加湿ユニット、および空気調和機の室外機  Humidification unit and outdoor unit of air conditioner
技術分野  Technical field
[0001] 本発明は、室外に配置され、ダクトを介して室内に加湿空気を送る加湿ユニット、お よび空気調和機の室外機に関する。  TECHNICAL FIELD [0001] The present invention relates to a humidifying unit that is arranged outside and sends humidified air into a room via a duct, and an outdoor unit of an air conditioner.
背景技術  Background art
[0002] 従来より、吸着材を用いた無給水の加湿装置が知られて!/、る。特許文献 1記載の 加湿装置は、吸着材を含む回転ロータと、吸着ファンと、加湿ファンと、ヒータとを備 えている。  [0002] Conventionally, a humidifier without water supply using an adsorbent has been known! The humidifier described in Patent Document 1 includes a rotary rotor including an adsorbent, an adsorption fan, a humidification fan, and a heater.
回転ロータがその円板状表面の中心回りに回転することによって、円板状表面は 除湿側（吸着側)通路および再生側 (脱離側)通路を順に通過する。除湿側通路に は、吸着ファンが配置され、再生側通路には、加湿ファンが配置されている。  As the rotating rotor rotates around the center of the disk-shaped surface, the disk-shaped surface passes through the dehumidification side (adsorption side) passage and the regeneration side (desorption side) passage in order. An adsorption fan is disposed in the dehumidification side passage, and a humidification fan is disposed in the regeneration side passage.
回転ロータの円板状表面の一部が除湿側通路を通過するとき、吸着ファンによって 吸着用室外空気が吸着材へ供給される。このとき、吸着用室外空気に含まれる水分 は、吸着材に吸着される。  When a part of the disk-shaped surface of the rotating rotor passes through the dehumidifying side passage, the outdoor air for adsorption is supplied to the adsorbent by the adsorption fan. At this time, moisture contained in the outdoor air for adsorption is adsorbed by the adsorbent.
一方、回転ロータの円板状表面の一部が再生側通路を通過するとき、ヒータによつ て加熱された脱離用室外空気が、加湿ファンによって吸着材に供給される。吸着材 が脱離用室外空気の熱によって加熱されることによって、吸着材から水分が脱離す る。その結果、脱離用室外空気と吸着材から脱離された水分とが混合されることによ つて、加湿空気が生成される。加湿空気は、空気ダクトの内部を流れて室内に導か れる。  On the other hand, when a part of the disk-shaped surface of the rotary rotor passes through the regeneration side passage, the outdoor air for desorption heated by the heater is supplied to the adsorbent by the humidifying fan. When the adsorbent is heated by the heat of the outdoor air for desorption, moisture is desorbed from the adsorbent. As a result, humidified air is generated by mixing the outdoor air for desorption and the water desorbed from the adsorbent. The humidified air flows through the air duct and is guided into the room.

Further, such a heater cannot directly heat the adsorbent. Therefore, he Taka The adsorbent cannot be heated quickly due to the heat generated.

〔第 4実施形態〕 [Fourth embodiment]
<第 4実施形態の背景 > <Background of the fourth embodiment>
特許文献 1記載の加湿装置では、吸着材へ水分を吸着させるために、外気から空 気を取り込んで吸着材へ送っている。吸着材は、吸着材へ送られる空気の温度が低 V、ほど吸着材に水分が吸着する度合 、である吸着効率が向上する性質を有して 、 る。したがって、吸着材へ送られる空気の温度が低い方が好ましい。  In the humidifier described in Patent Document 1, in order to adsorb moisture to the adsorbent, air is taken from outside air and sent to the adsorbent. The adsorbent has the property of improving the adsorption efficiency, which is the degree to which moisture is adsorbed by the adsorbent as the temperature of the air sent to the adsorbent becomes lower. Therefore, it is preferable that the temperature of the air sent to the adsorbent is lower.
一方、空気調和機が暖房運転中のときには、室外機の室外熱交換器内部の冷媒 が膨張して室外熱交 を通過する空気力も熱を奪うため、室外熱交 を通過す る空気は、室外空気よりも低温になる。そこで、暖房運転中の室外熱交 を通過し て冷却される空気を加湿装置の吸着材へ送れば、室外空気を送るよりも、吸着効率 が向上すると考えられる。  On the other hand, when the air conditioner is in the heating operation, the refrigerant inside the outdoor heat exchanger of the outdoor unit expands and the aerodynamic force passing through the outdoor heat exchange also takes heat, so the air passing through the outdoor heat exchange It becomes cooler than air. Therefore, it is considered that if the air cooled through the outdoor heat exchange during the heating operation is sent to the adsorbent of the humidifier, the adsorption efficiency will be improved compared to sending the outdoor air.
しかし、室外空気が低温になると、暖房運転中の室外熱交換器の表面温度が室外 空気よりもさらに低温になって室外熱交 を通過する空気力 室外熱交^^の表 面に湿気を奪う温度になることがある。このとき、室外熱交換器の表面に湿気を奪わ れて乾燥した空気を吸着材へ送ることになつてしま 、、力えって吸着効率が低下する という問題がある。 However, when the outdoor air temperature becomes low, the surface temperature of the outdoor heat exchanger during heating operation becomes even lower than that of the outdoor air and passes through the outdoor heat exchange. The surface may be deprived of moisture. At this time, moisture is deprived from the surface of the outdoor heat exchanger and the dried air is sent to the adsorbent, which causes a problem that the adsorption efficiency is lowered.
そこで、第 4実施形態では、吸着効率の低下を抑制することができる加湿ユニットを 提供する。  Therefore, the fourth embodiment provides a humidification unit that can suppress a decrease in adsorption efficiency.
<第 4実施形態の概要 >  <Outline of the fourth embodiment>

The air flow adjusting unit adjusts the ratio of the air flow in the first air flow path and the air flow in the second air flow path. When there is a possibility that moisture may be deprived from the air flow in the second air flow path to the surface of the outdoor heat exchanger, the control unit causes the air flow in the second air flow path to be more than the air flow in the first air flow path. The air flow adjusting unit is adjusted so as to be relatively small.
ここでは、第 2空気流路の空気流れから室外熱交換器の表面に湿気が奪われる可 能性があるときに、第 2空気流路の空気流れを第 1空気流路の空気流れよりも相対的 に少なくするように、空気流れ調整部が制御部によって調整されるので、吸着効率の 低下を抑制することが可能である。  Here, when there is a possibility that moisture is deprived from the air flow in the second air flow path to the surface of the outdoor heat exchanger, the air flow in the second air flow path is more than the air flow in the first air flow path. Since the air flow adjustment unit is adjusted by the control unit so as to be relatively small, it is possible to suppress a decrease in adsorption efficiency.

ここでは、室外熱交換器の温度が室外熱交換器の表面に湿気が奪われる可能性 力 Sある所定の第 1温度しきい値に以下になったときに、第 2空気流路の空気流れを第 1空気流路の空気流れよりも相対的に少なくするように、空気流れ調整部が制御部に よって調整されるので、吸着効率の低下を抑制することが可能である。 [0027] また、第 4実施形態の加湿ユニットは、第 2温度検出部をさらに備えている。第 2温 度検出部は、外気の温度を検出する。制御部は、外気の温度が室外熱交換器の表 面に湿気が奪われる可能性がある所定の第 2温度しきい値に以下になったときに、 第 2空気流路の空気流れを第 1空気流路の空気流れよりも相対的に少なくするように 、空気流れ調整部を調整する。 Here, the temperature of the outdoor heat exchanger may be deprived of moisture on the surface of the outdoor heat exchanger.Force S The air flow in the second air flow path when the temperature falls below a certain first temperature threshold value. Since the air flow adjusting unit is adjusted by the control unit so as to be relatively less than the air flow in the first air flow path, it is possible to suppress a decrease in adsorption efficiency. [0027] The humidification unit of the fourth embodiment further includes a second temperature detection unit. The second temperature detector detects the temperature of the outside air. The control unit controls the air flow in the second air flow path when the temperature of the outside air falls below a predetermined second temperature threshold that may cause moisture to be removed from the surface of the outdoor heat exchanger. 1Adjust the air flow adjustment section so that it is relatively less than the air flow in the air flow path.

Since the air flow adjustment unit is adjusted by the control unit so as to be relatively less than the air flow in the flow path, it is possible to suppress a decrease in adsorption efficiency.

The first temperature detector detects the temperature of the outdoor heat exchanger. The second temperature detector detects the temperature of the outside air. When the temperature of the outdoor heat exchanger falls below a predetermined first temperature threshold at which moisture may be deprived from the surface of the outdoor heat exchanger, or the temperature of the outdoor air The air flow in the second air flow path is changed to the first air when one of the conditions occurs when the temperature falls below the predetermined second temperature threshold that can cause moisture to be deprived from the surface of the exchanger. Adjust the air flow adjuster so that it is relatively less than the air flow in the flow path.
[0028] ここでは、制御部は、室外熱交換器の温度および外気温度の両方の温度に基づい て、空気流れ調整部を調整する。すなわち、室外熱交換器の温度が室外熱交換器 の表面に湿気が奪われる可能性がある所定の第 1温度しきい値に以下になったとき 、または外気の温度が室外熱交換器の表面に湿気が奪われる可能性がある所定の 第 2温度しきい値に以下になったときのいずれかの状態になったときに、第 2空気流 路の空気流れを第 1空気流路の空気流れよりも相対的に少なくするように、空気流れ 調整部が制御部によって調整される。これにより、吸着効率の低下を抑制することが 可能である。  Here, the control unit adjusts the air flow adjusting unit based on both the temperature of the outdoor heat exchanger and the outside air temperature. That is, when the temperature of the outdoor heat exchanger falls below a predetermined first temperature threshold at which moisture may be deprived from the surface of the outdoor heat exchanger, or when the temperature of the outdoor air is below the surface of the outdoor heat exchanger The air flow in the second air flow path is changed to the air flow in the first air flow path when any of the conditions below when the predetermined second temperature threshold value is reached. The air flow adjusting unit is adjusted by the control unit so as to be relatively less than the flow. Thereby, it is possible to suppress a decrease in adsorption efficiency.

制御部 131は、第 2空気流路 150の空気流れから室外熱交換器 121の表面に湿 気が奪われる可能性があるときに、第 2空気流路 150の空気流れを第 1空気流路 14 0の空気流れよりも相対的に少なくするように、ダンバ 113を調整する。具体的には、 制御部 131は、室外熱交換器 121の温度 θ 1および外気温度 Θ 2の両方の温度に 基づいて、ダンバ 113を調整する。すなわち、制御部 131によって、室外熱交換器 1 21の温度 θ 1が室外熱交換器 121の表面に湿気が奪われる可能性がある所定の第 1温度しきい値 δ 1以下になったとき、または外気の温度 Θ 2が室外熱交換器 121の 表面に湿気が奪われる可能性がある所定の第 2温度しきい値 δ 2以下になったとき のいずれかの状態になったときに、第 2空気流路 150の空気流れを第 1空気流路 14 0の空気流れよりも相対的に少なくするように、ダンバ 113が調整される。これにより、 吸着効率の低下を抑制することが可能である。  When there is a possibility that moisture may be deprived from the air flow in the second air flow path 150 to the surface of the outdoor heat exchanger 121, the control unit 131 changes the air flow in the second air flow path 150 to the first air flow path. The damper 113 is adjusted so that it is relatively less than the air flow of 140. Specifically, the control unit 131 adjusts the damper 113 based on both the temperature θ 1 and the outside air temperature Θ 2 of the outdoor heat exchanger 121. That is, when the control unit 131 causes the temperature θ 1 of the outdoor heat exchanger 121 to become equal to or lower than a predetermined first temperature threshold value δ 1 where moisture may be deprived from the surface of the outdoor heat exchanger 121. Or when the temperature of the outdoor air Θ2 reaches any of the following conditions when the temperature of the outdoor heat exchanger 121 falls below a predetermined second temperature threshold value δ2 that may cause moisture to be removed: The damper 113 is adjusted so that the air flow in the two air flow paths 150 is relatively less than the air flow in the first air flow path 140. Thereby, it is possible to suppress a decrease in adsorption efficiency.
く吸着材 104の構成〉  <Configuration of Adsorbent 104>
吸着材 104は、ハ-カム状に形成された基材の表面に吸着剤を担持させることによ つて製造されている。基材としては、比熱の小さい材料、例えば、セラミック紙、ガラス 繊維、セルロースを主成分とした有機化合物 (例えば、紙)、金属、榭脂等の材料が 好適に用いられる。吸着剤は、吸着性能と脱離性能の両方の特性を有する材料、例 えば、疎水性ゼォライトなどが好適に用いられる。  The adsorbent 104 is manufactured by supporting an adsorbent on the surface of a base material formed in a her cam shape. As the substrate, materials having a small specific heat, such as ceramic paper, glass fiber, organic compounds mainly composed of cellulose (for example, paper), metals, and resin are preferably used. As the adsorbent, a material having characteristics of both adsorption performance and desorption performance, such as hydrophobic zeolite, is preferably used.
[0034] 吸着材 104は、ヒータカバー 106とともに閉空間形成部材となる。また、吸着材 104 は、通気性を有する。吸着材 104から脱離された水分は、吸着材 104を通過して円 滑に閉空間 111の外へ排出される。吸着材 104を通過した空気は、空気流路 112を 介してファン 107へ向力う。 The adsorbent 104 becomes a closed space forming member together with the heater cover 106. Moreover, the adsorbent 104 has air permeability. Moisture desorbed from the adsorbent 104 passes through the adsorbent 104 and is smoothly discharged out of the closed space 111. The air that has passed through the adsorbent 104 is directed to the fan 107 via the air flow path 112.
また、吸着材 104は、細長い矩形形状を呈している。吸着材 104は、図 15に示され るように、空気流れの下流側に位置する第 1の端部 104b、および第 1の端部 104bに 対向する第 2の端部 104cを有している。ファン 107の吸気口 107aは、空気流路 112 に接続されている。吸気口 107aは、吸着材 104の第 1の端部 104bの近傍に配置さ れている。吸着材 104は、ファン 107から吸着材 104の第 2の端部 104cまでの距離 に基づ!/、て吸気具合を変えるように製造されて 、る。 Further, the adsorbent 104 has an elongated rectangular shape. The adsorbent 104 is shown in FIG. As shown, the first end portion 104b located on the downstream side of the air flow and the second end portion 104c facing the first end portion 104b are provided. The air inlet 107 a of the fan 107 is connected to the air flow path 112. The air inlet 107a is disposed in the vicinity of the first end 104b of the adsorbent 104. The adsorbent 104 is manufactured based on the distance from the fan 107 to the second end 104c of the adsorbent 104 so as to change the intake condition.
<フィルタ 104aの構成 > <Configuration of filter 104a>
図 12および図 16に示されるように、吸着材 104の一部は、閉空間 111に導入され る空気を濾過するフィルタ 104aになっている。フィルタ 104aは、図 16に示されるよう に、吸着材 104のうち、空気流路 112よりも両側にはみ出ている部分である。したが つて、フィルタ 104aは、ヒータカバー 106および吸着材 104とともに閉空間形成部材 となっている。これにより、閉空間 111に導入される空気の清浄度を上げることができ る。  As shown in FIGS. 12 and 16, a part of the adsorbent 104 is a filter 104a that filters the air introduced into the closed space 111. As shown in FIG. 16, the filter 104a is a portion of the adsorbent 104 that protrudes on both sides of the air flow path 112. Therefore, the filter 104 a is a closed space forming member together with the heater cover 106 and the adsorbent 104. Thereby, the cleanliness of the air introduced into the closed space 111 can be increased.
<ファン 107の構成 >  <Composition of fan 107>
ファン 107は、図 16に示されるように、吸着材 104の吸着および脱離のための空気 を吸着材 104へ供給する。  The fan 107 supplies air for adsorption and desorption of the adsorbent 104 to the adsorbent 104 as shown in FIG.

ファンケーシング 173は、スクロール形状を有するスクロールケーシングであり、下 面側にファン 107の吸気口 107aが形成され、側部にファン 107の排気口 107bが形 成されている。また、ファンケーシング 173の上面側には、ディフューザ 174によって 開閉される開口 107cが形成されている。  The fan casing 173 is a scroll casing having a scroll shape, and an air inlet 107a of the fan 107 is formed on the lower side, and an air outlet 107b of the fan 107 is formed on the side. An opening 107 c that is opened and closed by the diffuser 174 is formed on the upper surface side of the fan casing 173.
ディフューザ 174は、ファンケーシング 173の上面側の開口 107cを覆うように設け られている。ディフューザ 174は、ディフューザ駆動部 175によって、回転軸 172aの 延びる方向に沿って往復移動することにより、開口 107cを開閉することが可能である 。ディフューザ 174は、ディフューザ駆動部 175に内蔵された図示されないステツピン グモータの駆動力によって上下方向に開閉される。 The diffuser 174 is provided so as to cover the opening 107c on the upper surface side of the fan casing 173. The diffuser 174 can open and close the opening 107c by reciprocating along the direction in which the rotating shaft 172a extends by the diffuser driving unit 175. The diffuser 174 is a step pin (not shown) built in the diffuser driving unit 175. It is opened and closed in the vertical direction by the driving force of the motor.
また、ディフューザ 174の周縁部には、ディフューザ 174を閉めたときにディフュー ザ 174とファンケーシング 173との隙間力も空気が洩れないように、発泡ゴムなどから なるシール材 176が設けられている。  In addition, a seal member 176 made of foam rubber or the like is provided at the peripheral edge of the diffuser 174 so that air does not leak even when the gap between the diffuser 174 and the fan casing 173 is closed when the diffuser 174 is closed.
ファン 107は、吸着材 104の吸着時および脱離時それぞれにおいて回転数が異な るようにファンロータ 171が回転するように設定されている。  The fan 107 is set so that the fan rotor 171 rotates so that the number of rotations is different when the adsorbent 104 is adsorbed and desorbed.
吸着材 104の吸着時におけるファン 107による吸込圧力は、空気流路 123において 室外熱交 l21から吸着材 104へ向力 空気流れが発生することが可能な吸込 圧力に設定される。 The suction pressure by the fan 107 when the adsorbent 104 is adsorbed is set to a suction pressure at which an air flow can be generated from the outdoor heat exchanger l21 to the adsorbent 104 in the air flow path 123.
<加湿ユニット 102の動作手順 > <Operation procedure of humidification unit 102>
加湿ユニット 102は、吸着動作および加湿動作を交互に行うバッチ運転を行う。 〇吸着動作  The humidification unit 102 performs a batch operation in which an adsorption operation and a humidification operation are alternately performed. ○ Adsorption operation
吸着動作のときには、ファン 107で室外空気を取り込み、水分を吸着材 104に吸着さ せる。このとき、加湿ユニット 102の各構成要素は、以下のような状態になる。 During the adsorption operation, outdoor air is taken in by the fan 107 and moisture is adsorbed by the adsorbent 104. At this time, each component of the humidifying unit 102 is in the following state.
•吸加湿用のファン 107の回転は、水分を吸着材 104に吸着させるのに適した低静 圧大風量を得るために低回転である。  • The rotation of the fan 107 for humidifying and humidifying is low in order to obtain a low static pressure and large air volume suitable for adsorbing moisture on the adsorbent 104.

•ディフューザ 174は、低静圧大風量を得るために開口 107c (図 16参照）を開放す るために開いている。したがって、開放された開口 107cから出た吸着排気 F3 (図 14 参照）の一部は、遠心方向に吹き出す。  • Diffuser 174 is open to open opening 107c (see Figure 16) to obtain low static pressure and high air flow. Therefore, a part of the adsorbed exhaust F3 (see FIG. 14) exiting from the opened opening 107c is blown out in the centrifugal direction.
•ルーパダンパ 109は、吸着材 104を通過した吸着排気 F3の残りを排気口 110a (図 13参照）力 室外へ排出するために開 ヽて 、る。  • The looper damper 109 is opened to discharge the remainder of the adsorbed exhaust F3 that has passed through the adsorbent 104 to the exhaust port 110a (see Fig. 13).
〇加湿動作 〇 Humidification operation
加湿動作のときには、吸着材 104をヒータ 105で加熱して水分を脱離させ、ファン 1 07によって吸い込む。加湿空気は、ファン 107によってダクト 108を介して空気調和 機の室内機（図示せず)へ送り込まれる。  During the humidification operation, the adsorbent 104 is heated by the heater 105 to desorb moisture and sucked by the fan 107. The humidified air is sent to the indoor unit (not shown) of the air conditioner through the duct 108 by the fan 107.
このとき、加湿ユニット 102の各構成要素は、以下のような状態になる。 At this time, each component of the humidifying unit 102 is in the following state.
•ファン 107の回転は、水分を吸着材 104から脱離させるのに適した高静圧小風量を 得るために高回転である。 • The rotation of the fan 107 produces a high static pressure and low air volume suitable for desorbing moisture from the adsorbent 104. High rotation to get.
•ヒータ 105は、通電されている。したがって、吸着材 104はヒータ 105によって加熱さ れる。  • The heater 105 is energized. Therefore, the adsorbent 104 is heated by the heater 105.

<図 14および図 15を用いた空気流れの説明 >  <Explanation of air flow using Fig. 14 and Fig. 15>
図 14および図 15に示されるように、ケーシング 110の内部に導入される空気である 吸気 F1および室外熱交通過空気 FAは、まず、吸着材 104の両端部であるフィルタ 104aから閉空間 111の内部に下方力も導入される。  As shown in FIG. 14 and FIG. 15, the intake air F1 and the outdoor heat exchange passing air FA, which are air introduced into the casing 110, first pass from the filter 104a, which is both ends of the adsorbent 104, into the closed space 111. A downward force is also introduced inside.
[0037] ついで、閉空間 111に導入された空気は、通気性を有する吸着材 104を通過して 空気流路 112に進む（吸着材通過空気 F2参照)。 [0037] Next, the air introduced into the closed space 111 passes through the adsorbent 104 having air permeability and proceeds to the air flow path 112 (see adsorbent passing air F2).
そののち、吸着材通過空気 F2は、空気流路 112を通って吸着材 104の下流側の 第 1の端部 104bに配置されたファン 107の吸気口 107aを通してファン 107の内部 に導入される。  After that, the adsorbent passing air F2 is introduced into the fan 107 through the air passage 112 and through the air inlet 107a of the fan 107 disposed at the first end 104b on the downstream side of the adsorbent 104.
そののち、吸着動作の場合には、ディフューザ 174およびルーパダンパ 109が開い ているので、吸着排気 F3として開口 107cから遠心方向に外部へ吹き出すとともに排 気口 107bから室外へ吹き出す。  After that, in the case of the adsorption operation, the diffuser 174 and the looper damper 109 are open, and therefore, the adsorption exhaust F3 is blown out in the centrifugal direction from the opening 107c and blown out through the exhaust port 107b.
また、加湿動作の場合には、ディフューザ 174およびルーパダンパ 109が閉じている ので、加湿空気 F4として排気口 107b力もダクト 108を介して室内へ送られる。  Further, in the humidifying operation, since the diffuser 174 and the looper damper 109 are closed, the exhaust port 107b force is also sent to the room through the duct 108 as the humidified air F4.
<ダンバ 113による空気流れの調整方法の説明 >  <Explanation of how air flow is adjusted by damper 113>
つぎに、加湿ユニット 102におけるダンバ 113による空気流れの調整方法を、図 17 のダンバ制御系のブロック図および図 18のフローチャートを用いて説明する。  Next, a method of adjusting the air flow by the damper 113 in the humidifying unit 102 will be described using the block diagram of the damper control system in FIG. 17 and the flowchart in FIG.
[0038] まず、ステップ S1において、制御部 131は、第 1温度検出部 114で測定される室外 熱交換器 121の温度 0 1 (図 18における室外熱交温度 0 1)が室外熱交換器 121の 表面に霜が付いたり、結露するなどして湿気が奪われる可能性がある所定の第 1温 度しきい値 δ 1以下になる力否かを判定する。 Θ 1が δ 1以下になる場合には、ステツ プ S3へ進み、そうでないときは、ステップ S2へ進む。 さらに、ステップ S2において、制御部 131は、第 2温度検出部 115で測定される外 気の温度 Θ 2 (図 18における外気温度 Θ 2)が室外熱交換器 121の表面に霜が付い たり、結露するなどして湿気が奪われる可能性がある所定の第 2温度しきい値 δ 2以 下になる力否かを判定する。 Θ 2が δ 2以下になる場合には、ステップ S3へ進み、そ うでないときは、ステップ S4へ進む。 First, in step S1, the controller 131 determines that the temperature 0 1 of the outdoor heat exchanger 121 (outdoor heat exchange temperature 0 1 in FIG. 18) measured by the first temperature detector 114 is the outdoor heat exchanger 121. It is judged whether or not the force is below a predetermined first temperature threshold value δ 1 that may cause moisture to be removed due to frost or dew condensation on the surface. If Θ1 is less than or equal to δ1, proceed to step S3, otherwise proceed to step S2. Further, in step S2, the controller 131 detects that the temperature Θ 2 of the outside air measured by the second temperature detector 115 (outside temperature Θ 2 in FIG. 18) is frosted on the surface of the outdoor heat exchanger 121, It is determined whether or not the force falls below a predetermined second temperature threshold value δ 2 where moisture may be deprived due to condensation. If Θ2 is equal to or less than δ2, the process proceeds to step S3. Otherwise, the process proceeds to step S4.
[0039] 上記のように θ 1が δ 1以下になる力 または Θ 2が δ 2以下になるかのいずれかの 場合には、ステップ S3において、ダンバ 113を閉じて室外熱交換器 121を通過した 空気 FAが吸着材 104へ向力 空気流れを遮断することにより、第 2空気流路 150の 空気流れを第 1空気流路 140の空気流れよりも相対的に少なくする。これにより、吸 着効率の低下を抑制することが可能である。  [0039] As described above, when either θ 1 is less than δ 1 or Θ 2 is less than δ 2, in step S3, the damper 113 is closed and the outdoor heat exchanger 121 is passed. The air FA is directed toward the adsorbent 104. By blocking the air flow, the air flow in the second air flow path 150 is relatively less than the air flow in the first air flow path 140. Thereby, it is possible to suppress a decrease in adsorption efficiency.
一方、 θ 1力 S δ 1より大きく、かつ Θ 2力 S δ 2より大き!/、場合に ίま、ステップ S4にお!/、 て、ダンバ 113を開けて室外熱交換器 121を通過した空気 F Αが吸着材 104へ向か う空気流れを許容する。これにより、外気温度よりも低ぐかつ、室外熱交換器 121〖こ 湿気が奪われな 、温度の空気 FAを吸着材 104へ供給することができ、吸着効率を 向上することが可能である。  On the other hand, greater than θ 1 force S δ 1 and greater than Θ 2 force S δ 2! /, In some cases, in step S4, the damper 113 was opened and passed through the outdoor heat exchanger 121. Air F Α allows air flow to adsorbent 104. As a result, air FA at a temperature lower than the outside air temperature and without being deprived of the humidity of the outdoor heat exchanger 121 can be supplied to the adsorbent 104, and the adsorption efficiency can be improved.
[0040] 第 4実施形態の加湿ユニット 102は、吸着材をヒータによって加熱する加湿ユニット 、およびその加湿ユニットを備えた空気調和機の室外機に利用することが可能である  The humidification unit 102 of the fourth embodiment can be used for a humidification unit that heats the adsorbent with a heater and an outdoor unit of an air conditioner that includes the humidification unit.

(1)  (1)
加湿ユニット 102では、制御部 131は、第 2空気流路 150の空気流れから室外熱交 121の表面に湿気が奪われる可能性があるときに、第 2空気流路 150の空気流 れを第 1空気流路 140の空気流れよりも相対的に少なくするように、ダンバ 113を調 整するので、吸着効率の低下を抑制することが可能である。  In the humidification unit 102, the control unit 131 changes the air flow in the second air flow path 150 when there is a possibility that moisture is deprived from the air flow in the second air flow path 150 to the surface of the outdoor heat exchanger 121. Since the damper 113 is adjusted so as to be relatively less than the air flow in the one air flow path 140, it is possible to suppress a decrease in adsorption efficiency.

さらに詳しくは、加湿ユニット 102では、制御部 131は、室外熱交^^ 121の温度 および外気温度の両方の温度に基づいて、ダンバ 113を調整する。すなわち、制御 部 131は、室外熱交換器 121の温度 0 1が室外熱交換器 121の表面に湿気が奪わ れる可能性がある所定の第 1温度しきい値 δ 1に以下になったとき、または外気の温 度 Θ 2が室外熱交換器 121の表面に湿気が奪われる可能性がある所定の第 2温度 しきい値 δ 2以下になったときのいずれかの状態になったときに、第 2空気流路 150 の空気流れを第 1空気流路 140の空気流れよりも相対的に少なくするように、ダンバ 113を調整する。これにより、吸着効率の低下を抑制することが可能である。 More specifically, in the humidification unit 102, the control unit 131 adjusts the damper 113 based on both the temperature of the outdoor heat exchanger 121 and the outside air temperature. That is, the control unit 131 causes the temperature 01 of the outdoor heat exchanger 121 to remove moisture from the surface of the outdoor heat exchanger 121. When the predetermined first temperature threshold δ 1 falls below or when the outside air temperature Θ 2 is deprived of moisture on the surface of the outdoor heat exchanger 121 The temperature of the second air flow path 150 is set to be relatively less than the air flow of the first air flow path 140 when any of the temperature threshold values δ 2 or less is reached. Adjust the damper 113. Thereby, it is possible to suppress a decrease in adsorption efficiency.

加湿ユニット 102では、ダンバ 113が第 2空気流路 150を開閉することによって、第 2空気流路 150の空気流れを第 1空気流路 140の空気流れよりも相対的に少なくす るように調整することができ、吸着効率の低下を抑制することが可能である。  In the humidification unit 102, the damper 113 is adjusted to open and close the second air flow path 150 so that the air flow in the second air flow path 150 is relatively less than the air flow in the first air flow path 140. It is possible to suppress a decrease in adsorption efficiency.

加湿ユニット 102では、吸着材 104の吸着および脱離の動作を交互に行うバッチ運 転が可能であり、バッチ運転の場合であっても、室外熱交換器を通過した空気を用 いて吸着材に水分を吸着することが可能であり、し力も、吸着効率の低下を抑制する ことが可能である。  The humidifying unit 102 can perform batch operation in which adsorption and desorption operations of the adsorbent 104 are alternately performed. Even in the case of batch operation, the air that has passed through the outdoor heat exchanger is used as the adsorbent. It is possible to adsorb moisture, and the force can also suppress a decrease in adsorption efficiency.
<第 4実施形態の変形例 > <Modification of the fourth embodiment>
(Α) (Α)
上記制御部 131は、室外熱交換器 121の温度および外気温度の両方の温度に基 づいて、ダンバ 113を調整している力 本発明はこれに限定されるものではなぐ室 外熱交換器 121の温度および外気温度のうちのいずれか一方に基づいてダンバ 11 3を調整してもよい。  The control unit 131 adjusts the damper 113 based on both the temperature of the outdoor heat exchanger 121 and the outside air temperature. The present invention is not limited to this, and the outdoor heat exchanger 121 is not limited thereto. The damper 11 3 may be adjusted based on one of the temperature and the outside air temperature.
すなわち、室外熱交換器 121の温度のみに基づいてダンバ 113を調整する場合に は、制御部 131は、室外熱交換器 121の温度 θ 1が室外熱交換器 121の表面に湿 気が奪われる可能性がある所定の第 1温度しきい値 δ 1以下になった場合には、第 2 空気流路 150の空気流れを第 1空気流路 140の空気流れよりも相対的に少なくする ように、ダンバ 113を閉じて室外熱交換器 121を通過した空気 FAが吸着材 104へ向 力う空気流れを遮断するので、吸着効率の低下を抑制することが可能である。この場 合、加湿ユニット 102は、温度検出部 114、 115のうち、室外熱交換器 121の温度 Θ 1を検出する第 1温度検出部 114のみ備えていればよい。 また、外気温度の温度のみに基づいてダンバ 113を調整する場合には、制御部 13 1は、外気温度の温度 Θ 2が室外熱交換器 121の表面に湿気が奪われる可能性が ある所定の第 2温度しきい値 δ 2以下になった場合には、第 2空気流路 150の空気 流れを第 1空気流路 140の空気流れよりも相対的に少なくするように、ダンバ 113を 閉じて室外熱交換器 121を通過した空気 FAが吸着材 104へ向力 空気流れを遮断 するので、吸着効率の低下を抑制することが可能である。この場合、加湿ユニット 10 2は、温度検出部 114、 115のうち、外気温度 Θ 2を検出する第 2温度検出部 115の み備えていればよい。 That is, when adjusting the damper 113 based only on the temperature of the outdoor heat exchanger 121, the controller 131 causes the temperature θ1 of the outdoor heat exchanger 121 to be deprived of moisture on the surface of the outdoor heat exchanger 121. The air flow in the second air flow path 150 is relatively less than the air flow in the first air flow path 140 when the possible first temperature threshold δ 1 or less is reached. Since the air FA that has closed the damper 113 and passed through the outdoor heat exchanger 121 blocks the air flow directed to the adsorbent 104, it is possible to suppress a decrease in adsorption efficiency. In this case, the humidification unit 102 only needs to include the first temperature detection unit 114 that detects the temperature Θ 1 of the outdoor heat exchanger 121 among the temperature detection units 114 and 115. In addition, when adjusting the damper 113 based only on the temperature of the outside air temperature, the control unit 131 determines that the temperature Θ 2 of the outside air temperature may be deprived of moisture on the surface of the outdoor heat exchanger 121. When the second temperature threshold value δ 2 or less, the damper 113 is closed so that the air flow in the second air flow path 150 is relatively less than the air flow in the first air flow path 140. Since the air FA that has passed through the outdoor heat exchanger 121 blocks the directed air flow to the adsorbent 104, it is possible to suppress a decrease in adsorption efficiency. In this case, the humidifying unit 102 only needs to include only the second temperature detection unit 115 that detects the outside air temperature Θ 2 among the temperature detection units 114 and 115.

上記制御部 131は、空気流れ調整部であるダンバ 113を閉じて室外熱交換器 121 を通過した空気 FAが吸着材 104へ向力う空気流れを遮断することにより、第 2空気 流路 150の空気流れを第 1空気流路 140の空気流れよりも相対的に少なくするように 空気流れを調整しているが、本発明はこれに限定されるものではない。変形例として 、第 1空気流路 140の空気流れを増やすことにより、第 2空気流路 150の空気流れを 第 1空気流路 140の空気流れよりも相対的に少なくするようにしてもよい。この場合、 空気流れ調整部は、第 1空気流路 140の空気流れを増やすための手段であればい かなる手段でもよぐ補助ファンなど力もなる。また、空気流れ調整部のさらに他の態 様として、第 1空気流路 140の空気流れを増やすためにケーシング 110の一部を開 閉するための補助ダンバなどでもよ 、。  The control unit 131 closes the damper 113, which is an air flow adjusting unit, and blocks the air flow that the air FA that has passed through the outdoor heat exchanger 121 is directed to the adsorbent 104. Although the air flow is adjusted so that the air flow is relatively less than the air flow of the first air flow path 140, the present invention is not limited to this. As a modification, the air flow in the second air flow path 150 may be relatively less than the air flow in the first air flow path 140 by increasing the air flow in the first air flow path 140. In this case, the air flow adjusting unit can be any means for increasing the air flow in the first air flow path 140 and can also be a force such as an auxiliary fan. Further, as another form of the air flow adjusting unit, an auxiliary damper for opening and closing a part of the casing 110 in order to increase the air flow in the first air flow path 140 may be used.

Moreover, it is necessary for the adsorption fan and the humidification fan to supply air with an air volume and pressure suitable for adsorption and desorption of the adsorbent, respectively. For this reason, fans cannot be shared, and it is difficult to reduce product cost and power consumption.
そこで、第 7実施形態では、ファンを共通化することによって製品コストおよび消費 電力を低減することができる加湿ユニットを提供する。  Therefore, the seventh embodiment provides a humidifying unit that can reduce product cost and power consumption by using a common fan.

第 7実施形態の加湿ユニットは、室外に配置されている。加湿ユニットは、バッチ式 である。加湿ユニットは、ダクトを介して室内に加湿空気を送る。加湿ユニットは、吸着 材と、ファンとを備えている。吸着材は、空気中の水分を吸着する。ファンは、吸着材 の吸着および脱離のための空気を吸着材へ供給する。ファンは、ファンロータと、切 換部材とを有している。切換部材は、第 1状態と、第 2状態とを切り換える。第 1状態 は、ファンロータからの遠心方向への送風を許容する状態である。第 2状態は、遠心 方向への送風を抑える状態である。 The humidifying unit according to the seventh embodiment is arranged outdoors. The humidification unit is a batch type. The humidifying unit sends humid air into the room through the duct. Humidification unit is adsorption Material and a fan. The adsorbent adsorbs moisture in the air. The fan supplies air for adsorption and desorption of the adsorbent to the adsorbent. The fan has a fan rotor and a switching member. The switching member switches between the first state and the second state. The first state is a state in which air blown in the centrifugal direction from the fan rotor is allowed. The second state is a state where air flow in the centrifugal direction is suppressed.
[0061] ここでは、切換部材によってファンロータ力 の遠心方向への送風を許容する第 1 状態と遠心方向への送風を抑える第 2状態とを切り換えることが可能である。これによ り、吸着および脱離にそれぞれ適した圧力および風量の空気流れを 1つのファンによ つて発生させることが可能である。 Here, it is possible to switch between the first state in which the fan rotor force is allowed to blow in the centrifugal direction and the second state in which the blown air in the centrifugal direction is suppressed by the switching member. As a result, it is possible to generate an air flow having a pressure and an air volume suitable for adsorption and desorption with a single fan.
また、第 7実施形態の加湿ユニットは、切換部材は、吸着材の吸着時において、第 1状態に切り換えることにより、ファンが低静圧で大風量の空気を吸着材へ供給する ことを可能にする。かつ、切換部材は、吸着材の脱離時において、第 2状態に切り換 えることにより、ファンが高静圧で小風量の空気を吸着材へ供給することを可能にす る。  In the humidifying unit of the seventh embodiment, the switching member switches to the first state when the adsorbent is adsorbed, so that the fan can supply a large amount of air to the adsorbent with a low static pressure. To do. In addition, the switching member switches to the second state when the adsorbent is detached, thereby enabling the fan to supply a small amount of air to the adsorbent with a high static pressure.
ここでは、吸着時において、切換部材が第 1状態に切り換えることにより、ファンが低 静圧で大風量の空気を吸着材へ供給することが可能である。脱離時において、切換 部材が第 2状態に切り換えることにより、ファンが高静圧で小風量の空気を吸着材へ 供給することが可能である。  Here, at the time of adsorption, the switching member is switched to the first state, so that the fan can supply a large amount of air to the adsorbent with a low static pressure. At the time of detachment, the switching member switches to the second state, so that the fan can supply air with a high static pressure and a small air volume to the adsorbent.
[0062] また、第 7実施形態の加湿ユニットは、切換部材は、遠心方向に対して交差する方 向へ移動することにより、第 1状態と第 2状態とを切り換える。 [0062] In the humidifying unit of the seventh embodiment, the switching member switches between the first state and the second state by moving in a direction crossing the centrifugal direction.
ここでは、切換部材を遠心方向に対して交差する方向へ移動することにより、第 1状 態と第 2状態とを容易かつ確実に切り換えることが可能である。  Here, it is possible to easily and reliably switch between the first state and the second state by moving the switching member in a direction crossing the centrifugal direction.
また、第 7実施形態の加湿ユニットは、ファンケーシングをさらに備えている。ファン ケーシングは、ファンロータを収納する。切換部材は、ファンケーシングと接触する接 合面にシール材を有して 、る。  The humidification unit of the seventh embodiment further includes a fan casing. The fan casing houses the fan rotor. The switching member has a sealing material on the contact surface that contacts the fan casing.
ここでは、切換部材がファンケーシングと接触する接合面にシール材を有して 、る ので、第 2状態において、切換部材がファンロータからの遠心方向への送風を抑える ときに、シール材によって、切換部材とファンケーシングとの接合面からの空気の洩 れを抑えることが可能である。 Here, since the switching member has the sealing material on the joint surface in contact with the fan casing, in the second state, when the switching member suppresses the blowing in the centrifugal direction from the fan rotor, Air leakage from the joint surface between the switching member and the fan casing It is possible to suppress this.
[0063] また、第 7実施形態の加湿ユニットは、切換部材は、ディフューザである。  [0063] In the humidifying unit of the seventh embodiment, the switching member is a diffuser.
ここでは、切換部材がディフューザであるので、第 1状態における遠心方向への空 気流れを所定の風量および圧力に調整することが可能である。  Here, since the switching member is a diffuser, the air flow in the centrifugal direction in the first state can be adjusted to a predetermined air volume and pressure.

As shown in FIG. 32, the adsorbent 304 has a first end 304b located on the downstream side of the air flow, and a second end 304c facing the first end 304b. An air inlet 307 a of the fan 307 is connected to the air flow path 312. The air inlet 307a is disposed in the vicinity of the first end 304b of the adsorbent 304.

Filter 304a is shown in FIG. Further, the adsorbent 304 is a portion that protrudes on both sides of the air flow path 312. Therefore, the filter 304 a is a closed space forming member together with the heater cover 306 and the adsorbent 304. Thereby, the cleanliness of the air introduced into the closed space 311 can be increased.
<ファン 307の構成 >  <Fan 307 configuration>
ファン 307は、図 28〜図 30に示されるように、吸着材 304の吸着および脱離のた めの空気を吸着材 304へ供給する。  The fan 307 supplies air for adsorption and desorption of the adsorbent 304 to the adsorbent 304 as shown in FIGS.
[0067] ファン 307は、ファンロータ 371と、ファンモータ 372と、ファンケーシング 373と、デ ィフューザ 374と、ディフューザ駆動部 375とを備えて 、る。 The fan 307 includes a fan rotor 371, a fan motor 372, a fan casing 373, a diffuser 374, and a diffuser driving unit 375.
ファンロータ 371は、ファンモータ 372の回転軸 372aに固定されている。ファンロー タ 371は、リング状の主板 371aの内周縁部に多数のフィン 371bが立設されたターボ ファン (具体的には、遠心 +斜流の複合ファン)である。  The fan rotor 371 is fixed to the rotating shaft 372a of the fan motor 372. The fan rotor 371 is a turbo fan (specifically, a centrifugal + diagonal flow composite fan) in which a large number of fins 371b are erected on the inner peripheral edge of a ring-shaped main plate 371a.
ファンケーシング 373は、スクロール形状を有するスクロールケーシングであり、下 面側にファン 307の吸気口 307aが形成され、側部にファン 307の排気口 307bが形 成されている。また、ファンケーシング 373の上面側には、ディフューザ 374によって 開閉される開口 307cが形成されている。  The fan casing 373 is a scroll casing having a scroll shape, and an air inlet 307a of the fan 307 is formed on the lower side, and an air outlet 307b of the fan 307 is formed on the side. An opening 307 c that is opened and closed by the diffuser 374 is formed on the upper surface side of the fan casing 373.
ディフューザ 374は、ファンロータ 371からの遠心方向への送風である吸着排気 F3 (図 29〜図 32参照)を許容する第 1状態と、吸着排気 F3を抑える第 2状態とを切り換 える切換部材である。  The diffuser 374 is a switching member that switches between a first state that allows the adsorption exhaust F3 (see FIGS. 29 to 32) that is blown in the centrifugal direction from the fan rotor 371 and a second state that suppresses the adsorption exhaust F3. It is.
[0068] ディフューザ 374によって開閉される開口 307cは、第 1状態における遠心方向へ の空気流れである吸着排気 F3の吹出口となっている。開口 307c近傍のファンケー シング 373内側の空気流路は、ディフューザ 374の内面とファンケーシング 373の内 面によって形成されている。したがって、ディフューザ 374は、第 1状態における遠心 方向への空気流れである吸着排気 F3を所定の風量および圧力に調整することが可 能である。  [0068] The opening 307c opened and closed by the diffuser 374 serves as a blowout port for the adsorbed exhaust F3, which is the air flow in the centrifugal direction in the first state. An air flow path inside the fan casing 373 near the opening 307c is formed by the inner surface of the diffuser 374 and the inner surface of the fan casing 373. Therefore, the diffuser 374 can adjust the adsorption exhaust F3, which is the air flow in the centrifugal direction in the first state, to a predetermined air volume and pressure.
ディフューザ 374は、ファンケーシング 373の上面側の開口 307cを覆うように設け られている。ディフューザ 374は、ディフューザ駆動部 375によって、ファンロータ 37 1の遠心方向（吸着排気 F3の向き）に対して交差する方向、例えば回転軸 372aの延 びる方向 Dlに沿って往復移動することにより、開口 307cを開閉することが可能であ る。これにより、ディフューザ 374は、吸着材 304の吸着時において、上方へ移動して 開口 307cを開放させて第 1状態に切り換える。これにより、ファン 307が低静圧で大 風量の空気を吸着材 304へ供給することを可能にする。一方、吸着材 304の脱離時 において、ディフューザ 374は、下方へ移動して開口 307cを閉じて第 2状態に切り 換えることにより、ファン 307が高静圧で小風量の空気を吸着材 304へ供給すること を可能にする。 The diffuser 374 is provided so as to cover the opening 307c on the upper surface side of the fan casing 373. The diffuser 374 has a direction that intersects the centrifugal direction of the fan rotor 371 (the direction of the adsorption exhaust F3) by the diffuser driving unit 375, for example, the extension of the rotation shaft 372a. The opening 307c can be opened and closed by reciprocating along the sliding direction Dl. Thus, the diffuser 374 moves upward to open the opening 307c and switch to the first state when the adsorbent 304 is adsorbed. This enables the fan 307 to supply a large amount of air to the adsorbent 304 with a low static pressure. On the other hand, when the adsorbent 304 is desorbed, the diffuser 374 moves downward, closes the opening 307c and switches to the second state, so that the fan 307 has a high static pressure and a small air volume to the adsorbent 304. Make it possible to supply.

The drive motor 377 is a stepping motor that rotationally drives the drive gear 378. The drive gear 378 has a round bar shape, and a screw 378a is formed on the surface thereof. The lower end portion of the drive gear 378 is rotatably supported by the central fixing portion 380 of the fan casing 373. The upper end of the drive gear 378 is connected to the drive shaft 377a of the drive motor 377. The gear receiving portion 379 has a cylindrical shape, and an internal thread is formed on the inner surface of the gear receiving portion 379 so as to be screwed with the male screw 378a of the driving gear 378. The gear receiving portion 379 is formed integrally with the diffuser 374.
ディフューザ駆動部 375では、駆動用モータ 377が駆動用ギア 378を正転または 逆転させることにより、駆動用ギア 378に螺合しているギア受け部 379、およびギア受 け部 379と一体になつているディフューザ 374を回転軸 372aの延びる方向 D1に沿 つて往復移動させることが可能である。これによつて、ディフューザ 374は、上記の第 1状態と第 2状態とを切り換えることが可能である。  In the diffuser drive unit 375, the drive motor 377 rotates the drive gear 378 forward or reverse so that the gear receiver 379 is screwed with the drive gear 378, and the gear receiver 379 is integrated with the gear receiver 379. The diffuser 374 can be reciprocated along the direction D1 in which the rotating shaft 372a extends. Thereby, the diffuser 374 can switch between the first state and the second state.
[0070] また、ディフューザ 374の周縁部には、ディフューザ 374を閉めたときにディフュー ザ 374とファンケーシング 373との隙間力も空気が洩れないように、発泡ゴムなどから なるシール材 376が設けられている。 [0070] In addition, a sealing material 376 made of foamed rubber or the like is provided at the peripheral portion of the diffuser 374 so that air does not leak even when the diffuser 374 is closed when the diffuser 374 is closed.

図 32および図 33に示されるように、ケーシング 310の内部に導入される空気である 吸気 F1は、まず、吸着材 304の両端部であるフィルタ 304aから閉空間 311の内部 に下方カゝら導入される。  As shown in FIG. 32 and FIG. 33, the intake air F1, which is the air introduced into the casing 310, is first introduced into the closed space 311 from the filter 304a that is both ends of the adsorbent 304. Is done.
ついで、閉空間 311に導入された空気は、通気性を有する吸着材 304を通過して 空気流路 312に進む（吸着材通過空気 F2参照)。  Next, the air introduced into the closed space 311 passes through the adsorbent 304 having air permeability and proceeds to the air flow path 312 (see adsorbent passing air F2).
そののち、吸着材通過空気 F2は、空気流路 312を通って吸着材 304の下流側の 第 1の端部 304bに配置されたファン 307の吸気口 307aを通してファン 307の内部 に導入される。  After that, the adsorbent passing air F2 is introduced into the fan 307 through the air flow path 312 and through the air inlet 307a of the fan 307 disposed at the first end 304b on the downstream side of the adsorbent 304.
そののち、吸着動作の場合には、ディフューザ 374およびルーパダンパ 309が開い ているので、吸着排気 F3として開口 307cから遠心方向に外部へ吹き出すとともに残 存排気 F33が排気口 307bから室外へ吹き出す。  After that, in the case of the adsorption operation, since the diffuser 374 and the looper damper 309 are opened, the adsorption exhaust F3 is blown out from the opening 307c in the centrifugal direction, and the residual exhaust F33 is blown out from the exhaust port 307b to the outside.
また、加湿動作の場合には、ディフューザ 374およびルーパダンパ 309が閉じてい るので、加湿空気 F4として排気口 307bからダクト 308を介して室内へ送られる。 第 7実施形態の加湿ユニット 302は、ノ ツチ式の加湿ユニット、およびそれを用いた 空気調和機の室外機に利用することが可能である。 In the humidifying operation, since the diffuser 374 and the looper damper 309 are closed, the humidified air F4 is sent from the exhaust port 307b to the room through the duct 308. The humidifying unit 302 of the seventh embodiment can be used for a notch type humidifying unit and an outdoor unit of an air conditioner using the humidifying unit.
<第 7実施形態の特徴 > <Features of the seventh embodiment>
(1) (1)
第 7実施形態の加湿ユニット 302では、切換部材であるディフューザ 374によって、 ファンロータ 371からの遠心方向への送風である吸着排気 F3を許容する第 1状態と 吸着排気 F3を抑える第 2状態とを切り換えることが可能である。これにより、吸着およ び脱離にそれぞれ適した圧力および風量の空気流れを 1つのファン 307によって発 生させることが可能である。その結果、吸着用ファンおよび脱離用ファンを共通化す ることができ、製品コストおよび消費電力を低減することが可能である。  In the humidifying unit 302 of the seventh embodiment, the diffuser 374 as a switching member has a first state in which the adsorbed exhaust F3 that is blown in the centrifugal direction from the fan rotor 371 and a second state in which the adsorbed exhaust F3 is suppressed. It is possible to switch. Thus, it is possible to generate an air flow having a pressure and an air volume suitable for adsorption and desorption, respectively, by one fan 307. As a result, the suction fan and the desorption fan can be used in common, and the product cost and power consumption can be reduced.
(2) (2)
第 7実施形態の加湿ユニット 302では、吸着時において、ディフューザ 374が第 1 状態に切り換えることにより、ファン 307が低静圧で大風量の空気を吸着材 304へ供 給することが可能である。脱離時において、ディフューザ 374が第 2状態に切り換える ことにより、ファン 307が高静圧で小風量の空気を吸着材 304へ供給することが可能 である。  In the humidifying unit 302 of the seventh embodiment, the diffuser 374 switches to the first state during adsorption, so that the fan 307 can supply a large amount of air to the adsorbent 304 with a low static pressure. At the time of desorption, the diffuser 374 is switched to the second state, so that the fan 307 can supply a small amount of air to the adsorbent 304 with a high static pressure.
(3) (3)
第 7実施形態の加湿ユニット 302では、ディフューザ 374を遠心方向（吸着排気 F3 の向き）に対して交差する方向である、回転軸 372aの延びる方向 D1へ移動すること により、第 1状態と第 2状態とを容易かつ確実に切り換えることが可能である。  In the humidifying unit 302 of the seventh embodiment, the first state and the second state are obtained by moving the diffuser 374 in a direction D1 in which the rotation shaft 372a extends, which is a direction intersecting the centrifugal direction (the direction of the adsorption exhaust F3). It is possible to easily and reliably switch the state.
(4) (Four)
第 7実施形態の加湿ユニット 302では、ディフューザ 374がファンケーシング 373と 接触する接合面にシール材 376を有しているので、第 2状態において、ディフューザ 374がファンロータ 371からの遠心方向への送風である吸着排気 F3を抑えるときに、 シール材 376によって、ディフューザ 374とファンケーシングとの接合面からの空気 の洩れを抑えることが可能である。  In the humidifying unit 302 of the seventh embodiment, since the diffuser 374 has the sealing material 376 on the joint surface in contact with the fan casing 373, in the second state, the diffuser 374 blows air from the fan rotor 371 in the centrifugal direction. When suppressing the adsorbed exhaust F3, the sealing material 376 can suppress air leakage from the joint surface between the diffuser 374 and the fan casing.
(5) (Five)
第 7実施形態の加湿ユニット 302では、切換部材としてディフューザ 374が採用さ れているので、第 1状態における遠心方向への空気流れである吸着排気 F3を所定 の風量および圧力に調整することが可能である。 In the humidifying unit 302 of the seventh embodiment, a diffuser 374 is employed as a switching member. Therefore, the adsorption exhaust F3, which is the air flow in the centrifugal direction in the first state, can be adjusted to a predetermined air volume and pressure.
<第 7実施形態の変形例 > <Modification of the seventh embodiment>
(A) (A)
第 7実施形態では、ディフューザ 374を回転軸 372aの延びる方向 D1へ移動する 態様を例にあげて説明した力 本発明はこれに限定されるものではなぐディフュー ザ 374を遠心方向（吸着排気 F3の向き）に対して交差する方向へ移動するのであれ ば、いずれの交差方向においても第 1状態と第 2状態とを容易かつ確実に切り換える ことが可能である。  In the seventh embodiment, the force described by taking as an example the mode of moving the diffuser 374 in the extending direction D1 of the rotating shaft 372a. The present invention is not limited to this. The diffuser 374 is moved in the centrifugal direction (of the adsorbed exhaust F3). It is possible to easily and reliably switch between the first state and the second state in any crossing direction as long as it moves in the direction crossing the direction.
