- region 63c are each shown.
- the flow of air during the humidifying operation will be described.
- the humidification operation is performed in combination with the heating operation. For this reason, during the humidifying operation, the compressor 31 and the outdoor fan 39 are driven.
- the humidifying rotor 63 is rotated at a predetermined rotational speed by the power of the rotor drive motor 65, and the heater 71 and the turbo fan 75 are driven. Since the humidification rotor 63 rotates, the moisture adsorbed by the humidification rotor 63 due to moisture absorption in the moisture absorption area 63a is carried to the moisture release area 63b as the humidification rotor 63 rotates, and the moisture release in the moisture release area 63b. The moisture adsorbed by the air is desorbed, so that the air around the moisture release region 63b is humidified.
- the humidification rotor 63 of the present embodiment rotates counterclockwise when viewed from the front, and when the portion functioning as the moisture absorption region 63a rotates and comes to a position facing the heater support member 74, the moisture release region 63b. Function as.
- the turbo fan 75 since the turbo fan 75 is driven during the humidification operation, the air flow from the air-conditioning room outdoor unit 30 to the air-conditioning indoor unit 20, that is, the outside air sucked from the suction port 72 passes through the humidification rotor 63 and the heater 71. Thus, an air flow blown out to the air supply duct 18 is generated. More specifically, the outside air sucked from the suction port 72 first circulates in front of the humidification rotor 63 and reaches the heater 71 through the humidification rotor 63 from the front to the rear. The outside air reaching the heater 71 passes through the casing of the heater 71. At this time, the outside air is heated by the heater 71.
- the air that has passed through the housing of the heater 71 proceeds to the moisture release region 63b of the humidification rotor 63, and passes through the moisture release region 63b of the humidification rotor 63 from the rear toward the front. At this time, the moisture release area 63b of the humidification rotor 63 is exposed to the air whose temperature has been increased by the heater 71 to release moisture. Then, the air that has passed through the moisture release region 63 b of the humidification rotor 63 is sucked into the turbo fan 75 through the opening 70 a formed in the frame 70 and blown out to the air supply duct 18 through the humidification duct 78. . The air humidified by the humidification rotor 63 in this way is guided to the air conditioning indoor unit 20 through the air supply duct 18.
- the part located in fan chamber S1 among the humidification rotors 63 becomes the moisture absorption area
- the portion located on the downstream side of the air flow from the heater 71 becomes the moisture release region 63b, and the other portion becomes the reheat region 63c.
- the reheat region 63 c is a portion where the outside air sucked from the suction port 72 first passes through the humidification rotor 63.
- the function of the humidification rotor 63 is switched in the order of the moisture absorption region 63a, the moisture release region 63b, and the reheat region 63c. Since the reheat region 63c is a portion that was the moisture release region 63b until immediately before, the temperature is high. For this reason, the outside air sucked from the suction port 72 is heated by the heat of the reheat region 63c by passing through the reheat region 63c. Further, the reheat area 63c is cooled by the passage of outside air, and then becomes the moisture absorption area 63a by the rotation of the humidification rotor 63.
- the humidification rotor is disposed along the horizontal plane, and the entire humidification rotor is located in the blower chamber, so that a part of the outdoor heat exchanger is blocked by the humidification unit, In the outdoor heat exchanger, it is difficult for outside air to pass through the portion blocked by the humidifying unit, and the performance of the outdoor heat exchanger may be deteriorated.
- the humidification rotor 63 is disposed along the vertical plane. Further, the moisture absorption area 63 a of the humidification rotor 63 is located in the blower room S 1 of the air conditioning room outside unit 30, and the moisture release area 63 b of the humidification rotor 63 is located in the machine room S 2 of the air conditioning room outside unit 30.

Since the dimensions can be shortened, the product size can be reduced.
- the upper end 63t of the humidification rotor 63 of the present embodiment is at a position lower than the upper end 33t of the outdoor heat exchanger 33. For this reason, compared with the case where the humidification rotor 63 is arrange
- the upper end 63t of the humidification rotor 63 is located at a position lower than the top plate 48, the outside air easily flows efficiently into the moisture absorption region 63a of the humidification rotor 63.
- the heater 71, the rotor drive motor 65, and the main body 51 of the electrical component box 50 are arranged in the machine room S ⁇ b> 2 of the air conditioning room outside unit 30.

For this reason, it becomes difficult for the heat from the heater 71 to be directly transmitted to the electrical component box 50, and the possibility that the electronic components and the control board in the main body 51 of the electrical component box 50 are deteriorated by heat can be reduced.
- the degree of freedom of the members constituting the electrical component box 50 is increased. That is, for example, when the electrical component box 50 is formed of a material such as a resin, it is necessary to select the material in consideration of heat resistance. However, in the present embodiment, heat from the heater 71 is not easily transmitted to the electrical component box 50. Therefore, the degree of freedom of material selection increases.
- the heater 71 and the electrical component box 50 are arranged on the same side with respect to the humidification rotor 63, it is necessary to secure a space to keep the electrical component box 50 away from the heater 71. Since the electric component box 50 can be separated from the heater 71 by disposing the heater 71 on the opposite side of the electric component box 50 with the 63 interposed therebetween, a separate for separating the electric component box 50 and the heater 71 from each other is provided. It is not necessary to secure the space, and the space in the air conditioning room outside unit 30 can be effectively used.

As a result, the durability of the rotor drive motor 65 can be ensured.
- the rotor drive motor is arranged in the blower chamber and is arranged between the humidification rotor and the outdoor fan, the outside air does not flow to the humidification rotor due to the ventilation resistance of the rotor drive motor, and the humidification rotor There is a possibility that the hygroscopic performance of the product may be lowered.
- the rotor drive motor 65 is disposed radially outside the outer periphery of the humidification rotor 63 so that the rotor drive motor 65 and the humidification rotor 63 do not overlap in front view.

The width dimension can be reduced. Thereby, the thickness reduction of the air-conditioning outdoor unit 30 can be realized.
- the machine room S2 is formed so that the width in the left-right direction becomes wider toward the front.
- the electrical component box 50 is disposed in front of the machine room S2.

Abstract
Description
寸法を大きくすることができる。
本発明の一実施形態に係る空調室外ユニット30を備える空気調和装置10は、図1に示すように、空調室外ユニット30の他に、空調室内ユニット20を備えており、空調室内ユニット20と空調室外ユニット30とが連絡配管12によって接続されて構成されている。この空気調和装置10は、冷房運転、暖房運転、除湿運転、加湿運転及び換気運転などの複数の運転モードを有しており、これらの運転モードを適宜組み合わせることもできる。
冷媒回路の動作は従来からあるものと変わらないが、図1に示す冷媒回路の動作について簡単に説明する。
(2-1)空調室内ユニット20の構成
空調室内ユニット20には、室内熱交換器21の他に、図1に示すように、モータで駆動される室内ファン22が室内熱交換器21の下流側に設けられている。室内ファン22としては、例えばクロスフローファンが採用される。室内ファン22が駆動されると、空調室内ユニット20上部の吸込口23から吸い込まれた室内空気が、室内熱交換器21を通過して空調室内ユニット20下部の吹出口24から吹き出される。
(2-2-1)空調室外ユニット30の構成の概要
空調室外ユニット30は、ケーシング40を備えている。そして、図1に示すように、ケーシング40の内部は、仕切板43によって送風機室S1と機械室S2とに分けられている。空調室外ユニット30では、送風機室S1から機械室S2に風が回り込まないように、送風機室S1と機械室S2とが仕切板43によって遮蔽されている。
図2は、空調室外ユニット30の正面図であり、空調室外ユニット30から電装品箱50、グリル及び前板46の一部が取り外された状態を示している。図3は、空調室外ユニット30の斜視図であり、電装品箱50の本体51、グリル及び天板48が取り外された空調室外ユニット30において、図2で取り外されている前板46の一部を仮想面とした状態を示している。図4は、空調室外ユニット30の平面図であり、空調室外ユニット30の天板48が取外された状態を示している。なお、図4に記載の矢印は、加湿ロータ63の吸湿領域63aを通る空気の流れを示している。
室外熱交換器33は、図3及び図4に示すように、上面視L型の形状を呈しており、ケーシング40の左側板45に正対する第1部分33aと、ケーシング40の背面を構成する保護金網に正対する第2部分33bとを有する。
室外ファン39は、室外熱交換器33の背面側(後方側)から室外熱交換器33を通して吸い込まれた外気を、空調室外ユニット30の正面側(前方側)に吹き出させるファンであって、本実施形態では、プロペラファンである。室外ファン39は、ファンモータ39aと、ファンモータ39aによって駆動されるプロペラ39bを有する。プロペラ39bは、その一部がベルマウス46aで囲まれた空間内に入るように配置されている。また、ファンモータ39aはプロペラ39bの背面側に取り付けられており、プロペラ39bの回転軸とファンモータ39aの駆動軸とが結合されている。さらに、ファンモータ39aは、ファンモータ台(図示せず)によって支持されている。ファンモータ台は、底板49及び室外熱交換器33の上端33tに固定された固定板(図示せず)に取り付けられている。
図5は、加湿ユニット60の分解図である。加湿ユニット60は、吸湿経路と放湿経路とを有しており、吸湿経路が空調室外ユニット30の送風機室S1に、放湿経路が空調室外ユニット30の機械室S2に位置するように配設されている。
加湿ロータ63は、1つの板状の吸放湿材である。なお、加湿ロータ63の形状は板状であればどのような形状であってもよい。本実施形態では、加湿ロータ63は、円盤状を呈するものとする。また、ここでいう1つの板状の吸放湿材には、単体の板状の吸放湿材が加湿ロータ63を構成しているものの他、同一形状又は異なる形状の吸放湿材が複数組み合わされて1つの板状の加湿ロータ63を構成しているものも含まれる。加湿ロータ63は、ゼオライト等の焼成によって形成されたハニカム構造のゼオライトロータである。加湿ロータ63は、円盤の中心を回転軸として回転するように取り付けられ、加湿ロータ63の周囲に設けられているギア64に伝達されるロータ駆動モータ65の動力によって回転駆動される。ロータ駆動モータ65は、その全体が機械室S2に配置されている。さらに、本実施形態では、ロータ駆動モータ65は、正面視において、加湿ロータ63と重ならないように、加湿ロータ63の外周よりも径方向外側に配置されている。
ヒータ71は、加湿ロータ63の放湿領域63bの側方に設けられている。ヒータ71は、筒状の筐体の中に電熱線(図示省略)が設けられた構造であり、吸入口72から吸入されて加湿ロータ63に送られる外気を電熱線で加熱する。加湿ロータ63では、加湿ロータ63のハニカム構造の開口を加熱された空気が通り抜けるときに、加湿ロータ63から放湿されることで、ターボファン75に吸い込まれる空気が加湿される。
ターボファン75は、空調室外ユニット30から空調室内ユニット20へと向かう空気流れを生成する。また、ターボファン75は、加湿ロータ63を挟んでヒータ71と対向ように配置されている。そして、電装品箱50は、ターボファン75及び加湿ロータ63を挟んでヒータ71とは反対側に配置されている。さらに、ターボファン75は、図2や図4に示すように、機械室S2に設置されている。
図6は、加湿ロータ63における空気流れを説明するための図である。図7は、加湿ロータ63の放湿領域63b、吸湿領域63a及び再熱領域63cを説明するための図である。なお、図7では、加湿ロータ63を正面から見た場合の放湿領域63b、吸湿領域63a及び再熱領域63cをそれぞれ示している。以下に、加湿運転時における空気の流れについて説明する。なお、空気調和装置10では、加湿運転は暖房運転と組み合わせて行われるものとする。このため、加湿運転時には、圧縮機31及び室外ファン39が駆動している。また、加湿運転時には、加湿ロータ63がロータ駆動モータ65の動力によって所定の回転速度で回転しており、ヒータ71及びターボファン75が駆動している。なお、加湿ロータ63は回転するので、吸湿領域63aでの吸湿によって加湿ロータ63に吸着された水分は加湿ロータ63の回転に伴って放湿領域63bに運ばれ、放湿領域63bでの放湿によって吸着されていた水分が脱着されることで放湿領域63bの周囲の空気が加湿される。また、本実施形態の加湿ロータ63は、正面から見て反計回りに回転しており、吸湿領域63aとして機能した部分が回転してヒータ支持部材74に対向する位置に来ると放湿領域63bとして機能する。
(4-1)
従来の空調室外ユニットには、加湿ロータが水平面に沿って配設されており、加湿ロータ全体が送風機室に位置していることで、室外熱交換器の一部が加湿ユニットで塞がれ、室外熱交換器において加湿ユニットで塞がれた部分を外気が通りにくくなり、室外熱交換器の性能が低下してしまうことがある。
本実施形態の加湿ロータ63の上端63tは、室外熱交換器33の上端33tよりも低い位置にある。このため、加湿ロータ63が、室外熱交換器33の上端33tよりも高い位置に配置されている場合と比較して、空調室外ユニット30の高さ寸法を抑えることができる。これにより、室外熱交換器33の能力を低減させずに製品サイズが大きくなるのを抑制することができている。
本実施形態では、ヒータ71、ロータ駆動モータ65、及び電装品箱50の本体51は、空調室外ユニット30の機械室S2に配置されている。このように電機部品が機械室S2にまとめて配置されていることで、配線の取り回しなど配線作業が簡易になる。これにより、空調室外ユニット30の組立性及びメンテナンス性(サービス性)を向上させることができている。
本実施形態では、加湿ロータ63と室外熱交換器33との間には隙間がある。このため、加湿ロータ63が室外熱交換器33に接触しないようにすることができる。これにより、加湿ロータ63の破損を防止することができている。特に、破損防止の観点から、本実施形態の加湿ロータ63のように回転する部材は室外熱交換器33に接触しないように構成することが好ましい。
本実施形態では、ヒータ71が、加湿ロータ63を挟んで電装品箱50とは反対側に配置されている。このように、空調室外ユニット30においてヒータ71が加湿ロータ63を挟んで電装品箱50とは反対側に配置されていることで、加湿ユニット60のヒータ71と電装品箱50とをできるだけ離隔することができる。このため、ヒータ71からの熱が電装品箱50に直接伝わりにくくなり、電装品箱50の本体51内の電子部品及び制御基板が熱により劣化するおそれを低減することができる。また、加湿ユニット60のヒータ71と電装品箱50とをできるだけ離隔することで、ヒータ71からの熱を電装品箱50に伝わり難くして、ヒートシンク52からの放熱が阻害されるおそれを低減することができる。
本実施形態では、ターボファン75が加湿ロータ63を挟んでヒータ71と対向ように配置されており、電装品箱50がターボファン75及び加湿ロータ63を挟んでヒータ71とは反対側に配置されている。このように、電装品箱50がターボファン75及び加湿ロータ63を挟んでヒータ71とは反対側に配置されていることで、ターボファン75の分だけさらにヒータ71と電装品箱50とを離隔させることができる。これにより、ヒータ71からの熱が電装品箱50に伝わるのをさらに抑制できる。
本実施形態では、ロータ駆動モータ65が機械室S2に配置されている。このため、室外ファン39の駆動によりロータ駆動モータ65が冷却されることがなく、これに起因するロータ駆動モータ65の異常を防ぐことができる。これによって、ロータ駆動モータ65の耐久性の確保を実現することができている。
本実施形態では、正面視において、電装品箱50の少なくとも一部が加湿ロータ63と重なるように配設されている。このため、例えば、加湿ロータ63と電装品箱50とが正面視において重ならないように左右に並んで配置されているよりも、ケーシング40の左右方向の寸法を小さくすることができる。
本実施形態では、加湿ロータ63及び電装品箱50それぞれが鉛直面に沿って配設されている。また、加湿ロータ63と電装品箱50とは、前後に並ぶように配置されている。このため、例えば、その長手方向が水平面に沿って延びるように電装品箱50が配設されている場合、すなわち電装品箱50が横置き配置されている場合よりも、ケーシング40の前後方向の幅寸法を小さくすることができる。これによって、空調室外ユニット30の薄型化を実現することができている。
本実施形態では、機械室S2が、前方に向かうにつれて左右方向の幅が広くなるように形成されている。また、電装品箱50は、機械室S2の内部前方に配置される。このため、電装品箱50が機械室S2の内部後方に配置されるよりも、電装品箱50の左右方向の寸法を大きくすることができる。これによって、電装品箱50の設計の自由度を向上させることができている。
(5-1)変形例A
上記実施形態の空調室外ユニット30では、後方から前方に向かって、加湿ユニット60、電装品箱50の順に配置されている。しかしながら、加湿ロータ63が仕切板43を跨ぐように配置されていれば、加湿ユニット60及び電装品箱50の位置関係はこれに限定されるものではなく、例えば、図8に示すように、後方から前方に向かって、電装品箱50、加湿ユニット60の順に配置されていてもよい。
上記実施形態の空調室外ユニット30では、室外ファン39が駆動することで、外気は、室外熱交換器33を通過した直後に加湿ロータ63の吸湿領域63aへと至っている。しかしながら、加湿ロータ63の吸湿領域63aを通る吸湿経路はこれに限定されるものではない。例えば、グリルの一部に閉鎖面を設け、室外ファン39によって生じる空気流れの一部が該閉鎖面に押し当たり、加湿ロータ63の吸湿領域63aへと至るようにしてもよい。
図9は、ガイド69の斜視図である。図10は、ガイド69が取り付けられた加湿ユニット60の斜視図である。図11は、ガイド69が取り付けられた加湿ユニット60を備える空調室外ユニット30の平面図であり、空調室外ユニット30の天板48が取外された状態を示している。なお、図11に記載の矢印は、加湿ロータ63の吸湿領域63aを通る空気の流れを示している。
