That is, the switching mechanism (200) has the heat exchange chamber (S11, S12) provided with the adsorption heat exchanger (101, 102) serving as an evaporator among the first and second heat exchange chambers (S11, S12). Passed air is supplied to the humidity control space (S0), and air for regenerating the adsorbent flows in the heat exchange chamber (S12, S11) where the adsorption heat exchanger (102, 101), which is a condenser, is installed. The air flow is switched.
　　　《吸着熱交換器を通過する空気の流通方向》
　なお、この例では、第１および第２熱交換室（S11,S12）の接続状態が第１通路状態である場合（すなわち、第１熱交換室（S11）が給気通路（P1）の一部として組み込まれている場合）に第１吸着熱交換器（101）を通過する空気の流通方向は、第１および第２熱交換室（S11,S12）の接続状態が第２通路状態である場合（すなわち、第１熱交換室（S11）が再生通路（P2）の一部として組み込まれている場合）に第１吸着熱交換器（101）を通過する空気の流通方向と同じ方向となっている（所謂、並行流となっている）。第２吸着熱交換器（102）を通過する空気の流通方向についても同様である。このように、第１および第２吸着熱交換器（101,102）の各々を通過する空気の流通方向は、吸着熱交換器が蒸発器から凝縮器に（または、凝縮器から蒸発器に）切り換わっても変化しない。すなわち、切換機構（200）は、第１および第２吸着熱交換器（101,102）の各々を通過する空気の流通方向が、その吸着熱交換器（101,102）が蒸発器となっている場合とその吸着熱交換器（101,102）が凝縮器となっている場合とで同方向となるように、空気の流れを切り換える。 《Flow direction of air passing through adsorption heat exchanger》
In this example, when the connection state of the first and second heat exchange chambers (S11, S12) is the first passage state (that is, the first heat exchange chamber (S11) is a part of the air supply passage (P1). In the flow direction of the air passing through the first adsorption heat exchanger (101) in the case of being incorporated as a part), the connection state of the first and second heat exchange chambers (S11, S12) is the second passage state. In this case (that is, when the first heat exchange chamber (S11) is incorporated as part of the regeneration passage (P2)), the flow direction is the same as the flow direction of the air passing through the first adsorption heat exchanger (101). (So-called parallel flow). The same applies to the flow direction of the air passing through the second adsorption heat exchanger (102). Thus, the flow direction of the air passing through each of the first and second adsorption heat exchangers (101, 102) is switched from the evaporator to the condenser (or from the condenser to the evaporator). It doesn't change. That is, the switching mechanism (200) has a case where the flow direction of the air passing through each of the first and second adsorption heat exchangers (101, 102) is the same as when the adsorption heat exchanger (101, 102) is an evaporator. The air flow is switched so that the adsorption heat exchanger (101, 102) is in the same direction as the condenser.
　　〈吸着ブロック〉
　第１および第２吸着ブロック（301,302）の各々は、吸着剤が担持されて空気を吸着剤と接触させるように構成されている。例えば、第１および第２吸着ブロック（301,302）の各々は、構造体（具体的には、ハニカム構造を有する構造体）の表面に吸着剤を担持させることによって構成されている。また、第１および第２吸着ブロック（301,302）は、第１および第２熱交換室（S11,S12）にそれぞれ設けられる。なお、以下の説明では、第１および第２吸着ブロック（301,302）の総称を単に「吸着ブロック（301,302）」と表記する。 <Suction block>
Each of the first and second adsorption blocks (301, 302) is configured to carry an adsorbent and bring air into contact with the adsorbent. For example, each of the first and second adsorption blocks (301, 302) is configured by supporting an adsorbent on the surface of a structure (specifically, a structure having a honeycomb structure). The first and second adsorption blocks (301, 302) are provided in the first and second heat exchange chambers (S11, S12), respectively. In the following description, the generic name of the first and second adsorption blocks (301, 302) is simply referred to as “adsorption block (301, 302)”.
　第１吸着ブロック（301）は、第１熱交換室（S11）において、第１吸着熱交換器（101）が蒸発器となっている場合に第１吸着熱交換器（101）の下流側（風下側）となる位置（すなわち、第１熱交換室（S11）が給気通路（P1）の一部として組み込まれている場合に第１吸着熱交換器（101）によって除湿された空気が通過する位置）に配置されている。換言すると、第１吸着ブロック（301）は、第１熱交換室（S11）において、第１および第２熱交換室（S11,S12）の接続状態が第１通路状態（図１の実線で示した状態）である場合に第１吸着熱交換器（101）の下流側となる位置に配置されている。 The first adsorption block (301) is located downstream of the first adsorption heat exchanger (101) when the first adsorption heat exchanger (101) is an evaporator in the first heat exchange chamber (S11) ( Air dehumidified by the first adsorption heat exchanger (101) passes when the position becomes the leeward side (that is, when the first heat exchange chamber (S11) is incorporated as a part of the air supply passage (P1)) Position). In other words, in the first adsorption block (301), in the first heat exchange chamber (S11), the connection state of the first and second heat exchange chambers (S11, S12) is the first passage state (shown by the solid line in FIG. 1). In this case, it is disposed at a position downstream of the first adsorption heat exchanger (101).
　これと同様に、第２吸着ブロック（302）は、第２熱交換室（S12）において、第２吸着熱交換器（102）が蒸発器となっている場合に第２吸着熱交換器（102）の下流側（風下側）となる位置（すなわち、第２熱交換室（S12）が給気通路（P1）の一部として組み込まれている場合に第２吸着熱交換器（102）によって除湿された空気が通過する位置）に配置されている。換言すると、第２吸着ブロック（302）は、第２熱交換室（S12）において、第１および第２熱交換室（S11,S12）の接続状態が第２通路状態（図１の破線で示した状態）である場合に第２吸着熱交換器（102）の下流側となる位置に配置されている。 Similarly, when the second adsorption heat exchanger (102) is an evaporator in the second heat exchange chamber (S12), the second adsorption block (302) has the second adsorption heat exchanger (102). ) On the downstream side (leeward side) (that is, when the second heat exchange chamber (S12) is incorporated as a part of the air supply passage (P1), the second adsorption heat exchanger (102) removes the moisture. At a position where the generated air passes). In other words, in the second adsorption block (302), in the second heat exchange chamber (S12), the connection state of the first and second heat exchange chambers (S11, S12) is the second passage state (indicated by the broken line in FIG. 1). The second adsorption heat exchanger (102) is disposed at a position downstream of the second adsorption heat exchanger (102).
　なお、この例では、第１および第２吸着熱交換器（101,102）の各々を通過する空気の流通方向は、その吸着熱交換器（101,102）が蒸発器となっている場合とその吸着熱交換器（101,102）が凝縮器となっている場合とで同方向となっている。したがって、第１および第２熱交換室（S11,S12）の接続状態が第１通路状態（図１の実線で示した状態）である場合に第１吸着熱交換器（101）の下流側となる位置は、第１および第２熱交換室（S11,S12）の接続状態が第２通路状態（図１の破線で示した状態）である場合に第１吸着熱交換器（101）の下流側となる位置と同じ位置である。これと同様に、第１および第２熱交換室（S11,S12）の接続状態が第２通路状態（図１の破線で示した状態）である場合に第２吸着熱交換器（102）の下流側となる位置は、第１および第２熱交換室（S11,S12）の接続状態が第１通路状態（図１の実線で示した状態）である場合に第２吸着熱交換器（102）の下流側となる位置と同じ位置である。すなわち、第１および第２熱交換室（S11,S12）の各々では、吸着ブロック（301,302）は，吸着熱交換器（101,102）が蒸発器となっている場合および吸着熱交換器（101,102）が凝縮器となっている場合のどちらの場合にも、吸着熱交換器（101,102）の下流側に位置する。 In this example, the flow direction of the air passing through each of the first and second adsorption heat exchangers (101, 102) depends on whether the adsorption heat exchanger (101, 102) is an evaporator or the adsorption heat exchange. The direction is the same as when the condenser (101, 102) is a condenser. Therefore, when the connection state of the first and second heat exchange chambers (S11, S12) is the first passage state (the state indicated by the solid line in FIG. 1), the downstream side of the first adsorption heat exchanger (101) Is located downstream of the first adsorption heat exchanger (101) when the connection state of the first and second heat exchange chambers (S11, S12) is the second passage state (shown by the broken line in FIG. 1). It is the same position as the side position. Similarly, when the connection state of the first and second heat exchange chambers (S11, S12) is the second passage state (the state indicated by the broken line in FIG. 1), the second adsorption heat exchanger (102) The position on the downstream side is the second adsorption heat exchanger (102 when the connection state of the first and second heat exchange chambers (S11, S12) is the first passage state (the state shown by the solid line in FIG. 1). It is the same position as the downstream position. That is, in each of the first and second heat exchange chambers (S11, S12), the adsorption block (301, 302) includes an adsorption heat exchanger (101, 102) as an evaporator and an adsorption heat exchanger (101, 102). In either case of a condenser, it is located downstream of the adsorption heat exchanger (101, 102).
　　〈コントローラ〉
　コントローラ（20）は、各種センサ（例えば、温度センサや湿度センサなど）の検出値に基づいて、除湿装置（10）を制御する。例えば、コントローラ（20）は、ＣＰＵやメモリによって構成されている。 <controller>
The controller (20) controls the dehumidifier (10) based on detection values of various sensors (for example, a temperature sensor, a humidity sensor, etc.). For example, the controller (20) is constituted by a CPU and a memory.
　　〈除湿装置による除湿運転〉
　次に、図１を参照して、実施形態１の除湿装置（10）の除湿運転について説明する。この除湿装置（10）は、第１および第２除湿動作を所定の時間間隔（例えば、１０分間隔）で交互に繰り返す。 <Dehumidifying operation with dehumidifier>
Next, the dehumidifying operation of the dehumidifying device (10) of Embodiment 1 will be described with reference to FIG. The dehumidifier (10) repeats the first and second dehumidifying operations alternately at a predetermined time interval (for example, every 10 minutes).
　　　《第１除湿動作》
　第１除湿動作では、圧縮機（103）が駆動され、膨張弁（104）の開度が調節され、四方切換弁（105）が第１接続状態（図１の実線で示した状態）となる。これにより、冷媒回路（100）は、第１吸着熱交換器（101）が蒸発器となり第２吸着熱交換器（102）が凝縮器となる第１冷凍サイクル動作を行う。また、切換機構（200）は、第１および第２熱交換室（S11,S12）の接続状態を第１通路状態（図１の実線で示した状態）に設定する。 << First dehumidifying operation >>
In the first dehumidifying operation, the compressor (103) is driven, the opening degree of the expansion valve (104) is adjusted, and the four-way switching valve (105) is in the first connection state (the state shown by the solid line in FIG. 1). . Thus, the refrigerant circuit (100) performs a first refrigeration cycle operation in which the first adsorption heat exchanger (101) serves as an evaporator and the second adsorption heat exchanger (102) serves as a condenser. Further, the switching mechanism (200) sets the connection state of the first and second heat exchange chambers (S11, S12) to the first passage state (the state indicated by the solid line in FIG. 1).
　　　　－給気通路における空気の流れ－
　給気通路（P1）に取り込まれた空気（この例では、室外空気（OA））は、冷却器（11）によって冷却除湿された後に、第１熱交換室（S11）に供給される。第１熱交換室（S11）に供給された空気は、蒸発器として機能している第１吸着熱交換器（101）を通過する。このとき、第１吸着熱交換器（101）を通過する空気の中の水分が第１吸着熱交換器（101）の吸着剤に吸着する。また、その吸着の際に生じた吸着熱が第１吸着熱交換器（101）を流れる冷媒に吸熱される。このように、蒸発器として機能している第１吸着熱交換器（101）を通過する空気は、第１吸着熱交換器（101）の吸着剤に水分を奪われて湿度が低下するとともに、第１吸着熱交換器（101）を流れる冷媒の吸熱作用により冷却されて温度も低下する。次に、第１吸着熱交換器（101）によって除湿および冷却された空気は、第１吸着ブロック（301）を通過する。このとき、この空気中の水分が第１吸着ブロック（301）の吸着剤に吸着する。これにより、第１吸着熱交換器（101）によって除湿された空気は、第１吸着ブロック（301）によってさらに除湿される。第１吸着熱交換器（101）および第１吸着ブロック（301）を通過して除湿された空気は、供給空気（SA）として室内空間（S1）に供給される。 -Air flow in the air supply passage-
The air taken into the supply passage (P1) (in this example, outdoor air (OA)) is cooled and dehumidified by the cooler (11), and then supplied to the first heat exchange chamber (S11). The air supplied to the first heat exchange chamber (S11) passes through the first adsorption heat exchanger (101) functioning as an evaporator. At this time, moisture in the air passing through the first adsorption heat exchanger (101) is adsorbed by the adsorbent of the first adsorption heat exchanger (101). Further, the heat of adsorption generated during the adsorption is absorbed by the refrigerant flowing through the first adsorption heat exchanger (101). Thus, while the air passing through the first adsorption heat exchanger (101) functioning as an evaporator is deprived of moisture by the adsorbent of the first adsorption heat exchanger (101), the humidity decreases, It is cooled by the endothermic action of the refrigerant flowing through the first adsorption heat exchanger (101), and the temperature also decreases. Next, the air dehumidified and cooled by the first adsorption heat exchanger (101) passes through the first adsorption block (301). At this time, moisture in the air is adsorbed on the adsorbent of the first adsorption block (301). Thereby, the air dehumidified by the first adsorption heat exchanger (101) is further dehumidified by the first adsorption block (301). The air dehumidified after passing through the first adsorption heat exchanger (101) and the first adsorption block (301) is supplied to the indoor space (S1) as supply air (SA).
　　　　－再生通路における空気の流れ－
　再生通路（P2）に取り込まれた空気（この例では、室内空気（RA））は、第２熱交換室（S12）に供給される。第２熱交換室（S12）に供給された空気は、凝縮器として機能している第２吸着熱交換器（102）を通過する。このとき、第２吸着熱交換器（102）を通過する空気が第２吸着熱交換器（102）を流れる冷媒によって加熱される。また、第２吸着熱交換器（102）の吸着剤中の水分が第２吸着熱交換器（102）を通過する空気の中に放出される。これにより、第２吸着熱交換器（102）の吸着剤が再生される。このように、凝縮器として機能している第２吸着熱交換器（102）を通過する空気は、第２吸着熱交換器（102）の吸着剤から水分を付与されて湿度が上昇するとともに、第２吸着熱交換器（102）を流れる冷媒の放熱作用により加熱されて温度も上昇する。次に、第２吸着熱交換器（102）によって加湿および加熱された空気は、第２吸着ブロック（302）を通過する。このとき、第２吸着ブロック（302）の吸着剤の水分が第２吸着ブロック（302）を通過する空気に放出される。これにより、第２吸着ブロック（302）の吸着剤が再生される。第２吸着熱交換器（102）および第２吸着ブロック（302）を通過した空気は、排出空気（EA）として室外空間に排出される。 -Air flow in the regeneration passage-
Air (in this example, room air (RA)) taken into the regeneration passage (P2) is supplied to the second heat exchange chamber (S12). The air supplied to the second heat exchange chamber (S12) passes through the second adsorption heat exchanger (102) functioning as a condenser. At this time, the air passing through the second adsorption heat exchanger (102) is heated by the refrigerant flowing through the second adsorption heat exchanger (102). In addition, moisture in the adsorbent of the second adsorption heat exchanger (102) is released into the air passing through the second adsorption heat exchanger (102). Thereby, the adsorbent of the second adsorption heat exchanger (102) is regenerated. Thus, while the air passing through the second adsorption heat exchanger (102) functioning as a condenser is given moisture from the adsorbent of the second adsorption heat exchanger (102), the humidity rises, It is heated by the heat radiation action of the refrigerant flowing through the second adsorption heat exchanger (102), and the temperature also rises. Next, the air humidified and heated by the second adsorption heat exchanger (102) passes through the second adsorption block (302). At this time, the moisture of the adsorbent of the second adsorption block (302) is released to the air passing through the second adsorption block (302). Thereby, the adsorbent of the second adsorption block (302) is regenerated. The air that has passed through the second adsorption heat exchanger (102) and the second adsorption block (302) is exhausted to the outdoor space as exhaust air (EA).
　　　《第２除湿動作》
　第２除湿動作では、圧縮機（103）が駆動され、膨張弁（104）の開度が調節され、四方切換弁（105）が第２接続状態（図１の破線で示した状態）となる。これにより、冷媒回路（100）は、第１吸着熱交換器（101）が凝縮器となり第２吸着熱交換器（102）が蒸発器となる第２冷凍サイクル動作を行う。また、切換機構（200）は、第１および第２熱交換室（S11,S12）の接続状態を第２通路状態（図１の破線で示した状態）に設定する。 <Second dehumidifying operation>
In the second dehumidifying operation, the compressor (103) is driven, the opening degree of the expansion valve (104) is adjusted, and the four-way switching valve (105) is in the second connection state (the state indicated by the broken line in FIG. 1). . Thereby, the refrigerant circuit (100) performs a second refrigeration cycle operation in which the first adsorption heat exchanger (101) serves as a condenser and the second adsorption heat exchanger (102) serves as an evaporator. Further, the switching mechanism (200) sets the connection state of the first and second heat exchange chambers (S11, S12) to the second passage state (the state indicated by the broken line in FIG. 1).

Thereby, the adsorbent of the first adsorption heat exchanger (101) is regenerated. Next, the air humidified and heated by the first adsorption heat exchanger (101) passes through the first adsorption block (301). At this time, the moisture of the adsorbent of the first adsorption block (301) is released to the air passing through the first adsorption block (301).

　以上のように、第１および第２熱交換室（S11,S12）における空気の除湿量を増加させることができ、さらに、吸着ブロック（301,302）の吸着剤への水分の吸着を促進させることができるので、除湿装置（10）の除湿能力を向上させることができる。 As described above, the amount of air dehumidified in the first and second heat exchange chambers (S11, S12) can be increased, and further, the adsorption of moisture to the adsorbent of the adsorption block (301, 302) can be promoted. Therefore, the dehumidifying capacity of the dehumidifying device (10) can be improved.
　また、除湿装置（10）の除湿能力を向上させるために冷媒回路（100）の圧縮機（103）の回転数を増加させなくてもよいので、除湿装置（10）の消費電力の増大を抑制することができる。 Moreover, since it is not necessary to increase the rotation speed of the compressor (103) of the refrigerant circuit (100) in order to improve the dehumidifying capacity of the dehumidifying device (10), the increase in power consumption of the dehumidifying device (10) is suppressed. can do.

When installed, air heated by the second adsorption heat exchanger (102) can be supplied to the second adsorption block (302). Thereby, regeneration of the adsorbent of the second adsorption block (302) can be promoted. Thus, since regeneration of the adsorbent of the adsorption block (301, 302) can be promoted, the dehumidifying ability of the dehumidifying device (10) can be further improved.
　また、第１吸着熱交換器（101）と間隔をおいて第１吸着ブロック（301）を配置することにより、第１吸着ブロック（301）における温度分布の偏りや空気偏流を抑制することができる。第２吸着ブロック（302）についても同様である。このように、第１および第２吸着ブロック（301,302）において温度分布の偏りや空気偏流を抑制することができるので、第１および第２吸着ブロック（301,302）における吸着能力および再生能力の低下を抑制することができる。 Further, by disposing the first adsorption block (301) at a distance from the first adsorption heat exchanger (101), it is possible to suppress temperature distribution deviation and air drift in the first adsorption block (301). . The same applies to the second adsorption block (302). As described above, since the temperature distribution and air drift can be suppressed in the first and second adsorption blocks (301, 302), the decrease in adsorption capacity and regeneration capacity in the first and second adsorption blocks (301, 302) is suppressed. can do.

When the air supplied to the second heat exchange chamber (S12) sequentially passes through the second adsorption heat exchanger (102) and the second adsorption block (302), the second adsorption heat exchanger (102) and Water is applied from the adsorbent of the second adsorption block (302). Thereby, the adsorbent of the second adsorption heat exchanger (102) and the second adsorption block (302) is regenerated. The air that has passed through the second heat exchange chamber (S12) is exhausted to the outdoor space as exhaust air (EA).

　第４除湿動作では、圧縮機（103）が駆動され、膨張弁（104）の開度が調節され、四方切換弁（105）が第２接続状態（図６の破線で示した状態）となる。これにより、冷媒回路（100）は、第１吸着熱交換器（101）が凝縮器となり第２吸着熱交換器（102）が蒸発器となる第２冷凍サイクル動作を行う。また、切換機構（200）は、第１および第２熱交換室（S11,S12）の接続状態を第４通路状態（図６の破線で示した状態）に設定する。 << 4th dehumidifying action >>
In the fourth dehumidifying operation, the compressor (103) is driven, the opening degree of the expansion valve (104) is adjusted, and the four-way switching valve (105) is in the second connection state (the state indicated by the broken line in FIG. 6). . Thereby, the refrigerant circuit (100) performs a second refrigeration cycle operation in which the first adsorption heat exchanger (101) serves as a condenser and the second adsorption heat exchanger (102) serves as an evaporator. Further, the switching mechanism (200) sets the connection state of the first and second heat exchange chambers (S11, S12) to the fourth passage state (the state indicated by the broken line in FIG. 6).
　前処理通路（P3）に取り込まれた空気（この例では、室外空気（OA））は、冷却器（11）によって冷却除湿された後に、第２熱交換室（S12）に供給される。第２熱交換室（S12）に供給された空気は、第２吸着熱交換器（102）と第２吸着ブロック（302）とを順に通過する際に、第２吸着熱交換器（102）および第２吸着ブロック（302）の吸着剤に水分を奪われて除湿される。第２熱交換室（S12）において除湿された空気は、供給空気（SA0）として室内空間（S1）に供給される。 The air taken into the pretreatment passage (P3) (in this example, outdoor air (OA)) is cooled and dehumidified by the cooler (11) and then supplied to the second heat exchange chamber (S12). When the air supplied to the second heat exchange chamber (S12) sequentially passes through the second adsorption heat exchanger (102) and the second adsorption block (302), the second adsorption heat exchanger (102) and Moisture is taken away by the adsorbent of the second adsorption block (302) and dehumidified. The air dehumidified in the second heat exchange chamber (S12) is supplied to the indoor space (S1) as supply air (SA0).
　後処理通路（P4）に取り込まれた空気（この例では、再生通路（P2）から供給された空気）は、第１熱交換室（S11）に供給される。第１熱交換室（S11）に供給された空気は、第１吸着熱交換器（101）と第１吸着ブロック（301）とを順に通過する際に、第１吸着熱交換器（101）および第１吸着ブロック（301）の吸着剤から水分を付与される。これにより、第１吸着熱交換器（101）および第１吸着ブロック（301）の吸着剤が再生される。第１熱交換室（S11）を通過した空気は、排出空気（EA）として室外空間に排出される。 The air taken into the post-processing passage (P4) (in this example, air supplied from the regeneration passage (P2)) is supplied to the first heat exchange chamber (S11). When the air supplied to the first heat exchange chamber (S11) passes through the first adsorption heat exchanger (101) and the first adsorption block (301) in order, the first adsorption heat exchanger (101) and Water is applied from the adsorbent of the first adsorption block (301). Thereby, the adsorbent of the first adsorption heat exchanger (101) and the first adsorption block (301) is regenerated. The air that has passed through the first heat exchange chamber (S11) is exhausted to the outdoor space as exhaust air (EA).
　　〈実施形態１の変形例３による効果〉
　以上のように、室内空間（S1）に供給するための空気（この例では、室外空気（OA））を前処理用除湿装置（30）によって除湿して供給空気（SA0）として室内空間（S1）に供給し、室内空間（S1）から供給された室内空気（RA）を除湿装置（10）によって除湿して供給空気（SA）としてチャンバ（S2）に供給することにより、チャンバ（S2）内の空気の露点温度を室内空間（S1）内の空気の露点温度よりも低くすることができる。このように、チャンバ（S2）に低露点の供給空気（SA）を集中的に供給することにより、室内空間（S1）全体を低露点にする場合よりも、除湿システム（1）の運転動作に要する消費電力を低減することができる。 <Effects of Modification 3 of Embodiment 1>
As described above, the air to be supplied to the indoor space (S1) (in this example, the outdoor air (OA)) is dehumidified by the pretreatment dehumidifier (30) and supplied to the indoor space (S1). In the chamber (S2), the indoor air (RA) supplied from the indoor space (S1) is dehumidified by the dehumidifier (10) and supplied to the chamber (S2) as the supply air (SA). The dew point temperature of the air can be made lower than the dew point temperature of the air in the indoor space (S1). In this way, by supplying supply air (SA) with a low dew point to the chamber (S2) in a concentrated manner, the dehumidification system (1) can be operated more than when the entire indoor space (S1) is set to a low dew point. The power consumption required can be reduced.
　（実施形態２）
　図７は、実施形態２による除湿システム（1）の構成例を示している。この除湿システム（1）は、除湿装置（10）とコントローラ（20）と加熱器（21）とを備えている。なお、実施形態２の除湿装置（10）の構造は、実施形態１の除湿装置（10）の構造（図２）と異なっている。具体的には、第１および第２吸着熱交換器（101,102）を通過する空気の流通方向と、第１および第２吸着ブロック（301,302）の配置が、実施形態１と異なっている。その他の構成は、実施形態１と同様である。 (Embodiment 2)
FIG. 7 shows a configuration example of the dehumidification system (1) according to the second embodiment. The dehumidifying system (1) includes a dehumidifying device (10), a controller (20), and a heater (21). In addition, the structure of the dehumidification apparatus (10) of Embodiment 2 differs from the structure (FIG. 2) of the dehumidification apparatus (10) of Embodiment 1. FIG. Specifically, the flow direction of the air passing through the first and second adsorption heat exchangers (101, 102) and the arrangement of the first and second adsorption blocks (301, 302) are different from those in the first embodiment. Other configurations are the same as those of the first embodiment.
　　〈加熱器〉
　加熱器（21）は、再生通路（P2）に設けられ、第１および第２熱交換室（S11,S12）のうち凝縮器となっている吸着熱交換器が設けられた熱交換室の上流側（風上側）に配置されている。すなわち、加熱器（21）は、吸着剤を再生するための空気を加熱するように構成されている。この例では、加熱器（21）は、第１再生通路部（P21）に配置されている。例えば、加熱器（21）は、第１再生通路部（P21）を流れる空気と第２再生通路部（P22）を流れる空気との間で熱交換を行う顕熱熱交換器によって構成されていてもよいし、冷媒回路（図示を省略）の凝縮器として機能する熱交換器（具体的には、フィンアンドチューブ式の熱交換器）などによって構成されていてもよい。 <Heater>
The heater (21) is provided in the regeneration passage (P2) and is upstream of the heat exchange chamber in which the adsorption heat exchanger serving as a condenser is provided among the first and second heat exchange chambers (S11, S12). It is arranged on the side (windward side). That is, the heater (21) is configured to heat air for regenerating the adsorbent. In this example, the heater (21) is disposed in the first regeneration passage portion (P21). For example, the heater (21) is constituted by a sensible heat exchanger that exchanges heat between the air flowing through the first regeneration passage (P21) and the air flowing through the second regeneration passage (P22). Alternatively, a heat exchanger (specifically, a fin-and-tube heat exchanger) that functions as a condenser of a refrigerant circuit (not shown) may be used.
　　〈冷媒回路〉
　冷媒回路（100）は、実施形態１と同様に、コントローラ（20）による制御に応答して、第１吸着熱交換器（101）が蒸発器となって空気を除湿し第２吸着熱交換器（102）が凝縮器となって吸着剤を再生させる第１冷凍サイクル動作と、第２吸着熱交換器（102）が蒸発器となって空気を除湿し第１吸着熱交換器（101）が凝縮器となって吸着剤を再生させる第２冷凍サイクル動作とを交互に行うように構成されている。 <Refrigerant circuit>
As in the first embodiment, the refrigerant circuit (100) responds to the control by the controller (20), and the first adsorption heat exchanger (101) serves as an evaporator to dehumidify the air and the second adsorption heat exchanger. The first refrigeration cycle operation in which (102) serves as a condenser to regenerate the adsorbent, and the second adsorption heat exchanger (102) serves as an evaporator to dehumidify the air and the first adsorption heat exchanger (101) The second refrigeration cycle operation for regenerating the adsorbent as a condenser is performed alternately.
　　〈切換機構〉
　切換機構（200）は、コントローラ（20）による制御に応答して、第１および第２熱交換室（S11,S12）の接続状態を、第１通路状態（図７の実線で示した状態）と第２通路状態（図７の破線で示した状態）とに設定可能に構成されている。また、切換機構（200）は、四方切換弁（105）が第１接続状態（図７の実線で示した状態）である場合に、第１および第２熱交換室（S11,S12）の接続状態を第１通路状態に設定し、四方切換弁（105）が第２接続状態である場合（図７の破線で示した状態）に、第１および第２熱交換室（S11,S12）の接続状態を第２通路状態に設定する。すなわち、切換機構（200）は、第１および第２熱交換室（S11,S12）のうち、蒸発器となっている吸着熱交換器（101,102）が設けられた熱交換室（S11,S12）を通過した空気が調湿空間（S0）に供給され、凝縮器となっている吸着熱交換器（102,101）が設けられた熱交換室（S12,S11）に吸着剤を再生するための空気（この例では、加熱器（21）を通過した空気）が流通するように、空気の流れを切り換える。 <Switching mechanism>
In response to the control by the controller (20), the switching mechanism (200) changes the connection state of the first and second heat exchange chambers (S11, S12) to the first passage state (state shown by the solid line in FIG. 7). And a second passage state (state shown by a broken line in FIG. 7). Further, the switching mechanism (200) connects the first and second heat exchange chambers (S11, S12) when the four-way switching valve (105) is in the first connection state (the state shown by the solid line in FIG. 7). When the state is set to the first passage state and the four-way switching valve (105) is in the second connection state (the state indicated by the broken line in FIG. 7), the first and second heat exchange chambers (S11, S12) The connection state is set to the second passage state. That is, the switching mechanism (200) includes a heat exchange chamber (S11, S12) provided with an adsorption heat exchanger (101, 102) serving as an evaporator among the first and second heat exchange chambers (S11, S12). The air passing through the air is supplied to the humidity control space (S0), and the air for regenerating the adsorbent in the heat exchange chamber (S12, S11) provided with the adsorption heat exchanger (102, 101) serving as a condenser ( In this example, the air flow is switched so that the air passing through the heater (21) flows.
　なお、この例では、第１および第２熱交換室（S11,S12）の接続状態が第１通路状態である場合（すなわち、第１熱交換室（S11）が給気通路（P1）の一部として組み込まれている場合）に第１吸着熱交換器（101）を通過する空気の流通方向は、第１および第２熱交換室（S11,S12）の接続状態が第２通路状態である場合（すなわち、第１熱交換室（S11）が再生通路（P2）の一部として組み込まれている場合）に第１吸着熱交換器（101）を通過する空気の流通方向の逆方向となっている（所謂、対向流となっている）。第２吸着熱交換器（102）を通過する空気の流通方向についても同様である。このように、第１および第２吸着熱交換器（101,102）の各々を通過する空気の流通方向は、吸着熱交換器が蒸発器から凝縮器に（または、凝縮器から蒸発器に）切り換わると反転する。すなわち、切換機構（200）は、第１および第２吸着熱交換器（101,102）の各々を通過する空気の流通方向が、その吸着熱交換器（101,102）が蒸発器となっている場合とその吸着熱交換器（101,102）が凝縮器となっている場合とで逆方向となるように、空気の流れを切り換える。 In this example, when the connection state of the first and second heat exchange chambers (S11, S12) is the first passage state (that is, the first heat exchange chamber (S11) is a part of the air supply passage (P1). In the flow direction of the air passing through the first adsorption heat exchanger (101) in the case of being incorporated as a part), the connection state of the first and second heat exchange chambers (S11, S12) is the second passage state. In this case (that is, when the first heat exchange chamber (S11) is incorporated as part of the regeneration passage (P2)), the flow direction of the air passing through the first adsorption heat exchanger (101) is opposite. (So-called counter flow). The same applies to the flow direction of the air passing through the second adsorption heat exchanger (102). In this way, the flow direction of the air passing through each of the first and second adsorption heat exchangers (101, 102) switches the adsorption heat exchanger from the evaporator to the condenser (or from the condenser to the evaporator). And reverse. That is, the switching mechanism (200) has a case where the flow direction of the air passing through each of the first and second adsorption heat exchangers (101, 102) is the same as when the adsorption heat exchanger (101, 102) is an evaporator. The air flow is switched so that the adsorption heat exchanger (101, 102) is in the opposite direction to the case where it is a condenser.
　　〈吸着ブロック〉
　第１吸着ブロック（301）は、第１熱交換室（S11）において、第１吸着熱交換器（101）が蒸発器となっている場合に第１吸着熱交換器（101）の下流側（風下側）となる位置（すなわち、第１熱交換室（S11）が給気通路（P1）の一部として組み込まれている場合に第１吸着熱交換器（101）によって除湿された空気が通過する位置）に配置されている。 <Suction block>
The first adsorption block (301) is located downstream of the first adsorption heat exchanger (101) when the first adsorption heat exchanger (101) is an evaporator in the first heat exchange chamber (S11) ( Air dehumidified by the first adsorption heat exchanger (101) passes when the position becomes the leeward side (that is, when the first heat exchange chamber (S11) is incorporated as a part of the air supply passage (P1)) Position).
　第２吸着ブロック（302）は、第２熱交換室（S12）において、第２吸着熱交換器（102）が蒸発器となっている場合に第２吸着熱交換器（102）の下流側（風下側）となる位置（すなわち、第２熱交換室（S12）が給気通路（P1）の一部として組み込まれている場合に第２吸着熱交換器（102）によって除湿された空気が通過する位置）に配置されている。 The second adsorption block (302) is located downstream of the second adsorption heat exchanger (102) when the second adsorption heat exchanger (102) is an evaporator in the second heat exchange chamber (S12). Air dehumidified by the second adsorption heat exchanger (102) passes when the position becomes the leeward side (that is, when the second heat exchange chamber (S12) is incorporated as a part of the air supply passage (P1)) Position).
　なお、この例では、第１および第２吸着熱交換器（101,102）の各々を通過する空気の流通方向は、その吸着熱交換器（101,102）が蒸発器となっている場合とその吸着熱交換器（101,102）が凝縮器となっている場合とで逆方向となっている。したがって、第１および第２熱交換室（S11,S12）の接続状態が第１通路状態（図７の実線で示した状態）である場合に第１吸着熱交換器（101）の下流側となる位置は、第１および第２熱交換室（S11,S12）の接続状態が第２通路状態（図７の破線で示した状態）である場合に第１吸着熱交換器（101）の上流側となる位置（この例では、加熱器（21）と第１吸着熱交換器（101）との間となる位置）と同じ位置である。これと同様に、第１および第２熱交換室（S11,S12）の接続状態が第２通路状態（図７の破線で示した状態）である場合に第２吸着熱交換器（102）の下流側となる位置は、第１および第２熱交換室（S11,S12）の接続状態が第１通路状態（図１の実線で示した状態）である場合に第２吸着熱交換器（102）の上流側となる位置（この例では、加熱器（21）と第２吸着熱交換器（102）との間となる位置）と同じ位置である。すなわち、第１および第２熱交換室（S11,S12）の各々では、吸着ブロック（301,302）は、吸着熱交換器（101,102）が蒸発器となっている場合には、吸着熱交換器（101,102）の下流側に位置し、吸着熱交換器（101,102）が凝縮器となっている場合には、吸着熱交換器（101,102）の上流側に位置する。 In this example, the flow direction of the air passing through each of the first and second adsorption heat exchangers (101, 102) depends on whether the adsorption heat exchanger (101, 102) is an evaporator or the adsorption heat exchange. The direction is opposite to the case where the condenser (101, 102) is a condenser. Therefore, when the connection state of the first and second heat exchange chambers (S11, S12) is the first passage state (the state indicated by the solid line in FIG. 7), the downstream side of the first adsorption heat exchanger (101) Is located upstream of the first adsorption heat exchanger (101) when the connection state of the first and second heat exchange chambers (S11, S12) is the second passage state (the state indicated by the broken line in FIG. 7). This is the same position as the position (in this example, the position between the heater (21) and the first adsorption heat exchanger (101)). Similarly, when the connection state of the first and second heat exchange chambers (S11, S12) is the second passage state (the state indicated by the broken line in FIG. 7), the second adsorption heat exchanger (102) The position on the downstream side is the second adsorption heat exchanger (102 when the connection state of the first and second heat exchange chambers (S11, S12) is the first passage state (the state shown by the solid line in FIG. 1). ) On the upstream side (in this example, the position between the heater (21) and the second adsorption heat exchanger (102)). That is, in each of the first and second heat exchange chambers (S11, S12), the adsorption block (301, 302) has an adsorption heat exchanger (101, 102) when the adsorption heat exchanger (101, 102) is an evaporator. When the adsorption heat exchanger (101, 102) is a condenser, it is located upstream of the adsorption heat exchanger (101, 102).
　　〈除湿装置による除湿運転〉
　次に、図７を参照して、実施形態２の除湿装置（10）の除湿運転について説明する。実施形態１の除湿装置（10）と同様に、実施形態２の除湿装置（10）は、第１および第２除湿動作を所定の時間間隔（例えば、１０分間隔）で交互に繰り返す。 <Dehumidifying operation with dehumidifier>
Next, the dehumidifying operation of the dehumidifying device (10) of the second embodiment will be described with reference to FIG. Similar to the dehumidifying device (10) of the first embodiment, the dehumidifying device (10) of the second embodiment alternately repeats the first and second dehumidifying operations at predetermined time intervals (for example, every 10 minutes).
　　　《第１除湿動作》
　第１除湿動作では、圧縮機（103）が駆動され、膨張弁（104）の開度が調節され、四方切換弁（105）が第１接続状態（図７の実線で示した状態）となる。これにより、冷媒回路（100）は、第１吸着熱交換器（101）が蒸発器となり第２吸着熱交換器（102）が凝縮器となる第１冷凍サイクル動作を行う。また、切換機構（200）は、第１および第２熱交換室（S11,S12）の接続状態を第１通路状態（図７の実線で示した状態）に設定する。 << First dehumidifying operation >>
In the first dehumidifying operation, the compressor (103) is driven, the opening degree of the expansion valve (104) is adjusted, and the four-way switching valve (105) is in the first connection state (the state shown by the solid line in FIG. 7). . Thus, the refrigerant circuit (100) performs a first refrigeration cycle operation in which the first adsorption heat exchanger (101) serves as an evaporator and the second adsorption heat exchanger (102) serves as a condenser. Further, the switching mechanism (200) sets the connection state of the first and second heat exchange chambers (S11, S12) to the first passage state (the state indicated by the solid line in FIG. 7).
　　　　－給気通路における空気の流れ－
　給気通路（P1）に取り込まれた空気（この例では、室外空気（OA））は、冷却器（11）によって冷却除湿された後に、第１熱交換室（S11）に供給される。第１熱交換室（S11）に供給された空気は、蒸発器として機能している第１吸着熱交換器（101）を通過する。このとき、蒸発器として機能している第１吸着熱交換器（101）を通過する空気は、第１吸着熱交換器（101）の吸着剤に水分を奪われて湿度が低下するとともに、第１吸着熱交換器（101）を流れる冷媒の吸熱作用により冷却されて温度も低下する。次に、第１吸着熱交換器（101）によって除湿および冷却された空気は、第１吸着ブロック（301）を通過する。このとき、この空気中の水分が第１吸着ブロック（301）の吸着剤に吸着する。これにより、第１吸着熱交換器（101）によって除湿された空気は、第１吸着ブロック（301）によってさらに除湿される。第１吸着熱交換器（101）および第１吸着ブロック（301）を通過して除湿された空気は、供給空気（SA）として室内空間（S1）に供給される。 -Air flow in the air supply passage-
The air taken into the supply passage (P1) (in this example, outdoor air (OA)) is cooled and dehumidified by the cooler (11), and then supplied to the first heat exchange chamber (S11). The air supplied to the first heat exchange chamber (S11) passes through the first adsorption heat exchanger (101) functioning as an evaporator. At this time, the air passing through the first adsorption heat exchanger (101) functioning as an evaporator is deprived of moisture by the adsorbent of the first adsorption heat exchanger (101), and the humidity decreases. It is cooled by the endothermic action of the refrigerant flowing through the one adsorption heat exchanger (101), and the temperature also decreases. Next, the air dehumidified and cooled by the first adsorption heat exchanger (101) passes through the first adsorption block (301). At this time, moisture in the air is adsorbed on the adsorbent of the first adsorption block (301). Thereby, the air dehumidified by the first adsorption heat exchanger (101) is further dehumidified by the first adsorption block (301). The air dehumidified after passing through the first adsorption heat exchanger (101) and the first adsorption block (301) is supplied to the indoor space (S1) as supply air (SA).
　　　　－再生通路における空気の流れ－
　再生通路（P2）に取り込まれた空気（この例では、室内空気（RA））は、加熱器（21）によって加熱された後に、第２熱交換室（S12）に供給される。第２熱交換室（S12）に供給された空気は、第２吸着ブロック（302）を通過する。このとき、第２吸着ブロック（302）の吸着剤の水分が第２吸着ブロック（302）を通過する空気に放出される。これにより、第２吸着ブロック（302）の吸着剤が再生される。次に、第２吸着ブロック（302）によって加湿された空気は、凝縮器として機能している第２吸着熱交換器（102）を通過する。凝縮器として機能している第２吸着熱交換器（102）を通過する空気は、第２吸着熱交換器（102）の吸着剤から水分を付与されて湿度が上昇するとともに、第２吸着熱交換器（102）を流れる冷媒の放熱作用により加熱されて温度も上昇する。これにより、第２吸着熱交換器（102）の吸着剤が再生される。第２吸着熱交換器（102）および第２吸着ブロック（302）を通過した空気は、排出空気（EA）として室外空間に排出される。 -Air flow in the regeneration passage-
The air (in this example, room air (RA)) taken into the regeneration passage (P2) is heated by the heater (21) and then supplied to the second heat exchange chamber (S12). The air supplied to the second heat exchange chamber (S12) passes through the second adsorption block (302). At this time, the moisture of the adsorbent of the second adsorption block (302) is released to the air passing through the second adsorption block (302). Thereby, the adsorbent of the second adsorption block (302) is regenerated. Next, the air humidified by the second adsorption block (302) passes through the second adsorption heat exchanger (102) functioning as a condenser. The air passing through the second adsorption heat exchanger (102) functioning as a condenser is given moisture from the adsorbent of the second adsorption heat exchanger (102) to increase the humidity and the second adsorption heat. It is heated by the heat radiation action of the refrigerant flowing through the exchanger (102), and the temperature also rises. Thereby, the adsorbent of the second adsorption heat exchanger (102) is regenerated. The air that has passed through the second adsorption heat exchanger (102) and the second adsorption block (302) is exhausted to the outdoor space as exhaust air (EA).
　　　《第２除湿動作》
　第２除湿動作では、圧縮機（103）が駆動され、膨張弁（104）の開度が調節され、四方切換弁（105）が第２接続状態（図７の破線で示した状態）となる。これにより、冷媒回路（100）は、第１吸着熱交換器（101）が凝縮器となり第２吸着熱交換器（102）が蒸発器となる第２冷凍サイクル動作を行う。また、切換機構（200）は、第１および第２熱交換室（S11,S12）の接続状態を第２通路状態（図７の破線で示した状態）に設定する。 <Second dehumidifying operation>
In the second dehumidifying operation, the compressor (103) is driven, the opening degree of the expansion valve (104) is adjusted, and the four-way switching valve (105) is in the second connection state (the state indicated by the broken line in FIG. 7). . Thereby, the refrigerant circuit (100) performs a second refrigeration cycle operation in which the first adsorption heat exchanger (101) serves as a condenser and the second adsorption heat exchanger (102) serves as an evaporator. Further, the switching mechanism (200) sets the connection state of the first and second heat exchange chambers (S11, S12) to the second passage state (the state indicated by the broken line in FIG. 7).

　給気通路（P1）に取り込まれた空気（この例では、室外空気（OA））は、冷却器（11）によって冷却除湿された後に、第２熱交換室（S12）に供給される。第２熱交換室（S12）に供給された空気は、蒸発器として機能している第２吸着熱交換器（102）を通過する。このとき、蒸発器として機能している第２吸着熱交換器（102）を通過する空気は、第２吸着熱交換器（102）の吸着剤に水分を奪われて湿度が低下するとともに、第２吸着熱交換器（102）を流れる冷媒の吸熱作用により冷却されて温度も低下する。次に、第２吸着熱交換器（102）によって除湿および冷却された空気は、第２吸着ブロック（302）を通過する。このとき、この空気中の水分が第２吸着ブロック（302）の吸着剤に吸着する。これにより、第２吸着熱交換器（102）によって除湿された空気は、第２吸着ブロック（302）によってさらに除湿される。第２吸着熱交換器（102）および第２吸着ブロック（302）を通過して除湿された空気は、供給空気（SA）として室内空間（S1）に供給される。 -Air flow in the air supply passage-
The air taken into the supply passage (P1) (in this example, outdoor air (OA)) is cooled and dehumidified by the cooler (11), and then supplied to the second heat exchange chamber (S12). The air supplied to the second heat exchange chamber (S12) passes through the second adsorption heat exchanger (102) functioning as an evaporator. At this time, the air passing through the second adsorption heat exchanger (102) functioning as an evaporator is deprived of moisture by the adsorbent of the second adsorption heat exchanger (102), and the humidity decreases. The refrigerant is cooled by the endothermic action of the refrigerant flowing through the two-adsorption heat exchanger (102), and the temperature also decreases. Next, the air dehumidified and cooled by the second adsorption heat exchanger (102) passes through the second adsorption block (302). At this time, moisture in the air is adsorbed to the adsorbent of the second adsorption block (302). Thereby, the air dehumidified by the second adsorption heat exchanger (102) is further dehumidified by the second adsorption block (302). The air dehumidified after passing through the second adsorption heat exchanger (102) and the second adsorption block (302) is supplied to the indoor space (S1) as supply air (SA).
　　　　－再生通路における空気の流れ－
　再生通路（P2）に取り込まれた空気（この例では、室内空気（RA））は、加熱器（21）によって加熱された後に、第１熱交換室（S11）に供給される。第１熱交換室（S11）に供給された空気は、第１吸着ブロック（301）を通過する。このとき、第１吸着ブロック（301）の吸着剤の水分が第１吸着ブロック（301）を通過する空気に放出される。これにより、第１吸着ブロック（301）の吸着剤が再生される。次に、第１吸着ブロック（301）によって加湿された空気は、凝縮器として機能している第１吸着熱交換器（101）を通過する。このとき、凝縮器として機能している第１吸着熱交換器（101）を通過する空気は、第１吸着熱交換器（101）の吸着剤から水分を付与されて湿度が上昇するとともに、第１吸着熱交換器（101）を流れる冷媒の放熱作用により加熱されて温度も上昇する。これにより、第１吸着熱交換器（101）の吸着剤が再生される。第１吸着熱交換器（101）および第１吸着ブロック（301）を通過した空気は、排出空気（EA）として室外空間に排出される。 -Air flow in the regeneration passage-
The air taken into the regeneration passage (P2) (in this example, room air (RA)) is heated by the heater (21) and then supplied to the first heat exchange chamber (S11). The air supplied to the first heat exchange chamber (S11) passes through the first adsorption block (301). At this time, the moisture of the adsorbent of the first adsorption block (301) is released to the air passing through the first adsorption block (301). Thereby, the adsorbent of the first adsorption block (301) is regenerated. Next, the air humidified by the first adsorption block (301) passes through the first adsorption heat exchanger (101) functioning as a condenser. At this time, the air passing through the first adsorption heat exchanger (101) functioning as a condenser is given moisture from the adsorbent of the first adsorption heat exchanger (101), and the humidity rises. The temperature rises due to heating by the heat radiation action of the refrigerant flowing through the one adsorption heat exchanger (101). Thereby, the adsorbent of the first adsorption heat exchanger (101) is regenerated. The air that has passed through the first adsorption heat exchanger (101) and the first adsorption block (301) is exhausted to the outdoor space as exhaust air (EA).

　　〈実施形態２による効果〉
　実施形態２の除湿装置（10）では、第１および第２熱交換室（S11,S12）に第１および第２吸着ブロック（301,302）を追加することにより、第１および第２熱交換室（S11,S12）における空気の除湿量を増加させることができる。 <Effects of Embodiment 2>
In the dehumidifying apparatus (10) of Embodiment 2, the first and second heat exchange chambers (301, 302) are added to the first and second heat exchange chambers (S11, S12), thereby The amount of dehumidified air in S11 and S12) can be increased.
　また、第１熱交換室（S11）が給気通路（P1）に組み込まれている場合に第１吸着熱交換器（101）によって除湿された空気が通過する位置に第１吸着ブロック（301）を配置することにより、第１吸着熱交換器（101）によって除湿および冷却された空気を、第１吸着ブロック（301）に供給することができる。これにより、第１吸着ブロック（301）において吸着剤への水分の吸着を促進させることができる。これと同様に、第２熱交換室（S12）が給気通路（P1）に組み込まれている場合に、第２吸着熱交換器（102）によって除湿および冷却された空気を、第２吸着ブロック（302）に供給することができるので、第２吸着ブロック（302）において吸着剤への水分の吸着を促進させることができる。すなわち、第１および第２熱交換室（S11,S12）の各々において、吸着熱交換器（101,102）が蒸発器となっている場合に吸着熱交換器（101,102）の下流側となる位置に吸着ブロック（301,302）を配置することにより、吸着熱交換器（101,102）によって除湿および冷却された空気を吸着ブロック（301,302）に供給することができるので、吸着ブロック（301,302）の吸着剤への水分の吸着を促進させることができる。 In addition, when the first heat exchange chamber (S11) is incorporated in the air supply passage (P1), the first adsorption block (301) is located at a position where the air dehumidified by the first adsorption heat exchanger (101) passes. The air dehumidified and cooled by the first adsorption heat exchanger (101) can be supplied to the first adsorption block (301). Thereby, adsorption | suction of the water | moisture content to adsorption agent can be accelerated | stimulated in a 1st adsorption | suction block (301). Similarly, when the second heat exchange chamber (S12) is incorporated in the air supply passage (P1), the air dehumidified and cooled by the second adsorption heat exchanger (102) is transferred to the second adsorption block. Since it can be supplied to (302), the adsorption of moisture to the adsorbent can be promoted in the second adsorption block (302). That is, in each of the first and second heat exchange chambers (S11, S12), when the adsorption heat exchanger (101, 102) is an evaporator, the adsorption is performed at a position downstream of the adsorption heat exchanger (101, 102). By disposing the block (301,302), the air dehumidified and cooled by the adsorption heat exchanger (101,102) can be supplied to the adsorption block (301,302), so that the moisture to the adsorbent of the adsorption block (301,302) can be supplied. Adsorption can be promoted.
　以上のように、第１および第２熱交換室（S11,S12）における空気の除湿量を増加させることができ、さらに、吸着ブロック（301,302）において吸着剤への水分の吸着を促進させることができるので、除湿装置（10）の除湿能力を向上させることができる。 As described above, the amount of air dehumidified in the first and second heat exchange chambers (S11, S12) can be increased, and the adsorption of moisture to the adsorbent can be promoted in the adsorption block (301, 302). Therefore, the dehumidifying capacity of the dehumidifying device (10) can be improved.
　また、除湿装置（10）の除湿能力を向上させるために冷媒回路（100）の圧縮機（103）の回転数を増加させなくてもよいので、除湿装置（10）の消費電力の増大を抑制することができる。 Moreover, since it is not necessary to increase the rotation speed of the compressor (103) of the refrigerant circuit (100) in order to improve the dehumidifying capacity of the dehumidifying device (10), the increase in power consumption of the dehumidifying device (10) is suppressed. can do.
　また、実施形態２では、第１および第２熱交換室（S11,S12）の各々において、吸着ブロック（301,302）は、吸着熱交換器（101,102）が蒸発器となっている場合には、吸着熱交換器（101,102）の下流側に位置し、吸着熱交換器（101,102）が凝縮器となっている場合には、吸着熱交換器（101,102）の上流側に位置する。したがって、第１および第２熱交換室（S1,S12）のうち凝縮器となっている吸着熱交換器（101,102）が設けられた熱交換室（S11,S12）に、加熱器（21）を通過した空気を流通させることにより、その熱交換室（S11,S12）において吸着熱交換器（101,102）の上流側に位置している吸着ブロック（301,302）に、加熱器（21）によって加熱された空気を供給することができる。これにより、吸着ブロック（301,302）の吸着剤の再生を促進させることができる。 In Embodiment 2, in each of the first and second heat exchange chambers (S11, S12), the adsorption block (301, 302) is adsorbed when the adsorption heat exchanger (101, 102) is an evaporator. When located on the downstream side of the heat exchanger (101, 102) and the adsorption heat exchanger (101, 102) is a condenser, it is located on the upstream side of the adsorption heat exchanger (101, 102). Therefore, the heater (21) is placed in the heat exchange chamber (S11, S12) provided with the adsorption heat exchanger (101, 102) serving as a condenser among the first and second heat exchange chambers (S1, S12). By circulating the air that passed through, it was heated by the heater (21) to the adsorption block (301,302) located upstream of the adsorption heat exchanger (101,102) in the heat exchange chamber (S11, S12) Air can be supplied. Thereby, regeneration of the adsorbent of the adsorption block (301, 302) can be promoted.
　なお、実施形態１では、第１吸着熱交換器（101）が凝縮器となっている場合、第１吸着ブロック（301）は、第１熱交換室（S11）において第１吸着熱交換器（101）の下流側に位置しているので、第１吸着熱交換器（101）を通過した空気が第１吸着ブロック（301）に供給される。この場合、第１吸着熱交換器（101）を通過して第１吸着ブロック（301）に供給される空気は、第１吸着熱交換器（101）によって加熱されるだけでなく加湿もされることになる。第２吸着ブロック（302）についても同様である。 In the first embodiment, when the first adsorption heat exchanger (101) is a condenser, the first adsorption block (301) is the first adsorption heat exchanger (S11) in the first heat exchange chamber (S11). 101), the air that has passed through the first adsorption heat exchanger (101) is supplied to the first adsorption block (301). In this case, the air that passes through the first adsorption heat exchanger (101) and is supplied to the first adsorption block (301) is not only heated but also humidified by the first adsorption heat exchanger (101). It will be. The same applies to the second adsorption block (302).
　一方、実施形態２では、第１吸着熱交換器（101）が凝縮器となっている場合、第１吸着ブロック（301）は、第１熱交換室（S11）において第１吸着熱交換器（101）の上流側に位置し、加熱器（21）によって加熱された空気が第１吸着ブロック（301）に供給される。この場合、加熱器（21）を通過して第１吸着ブロック（301）に供給される空気は、加熱器（21）によって加熱されるが加湿はされない。したがって、実施形態１よりも、第１吸着ブロック（301）の吸着剤の再生を促進させることができ、第１吸着ブロック（301）における吸着能力をより向上することができる。第２吸着ブロック（302）についても同様である。 On the other hand, in Embodiment 2, when the first adsorption heat exchanger (101) is a condenser, the first adsorption block (301) is the first adsorption heat exchanger (S11) in the first heat exchange chamber (S11). 101), the air heated by the heater (21) is supplied to the first adsorption block (301). In this case, the air that passes through the heater (21) and is supplied to the first adsorption block (301) is heated by the heater (21) but is not humidified. Therefore, the regeneration of the adsorbent in the first adsorption block (301) can be promoted more than in the first embodiment, and the adsorption capacity in the first adsorption block (301) can be further improved. The same applies to the second adsorption block (302).
　また、第１吸着熱交換器（101）と間隔をおいて第１吸着ブロック（301）を配置することにより、第１吸着ブロック（301）における温度分布の偏りや空気偏流を抑制することができる。第２吸着ブロック（302）についても同様である。このように、第１および第２吸着ブロック（301,302）において温度分布の偏りや空気偏流を抑制することができるので、第１および第２吸着ブロック（301,302）における吸着能力および再生能力の低下を抑制することができる。 Further, by disposing the first adsorption block (301) at a distance from the first adsorption heat exchanger (101), it is possible to suppress temperature distribution deviation and air drift in the first adsorption block (301). . The same applies to the second adsorption block (302). As described above, since the temperature distribution and air drift can be suppressed in the first and second adsorption blocks (301, 302), the decrease in adsorption capacity and regeneration capacity in the first and second adsorption blocks (301, 302) is suppressed. can do.

　また、冷却空気通路（P80）を流れる空気を給気通路（P1）の中途部に供給することにより、冷却空気通路（P80）において冷却された空気を用いて、蒸発器となっている吸着熱交換器（101,102）が設けられた熱交換室（S11,S12）を通過した空気の温度を低下させることができる。すなわち、吸着ブロック（101,102）に残った再生時の余熱や吸着ブロック（101,102）における吸着熱によって温度上昇した空気の温度を低下させることができる。 In addition, by supplying the air flowing through the cooling air passage (P80) to the middle of the air supply passage (P1), the adsorption heat that is the evaporator using the air cooled in the cooling air passage (P80) The temperature of the air that has passed through the heat exchange chambers (S11, S12) provided with the exchangers (101, 102) can be reduced. That is, it is possible to reduce the temperature of the air that has increased in temperature due to the residual heat remaining in the adsorption block (101, 102) during regeneration or the adsorption heat in the adsorption block (101, 102).
　また、給気通路（P1）から供給された空気の一部がパージ通路（P73）とロータ再生通路（P72）と再生通路（P2）とを順に通過するので、蒸発器となっている吸着熱交換器（101,102）が設けられた熱交換室（S11,S12）を通過した空気（すなわち、除湿装置（10）において除湿された空気）の一部を、吸着ロータ（70）の吸着剤および凝縮器となっている吸着熱交換器（102,101）の吸着剤の再生に利用することができる。これにより、吸着剤の再生を促進させることができる。 Also, a part of the air supplied from the supply passage (P1) passes through the purge passage (P73), the rotor regeneration passage (P72), and the regeneration passage (P2) in this order, so that the adsorption heat acting as an evaporator Part of the air (that is, the air dehumidified in the dehumidifier (10)) that has passed through the heat exchange chambers (S11, S12) in which the exchangers (101, 102) are provided, is adsorbed and condensed in the adsorption rotor (70). It can be used for the regeneration of the adsorbent of the adsorption heat exchanger (102, 101) serving as a vessel. Thereby, regeneration of adsorbent can be promoted.
　（その他の実施形態）
　以上の説明において、第１吸着ブロック（301）が第１吸着熱交換器（101）と間隔をおいて配置され第２吸着ブロック（302）が第２吸着熱交換器（102）と間隔をおいて配置されている場合を例に挙げて説明したが、第１吸着ブロック（301）は、第１吸着熱交換器（101）と接触するように配置されてもよく、第２吸着ブロック（302）は、第２吸着熱交換器（102）と接触するように配置されてもよい。このように構成することにより、第１吸着熱交換器（101）と第１吸着ブロック（301）との間における熱伝導を促進させることができるとともに第２吸着熱交換器（102）と第２吸着ブロック（302）との間における熱伝導を促進させることができる。例えば、第１熱交換室（S11）が給気通路（P1）に組み込まれている場合には、第１吸着熱交換器（101）を流れる冷媒の吸熱作用によって第１吸着ブロック（301）を冷却することができ、第１熱交換室（S11）が再生通路（P2）に組み込まれている場合には、第１吸着熱交換器（101）を流れる冷媒の放熱作用によって第１吸着ブロック（301）を加熱することができる。これにより、第１および第２吸着ブロック（301,302）において吸着剤への水分の吸着および吸着剤の再生を促進させることができる。 (Other embodiments)
In the above description, the first adsorption block (301) is spaced from the first adsorption heat exchanger (101), and the second adsorption block (302) is spaced from the second adsorption heat exchanger (102). However, the first adsorption block (301) may be arranged in contact with the first adsorption heat exchanger (101), and the second adsorption block (302) may be disposed. ) May be placed in contact with the second adsorption heat exchanger (102). With this configuration, heat conduction between the first adsorption heat exchanger (101) and the first adsorption block (301) can be promoted, and the second adsorption heat exchanger (102) and the second adsorption heat exchanger (102) can be promoted. Heat conduction with the adsorption block (302) can be promoted. For example, when the first heat exchange chamber (S11) is incorporated in the air supply passage (P1), the first adsorption block (301) is removed by the heat absorption action of the refrigerant flowing through the first adsorption heat exchanger (101). When the first heat exchange chamber (S11) is incorporated in the regeneration passage (P2), the first adsorption block (101) can be cooled by the heat radiation action of the refrigerant flowing through the first adsorption heat exchanger (101). 301) can be heated. Thereby, in the first and second adsorption blocks (301, 302), it is possible to promote the adsorption of moisture to the adsorbent and the regeneration of the adsorbent.
　また、複数の除湿装置（10）を互いに並列に接続することによって１つの除湿ユニットを構成してもよい。例えば、図２（または、図７）に示した除湿装置（10）を上下に複数段積み重ねて各除湿装置（10）の開口（具体的には、吸着側吸込口（51），再生側吸込口（52），給気口（53），排気口（54））を種別毎に共通に接続することによって１つの除湿ユニットを構成してもよい。 Further, one dehumidifying unit may be configured by connecting a plurality of dehumidifying devices (10) in parallel with each other. For example, the dehumidifiers (10) shown in FIG. 2 (or FIG. 7) are stacked in a plurality of stages and opened in each dehumidifier (10) (specifically, suction side suction port (51), regeneration side suction) One dehumidifying unit may be configured by commonly connecting the mouth (52), the air inlet (53), and the air outlet (54) for each type.
　なお、除湿装置（10）に第１および第２吸着ブロック（301,302）を追加せずに、第１および第２吸着熱交換器（101,102）のサイズを大きくすることによって除湿装置（10）の除湿能力を向上させることが考えられる。すなわち、吸着熱交換器のサイズを大きくすることにより、蒸発器として機能している吸着熱交換器において冷媒の吸熱作用を高くすることができる。これにより、吸着熱交換器内の空気の温度を低下させることができるとともに、吸着剤の吸着熱による空気の温度上昇を抑制することができる。また、吸着熱交換器内において空気の温度が低くなるほど、空気の飽和水蒸気量が低くなって空気中の水分が吸着剤に吸着しやすくなる傾向にある。このように、冷媒の吸熱作用により、空気中から吸着剤への水分の吸着を促進させることができる。 The dehumidifier (10) is dehumidified by increasing the size of the first and second adsorption heat exchangers (101,102) without adding the first and second adsorption blocks (301,302) to the dehumidifier (10). It is possible to improve ability. That is, by increasing the size of the adsorption heat exchanger, the heat absorption effect of the refrigerant can be increased in the adsorption heat exchanger functioning as an evaporator. Thereby, while the temperature of the air in an adsorption heat exchanger can be reduced, the temperature rise of the air by the adsorption heat of adsorption agent can be controlled. Further, the lower the temperature of the air in the adsorption heat exchanger, the lower the saturated water vapor amount of the air, and the moisture in the air tends to be easily adsorbed by the adsorbent. Thus, the adsorption of moisture from the air to the adsorbent can be promoted by the endothermic action of the refrigerant.
　ところで、蒸発器として機能している吸着熱交換器の内部では、上流側から下流側へ向かうに連れて、空気の温度と空気中の水分量が少なくなっていく。すなわち、吸着熱交換器の内部では、上流側において除湿および冷却された空気が下流側に供給されることになる。そのため、吸着熱交換器内の下流側では、冷媒の吸熱作用によって空気の温度が低下して空気の飽和水蒸気量が低下したとしても、空気中の水分量が少なくなっているので、空気中から吸着剤への水分の吸着を促進させにくい。また、空気中の水分量が少なくなるほど、吸着剤における吸着熱の発生量が少なくなる。そのため、吸着熱交換器の下流側では、冷媒の吸熱作用によって吸着剤が過剰に冷却されることになる。 By the way, inside the adsorption heat exchanger functioning as an evaporator, the air temperature and the amount of moisture in the air decrease from the upstream side toward the downstream side. That is, inside the adsorption heat exchanger, air dehumidified and cooled on the upstream side is supplied to the downstream side. Therefore, on the downstream side in the adsorption heat exchanger, even if the temperature of the air decreases due to the endothermic action of the refrigerant and the amount of saturated water vapor in the air decreases, the amount of moisture in the air decreases. It is difficult to promote the adsorption of moisture to the adsorbent. Further, the amount of heat of adsorption in the adsorbent decreases as the amount of moisture in the air decreases. Therefore, on the downstream side of the adsorption heat exchanger, the adsorbent is excessively cooled by the endothermic action of the refrigerant.
　以上のように、吸着熱交換器のサイズを大きくしたとしても、吸着熱交換器内の上流側から下流側へ向かうに連れて、冷媒の吸熱作用による効果（吸着剤への水分の吸着を促進させる効果，吸着熱を取り除く効果）が薄れていくので、除湿装置（10）の除湿能力を効果的に向上させることが困難である。 As described above, even if the size of the adsorption heat exchanger is increased, the effect due to the endothermic action of the refrigerant (accelerating the adsorption of moisture to the adsorbent as it moves from the upstream side to the downstream side in the adsorption heat exchanger) Therefore, it is difficult to effectively improve the dehumidifying capacity of the dehumidifying device (10).
　また、空気中から吸着剤への水分の吸着を促進させる手段として、空気と吸着剤との接触面積を大きくすることが考えられる。すなわち、空気と吸着剤との接触面積が大きくなるほど、空気中の水分が吸着剤に吸着しやすくなる。特に、空気中の水分量が少なくなっている場合、冷媒の吸熱作用によって空気の温度を低下させる場合よりも、空気と吸着剤との接触面積を大きくする場合のほうが、空気中から吸着剤への水分の吸着を促進させることができる。また、吸着ブロックには冷媒配管などの部品を設けなくてもよいので、構造上、吸着ブロックは、吸着熱交換器よりも表面積（空気との接触面積）を大きくしやすい。したがって、蒸発器として機能している吸着熱交換器の下流側となる位置（吸着熱交換器によって除湿および冷却された空気が通過する位置）に吸着ブロックを配置することにより、吸着熱交換器の下流側において空気と吸着剤との接触面積を大きくすることができるので、吸着熱交換器のサイズを大きくする場合よりも、除湿装置（10）の除湿能力を効果的に向上させることができる。 Also, as a means for promoting the adsorption of moisture from the air to the adsorbent, it is conceivable to increase the contact area between air and the adsorbent. That is, the larger the contact area between air and the adsorbent, the easier it is for moisture in the air to be adsorbed on the adsorbent. In particular, when the amount of moisture in the air is low, the case where the contact area between the air and the adsorbent is increased from the air to the adsorbent than when the temperature of the air is lowered by the endothermic action of the refrigerant. Adsorption of moisture can be promoted. Moreover, since it is not necessary to provide components, such as refrigerant | coolant piping, in an adsorption | suction block, it is easy to enlarge a surface area (contact area with air) from an adsorption | suction heat exchanger on a structure. Therefore, by arranging the adsorption block at the position downstream of the adsorption heat exchanger functioning as an evaporator (the position where the air dehumidified and cooled by the adsorption heat exchanger passes), the adsorption heat exchanger Since the contact area between the air and the adsorbent can be increased on the downstream side, the dehumidifying ability of the dehumidifying device (10) can be effectively improved as compared with the case of increasing the size of the adsorption heat exchanger.
　なお、一般的に、吸着剤の再生動作（吸着剤から空気中への水分の放出）は、吸着剤の吸着動作（空気中から吸着剤への水分の吸着）よりも、反応速度が速くなっている。したがって、第１および第２熱交換室（S11,S12）のうち蒸発器となっている吸着熱交換器（101,102）が設けられた熱交換室（S11,S12）を通過する空気の風量は、凝縮器となっている吸着熱交換器（102,101）が設けられた熱交換室（S12,S11）を通過する空気の風量よりも多くなっていてもよいし、同等となっていてもよい。 In general, the adsorbent regeneration operation (release of moisture from the adsorbent into the air) has a faster reaction rate than the adsorbent adsorption operation (adsorption of moisture from the air into the adsorbent). ing. Therefore, the air volume of the air passing through the heat exchange chamber (S11, S12) provided with the adsorption heat exchanger (101, 102) serving as an evaporator among the first and second heat exchange chambers (S11, S12) is: The amount of air passing through the heat exchange chamber (S12, S11) provided with the adsorption heat exchanger (102, 101) serving as a condenser may be larger or the same.
　また、実施形態２（図７）および実施形態２の変形例（図１０）では、再生通路（P2）に加熱器（21）が設けられている場合を例に挙げたが、除湿システム（1）は、加熱器（21）を備えていなくてもよい。例えば、再生通路（P2）に供給される空気（すなわち、凝縮器となっている吸着熱交換器（102,101）が設けられた熱交換室（S12,S11）に供給される空気）の温度が、給気通路（P1）に供給される空気（すなわち、蒸発器となっている吸着熱交換器（101,102）が設けられた熱交換室（S11,S12）に供給される空気）の温度よりも高く、これらの空気の温度差が所定の温度差（具体的には、吸着剤を再生させることができる温度差）よりも大きくなっている場合、加熱器（21）を省略してもよい。 Further, in the second embodiment (FIG. 7) and the modification of the second embodiment (FIG. 10), the case where the heater (21) is provided in the regeneration passage (P2) is taken as an example, but the dehumidification system (1 ) May not include the heater (21). For example, the temperature of the air supplied to the regeneration passage (P2) (that is, the air supplied to the heat exchange chamber (S12, S11) provided with the adsorption heat exchanger (102, 101) serving as a condenser) is Higher than the temperature of the air supplied to the supply passage (P1) (that is, the air supplied to the heat exchange chamber (S11, S12) provided with the adsorption heat exchanger (101, 102) serving as an evaporator) When the temperature difference between these airs is larger than a predetermined temperature difference (specifically, a temperature difference at which the adsorbent can be regenerated), the heater (21) may be omitted.
　また、以上の実施形態を適宜組み合わせて実施してもよい。以上の実施形態は、本質的に好ましい例示であって、この発明、その適用物、あるいはその用途の範囲を制限することを意図するものではない。 Further, the above embodiments may be combined as appropriate.
