also moves to the outlet of the second path 12 due to gravity, and by dropping from the outlet, the water is retained in the drain pan 103 and recovered second. It is collected in the first tank 71 via the water channel 92.
顕熱交換器10の第2経路12における上方から下方に延設される部分、第2経路12の出口の下方に設けられたドレンパン103、及びドレンパン103から上方に向かって延設される第2流路51によって、給水体13から給水された水が混合した第2空気から、当該水を分離する気液分離機構が構成される。当該気液分離機構によって、第2空気から水を分離することにより、当該第2空気の絶対湿度が増加することを抑制することができる。
A portion of the sensible heat exchanger 10 extending upward from above in the second path 12, a drain pan 103 provided below the outlet of the second path 12, and a second extending upward from the drain pan 103. The flow path 51 constitutes a gas-liquid separation mechanism that separates the water from the second air mixed with the water supplied from the water supply body 13. By separating water from the second air by the gas-liquid separation mechanism, it is possible to suppress an increase in the absolute humidity of the second air.
ドレンパン103を通過した第2空気は、ドレンパン103から第2吹出口5までの第2流路51に流入する。第2流路51は、例えば、顕熱交換器10の側面と、当該側面に対向する筐体104の内面との間に設けられており、第2空気は、第2流路51を介して、ドレンパン103から、ファンモータ6及び第2ファン62が載置されているファン室に搬送される。すなわちファンモータ6は、第2流路51の途中に設けられているため、第2空気によって冷却される。ファンモータ6は、気液分離機構の下流側に設けられているため、水が分離された後の第2空気によって、当該ファンモータ6を効率的に冷却することができる。ファンモータ6を冷却した第2空気は、第2吹出口5から排気として吹き出される。
The second air that has passed through the drain pan 103 flows into the second flow path 51 from the drain pan 103 to the second outlet 5. The second flow path 51 is provided between, for example, the side surface of the sensible heat exchanger 10 and the inner surface of the housing 104 facing the side surface, and the second air flows through the second flow path 51. , The drain pan 103 is conveyed to the fan chamber in which the fan motor 6 and the second fan 62 are placed. That is, since the fan motor 6 is provided in the middle of the second flow path 51, it is cooled by the second air. Since the fan motor 6 is provided on the downstream side of the gas-liquid separation mechanism, the fan motor 6 can be efficiently cooled by the second air after the water is separated. The second air that has cooled the fan motor 6 is blown out as exhaust from the second outlet 5.
本実施形態にて示すとおり、給水体及び顕熱交換器を含む熱交換器ユニット1は、第1空気の下流側に給水体を配置したので、顕熱交換器に供給された水により冷却された第2空気によって、冷却された第1空気を給気として被空調空間に吹き出すことができる。
As shown in the present embodiment, since the heat exchanger unit 1 including the water supply body and the sensible heat exchanger has the water supply body arranged on the downstream side of the first air, it is cooled by the water supplied to the sensible heat exchanger. The second air can be used to blow the cooled first air into the air-conditioned space as supply air.
今回開示された実施形態はすべての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は、上述した意味ではなく、特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。
The embodiments disclosed this time should be considered to be exemplary in all respects and not restrictive. The scope of the present invention is indicated by the scope of claims, not the meaning described above, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
