In the adsorption element (81, 82, 165) that is the target of the adsorption operation, the moisture in the supplied first air is adsorbed by the adsorbent and the first air is dehumidified. The adsorption element (81, 82, 165) that is the target of the regenerating operation is heated by the second air heated by the heater (72, 166). Then, moisture is desorbed from the heated adsorbing elements (81, 82, 165), and the desorbed moisture is given to the second air to humidify the second air.

  In the tenth aspect of the invention, the refrigerant circuit that performs the refrigeration cycle is provided in the humidity control device, and the condenser (72) of the refrigerant circuit constitutes a heater. When starting to perform the humidification operation, the humidity control apparatus starts the humidification operation after performing the preheating operation.

The cooling heat medium absorbs heat. In the adsorption heat exchanger (241, 242) that is the target of the regeneration operation, the adsorbent is heated by the heating heat medium in the heat transfer tube. Then, moisture desorbed from the heated adsorbent is given to the second air, and the second air is humidified.

  In the twelfth aspect, when starting to perform the humidification operation, the humidity control apparatus starts the humidification operation after performing the preheating operation. During the preheating operation, the adsorption heat exchanger (241, 242) is heated by the heating heat medium introduced into the heat transfer tube. Further, during the preheating operation, since the supply of air to the room is stopped, the air that has passed through the adsorption heat exchanger (241, 242) that has not been sufficiently warmed is not supplied to the room. And the humidity control apparatus of this invention raises the temperature of adsorption heat exchanger (241,242) in advance by preheating operation | movement, and starts a humidification operation | movement after that.

  In the present invention, when the humidity control device is stopped, the open / close dampers (21,..., 31,...) Are kept closed so that the space between the room and the outside is blocked, and the outdoor air enters the room. Be blocked. For this reason, for example, in winter, outdoor air dried at a low temperature while the humidity control device is stopped can be prevented from entering the room through the casing (10,...). It is possible to avoid excessive decrease in temperature and humidity. Also, during the summer season, it is possible to prevent the outdoor air that is humid at high temperatures from entering the room through the casing (10,...) While the humidity control device is stopped. And excessive rise in humidity can be avoided.

  As described above, according to the present invention, it is possible to prevent the outdoor air from entering the room while the humidity control apparatus is stopped, and it is possible to avoid the deterioration of the indoor environment due to the intrusion. Therefore, according to the present invention, it is possible to reduce the deterioration of the indoor environment until the humidity control device is started next time, and it is possible to shorten the time required from the start of the humidity control device until the room returns to a comfortable state. it can.

  In the third and fourth inventions, when the humidity control apparatus is stopped, the adsorbing member (81,...) And the outdoor flow path (65) are closed by the outdoor open / close dampers (31,. , 65, ...) is blocked. Here, if low-temperature outdoor air enters the adsorption member (81,...) In winter, the moisture retained on the adsorption member (81,...) May be frozen. On the other hand, in these inventions, outdoor air is prevented from entering the adsorption member (81,...) While the humidity control apparatus is stopped. Therefore, according to these inventions, freezing of moisture in the adsorption member (81,...) Can be prevented while the humidity control apparatus is stopped in winter, and the reliability of the humidity control apparatus can be improved.

  Further, according to the third and fourth inventions, outdoor air containing dust can be prevented from entering the adsorption member (81,...) While the humidity control apparatus is stopped. Therefore, according to these inventions, it is possible to prevent the adsorption member (81,...) From being contaminated by dust in the outdoor air while the humidity control device is stopped, and the lifetime of the adsorption member (81,...). Can be extended.

  In the fifth aspect of the present invention, moisture is stored in advance in the adsorption member (81, ...) before the humidity control apparatus stops. For this reason, when resuming the humidification operation, the air supplied to the room can be humidified using the moisture stored in the adsorption member (81,...) Before the stop. Therefore, according to the present invention, air containing a relatively large amount of water can be supplied into the room immediately after resuming the humidifying operation, and the time required from the start of the humidity control device to the comfortable state of the room is further increased. It can be shortened.

  Further, according to the fifth aspect of the present invention, the aldehyde, which is an odorous substance, can be removed from the adsorbing member (81,...) By the operation performed before stopping. For this reason, the situation where the aldehyde desorbed from the adsorbing member (81,...) Flows into the room after resuming operation can be avoided, and indoor comfort can be ensured.

  In the sixth aspect, the adsorption member (81,...) Is dried in advance before the humidity control apparatus stops. For this reason, when restarting the dehumidifying operation, it is possible to sufficiently dehumidify the air supplied to the room immediately after resuming the dehumidifying operation by using the adsorbing member (81,...)

Therefore, according to the present invention, relatively dry air can be supplied into the room immediately after resumption of the dehumidifying operation, and the time required from the start of the humidity control device to the comfortable state of the room can be further shortened. Can do.

  Further, according to the sixth aspect, ammonia that is an odorous substance can be removed from the adsorbing member (81,...) By an operation performed before stopping. For this reason, it is possible to avoid a situation in which ammonia desorbed from the adsorption member (81,...) Flows into the room after resuming operation, and to ensure indoor comfort.

  Here, when a relatively large amount of moisture remains in the adsorption member (81,...) While the humidity control apparatus is stopped, mold is generated in the adsorption member (81,...), And the adsorption member ( 81, ...) is accelerated. On the other hand, according to the sixth invention, since the adsorbing member (81,...) Is dried in advance before the stop, the adsorbing member (81,. It becomes possible to keep it. Therefore, according to this invention, generation | occurrence | production of the mold | fungi in the adsorption | suction member (81, ...) in the stop of a humidity control apparatus can be suppressed, and the lifetime of an adsorption | suction member (81, ...) can be extended.

  In the seventh aspect, before the dehumidifying operation is stopped, an operation of supplying air with relatively low humidity to the exhaust duct is performed. Here, if high-humidity air stays in the exhaust duct while the humidity control device is stopped, it may be cooled by the outside air to cause dew condensation in the exhaust duct or mold in the exhaust duct. . On the other hand, if the operation | movement which supplies the air taken in like this invention as it is to an exhaust duct is performed before a stop, the inside of an exhaust duct can be kept dry while the humidity control apparatus stops. Therefore, according to the present invention, it is possible to prevent dew condensation and mold generation in the exhaust duct while the humidity control apparatus is stopped, and to reduce deterioration of the exhaust duct due to them.

  In the eighth aspect of the invention, the air staying in the casing (10,...) While being stopped by the purge operation is discharged outside the room, and thereafter, the dehumidifying operation or the humidifying operation is started. Here, during operation of the humidity control apparatus, odor components such as ammonia may be adsorbed by the adsorbing member (81,...). If the humidity control device is stopped while the odor component is adsorbed on the adsorption member (81, ...), the odor component is gradually detached from the adsorption member (81, ...) while the humidity control device is stopped. There is a possibility that the odor component which has been collected stays in the casing (10,...). For this reason, if the dehumidifying operation or the humidifying operation is started immediately after the start of the humidity control device, the odor component staying in the casing (10,...) Is sent into the room, and the indoor comfort may be impaired.

  On the other hand, in the said 8th invention, the purge operation | movement is performed before the start of a dehumidification operation or a humidification operation, and the air which stayed in the casing (10, ...) is discharged | emitted outdoor. Therefore, according to the present invention, it is possible to prevent the odorous substance staying in the casing (10,...) During the stoppage from flowing into the room and to ensure the comfort in the room.

  In the tenth aspect of the invention, the preheating operation for preheating the condenser (72) through which the second air supplied to the room passes during the humidifying operation is performed, and thereafter the humidifying operation is started. In the twelfth aspect of the invention, a preheating operation for preheating the adsorption heat exchanger (241, 242) through which the second air supplied to the room passes during the humidifying operation is performed, and then the humidifying operation is started. Here, when the humidification operation is started in winter, if the humidification operation is started with the condenser (72) and the adsorption heat exchanger (241,242) not sufficiently warm, cold air is supplied to the room and There is a risk of impairing comfort. On the other hand, according to these inventions, the humidification operation can be started after the temperature of the condenser (72) and the adsorption heat exchanger (241, 242) is sufficiently increased, thereby ensuring indoor comfort. Can do.

-Operation when stopping-
During the dehumidifying operation or humidifying operation of the humidity control apparatus, the outdoor air taken into the casing (10) is supplied to the room while the taken indoor air is discharged to the outside. ), The interior and the exterior communicate with each other. For this reason, if the dampers (21,..., 31,...) Are kept in operation when the operation is stopped, outdoor air enters the room through the casing (10) during the stop. The indoor environment may be worse than necessary.

  Therefore, as shown in FIG. 7, the humidity control apparatus includes all the dampers (31,...) Constituting the indoor open / close dampers and all the dampers (21,...) Constituting the outdoor open / close dampers. Close when you stop.

  Specifically, the humidity control apparatus includes a first left damper (31), a second left damper (32), a first upper left damper (33), a first lower left damper (34), a second upper left damper (35), and When the second lower left damper (36) is stopped, it is set to the closed state, and these dampers (31,...) Are kept closed even during the stop. Thus, the first adsorption element (81) and the second adsorption element (82) are separated from the upper left channel (67) and the lower left channel (68), which are indoor side channels.

  Further, the humidity control apparatus includes a first right damper (21), a second right damper (22), a first upper right damper (23), a first lower right damper (24), a second upper right damper (25), and a first 2 When the lower right damper (26) is stopped, it is set to a closed state, and these dampers (21,...) Are kept closed even during the stop. Thus, the first adsorption element (81) and the second adsorption element (82) are separated from the upper right channel (65) and the lower right channel (66), which are outdoor channels.

  Thus, while the humidity control apparatus is stopped, in the casing (10), the upper right channel (65), the lower right channel (66), the upper left channel (67), and the lower left channel ( 68), the first adsorption element (81) and the second adsorption element (82) are isolated. In other words, outdoor air can only enter the upper right channel (65) and lower right channel (66), and indoor air can only enter the upper left channel (67) and lower left channel (68). The room and the outdoor are blocked.

-Effect of Embodiment 1-
In the humidity control apparatus of this embodiment, during the stop, all the dampers (21,..., 31,...) Constituting the indoor side and outdoor side open / close dampers are shut off so that the room and the outdoor are blocked. The closed state is maintained, and the entry of outdoor air into the room is prevented. For this reason, for example, in winter, outdoor air dried at a low temperature while the humidity control device is stopped can be prevented from entering the room through the casing (10). And excessive reduction of humidity can be avoided. Also, during the summer season, it is possible to prevent outdoor air humid at high temperatures from entering the room through the casing (10) while the humidity control device is stopped. Can be prevented from rising excessively.

Therefore, according to this embodiment, it is possible to reduce the deterioration of the indoor environment until the humidity control device is started next time, and to shorten the time required from the start of the humidity control device to the return of the room to a comfortable state. Can do.

  Here, if low temperature outdoor air enters the adsorbing member in winter, the moisture held in the adsorbing member may be frozen. On the other hand, in this embodiment, all the dampers (21,...) Constituting the outdoor open / close damper are held closed during the stop, and the first adsorption element (81) and the second adsorption element (82). Intrusion of outdoor air into the water is prevented. Therefore, according to the present embodiment, moisture can be prevented from freezing in the adsorption element (81, 82) while the humidity control apparatus is stopped in winter, and the reliability of the humidity control apparatus can be improved.

  If the outdoor air contains a relatively large amount of odor components, the outdoor air containing the odor components enters the adsorption element (81, 82) while the humidity control device is stopped, and the odor components in the outdoor air. May be adsorbed by the adsorption element (81, 82). When the humidity control apparatus resumes operation, the odor component adsorbed by the adsorption element (81, 82) is sent into the room, which may impair indoor comfort. On the other hand, in this embodiment, all the dampers (21,...) Constituting the outdoor open / close damper are held closed during the stop, and the first adsorption element (81) and the second adsorption element (82). Intrusion of outdoor air into the water is prevented. Therefore, according to the present embodiment, it is possible to prevent the adsorption of the odor component to the adsorption element (81, 82) even while the humidity control apparatus is stopped, and to ensure the comfort in the room after the operation is resumed.

  In addition, when the outdoor air is humid, such as during the rainy season, outdoor air containing a large amount of moisture enters the adsorption element (81, 82) while the humidity control device is stopped, and the adsorption element (81, 82). ) Becomes damp and mold may be generated in the adsorption element (81, 82). On the other hand, in this embodiment, all the dampers (21,...) Constituting the outdoor open / close damper are held closed during the stop, and the first adsorption element (81) and the second adsorption element (82). Intrusion of outdoor air into the water is prevented. Therefore, according to the present embodiment, generation of mold in the adsorption element (81, 82) due to the intrusion of moist outside air can be prevented while the humidity control device is stopped, and the adsorption element (81, 82) Can extend the lifespan.

  Further, according to the present embodiment, it is possible to prevent the outdoor air containing dust from entering the first adsorption element (81) and the second adsorption element (82) while the humidity control apparatus is stopped. For this reason, it can prevent that the 1st adsorption | suction element (81) and the 2nd adsorption | suction element (82) are contaminated with the dust in outdoor air during a stop of a humidity control apparatus, and the 1st adsorption | suction element (81) and 2nd The lifetime of the adsorption element (82) can be extended.

-Modification 2 of Embodiment 1
In the humidity control apparatus of the present embodiment, the operation may be stopped after performing the following operation in advance.

<Fifth Modification>
When the humidification operation is stopped, the humidity control apparatus may be stopped after performing an operation for adsorbing moisture on the adsorption elements (81, 82) in advance. This operation will be described with reference to FIGS.

  First, the operation when adsorbing moisture in outdoor air to the adsorbing elements (81, 82) will be described with reference to FIG. In this case, in the right partition plate (20), the first upper right damper (23), the first lower right damper (24), the second upper right damper (25), and the second lower right damper (26) are opened. The first right damper (21) and the second right damper (22) are closed. In the left partition plate (30), all dampers, that is, the first left damper (31), the second left damper (32), the first upper left damper (33), the first lower left damper (34), and the second upper left damper are provided. The damper (35) and the second lower left damper (36) are closed. The first center damper (61) and the second center damper (62) may be in an open state or a closed state. The compressor (71) of the refrigerant circuit is stopped.

  In this state, only the exhaust fan (45) is driven and the air supply fan (46) is stopped. About half of the outdoor air that has flowed into the lower right channel (66) from the outside air suction port (13) passes through the first lower right damper (24) and the first lower channel (54) in order. It flows into the humidity control side passageway (85) of the adsorption element (81), and the remaining half passes through the second lower right damper (26) and the second lower flow path (56) in order, and passes through the second adsorption element ( 82) into the humidity control side passageway (85). In the first and second adsorption elements (81, 82), moisture in the outdoor air is adsorbed by the adsorbent. The outdoor air deprived of moisture by the first adsorption element (81) sequentially passes through the first upper channel (53) and the first upper right damper (23) and flows into the upper right channel (65). The outdoor air deprived of moisture by the second adsorbing element (82) sequentially passes through the second upper channel (55) and the second upper right damper (25) and flows into the upper right channel (65). And the outdoor air which flowed into the upper right part flow path (65) flows in into the 1st space (41), and is discharged | emitted outside through an exhaust port (14).

  Next, an operation in the case where moisture in room air is adsorbed by the adsorbing elements (81, 82) will be described with reference to FIG. In this case, in the right partition plate (20), the first upper right damper (23) and the second upper right damper (25) are opened, and the first right damper (21), the second right damper (22), and the first lower right damper are opened. The damper (24) and the second lower right damper (26) are closed. In the left partition plate (30), the first lower left damper (34) and the second lower left damper (36) are opened, and the first left damper (31), the second left damper (32), the first upper left damper ( 33) and the second upper left damper (35) are closed. The first center damper (61) and the second center damper (62) may be in an open state or a closed state. The compressor (71) of the refrigerant circuit is stopped.

  In this state, only the exhaust fan (45) is driven and the air supply fan (46) is stopped. About half of the room air that has flowed into the lower left channel (68) from the room air inlet (15) passes through the first lower left damper (34) and the first lower channel (54) in order, and is first adsorbed. It flows into the humidity control side passageway (85) of the element (81), and the remaining half passes through the second lower left damper (36) and the second lower flow path (56) in order, and the second adsorption element (82). Flows into the humidity control side passageway (85). In the first and second adsorption elements (81, 82), moisture in the room air is adsorbed by the adsorbent. The room air deprived of moisture by the first adsorption element (81) sequentially passes through the first upper flow path (53) and the first upper right damper (23) and flows into the upper right flow path (65). The room air deprived of moisture by the second adsorption element (82) sequentially passes through the second upper flow path (55) and the second upper right damper (25) and flows into the upper right flow path (65). The room air that has flowed into the upper right channel (65) flows into the first space (41), and is discharged to the outside through the exhaust port (14).

  The humidity control apparatus of this modification performs the operation of adsorbing moisture in outdoor air or moisture in indoor air on the first and second adsorption elements (81, 82) as described above, and then the right partition plate ( 20) Close all dampers (21, ..., 31, ...) provided on the left partition plate (30) and then stop. During the stop of the humidity control apparatus, the first adsorption element (81) and the second adsorption element (82) are isolated from both the room and the outdoor, and the first adsorption element (81) and the second adsorption element are separated. The element (82) is held in a state where a relatively large amount of moisture is adsorbed. For this reason, when the humidity control device restarts the humidification operation, the air can be humidified using the moisture previously adsorbed to the adsorption element (81, 82) before the stop, and immediately after the start of the humidification operation. Thus, it is possible to reliably humidify the air supplied to the room. As a result, it is possible to shorten the time required from when the humidity control device is started until the room is in a comfortable state.

  Here, when aldehyde, which is an odor component, is contained in the air passing through the adsorption element (81, 82) during operation, there is a possibility that the aldehyde is adsorbed and accumulated on the adsorption element (81, 82). is there. On the other hand, if the operation of adsorbing moisture to the adsorbing element (81, 82) as described above is performed, the aldehyde adsorbed on the adsorbing element (81, 82) replaces the moisture and the adsorbing element (81, 82). Detach from. At this time, the aldehyde desorbed from the adsorption element (81, 82) is discharged to the outside together with the air that has passed through the adsorption element (81, 82). Therefore, according to this modification, aldehyde can be removed from the adsorption element (81, 82) before the operation is stopped, and the aldehyde adsorbed on the adsorption element (81, 82) can be removed indoors after the operation is resumed. The indoor comfort can be secured by preventing the supply to the room.

  In this modification, the adsorption element (81, 82) is kept in a state of being isolated from both the room and the outdoor while the humidity control apparatus is stopped. For this reason, air containing odorous substances such as aldehyde can be prevented from entering the adsorption element (81, 82) while the humidity controller is stopped, and the aldehyde in the air is adsorbed by the adsorption element (81, 82). Can be prevented.

<Sixth Modification>
When the dehumidifying operation or the humidifying operation is stopped, the humidity control apparatus may be stopped after performing an operation for drying the adsorption elements (81, 82) in advance. This operation will be described with reference to FIGS.

  The operation of drying the first adsorption element (81) will be described with reference to FIG. In this case, in the right partition plate (20), the second right damper (22) and the first upper right damper (23) are opened, the first right damper (21), the first lower right damper (24), and the second upper right damper. The damper (25) and the second lower right damper (26) are closed. In the left partition plate (30), all the dampers, that is, the first left damper (31), the second left damper (32), the first upper left damper (33), the first lower left damper (34), the second upper left damper ( 35) and the second lower left damper (36) are closed. In addition, the first central damper (61) is opened and the second central damper (62) is closed. In the refrigerant circuit, a refrigeration cycle is performed, and the regeneration heat exchanger (72) serves as a condenser and the first heat exchanger (73) serves as an evaporator.

  In this state, only the exhaust fan (45) is driven and the air supply fan (46) is stopped. The outdoor air that has flowed into the lower right channel (66) from the outside air inlet (13) in turn flows into the second right damper (22), the second channel (52), and the cooling side passage ( 86) and flows into the central flow path (57). The outdoor air that has flowed into the central flow path (57) is heated while passing through the heat exchanger for regeneration (72), and then sequentially passes through the first central damper (61) and the first lower flow path (54). Pass through and flow into the humidity control side passageway (85) of the first adsorption element (81). The first adsorption element (81) is heated by the introduced outdoor air, and moisture is desorbed from the first adsorption element (81). The outdoor air to which moisture desorbed from the first adsorption element (81) is given passes through the first upper channel (53), the first upper right damper (23), and the upper right channel (65) in this order. It flows into the first space (41) and is discharged out of the room through the exhaust port (14).

  The operation of drying the second adsorption element (82) will be described with reference to FIG. In this case, in the right partition plate (20), the first right damper (21) and the second upper right damper (25) are opened, the second right damper (22), the first upper right damper (23), and the first lower right damper. The damper (24) and the second lower right damper (26) are closed. In the left partition plate (30), all the dampers, that is, the first left damper (31), the second left damper (32), the first upper left damper (33), the first lower left damper (34), the second upper left damper ( 35) and the second lower left damper (36) are closed. The second central damper (62) is opened and the first central damper (61) is closed. In the refrigerant circuit, a refrigeration cycle is performed, and the regeneration heat exchanger (72) serves as a condenser and the first heat exchanger (73) serves as an evaporator.

  In this state, only the exhaust fan (45) is driven and the air supply fan (46) is stopped. The outdoor air that has flowed into the lower right channel (66) from the outside air inlet (13) is in turn supplied to the first right damper (21), the first channel (51), and the cooling side passage ( 86) and flows into the central flow path (57). The outdoor air that has flowed into the central flow path (57) is heated while passing through the regeneration heat exchanger (72), and then sequentially flows through the second central damper (62) and the second lower flow path (56). Pass through and flow into the humidity control side passageway (85) of the second adsorption element (82). The second adsorption element (82) is heated by the introduced outdoor air, and moisture is desorbed from the second adsorption element (82). The outdoor air to which moisture desorbed from the second adsorption element (82) is given passes through the second upper channel (55), the second upper right damper (25), and the upper right channel (65) in this order. It flows into the first space (41) and is discharged out of the room through the exhaust port (14).

  The humidity control apparatus according to this modification performs both the operation of drying the first adsorption element (81) and the operation of drying the second adsorption element (82), and then the right partition plate (20) and the left side. Close all dampers (21, ..., 31, ...) provided on the partition plate (30) and then stop. While the humidity control apparatus is stopped, the first adsorption element (81) and the second adsorption element (82) are kept in a dry state in a state where they are isolated from both the room and the outdoors.

  Here, if the adsorbing element (81, 82) is left in a damp state while the humidity control device is stopped, the adsorbing element (81, 82) is moldy, and the adsorbing element (81, 82) is rapidly deteriorated. There is a problem. On the other hand, according to this modification, since the adsorption element (81, 82) is dried in advance before stopping, the adsorption element (81, 82) can be kept dry even while the humidity control apparatus is stopped. Become. Therefore, according to this modification, it is possible to prevent mold from being generated in the adsorption element (81, 82) while the humidity control apparatus is stopped, and the life of the adsorption element (81, 82) can be extended. .

  Further, when the dehumidifying operation is resumed in the humidity control apparatus of this modification, the air supplied to the room immediately after the dehumidifying operation is resumed by using the adsorption elements (81, 82) kept in a dry state. Can be reliably dehumidified. As a result, it is possible to shorten the time required from when the humidity control device is started until the room is in a comfortable state.

  In addition, when ammonia that is an odor component is contained in the air passing through the adsorption element (81, 82) during operation, the ammonia may be adsorbed and accumulated on the adsorption element (81, 82). . On the other hand, if the operation of drying the adsorption element (81, 82) as described above is performed, ammonia is desorbed from the heated adsorption element (81, 82). The ammonia desorbed from the adsorption element (81, 82) is discharged to the outside together with the air that has passed through the adsorption element (81, 82). Therefore, according to this modification, ammonia can be removed from the adsorption element (81, 82) before the operation is stopped, and the ammonia adsorbed on the adsorption element (81, 82) can be removed indoors after the operation is resumed. The indoor comfort can be secured by preventing the supply to the room.

<Seventh Modification>
The humidity control apparatus of this embodiment may be installed in a state where an exhaust duct is connected to the exhaust port (14) of the casing (10). In such a case, the second air containing moisture desorbed from the adsorption elements (81, 82) flows in the exhaust duct during the dehumidifying operation. For this reason, the air containing a lot of moisture stays in the exhaust duct even after the dehumidification operation is stopped, and there is a problem that condensation of the exhaust duct or generation of dust occurs and the exhaust duct is rapidly deteriorated. .

  Therefore, when the dehumidifying operation is stopped, the humidity control apparatus may be stopped after an operation for drying the inside of the exhaust duct connected to the casing (10) is performed in advance. This operation will be described with reference to FIG. In FIG. 16, the exhaust duct is not shown.

  When performing this operation, in the right partition plate (20), the first upper right damper (23) and the first lower right damper (24) are opened, and the first right damper (21), the second right damper (22), The second upper right damper (25) and the second lower right damper (26) are closed. In the left partition plate (30), all dampers, that is, the first left damper (31), the second left damper (32), the first upper left damper (33), the first lower left damper (34), and the second upper left damper are provided. The damper (35) and the second lower left damper (36) are closed. The first center damper (61) and the second center damper (62) may be in an open state or a closed state. The compressor (71) of the refrigerant circuit is stopped.

  In this state, only the exhaust fan (45) is driven and the air supply fan (46) is stopped. The outdoor air that has flowed into the lower right channel (66) from the outside air inlet (13) is in turn controlled by the first lower damper (24), the first lower channel (54), and the first adsorption element (81). Through the side passage (85) in order, and then sequentially through the first upper channel (53), the first upper right damper (23), and the upper right channel (65) to the first space (41). It flows into the exhaust duct through the exhaust port (14). That is, air having a lower humidity flows in the exhaust duct during this operation than in the dehumidifying operation. And if this state is continued for a while, the inside of the exhaust duct will be in a dry state.

  Here, the operation in which the outdoor air taken into the casing (10) is introduced into the exhaust duct after passing through the first adsorption element (81) has been described. However, the outdoor air taken into the casing (10) The inside of the exhaust duct may be dried by performing an operation of being introduced into the exhaust duct after passing through the two adsorption elements (82).

-Modification 3 of Embodiment 1-
In the humidity control apparatus of the present embodiment, the operation may be started after performing the following operation in advance.

<Eighth Modification>
If the odor component such as ammonia or aldehyde is contained in the air passing through the adsorption element (81, 82) during operation, the odor component may be adsorbed and accumulated on the adsorption element (81, 82). is there. If the odor component is accumulated in the adsorption element (81, 82), the odor component may be detached from the adsorption element (81, 82) and stay in the casing (10) while the humidity control device is stopped. is there. For this reason, when the operation is resumed, the odor component staying in the casing (10) is supplied to the room, which may impair comfort.

  Therefore, when the humidity control apparatus is started, a purge operation for discharging the odor component staying in the casing (10) to the outside may be performed in advance, and then the dehumidifying operation or the humidifying operation may be started. In this purge operation, the state of each damper (21,..., 31,...) And the flow of air in the casing (10) cause the moisture in the outdoor air to flow into the adsorption element (81, 82) in the fifth modification. This is exactly the same as when adsorbing (see FIG. 12).

  That is, the first upper right damper (23), the first lower right damper (24), the second upper right damper (25), and the second lower right damper (26) are opened and the remaining dampers (21, 22,...). Is closed, only the exhaust fan (45) is driven, and the air supply fan (46) remains stopped. A part of the outdoor air taken into the casing (10) from the outside air inlet (13) passes through the first adsorption element (81) and the rest passes through the second adsorption element (82). At that time, the odor component that has been desorbed from the adsorbing element (81 82) and stayed there flows with the outdoor air passing through the adsorbing element 81, and is discharged from the exhaust port 14 to the outside.

<Ninth Modification>
When the humidity control device is started, it takes some time for the temperature of the regeneration heat exchanger (72) to rise sufficiently even if the compressor (71) is started. ) Is sufficiently warmed, the temperature of the second air that has passed through the regeneration heat exchanger (72) does not rise sufficiently. For this reason, for example, when the humidification operation is started in winter, the second air having a relatively low temperature that has passed through the regeneration heat exchanger (72) that has not yet been warmed is supplied to the room, and the room is present. May cause discomfort to the person.

  Therefore, when the humidity control device is started, a preheating operation for increasing the temperature of the regeneration heat exchanger (72) is performed in advance, and then the air supply fan (46) is driven to supply air into the room. May be started.

  In this preheating operation, the dampers (21,..., 31,...) Are held in the same state as when stopped (see FIG. 7). That is, all the dampers (21,..., 31,...) Provided on the right partition plate (20) and the left partition plate (30) are held in the closed state. Further, only the compressor (71) of the refrigerant circuit is started with both the air supply fan (46) and the exhaust fan (45) stopped. In this state, the high-temperature refrigerant discharged from the compressor (71) is supplied to the regeneration heat exchanger (72), and the regeneration heat exchanger (72) is warmed. When a certain amount of time has passed and the temperature of the regenerative heat exchanger (72) has risen sufficiently, the air supply fan (46) and the exhaust fan (45) are driven and the dampers (21,..., 31, ...) is set to a predetermined state, and dehumidifying operation or humidifying operation is started.

  Further, as the preheating operation, the following operation may be performed. That is, while operating the compressor (71), the exhaust fan (45) may be operated to allow outdoor air to flow in the casing (10). In this preheating operation, the state of each damper (21,..., 31,...) And the flow of air in the casing (10) cause the first adsorption element (81) to be dried in the sixth modification (FIG. 14). See).

  That is, the second right damper (22) and the first upper right damper (23) are opened, the remaining dampers (21, 24,...) Are closed, and only the exhaust fan (45) is driven to supply the air supply fan (46). ) Will remain stopped. When the compressor (71) is operated in this state, a refrigeration cycle is performed in the refrigerant circuit, the regeneration heat exchanger (72) becomes a condenser, and the first heat exchanger (73) becomes an evaporator. The outdoor air taken into the casing (10) from the outside air inlet (13) absorbs heat from the refrigerant when passing through the regeneration heat exchanger (72), and then the first heat exchanger (73). When it passes through, it dissipates heat to the refrigerant, and is then discharged outside from the exhaust port (14).

I mean.

  As shown in FIGS. 17 to 19, in the humidity control apparatus of the present embodiment, the adsorption element (165), the sensible heat exchanger (170), the regeneration heat exchanger (166) and the like are housed in the casing (110). ing. This humidity control apparatus is configured to switch between a dehumidifying operation for dehumidifying the taken outdoor air and supplying it to the room, and a humidifying operation for humidifying the taken outdoor air and supplying it to the room.

  The casing (110) is formed in a flat rectangular parallelepiped shape that is long in the front-rear direction and low in height. The inside of the casing (110) is partitioned into three spaces in the front-rear direction. The space of the casing (110) divided into three parts is that the most outdoor space constitutes the outdoor space (120), and the most indoor space constitutes the indoor space (125). This space constitutes the central space (130).

  The outdoor space (120) is divided into left and right. The right half of the outdoor space (120) constitutes an outdoor inlet flow path (121), and the left half of the outdoor space (120) constitutes an outdoor outlet flow path (122). An outdoor air suction port (111) and an exhaust port (114) are opened at an end surface on the outdoor side of the casing (110). The outdoor side inlet flow path (121) communicates with the outside through the outside air inlet (111). The outdoor outlet channel (122) communicates with the outside through an exhaust port (114). The outdoor inlet flow path (121) and the outdoor outdoor flow path (122) constitute an outdoor flow path communicating with the outside.

  The indoor space (125) is partitioned into left and right. The right half of the indoor space (125) constitutes an indoor inlet channel (127), and the left half thereof constitutes an indoor outlet channel (126). An air supply port (112) and an inside air suction port (113) are open on the end surface of the casing (110) on the outdoor side. The indoor outlet channel (126) communicates with the room through the air supply port (112). The indoor side inlet channel (127) is communicated with the room by the indoor air suction port (113). The indoor side outlet channel (126) and the indoor side inlet channel (127) constitute an indoor side channel communicating with the room. Further, an air supply fan (167) is installed inside the indoor outlet channel (126), and an exhaust fan (168) is installed inside the indoor inlet channel (127).

  The central space (130) is partitioned into three spaces in the vertical direction. In FIG. 17, illustration of some of the partitions is omitted. A sensible heat exchanger (170) is accommodated in the lowermost space in the central space (130). On the other hand, the uppermost space and the middle space in the central space (130) are each divided into left and right. In the uppermost space in the central space (130), the right half constitutes the dehumidification side upstream flow path (135), and the left half constitutes the humidification side downstream flow path (138). The right half of the intermediate space in the central space (130) constitutes the dehumidification side downstream flow path (136), and the left half constitutes the humidification side upstream flow path (137).

  The sensible heat exchanger (170) is formed in a flat rectangular parallelepiped shape having a low height. The sensible heat exchanger (170) has a square shape on the upper and lower surfaces. In the sensible heat exchanger (170), a plurality of first air passages (171) and a plurality of second air passages (172) are alternately formed in the height direction. Of the four side surfaces of the sensible heat exchanger (170), the first air passage (171) opens on the two opposite side surfaces, and the second air passage (172) opens on the remaining two side surfaces. ing. The sensible heat exchanger (170) is configured to exchange heat between the air flowing through the first air passage (171) and the air flowing through the second air passage (172).

  The sensible heat exchanger (170) is placed on the bottom plate of the casing (110). The sensible heat exchanger (170) is installed in such a posture that one of the diagonal lines on the upper surface thereof is along the center in the left-right width direction of the casing (110). Further, in the sensible heat exchanger (170), the opening side of the first air passage (171) is located on the front right side and the back left side, and the opening side of the second air passage (172) is on the front left side and the back side. The posture is located on the right side.

  With the sensible heat exchanger (170) installed at the bottom of the central space (130), four substantially triangular spaces are formed on the side of the sensible heat exchanger (170) as viewed from above. The Of these four spaces, the right space on the front side is the first introduction path (131) communicating with the first air passage (171) of the sensible heat exchanger (170), and the left space is the sensible heat exchanger (170). The first lead-out passage (132) communicating with the first air passage (171) of the second introduction passage (133) with the space on the back right side communicating with the second air passage (172) of the sensible heat exchanger (170) The space on the left side in front forms a second lead-out path (134) that communicates with the second air path (172) of the sensible heat exchanger (170).

  The adsorption element (165) is formed in a disk shape as a whole and is driven to rotate around its central axis. The adsorbing element (165) is configured by applying an adsorbent such as zeolite on the surface of a honeycomb-shaped substrate, and a plurality of air passages penetrating in the thickness direction are formed. And this adsorption | suction element (165) comprises the member for adsorption | suction which makes the air which flows through an air path, and adsorbent contact.

  In the central space (130) in the casing (110), the adsorption element (165) is disposed so as to overlap the sensible heat exchanger (170). At that time, the adsorbing element (165) has a posture in which the center position thereof coincides with the center position of the upper surface of the sensible heat exchanger (170), and the dehumidification side upstream flow path (135) and the humidification side downstream flow path (138). It is arranged across both. A circular opening having a diameter substantially the same as the diameter of the adsorption element (165) is formed in the partition between the uppermost portion and the middle portion of the central space (130). And the lower end part of the adsorption | suction element (165) is stuck in this circular opening.

  The regeneration heat exchanger (166) is a so-called cross fin type fin-and-tube heat exchanger, and is formed in a flat plate shape. The regeneration heat exchanger (166) is disposed in the humidification side upstream flow path (137) in a substantially horizontal posture. Hot water is supplied to the heat transfer tubes of the regeneration heat exchanger (166). The regeneration heat exchanger (166) constitutes a heater that heats air with hot water.

  In the partition between the outdoor space (120) and the central space (130) in the casing (110), as an outdoor open / close damper, a first outdoor upper damper (141), a first outdoor lower damper ( 142), a second outdoor side upper damper (143), and a second outdoor side lower damper (144) are provided. The first outdoor upper damper (141) is arranged at the upper right part of the partition, and intermittently connects between the outdoor inlet flow path (121) and the dehumidification side upstream flow path (135).

During the dehumidifying operation or the humidifying operation of the humidity control apparatus, the outdoor air taken into the casing (110) is supplied to the room while the taken indoor air is discharged to the outside. ), The interior and the exterior communicate with each other. For this reason, if the dampers (141,..., 146,...) Are kept in operation when the operation is stopped, the outdoor air enters the room through the casing (110) during the stop. The indoor environment may be worse than necessary.

  Therefore, as shown in FIG. 20, the humidity control apparatus includes all the dampers (146,...) Constituting the indoor open / close damper and all the dampers (141,...) Constituting the outdoor open / close damper. Close when you stop.

In the humidity control apparatus of the present embodiment, all the dampers (141,..., 146,...) Constituting the indoor side and outdoor side open / close dampers are shut off during the stoppage. The closed state is maintained, and the entry of outdoor air into the room is prevented. Therefore, according to the present embodiment, the same effect as that obtained in the first embodiment can be obtained.

  The second operation during the humidifying operation will be described. In the second operation, an adsorption operation for the second adsorption heat exchanger (242) and a regeneration operation for the first adsorption heat exchanger (241) are performed.

  Specifically, during the second operation, as shown in FIG. 25, the first lower right damper (233) and the second upper right damper (232) are opened, and the first upper right damper (231) and the second upper damper (231) The lower right damper (234) is closed. Further, the first upper left damper (235) and the second lower left damper (238) are opened, and the first lower left damper (237) and the second upper left damper (236) are closed.

  In the refrigerant circuit, the first adsorption heat exchanger (241) serves as a condenser, and the second adsorption heat exchanger (242) serves as an evaporator. That is, the high-temperature refrigerant discharged from the compressor (240) is introduced into the heat transfer tube of the first adsorption heat exchanger (241) as a heating heat medium, and the low-temperature refrigerant after being depressurized by the expansion valve is cooled. Is introduced into the heat transfer tube of the second adsorption heat exchanger (242) as a heat transfer medium.

  The first air that has flowed into the lower left flow path (224) from the inside air suction port (213) flows into the lower side of the second adsorption heat exchanger (242) through the second lower left damper (238), and is subjected to the second adsorption. Passes through the heat exchanger (242) from bottom to top. In the second adsorption heat exchanger (242), the moisture in the first air is adsorbed by the adsorbent to dehumidify the first air, and the heat of adsorption generated at that time is absorbed by the refrigerant. The first air deprived of moisture by the second adsorption heat exchanger (242) flows into the upper right channel (221) through the second upper right damper (232) and passes through the exhaust side channel (225). It is discharged outside through the exhaust port (214).

  The second air flowing into the lower right channel (222) from the outside air inlet (211) flows into the lower side of the first adsorption heat exchanger (241) through the first lower right damper (233), and the first air It passes through the adsorption heat exchanger (241) from bottom to top. In the first adsorption heat exchanger (241), moisture is desorbed from the adsorbent heated by the refrigerant, and the desorbed moisture is given to the second air. The second air humidified by the first adsorption heat exchanger (241) flows into the upper left channel (223) through the first upper left damper (235), and is supplied after passing through the air supply side channel (226). It is supplied into the room from the mouth (212).

-Operation when stopping-
During the dehumidifying operation and humidifying operation of the humidity control apparatus, the outdoor air taken into the casing (210) is supplied to the room, while the taken indoor air is discharged to the outside. ), The interior and the exterior communicate with each other. For this reason, if the dampers (231,..., 235,...) Are kept in operation when the operation is stopped, the outdoor air enters the room through the casing (210) during the stop. The indoor environment may be worse than necessary.

  Therefore, as shown in FIG. 26, the humidity control apparatus includes all the dampers (235,...) Constituting the indoor open / close dampers and all the dampers (231,...) Constituting the outdoor open / close dampers. Close when you stop.

  Specifically, the humidity control apparatus is set to a closed state when stopping the first upper left damper (235), the second upper left damper (236), the first lower left damper (237), and the second lower left damper (238). During the stop, these dampers (235,...) Are kept closed. Thereby, the first adsorption heat exchanger (241) and the second adsorption heat exchanger (242) are separated from the upper left channel (223) and the lower left channel (224), which are indoor side channels.

  Furthermore, the humidity control apparatus is set to a closed state when stopping the first upper right damper (231), the second upper right damper (232), the first lower right damper (233), and the second lower right damper (234). During the stop, these dampers (231,...) Are kept closed. Thus, the first adsorption heat exchanger (241) and the second adsorption heat exchanger (242) are separated from the upper right channel (221) and the lower right channel (222), which are outdoor channels.

  As described above, when the humidity control apparatus is stopped, the upper right flow path (221), the lower right flow path (222), the upper left flow path (223), and the lower left flow path (224) are changed in the casing (210). The first adsorption heat exchanger (241) and the second adsorption heat exchanger (242) are isolated from each other. In other words, outdoor air can only enter the upper right channel (221) and lower right channel (222), and indoor air can only enter the upper left channel (223) and lower left channel (224). Is blocked.

-Effect of Embodiment 3-
In the humidity control apparatus of the present embodiment, all the dampers (231,..., 235,...) That constitute the indoor and outdoor open / close dampers are shut off during the stoppage. The closed state is maintained, and the entry of outdoor air into the room is prevented. Therefore, according to the present embodiment, the same effect as that obtained in the first embodiment can be obtained.

-Modification of Embodiment 3-
In the humidity control apparatus of the present embodiment, the operation may be started after performing the following operation in advance.

<Tenth Modification>
When the humidity control device is started, it takes some time for the temperature of the adsorption heat exchanger (241, 242), which becomes a condenser, to rise sufficiently even if the compressor (240) is started. The temperature of the second air that has passed through the adsorption heat exchanger (241,242) is not sufficiently increased until the chamber (241,242) is sufficiently warmed. For this reason, for example, when the humidification operation is started in winter, the second air having a relatively low temperature that has passed through the adsorption heat exchanger (241, 242) that has not yet been heated is supplied to the room, and the person in the room May cause discomfort.

  Therefore, when the humidity control device is started, a preheating operation for increasing the temperature of the adsorption heat exchanger (241, 242) serving as a condenser is performed in advance, and then the air supply fan (246) is driven. You may make it start air supply to a room | chamber interior.

  In this preheating operation, the dampers (231,..., 235,...) Are held in the same state as when stopped (see FIG. 26). That is, all the dampers (231,..., 235,...) Provided on the right partition plate (20) and the left partition plate (30) are held in the closed state. Further, only the compressor (240) of the refrigerant circuit is started with both the air supply fan (246) and the exhaust fan (245) stopped. In this state, the high-temperature refrigerant discharged from the compressor (240) is supplied to the adsorption heat exchanger (241, 242) serving as a condenser, and the adsorption heat exchanger (241, 242) is warmed. When a certain amount of time elapses and the temperature of the adsorption heat exchanger (241,242) rises sufficiently, the air supply fan (246) and the exhaust fan (245) are driven and the dampers (231,..., 235,. ) Is set to a predetermined state, and the dehumidifying operation or the humidifying operation is started.

  As described above, the present invention is useful for a humidity control apparatus that supplies conditioned air to a room.
