調湿ユニットHumidity control unit
　本開示は、調湿ユニット、特に、鉛直方向に沿う壁面にケーシングの背面を対向させて設置される調湿ユニットに関する。 The present disclosure relates to a humidity control unit, and in particular, to a humidity control unit that is installed with a back surface of a casing facing a wall surface along a vertical direction.
　従来より、室内の空気調和を行う空気調和機とは別体に構成され、空気調和機の室内機に加湿用空気を供給する加湿ユニットがある。このような加湿ユニットの中には、例えば特許文献１（特開２０１４－１２９９５０号公報）に記載されているように、室内機が取り付けられている壁に取り付けられるものもある。 Conventionally, there is a humidification unit that is configured separately from an air conditioner that performs indoor air conditioning and supplies humidification air to the indoor unit of the air conditioner. Some of such humidification units are attached to a wall to which an indoor unit is attached, as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2014-129950), for example.
　しかしながら、特許文献１に記載されている加湿ユニットは、壁に取り付けられる場合に壁に開けられた貫通穴に向けて外気吸込口から、ヒータ、吸着ロータ及びファンが配置されると加湿ユニットが厚くなって、加湿ユニットが壁から大きく突出してしまう。このように加湿ユニットが壁から大きく突出する場合には、ユーザがデザイン的に受け入れ難いものとなったり、加湿ユニットの据え付け強度を確保するために加湿ユニットを採用するためのコストが増加したりする。 However, when the humidifying unit described in Patent Document 1 is attached to the wall, the humidifying unit becomes thick when the heater, the suction rotor, and the fan are arranged from the outside air inlet toward the through hole opened in the wall. As a result, the humidification unit protrudes greatly from the wall. When the humidifying unit protrudes greatly from the wall in this way, it becomes difficult for the user to accept the design, or the cost for employing the humidifying unit to secure the installation strength of the humidifying unit increases. .

　＜第１実施形態＞
　以下、本開示の第１実施形態に係る調湿ユニットを図に基づいて説明する。第１実施形態では、空気調和装置に組み込まれた加湿ユニットを調湿ユニットの例に挙げて説明している。 <First Embodiment>
Hereinafter, the humidity control unit according to the first embodiment of the present disclosure will be described with reference to the drawings. In the first embodiment, the humidification unit incorporated in the air conditioner is described as an example of the humidity control unit.
　（１）全体構成
　図１には、実施形態に係る空気調和装置の全体構成が示されている。また、図２には、図１に示されている加湿ユニット３０の構成の概念が示されている。図１に示されている空気調和装置１は、室外機２と室内機４と冷媒連絡管５，６とを備え、空気調和装置１には加湿ユニット３０が取り付けられている。第１実施形態に係る空気調和装置１では、室外機２が室外ＯＤに設置され、室内機４が室内ＩＤに取り付けられ（図５参照）、室外機２と室内機４が冷媒連絡管５，６などで連絡されている。室外機２は、圧縮機２１と、四方弁２２と、室外熱交換器２３と、電動弁２４と、閉鎖弁２５と、閉鎖弁２６と室外ファン２７と、アキュムレータ２８とを備えている。また、室内機４は、室内熱交換器４２と室内ファン４１とを備えている。 (1) Whole structure The whole structure of the air conditioning apparatus which concerns on embodiment is shown by FIG. FIG. 2 shows the concept of the configuration of the humidifying unit 30 shown in FIG. An air conditioner 1 shown in FIG. 1 includes an outdoor unit 2, an indoor unit 4, and refrigerant communication pipes 5 and 6, and a humidifying unit 30 is attached to the air conditioner 1. In the air conditioner 1 according to the first embodiment, the outdoor unit 2 is installed in the outdoor OD, the indoor unit 4 is attached to the indoor ID (see FIG. 5), and the outdoor unit 2 and the indoor unit 4 are connected to the refrigerant communication pipe 5. 6 and so on. The outdoor unit 2 includes a compressor 21, a four-way valve 22, an outdoor heat exchanger 23, an electric valve 24, a closing valve 25, a closing valve 26, an outdoor fan 27, and an accumulator 28. The indoor unit 4 includes an indoor heat exchanger 42 and an indoor fan 41.
　室外機２と室内機４が冷媒連絡管５，６で接続されることにより、空気調和装置１の中には、蒸気圧縮式冷凍サイクルを行う冷媒回路１０が形成されている。冷媒回路１０には、圧縮機２１が組み込まれている。圧縮機２１は、低圧のガス冷媒を吸入し、吸入したガス冷媒を圧縮して、高温高圧のガス冷媒を吐出する。圧縮機２１は、例えば、インバータによる回転数制御を行うことのできる容量可変のインバータ圧縮機である。圧縮機２１の運転周波数が高くなるほど冷媒回路１０の冷媒循環量が多くなり、逆に運転周波数が低くなると冷媒回路１０の冷媒循環量が減少する。 By connecting the outdoor unit 2 and the indoor unit 4 with the refrigerant communication pipes 5 and 6, a refrigerant circuit 10 for performing a vapor compression refrigeration cycle is formed in the air conditioner 1. A compressor 21 is incorporated in the refrigerant circuit 10. The compressor 21 sucks in the low-pressure gas refrigerant, compresses the sucked-in gas refrigerant, and discharges the high-temperature and high-pressure gas refrigerant. The compressor 21 is, for example, a variable capacity inverter compressor that can perform rotation speed control by an inverter. As the operating frequency of the compressor 21 increases, the amount of refrigerant circulating in the refrigerant circuit 10 increases. Conversely, when the operating frequency decreases, the amount of refrigerant circulating in the refrigerant circuit 10 decreases.
　四方弁２２は、冷房運転と暖房運転の切換時に、冷媒の流れの方向を切り換えるための弁である。四方弁２２は、第１ポートが圧縮機２１の吐出側（吐出管２１ａ）に接続され、第２ポートに室外熱交換器２３が接続され、第３ポートにアキュムレータ２８が接続され、第４ポートに閉鎖弁２６を介して冷媒連絡管６が接続されている。この四方弁２２は、第１ポートと第２ポートの間を冷媒が流れるとともに第３ポートと第４ポートの間を冷媒が流れる破線で示された状態と、第１ポートと第４ポートの間を冷媒が流れるとともに第２ポートと第３ポートの間を冷媒が流れる実線で示された状態とを切り換えることができる。 The four-way valve 22 is a valve for switching the direction of the refrigerant flow when switching between the cooling operation and the heating operation. The four-way valve 22 has a first port connected to the discharge side (discharge pipe 21a) of the compressor 21, an outdoor heat exchanger 23 connected to the second port, an accumulator 28 connected to the third port, and a fourth port. The refrigerant communication pipe 6 is connected to the valve via a closing valve 26. This four-way valve 22 is in a state indicated by a broken line in which the refrigerant flows between the first port and the second port and the refrigerant flows between the third port and the fourth port, and between the first port and the fourth port. And the state indicated by the solid line through which the refrigerant flows between the second port and the third port.
　加湿ユニット３０の詳細な構成については後述するが、加湿ユニット３０は、再生用熱交換器３１を備えており、この再生用熱交換器３１が冷媒連絡管６に挿入されている。従って、暖房運転状態のときには、圧縮機２１から吐出される高温高圧のガス冷媒は、高温高圧のまま再生用熱交換器３１に送られる。この加湿ユニット３０は、再生用熱交換器３１により吸着ロータ３２に送り込む再生前空気を加熱することによって湿度の高い再生後空気を生成することができるので、主に、暖房運転状態のときに室内ＩＤを加湿することになる。 Although the detailed configuration of the humidification unit 30 will be described later, the humidification unit 30 includes a regeneration heat exchanger 31, and the regeneration heat exchanger 31 is inserted into the refrigerant communication tube 6. Therefore, in the heating operation state, the high-temperature and high-pressure gas refrigerant discharged from the compressor 21 is sent to the regeneration heat exchanger 31 while maintaining the high temperature and pressure. This humidifying unit 30 can generate post-regeneration air with high humidity by heating the pre-regeneration air that is sent to the adsorption rotor 32 by the regeneration heat exchanger 31. The ID will be humidified.
　四方弁２２の第２ポートと電動弁２４との間に配置されている室外熱交換器２３では、伝熱管（図示せず）を流れる冷媒と室外空気との間で熱交換が行われる。室外熱交換器２３は、冷房運転時には冷媒から熱を放出させる放熱器として機能し、暖房運転時には冷媒に熱を与える蒸発器として機能する。 In the outdoor heat exchanger 23 disposed between the second port of the four-way valve 22 and the motor-operated valve 24, heat is exchanged between the refrigerant flowing through the heat transfer pipe (not shown) and the outdoor air. The outdoor heat exchanger 23 functions as a radiator that releases heat from the refrigerant during the cooling operation, and functions as an evaporator that applies heat to the refrigerant during the heating operation.
　電動弁２４は、室外熱交換器２３と室内熱交換器４２との間に配置されている。電動弁２４は、室外熱交換器２３と室内熱交換器４２の間を流れる冷媒を膨張させて減圧する機能を有している膨張弁である。電動弁２４は、膨張弁開度を変更することができるように構成されており、膨張弁開度を小さくすることにより電動弁２４を通過する冷媒の流路抵抗を増加させることができ、膨張弁開度を大きくすることにより電動弁２４を通過する冷媒の流路抵抗を減少させることができる。このような電動弁２４は、暖房運転では、室内熱交換器４２から室外熱交換器２３に向かって流れる冷媒を膨張させて減圧し、冷房運転では、室外熱交換器２３から室内熱交換器４２に向かって流れる冷媒を膨張させて減圧する。 The electric valve 24 is disposed between the outdoor heat exchanger 23 and the indoor heat exchanger 42. The motor-operated valve 24 is an expansion valve having a function of expanding and depressurizing the refrigerant flowing between the outdoor heat exchanger 23 and the indoor heat exchanger 42. The motor-operated valve 24 is configured so that the opening degree of the expansion valve can be changed, and the flow path resistance of the refrigerant passing through the motor-operated valve 24 can be increased by reducing the opening degree of the expansion valve. By increasing the valve opening, the flow path resistance of the refrigerant passing through the motor-operated valve 24 can be reduced. Such an electric valve 24 expands and depressurizes the refrigerant flowing from the indoor heat exchanger 42 toward the outdoor heat exchanger 23 in the heating operation, and reduces the pressure in the cooling operation from the outdoor heat exchanger 23 to the indoor heat exchanger 42. The refrigerant flowing toward is expanded and decompressed.
　また、室外機２には、室外ファン２７が設けられており、室外ファン２７は、室外機２の内部に室外空気を吸入して、室外熱交換器２３に室外空気を供給した後に、室外機２の外部に熱交換後の空気を排出する。この室外ファン２７により、室外空気を冷却源又は加熱源として冷媒を冷却したり蒸発させたりする室外熱交換器２３の機能が促進される。室外ファン２７は、回転数を変更できる室外ファンモータ２７ａにより、駆動される。この室外ファン２７の回転数が変更されることにより、室外熱交換器２３を通過する室外空気の風量が変更される。 The outdoor unit 2 is provided with an outdoor fan 27. The outdoor fan 27 sucks outdoor air into the outdoor unit 2 and supplies the outdoor air to the outdoor heat exchanger 23. The air after heat exchange is discharged to the outside of 2. The outdoor fan 27 promotes the function of the outdoor heat exchanger 23 that cools or evaporates the refrigerant using outdoor air as a cooling source or a heating source. The outdoor fan 27 is driven by an outdoor fan motor 27a that can change the rotation speed. By changing the rotational speed of the outdoor fan 27, the air volume of the outdoor air passing through the outdoor heat exchanger 23 is changed.
　また、室内機４には、室内ファン４１が設けられており、この室内ファン４１は、室内機４の内部に室内空気を吸入して、室内熱交換器４２に室内空気を供給した後に、室内機４の外部に熱交換後の空気を排出する。この室内ファン４１により、室内空気を冷却源又は加熱源として冷媒を冷却したり蒸発させたりする室内熱交換器４２の機能が促進される。室内ファン４１は、回転数を変更できる室内ファンモータ４１ａにより、駆動される。 The indoor unit 4 is provided with an indoor fan 41. The indoor fan 41 sucks indoor air into the indoor unit 4 and supplies the indoor air to the indoor heat exchanger 42. The air after heat exchange is discharged to the outside of the machine 4. The indoor fan 41 promotes the function of the indoor heat exchanger 42 that cools or evaporates the refrigerant using indoor air as a cooling source or a heating source. The indoor fan 41 is driven by an indoor fan motor 41a that can change the rotation speed.
　なお、加湿ユニット３０の設置時には、閉鎖弁２５，２６が閉じられた状態で行われる。そして、加湿ユニット３０の設置が終わったときに、閉鎖弁２５，２６が開状態にされる。 In addition, when installing the humidification unit 30, it is performed in the state in which the closing valves 25 and 26 are closed. Then, when the installation of the humidifying unit 30 is finished, the closing valves 25 and 26 are opened.
　（２）基本動作
　加湿ユニット３０により室内ＩＤが加湿されるのは、主に、室内ＩＤが乾燥するときであり、加湿ユニット３０により室内ＩＤが加湿される時期に特に制限はない。例えば、日本では、冬場に室内が乾燥することが多いので、暖房運転時に加湿ユニット３０により加湿されることが多い。 (2) Basic operation The indoor ID is humidified by the humidifying unit 30 mainly when the indoor ID is dried, and there is no particular limitation on the timing when the indoor ID is humidified by the humidifying unit 30. For example, in Japan, the room is often dried in winter, and is often humidified by the humidifying unit 30 during heating operation.
　（２－１）暖房運転
　暖房運転時においては、冷媒回路１０は、四方弁２２が図１の実線で示される状態となっている。また、閉鎖弁２５，２６は開状態にされ、電動弁２４は冷媒を減圧するように開度調節される。 (2-1) Heating Operation During the heating operation, the refrigerant circuit 10 has the four-way valve 22 in the state indicated by the solid line in FIG. Moreover, the closing valves 25 and 26 are opened, and the opening degree of the electric valve 24 is adjusted so as to depressurize the refrigerant.
　このような暖房運転時の冷媒回路１０において圧縮機２１が駆動されると、低圧のガス冷媒は、吸入管２１ｂを通って圧縮機２１に吸入され、圧縮機２１において圧縮されて圧縮機２１の吐出側（吐出管２１ａ）から吐出される。圧縮機２１から吐出された高温高圧のガス冷媒は、四方弁２２の第１ポートと第４ポートと閉鎖弁２６と冷媒連絡管６を通って再生用熱交換器３１に送られる。再生用熱交換器３１で熱交換された冷媒は、冷媒連絡管６及び接続管７１を通って室内熱交換器４２に入る。高温高圧のガス冷媒は、室内熱交換器４２において室内ファン４１から吹き出される室内空気との熱交換により放熱する。放熱後の高圧の冷媒は、接続管７２、冷媒連絡管５及び閉鎖弁２５を通って電動弁２４に送られる。電動弁２４を通過した冷媒は、電動弁２４において減圧されて低圧の気液二相状態の冷媒となる。電動弁２４を出た低圧の気液二相状態の冷媒は室外熱交換器２３に入る。室外熱交換器２３において、低圧の気液二相状態の冷媒は、室外空気との熱交換により蒸発する。室外熱交換器２３から出た低圧のガス冷媒は、四方弁２２の第２ポートと第３ポートとアキュムレータ２８を通って圧縮機２１の吸入側（吸入管２１ｂ）に再び送られる。 When the compressor 21 is driven in the refrigerant circuit 10 during such heating operation, the low-pressure gas refrigerant is sucked into the compressor 21 through the suction pipe 21b, and is compressed by the compressor 21 so that the compressor 21 It discharges from the discharge side (discharge pipe 21a). The high-temperature and high-pressure gas refrigerant discharged from the compressor 21 is sent to the regeneration heat exchanger 31 through the first port, the fourth port, the closing valve 26 and the refrigerant communication pipe 6 of the four-way valve 22. The refrigerant heat-exchanged in the regeneration heat exchanger 31 enters the indoor heat exchanger 42 through the refrigerant communication pipe 6 and the connection pipe 71. The high-temperature and high-pressure gas refrigerant radiates heat by exchanging heat with indoor air blown out from the indoor fan 41 in the indoor heat exchanger 42. The high-pressure refrigerant after heat radiation is sent to the motor-operated valve 24 through the connection pipe 72, the refrigerant communication pipe 5, and the closing valve 25. The refrigerant that has passed through the motor-operated valve 24 is decompressed by the motor-operated valve 24 and becomes a low-pressure gas-liquid two-phase refrigerant. The low-pressure gas-liquid two-phase refrigerant exiting the motor-operated valve 24 enters the outdoor heat exchanger 23. In the outdoor heat exchanger 23, the low-pressure gas-liquid two-phase refrigerant evaporates by heat exchange with outdoor air. The low-pressure gas refrigerant discharged from the outdoor heat exchanger 23 passes through the second port and third port of the four-way valve 22 and the accumulator 28 and is sent again to the suction side (suction pipe 21b) of the compressor 21.
　（２－２）冷房運転
　冷房運転時においては、冷媒回路１０は、四方弁２２が図１の破線で示される状態となっている。また、閉鎖弁２５，２６は開状態にされ、電動弁２４は冷媒を減圧するように開度調節される。 (2-2) Cooling Operation During the cooling operation, the refrigerant circuit 10 has the four-way valve 22 in the state indicated by the broken line in FIG. Moreover, the closing valves 25 and 26 are opened, and the opening degree of the electric valve 24 is adjusted so as to depressurize the refrigerant.
　このような冷房運転時の冷媒回路１０において圧縮機２１が駆動されると、低圧のガス冷媒は、吸入管２１ｂを通って圧縮機２１に吸入され、圧縮機２１において圧縮されて圧縮機２１の吐出側（吐出管２１ａ）から吐出される。圧縮機２１から吐出された高温高圧のガス冷媒は、四方弁２２の第１ポートと第２ポートを通って室外熱交換器２３に送られる。高温高圧のガス冷媒は、室外熱交換器２３において室外空気との熱交換により放熱する。放熱後の高圧の冷媒は、電動弁２４に送られる。電動弁２４を通過した冷媒は、電動弁２４において減圧されて低圧の気液二相状態の冷媒となる。この低圧の気液二相状態の冷媒は、閉鎖弁２５、冷媒連絡管５及び接続管７２を通って室内熱交換器４２に送られる。室内熱交換器４２において、低圧の気液二相状態の冷媒は、室内ファン４１から吹き出される室内空気との熱交換により蒸発して低圧のガス冷媒となる。室内熱交換器４２から出た低圧のガス冷媒は、接続管７１、再生用熱交換器３１が挿入された冷媒連絡管６、閉鎖弁２６、四方弁２２（第４ポートから第３ポート）、及びアキュムレータ２８を通って圧縮機２１の吸入側（吸入管２１ｂ）に再び送られる。 When the compressor 21 is driven in the refrigerant circuit 10 during such cooling operation, the low-pressure gas refrigerant is sucked into the compressor 21 through the suction pipe 21b, and is compressed by the compressor 21 so that the compressor 21 It discharges from the discharge side (discharge pipe 21a). The high-temperature and high-pressure gas refrigerant discharged from the compressor 21 is sent to the outdoor heat exchanger 23 through the first port and the second port of the four-way valve 22. The high-temperature and high-pressure gas refrigerant radiates heat in the outdoor heat exchanger 23 by heat exchange with outdoor air. The high-pressure refrigerant after heat radiation is sent to the motor operated valve 24. The refrigerant that has passed through the motor-operated valve 24 is decompressed by the motor-operated valve 24 and becomes a low-pressure gas-liquid two-phase refrigerant. The low-pressure gas-liquid two-phase refrigerant is sent to the indoor heat exchanger 42 through the closing valve 25, the refrigerant communication pipe 5 and the connection pipe 72. In the indoor heat exchanger 42, the low-pressure gas-liquid two-phase refrigerant evaporates by heat exchange with the indoor air blown out from the indoor fan 41 to become a low-pressure gas refrigerant. The low-pressure gas refrigerant discharged from the indoor heat exchanger 42 includes a connection pipe 71, a refrigerant communication pipe 6 into which the regeneration heat exchanger 31 is inserted, a closing valve 26, a four-way valve 22 (from the fourth port to the third port), And is again sent to the suction side (suction pipe 21b) of the compressor 21 through the accumulator 28.
　（３）詳細構成
　（３－１）加湿ユニット３０
　図３には、加湿ユニット３０の正面から見た外観が示されている。図３に示されているＺ軸方向が鉛直方向であり、Ｘ軸方向が左右方向である。図３に示されている加湿ユニット３０は、壁面ＷＳに取り付けられている。壁面ＷＳは、ＸＺ平面に対して平行に広がっている。 (3) Detailed configuration (3-1) Humidification unit 30
FIG. 3 shows the appearance of the humidifying unit 30 as viewed from the front. The Z-axis direction shown in FIG. 3 is the vertical direction, and the X-axis direction is the left-right direction. The humidifying unit 30 shown in FIG. 3 is attached to the wall surface WS. The wall surface WS extends parallel to the XZ plane.
　図１に示されているように、加湿ユニット３０は、再生用熱交換器３１と吸着ロータ３２とロータ用モータ３３と吸着用ファン３４と再生用ファン３５と加湿ホース３６とを備えている。再生用熱交換器３１と吸着ロータ３２とロータ用モータ３３と吸着用ファン３４と再生用ファン３５は、図３に示されているケーシング５０の内部に収納されている。 As shown in FIG. 1, the humidification unit 30 includes a regeneration heat exchanger 31, an adsorption rotor 32, a rotor motor 33, an adsorption fan 34, a regeneration fan 35, and a humidification hose 36. The regeneration heat exchanger 31, the adsorption rotor 32, the rotor motor 33, the adsorption fan 34, and the regeneration fan 35 are accommodated in the casing 50 shown in FIG.
　加湿ユニット３０においては、図２に示されているように、吸着前空気が吸着前空気取入口５２から取り入れられて吸着ロータ３２のうちの吸着領域に送られる。吸着ロータ３２のうちの吸着領域で水分を奪われた吸着後空気は、吸着用ファン吹出口５６から吹出される。これら吸着前空気及び吸着後空気の気流は吸着用ファン３４により発生される。また、再生前空気は、再生前空気取入口５４から取り入れられ、再生用熱交換器３１を通過するときに加熱されて吸着ロータ３２のうちの再生領域に送られる。吸着ロータ３２のうちの再生領域で水分を与えられた再生後空気は、再生後空気用ダクト３５ｅ及び加湿ホース３６を通って室内機４の内部に吹出される。これら再生前空気及び再生後空気の気流は再生用ファン３５により発生される。 In the humidification unit 30, as shown in FIG. 2, pre-adsorption air is taken in from the pre-adsorption air intake 52 and sent to the adsorption region of the adsorption rotor 32. The post-adsorption air that has been deprived of moisture in the adsorption region of the adsorption rotor 32 is blown out from the adsorption fan outlet 56. The pre-adsorption air and post-adsorption air streams are generated by the adsorption fan 34. The pre-regeneration air is taken in from the pre-regeneration air intake 54, heated when passing through the regeneration heat exchanger 31, and sent to the regeneration region of the adsorption rotor 32. The regenerated air given moisture in the regeneration region of the adsorption rotor 32 is blown out into the indoor unit 4 through the regenerated air duct 35e and the humidifying hose 36. The airflow of the air before regeneration and the air after regeneration is generated by the regeneration fan 35.
　（３－１－１）ケーシング５０
　図４には、図３のＩ－Ｉ線に沿った加湿ユニット３０の断面が示されている。図４において、Ｙ軸方向が前後方向である。なお、図４などの断面図において、図を見やすくするために一部斜線などのハッチングを省略している。図３及び図４に示されているように、加湿ユニット３０のケーシング５０の形状は、直方体を基礎として設計されている。そのため、ケーシング５０においては、正面５０ａ、背面５０ｂ、上側面５０ｃ、下側面５０ｄ、右側面５０ｅ、左側面５０ｆが外観の大部分を占める。正面５０ａは、背面５０ｂに対向する面である。上側面５０ｃ、下側面５０ｄ、右側面５０ｅ及び左側面５０ｆは、正面５０ａと背面５０ｂとの間にある側面である。なお、右側面５０ｅと背面５０ｂの間には、斜めに傾斜した右傾斜面５０ｇがあり、左側面５０ｆと背面５０ｂの間には、斜めに傾斜した左傾斜面５０ｈがある（図６参照）。 (3-1-1) Casing 50
FIG. 4 shows a cross section of the humidifying unit 30 along the line II in FIG. In FIG. 4, the Y-axis direction is the front-rear direction. Note that in cross-sectional views such as FIG. 4, hatching such as oblique lines is partially omitted for easy understanding of the drawing. As shown in FIGS. 3 and 4, the shape of the casing 50 of the humidifying unit 30 is designed based on a rectangular parallelepiped. Therefore, in the casing 50, the front 50a, the back 50b, the upper side 50c, the lower side 50d, the right side 50e, and the left side 50f occupy most of the appearance. The front surface 50a is a surface facing the back surface 50b. The upper side surface 50c, the lower side surface 50d, the right side surface 50e, and the left side surface 50f are side surfaces located between the front surface 50a and the back surface 50b. In addition, there is a right inclined surface 50g inclined obliquely between the right side surface 50e and the back surface 50b, and there is a left inclined surface 50h inclined obliquely between the left side surface 50f and the back surface 50b (see FIG. 6).
　図５に示されている加湿ユニット３０は、鉛直方向に沿う壁面ＷＳに背面５０ｂが接触するように取り付けられている。しかし、ケーシング５０は、壁面ＷＳに接触するように取り付けられなくてもよく、ケーシング５０の背面５０ｂが壁面ＷＳに対向するように取り付けられていればよい。例えば、壁面ＷＳに平行に配置された枠体にケーシング５０が取り付けられてもよい。図５に示されている壁１００には、貫通孔１０１が形成されている。この貫通孔１０１の中を、冷媒連絡管５,６及び加湿ホース３６が通っている。 The humidifying unit 30 shown in FIG. 5 is attached so that the back surface 50b contacts the wall surface WS along the vertical direction. However, the casing 50 may not be attached so as to be in contact with the wall surface WS, and may be attached so that the back surface 50b of the casing 50 faces the wall surface WS. For example, the casing 50 may be attached to a frame disposed in parallel with the wall surface WS. A through hole 101 is formed in the wall 100 shown in FIG. The refrigerant communication pipes 5 and 6 and the humidifying hose 36 pass through the through hole 101.
　ケーシング５０は、図４に示されている、背面５０ｂに対する垂直方向（Ｙ軸方向）の寸法Ｍ１（正面５０ａと背面５０ｂの間の距離）が、背面５０ｂに平行な方向（ＸＺ平面に平行な方向）の寸法よりも小さい。背面５０ｂに平行な方向で正面５０ａの寸法が最も小さいのは、右側面５０ｅと左側面５０ｆの間の距離（Ｘ軸方向の寸法Ｍ２（図３参照））である。図３と図４とを比較して分かるように、正面５０ａと背面５０ｂの間の距離（寸法Ｍ１）は、右側面５０ｅと左側面５０ｆの間の距離（寸法Ｍ２）より小さい。つまり、ケーシング５０は、薄型化されている。 In the casing 50, a dimension M1 (distance between the front surface 50a and the back surface 50b) perpendicular to the back surface 50b (a distance between the front surface 50a and the back surface 50b) shown in FIG. 4 is parallel to the back surface 50b (parallel to the XZ plane). Direction) dimension. The smallest dimension of the front surface 50a in the direction parallel to the back surface 50b is the distance between the right side surface 50e and the left side surface 50f (dimension M2 in the X-axis direction (see FIG. 3)). As can be seen by comparing FIG. 3 and FIG. 4, the distance (dimension M1) between the front surface 50a and the rear surface 50b is smaller than the distance (dimension M2) between the right side surface 50e and the left side surface 50f. That is, the casing 50 is thinned.
　図３及び図４に示されているケーシング５０では、ケーシング５０の最も長い辺がＺ軸方向に沿うように配置されて、上から順に（上側面５０ｃに近い方から順に）、再生用ファン３５、吸着ロータ３２、吸着用ファン３４が並んでいる。 In the casing 50 shown in FIGS. 3 and 4, the longest side of the casing 50 is arranged along the Z-axis direction, and in order from the top (from the side closer to the upper side surface 50 c), the regeneration fan 35. The suction rotor 32 and the suction fan 34 are arranged side by side.
　ケーシング５０の正面５０ａには、図３に示されているように、グリッド５１が取り付けられている。図６には、加湿ユニット３０の正面５０ａからグリッド５１が取り外された外観が示されている。図６に示されているケーシング５０は、左斜め下方から見たものである。ケーシング５０の正面５０ａには、正面５０ａの中央部より少し下の箇所に半円形状の吸着前空気取入口５２が形成されている。吸着前空気取入口５２の長手方向は、Ｘ軸方向に平行である（図８参照）。吸着前空気取入口５２からは、露出した吸着ロータ３２が見えている。 A grid 51 is attached to the front surface 50a of the casing 50 as shown in FIG. FIG. 6 shows an appearance in which the grid 51 is removed from the front surface 50 a of the humidifying unit 30. The casing 50 shown in FIG. 6 is viewed from the diagonally lower left. A semicircular pre-adsorption air intake 52 is formed on the front surface 50a of the casing 50 at a position slightly below the central portion of the front surface 50a. The longitudinal direction of the pre-adsorption air intake 52 is parallel to the X-axis direction (see FIG. 8). The exposed adsorption rotor 32 is visible from the pre-adsorption air intake 52.
　ケーシング５０の左側面５０ｆには、配管接続部カバー５３が取り付けられている。図７には、配管接続部カバー５３が取り外された状態の加湿ユニット３０の外観の一部が拡大されて示されている。配管接続部カバー５３は、配管接続部３１ａ，３１ｂを覆っている。配管接続部３１ａは、閉鎖弁２６に繋がっている冷媒連絡管６に接続される。配管接続部３１ｂは、室内機４の室内熱交換器４２に繋がっている冷媒連絡管６に接続される。ケーシング５０の左側面５０ｆには、再生前空気取入口５４が形成されており、また加湿ホース３６をケーシング５０の内部から外部に取り出すための開口部５５が形成されている。再生前空気取入口５４は、図示を省略しているが、右側面５０ｅにも形成されている。ケーシング５０の下側面５０ｄには、吸着用ファン吹出口５６が形成されている。 A pipe connection portion cover 53 is attached to the left side surface 50 f of the casing 50. FIG. 7 shows an enlarged part of the external appearance of the humidifying unit 30 in a state in which the pipe connection portion cover 53 is removed. The pipe connection part cover 53 covers the pipe connection parts 31a and 31b. The pipe connection part 31 a is connected to the refrigerant communication pipe 6 connected to the closing valve 26. The pipe connection part 31 b is connected to the refrigerant communication pipe 6 connected to the indoor heat exchanger 42 of the indoor unit 4. A pre-regeneration air intake 54 is formed on the left side surface 50 f of the casing 50, and an opening 55 for taking out the humidifying hose 36 from the inside of the casing 50 to the outside is formed. Although not shown, the pre-regeneration air intake 54 is also formed on the right side surface 50e. An adsorption fan blowout port 56 is formed on the lower side surface 50 d of the casing 50.
　（３－１－２）吸着ロータユニット３９
　吸着ロータユニット３９は、再生用熱交換器３１と吸着ロータ３２とロータ用モータ３３とを含んで構成されている。吸着ロータ３２は、円盤状の部材である。吸着ロータ３２の円形の表面３２ａから円形の裏面３２ｂまでのロータ本体３２ｃには貫通した穴（図示せず）が多数形成さており、表面３２ａから裏面３２ｂまで吸着ロータ３２の中を空気が通り抜けるように構成されている。この吸着ロータ３２には、高分子の吸着材が含まれている。吸着材は、吸着ロータ３２を通り抜ける空気から水分を吸着する機能を有しており、常温よりも高い温度に加熱された空気が吸着ロータ３２の中を通過すると水分をその加熱された空気中に脱離する機能を有している。吸着ロータ３２が配置されている円盤状の領域の中で、吸着前空気取入口５２から取り入れられた空気が吸着用ファン吹出口５６から吹出されるまでに通過するのが吸着領域であり、再生前空気取入口５４から取り入れられた空気が加湿ホース３６を通って室内機４に送られるまでに通過するのが再生領域である。これら吸着領域と再生領域は重ならないように配置されている。第１実施形態の加湿ユニット３０では、吸着領域は概ね円盤状の領域の下半分を占め、再生領域は概ね円盤状の領域の上半分を占める。なお、吸着領域と再生領域の占有割合は適宜設計することができ、例えば、再生領域を扇形にして残りを吸着領域とするように構成してもよい。 (3-1-2) Adsorption rotor unit 39
The adsorption rotor unit 39 includes a regeneration heat exchanger 31, an adsorption rotor 32, and a rotor motor 33. The suction rotor 32 is a disk-shaped member. A large number of through holes (not shown) are formed in the rotor body 32c from the circular surface 32a to the circular back surface 32b of the adsorption rotor 32 so that air can pass through the adsorption rotor 32 from the surface 32a to the back surface 32b. It is configured. The adsorption rotor 32 contains a polymeric adsorbent. The adsorbent has a function of adsorbing moisture from the air passing through the adsorption rotor 32, and when air heated to a temperature higher than normal temperature passes through the adsorption rotor 32, moisture is absorbed into the heated air. It has a function to detach. In the disk-shaped region where the suction rotor 32 is arranged, the suction region passes through the air taken in from the pre-adsorption air intake 52 until it is blown out from the suction fan blow-out port 56. In the regeneration region, the air taken in from the front air inlet 54 passes through the humidifying hose 36 and is sent to the indoor unit 4. These adsorption area and regeneration area are arranged so as not to overlap. In the humidifying unit 30 of the first embodiment, the adsorption area occupies the lower half of the generally disk-shaped area, and the regeneration area occupies the upper half of the generally disk-shaped area. Note that the occupation ratio of the adsorption area and the reproduction area can be designed as appropriate. For example, the reproduction area may be a sector and the rest may be an adsorption area.
　吸着ロータユニット３９は、吸着ロータ３２が第１回転軸３２ｄの周りで回転するように吸着ロータ３２を支持している。第１回転軸３２ｄは、背面５０ｂに対する垂直方向（Ｙ軸方向）に延びている。吸着ロータ３２は、例えば１時間に３０回転する。吸着ロータ３２は、第１回転軸３２ｄの周りを１回転すると、吸着領域と再生領域を通過して、水分の吸着と水分の脱離を行う。そのために、再生用熱交換器３１を通過して加熱された再生前空気が全て吸着ロータ３２を通過できるように、吸着ロータユニット３９は、再生用熱交換器３１を保持するとともに再生用熱交換器３１を通過した後さらに再生領域を通過する空気の経路を形成している。 The suction rotor unit 39 supports the suction rotor 32 so that the suction rotor 32 rotates around the first rotation shaft 32d. The first rotation shaft 32d extends in a direction perpendicular to the back surface 50b (Y-axis direction). For example, the suction rotor 32 rotates 30 times per hour. When the adsorption rotor 32 makes one rotation around the first rotation shaft 32d, the adsorption rotor 32 passes through the adsorption region and the regeneration region, and adsorbs moisture and desorbs moisture. For this purpose, the adsorption rotor unit 39 holds the regeneration heat exchanger 31 and reproduces the heat for regeneration so that all the pre-regeneration air heated through the regeneration heat exchanger 31 can pass through the adsorption rotor 32. An air path that passes through the regeneration region after passing through the vessel 31 is formed.
　（３－１－３）吸着用ファン３４
　ここでは、吸着用ファン３４にシロッコファンが用いられている例を示しているが、吸着用ファン３４に用いることができるファンはシロッコファンに限られるものではない。ただし、吸着用ファン３４には、占有体積と送風量の条件を満たし易い遠心ファンが用いられることが好ましい。吸着用ファン３４は、第２回転軸３４ｂの周りで回転する吸着用ファンロータ３４ａと、吸着用モータ３４ｃと、吸着用ファンケース３４ｄと、吸着後空気用ダクト３４ｅとを備えている。第２回転軸３４ｂは、背面５０ｂに対する垂直方向に延びている。吸着用モータ３４ｃは、吸着用ファンロータ３４ａを回転させる。吸着用ファン３４は、吸着用ファンロータ３４ａによって、吸着前空気を吸着前空気取入口５２から吸着ロータ３２に導く。そして、吸着前空気が、吸着用ファンロータ３４ａにより送られて吸着ロータ３２の吸着領域を通過する。吸着ロータ３２を通過することで吸着ロータ３２に水分を奪われた空気が吸着後空気になる。このとき吸着ロータ３２を通過する空気は、吸着ロータ３２の第１回転軸３２ｄと平行に吸着ロータ３２を通過する。このように第１回転軸３２ｄと平行に吸着ロータ３２を空気が通過すると、第１回転軸３２ｄに対して傾いて例えば３０度よりも傾いて空気が通過する場合に比べて吸着ロータ３２を通過する空気の受ける抵抗が小さくなる。 (3-1-3) Suction fan 34
Here, an example in which a sirocco fan is used for the suction fan 34 is shown, but a fan that can be used for the suction fan 34 is not limited to a sirocco fan. However, the suction fan 34 is preferably a centrifugal fan that easily satisfies the conditions of the occupied volume and the air volume. The suction fan 34 includes a suction fan rotor 34a that rotates around the second rotation shaft 34b, a suction motor 34c, a suction fan case 34d, and a post-adsorption air duct 34e. The second rotating shaft 34b extends in a direction perpendicular to the back surface 50b. The suction motor 34c rotates the suction fan rotor 34a. The adsorption fan 34 guides pre-adsorption air from the pre-adsorption air intake 52 to the adsorption rotor 32 by the adsorption fan rotor 34a. Then, the pre-adsorption air is sent by the adsorption fan rotor 34 a and passes through the adsorption region of the adsorption rotor 32. Air that has been deprived of moisture by the adsorption rotor 32 by passing through the adsorption rotor 32 becomes air after adsorption. At this time, the air passing through the suction rotor 32 passes through the suction rotor 32 in parallel with the first rotation shaft 32 d of the suction rotor 32. When air passes through the suction rotor 32 in parallel with the first rotation shaft 32d in this way, the air passes through the suction rotor 32 as compared with the case where the air passes through the first rotation shaft 32d with an inclination of, for example, more than 30 degrees. The resistance to air is reduced.
　吸着ロータ３２の裏面３２ｂの側には、吸着後空気用ダクト３４ｅが配置されている。吸着後空気用ダクト３４ｅは、正面視において、吸着ロータ３２と吸着領域とが重なる部分よりも大きく、また吸着用ファン３４のベルマウス３４ｇの吸込円孔３４ｆよりも大きい。そして、吸着後空気用ダクト３４ｅは、正面視において、吸着ロータ３２と吸着領域とが重なる部分及びベルマウス３４ｇの吸込円孔３４ｆを覆うように配置されている。吸着後空気用ダクト３４ｅから吸着用ファン３４のベルマウス３４ｇの吸込円孔３４ｆを通って吸着用ファン３４に吸い込まれた吸着後空気は、吸着用ファン吹出口５６から吹出される。 A post-adsorption air duct 34e is disposed on the back surface 32b side of the adsorption rotor 32. The post-adsorption air duct 34e is larger than the portion where the adsorption rotor 32 and the adsorption area overlap in front view, and larger than the suction circular hole 34f of the bell mouth 34g of the adsorption fan 34. Further, the post-adsorption air duct 34e is arranged so as to cover the portion where the adsorption rotor 32 and the adsorption region overlap and the suction circular hole 34f of the bell mouth 34g in a front view. The adsorbed air sucked into the adsorbing fan 34 from the adsorbed air duct 34e through the suction circular hole 34f of the bell mouth 34g of the adsorbing fan 34 is blown out from the adsorbing fan outlet 56.
　（３－１－４）再生用ファン３５
　ここでは、再生用ファン３５にターボファンが用いられている例を示しているが、再生用ファン３５に用いることができるファンはターボファンに限られるものではない。ただし、再生用ファン３５には、占有体積と送風量の条件を満たし易い遠心ファンが用いられることが好ましい。再生用ファン３５は、第３回転軸３５ｂの周りで回転する再生用ファンロータ３５ａと、再生用モータ３５ｃと、再生用ファンケース３５ｄと、再生後空気用ダクト３５ｅとを備えている。第３回転軸３５ｂは、背面５０ｂに対する垂直方向に延びている。再生用モータ３５ｃは、再生用ファンロータ３５ａを回転させる。再生用ファン３５は、再生用ファンロータ３５ａによって、再生前空気を再生前空気取入口５４から吸着ロータ３２に導く。そして、再生前空気が、再生用ファンロータ３５ａにより送られて吸着ロータ３２の再生領域を通過する。吸着ロータ３２を通過することで吸着ロータ３２に水分を与えられた空気が再生後空気になる。再生前空気は、吸着ロータ３２の裏面３２ｂに達する前に、再生用熱交換器３１によって加熱されている。このとき吸着ロータ３２を通過する空気は、吸着ロータ３２の第１回転軸３２ｄと平行に吸着ロータ３２を通過する。このように第１回転軸３２ｄと平行に吸着ロータ３２を空気が通過すると、第１回転軸３２ｄに対して傾いて例えば３０度よりも傾いて空気が通過する場合に比べて吸着ロータ３２を通過する空気の受ける抵抗が小さくなる。 (3-1-4) Regeneration fan 35
Here, an example in which a turbo fan is used as the reproduction fan 35 is shown, but a fan that can be used as the reproduction fan 35 is not limited to a turbo fan. However, it is preferable to use a centrifugal fan that can easily satisfy the conditions of the occupied volume and the blowing amount as the regeneration fan 35. The regeneration fan 35 includes a regeneration fan rotor 35a that rotates around the third rotation shaft 35b, a regeneration motor 35c, a regeneration fan case 35d, and a post-regeneration air duct 35e. The third rotation shaft 35b extends in a direction perpendicular to the back surface 50b. The reproduction motor 35c rotates the reproduction fan rotor 35a. The regeneration fan 35 guides the pre-regeneration air from the pre-regeneration air intake 54 to the adsorption rotor 32 by the regeneration fan rotor 35a. Then, the pre-regeneration air is sent by the regeneration fan rotor 35 a and passes through the regeneration region of the adsorption rotor 32. The air given moisture to the adsorption rotor 32 by passing through the adsorption rotor 32 becomes air after regeneration. The pre-regeneration air is heated by the regeneration heat exchanger 31 before reaching the back surface 32 b of the adsorption rotor 32. At this time, the air passing through the suction rotor 32 passes through the suction rotor 32 in parallel with the first rotation shaft 32 d of the suction rotor 32. When air passes through the suction rotor 32 in parallel with the first rotation shaft 32d in this way, the air passes through the suction rotor 32 as compared with the case where the air passes through the first rotation shaft 32d with an inclination of, for example, more than 30 degrees. The resistance to air is reduced.
　吸着ロータ３２の表面３２ａの側には、再生後空気用ダクト３５ｅが配置されている。再生後空気用ダクト３５ｅは、正面視において、吸着ロータ３２と再生領域とが重なる部分よりも大きく、また再生用ファン３５の吸込口３５ｆよりも大きい。そして、再生後空気用ダクト３５ｅは、正面視において、吸着ロータ３２と再生領域とが重なる部分及び吸込口３５ｆを覆うように配置されている。再生後空気用ダクト３５ｅから再生用ファン３５の吸込口３５ｆを通って再生用ファン３５に吸い込まれた再生後空気は、加湿ホース３６を通って吹出される。 A post-regeneration air duct 35e is disposed on the surface 32a side of the adsorption rotor 32. The post-regeneration air duct 35e is larger than the portion where the suction rotor 32 and the regeneration region overlap in front view, and larger than the suction port 35f of the regeneration fan 35. The post-regeneration air duct 35e is disposed so as to cover the portion where the suction rotor 32 and the regeneration region overlap and the suction port 35f when viewed from the front. The post-regeneration air sucked into the regeneration fan 35 from the post-regeneration air duct 35e through the suction port 35f of the regeneration fan 35 is blown out through the humidification hose 36.
　（３－１－５）吸着ロータ３２と吸着用ファン３４と再生用ファン３５の位置関係
　吸着ロータ３２と吸着用ファン３４の吸着用ファンロータ３４ａと再生用ファン３５の再生用ファンロータ３５ａは、背面５０ｂに沿って一方向（Ｚ軸方向）に並べて配列されている。さらに詳細には、図８に示されているように、吸着ロータ３２の第１回転軸３２ｄと吸着用ファンロータ３４ａの第２回転軸３４ｂと再生用ファンロータ３５ａの第３回転軸３５ｂとが、Ｚ軸方向に延びる一つの直線Ｌ１と直交するように並んでいる。図８には、正面視における吸着ロータ３２と吸着用ファン３４と再生用ファン３５の配置が破線で示されている。吸着ロータ３２と吸着用ファンロータ３４ａと再生用ファンロータ３５ａの配列方向視、つまり直線Ｌ１に沿って下側面５０ｄから上側面５０ｃの方を見ると、図９に示されているように、吸着ロータ３２の一部と吸着用ファンロータ３４ａの一部が重なり、それらの重なった部分と再生用ファンロータ３５ａが重なっている。そのため、吸着ロータ３２と吸着用ファン３４と再生用ファン３５を背面５０ｂに沿って平らに並べて配置することができ、加湿ユニット３０が薄型化できている。 (3-1-5) Positional relationship between the suction rotor 32, the suction fan 34, and the regeneration fan 35 The suction fan rotor 34a of the suction rotor 32, the suction fan 34, and the regeneration fan rotor 35a of the regeneration fan 35 are: They are arranged in one direction (Z-axis direction) along the back surface 50b. More specifically, as shown in FIG. 8, the first rotation shaft 32d of the suction rotor 32, the second rotation shaft 34b of the suction fan rotor 34a, and the third rotation shaft 35b of the regeneration fan rotor 35a are provided. Are arranged so as to be orthogonal to one straight line L1 extending in the Z-axis direction. In FIG. 8, the arrangement of the suction rotor 32, the suction fan 34, and the regeneration fan 35 in the front view is indicated by broken lines. When the suction rotor 32, the suction fan rotor 34a, and the regeneration fan rotor 35a are viewed in the arrangement direction, that is, when viewed from the lower side surface 50d to the upper side surface 50c along the straight line L1, as shown in FIG. A portion of the rotor 32 and a portion of the suction fan rotor 34a overlap, and the overlapping portion and the regeneration fan rotor 35a overlap. Therefore, the suction rotor 32, the suction fan 34, and the regeneration fan 35 can be arranged flatly along the back surface 50b, and the humidification unit 30 can be thinned.
　また、第１回転軸３２ｄと第２回転軸３４ｂと第３回転軸３５ｂとが、Ｚ軸方向に延びる一つの直線Ｌ１と直交するように並んでいることから、吸着用ファンロータ３４ａと再生用ファンロータ３５ａとが吸着ロータ３２からＸ軸方向にはみ出さないので、Ｘ軸方向のケーシング５０の寸法Ｍ２を小さくすることができる。 Further, since the first rotation shaft 32d, the second rotation shaft 34b, and the third rotation shaft 35b are arranged so as to be orthogonal to one straight line L1 extending in the Z-axis direction, the suction fan rotor 34a and the regeneration fan rotor 34a Since the fan rotor 35a does not protrude from the suction rotor 32 in the X-axis direction, the dimension M2 of the casing 50 in the X-axis direction can be reduced.
　吸着ロータ３２において、吸着領域では、空気が吸着ロータ３２の表面３２ａから裏面３２ｂに向かって流れ、再生領域では、空気が吸着ロータ３２の裏面３２ｂから表面３２ａに向かって流れる。つまり、吸着用ファン３４と再生用ファン３５は、吸着前空気の気流と再生前空気の気流が対向流となるように配置されている。吸着前空気の気流と再生前空気の気流が対向流となることにより、同じ方向にこれらの気流が流れる場合に比べて加湿能力を向上させることができる。 In the adsorption rotor 32, in the adsorption region, air flows from the front surface 32a of the adsorption rotor 32 toward the back surface 32b, and in the regeneration region, air flows from the back surface 32b of the adsorption rotor 32 toward the front surface 32a. That is, the suction fan 34 and the regeneration fan 35 are arranged so that the airflow of the air before adsorption and the airflow of the air before regeneration are opposed to each other. By making the airflow of the air before adsorption and the airflow of the air before regeneration opposite to each other, the humidifying ability can be improved as compared with the case where these airflows flow in the same direction.
　（４）変形例
　（４－１）変形例１Ａ
　上記第１実施形態では、吸着用ファン３４と再生用ファン３５は、吸着前空気の気流と再生前空気の気流が対向流となるように配置されていたが、吸着用ファン３４と再生用ファン３５は、図１０及び図１１に示されているように、吸着前空気の気流と再生前空気の気流が同じ向きに流れるように配置されてもよい。図１１に示されている加湿ユニット３０Ａでは、正面５０ａに再生前空気取入口５７が形成されている。再生前空気取入口５７は、正面視において、再生用熱交換器３１と実質的に同じ大きさを有している長方形状に形成されている。再生前空気取入口５７にはグリッド５８が取り付けられている。なお、正面５０ａに再生前空気取入口５７を形成して場合でも、上記第１実施形態と同様に、再生前空気取入口を、正面５０ａに近づけて右側面５０ｅ及び左側面５０ｆに設けてもよい。 (4) Modification (4-1) Modification 1A
In the first embodiment, the suction fan 34 and the regeneration fan 35 are arranged so that the airflow of the pre-adsorption air and the airflow of the pre-regeneration air are opposed to each other. As shown in FIGS. 10 and 11, 35 may be arranged such that the airflow of the air before adsorption and the airflow of the air before regeneration flow in the same direction. In the humidifying unit 30A shown in FIG. 11, a pre-regeneration air intake 57 is formed on the front surface 50a. The pre-regeneration air intake 57 is formed in a rectangular shape having substantially the same size as that of the regeneration heat exchanger 31 in a front view. A grid 58 is attached to the pre-regeneration air intake 57. Even when the pre-regeneration air inlet 57 is formed on the front surface 50a, the pre-regeneration air intake port may be provided on the right side surface 50e and the left side surface 50f close to the front surface 50a, as in the first embodiment. Good.
　（４－２）変形例１Ｂ
　上記第１実施形態及び変形例１Ａでは、ケーシング５０，５０Ａの長手方向（寸法Ｍ４の辺が延びる方向）がＺ軸方向に一致するように加湿ユニット３０，３０Ａが取り付けられているが、背面５０ｂに平行な面内で回転させて、例えばケーシング５０，５０Ａの長手方向がＸ軸方向に延びるように加湿ユニット３０，３０Ａが取り付けられてもよい。 (4-2) Modification 1B
In the first embodiment and Modification 1A, the humidifying units 30 and 30A are attached so that the longitudinal direction of the casings 50 and 50A (the direction in which the side of the dimension M4 extends) coincides with the Z-axis direction. For example, the humidifying units 30 and 30A may be attached so that the longitudinal direction of the casings 50 and 50A extends in the X-axis direction.
　（５）特徴
　（５－１）
　第１実施形態の加湿ユニット３０及び変形例１Ａの加湿ユニット３０Ａは、調湿ユニットの一例である。これら加湿ユニット３０，３０Ａにおいては、背面５０ｂに沿った一方向（Ｚ軸方向）に並べて配列されている吸着ロータ３２と吸着用ファンロータ３４ａと再生用ファンロータ３５ａの配列方向視において吸着ロータ３２と吸着用ファンロータ３４ａと再生用ファンロータ３５ａの少なくとも一部が重なるように配置されている。そのため、吸着ロータ３２と吸着用ファン３４と再生用ファン３５が背面５０ｂに沿って平らに並べられることから、配列方向視において吸着ロータ３２と吸着用ファンロータ３４ａと再生用ファンロータ３５ａのうちの少なくとも一つが重ならない場合の厚みに比べて加湿ユニット３０，３０Ａの厚みを薄くすることができ、加湿ユニット３０，３０Ａを薄型化することができている。 (5) Features (5-1)
The humidification unit 30 of 1st Embodiment and the humidification unit 30A of the modification 1A are examples of a humidity control unit. In these humidifying units 30 and 30A, the suction rotor 32 in the arrangement direction of the suction rotor 32, the suction fan rotor 34a, and the regeneration fan rotor 35a arranged side by side in one direction (Z-axis direction) along the back surface 50b. In addition, the suction fan rotor 34a and the regeneration fan rotor 35a are disposed so as to overlap each other. Therefore, since the suction rotor 32, the suction fan 34, and the regeneration fan 35 are arranged flat along the back surface 50b, the suction rotor 32, the suction fan rotor 34a, and the regeneration fan rotor 35a are viewed in the arrangement direction. The thickness of the humidifying units 30 and 30A can be reduced compared to the thickness in the case where at least one does not overlap, and the humidifying units 30 and 30A can be thinned.
　なお、第１回転軸３２ｄと第２回転軸３４ｂと第３回転軸３５ｂが背面に対する垂直方向に延びている場合について説明したが、これらは垂直方向に沿っていればよく、本開示では、第１回転軸３２ｄ、第２回転軸３４ｂ及び第３回転軸３５ｂでは２０度傾くものまで垂直方向に沿うものに含まれる。 In addition, although the case where the first rotating shaft 32d, the second rotating shaft 34b, and the third rotating shaft 35b extend in the vertical direction with respect to the back surface has been described, these may be along the vertical direction. The first rotation shaft 32d, the second rotation shaft 34b, and the third rotation shaft 35b are included in the vertical direction up to a tilt of 20 degrees.
　また、配列方向視において、再生用ファンロータ３５ａが吸着ロータ３２と完全に重なり、再生用ファンロータ３５ａが吸着用ファンロータ３４ａと完全に重なっているが、例えば、再生用ファンロータ３５ａの一部が吸着ロータ３２と重なり、再生用ファンロータ３５ａの一部が吸着用ファンロータ３４ａと重なるように配置されてもよい。例えば、再生用ファンロータ３５ａを背面５０ｂに近づけるようにずらせば、再生用ファンロータ３５ａの一部が吸着ロータ３２と重なり、再生用ファンロータ３５ａの一部が吸着用ファンロータ３４ａと重なるように配置できる。例えば、再生用ファンロータ３５ａを正面５０ａに近づけるようにずらして、再生用ファンロータ３５ａの一部が吸着ロータ３２と重なり、再生用ファンロータ３５ａの全体が吸着用ファンロータ３４ａと重なるように吸着ロータ３２と吸着用ファン３４と再生用ファン３５を配置してもよい。また、例えば、再生用ファンロータ３５ａの全てが吸着ロータ３２と重なり、再生用ファンロータ３５ａの一部が吸着用ファンロータ３４ａと重なるように吸着ロータ３２と吸着用ファン３４と再生用ファン３５を配置することもできる。さらに、吸着ロータ３２の直径を吸着用ファンロータ３４ａの直径よりも小さくして、吸着ロータ３２の全てが吸着用ファンロータ３４ａと重なるように配置してもよい。 Further, when viewed in the arrangement direction, the regeneration fan rotor 35a completely overlaps the suction rotor 32 and the regeneration fan rotor 35a completely overlaps the suction fan rotor 34a. For example, a part of the regeneration fan rotor 35a May be arranged so as to overlap the suction rotor 32 and a part of the regeneration fan rotor 35a to overlap the suction fan rotor 34a. For example, if the reproduction fan rotor 35a is shifted so as to be close to the back surface 50b, a part of the reproduction fan rotor 35a overlaps with the suction rotor 32 and a part of the reproduction fan rotor 35a overlaps with the suction fan rotor 34a. Can be placed. For example, the regeneration fan rotor 35a is shifted so as to be close to the front surface 50a, so that a part of the regeneration fan rotor 35a overlaps with the suction rotor 32, and the entire regeneration fan rotor 35a overlaps with the suction fan rotor 34a. The rotor 32, the suction fan 34, and the regeneration fan 35 may be disposed. Further, for example, the suction rotor 32, the suction fan 34, and the regeneration fan 35 are arranged such that all of the regeneration fan rotor 35a overlaps the suction rotor 32 and a part of the regeneration fan rotor 35a overlaps the suction fan rotor 34a. It can also be arranged. Furthermore, the suction rotor 32 may have a diameter smaller than that of the suction fan rotor 34a, and the suction rotor 32 may be disposed so as to overlap the suction fan rotor 34a.
　（５－２）
　上述の加湿ユニット３０，３０Ａでは、背面５０ｂに対する垂直方向の寸法Ｍ１(図４参照)が背面に対して平行な方向の寸法Ｍ２（図３参照）よりも小さいケーシング５０，５０Ａを用いることで、壁１００からの突出が少ない外観をケーシング５０，５０Ａに与えることができている。その結果、加湿ユニット３０，３０Ａでは、ケーシング５０，５０Ａが、壁面ＷＳに背面５０ｂを対向させて設置し易い外観を持つものとなっている。 (5-2)
In the humidification units 30 and 30A described above, by using the casings 50 and 50A in which the dimension M1 (see FIG. 4) in the direction perpendicular to the back surface 50b is smaller than the dimension M2 in the direction parallel to the back surface (see FIG. 3). The external appearance with few protrusions from the wall 100 can be given to the casings 50 and 50A. As a result, in the humidifying units 30 and 30A, the casings 50 and 50A have an appearance that is easy to install with the rear surface 50b facing the wall surface WS.
　（５－３）
　上述の加湿ユニット３０，３０Ａでは、ケーシング５０，５０Ａが、吸着前空気を取り入れる吸着前空気取入口５２を正面５０ａに有している。このように、吸着前空気取入口５２が正面５０ａに在って吸着ロータ３２の吸着領域の正面への投影面積と同じ大きさの吸着前空気取入口５２が形成できていることから、吸着前空気が吸着ロータ３２に達するまでの流路抵抗を小さくすることができ、吸着用ファン３４に小型のものを用いることができている。その結果、吸着用ファン３４の小型化により加湿ユニット３０，３０Ａの薄型化を向上させることができている。 (5-3)
In the humidification units 30 and 30A described above, the casings 50 and 50A have the pre-adsorption air intake 52 for taking in the pre-adsorption air on the front surface 50a. Thus, since the pre-adsorption air intake 52 is on the front surface 50a and the pre-adsorption air intake 52 having the same size as the projected area on the front surface of the adsorption area of the adsorption rotor 32 can be formed, the pre-adsorption air intake 52 can be formed. The flow resistance until the air reaches the adsorption rotor 32 can be reduced, and a small fan can be used for the adsorption fan 34. As a result, the thinning of the humidifying units 30 and 30A can be improved by reducing the size of the suction fan 34.
　（５－４）
　変形例１Ａの加湿ユニット３０Ａ（調湿ユニットの一例）のケーシング５０Ａのように、再生前空気を取り入れる再生前空気取入口５７がケーシング５０Ａの正面５０ａに形成されている場合には、吸着ロータから吸着用ファンに向かう流路と吸着ロータから再生用ファンに向かう流路が同じ側に設けられることから、ケーシング５０Ａの厚みを薄くし易くなる（背面５０ｂに対する垂直方向の寸法Ｍ３を小さくし易くなる）。 (5-4)
When the pre-regeneration air intake 57 for taking in the pre-regeneration air is formed on the front surface 50a of the casing 50A like the casing 50A of the humidification unit 30A (an example of the humidity control unit) of the modified example 1A, Since the flow path toward the suction fan and the flow path from the suction rotor to the regeneration fan are provided on the same side, the thickness of the casing 50A can be easily reduced (the dimension M3 in the direction perpendicular to the back surface 50b can be easily reduced). ).
　（５－５）
　上述の加湿ユニット３０では、吸着前空気取入口５２が正面５０ａに形成されていることから、再生前空気が吸着ロータ３２の表面３２ａから入って裏面３２ｂから出るので、ケーシング５０は、再生前空気を取り入れる再生前空気取入口５４を、背面５０ｂと正面５０ａとの間の側面である右側面５０ｅと左側面５０ｆに有し、吸着用ファン３４と再生用ファン３５は、吸着前空気の気流と再生前空気の気流が対向流となるように配置することができている。着前空気の気流と再生前空気の気流が対向流となることにより、加湿ユニット３０の加湿能力を向上させることができ、調湿能力が高く且つ薄型化された調湿ユニットである加湿ユニット３０が提供できる。 (5-5)
In the humidification unit 30 described above, since the pre-adsorption air intake 52 is formed on the front surface 50a, the pre-regeneration air enters from the front surface 32a of the adsorption rotor 32 and exits from the back surface 32b. Are provided on the right side surface 50e and the left side surface 50f, which are the side surfaces between the back surface 50b and the front surface 50a, and the suction fan 34 and the regeneration fan 35 It can arrange | position so that the airflow of the air before reproduction | regeneration may become a counterflow. When the airflow before wearing and the airflow before regeneration are opposed to each other, the humidifying capacity of the humidifying unit 30 can be improved, and the humidifying unit 30 is a highly humidified and thinned humidity control unit. Can be provided.
　（５－６）
　上述の加湿ユニット３０，３０Ａでは、吸着ロータ３２を挟んで再生用ファン３５が上に位置するとともに吸着用ファン３４が下に位置する取り付けができるように構成されている。このように、再生用ファン３５が上に位置することで、壁面ＷＳの上方に形成された貫通孔１０１と再生用ファン３５とを近づけ易くなり、貫通孔１０１を通過する、再生用ファン３５から例えば室内まで吹き出す再生後空気の流路である例えば加湿ホース３６を短くすることができる。その結果、再生用ファン３５から吹出される再生後空気の流路を短くして再生後空気に起因して起こる結露による不具合を抑制することができる。 (5-6)
The humidification units 30 and 30A described above are configured so that the regeneration fan 35 is located above the suction rotor 32 and the suction fan 34 is located below. As described above, the reproduction fan 35 is located on the upper side, so that the through hole 101 formed above the wall surface WS and the reproduction fan 35 can be easily brought close to each other. For example, the humidification hose 36 that is a flow path of the regenerated air that blows out into the room can be shortened. As a result, the flow path of the post-regeneration air blown from the regeneration fan 35 can be shortened to suppress problems caused by condensation caused by the post-regeneration air.
　（５－７）
　上述の加湿ユニット３０，３０Ａは、室外機２と室内機４を備える空気調和装置１に取り付け可能に構成されている。加湿ユニット３０，３０Ａは、ケーシング５０，５０Ａが室外ＯＤに設置されて、再生用ファン３５によって室内機４に吹き出される再生後空気により室内ＩＤを加湿するとともに、吸着用ファン３４によって吸着後空気を室外ＯＤに吹き出す。ケーシング５０，５０Ａが室外ＯＤに設置されることにより、調湿ユニットである加湿ユニット３０，３０Ａによる室内ＩＤの加湿において吸着用ファン３４により吸着前空気を室外ＯＤから取り入れ易くなり、吸着用ファン３４を小型化して加湿ユニット３０，３０Ａを薄型化し易くなっている。 (5-7)
The humidification units 30 and 30A described above are configured to be attachable to the air conditioner 1 including the outdoor unit 2 and the indoor unit 4. In the humidifying units 30 and 30A, the casings 50 and 50A are installed in the outdoor OD, the indoor ID is humidified by the regenerated air blown out to the indoor unit 4 by the regeneration fan 35, and the air after adsorption by the adsorption fan 34 To the outdoor OD. Since the casings 50 and 50A are installed in the outdoor OD, it becomes easy to take the pre-adsorption air from the outdoor OD by the adsorption fan 34 when humidifying the indoor ID by the humidification units 30 and 30A that are humidity control units. It is easy to make the humidification units 30 and 30A thinner.
　（５－８）
　上述の加湿ユニット３０，３０Ａは、ケーシング５０，５０Ａが、室外機２よりも室内機４に近い位置に配置されている。室外機２よりも室内機４に近い位置にケーシング５０，５０が配置されることにより、室外機２に加湿ユニットが一体化されている従来例に比べて再生用ファン３５が室内機４の近くに位置することになるから、再生用ファン３５から吹き出す再生後空気を室内機４に導く流路である例えば加湿ホース３６を短くすることができる。その結果、再生用ファン３５から吹出される再生後空気の流路を短くして再生後空気に起因して起こる結露による不具合を抑制することができる。 (5-8)
In the humidification units 30 and 30A described above, the casings 50 and 50A are arranged at positions closer to the indoor unit 4 than to the outdoor unit 2. By arranging the casings 50, 50 closer to the indoor unit 4 than the outdoor unit 2, the regeneration fan 35 is closer to the indoor unit 4 than the conventional example in which the humidifying unit is integrated with the outdoor unit 2. Therefore, for example, the humidification hose 36 which is a flow path for guiding the regenerated air blown from the regeneration fan 35 to the indoor unit 4 can be shortened. As a result, the flow path of the post-regeneration air blown from the regeneration fan 35 can be shortened to suppress problems caused by condensation caused by the post-regeneration air.
　＜第２実施形態＞
　（６）全体構成
　第２実施形態では、空気調和装置１に組み込まれた加湿ユニットの他の形態を説明している。図１２には第２実施形態に係る加湿ユニット３０Ｂを正面から見た状態が示され、図１３には加湿ユニット３０Ｂの右側面５０ｅが示され、図１４には加湿ユニット３０Ｂの左側面５０ｆが示され、図１５には加湿ユニット３０Ｂの下側面５０ｄが示されている。また、図１６には、図１２のＩＩ－ＩＩ線に沿って加湿ユニット３０Ｂを切断して右側から見た状態が示され、図１７には、図１２のＩＩ－ＩＩ線に沿って加湿ユニット３０Ｂを切断して左側から見た状態が示されている。 Second Embodiment
(6) Overall Configuration In the second embodiment, another form of the humidifying unit incorporated in the air conditioner 1 is described. FIG. 12 shows the humidification unit 30B according to the second embodiment as viewed from the front, FIG. 13 shows the right side surface 50e of the humidification unit 30B, and FIG. 14 shows the left side surface 50f of the humidification unit 30B. FIG. 15 shows a lower side surface 50d of the humidifying unit 30B. FIG. 16 shows a state in which the humidification unit 30B is cut along the line II-II in FIG. 12 and viewed from the right side, and FIG. 17 shows the humidification unit along the line II-II in FIG. The state which cut | disconnected 30B and was seen from the left side is shown.
　図１６及び図１７を見れば分かるように、第２実施形態では、ケーシング５０Ｂの背面に対して、吸着ロータ３２が斜めに配置されている。吸着ロータ３２が斜めに配置されているので、第１実施形態のケーシング５０におけるＺ軸方向の寸法Ｍ４に比べて、第２実施形態のケーシング５０ＢにおけるＺ軸方向の寸法Ｍ５を小さくすることができている。 As can be seen from FIGS. 16 and 17, in the second embodiment, the suction rotor 32 is disposed obliquely with respect to the back surface of the casing 50B. Since the suction rotor 32 is disposed obliquely, the dimension M5 in the Z-axis direction in the casing 50B of the second embodiment can be made smaller than the dimension M4 in the Z-axis direction in the casing 50 of the first embodiment. ing.
　第２実施形態の加湿ユニット３０Ｂが組み込まれた空気調和装置は、例えば、第１実施形態の加湿ユニット３０が組み込まれた空気調和装置１において加湿ユニット３０と加湿ユニット３０Ｂを入れ替えることができ、そのように入れ替えた場合の空気調和装置の構成は図１と同じになる。であるから、第２実施形態の加湿ユニット３０Ｂが空気調和装置に組み込まれたときの構成については説明を省略する。同様に、第２実施形態の加湿ユニット３０Ｂが組み込まれた空気調和装置の動作についても同様であるので、第２実施形態の加湿ユニット３０Ｂが組み込まれた空気調和装置の動作の説明を省略する。 The air conditioning apparatus incorporating the humidifying unit 30B of the second embodiment can replace the humidifying unit 30 and the humidifying unit 30B in the air conditioning apparatus 1 incorporating the humidifying unit 30 of the first embodiment, for example. Thus, the configuration of the air conditioning apparatus when replaced is the same as in FIG. Therefore, description is abbreviate | omitted about the structure when the humidification unit 30B of 2nd Embodiment is integrated in an air conditioning apparatus. Similarly, since the operation of the air conditioner incorporating the humidifying unit 30B of the second embodiment is the same, the description of the operation of the air conditioner incorporating the humidifying unit 30B of the second embodiment is omitted.
　加湿ユニット３０Ｂは、加湿ユニット３０と同様に、再生用熱交換器３１と吸着ロータ３２とロータ用モータ３３と吸着用ファン３４と再生用ファン３５と加湿ホース３６とを備えている。加湿ユニット３０Ｂと加湿ユニット３０では、吸着ロータ３２が傾斜しているために、再生用熱交換器３１と吸着ロータ３２とロータ用モータ３３と吸着用ファン３４と再生用ファン３５と加湿ホース３６の配置や構造が異なるので、これらの異なる点について以下に説明する。 The humidification unit 30 </ b> B includes a regeneration heat exchanger 31, an adsorption rotor 32, a rotor motor 33, an adsorption fan 34, a regeneration fan 35, and a humidification hose 36, similarly to the humidification unit 30. In the humidification unit 30 </ b> B and the humidification unit 30, since the adsorption rotor 32 is inclined, the regeneration heat exchanger 31, the adsorption rotor 32, the rotor motor 33, the adsorption fan 34, the regeneration fan 35, and the humidification hose 36. Since the arrangement and structure are different, these different points will be described below.
　（７）詳細構成
　（７－１）各部の配置と構造
　図１７に示されているように、吸着ロータ３２は、背面５０ｂに対して傾斜した第１回転軸３２ｄの周りで回転する。例えば、第１回転軸３２ｄとＸ軸とのなす角αが１０度～３０度になるように吸着ロータ３２が配置される。ここでは、第１回転軸３２ｄとＸ軸とのなす角αが約１５度になるように配置されている。このように配置された吸着ロータ３２の裏面３２ｂに平行に再生用熱交換器３１が配置されている。例えば、再生用熱交換器３１のフィンの正面側端部の包絡面３１Ｐが実質的に吸着ロータ３２の裏面３２ｂに平行になっている。再生用熱交換器３１については、吸着ロータ３２に再生用熱交換器３１を近づけて熱エネルギーのロスを小さくするのに、吸着ロータ３２に沿うように斜めに配置されていることが好ましい。この場合、吸着ロータ３２の裏面３２ｂに対して±１０度傾くものも吸着ロータ３２に沿うものに含まれる。この再生用熱交換器３１は、重心がケーシング５０Ｂの正面５０ａよりも背面５０ｂに近い点に位置するように配置されている。再生用熱交換器３１の重心がケーシング５０Ｂの背面５０ｂに近い点に位置すると、重心が正面５０ａに近いところにある場合に比べて加湿ユニット３０Ｂを壁１００から離す方向に働く力のモーメントが小さくなるので、壁面ＷＳに背面５０ｂを対向させて設置し易くなる。 (7) Detailed Configuration (7-1) Arrangement and Structure of Each Part As shown in FIG. 17, the suction rotor 32 rotates around a first rotation shaft 32d inclined with respect to the back surface 50b. For example, the suction rotor 32 is arranged so that the angle α formed by the first rotation shaft 32d and the X axis is 10 degrees to 30 degrees. Here, the angle α formed by the first rotation shaft 32d and the X axis is arranged to be about 15 degrees. The regeneration heat exchanger 31 is arranged in parallel to the back surface 32b of the adsorption rotor 32 arranged in this way. For example, the envelope surface 31 </ b> P at the front side end of the fin of the regeneration heat exchanger 31 is substantially parallel to the back surface 32 b of the adsorption rotor 32. The regeneration heat exchanger 31 is preferably disposed obliquely along the adsorption rotor 32 in order to reduce the heat energy loss by bringing the regeneration heat exchanger 31 close to the adsorption rotor 32. In this case, those inclined by ± 10 degrees with respect to the back surface 32 b of the adsorption rotor 32 are also included in the arrangement along the adsorption rotor 32. The regeneration heat exchanger 31 is arranged so that the center of gravity is located closer to the back surface 50b than the front surface 50a of the casing 50B. When the center of gravity of the regeneration heat exchanger 31 is located at a point close to the back surface 50b of the casing 50B, the moment of force acting in the direction of moving the humidifying unit 30B away from the wall 100 is smaller than when the center of gravity is near the front surface 50a. Therefore, it becomes easy to install the back surface 50b facing the wall surface WS.
　再生用熱交換器３１に送られる再生前空気は、右側面５０ｅ及び左側面５０ｆに形成されている再生前空気取入口５４から取り入れられる。再生前空気取入口５４は、吸着ロータ３２の傾斜に沿って斜めにカットされた斜めカット部５４ａを含んでいる。このような斜めカット部５４ａによって開口部が広がる分だけ再生前空気取入口５４が大きくなっており、再生前空気の流路抵抗が小さくなっている。 The pre-regeneration air sent to the regeneration heat exchanger 31 is taken in from the pre-regeneration air intake 54 formed on the right side surface 50e and the left side surface 50f. The pre-regeneration air intake 54 includes an oblique cut portion 54 a that is obliquely cut along the inclination of the adsorption rotor 32. The pre-regeneration air intake 54 is increased by the amount of the opening being expanded by such an oblique cut portion 54a, and the flow path resistance of the pre-regeneration air is reduced.
　吸着用ファンロータ３４ａの第２回転軸３４ｂ及び再生用ファンロータ３５ａの第３回転軸３５ｂは、いずれも背面５０ｂに対する垂直方向（Ｙ軸方向）に延びている。言い換えると、吸着用ファンロータ３４ａも再生用ファンロータ３５ａも背面５０ｂに平行な面内で回転するように、吸着用ファン３４及び再生用ファン３５が配置されている。また、吸着用ファン３４及び再生用ファン３５は、それぞれの重心がケーシング５０Ｂの正面５０ａよりも背面５０ｂに近い点に位置するように配置されている。重量物である吸着用ファン３４の重心と再生用ファン３５の重心がケーシング５０Ｂの背面５０ｂに近い点に位置すると、重心が正面５０ａに近いところにある場合に比べて加湿ユニット３０Ｂを壁１００から離す方向に働く力のモーメントが小さくなるので、壁面ＷＳに背面５０ｂを対向させて設置し易くなる。 The second rotation shaft 34b of the suction fan rotor 34a and the third rotation shaft 35b of the regeneration fan rotor 35a both extend in a direction perpendicular to the back surface 50b (Y-axis direction). In other words, the suction fan 34 and the regeneration fan 35 are arranged so that both the suction fan rotor 34a and the regeneration fan rotor 35a rotate in a plane parallel to the back surface 50b. Further, the suction fan 34 and the regeneration fan 35 are arranged such that the center of gravity of each of them is located closer to the back surface 50b than the front surface 50a of the casing 50B. When the gravity center of the suction fan 34 and the gravity fan of the regeneration fan 35, which are heavy objects, are located at a point close to the back surface 50b of the casing 50B, the humidifying unit 30B is separated from the wall 100 as compared with the case where the gravity center is close to the front surface 50a. Since the moment of the force acting in the separating direction becomes small, it becomes easy to install the back surface 50b facing the wall surface WS.
　図１６に示されているように、吸着用ファン３４は、ベルマウス３４ｇの吸込円孔３４ｆの領域ＲＥ１と吸着ロータ３２の一部領域ＲＥ２が正面視において重なるように配置されている。吸着ロータ３２の一部領域ＲＥ２は、吸着用ファン３４とケーシング５０Ｂの正面５０ａの間に配置されている。吸着用ファン３４とケーシング５０Ｂの正面５０ａとの間に吸着ロータ３２の一部領域ＲＥ２が配置されることで、吸着ロータに吸着前空気を導くときの流路抵抗を低く抑えることができ、吸着用ファン３４の小型化ができている。 As shown in FIG. 16, the suction fan 34 is arranged such that the region RE1 of the suction circular hole 34f of the bell mouth 34g and the partial region RE2 of the suction rotor 32 overlap in front view. A partial region RE2 of the suction rotor 32 is disposed between the suction fan 34 and the front surface 50a of the casing 50B. Since the partial region RE2 of the suction rotor 32 is disposed between the suction fan 34 and the front surface 50a of the casing 50B, the flow path resistance when the pre-adsorption air is guided to the suction rotor can be suppressed to a low level. The fan 34 can be downsized.
　そして、図１６に示されている吸着ロータ３２の裏面３２ｂのうち、ベルマウス３４ｇの吸込円孔３４ｆから最も遠い最離反箇所Ｐ１が吸込円孔３４ｆの半径ｒ１の６０％離れている。吸着用ファン３４のベルマウス３４ｇの吸込円孔３４ｆのうちの吸着ロータ３２と重なっていない領域について吸着ロータ３２と吸着用ファン３４との間で空気を流れ易くするためには、半径ｒ１の１０％以上離れるように配置されることが好ましい。また、吸着ロータ３２が吸着用ファン３４から離れすぎると、加湿ユニット３０Ｂの薄型化が難しくなるので、吸着ロータ３２は、例えば、最離反箇所Ｐ１が吸込円孔３４ｆの半径ｒ１の４０％以上離れる場合においては、吸込円孔３４ｆから最も近い最近接箇所Ｐ２が離れる距離は、吸込円孔３４ｆの半径ｒ１の４０％未満になるように設定される。ここでは、吸込円孔３４ｆから最近接箇所Ｐ２までの距離が吸込円孔３４ｆの半径ｒ１の約３５％になっている。 In the back surface 32b of the suction rotor 32 shown in FIG. 16, the farthest away point P1 from the suction circular hole 34f of the bell mouth 34g is 60% away from the radius r1 of the suction circular hole 34f. In order to make air easily flow between the suction rotor 32 and the suction fan 34 in the suction circular hole 34f of the bell mouth 34g of the suction fan 34 that does not overlap with the suction rotor 32, a radius r1 of 10 is used. It is preferable that they are arranged so that they are separated by at least%. Further, if the suction rotor 32 is too far from the suction fan 34, it is difficult to reduce the thickness of the humidifying unit 30B. In some cases, the distance at which the nearest closest point P2 is separated from the suction circular hole 34f is set to be less than 40% of the radius r1 of the suction circular hole 34f. Here, the distance from the suction circular hole 34f to the closest point P2 is about 35% of the radius r1 of the suction circular hole 34f.
　再生用ファン３５は、再生用熱交換器３１から吸着ロータ３２の裏面３２ｂ、表面３２ａの順に通過してきた再生後空気を、ケーシング５０Ｂの正面５０ａに沿って配置されている再生後空気用ダクト３５ｅで吸着ロータ３２の吸込口３５ｆに送る。再生用ファン３５の再生用ファンロータ３５ａには、正面５０ａから背面５０ｂに向かう方向に再生後空気が吸入される。この場合も、吸着ロータ３２において、吸着領域では、空気が吸着ロータ３２の表面３２ａから裏面３２ｂに向かって流れ、再生領域では、空気が吸着ロータ３２の裏面３２ｂから表面３２ａに向かって流れる。つまり、吸着用ファン３４と再生用ファン３５は、吸着前空気の気流と再生前空気の気流が対向流となるように配置されている。 The regeneration fan 35 is a post-regeneration air duct 35e that is disposed along the front surface 50a of the casing 50B, after the regeneration air that has passed from the heat exchanger 31 for regeneration to the back surface 32b and the front surface 32a of the adsorption rotor 32 in this order. To the suction port 35 f of the suction rotor 32. The regeneration fan rotor 35a of the regeneration fan 35 draws post-regeneration air in the direction from the front surface 50a to the rear surface 50b. Also in this case, in the adsorption rotor 32, in the adsorption region, air flows from the front surface 32a of the adsorption rotor 32 toward the back surface 32b, and in the regeneration region, air flows from the back surface 32b of the adsorption rotor 32 toward the front surface 32a. That is, the suction fan 34 and the regeneration fan 35 are arranged so that the airflow of the air before adsorption and the airflow of the air before regeneration are opposed to each other.
　（７－２）吸着ロータ３２と吸着用ファン３４と再生用ファン３５の位置関係
　第２実施形態においても第１実施形態と同様に、吸着ロータ３２と吸着用ファンロータ３４ａと再生用ファンロータ３５ａは、背面５０ｂに沿って一方向（Ｚ軸方向）に並べて配列されている。吸着ロータ３２の第１回転軸３２ｄと吸着用ファンロータ３４ａの第２回転軸３４ｂと再生用ファンロータ３５ａの第３回転軸３５ｂとが、Ｚ軸方向に延びる一つの直線Ｌ２を通るＹＺ平面内に並んでいる。吸着ロータ３２と吸着用ファンロータ３４ａと再生用ファンロータ３５ａの配列方向視、つまり直線Ｌ２に沿って下側面５０ｄから上側面５０ｃの方を見ると、図１８に示されているように、吸着ロータ３２の一部と吸着用ファンロータ３４ａの一部とが再生用ファンロータ３５ａの一部と重なり、正面５０ａと背面５０ｂの距離を縮めてＹ軸方向の寸法Ｍ６を小さくでき、加湿ユニット３０Ｂが薄型化できている。 (7-2) Positional relationship among the suction rotor 32, the suction fan 34, and the regeneration fan 35 Also in the second embodiment, as in the first embodiment, the suction rotor 32, the suction fan rotor 34a, and the regeneration fan rotor 35a. Are arranged in one direction (Z-axis direction) along the back surface 50b. In the YZ plane, the first rotation shaft 32d of the suction rotor 32, the second rotation shaft 34b of the suction fan rotor 34a, and the third rotation shaft 35b of the regeneration fan rotor 35a pass through one straight line L2 extending in the Z-axis direction. Are lined up. When the suction rotor 32, the suction fan rotor 34a, and the regeneration fan rotor 35a are viewed in the arrangement direction, that is, when viewed from the lower side surface 50d to the upper side surface 50c along the straight line L2, as shown in FIG. A part of the rotor 32 and a part of the suction fan rotor 34a overlap with a part of the regeneration fan rotor 35a, and the distance M between the front surface 50a and the back surface 50b can be shortened to reduce the dimension M6 in the Y-axis direction. Can be made thinner.
　また、第１回転軸３２ｄと第２回転軸３４ｂとの第３回転軸３５ｂとが、Ｚ軸方向に延びる一つの直線Ｌ２を通るＹＺ平面内に並んでいることから、吸着用ファンロータ３４ａと再生用ファンロータ３５ａとが吸着ロータ３２からＸ軸方向にはみ出さないので、Ｘ軸方向のケーシング５０の寸法Ｍ７を小さくすることができる。 Further, since the third rotation shaft 35b of the first rotation shaft 32d and the second rotation shaft 34b is arranged in the YZ plane passing through one straight line L2 extending in the Z-axis direction, the suction fan rotor 34a and Since the reproduction fan rotor 35a does not protrude from the suction rotor 32 in the X-axis direction, the dimension M7 of the casing 50 in the X-axis direction can be reduced.
　（８）変形例
　（８－１）変形例２Ａ
　上記第２実施形態では、吸着用ファン３４と再生用ファン３５は、吸着前空気の気流と再生前空気の気流が対向流となるように配置されていたが、吸着用ファン３４と再生用ファン３５は、図１９に示されているように、吸着前空気の気流と再生前空気の気流が同じ向きに流れるように配置されてもよい。図１９に示されている加湿ユニット３０Ｃでは、ケーシング５０Ｃの正面５０ａに再生前空気取入口５７が形成されている。再生前空気取入口５７は、正面視において、再生用熱交換器３１と実質的に同じ大きさを有している長方形状に形成されている。再生前空気取入口５７にはグリッド５８が取り付けられている。なお、正面５０ａに再生前空気取入口５７を形成して場合でも、上記第２実施形態と同様に、再生前空気取入口を正面５０ａに近づけて右側面５０ｅ及び左側面５０ｆに設けてもよい。 (8) Modification (8-1) Modification 2A
In the second embodiment, the suction fan 34 and the regeneration fan 35 are arranged so that the airflow of the pre-adsorption air and the airflow of the pre-regeneration air are opposed to each other. As shown in FIG. 19, the air flow 35 may be arranged so that the airflow before the adsorption and the airflow before the regeneration flow in the same direction. In the humidifying unit 30C shown in FIG. 19, a pre-regeneration air intake 57 is formed on the front surface 50a of the casing 50C. The pre-regeneration air intake 57 is formed in a rectangular shape having substantially the same size as that of the regeneration heat exchanger 31 in a front view. A grid 58 is attached to the pre-regeneration air intake 57. Even when the pre-regeneration air inlet 57 is formed on the front surface 50a, the pre-regeneration air intake port may be provided on the right side surface 50e and the left side surface 50f close to the front surface 50a as in the second embodiment. .
　（８－２）変形例２Ｂ
　上記第２実施形態及び変形例２Ａでは、ケーシング５０Ｂ，５０Ｃの長手方向（寸法Ｍ５の辺が延びる方向）がＺ軸方向に一致するように加湿ユニット３０Ｂ，３０Ｃが取り付けられているが、背面５０ｂに平行な面内で回転させて、例えばケーシング５０Ｂ，５０Ｃの長手方向がＸ軸方向に延びるように加湿ユニット３０Ｂ，３０Ｃが取り付けられてもよい。 (8-2) Modification 2B
In the second embodiment and Modification 2A, the humidifying units 30B and 30C are attached so that the longitudinal direction of the casings 50B and 50C (the direction in which the side of the dimension M5 extends) coincides with the Z-axis direction. For example, the humidifying units 30B and 30C may be attached such that the longitudinal directions of the casings 50B and 50C extend in the X-axis direction.
　（９）特徴
　第２実施形態の加湿ユニット３０Ｂは、上述の（５－１）～（５－３）及び（５－５）～（５－８）で説明した第１実施形態の加湿ユニット３０と同様の特徴を有していることが明らかであるので、これらの特徴の説明を省略する。また、変形例２Ａの加湿ユニット３０Ｃは、上述の（５－１）～（５－４）及び（５－６）～（５－８）で説明した変形例１Ａの加湿ユニット３０Ａと同様の特徴を有していることが明らかであるので、これらの説明を省略する。 (9) Features The humidifying unit 30B of the second embodiment is the humidifying unit 30 of the first embodiment described in the above (5-1) to (5-3) and (5-5) to (5-8). Since it is clear that they have the same characteristics as those described above, description of these characteristics will be omitted. Further, the humidifying unit 30C of the modified example 2A has the same characteristics as the humidifying unit 30A of the modified example 1A described in the above (5-1) to (5-4) and (5-6) to (5-8). Since it is clear that these are included, these descriptions are omitted.
　（９－１）
　第２実施形態の加湿ユニット３０Ｂ及び変形例２Ａの加湿ユニット３０Ｃは、調湿ユニットの一例である。加湿ユニット３０Ｂ，３０Ｃの吸着ロータ３２は、背面５０ｂに対して斜めに配置され、ケーシング５０Ｂ，５０Ｃの再生前空気取入口５４は、右側面５０ｅ及び左側面５０ｆに吸着ロータ３２の傾斜に沿って斜めにカットされた斜めカット部５４ａを含む。これら斜めカット部５４ａによって開口部が広がる分だけ再生前空気取入口５４を大きくすることができ、再生前空気の流路抵抗を小さくして再生用ファン３５の小型化が容易になることで、加湿ユニット３０Ｂ，３０Ｃの薄型化が容易になっている。 (9-1)
The humidification unit 30B of 2nd Embodiment and the humidification unit 30C of the modification 2A are examples of a humidity control unit. The adsorption rotor 32 of the humidifying units 30B and 30C is disposed obliquely with respect to the back surface 50b, and the pre-regeneration air intake 54 of the casings 50B and 50C is along the inclination of the adsorption rotor 32 on the right side surface 50e and the left side surface 50f. An oblique cut portion 54a cut obliquely is included. The pre-regeneration air intake 54 can be enlarged by the amount of the opening that is widened by these oblique cut portions 54a, and the flow resistance of the pre-regeneration air can be reduced to facilitate the miniaturization of the regeneration fan 35. The humidification units 30B and 30C can be easily reduced in thickness.

　（１０）全体構成
　上述の加湿ユニット３０，３０Ａ～３０Ｃは、空気調和装置１に組み込まれて室内ＩＤの加湿を行う調湿ユニットの一例として説明されているが、これらの加湿ユニット３０，３０Ａ～３０Ｃと同じユニットを室内ＩＤに設置して再生後空気を室外に排出することで、除湿ユニットとして用いることもできる。 <Third Embodiment>
(10) Overall configuration The above-described humidifying units 30, 30A to 30C are described as an example of a humidity control unit that is incorporated in the air conditioner 1 and humidifies the room ID, but these humidifying units 30, 30A to 30C By installing the same unit as 30C in the room ID and discharging the air after regeneration outside the room, it can also be used as a dehumidifying unit.
　図２０には、除湿ユニット３０Ｄが取り付けられた空気調和装置１が示されている。また、図２１には、図２０に示されている除湿ユニット３０Ｄの構成の概念が示されている。この除湿ユニット３０Ｄが第３実施形態における調湿ユニットの一例である。第３実施形態の除湿ユニット３０Ｄは、第１実施形態の加湿ユニット３０と同様に再生用熱交換器３１と吸着ロータ３２とロータ用モータ３３と吸着用ファン３４と再生用ファン３５とケーシング５０とを備え、第１実施形態の加湿ユニット３０が備える加湿ホース３６の代わりに排気ホース３７を備えている。排気ホース３７以外の構成は、第３実施形態の除湿ユニット３０Ｄと第１実施形態の加湿ユニット３０とは同じであるので説明を省略する。 FIG. 20 shows the air conditioner 1 to which the dehumidifying unit 30D is attached. FIG. 21 shows the concept of the configuration of the dehumidifying unit 30D shown in FIG. The dehumidifying unit 30D is an example of a humidity control unit in the third embodiment. The dehumidifying unit 30D of the third embodiment is similar to the humidifying unit 30 of the first embodiment in that the regeneration heat exchanger 31, the adsorption rotor 32, the rotor motor 33, the adsorption fan 34, the regeneration fan 35, and the casing 50 The exhaust hose 37 is provided instead of the humidification hose 36 provided in the humidification unit 30 of the first embodiment.
