空気調和機air conditioner
　本開示は、空気調和機に関する。 The present disclosure relates to air conditioners.
　従来、例えば、特許文献１に記載するように、空気調和対象の室内に配置される室内機と、室外に配置される室外機とから構成される空気調和機が知られている。この空気調和機は、室外機から室内機に加湿された室外空気または除湿された室外空気を供給するように構成されている。具体的には、吸収材が回転し、ヒータによって加熱された室外空気が吸収材の一部分を通過し、加熱されていない室外空気が吸収材の残りの部分を通過する。ヒータによって加熱された室外空気（加湿された室外空気）または加熱されていない室外空気（除湿された室外空気）の一方が室内機に供給され、他方が室外に排出される。 Conventionally, as described in Patent Document 1, for example, an air conditioner is known that is composed of an indoor unit arranged inside a room to be air-conditioned and an outdoor unit arranged outdoors. This air conditioner is configured to supply humidified outdoor air or dehumidified outdoor air from an outdoor unit to an indoor unit. Specifically, the absorbent rotates, outdoor air heated by the heater passes through a portion of the absorbent, and unheated outdoor air passes through the remaining portion of the absorbent. One of the outdoor air heated by the heater (humidified outdoor air) and the unheated outdoor air (dehumidified outdoor air) is supplied to the indoor unit, and the other is discharged outdoors.

　ところで、特許文献１に記載された空気調和機の場合、吸収材は回転する。そのために、吸収材の外周面とその外周面に対向する対向部材との間にクリアランスが存在する。ヒータによって加熱された室外空気の一部がクリアランスを介して吸収材をバイパスすると、室内機に供給される室外空気の加湿量が減少する。その結果、室内の加湿効率が低下する。 By the way, in the case of the air conditioner described in Patent Document 1, the absorbent rotates. Therefore, there is a clearance between the outer peripheral surface of the absorber and the opposing member facing the outer peripheral surface. When part of the outdoor air heated by the heater bypasses the absorbent through the clearance, the amount of humidification of the outdoor air supplied to the indoor unit is reduced. As a result, the indoor humidification efficiency decreases.
　そこで、本開示は、室外空気が回転する吸収材を通過することによって加湿されて室内機に供給される空気調和機において、室外空気が吸収材をバイパスすることを抑制することが可能な空気調和機を提供する。 Therefore, the present disclosure provides an air conditioner in which outdoor air is humidified by passing through a rotating absorbent and supplied to an indoor unit, and is capable of suppressing the outdoor air from bypassing the absorbent. provide the machine.

　（実施の形態）
　以下、本開示の一実施の形態について図面を参照しながら説明する。 (Embodiment)
An embodiment of the present disclosure will be described below with reference to the drawings.
　図１は、本開示の一実施の形態に係る空気調和機１０の構成を示す概略図である。 FIG. 1 is a schematic diagram showing the configuration of an air conditioner 10 according to an embodiment of the present disclosure.
　図１に示すように、本実施の形態に係る空気調和機１０は、空調対象の室内Ｒｉｎに配置される室内機２０と、室外Ｒｏｕｔに配置される室外機３０とを有する。 As shown in FIG. 1, the air conditioner 10 according to the present embodiment has an indoor unit 20 arranged in the indoor Rin to be air-conditioned, and an outdoor unit 30 arranged in the outdoor Rout.
　室内機２０には、室内空気Ａ１と熱交換を行う室内熱交換器２２と、室内空気Ａ１を室内機２０内に誘引するとともに、室内熱交換器２２と熱交換した後の室内空気Ａ１を室内Ｒｉｎに吹き出すファン２４とが設けられている。 The indoor unit 20 includes an indoor heat exchanger 22 that exchanges heat with the indoor air A1, and invites the indoor air A1 into the indoor unit 20, and the indoor air A1 after heat exchange with the indoor heat exchanger 22 is introduced into the room. A fan 24 that blows to Rin is provided.
　室外機３０には、室外空気Ａ２と熱交換を行う室外熱交換器３２と、室外空気Ａ２を室外機３０内に誘引するとともに、室外熱交換器３２と熱交換した後の室外空気Ａ２を室外Ｒｏｕｔに吹き出すファン３４とが設けられている。また、室外機３０には、室内熱交換器２２および室外熱交換器３２と冷凍サイクルを実行する圧縮機３６、膨張弁３８、および四方弁４０が設けられている。 The outdoor unit 30 includes an outdoor heat exchanger 32 that exchanges heat with the outdoor air A2, and invites the outdoor air A2 into the outdoor unit 30. A fan 34 blowing to Rout is provided. In addition, the outdoor unit 30 is provided with a compressor 36, an expansion valve 38, and a four-way valve 40 for executing a refrigerating cycle with the indoor heat exchanger 22 and the outdoor heat exchanger 32.
　室内熱交換器２２、室外熱交換器３２、圧縮機３６、膨張弁３８、および四方弁４０それぞれは、冷媒が流れる冷媒配管によって接続されている。冷房運転および除湿運転（弱冷房運転）の場合、空気調和機１０は、冷媒が圧縮機３６から四方弁４０、室外熱交換器３２、膨張弁３８、室内熱交換器２２を順に流れて圧縮機３６に戻る冷凍サイクルを実行する。暖房運転の場合、空気調和機１０は、冷媒が圧縮機３６から四方弁４０、室内熱交換器２２、膨張弁３８、室外熱交換器３２を順に流れて圧縮機３６に戻る冷凍サイクルを実行する。 The indoor heat exchanger 22, the outdoor heat exchanger 32, the compressor 36, the expansion valve 38, and the four-way valve 40 are connected by refrigerant pipes through which refrigerant flows. In the case of cooling operation and dehumidification operation (weak cooling operation), the air conditioner 10 is configured such that the refrigerant flows from the compressor 36 through the four-way valve 40, the outdoor heat exchanger 32, the expansion valve 38, and the indoor heat exchanger 22 in order. Execute the freeze cycle back to 36. In the case of heating operation, the air conditioner 10 executes a refrigeration cycle in which refrigerant flows from the compressor 36 through the four-way valve 40, the indoor heat exchanger 22, the expansion valve 38, the outdoor heat exchanger 32 in order, and then returns to the compressor 36. .
　空気調和機１０は、冷凍サイクルによる空調運転の他に、室外空気Ａ３を室内Ｒｉｎに導入する空調運転を実行する。そのために、空気調和機１０は、換気装置５０を有する。換気装置５０は、室外機３０に設けられている。すなわち、室外機３０は、換気装置５０を有する。 The air conditioner 10 performs an air-conditioning operation that introduces the outdoor air A3 into the room Rin in addition to the air-conditioning operation using the refrigeration cycle. Therefore, the air conditioner 10 has a ventilator 50 . A ventilation device 50 is provided in the outdoor unit 30 . That is, the outdoor unit 30 has a ventilator 50 .
　図２は、換気装置５０の構成を示す概略図である。 FIG. 2 is a schematic diagram showing the configuration of the ventilation device 50. FIG.
　図２に示すように、換気装置５０は、その内部に室外空気Ａ３、Ａ４が通過する吸収材５２を備える。 As shown in FIG. 2, the ventilator 50 includes an absorbent 52 through which outdoor air A3 and A4 pass.
　吸収材５２は、空気が通過可能な部材であって、通過する空気から水分を捕集するまたは通過する空気に水分を与える部材である。本実施の形態の場合、吸収材５２は、円盤状であって、その中心を通過する回転中心線Ｃ１を中心にして回転する。吸収材５２は、モータ５４によって回転駆動される。 The absorbent material 52 is a member through which air can pass, and is a member that collects moisture from the passing air or gives moisture to the passing air. In the case of this embodiment, the absorber 52 is disc-shaped and rotates around a rotation center line C1 passing through the center thereof. The absorbing material 52 is rotationally driven by a motor 54 .
　吸収材５２は、空気中の水分を収着する高分子収着材で形成されることが好ましい。高分子収着材は、例えば、ポリアクリル酸ナトリウム架橋体から構成される。高分子収着材は、シリカゲルやゼオライトなどの吸着材に比べて、同一体積あたりの水分吸収量が多く、低い加熱温度で担持する水分を脱着することができ、そして水分を長時間担持することができる。 The absorbent material 52 is preferably made of a polymer sorbent material that sorbs moisture in the air. The polymeric sorbent material is composed of, for example, a crosslinked sodium polyacrylate. Compared to adsorbents such as silica gel and zeolite, polymer sorbents absorb more water per unit volume, can desorb water at low heating temperatures, and can retain water for a long time. can be done.
　換気装置５０の内部には、吸収材５２をそれぞれ通過し、室外空気Ａ３、Ａ４がそれぞれ流れる第１の流路Ｐ１と第２の流路Ｐ２とが設けられている。第１の流路Ｐ１と第２の流路Ｐ２は、異なる位置で吸収材５２を通過する。 Inside the ventilator 50, there are provided a first flow path P1 and a second flow path P2 through which the outdoor air A3 and A4 respectively pass through the absorbent material 52. The first flow path P1 and the second flow path P2 pass through the absorbent material 52 at different positions.
　第１の流路Ｐ１は、室内機２０内に向かう室外空気Ａ３が流れる流路である。第１の流路Ｐ１を流れる室外空気Ａ３は、換気導管５６を介して、室内機２０内に供給される。 The first flow path P1 is a flow path through which the outdoor air A3 flows toward the inside of the indoor unit 20. The outdoor air A3 flowing through the first flow path P1 is supplied into the indoor unit 20 via the ventilation conduit 56. As shown in FIG.
　本実施の形態の場合、第１の流路Ｐ１は、吸収材５２に対して上流側に複数の支流路Ｐ１ａ、Ｐ１ｂを含んでいる。なお、本明細書において、「上流」および「下流」は、空気の流れに対して使用される。 In the case of the present embodiment, the first flow path P1 includes a plurality of branch flow paths P1a and P1b on the upstream side with respect to the absorbent 52. It should be noted that "upstream" and "downstream" are used herein with respect to air flow.
　複数の支流路Ｐ１ａ、Ｐ２ａは、吸収材５２に対して上流側で合流する。複数の支流路Ｐ１ａ、Ｐ１ｂそれぞれには、室外空気Ａ３を加熱する第１および第２のヒータ５８、６０が設けられている。 The plurality of tributaries P1a and P2a merge with the absorbent 52 on the upstream side. First and second heaters 58 and 60 for heating the outdoor air A3 are provided in the plurality of branch passages P1a and P1b, respectively.
　第１および第２のヒータ５８、６０は、同一の加熱能力を備えるヒータであってもよいし、異なる加熱能力を備えるヒータであってもよい。また、第１および第２のヒータ５８、６０は、電流が流れて温度が上昇すると電気抵抗が増加する、すなわち過剰な加熱温度の上昇を抑制することができるＰＴＣ（Ｐｏｓｉｔｉｖｅ　Ｔｅｍｐｅｒａｔｕｒｅ　Ｃｏｅｆｆｉｃｉｅｎｔ）ヒータが好ましい。ニクロム線やカーボン繊維などを用いるヒータを用いてもよいが、この場合、電流が流れ続けると加熱温度（表面温度）が上昇し続けるため、その温度をモニタリングする必要がある。一方、ＰＴＣヒータの場合、ヒータ自体が加熱温度を一定の温度範囲内で調節するために、加熱温度をモニタリングする必要がなくなる。この点で、ＰＴＣヒータがより好ましい。 The first and second heaters 58, 60 may be heaters with the same heating capacity, or may be heaters with different heating capacities. In addition, the first and second heaters 58 and 60 are preferably PTC (Positive Temperature Coefficient) heaters, which increase electrical resistance when current flows and the temperature rises, that is, can suppress excessive heating temperature rises. . A heater using a nichrome wire, carbon fiber, or the like may be used, but in this case, if the current continues to flow, the heating temperature (surface temperature) will continue to rise, so it is necessary to monitor the temperature. On the other hand, the PTC heater eliminates the need to monitor the heating temperature because the heater itself regulates the heating temperature within a certain temperature range. In this respect, the PTC heater is more preferable.
　第１の流路Ｐ１には、室内機２０内に向かう室外空気Ａ３の流れを発生させる第１のファン６２が設けられている。本実施の形態の場合、第１のファン６２は、吸収材５２に対して下流側に配置されている。第１のファン６２が作動することにより、室外空気Ａ３が、室外Ｒｏｕｔから第１の流路Ｐ１内に流入し、吸収材５２を通過する。 A first fan 62 that generates a flow of the outdoor air A3 toward the inside of the indoor unit 20 is provided in the first flow path P1. In the case of this embodiment, the first fan 62 is arranged downstream with respect to the absorbent 52 . By operating the first fan 62 , the outdoor air A 3 flows from the outdoor Rout into the first flow path P 1 and passes through the absorbent 52 .
　また、第１の流路Ｐ１には、第１の流路Ｐ１を流れる室外空気Ａ３を室内Ｒｉｎ（すなわち室内機２０）または室外Ｒｏｕｔに振り分けるダンパ装置６４が設けられている。本実施の形態の場合、ダンパ装置６４は、第１のファン６２に対して下流側に配置されている。ダンパ装置６４によって室内機２０に振り分けられた室外空気Ａ３は、換気導管５６を介して室内機２０内に入り、ファン２４によって室内Ｒｉｎに吹き出される。 Also, the first flow path P1 is provided with a damper device 64 that distributes the outdoor air A3 flowing through the first flow path P1 to the indoor Rin (that is, the indoor unit 20) or the outdoor Rout. In this embodiment, the damper device 64 is arranged downstream of the first fan 62 . The outdoor air A3 distributed to the indoor unit 20 by the damper device 64 enters the indoor unit 20 via the ventilation conduit 56 and is blown out by the fan 24 to the indoor unit Rin.
　第２の流路Ｐ２は、室外空気Ａ４が流れる流路である。第１の流路Ｐ１を流れる室外空気Ａ３と異なり、第２の流路Ｐ２を流れる室外空気Ａ４は、室内機２０に向かうことはない。第２の流路Ｐ２を流れる室外空気Ａ４は、吸収材５２を通過した後、室外Ｒｏｕｔに流出する。 The second flow path P2 is a flow path through which the outdoor air A4 flows. Unlike the outdoor air A3 flowing through the first flow path P1, the outdoor air A4 flowing through the second flow path P2 does not go to the indoor unit 20. The outdoor air A4 flowing through the second flow path P2 flows out to the outdoor Rout after passing through the absorbent 52 .
　第２の流路Ｐ２には、室外空気Ａ４の流れを発生させる第２のファン６６が設けられている。本実施の形態の場合、第２のファン６６は、吸収材５２に対して下流側に配置されている。第２のファン６６が作動することにより、室外空気Ａ４が、室外Ｒｏｕｔから第２の流路Ｐ２内に流入し、吸収材５２を通過し、そして室外Ｒｏｕｔに流出する。 A second fan 66 that generates a flow of outdoor air A4 is provided in the second flow path P2. In the case of this embodiment, the second fan 66 is arranged downstream with respect to the absorbent 52 . By operating the second fan 66, the outdoor air A4 flows from the outdoor Rout into the second flow path P2, passes through the absorbent 52, and then flows out to the outdoor Rout.
　換気装置５０は、吸収材５２（モータ５４）、第１のヒータ５８、第２のヒータ６０、第１のファン６２、ダンパ装置６４、および第２のファン６６を選択的に使用して換気運転、加湿運転、および除湿運転を選択的に実行する。 The ventilator 50 selectively uses an absorbent 52 (motor 54), a first heater 58, a second heater 60, a first fan 62, a damper device 64, and a second fan 66 for ventilation operation. , humidification operation, and dehumidification operation are selectively performed.
　図３は、換気運転中の換気装置５０の動作状態を示す概略図である。 FIG. 3 is a schematic diagram showing the operating state of the ventilator 50 during ventilation operation.
　換気運転は、室外空気Ａ３をそのまま換気導管５６を介して室内Ｒｉｎ（すなわち室内機２０）に供給する空調運転である。図３に示すように、換気運転中、モータ５４は、吸収材５２を回転し続ける。第１のヒータ５８と第２のヒータ６０は、ＯＦＦ状態であって、室外空気Ａ３を加熱していない。第１のファン６２はＯＮ状態で、それにより第１の流路Ｐ１内を室外空気Ａ３が流れている。ダンパ装置６４は、第１の流路Ｐ１内の室外空気Ａ３を室内機２０に振り分ける。第２のファン６６は、ＯＦＦ状態であって、それにより第２の流路Ｐ２内に室外空気Ａ４の流れが発生していない。 The ventilation operation is an air conditioning operation in which the outdoor air A3 is directly supplied to the indoor Rin (that is, the indoor unit 20) via the ventilation conduit 56. As shown in FIG. 3, motor 54 continues to rotate absorbent material 52 during ventilation operation. The first heater 58 and the second heater 60 are in the OFF state and do not heat the outdoor air A3. The first fan 62 is in the ON state, thereby causing the outdoor air A3 to flow through the first flow path P1. The damper device 64 distributes the outdoor air A3 in the first flow path P1 to the indoor units 20 . The second fan 66 is in an OFF state, so that no flow of outdoor air A4 is generated in the second flow path P2.
　このような換気運転によれば、室外空気Ａ３は、第１の流路Ｐ１に流入し、第１および第２のヒータ５８、６０に加熱されることなく吸収材５２を通過する。吸収材５２を通過した室外空気Ａ３は、ダンパ装置６４によって室内機２０に振り分けられる。ダンパ装置６４を通過して換気導管５６を介して室内機２０に到達した室外空気Ａ３は、ファン２４によって室内Ｒｉｎに吹き出される。このような換気運転により、室外空気Ａ３がそのまま室内Ｒｉｎに供給され、室内Ｒｉｎが換気される。 According to such a ventilation operation, the outdoor air A3 flows into the first flow path P1 and passes through the absorbent 52 without being heated by the first and second heaters 58, 60. The outdoor air A3 that has passed through the absorbent 52 is distributed to the indoor units 20 by the damper device 64 . The outdoor air A3 that has passed through the damper device 64 and reached the indoor unit 20 via the ventilation conduit 56 is blown out into the room Rin by the fan 24 . Through such a ventilation operation, the outdoor air A3 is supplied to the room Rin as it is, and the room Rin is ventilated.
　図４は、加湿運転中の換気装置５０の動作状態を示す概略図である。 FIG. 4 is a schematic diagram showing the operating state of the ventilator 50 during humidification operation.
　加湿運転は、室外空気Ａ３を加湿し、その加湿された室外空気Ａ３を室内Ｒｉｎ（すなわち室内機２０）に供給する空調運転である。図４に示すように、加湿運転中、モータ５４は、吸収材５２を回転し続ける。第１のヒータ５８と第２のヒータ６０は、ＯＮ状態であって、室外空気Ａ３を加熱している。第１のファン６２はＯＮ状態で、それにより第１の流路Ｐ１内を室外空気Ａ３が流れている。ダンパ装置６４は、第１の流路Ｐ１内の室外空気Ａ３を室内機２０に振り分ける。第２のファン６６は、ＯＮ状態であって、それにより第２の流路Ｐ２内を室外空気Ａ４が流れている。 The humidification operation is an air conditioning operation that humidifies the outdoor air A3 and supplies the humidified outdoor air A3 to the indoor Rin (that is, the indoor unit 20). As shown in FIG. 4, the motor 54 continues to rotate the absorbent 52 during the humidification operation. The first heater 58 and the second heater 60 are in the ON state and heat the outdoor air A3. The first fan 62 is in the ON state, thereby causing the outdoor air A3 to flow through the first flow path P1. The damper device 64 distributes the outdoor air A3 in the first flow path P1 to the indoor units 20 . The second fan 66 is in the ON state, thereby causing the outdoor air A4 to flow through the second flow path P2.
　このような加湿運転によれば、室外空気Ａ３は、第１の流路Ｐ１に流入し、第１および第２のヒータ５８、６０に加熱されて吸収材５２を通過する。このとき、加熱された室外空気Ａ３は、加熱されていない場合に比べて、吸収材５２からより多量の水分を奪うことができる。それにより、室外空気Ａ３が多量の水分を担持する。吸収材５２を通過して多量の水分を担持する室外空気Ａ３は、ダンパ装置６４によって室内機２０に振り分けられる。ダンパ装置６４を通過して換気導管５６を介して室内機２０に到達した室外空気Ａ３は、ファン２４によって室内Ｒｉｎに吹き出される。このような加湿運転により、多量の水分を担持する室外空気Ａ３が室内Ｒｉｎに供給され、室内Ｒｉｎが加湿される。 According to such humidification operation, the outdoor air A3 flows into the first flow path P1, is heated by the first and second heaters 58 and 60, and passes through the absorbent 52. At this time, the heated outdoor air A3 can deprive the absorbent 52 of a larger amount of moisture than when it is not heated. As a result, the outdoor air A3 carries a large amount of moisture. The outdoor air A3 that has passed through the absorbent 52 and carries a large amount of moisture is distributed to the indoor unit 20 by the damper device 64 . The outdoor air A3 that has passed through the damper device 64 and reached the indoor unit 20 via the ventilation conduit 56 is blown out into the room Rin by the fan 24 . Through such a humidification operation, the outdoor air A3 carrying a large amount of moisture is supplied to the room Rin, and the room Rin is humidified.
　なお、第１のヒータ５８と第２のヒータ６０のいずれか一方をＯＦＦ状態にすることによって室外空気Ａ３が吸収材５２から奪う水分量を少なくする、すなわち室内Ｒｉｎの加湿量が少ない弱加湿運転が実行されてもよい。 By turning off either one of the first heater 58 and the second heater 60, the amount of moisture taken from the absorbent 52 by the outdoor air A3 is reduced. may be performed.
　加熱された室外空気Ａ３に水分が奪われることにより、吸収材５２の保水量が減少する、すなわち吸収材５２が乾燥する。吸収材５２が乾燥すると、第１の流路Ｐ１を流れる室外空気Ａ３は吸収材５２から水分を奪うことができない。その対処として、吸収材５２は、第２の流路Ｐ２を流れる室外空気Ａ４から水分を奪う。それにより、吸収材５２の保水量がほぼ一定に維持され、加湿運転を継続することができる。 As the heated outdoor air A3 deprives moisture, the amount of water retained by the absorbent 52 decreases, that is, the absorbent 52 dries. When the absorbent 52 dries, the outdoor air A3 flowing through the first flow path P1 cannot deprive the absorbent 52 of moisture. As a countermeasure, the absorbent 52 deprives the outdoor air A4 flowing through the second flow path P2 of water. As a result, the amount of water retained in the absorbent material 52 is kept substantially constant, and the humidification operation can be continued.
　図５は、除湿運転中の換気装置５０の動作状態を示す概略図である。 FIG. 5 is a schematic diagram showing the operating state of the ventilation device 50 during dehumidification operation.
　除湿運転は、室外空気Ａ３を除湿し、その除湿された室外空気Ａ３を室内Ｒｉｎ（すなわち室内機２０）に供給する空調運転である。図５に示すように、除湿運転では、吸着運転と再生運転とが交互に実行される。 The dehumidification operation is an air conditioning operation in which the outdoor air A3 is dehumidified and the dehumidified outdoor air A3 is supplied to the indoor Rin (that is, the indoor unit 20). As shown in FIG. 5, in the dehumidifying operation, the adsorption operation and the regeneration operation are alternately performed.
　吸着運転は、室外空気Ａ３に担持されている水分を吸収材５２に吸着させ、それにより室外空気Ａ３を除湿する運転である。図５に示すように、吸着運転中、モータ５４は、吸収材５２を回転し続ける。第１のヒータ５８と第２のヒータ６０は、ＯＦＦ状態であって、室外空気Ａ３を加熱していない。第１のファン６２はＯＮ状態で、それにより第１の流路Ｐ１内を室外空気Ａ３が流れている。ダンパ装置６４は、第１の流路Ｐ１内の室外空気Ａ３を室内機２０に振り分ける。第２のファン６６は、ＯＦＦ状態であって、それにより第２の流路Ｐ２内に室外空気Ａ４の流れが発生していない。 The adsorption operation is an operation in which the moisture carried in the outdoor air A3 is adsorbed by the absorbent material 52, thereby dehumidifying the outdoor air A3. As shown in FIG. 5, the motor 54 continues to rotate the absorbent 52 during the adsorption operation. The first heater 58 and the second heater 60 are in the OFF state and do not heat the outdoor air A3. The first fan 62 is in the ON state, thereby causing the outdoor air A3 to flow through the first flow path P1. The damper device 64 distributes the outdoor air A3 in the first flow path P1 to the indoor units 20 . The second fan 66 is in an OFF state, so that no flow of outdoor air A4 is generated in the second flow path P2.
　このような吸着運転によれば、室外空気Ａ３は、第１の流路Ｐ１に流入し、第１および第２のヒータ５８、６０に加熱されることなく吸収材５２を通過する。このとき、室外空気Ａ３に担持されている水分が吸収材５２に吸着する。それにより、室外空気Ａ３の水分の担持量が減少する、すなわち室外空気Ａ３が乾燥される。吸収材５２を通過して乾燥した室外空気Ａ３は、ダンパ装置６４によって室内機２０に振り分けられる。ダンパ装置６４を通過して換気導管５６を介して室内機２０に到達した室外空気Ａ３は、ファン２４によって室内Ｒｉｎに吹き出される。このような吸着運転により、乾燥した室外空気Ａ３が室内Ｒｉｎに供給され、室内Ｒｉｎが除湿される。 According to such adsorption operation, the outdoor air A3 flows into the first flow path P1 and passes through the absorbent 52 without being heated by the first and second heaters 58, 60. At this time, the moisture carried in the outdoor air A3 is absorbed by the absorbent 52 . As a result, the amount of moisture carried by the outdoor air A3 is reduced, that is, the outdoor air A3 is dried. The outdoor air A3 dried by passing through the absorbent 52 is distributed to the indoor unit 20 by the damper device 64 . The outdoor air A3 that has passed through the damper device 64 and reached the indoor unit 20 via the ventilation conduit 56 is blown out into the room Rin by the fan 24 . By such adsorption operation, the dry outdoor air A3 is supplied to the room Rin, and the room Rin is dehumidified.
　吸着運転が続くと、吸収材５２の保水量が増加し続け、その結果、室外空気Ａ３に担持されている水分に対する吸収材５２の吸着能力が低下する。その吸着能力を回復するために吸収材５２を再生させる再生運転が実行される。 As the adsorption operation continues, the water retention capacity of the absorbent 52 continues to increase, and as a result, the ability of the absorbent 52 to adsorb moisture carried in the outdoor air A3 decreases. A regeneration operation is performed to regenerate the absorbent 52 in order to recover its adsorption capacity.
　再生運転中、モータ５４は、吸収材５２を回転し続ける。第１のヒータ５８と第２のヒータ６０は、ＯＮ状態であって、室外空気Ａ３を加熱している。第１のファン６２はＯＮ状態で、それにより第１の流路Ｐ１内を室外空気Ａ３が流れている。ダンパ装置６４は、第１の流路Ｐ１内の室外空気Ａ３を、室内機２０ではなく、室外Ｒｏｕｔに振り分ける。第２のファン６６は、ＯＦＦ状態であって、それにより第２の流路Ｐ２内に室外空気Ａ４の流れが発生していない。 The motor 54 continues to rotate the absorbent 52 during the regeneration operation. The first heater 58 and the second heater 60 are in the ON state and heat the outdoor air A3. The first fan 62 is in the ON state, thereby causing the outdoor air A3 to flow through the first flow path P1. The damper device 64 distributes the outdoor air A3 in the first flow path P1 not to the indoor unit 20 but to the outdoor Rout. The second fan 66 is in an OFF state, so that no flow of outdoor air A4 is generated in the second flow path P2.
　このような再生運転によれば、室外空気Ａ３は、第１の流路Ｐ１に流入し、第１および第２のヒータ５８、６０に加熱されて吸収材５２を通過する。このとき、加熱された室外空気Ａ３は、吸収材５２から多量の水分を奪う。それにより、室外空気Ａ３に多量の水分が担持される。それとともに、吸収材５２の保水量が減少する、すなわち吸収材５２が乾燥してその吸着能力が再生する。吸収材５２を通過して多量の水分を担持する室外空気Ａ３は、ダンパ装置６４によって室外Ｒｏｕｔに振り分けられ、室外Ｒｏｕｔに排出される。これにより、除湿運転における再生運転中に、吸収材５２の再生によって多量の水分を担持する室外空気Ａ３が室内Ｒｉｎに供給されることがない。 According to such a regeneration operation, the outdoor air A3 flows into the first flow path P1, is heated by the first and second heaters 58 and 60, and passes through the absorbent 52. At this time, the heated outdoor air A3 deprives the absorbent 52 of a large amount of moisture. As a result, a large amount of moisture is carried in the outdoor air A3. At the same time, the water retention capacity of the absorbent 52 decreases, ie, the absorbent 52 dries and its adsorption capacity is regenerated. The outdoor air A3 that passes through the absorbent 52 and carries a large amount of moisture is distributed to the outdoor route by the damper device 64 and is discharged to the outdoor route. As a result, during the regeneration operation in the dehumidification operation, the outdoor air A3 carrying a large amount of moisture due to the regeneration of the absorbent 52 is not supplied to the indoor Rin.
　このような吸着運転と再生運転を交互に行うことにより、吸収材５２の吸着能力が維持され、除湿運転を継続的に実行することができる。 By alternately performing such adsorption operation and regeneration operation, the adsorption capacity of the absorbent 52 is maintained, and the dehumidification operation can be continuously performed.
　上述の冷凍サイクルによる空調運転（冷房運転、除湿運転（弱冷房運転）、暖房運転）と換気装置５０による空調運転（換気運転、加湿運転、除湿運転）は、別々に実行可能であり、また同時に実行することも可能である。例えば、冷凍サイクルによる除湿運転と換気装置５０による除湿運転を同時に実行すれば、室温を一定に維持した状態で室内Ｒｉｎを除湿することが可能である。 The air-conditioning operation (cooling operation, dehumidifying operation (weak cooling operation), heating operation) by the above-described refrigeration cycle and the air-conditioning operation (ventilation operation, humidification operation, dehumidification operation) by the ventilation device 50 can be performed separately, and at the same time It is also possible to execute For example, if the dehumidification operation by the refrigeration cycle and the dehumidification operation by the ventilation device 50 are simultaneously executed, it is possible to dehumidify the room Rin while maintaining the room temperature constant.
　空気調和機１０が実行する空調運転は、ユーザによって選択される。例えば、図１に示すリモートコントローラ７０に対するユーザの選択操作により、その操作に対応する空調運転を空気調和機１０は実行する。なお、空気調和機１０は、冷凍サイクルによる空調運転および換気装置５０による空調運転の実行を制御する制御装置（図示せず）を備える。制御装置は、プロセッサおよびメモリを有するコンピュータシステムを有している。そして、プロセッサがメモリに格納されているプログラムを実行することにより、コンピュータシステムが制御装置として機能する。プロセッサが実行するプログラムは、ここではコンピュータシステムのメモリに予め記録されているとしたが、メモリカード等の非一時的な記録媒体に記録されて提供されてもよいし、インターネット等の電気通信回線を通じて提供されてもよい。 The air conditioning operation performed by the air conditioner 10 is selected by the user. For example, when a user selects the remote controller 70 shown in FIG. 1, the air conditioner 10 performs the air conditioning operation corresponding to the operation. Note that the air conditioner 10 includes a control device (not shown) that controls execution of the air conditioning operation by the refrigeration cycle and the air conditioning operation by the ventilation device 50 . The controller has a computer system with a processor and memory. The computer system functions as a control device by the processor executing the program stored in the memory. Although the program executed by the processor is recorded in advance in the memory of the computer system here, it may be recorded in a non-temporary recording medium such as a memory card and provided, or may be provided through a telecommunication line such as the Internet. may be provided through

　また、本実施の形態の場合、図１４に示すように、ヒータベース部材１１２のヒータ載置部１１２ａの下部には、アンダーカバー部材１２２が取り付けられている。アンダーカバー部材１２２は、ヒータ載置部１１２ａに取り付けられる底板部１２２ａと、高さ方向（Ｚ軸方向）に底板部１２２ａから延在する壁部１２２ｂとを備える。壁部１２２ｂは、第１のヒータ５８および第２のヒータ６０と第２のカバー部材１２０の壁部１２０ｂとの間で延在している。 Further, in the case of the present embodiment, as shown in FIG. 14, an undercover member 122 is attached to the lower portion of the heater mounting portion 112a of the heater base member 112. As shown in FIG. The undercover member 122 includes a bottom plate portion 122a attached to the heater mounting portion 112a and a wall portion 122b extending from the bottom plate portion 122a in the height direction (Z-axis direction). Wall portion 122 b extends between first heater 58 and second heater 60 and wall portion 120 b of second cover member 120 .
　このような第２のカバー部材１２０およびアンダーカバー部材１２２によれば、室外空気Ａ３は、第２のカバー部材１２０の壁部１２０ｂとアンダーカバー部材１２２の壁部１２２ｂとの間の隙間を上方向に向かって流れる。次に、室外空気Ａ３は、アンダーカバー部材１２２の壁部１２２ｂを乗り越えて底板部１２２ａの上方を水平方向（Ｘ軸方向）に流れ、そして、第１のヒータ５８と第２のヒータ６０とに到達する。このような室外空気Ａ３の流れ（すなわち支流路Ｐ１ａ、Ｐ１ｂ）により、室外空気Ａ３が第１のヒータ５８および第２のヒータ６０に到達する前に、室外空気Ａ３に同伴するほこりなど異物が、重力によって取り除かれる。なお、第２のカバー部材１２０の壁部１２０ｂとアンダーカバー部材１２２の壁部１２２ｂとの間の隙間の距離Ｄは、昆虫などの生物が進入できないサイズ、例えば８ｍｍ以下にされている。これにより、第１のヒータ５８と第２のヒータ６０への生物の侵入が抑制されている。 According to the second cover member 120 and the undercover member 122, the outdoor air A3 flows upward through the gap between the wall portion 120b of the second cover member 120 and the wall portion 122b of the undercover member 122. flowing towards Next, the outdoor air A3 climbs over the wall portion 122b of the undercover member 122 and flows above the bottom plate portion 122a in the horizontal direction (X-axis direction). reach. Before the outdoor air A3 reaches the first heater 58 and the second heater 60, foreign matter such as dust entrained in the outdoor air A3 is removed by gravity. The distance D of the gap between the wall portion 120b of the second cover member 120 and the wall portion 122b of the undercover member 122 is set to a size, for example, 8 mm or less, which prevents insects and other organisms from entering. As a result, invasion of organisms into the first heater 58 and the second heater 60 is suppressed.
　図１４に示すように、第１のカバー部材１１８と第２のカバー部材１２０の天板部１２０ａとの間の隙間には、室外空気Ａ３が流れる。すなわち、第１のカバー部材１１８と第２のカバー部材１２０との間の隙間が、支流路Ｐ１ａにおける第１のヒータ５８に対する上流側部分と支流路Ｐ１ｂにおける第２のヒータ６０に対する上流側部分とを連絡する連絡路Ｐ１ｄとして機能する。本実施の形態の場合、第１のヒータ５８から第１のファン６２までの流路長が、第２のヒータ６０から第１のファン６２までの流路長より短い。そのため、第１のヒータ５８での室外空気Ａ３の流速が、第２のヒータ６０での流速に比べて高速である。その結果、図１４に示すように、第２のヒータ６０に対して上流側の支流路Ｐ１ｂの部分を流れる室外空気Ａ３の一部が、連絡路Ｐ１ｄを流れて支流路Ｐ１ａに流入し、そして第１のヒータ５８を通過する。 As shown in FIG. 14, the outdoor air A3 flows through the gap between the first cover member 118 and the top plate portion 120a of the second cover member 120. As shown in FIG. That is, the gap between the first cover member 118 and the second cover member 120 is divided into the upstream portion of the branch passage P1a with respect to the first heater 58 and the upstream portion of the branch passage P1b with respect to the second heater 60. It functions as a connecting path P1d that connects the In the case of this embodiment, the channel length from the first heater 58 to the first fan 62 is shorter than the channel length from the second heater 60 to the first fan 62 . Therefore, the flow velocity of the outdoor air A3 at the first heater 58 is higher than the flow velocity at the second heater 60 . As a result, as shown in FIG. 14, part of the outdoor air A3 flowing through the upstream branch passage P1b with respect to the second heater 60 flows through the connecting passage P1d and into the branch passage P1a. It passes through the first heater 58 .
　このような連絡路Ｐ１ｄを設ける理由は、第１のヒータ５８および第２のヒータ６０の排熱Ｈを有効利用するためである。具体的には、第１のヒータ５８および第２のヒータ６０が発生する熱の多くは、これらを通過する室外空気Ａ３の加熱に使用される。しかしながら、発生した熱の一部は、第１のヒータ５８および第２のヒータ６０を通過する室外空気Ａ３に伝達することなく、第１のヒータ５８および第２のヒータ６０の周囲に伝達する、特に第１のヒータ５８と第２のヒータ６０の上方に伝達する。 The reason for providing such a communication path P1d is to effectively utilize the exhaust heat H of the first heater 58 and the second heater 60. Specifically, much of the heat generated by first heater 58 and second heater 60 is used to heat outdoor air A3 passing through them. However, part of the generated heat is transmitted around the first heater 58 and the second heater 60 without being transmitted to the outdoor air A3 passing through the first heater 58 and the second heater 60. Specifically, it propagates above the first heater 58 and the second heater 60 .
　本実施の形態の場合、第１のヒータ５８と第２のヒータ６０の排熱Ｈは、連絡路Ｐ１ｄを流れる室外空気Ａ３に伝達する。その排熱Ｈによって加熱された室外空気Ａ３は、第１のヒータ５８または第２のヒータ６０を通過し、そして吸収材５２を通過する。このように、連絡路Ｐ１ｄを流れる室外空気Ａ３が第１のヒータ５８と第２のヒータ６０の排熱Ｈを回収することにより、第１および第２のヒータ５８、６０による室外空気Ａ３の加熱効率が向上する。その結果、室外空気Ａ３の加湿量（吸収材５２から奪う水分量）が増加し、加湿運転の効率（室内Ｒｉｎの加湿効率）または除湿運転における再生運転の効率（吸収材５２の再生効率）が向上する。 In the case of the present embodiment, exhaust heat H from the first heater 58 and the second heater 60 is transferred to the outdoor air A3 flowing through the communication path P1d. The outdoor air A3 heated by the exhaust heat H passes through the first heater 58 or the second heater 60 and then through the absorbent 52 . In this manner, the outdoor air A3 flowing through the communication path P1d recovers the exhaust heat H of the first heater 58 and the second heater 60, whereby the outdoor air A3 is heated by the first and second heaters 58 and 60. Improve efficiency. As a result, the amount of humidification of the outdoor air A3 (the amount of moisture taken from the absorbent 52) increases, and the efficiency of the humidification operation (humidification efficiency of the indoor Rin) or the efficiency of the regeneration operation in the dehumidification operation (the regeneration efficiency of the absorbent 52) increases. improves.
　なお、このような排熱回収用の連絡路Ｐ１ｄは、第１のヒータ５８および第２のヒータ６０の上方に限らず、下方にも設けてもよい。連絡路Ｐ１ｄは、第１のヒータ５８および第２のヒータ６０近傍、すなわち第１のヒータ５８および第２のヒータ６０の排熱Ｈが伝達する領域を通過すればよい。 It should be noted that such a communication path P1d for exhaust heat recovery may be provided not only above the first heater 58 and the second heater 60, but also below them. The communication path P1d may pass through the vicinity of the first heater 58 and the second heater 60, that is, the area where the exhaust heat H of the first heater 58 and the second heater 60 is transmitted.
　第１のヒータ５８および第２のヒータ６０の少なくとも一方によって加熱された室外空気Ａ３は、図１０に示すように、吸収材５２を第１の端面５２ａから第２の端面５２ｂに向かって下方向に通過し、第２の空間Ｓ２に入る。 The outdoor air A3 heated by at least one of the first heater 58 and the second heater 60 moves the absorbent 52 downward from the first end surface 52a toward the second end surface 52b as shown in FIG. and enter the second space S2.
　図１５は、第２の空間Ｓ２を示す換気装置５０の筺体１０２の一部分の周辺の構成を示す上面図である。 FIG. 15 is a top view showing a configuration around a portion of the housing 102 of the ventilation device 50 showing the second space S2.
　図１５に示すように、筺体１０２の底板１０２ｆには、高さ方向（Ｚ軸方向）に延在する環状壁部１０２ｋが形成されている。この環状壁部１０２ｋの頂部に、第１の空間Ｓ１と第２の空間Ｓ２とを隔てる仕切り板１２４が配置される（図１０参照）。これらの筺体１０２の環状壁部１０２ｋと仕切り板１２４とにより、第２の空間Ｓ２が画定されている。なお、吸収材５２の下方に位置する環状壁部１０２ｋの部分１０２ｌ上には、環状壁部１０２ｋと吸収材５２との間をシールする、後述するシールユニットが取り付けられる。 As shown in FIG. 15, the bottom plate 102f of the housing 102 is formed with an annular wall portion 102k extending in the height direction (Z-axis direction). A partition plate 124 separating the first space S1 and the second space S2 is arranged at the top of the annular wall portion 102k (see FIG. 10). The annular wall portion 102k of the housing 102 and the partition plate 124 define a second space S2. A sealing unit (described later) for sealing between the annular wall portion 102k and the absorbing material 52 is mounted on the portion 102l of the annular wall portion 102k located below the absorbing material 52.

　図１６に示すように、吸収材５２の第１の端面５２ａに対する複数の第１のシールユニット１２６と、吸収材５２の第２の端面５２ｂに対する複数の第２のシールユニット１２８が、換気装置５０に設けられている。本実施の形態の場合、第１のシールユニット１２６は、吸収材５２の第１の端面５２ａに対向するヒータベース部材１１２の複数のビーム部１１２ｄに設けられている。第２のシールユニット１２８は、吸収材５２の第２の端面５２ｂに対向する筺体１０２の環状壁部１０２ｋの部分１０２ｌに設けられている。 As shown in FIG. 16, a plurality of first sealing units 126 against the first end face 52a of the absorbent material 52 and a plurality of second sealing units 128 against the second end face 52b of the absorbent material 52 are connected to the ventilator 50. is provided in In the case of this embodiment, the first seal unit 126 is provided on a plurality of beam portions 112 d of the heater base member 112 facing the first end face 52 a of the absorbent 52 . The second seal unit 128 is provided on the portion 102 l of the annular wall portion 102 k of the housing 102 facing the second end face 52 b of the absorbent 52 .
　複数の第１のシールユニット１２６は、吸収材５２の第１の端面５２ａに高さ方向（Ｚ軸方向）に接触するシール部材１２６ａと、シール部材１２６ａを保持してヒータベース部材１１２に取り付けられるシールホルダ１２６ｂとを備える。シール部材１２６ａは、円盤状の吸収材５２の径方向に実質的に延在し、吸収材５２の第１の端面５２ａに接触する。本実施の形態の場合、シール部材１２６ａは、ブラシである。なお、シール部材１２６ａは、回転する吸収材５２の第１の端面５２ａに対して摺動可能であれば、ブラシに限らない。シール部材１２６ａは、例えば、可撓性を備えるシリコンゴムなどの弾性部材であってもよい。 The plurality of first seal units 126 are attached to the heater base member 112 while holding the seal member 126a contacting the first end face 52a of the absorbent 52 in the height direction (Z-axis direction) and the seal member 126a. and a seal holder 126b. The seal member 126a substantially extends in the radial direction of the disk-shaped absorbent 52 and contacts the first end face 52a of the absorbent 52 . In this embodiment, the sealing member 126a is a brush. Note that the sealing member 126a is not limited to a brush as long as it can slide against the first end surface 52a of the rotating absorbent 52 . The seal member 126a may be, for example, an elastic member such as silicone rubber having flexibility.
　このような第１のシールユニット１２６により、第１の流路Ｐ１を流れる室外空気Ａ３、具体的には第１のカバー部材１１８内を流れる室外空気Ａ３の一部が、第２の流路Ｐ２（すなわち第４の空間Ｓ４）内に侵入することが抑制される。また、それとは逆に、第２の流路Ｐ２内を流れる室外空気Ａ４が第１の流路Ｐ１内に侵入することも抑制される。 With such a first seal unit 126, the outdoor air A3 flowing through the first flow path P1, specifically, a part of the outdoor air A3 flowing inside the first cover member 118 is transferred to the second flow path P2. (that is, entering the fourth space S4) is suppressed. Conversely, the outdoor air A4 flowing through the second flow path P2 is also suppressed from entering the first flow path P1.
　複数の第２のシールユニット１２８は、吸収材５２の第２の端面５２ｂに高さ方向（Ｚ軸方向）に接触するシール部材１２８ａと、シール部材１２８ａを保持して筺体１０２に取り付けられるシールホルダ１２８ｂとを備える。シール部材１２８ａは、円盤状の吸収材５２の径方向に実質的に延在するとともに、第１のシールユニット１２６のシール部材１２６ａに対して平行に延在し、吸収材５２の第２の端面５２ｂに接触する。本実施の形態の場合、シール部材１２８ａは、ブラシである。なお、シール部材１２８ａは、回転する吸収材５２の第２の端面５２ｂに対して摺動可能であれば、ブラシに限らない。シール部材１２８ａは、例えば、可撓性を備えるシリコンゴムなどの弾性部材であってもよい。また、シール部材１２８ａは、第１のシールユニット１２６のシール部材１２６ａと異なってもよく、また同一であってもよい。 The plurality of second seal units 128 includes a seal member 128a that contacts the second end face 52b of the absorbent 52 in the height direction (Z-axis direction), and a seal holder that holds the seal member 128a and is attached to the housing 102. 128b. The seal member 128a extends substantially in the radial direction of the disk-shaped absorber 52, extends parallel to the seal member 126a of the first seal unit 126, and extends along the second end face of the absorber 52. 52b. In this embodiment, the sealing member 128a is a brush. Note that the sealing member 128a is not limited to a brush as long as it can slide against the second end surface 52b of the rotating absorbent 52 . The sealing member 128a may be, for example, an elastic member such as silicone rubber having flexibility. Also, the seal member 128a may be different from the seal member 126a of the first seal unit 126, or may be the same.
　このような第２のシールユニット１２８により、第１の流路Ｐ１を流れる室外空気Ａ３、具体的には吸収材５２の第２の端面５２ｂから第２の空間Ｓ２に流入する室外空気Ａ３の一部が、第２の流路Ｐ２（すなわち第３の空間Ｓ３）内に侵入することが抑制される。また、それとは逆に、第２の流路Ｐ２内を流れる室外空気Ａ４が第１の流路Ｐ１内に侵入することも抑制される。 With such a second seal unit 128, part of the outdoor air A3 flowing through the first flow path P1, specifically, the outdoor air A3 flowing into the second space S2 from the second end surface 52b of the absorbent 52 is is suppressed from entering the second flow path P2 (that is, the third space S3). Conversely, the outdoor air A4 flowing through the second flow path P2 is also suppressed from entering the first flow path P1.
　なお、本実施の形態の場合、図１２に示すように、第２のシールユニット１２８（そのシール部材１２８ａ）が接触する吸収材５２の第２の端面５２ｂ上には、吸収材ホルダ１１４の複数のスポーク部１１４ｃが存在する。そのため、吸収材ホルダ１１４の回転中、シール部材１２８ａは、複数のスポーク部１１４ｃを乗り越える必要がある。 In this embodiment, as shown in FIG. 12, a plurality of absorbent holders 114 are provided on the second end face 52b of the absorbent 52 with which the second seal unit 128 (the seal member 128a thereof) contacts. There is a spoke portion 114c of . Therefore, during rotation of the absorbent holder 114, the seal member 128a needs to climb over the plurality of spoke portions 114c.
　このとき、シール部材１２８ａ全体が同時のタイミングでスポーク部１１４ｃを乗り越えると、そのタイミングに吸収材ホルダ１１４の回転抵抗が増加する。その結果、吸収材ホルダ１１４を回転させるモータ５４に断続的にトルク負荷がかかる。 At this time, when the entire sealing member 128a gets over the spoke portion 114c at the same timing, the rotational resistance of the absorbent holder 114 increases at that timing. As a result, an intermittent torque load is applied to the motor 54 that rotates the absorbent holder 114 .
　そこで、シール部材１２８ａ全体が同時のタイミングでスポーク部１１４ｃを乗り越えないように、スポーク部１１４ｃが延在している。具体的には、シール部材１２８ａは吸収材５２の径方向に実質的に延在し、スポーク部１１４ｃは吸収材５２の径方向に実質的に延在していない。その結果、例えばシール部材１２８ａの吸収材５２の中心側の端がスポーク部１１４ｃ上に位置するとき、シール部材１２８ａの外側の端はスポーク部１１４ｃ上に位置していない。このような延在方向の違いにより、シール部材１２８ａは、その全体がスポーク部１１４ｃを同時に乗り越えることなく、一部分ずつスポーク部１１４ｃを乗り越える。その結果、モータ５４への負荷が低減される。 Therefore, the spoke portion 114c is extended so that the entire sealing member 128a does not get over the spoke portion 114c at the same timing. Specifically, the sealing member 128 a substantially extends in the radial direction of the absorbent 52 , and the spoke portion 114 c does not substantially extend in the radial direction of the absorbent 52 . As a result, for example, when the center side end of the sealing member 128a of the absorbent 52 is positioned on the spoke portion 114c, the outer end of the sealing member 128a is not positioned on the spoke portion 114c. Due to such a difference in extending direction, the seal member 128a does not ride over the spoke portions 114c as a whole, but partially rides over the spoke portions 114c. As a result, the load on the motor 54 is reduced.
　また、図１６に示すように、第１のシールユニット１２６が設けられるヒータベース部材１１２のビーム部１１２ｄには、第１のシールユニット１２６から離れる方向に延在する衝突板１１２ｅが設けられている。衝突板１１２ｅは、室外空気Ａ４が流出する吸収材５２の第１の端面５２ａの部分の上方を延在する。その結果、衝突板１１２ｅには、第１のシールユニット１２６近傍で吸収材５２を通過した室外空気Ａ４が衝突する。この「衝突板」について比較例を挙げて説明する。 Further, as shown in FIG. 16, the beam portion 112d of the heater base member 112 provided with the first seal unit 126 is provided with a collision plate 112e extending in a direction away from the first seal unit 126. . The collision plate 112e extends above the portion of the first end surface 52a of the absorbent 52 through which the outdoor air A4 flows. As a result, the outdoor air A4 that has passed through the absorbing material 52 near the first seal unit 126 collides with the collision plate 112e. This "collision plate" will be described with reference to a comparative example.
　図１７は、比較例の換気装置における、吸収材５２の径方向と直交する吸収材５２の一部分の周辺の構成を示す概略的な断面図である。 FIG. 17 is a schematic cross-sectional view showing the configuration around a portion of the absorbent 52 orthogonal to the radial direction of the absorbent 52 in the ventilator of the comparative example.
　図１７に示すように、比較例の換気装置では、第１のシールユニット１２６から離れるように第２の流路Ｐ２内に突出する衝突板１１２ｅがない。この場合、第１のヒータ５８および第２のヒータ６０を通過して吸収材５２内に流入する前の室外空気Ａ３の一部が、第２の流路Ｐ２内に侵入しうる。具体的には、室外空気Ａ３の一部が、シール部材１２６ａと吸収材５２との間を通過して第２の流路Ｐ２内に侵入しうる。 As shown in FIG. 17, in the ventilator of the comparative example, there is no impingement plate 112e protruding into the second flow path P2 away from the first seal unit 126. As shown in FIG. In this case, part of the outdoor air A3 before passing through the first heater 58 and the second heater 60 and flowing into the absorbent 52 may enter the second flow path P2. Specifically, part of the outdoor air A3 may pass between the seal member 126a and the absorbent 52 and enter the second flow path P2.
　この室外空気Ａ３のシール部材１２６ａと吸収材５２との間の通過は、吸収材５２の通風抵抗、すなわち吸収材５２を通過することによって生じる圧力損失を原因として起こる。具体的には、吸収材５２に対して上流側の第１の流路Ｐ１の部分（すなわち空間Ｓ５）内の圧力は、吸収材５２によって圧力損失が起こる前の圧力である。これに対して、吸収材５２に対して下流側の第２の流路Ｐ２の部分（すなわち第４の空間Ｓ４）内の圧力は、吸収材５２を通過して圧力損失が生じた後の圧力である。すなわち、空間Ｓ５の圧力は、吸収材５２を通過していない分、空間Ｓ４内の圧力に比べて相対的に高い。この２つの圧力の差により、室外空気Ａ３のシール部材１２６ａと吸収材５２との間の通過が起こりうる。その結果、相対的に高圧で第１のヒータ５８および第２のヒータ６０によって加熱された室外空気Ａ３が、シール部材１２６ａと吸収材５２との間を介して、相対的に低圧の第２の流路Ｐ２内に侵入しうる。 The passage of the outdoor air A3 between the sealing member 126a and the absorbent 52 is caused by the draft resistance of the absorbent 52, that is, the pressure loss caused by passing through the absorbent 52. Specifically, the pressure in the portion of the first flow path P<b>1 on the upstream side of the absorbent 52 (that is, the space S<b>5 ) is the pressure before pressure loss occurs due to the absorbent 52 . On the other hand, the pressure in the portion of the second flow path P2 on the downstream side of the absorbent 52 (that is, the fourth space S4) is the pressure after passing through the absorbent 52 and causing pressure loss. is. That is, the pressure in the space S5 is relatively higher than the pressure in the space S4 because it does not pass through the absorbent 52 . The difference between the two pressures can cause outdoor air A3 to pass between the seal member 126a and the absorbent material 52 . As a result, the outdoor air A3 heated by the first heater 58 and the second heater 60 at a relatively high pressure passes between the seal member 126a and the absorbent 52 and flows through the second heater at a relatively low pressure. It can intrude into the flow path P2.
　このように加熱されて高温の室外空気Ａ３の一部が吸収材５２を通過せずに第２の流路Ｐ２内に侵入すると、室外空気Ａ３が吸収材５２から奪う水分量が減少する。すなわち加湿運転の効率（室内Ｒｉｎの加湿効率）が低下する。この対処として、本実施の形態の場合、図１６に示すように、第１のシールユニット１２６から第２の流路Ｐ２内に突出する衝突板１１２ｅが存在する。 When part of the heated outdoor air A3 of high temperature enters the second flow path P2 without passing through the absorbent 52, the amount of moisture taken from the absorbent 52 by the outdoor air A3 decreases. That is, the efficiency of the humidification operation (humidification efficiency of the room Rin) decreases. As a countermeasure for this, in the case of the present embodiment, as shown in FIG. 16, there is a collision plate 112e that protrudes from the first seal unit 126 into the second flow path P2.
　図１６に示すように、第１のシールユニット１２６近傍を流れる室外空気Ａ４は、吸収材５２の第１の端面５２ａから流出した後、衝突板１１２ｅに衝突する。それにより、吸収材５２の第１の端面５２ａと衝突板１１２ｅとの間に乱流状態の高圧領域ＡＰが発生する。この高圧領域ＡＰにより、シール部材１２６ａの両側の圧力差が小さくなる。その結果、シール部材１２６ａと吸収材５２との間を介する室外空気Ａ３の第２の流路Ｐ２への侵入が抑制される。 As shown in FIG. 16, the outdoor air A4 flowing near the first seal unit 126 flows out from the first end face 52a of the absorbent 52 and then collides with the collision plate 112e. As a result, a turbulent high pressure region AP is generated between the first end face 52a of the absorber 52 and the collision plate 112e. This high pressure area AP reduces the pressure difference between both sides of the seal member 126a. As a result, entry of the outdoor air A3 into the second flow path P2 through between the seal member 126a and the absorbent 52 is suppressed.
　本実施の形態の場合、衝突板１１２ｅの先端（第１のシールユニット１２６から遠い端）には、吸収材５２の第１の端面５２ａに向かって延在する絞り壁１１２ｆが設けられている。これにより、シール部材１２６ａ、衝突板１１２ｅ、吸収材５２の第１の端面５２ａ、および絞り壁１１２ｆによって囲まれたほぼ閉じた状態の空間が形成され、その空間内により圧力が高い高圧領域ＡＰが発生する。その結果、絞り壁１１２ｆがない場合に比べて、シール部材１２６ａと吸収材５２との間を介する室外空気Ａ３の第２の流路Ｐ２への侵入がより抑制される。 In the case of this embodiment, a throttle wall 112f extending toward the first end face 52a of the absorber 52 is provided at the tip of the collision plate 112e (the end far from the first seal unit 126). As a result, a substantially closed space surrounded by the sealing member 126a, the collision plate 112e, the first end surface 52a of the absorbent 52, and the restrictor wall 112f is formed, and a high pressure area AP having a higher pressure is formed in the space. Occur. As a result, intrusion of the outdoor air A3 into the second flow path P2 through the space between the sealing member 126a and the absorbent 52 is further suppressed as compared with the case where the throttle wall 112f is not provided.
　なお、図１６に示すように、第１のシールユニット１２６のシール部材１２６ａと第２のシールユニット１２８のシール部材１２８ａそれぞれは、吸収材５２の第１の端面５２ａおよび第２の端面５２ｂに対して直交する方向に吸収材５２に接触している。しかしながら、本開示の実施の形態はこれに限らない。 As shown in FIG. 16, the sealing member 126a of the first sealing unit 126 and the sealing member 128a of the second sealing unit 128 are arranged against the first end surface 52a and the second end surface 52b of the absorbent 52, respectively. contacting the absorber 52 in a direction orthogonal to the However, embodiments of the present disclosure are not limited to this.

　図１８に示すように、異なる実施の形態に係る換気装置において、シール部材１２６ａ、１２８ａそれぞれは、第１の端面５２ａおよび第２の端面５２ｂそれぞれに対して傾斜した状態で吸収材５２に接触する。具体的には、吸収材５２の回転方向ＤＲの上流側から下流側に向かうにしたがって吸収材５２に接近するように傾いた状態で、シール部材１２６ａ、１２８ａはシールホルダ２２６ｂ、２２８ｂに保持されている。この場合、図１６に示す実施の形態に比べて、シール部材１２６ａ、１２８ａと吸収材５２との間の摺動抵抗が低くなり、モータ５４に対する負荷が低下する。 As shown in FIG. 18, in a ventilator according to a different embodiment, each of the sealing members 126a and 128a contacts the absorbent material 52 while being inclined with respect to the first end surface 52a and the second end surface 52b. . Specifically, the seal members 126a and 128a are held by the seal holders 226b and 228b in an inclined state so as to approach the absorber 52 from the upstream side to the downstream side in the rotational direction DR of the absorber 52. there is In this case, the sliding resistance between the seal members 126a, 128a and the absorbing material 52 is lower than in the embodiment shown in FIG. 16, and the load on the motor 54 is reduced.
　なお、吸収材５２の回転方向が切り替わる場合、シール部材１２６ａ、１２８ａそれぞれは、吸収材５２の径方向に延在する回転中心線を中心として揺動可能にシールホルダに保持されてもよい。 When the rotational direction of the absorber 52 is switched, each of the seal members 126a and 128a may be held by the seal holder so as to be swingable about the center line of rotation extending in the radial direction of the absorber 52 .
　また、シール部材１２６ａと第１の端面５２ａとの間、およびシール部材１２８ａと第２の端面５２ｂとの間を室外空気Ａ３または室外空気Ａ４が通過しないように、第１のファン６２と第２のファン６６の回転数を調節してもよい。例えば第１のファン６２や第２のファン６６の回転速度が高くなると、第１の流路Ｐ１や第２の流路Ｐ２内の圧力が下がる。それとは逆に回転速度が低くなると圧力が上がる。 Further, the first fan 62 and the second fan 62 are arranged so that the outdoor air A3 or the outdoor air A4 does not pass between the seal member 126a and the first end surface 52a and between the seal member 128a and the second end surface 52b. You may adjust the rotation speed of the fan 66 of . For example, when the rotation speed of the first fan 62 and the second fan 66 increases, the pressure in the first flow path P1 and the second flow path P2 decreases. Conversely, as the rotation speed decreases, the pressure increases.
　例えば、第１のヒータ５８および第２のヒータ６０の少なくとも一方がＯＮの場合、第１のファン６２の回転速度を上げて第１の流路Ｐ１内の圧力を下げるおよび第２のファン６６の回転速度を下げて第２の流路Ｐ２内の圧力を上げる、の少なくともいずれかを行う。このことにより、加熱された室外空気Ａ３の第１のシールユニット１２６のシール部材１２６ａと吸収材５２との間の通過をより抑制することができる。 For example, when at least one of the first heater 58 and the second heater 60 is ON, the rotation speed of the first fan 62 is increased to decrease the pressure in the first flow path P1 and the second fan 66 is turned on. At least one of the following is performed: Decrease the rotation speed to increase the pressure in the second flow path P2. As a result, passage of the heated outdoor air A3 between the seal member 126a of the first seal unit 126 and the absorbent 52 can be further suppressed.
　吸収材５２に関するシールとして、第１のシールユニット１２６と第２のシールユニット１２８以外に、図１３に示すように、ラビリンスシール部材１３０を換気装置５０は備える。 In addition to the first seal unit 126 and the second seal unit 128, the ventilator 50 includes a labyrinth seal member 130 as a seal for the absorbent material 52, as shown in FIG.
　図１９は、吸収材ホルダ１１４の外側に形成されたラビリンス流路ＰＬを示す吸収材ホルダ１１４の概略的な断面図である。 19 is a schematic cross-sectional view of the absorbent holder 114 showing the labyrinth flow path PL formed outside the absorbent holder 114. FIG.
　図１９に示すように、吸収材ホルダ１１４は、回転するために、その円筒状部１１４ａの外周面が、ヒータベース部材１１２の吸収材収容部１１２ｂと仕切り板１２４に対して間隔をあけて対向している。そのため、本来、吸収材５２を通過すべき室外空気Ａ３の一部が、円筒状部１１４ａの外側を流れて吸収材５２をバイパスしうる。室外空気Ａ３が第１のヒータ５８および第２のヒータ６０の少なくとも一方によって加熱されている場合、このようなバイパスが発生すると、室外空気Ａ３が吸収材５２から奪う水分量が減少する。すなわち加湿運転の効率（室内Ｒｉｎの加湿効率）または除湿運転における再生運転の効率（吸収材５２の再生効率）が低下する。そこで、本実施の形態の場合、ラビリンスシール部材１３０により、吸収材ホルダ１１４とそれに対向する部材（ヒータベース部材１１２と仕切り板１２４）との間にラビリンス流路ＰＬが形成されている。なお、ラビリンス流路ＰＬは、流体の流れ方向を複数回変更させる流路形状を備えることによって高い流路抵抗を備える流路を言う。 As shown in FIG. 19, since the absorber holder 114 rotates, the outer peripheral surface of the cylindrical portion 114a faces the absorber containing portion 112b of the heater base member 112 and the partition plate 124 with a gap therebetween. are doing. Therefore, part of the outdoor air A3 that should pass through the absorbent 52 can bypass the absorbent 52 by flowing outside the cylindrical portion 114a. When the outdoor air A3 is heated by at least one of the first heater 58 and the second heater 60, the amount of moisture taken from the absorbent 52 by the outdoor air A3 is reduced when such a bypass occurs. That is, the efficiency of the humidification operation (humidification efficiency of the indoor Rin) or the efficiency of the regeneration operation (the regeneration efficiency of the absorbent 52) in the dehumidification operation decreases. Therefore, in the case of the present embodiment, the labyrinth seal member 130 forms a labyrinth flow path PL between the absorbent holder 114 and the members facing it (the heater base member 112 and the partition plate 124). The labyrinth flow path PL refers to a flow path having a high flow resistance due to the shape of the flow path that changes the flow direction of the fluid multiple times.
　ラビリンスシール部材１３０は、ラビリンス流路ＰＬの一部として、吸収材５２の径方向（Ｙ軸方向）に延在する径方向流路ＰＬａを形成する端面１３０ａを備える。具体的には、本実施の形態の場合、吸収材ホルダ１１４は、その円筒状部１１４ａの外周面に外歯１１４ｄを備える。また、吸収材ホルダ１１４は、吸収材５２の第１の端面５２ａから遠い側の外歯１１４ｄの端面に設けられた環状のフランジ１１４ｅを備える。ラビリンスシール部材１３０の端面１３０ａは、フランジ１１４ｅとの間に径方向流路ＰＬａを形成する。 The labyrinth seal member 130 includes an end surface 130a forming a radial flow path PLa extending in the radial direction (Y-axis direction) of the absorbent 52 as part of the labyrinth flow path PL. Specifically, in the case of this embodiment, absorber holder 114 has external teeth 114d on the outer peripheral surface of cylindrical portion 114a. The absorber holder 114 also has an annular flange 114e provided on the end face of the external tooth 114d on the far side from the first end face 52a of the absorber 52. As shown in FIG. An end surface 130a of the labyrinth seal member 130 forms a radial flow path PLa between itself and the flange 114e.
　このような径方向流路ＰＬａを含むラビリンス流路ＰＬにより、室外空気Ａ３は、円筒状部１１４ａの外側を流れて吸収材５２をバイパスし難くなり、吸収材５２を通過する。その結果、室外空気Ａ３が吸収材５２をバイパスすることよって生じる加湿運転の効率（室内Ｒｉｎの加湿効率）または除湿運転における再生運転の効率（吸収材５２の再生効率）の低下を抑制することができる。 The labyrinth flow path PL including such a radial flow path PLa makes it difficult for the outdoor air A3 to flow outside the cylindrical portion 114a and bypass the absorbent 52, so that it passes through the absorbent 52. As a result, it is possible to suppress a decrease in the efficiency of the humidification operation (humidification efficiency of the indoor Rin) or the efficiency of the regeneration operation in the dehumidification operation (the regeneration efficiency of the absorbent 52) caused by the outdoor air A3 bypassing the absorbent 52. can.
　また、本実施の形態の場合、ラビリンスシール部材１３０の端面１３０ａには、吸収材ホルダ１１４のフランジ１１４ｅに向かって突出する突条部１３０ｂが設けられている。これにより、ラビリンス流路ＰＬの流路抵抗がさらに増加する。 Further, in the case of the present embodiment, the end surface 130a of the labyrinth seal member 130 is provided with a ridge portion 130b that protrudes toward the flange 114e of the absorber holder 114. As shown in FIG. This further increases the channel resistance of the labyrinth channel PL.
　さらに、本実施の形態の場合、仕切り板１２４には、吸収材５２の第２の端面５２ｂに間隔をあけて対向するように吸収材５２の径方向（Ｙ軸方向）に延在するリブ１２４ａが設けられている。このリブ１２４ａにより、ラビリンス流路ＰＬから室外空気Ａ３が流出しにくくなり、その結果として、ラビリンス流路ＰＬの流路抵抗がさらに増加する。 Furthermore, in the case of the present embodiment, ribs 124a extending in the radial direction (Y-axis direction) of the absorbent 52 are provided on the partition plate 124 so as to face the second end surface 52b of the absorbent 52 with a gap therebetween. is provided. The rib 124a makes it difficult for the outdoor air A3 to flow out of the labyrinth flow path PL, and as a result, the flow path resistance of the labyrinth flow path PL further increases.
　さらにまた、本実施の形態の場合、仕切り板１２４のリブ１２４ａの先端に、吸収材５２の第２の端面５２ｂに向かって突出する突条部１２４ｂが設けられている。この突条部１２４ｂにより、ラビリンス流路ＰＬから室外空気Ａ３が流出しにくくなり、その結果として、ラビリンス流路ＰＬの流路抵抗がさらに増加する。 Furthermore, in the case of the present embodiment, the ribs 124a of the partition plate 124 are provided at their ends with ridges 124b that protrude toward the second end face 52b of the absorbent 52. As shown in FIG. The protrusion 124b makes it difficult for the outdoor air A3 to flow out of the labyrinth flow path PL, and as a result, the flow path resistance of the labyrinth flow path PL further increases.
　なお、ラビリンス流路ＰＬは、吸収材ホルダ１１４の円筒状部１１４ａの外周面全体にわたって形成してもよく、また全体にわたって形成しなくてもよい。ラビリンス流路ＰＬの主目的は、第１のヒータ５８および第２のヒータ６０の少なくとも１つによって加熱された室外空気Ａ３の多くが吸収材５２を通過するように、その室外空気Ａ３の吸収材５２のバイパスを抑制することである。したがって、加熱された室外空気Ａ３が通過する吸収材５２の部分に対応する吸収材ホルダ１１４の円筒状部１１４ａの部分の外側に、ラビリンス流路ＰＬが少なくとも存在すればよい。なお、円筒状部１１４ａの外周面全体にわたってラビリンス流路ＰＬを形成した場合、第２の端面５２ｂから第１の端面５２ａに向かって吸収材５２を通過する室外空気Ａ４についても、吸収材５２のバイパスを抑制することができる。 The labyrinth flow path PL may be formed over the entire outer peripheral surface of the cylindrical portion 114a of the absorbent holder 114, or may not be formed over the entire surface. The main purpose of the labyrinth flow path PL is to absorb the outdoor air A3 so that most of the outdoor air A3 heated by at least one of the first heater 58 and the second heater 60 passes through the absorbent 52. 52 bypass is suppressed. Therefore, it is sufficient that at least the labyrinth flow path PL exists outside the portion of the cylindrical portion 114a of the absorbent holder 114 corresponding to the portion of the absorbent 52 through which the heated outdoor air A3 passes. Note that when the labyrinth flow path PL is formed over the entire outer peripheral surface of the cylindrical portion 114a, the outdoor air A4 passing through the absorbent 52 from the second end face 52b toward the first end face 52a also passes through the absorbent 52. Bypass can be suppressed.
　また、本実施の形態の場合、ラビリンスシール部材１３０の端面１３０ａは、吸収材ホルダ１１４のフランジ１１４ｅとの間に径方向流路ＰＬａを形成する。ラビリンスシール部材１３０の端面１３０ａと協働して径方向流路ＰＬａを形成する吸収材ホルダ１１４の部分は、フランジ１１４ｅに限らない。吸収材ホルダ１１４が径方向外側に突出する拡径部を備えていれば、ラビリンスシール部材１３０の端面１３０ａはその拡径部との間に、径方向流路ＰＬａを形成することが可能である。なお、フランジ１１４ｅは、外歯１１４ｄの歯間を流れる室外空気Ａ３を妨害するものであり、これによっても、ラビリンス流路ＰＬの流路抵抗が増加している。 In addition, in the case of the present embodiment, the end face 130a of the labyrinth seal member 130 forms the radial flow path PLa between the flange 114e of the absorbent holder 114 and the end face 130a. The portion of the absorbent holder 114 that cooperates with the end surface 130a of the labyrinth seal member 130 to form the radial flow path PLa is not limited to the flange 114e. If the absorber holder 114 has an enlarged diameter portion that protrudes radially outward, the end surface 130a of the labyrinth seal member 130 can form a radial flow path PLa between the enlarged diameter portion and the enlarged diameter portion. . The flange 114e obstructs the outdoor air A3 flowing between the teeth of the external teeth 114d, which also increases the flow path resistance of the labyrinth flow path PL.
　吸収材５２を通過した室外空気Ａ３は、第２の空間Ｓ２内に流入する。 The outdoor air A3 that has passed through the absorbent 52 flows into the second space S2.
　図２０は、第１のファン６２まわりの構成要素を示す概略的な断面図である。 FIG. 20 is a schematic cross-sectional view showing components around the first fan 62. FIG.
　図２０に示すように、第１の流路Ｐ１を流れる、具体的には第２の空間Ｓ２内に流入した室外空気Ａ３は、第１のファン６２に吸い込まれる。本実施の形態の場合、第１のファン６２は、シロッコファンであって、ファン室Ｆ２に配置された上下方向（Ｚ軸方向）に延在する回転中心線を中心にして回転する羽根車６２ａと、羽根車６２ａを回転させるモータ６２ｂとから構成されている。室外空気Ａ３は、羽根車６６ａ内の回転により、ファン室Ｆ２に吸い込まれる。なお、ファン室Ｆ２は、仕切り板１２４上に設けられた環状壁１２４ｃと環状壁１２４ｃ上に取り付けられるファンカバー部材１３２によって画定されている。仕切り板１２４には、ファン室Ｆ２に連通して室外空気Ａ３が通過する空気吸い込み口１２４ｄが形成されている。 As shown in FIG. 20, the outdoor air A3 that flows through the first flow path P1, specifically, that has flowed into the second space S2, is sucked into the first fan 62. As shown in FIG. In the case of this embodiment, the first fan 62 is a sirocco fan, and an impeller 62a that rotates around a rotation center line extending in the vertical direction (Z-axis direction) arranged in the fan chamber F2. and a motor 62b for rotating the impeller 62a. The outdoor air A3 is sucked into the fan chamber F2 by the rotation inside the impeller 66a. The fan chamber F2 is defined by an annular wall 124c provided on the partition plate 124 and a fan cover member 132 attached on the annular wall 124c. The partition plate 124 is formed with an air suction port 124d that communicates with the fan chamber F2 and through which the outdoor air A3 passes.
　本実施の形態の場合、第１のファン６２のモータ６２ｂは、ファンカバー部材１３２上に設けられ、モータカバー部材１３４によって覆われている。すなわち、モータ６２ｂは、ファンカバー部材１３２とモータカバー部材１３４によって画定されたモータ室Ｍ１に格納されている。 In the case of this embodiment, the motor 62b of the first fan 62 is provided on the fan cover member 132 and covered with the motor cover member 134. That is, the motor 62b is housed in a motor chamber M1 defined by the fan cover member 132 and the motor cover member 134. As shown in FIG.
　本実施の形態の場合、モータ室Ｍ１内に室外空気Ａ３が流入するように、ファンカバー部材１３２とモータカバー部材１３４とが構成されている。 In the case of this embodiment, the fan cover member 132 and the motor cover member 134 are configured so that the outdoor air A3 flows into the motor chamber M1.
　具体的に説明すると、第１のファン６２が回転すると、図８および図９に示すように、第３の吸気口１０２ｇおよび第４の吸気口１０２ｈを介して、室外空気Ａ３が第１の空間Ｓ１内に流入する。第１の空間Ｓ１内に流入した室外空気Ａ３は、その一部がそのまま第１のヒータ５８および第２のヒータ６０を通過する。その残りは、図２０に示すように、モータ室Ｍ１内に流入し、モータ６２ｂを冷却してモータ室Ｍ１から流出し、そして、第１のヒータ５８および第２のヒータ６０を通過する。 Specifically, when the first fan 62 rotates, as shown in FIGS. 8 and 9, the outdoor air A3 flows into the first space through the third air intake port 102g and the fourth air intake port 102h. It flows into S1. Part of the outdoor air A3 that has flowed into the first space S1 passes through the first heater 58 and the second heater 60 as they are. The remainder flows into motor chamber M1, cools motor 62b, flows out of motor chamber M1, and passes through first heater 58 and second heater 60, as shown in FIG.
　モータ室Ｍ１内に侵入する室外空気Ａ３が局所的に上下方向（Ｚ軸方向）に流れるように、ファンカバー部材１３２とモータカバー部材１３４それぞれには、上下方向に延在する複数の障害壁１３２ａ、１３４ａが設けられている。これらの障害壁１３２ａ、１３４ａにより、室外空気Ａ３が上下方向に流れ、室外空気Ａ３に同伴する異物が重力によって取り除かれる。その結果、モータ室Ｍ１への異物の侵入が抑制されている。 The fan cover member 132 and the motor cover member 134 each have a plurality of obstacle walls 132a extending in the vertical direction so that the outdoor air A3 entering the motor chamber M1 locally flows in the vertical direction (the Z-axis direction). , 134a are provided. The obstacle walls 132a and 134a allow the outdoor air A3 to flow vertically, and the foreign matter entrained in the outdoor air A3 is removed by gravity. As a result, entry of foreign matter into the motor chamber M1 is suppressed.
　また、第１の空間Ｓ１に連通する第４の吸気口１０２ｈには、異物の侵入を抑制する複数の桟１０２ｍが設けられている。さらに、少なくとも１つの桟１０２ｍの上面１０２ｎには、第１の空間Ｓ１側が高い傾斜面１０２ｏが形成されている。この傾斜面１０２ｏにより、斜め下方向に降る雨水の第１の空間Ｓ１内への侵入が抑制される。なお、同様の桟１０２ｍが、第１の吸気口１０２ａ、第２の吸気口１０２ｂ、および第３の吸気口１０２ｇにも設けられている。 In addition, a plurality of crosspieces 102m for suppressing entry of foreign matter are provided in the fourth air inlet 102h communicating with the first space S1. Further, an upper surface 102n of at least one crosspiece 102m is formed with an inclined surface 102o that is higher on the first space S1 side. The inclined surface 102o suppresses rainwater falling obliquely downward from entering the first space S1. Similar crosspieces 102m are also provided at the first air inlet 102a, the second air inlet 102b, and the third air inlet 102g.
　なお、雨水の侵入を抑制する手段は、傾斜面１０２ｏに限らない。 It should be noted that the means for suppressing intrusion of rainwater is not limited to the inclined surface 102o.
　図２１は、異なる実施の形態に係る換気装置における、筺体２０２の第４の吸気口２０２ｈの構成を示す概略的な断面図である。 FIG. 21 is a schematic cross-sectional view showing the configuration of the fourth air inlet 202h of the housing 202 in a ventilator according to another embodiment.
　図２１に示すように、異なる実施の形態に係る換気装置において、筺体２０２の第４の吸気口２０２ｈには、複数の桟２０２ｍが設けられている。桟２０２ｍそれぞれには、下方に位置する他の桟２０２ｍに向かって延在する垂れ下がり部２０２ｐが設けられている。このような垂れ下がり部２０２ｐによっても、雨水の第１の空間Ｓ１内への侵入を抑制することができる。 As shown in FIG. 21, in a ventilator according to a different embodiment, the fourth air inlet 202h of the housing 202 is provided with a plurality of crosspieces 202m. Each crosspiece 202m is provided with a hanging portion 202p extending toward another crosspiece 202m located below. The drooping portion 202p can also prevent rainwater from entering the first space S1.
　本実施の形態の場合、図１０および図１５に示すように、吸収材５２から空気吸い込み口１２４ｄとの間の第１の流路Ｐ１の部分、すなわち第２の空間Ｓ２内には、オリフィス部材１３６が設けられている。オリフィス部材１３６は、吸収材５２から空気吸い込み口１２４ｄとの間の第１の流路Ｐ１の部分において、局所的に流路断面積を小さくするための障害物である。オリフィス部材１３６を設けることにより、オリフィス部材１３６を設けない場合に比べて第２の空間Ｓ２内の温度分布が一様化される。 In the case of this embodiment, as shown in FIGS. 10 and 15, the portion of the first flow path P1 between the absorbent 52 and the air suction port 124d, that is, the second space S2 has an orifice member 136 is provided. The orifice member 136 is an obstacle for locally reducing the flow passage cross-sectional area in the portion of the first flow passage P1 between the absorbent 52 and the air suction port 124d. By providing the orifice member 136, the temperature distribution in the second space S2 is made more uniform than when the orifice member 136 is not provided.
　具体的に説明すると、第２の空間Ｓ２には、第１のヒータ５８を通過した室外空気Ａ３と第２のヒータ６０を通過した室外空気Ａ３が混ざりながら流れる。第１のヒータ５８と第２のヒータ６０の両方がＯＮである場合と両方がＯＦＦである場合、第２の空間Ｓ２内の温度分布は実質的に一様である。 Specifically, in the second space S2, the outdoor air A3 that has passed through the first heater 58 and the outdoor air A3 that has passed through the second heater 60 flow while being mixed. The temperature distribution in the second space S2 is substantially uniform when both the first heater 58 and the second heater 60 are ON and when both are OFF.
　これに対して、第１のヒータ５８のみがＯＮである場合の温度分布と第２のヒータ６０のみがＯＮである場合の温度分布は、それぞれ一様でなく、また互いに大きく異なる。具体的には、換気装置５０の後側に配置されている第１のヒータ５８を通過した室外空気Ａ３は第２の空間Ｓ２において後側部分を流れ、前側に配置されている第２のヒータ６０を通過した室外空気Ａ３は第２の空間Ｓ２において前側部分を流れる。第２の空間Ｓ２を流れる室外空気Ａ３は、第１のファン６２の空気吸い込み口１２４ｄ近傍で旋回し始め、その状態で空気吸い込み口１２４ｄを介してファン室Ｆ２に流入する。このとき、例えば後側の第１のヒータ５８のみＯＮである場合、第２の空間Ｓ２内の後側部分を温度が高い室外空気Ａ３が流れ、前側部分を温度が低い（加熱されていない）室外空気Ａ３が流れる。この状態で室外空気Ａ３が空気吸い込み口１２４ｄ近傍で旋回すると、第２の空間Ｓ２内の室外空気Ａ３の温度を測定する温度センサ１３８の検出精度が低下する。なお、温度センサ１３８は、図９に示すように仕切り板１２４に設けられている。 On the other hand, the temperature distribution when only the first heater 58 is ON and the temperature distribution when only the second heater 60 is ON are not uniform and differ greatly from each other. Specifically, the outdoor air A3 that has passed through the first heater 58 arranged on the rear side of the ventilator 50 flows through the rear portion of the second space S2, and flows through the second heater arranged on the front side. The outdoor air A3 that has passed through 60 flows through the front portion of the second space S2. The outdoor air A3 flowing through the second space S2 begins to swirl in the vicinity of the air intake port 124d of the first fan 62, and then flows into the fan chamber F2 through the air intake port 124d. At this time, for example, when only the first heater 58 on the rear side is ON, the outdoor air A3 having a high temperature flows through the rear portion of the second space S2, and the temperature of the front portion is low (not heated). Outdoor air A3 flows. If the outdoor air A3 swirls in the vicinity of the air intake port 124d in this state, the detection accuracy of the temperature sensor 138 that measures the temperature of the outdoor air A3 in the second space S2 is lowered. Note that the temperature sensor 138 is provided on the partition plate 124 as shown in FIG.
　図１５に示すように、オリフィス部材１３６は、第１および第２のヒータ５８、６０から空気吸い込み口１２４ｄまでの第１の流路Ｐ１の部分（第２の空間Ｓ２）において、温度センサ１３８に対して上流側に配置されている。また、オリフィス部材１３６は、第２の空間Ｓ２を横断するように設けられている。したがって、図１０に示すように、第１のヒータ５８を通過した室外空気Ａ３と第２のヒータ６０を通過した室外空気Ａ３は、オリフィス部材１３６と仕切り板１２４との間の狭い隙間を通過して空気吸い込み口１２４ｄに向かう。その隙間と隙間を通過後に発生する剥離流による渦により、第１のヒータ５８を通過した室外空気Ａ３と第２のヒータ６０を通過した室外空気Ａ３が適度に混ざり合う。その結果、オリフィス部材１３６の下流側に位置する温度センサ１３８の周囲において、第１のヒータ５８のみがＯＮである場合の温度分布と第２のヒータ６０のみがＯＮである場合の温度分布が略等しくなる。なお、オリフィス部材１３６には、副次的な効果として、第１のファン６２によって発生して室外Ｒｏｕｔに漏れる騒音レベルを低減する効果もある。 As shown in FIG. 15, the orifice member 136 is connected to the temperature sensor 138 in the portion (second space S2) of the first flow path P1 from the first and second heaters 58, 60 to the air intake port 124d. It is arranged on the upstream side. Also, the orifice member 136 is provided so as to cross the second space S2. Therefore, as shown in FIG. 10, the outdoor air A3 that has passed through the first heater 58 and the outdoor air A3 that has passed through the second heater 60 pass through the narrow gap between the orifice member 136 and the partition plate 124. to the air intake port 124d. The outdoor air A3 that has passed through the first heater 58 and the outdoor air A3 that has passed through the second heater 60 are appropriately mixed by the vortex caused by the separation flow generated after passing through the gap. As a result, around the temperature sensor 138 located downstream of the orifice member 136, the temperature distribution when only the first heater 58 is ON and the temperature distribution when only the second heater 60 is ON are substantially equal to each other. be equal. As a secondary effect, the orifice member 136 also has the effect of reducing the level of noise generated by the first fan 62 and leaking to the outdoor Rout.
　なお、オリフィス部材１３６は、他の形状も可能である。 It should be noted that the orifice member 136 can also have other shapes.
　図２２は、異なる実施の形態に係る換気装置における、第２の空間Ｓ２を示す換気装置の筺体１０２の一部分の上面図である。 FIG. 22 is a top view of part of the ventilation device housing 102 showing the second space S2 in a ventilation device according to a different embodiment.
　図２２に示すように、異なる実施の形態に係る換気装置おいて、オリフィス部材２３６は、第２の空間Ｓ２を横断するように設けられておらず、換気装置の前側のみに設けられている。この場合、第１のヒータ５８を通過した室外空気Ａ３と第２のヒータ６０を通過した室外空気Ａ４は、上方視（Ｚ軸方向視）でオリフィス部材２３６をバイパスするように流れる。バイパスするときに、第１のヒータ５８を通過した室外空気Ａ３と第２のヒータ６０を通過した室外空気Ａ３とが適度に混ざり合う。この場合、温度センサ１３８近くでは室外空気Ａ３が緩やかに流れ、温度センサ１３８の測定環境が安定する。 As shown in FIG. 22, in a ventilator according to a different embodiment, the orifice member 236 is not provided across the second space S2, but is provided only on the front side of the ventilator. In this case, the outdoor air A3 that has passed through the first heater 58 and the outdoor air A4 that has passed through the second heater 60 flow so as to bypass the orifice member 236 when viewed from above (as viewed in the Z-axis direction). When bypassing, the outdoor air A3 that has passed through the first heater 58 and the outdoor air A3 that has passed through the second heater 60 are mixed appropriately. In this case, the outdoor air A3 gently flows near the temperature sensor 138, and the measurement environment of the temperature sensor 138 is stabilized.
　図２０に示すように、第２の空間Ｓ２から第１のファン６２のファン室Ｆ２に流入した室外空気Ａ３は、羽根車６２ａの回転よってダンパ装置６４に送られる。 As shown in FIG. 20, the outdoor air A3 that has flowed from the second space S2 into the fan chamber F2 of the first fan 62 is sent to the damper device 64 by the rotation of the impeller 62a.
　図２３Ａは、室内Ｒｉｎに接続した状態のダンパ装置６４を示す断面図である。また、図２３Ｂは、室外Ｒｏｕｔに接続した状態のダンパ装置６４を示す断面図である。 FIG. 23A is a cross-sectional view showing the damper device 64 connected to the room Rin. Also, FIG. 23B is a sectional view showing the damper device 64 connected to the outdoor Route.
　図２３Ａおよび図２３Ｂ、それに加えて図９に示すように、本実施の形態の場合、ダンパ装置６４は、仕切り板１２４の一部分とファンカバー部材１３２の一部分とを、そのハウジングの構成要素として備える。また、ダンパ装置６４は、室外空気Ａ３が流入する流入口６４ａと、室内機２０に連通して室外空気Ａ３が流出する第１の流出口６４ｂと、を含んでいる。また、ダンパ装置６４は、室外Ｒｏｕｔに連通して室外空気Ａ３が流出する第２の流出口６４ｃと、第１の流出口６４ｂおよび第２の流出口６４ｃの一方を選択的に閉じる閉鎖扉６４ｄと、を含んでいる。なお、ダンパ装置６４は、高さ方向（Ｚ軸方向）に延在する回転中心線を中心にして閉鎖扉６４ｄを回転駆動し、空気調和機１０の制御装置によって制御されるモータなどの動力源（図示せず）も含んでいる。 As shown in FIGS. 23A and 23B and also in FIG. 9, in the case of this embodiment, the damper device 64 includes a portion of the partition plate 124 and a portion of the fan cover member 132 as components of its housing. . The damper device 64 also includes an inflow port 64a into which the outdoor air A3 flows, and a first outflow port 64b that communicates with the indoor unit 20 and out of which the outdoor air A3 flows out. Further, the damper device 64 has a second outlet 64c communicating with the outdoor Rout and through which the outdoor air A3 flows out, and a closing door 64d that selectively closes one of the first outlet 64b and the second outlet 64c. and includes The damper device 64 rotates the closing door 64d around a rotation center line extending in the height direction (Z-axis direction), and a power source such as a motor controlled by the control device of the air conditioner 10. (not shown).
　ダンパ装置６４の流入口６４ａは、第１のファン６２のファン室Ｆ２に連通している。それにより、第１のヒータ５８、第２のヒータ６０、および吸収材５２を通過し、第１のファン６２の羽根車６２ａから吹き出された室外空気Ａ３が、流入口６４ａを介してダンパ装置６４内に流入する。 The inlet 64 a of the damper device 64 communicates with the fan chamber F 2 of the first fan 62 . As a result, the outdoor air A3 that has passed through the first heater 58, the second heater 60, and the absorbent 52 and is blown out from the impeller 62a of the first fan 62 passes through the inlet 64a to the damper device 64. flow inside.
　ダンパ装置６４の第１の流出口６４ｂには換気導管５６が接続される。これにより、第１の流出口６４ｂは、換気導管５６を介して室内機２０内に連通する。その結果、流入口６４ａを通過した室外空気Ａ３が室内機２０内に流入する。なお、本実施の形態の場合、第１の流出口６４ｂは、右方向に開口している。 A ventilation conduit 56 is connected to the first outflow port 64 b of the damper device 64 . Thereby, the first outflow port 64b communicates with the interior of the indoor unit 20 via the ventilation conduit 56 . As a result, the outdoor air A3 that has passed through the inlet 64 a flows into the indoor unit 20 . In addition, in the case of the present embodiment, the first outflow port 64b opens rightward.
　また、本実施の形態の場合、ダンパ装置６４の第１の流出口６４ｂの開口方向が右方向であって、流入口６４ａの開口方向は、その逆の左方向である。そのため、流入口６４ａに流入した室外空気Ａ３は、その流れ方向を変更することなく、第１の流出口６４ｂから流出する。そのため、室外空気Ａ３は、第１のファン６２の吹き出し速度を維持したまま減速することなく、換気導管５６内に流入することができる。 Further, in the case of the present embodiment, the opening direction of the first outflow port 64b of the damper device 64 is the right direction, and the opening direction of the inflow port 64a is the opposite left direction. Therefore, the outdoor air A3 that has flowed into the inflow port 64a flows out from the first outflow port 64b without changing its flow direction. Therefore, the outdoor air A3 can flow into the ventilation conduit 56 while maintaining the blowing speed of the first fan 62 without deceleration.
　ダンパ装置６４の第２の流出口６４ｃは、直接的ではなく、間接的に室外Ｒｏｕｔに連通する。具体的には、第２の流出口６４ｃは、筺体１０２内に設けられた隔離室Ｓ６内で、水平方向、特に後壁１０２ｅに向いた状態で開口している。隔離室Ｓ６は、筺体１０２とファンカバー部材１３２とによって画定され、他の空間Ｓ１～Ｓ４から独立している。したがって、第２の流出口６４ｃから流出する室外空気Ａ３は、隔離室Ｓ６内に流出する。 The second outflow port 64c of the damper device 64 communicates with the outdoor route indirectly, not directly. Specifically, the second outflow port 64c opens in the isolation chamber S6 provided in the housing 102 in a horizontal direction, particularly in a state facing the rear wall 102e. The isolation chamber S6 is defined by the housing 102 and the fan cover member 132 and is independent of the other spaces S1-S4. Therefore, the outdoor air A3 flowing out from the second outlet 64c flows into the isolation chamber S6.
　隔離室Ｓ６を画定する筺体１０２の底板１０２ｆには、室外機３０の本体の筺体１００内に連通する接続口１０２ｑが設けられている。 A connection port 102q that communicates with the inside of the housing 100 of the main body of the outdoor unit 30 is provided on the bottom plate 102f of the housing 102 that defines the isolation room S6.
　図２４は、ダンパ装置６４から流出した室外空気Ａ３の流れを示す換気装置５０の断面斜視図である。また、図２５は、室外機３０の本体内部を概略的に示す室外機３０の正面図である。 24 is a cross-sectional perspective view of the ventilator 50 showing the flow of the outdoor air A3 flowing out from the damper device 64. FIG. 25 is a front view of the outdoor unit 30 schematically showing the inside of the main body of the outdoor unit 30. As shown in FIG.
　図２４に示すように、ダンパ装置６４の第２の流出口６４ｃから後方向に流出した室外空気Ａ３は、隔離室Ｓ６内で流れ方向を下方向に変え、筺体１０２の底板１０２ｆに設けられた接続口１０２ｑを通過する。 As shown in FIG. 24, the outdoor air A3 flowing backward from the second outflow port 64c of the damper device 64 changes its flow direction downward in the isolated chamber S6, and is provided on the bottom plate 102f of the housing 102. It passes through the connection port 102q.
　図２５に示すように、筺体１０２の底板１０２ｆの接続口１０２ｑを通過した室外空気Ａ３は、室外機３０の本体の筺体１００内に流入する。 As shown in FIG. 25, the outdoor air A3 that has passed through the connection port 102q of the bottom plate 102f of the housing 102 flows into the housing 100 of the main body of the outdoor unit 30.
　本実施の形態の場合、本体の筺体１００内は、室外熱交換器３２やファン３４などを格納する熱交換室Ｒ１と、圧縮機３６、四方弁４０、制御基板などを格納する機械室Ｒ２とに、大略分かれている。室外空気Ａ３は、機械室Ｒ２内に流入する。 In the case of the present embodiment, the housing 100 of the main body includes a heat exchange chamber R1 that houses the outdoor heat exchanger 32, the fan 34, and the like, and a machine room R2 that houses the compressor 36, the four-way valve 40, the control board, and the like. are roughly divided into The outdoor air A3 flows into the machine room R2.
　このように、ダンパ装置６４の第２の流出口６４ｃから流出する室外空気Ａ３を、室外機３０の本体の筺体１００を介して、室外Ｒｏｕｔに排出する理由について説明する。 The reason why the outdoor air A3 flowing out from the second outlet 64c of the damper device 64 is thus discharged to the outdoor Rout via the housing 100 of the main body of the outdoor unit 30 will be explained.
　図２３Ｂに示すように、第２の流出口６４ｃから流出する場合、室外空気Ａ３は、閉鎖扉６４ｄに衝突してその流れ方向を実質的に９０度変更する。このとき、ダンパ装置６４内に乱流が発生し、その結果として騒音が発生する。 As shown in FIG. 23B, when flowing out from the second outlet 64c, the outdoor air A3 collides with the closing door 64d and changes its flow direction by substantially 90 degrees. At this time, turbulence is generated in the damper device 64, resulting in noise.
　ここで、仮に第２の流出口６４ｃに対向する筺体１０２の後壁１０２ｅの部分に複数の桟を備える排気口を設けた場合、乱流由来の騒音がその排気口を介して、室外Ｒｏｕｔに漏れる。また、閉鎖扉６４ｄの動作音もその排気口を介して室外Ｒｏｕｔに漏れる。さらに、桟によって風切り音が発生しうる。 Here, if an exhaust port provided with a plurality of crosspieces is provided in the portion of the rear wall 102e of the housing 102 facing the second outflow port 64c, the noise derived from the turbulence flows into the outdoor Rout through the exhaust port. Leak. Further, the operation sound of the closing door 64d also leaks to the outdoor Rout through the exhaust port. Additionally, the crosspieces can generate wind noise.
　本実施の形態のように、第２の流出口６４ｃから流出した室外空気Ａ３が隔離室Ｓ６を介して筺体１００内に流入する場合、乱流由来の騒音や閉鎖扉６４ｄの動作音が室外Ｒｏｕｔに漏れることが抑制される。すなわち、筺体１００の内部空間が、室外空気Ａ３がダンパ装置６４を流れることによって発生して室外Ｒｏｕｔに漏れる騒音のレベルを低下させる「マフラー」として機能する。 As in the present embodiment, when the outdoor air A3 flowing out from the second outlet 64c flows into the housing 100 via the isolation chamber S6, noise derived from turbulence and operation noise of the closing door 64d are generated by the outdoor Rout. is suppressed. That is, the internal space of the housing 100 functions as a "muffler" that reduces the level of noise that is generated when the outdoor air A3 flows through the damper device 64 and leaks to the outdoor Rout.
　特に、室外空気Ａ３が機械室Ｒ２に流入する場合、さらに室外Ｒｏｕｔに漏れる騒音のレベルを低下させることができる。機械室Ｒ２は、略密閉空間であって、その中に格納されている圧縮機３６などから発生する熱が室外Ｒｏｕｔに流出できる程度の隙間を介して室外Ｒｏｕｔに連絡している。一方、熱交換室Ｒ１は、ファン３４によって吸い込まれる室外空気Ａ２が通過する吸気口および熱交換した後の室外空気Ａ２が流出する排気口を介して、室外Ｒｏｕｔに連絡している。したがって、機械室Ｒ２にダンパ装置６４の第２の流出口６４ｃから流出した室外空気Ａ３が流入する方が、熱交換室Ｒ１に流入する場合に比べて、室外Ｒｏｕｔに漏れる騒音のレベルを低下させることができる。 Especially when the outdoor air A3 flows into the machine room R2, the level of noise leaking to the outdoor Rout can be further reduced. The machine room R2 is a substantially closed space, and communicates with the outdoor route through a gap that allows the heat generated from the compressor 36 and the like housed therein to flow out to the outdoor route. On the other hand, the heat exchange chamber R1 communicates with the outdoor Rout via an intake port through which the outdoor air A2 sucked by the fan 34 passes and an exhaust port through which the outdoor air A2 after heat exchange flows out. Therefore, when the outdoor air A3 flowing out from the second outlet 64c of the damper device 64 flows into the machine room R2, the level of noise leaking to the outdoor Rout is reduced as compared with the case of flowing into the heat exchange room R1. be able to.
　このようにダンパ装置６４が室外機３０の本体の筺体１００内の空間を介して室外空気Ａ３を室外Ｒｏｕｔに排出することにより、室外機３０から発生する騒音のレベルを低下させることができる。 As described above, the damper device 64 discharges the outdoor air A3 to the outdoor Rout through the space in the housing 100 of the main body of the outdoor unit 30, so that the level of noise generated from the outdoor unit 30 can be reduced.
　なお、ダンパ装置６４の第２の流出口６４ｃから筺体１００に連通する接続口１０２ｑに向かって室外空気Ａ３がスムーズに流れるように、つまりこれらの間で乱流が発生して騒音が生じないように、以下のようにしてもよい。すなわち、第２の流出口６４ｃと接続口１０２ｑとを接続するダクトが、筺体１０２内に設けられてもよい。 The outdoor air A3 should flow smoothly from the second outflow port 64c of the damper device 64 toward the connection port 102q communicating with the housing 100. Alternatively, you can do the following: That is, a duct may be provided in the housing 102 to connect the second outflow port 64c and the connection port 102q.
　また、隔離室Ｓ６内でダンパ装置６４の第２の流出口６４ｃと接続口１０２ｑとが対向するように、第２の流出口６４ｃが下方向に向くようにダンパ装置６４は構成されてもよい。さらに、ダンパ装置６４の第２の流出口６４ｃが接続口１０２ｑに直接的に接続するように、ダンパ装置６４は構成されてもよい。 Further, the damper device 64 may be configured such that the second outflow port 64c of the damper device 64 faces downward so that the connection port 102q faces the second outflow port 64c of the damper device 64 in the isolation chamber S6. . Furthermore, the damper device 64 may be configured such that the second outflow port 64c of the damper device 64 is directly connected to the connection port 102q.
　ダンパ装置６４の第１の流出口６４ｂから流出した室外空気Ａ３は、換気導管５６を介して、室内機２０内に流入する。 The outdoor air A3 flowing out from the first outflow port 64b of the damper device 64 flows into the indoor unit 20 via the ventilation conduit 56.
　図２６は、室内機２０に設けられた室内熱交換器２２とノズル１４０を示す斜視図である。また、図２７は、内部構造を示す室内機２０の側面図である。なお、図に示すＵ－Ｖ－Ｗ直交座標系は、実施の形態の理解を容易にするためのものであって、実施の形態を限定するものではない。Ｕ軸方向は室内機２０の左右方向を示し、Ｖ軸方向は前後方向を示し、Ｗ軸方向は高さ方向（上下方向）を示している。 26 is a perspective view showing the indoor heat exchanger 22 and the nozzle 140 provided in the indoor unit 20. FIG. Moreover, FIG. 27 is a side view of the indoor unit 20 which shows an internal structure. The UVW orthogonal coordinate system shown in the drawing is for facilitating understanding of the embodiments, and does not limit the embodiments. The U-axis direction indicates the horizontal direction of the indoor unit 20, the V-axis direction indicates the front-rear direction, and the W-axis direction indicates the height direction (vertical direction).
　図２６に示すように、室内機２０は、室内熱交換器２２と、ノズル１４０とを備える。ノズル１４０は、換気導管５６と接続する接続部１４０ａと、換気導管５６から供給された室外空気Ａ３を吹き出す吹き出し口１４０ｂとを備える。 As shown in FIG. 26, the indoor unit 20 includes an indoor heat exchanger 22 and a nozzle 140. The nozzle 140 includes a connecting portion 140a connected to the ventilation conduit 56 and an outlet 140b for blowing out the outdoor air A3 supplied from the ventilation conduit 56. As shown in FIG.
　図２７に示すように、ノズル１４０は、室内機２０の筺体１４２内に換気装置５０から換気導管５６を介して供給された室外空気Ａ３を吹き出すように、室内機２０の筺体１４２内に設けられている。具体的には、ノズル１４０は、吹き出した室外空気Ａ３が室内機２０内における乾燥領域を通過してファン２４に向かうように室内機２０内に配置されている。ファン２４は、例えばクロスフローファンである。また、ここで言う「乾燥領域」とは、他の領域に比べて乾燥している領域である。このような「乾燥領域」は、実験的にまたはシミュレーションによって特定することができる。 As shown in FIG. 27, the nozzle 140 is provided in the housing 142 of the indoor unit 20 so as to blow out the outdoor air A3 supplied from the ventilation device 50 through the ventilation conduit 56 into the housing 142 of the indoor unit 20. ing. Specifically, the nozzle 140 is arranged inside the indoor unit 20 so that the blown outdoor air A3 passes through the dry area inside the indoor unit 20 and heads toward the fan 24 . Fan 24 is, for example, a cross-flow fan. Also, the “dry region” referred to here is a region that is drier than other regions. Such "dry areas" can be identified experimentally or by simulation.
　本実施の形態の場合、ノズル１４０の室外空気Ａ３の吹き出し方向が、吹き出し口１４０ｂから吹き出した室外空気Ａ３が室内機２０内の「乾燥領域」としての室内熱交換器２２の乾燥部分ＤＰを通過するように、方向付けされている。 In the case of the present embodiment, the direction in which the outdoor air A3 is blown from the nozzle 140 is such that the outdoor air A3 blown from the outlet 140b passes through the dry portion DP of the indoor heat exchanger 22 serving as the "dry region" in the indoor unit 20. It is oriented to
　具体的に説明すると、本実施の形態の場合、図２７に示すように、ファン２４の回転中心線の延在方向視（Ｕ軸方向視）で、室内熱交換器２２は、以下のように設けられている。すなわち、室内熱交換器２２は、ファン２４を部分的に囲むように（本実施の形態の場合はファン２４の下方を除いて囲むように）室内機２０の筺体１４２内に設けられている。室内熱交換器２２はまた、ファン２４の後方に位置する第１の部分２２ａと、ファン２４の前側に位置する第２の部分２２ｂとから構成されている。このような室内熱交換器２２内を、圧縮機３６から供給された冷媒が流れる。本実施の形態の場合、空気調和機１０の冷房運転または弱冷房運転（除湿運転）時、ファン２４の回転中心線の延在方向視で、冷媒は、第１の部分２２ａの上部から下部に向かって流れ、そして、第２の部分２２ｂの下部から上部に向かって流れる。すなわち、冷媒は、図２７において、反時計方向に室内熱交換器２２内を流れる。 Specifically, in the case of the present embodiment, as shown in FIG. 27, the indoor heat exchanger 22 is arranged as follows when viewed in the direction in which the rotation center line of the fan 24 extends (viewed in the U-axis direction). is provided. That is, the indoor heat exchanger 22 is provided inside the housing 142 of the indoor unit 20 so as to partially surround the fan 24 (in this embodiment, surround the fan 24 except for the area below it). The indoor heat exchanger 22 is also composed of a first portion 22a located behind the fan 24 and a second portion 22b located in front of the fan 24. As shown in FIG. Refrigerant supplied from the compressor 36 flows through the indoor heat exchanger 22 as described above. In the case of the present embodiment, when the air conditioner 10 is in cooling operation or low cooling operation (dehumidifying operation), the refrigerant flows from the upper portion to the lower portion of the first portion 22a as viewed in the extending direction of the rotation center line of the fan 24. It flows toward and then flows from the bottom to the top of the second portion 22b. That is, the refrigerant flows in the indoor heat exchanger 22 counterclockwise in FIG.
　このような冷媒の流れの結果、室内熱交換器２２の第２の部分２２ｂの上部に乾燥部分ＤＰが発生する。乾燥部分ＤＰは、室内熱交換器２２において冷媒の流れ方向の下流側に位置する。冷媒は室内熱交換器２２の他の部分を流れている間に温度が上昇するので、乾燥部分ＤＰでは、他の部分に比べて結露が生じにくい（付着する結露水が少ない）。 As a result of such refrigerant flow, a dry portion DP is generated in the upper portion of the second portion 22b of the indoor heat exchanger 22. The dry portion DP is positioned downstream in the refrigerant flow direction in the indoor heat exchanger 22 . Since the temperature of the refrigerant rises while flowing through other parts of the indoor heat exchanger 22, dew condensation is less likely to occur in the dry part DP than in the other parts (there is less condensed water that adheres).
　また、本実施の形態の場合、室内熱交換器２２の乾燥部分ＤＰは、室内熱交換器２２の下方に設けられたドレインパン１４４、１４６から離れた部分であるので、付着している結露水が少ない。すなわち、結露水が室内熱交換器２２の表面上をドレインパン１４４、１４６に向かって下方向に流れるので、室内熱交換器２２の上部に位置する乾燥部分ＤＰには結露水が少ない。 In addition, in the case of the present embodiment, the dry portion DP of the indoor heat exchanger 22 is a portion away from the drain pans 144 and 146 provided below the indoor heat exchanger 22, so the condensed water Less is. That is, since the condensed water flows downward toward the drain pans 144 and 146 on the surface of the indoor heat exchanger 22, the dry portion DP positioned above the indoor heat exchanger 22 has less condensed water.
　このようにノズル１４０から吹き出された室外空気Ａ３が室内機２０内の乾燥領域（本実施の形態の場合、室内熱交換器２２の乾燥部分ＤＰ）を通過してファン２４に向かう理由について説明する。 The reason why the outdoor air A3 blown out from the nozzle 140 in this way passes through the dry area in the indoor unit 20 (in the case of the present embodiment, the dry portion DP of the indoor heat exchanger 22) and goes to the fan 24 will be explained. .
　空気調和機１０は、１つの運転モードとして、冷凍サイクルによる除湿運転（弱冷房運転）と換気装置５０による除湿運転とを同時に実行できるように構成されている。 The air conditioner 10 is configured to be able to simultaneously perform a dehumidifying operation (weak cooling operation) by the refrigeration cycle and a dehumidifying operation by the ventilation device 50 as one operation mode.
　冷凍サイクルによる除湿運転では、ファン２４が回転すると、室内機２０の筺体１４２の上部に設けられた空気取り込み口１４２ａを介して室内空気Ａ１が筺体１４２に取り込まれ、室内熱交換器２２を通過する。このとき、室内空気Ａ１は室内熱交換器２２に冷却されるとともに水分が奪われて乾燥する。奪われた水分は、室内熱交換器２２の表面で結露する。乾燥した室内空気Ａ１は、ファン２４によって空気吹き出し口１４２ｂを介して室内Ｒｉｎに吹き出される。 In the dehumidification operation by the refrigeration cycle, when the fan 24 rotates, the indoor air A1 is taken into the housing 142 through the air intake port 142a provided in the upper part of the housing 142 of the indoor unit 20, and passes through the indoor heat exchanger 22. . At this time, the indoor air A1 is cooled by the indoor heat exchanger 22 and is dehydrated and dried. The removed moisture condenses on the surface of the indoor heat exchanger 22 . The dry indoor air A1 is blown into the room Rin by the fan 24 through the air outlet 142b.
　換気装置５０による除湿運転（図５参照）では、換気装置５０からノズル１４０に、除湿運転における吸着運転時に昇温された室外空気Ａ３が供給される。室外空気Ａ３は、ノズル１４０から吹き出され、ファン２４に誘引されて室内熱交換器２２の乾燥部分ＤＰを通過する。このとき、室外空気Ａ３は、乾燥部分ＤＰを通過するので、すなわち多くの結露水が付着する室内熱交換器２２の他の部分を通過しないので、乾燥状態が維持される。乾燥状態を維持された状態で室内熱交換器２２を通過した室外空気Ａ３は、ファン２４によって空気吹き出し口１４２ｂを介して室内Ｒｉｎに吹き出される。 In the dehumidification operation by the ventilation device 50 (see FIG. 5), the outdoor air A3 heated during the adsorption operation in the dehumidification operation is supplied from the ventilation device 50 to the nozzle 140 . The outdoor air A3 is blown out from the nozzle 140, is attracted by the fan 24, and passes through the dry portion DP of the indoor heat exchanger 22. At this time, the outdoor air A3 passes through the dry portion DP, that is, does not pass through other portions of the indoor heat exchanger 22 where a large amount of condensed water adheres, so that the dry state is maintained. The outdoor air A3 that has passed through the indoor heat exchanger 22 in a dry state is blown out into the room Rin by the fan 24 through the air outlet 142b.
　このような冷凍サイクルによる除湿運転（弱冷房運転）と換気装置５０による除湿運転とを同時に実行すると、室内温度を大きく低下させることなく室内Ｒｉｎを除湿することができる。 Simultaneously executing the dehumidification operation (low cooling operation) by the refrigeration cycle and the dehumidification operation by the ventilation device 50 can dehumidify the room Rin without significantly lowering the room temperature.
　ここで、仮にノズル１４０から吹き出された室外空気Ａ３が、乾燥部分ＤＰ以外の室内熱交換器２２の他の部分を通過すると、その室外空気Ａ３は結露水の蒸発によって加湿される。その加湿された室外空気Ａ３が室内Ｒｉｎに吹き出されるので、すなわち元々室内Ｒｉｎに存在した水分の一部が室内Ｒｉｎに戻ることになるので、室内Ｒｉｎの除湿効率が低下する。 Here, if the outdoor air A3 blown out from the nozzle 140 passes through other parts of the indoor heat exchanger 22 other than the dry part DP, the outdoor air A3 is humidified by evaporation of the condensed water. Since the humidified outdoor air A3 is blown into the room Rin, that is, part of the moisture originally present in the room Rin returns to the room Rin, the dehumidification efficiency of the room Rin decreases.
　また、空気調和機１０は、１つの運転モードとして、冷凍サイクルによる除湿運転（弱冷房運転）と換気装置５０による換気運転とを同時に実行できるように構成されている。 In addition, the air conditioner 10 is configured to be able to simultaneously execute a dehumidifying operation (weak cooling operation) by the refrigeration cycle and a ventilation operation by the ventilator 50 as one operation mode.
　この場合、換気装置５０から除湿されていないそのままの室外空気Ａ３がノズル１４０に供給される。そして、ノズル１４０から吹き出された室外空気Ａ３は、室内熱交換器２２の乾燥部分ＤＰを通過する。この場合、除湿運転によって室内熱交換器２２に付着した結露水の一部を室内Ｒｉｎに戻すことなく、室内Ｒｉｎの換気を行うことができる。 In this case, the outdoor air A3 that is not dehumidified is supplied from the ventilation device 50 to the nozzle 140 as it is. The outdoor air A3 blown out from the nozzle 140 then passes through the dry portion DP of the indoor heat exchanger 22 . In this case, the room Rin can be ventilated without returning part of the dew condensation water adhering to the indoor heat exchanger 22 to the room Rin due to the dehumidifying operation.
　なお、ノズル１４０は、室内機２０内の「乾燥領域」として、室外空気Ａ３の少なくとも一部を室内熱交換器２２とファン２４との間の空間に向かって吹き出してもよい。 Note that the nozzle 140 may blow out at least part of the outdoor air A3 toward the space between the indoor heat exchanger 22 and the fan 24 as a "dry area" inside the indoor unit 20.
　本実施の形態の場合、ノズル１４０は、複数に非破壊で分割可能に構成されている。 In the case of this embodiment, the nozzle 140 is configured to be non-destructively divisible into a plurality of pieces.
　図２８は、ノズル１４０の構成を示す分解斜視図である。また、図２９は、２つに分離された状態のノズル１４０を示す斜視図である。そして、図３０は、ノズル１４０の構成を示す断面図である。 28 is an exploded perspective view showing the configuration of the nozzle 140. FIG. FIG. 29 is a perspective view showing the nozzle 140 separated into two. 30 is a cross-sectional view showing the structure of the nozzle 140. As shown in FIG.
　図２８に示すように、ノズル１４０は、４つの部品１４８、１５０、１５２および１５４から構成されている。具体的には、図２９に示すように、本実施の形態の場合、ノズル１４０は、接続部１４０ａを備える後側部分１４０ｃと、吹き出し口１４０ｂを備える前側部分１４０ｄに分離可能に構成されている。後側部分１４０ｃは前側部分１４０ｄと接続するための接続口１４０ｅを備え、前側部分１４０ｄの先端部１４０ｆが接続口１４０ｅに抜き差し可能に挿入される。 As shown in FIG. 28, the nozzle 140 consists of four parts 148, 150, 152 and 154. Specifically, as shown in FIG. 29, in the case of the present embodiment, the nozzle 140 is configured to be separable into a rear portion 140c having a connecting portion 140a and a front portion 140d having an outlet 140b. . The rear portion 140c has a connection port 140e for connecting with the front portion 140d, and the front end portion 140f of the front portion 140d is removably inserted into the connection port 140e.
　図２９に示すように、本実施の形態の場合、後側部分１４０ｃは室内機２０のベース部材１５６に取り付けられており、前側部分１４０ｄはフィルタ枠１５８に取り付けられている。ベース部材１５６は、室内機２０を壁面に据え付けるときのブラケットとして機能するとともに、室内熱交換器２２やファン２４などの室内機２０の構成要素を保持する。フィルタ枠１５８は、室内熱交換器２２に向かう室内空気Ａ１が通過するフィルタ（図示せず）を保持する部材であって、ベース部材１５６に対して取り外し可能に構成されている。フィルタ枠１５８をベース部材１５６から取り外すと、ノズル１４０の後側部分１４０ｃから前側部分１４０ｄが分離する。 As shown in FIG. 29, in this embodiment, the rear portion 140c is attached to the base member 156 of the indoor unit 20, and the front portion 140d is attached to the filter frame 158. The base member 156 functions as a bracket when installing the indoor unit 20 on the wall surface, and also holds components of the indoor unit 20 such as the indoor heat exchanger 22 and the fan 24 . The filter frame 158 is a member that holds a filter (not shown) through which the indoor air A1 directed toward the indoor heat exchanger 22 passes, and is configured to be removable from the base member 156 . Removing the filter frame 158 from the base member 156 separates the front portion 140 d from the rear portion 140 c of the nozzle 140 .
　図３０に示すように、ノズル１４０の後側部分１４０ｃの接続口１４０ｅに前側部分１４０ｄの先端部１４０ｆが挿入されると、後側部分１４０ｃの内周面１４０ｇと前側部分１４０ｄの内周面１４０ｈが段差なく連続するように接続する。これにより、後側部分１４０ｃから前側部分１４０ｄに流れる室外空気Ａ３の圧力損失が抑制されている。 As shown in FIG. 30, when the front end portion 140f of the front portion 140d is inserted into the connection port 140e of the rear portion 140c of the nozzle 140, the inner peripheral surface 140g of the rear portion 140c and the inner peripheral surface 140h of the front portion 140d are separated. connected so that they are continuous without steps. This suppresses the pressure loss of the outdoor air A3 flowing from the rear portion 140c to the front portion 140d.
　図２８に示すように、ノズル１４０の後側部分１４０ｃは、その内部流路に沿って２つの部品１４８、１５０に分割可能に構成されている。また、前側部分１４０ｄも、その内部流路に沿って２つの部品１５２、１５４に分割可能に構成されている。なお、部品１４８、１５０は、ねじなどの固定部品を使用することなく、例えばスナップ係合などにより合体可能に構成されている。同様に、部品１５２、１５４も、固定部品を使用することなく合体可能に構成されている。 As shown in FIG. 28, the rear portion 140c of the nozzle 140 is configured to be splittable into two parts 148, 150 along its internal flow path. The front portion 140d is also configured to be splittable into two parts 152, 154 along its internal flow path. Note that the parts 148 and 150 are configured to be able to be joined together by, for example, snap engagement without using fixing parts such as screws. Similarly, parts 152, 154 are also configured to be dockable without the use of securing parts.
　なお、図３０に示すように、本実施の形態の場合、ノズル１４０の後側部分１４０ｃには、流路断面積を他の場所に比べて小さくする縮流部１４０ｉが設けられている。これにより、室外機３０からの騒音を反射し、室内機２０内に伝わる騒音のレベルを低下させることができる。 In addition, as shown in FIG. 30, in the case of the present embodiment, the rear portion 140c of the nozzle 140 is provided with a constriction portion 140i that makes the cross-sectional area of the flow passage smaller than that of other locations. As a result, the noise from the outdoor unit 30 can be reflected, and the level of noise transmitted inside the indoor unit 20 can be reduced.
　このような構成のノズル１４０によれば、その内部のチェックやクリーニングを容易に行うことができる。すなわち、ノズル１４０を４つの部品１４８、１５０、１５２および１５４に分割し、それぞれの部品に対してチェックやクリーニングを行うことができる。 According to the nozzle 140 having such a configuration, it is possible to easily check and clean the inside. That is, the nozzle 140 can be divided into four parts 148, 150, 152 and 154, each of which can be checked or cleaned.
　以上のような本実施の形態によれば、室外空気Ａ３が回転する吸収材５２を通過することによって加湿されて室内機２０に供給される空気調和機１０において、室外空気Ａ３が吸収材５２をバイパスすることを抑制することができる。 According to the present embodiment as described above, in the air conditioner 10 in which the outdoor air A3 is humidified by passing through the rotating absorbent 52 and supplied to the indoor unit 20, the outdoor air A3 passes through the absorbent 52. Bypassing can be suppressed.
　以上、上述の実施の形態を挙げて本開示を説明したが、本開示は上述の実施の形態に限定されない。 Although the present disclosure has been described with reference to the above-described embodiments, the present disclosure is not limited to the above-described embodiments.
　例えば、上述の実施の形態の場合、図１９に示すように、吸収材ホルダ１１４は、スムーズに回転するために、対向部材（ヒータベース部材１１２の吸収材収容部１１２ｂおよび仕切り板１２４）と接触していない。しかしながら、本開示の実施の形態はこれに限らない。吸収材ホルダ１１４は、回転可能であれば、一部分が対向部材に対して摺動してもよい。 For example, in the case of the above embodiment, as shown in FIG. 19, the absorbent holder 114 is in contact with the facing member (the absorbent housing portion 112b of the heater base member 112 and the partition plate 124) in order to rotate smoothly. not. However, embodiments of the present disclosure are not limited to this. If the absorbent holder 114 is rotatable, a portion of the absorbent holder 114 may slide relative to the opposing member.
　すなわち、本開示の実施の形態に係る空気調和機は、広義には、室内機と室外機とを有する空気調和機である。そして、室外機が、室外空気を加熱するヒータと、第１の端面と第２の端面とを備え、ヒータによって加熱された室外空気が第１の端面から第２の端面に向かって通過する円盤状の吸収材と、を備える。また、室外機が、吸収材の外周面を保持する円筒状部を備えて回転する吸収材ホルダと、吸収材ホルダの外周面に対して対向する対向部材と、を備える。また、室外機が、吸収材を通過する室外空気の流れを発生させるファンと、吸収材ホルダの外周面と対向部材との間に、ラビリンス流路を形成するラビリンスシール部材と、を備える。そして、吸収材ホルダが、拡径部を含み、ラビリンスシール部材が、ラビリンス流路の一部分として、吸収材ホルダの拡径部との間に吸収材の径方向に少なくとも延在する径方向流路を形成する端面を備える。 That is, in a broad sense, the air conditioner according to the embodiment of the present disclosure is an air conditioner having an indoor unit and an outdoor unit.
