Summary of the Invention

Problems to be Solved by the Invention

[0004] The dehumidifying ventilation operation is usually performed during a period of high humidity and warmth when people feel uncomfortable. However, when the indoor space is cooled by the cooling operation during the dehumidifying ventilation operation, the room temperature may drop too much. In this case, when ventilation is performed, high-humidity air enters and the dehumidifying ability of the indoor space by the humidity control device becomes insufficient. Also, in this case, a configuration for performing a reheating dehumidifying operation that can dehumidify the interior while suppressing a drop in room temperature can be considered. However, the mechanism for performing the reheating dehumidifying operation is complex, and the condensation temperature becomes high to generate heat, resulting in a decrease in efficiency.

[0035] The refrigerant circuit (R) mainly comprises a compressor (12), an outdoor heat exchanger (14), an expansion valve (15), a four-way switching valve (16), and an indoor heat exchanger (34).

[0036] The refrigerant circuit (R) performs a first refrigeration cycle and a second refrigeration cycle in response to the switching of the four-way switching valve (16). The first refrigeration cycle is a refrigeration cycle in which the indoor heat exchanger (34) functions as an evaporator and the outdoor heat exchanger (14) functions as a heat radiator. The second refrigeration cycle is a refrigeration cycle in which the indoor heat exchanger (34) functions as a heat radiator and the outdoor heat exchanger (14) functions as an evaporator.

Inside the outdoor casing (11), an outdoor air passage (11c) is formed, extending from the outdoor intake (11a) to the outdoor air outlet (11b).

[0039] The compressor (12) draws in low-pressure gaseous refrigerant and compresses it. The compressor (12) is driven by the first motor (M1). The compressor (12) is a variable-capacity compressor in which power is supplied to the first motor (M1) from an inverter circuit. The compressor (12) is configured so that its operating capacity can be changed by adjusting the operating frequency (rotational speed) of the first motor (M1). The compressor (12) is a so-called high-pressure dome type, in which its interior is filled with high-pressure refrigerant.

The outdoor heat exchanger (14) exchanges heat between the refrigerant flowing inside it and the outdoor air transported by the outdoor fan (13).

[0042] The expansion valve (15) reduces the pressure of the refrigerant. The expansion valve (15) is an electrically operated expansion valve with an adjustable opening. The pressure reduction mechanism may be a temperature-sensitive expansion valve, an expander, a capillary tube, etc. The expansion valve (15) only needs to be connected to the liquid line of the refrigerant circuit (R) and may be installed in the indoor unit (30) of the air conditioner.

The humidity control rotor (22) carries a predetermined functional material as an adsorbent that improves infrared absorption. The humidity control rotor (22) holds adsorbents such as high-molecular polymers, silica gel, zeolite, and alumina. The adsorbent has the property of adsorbing moisture from the air. The desiccant has the property of desorbing the adsorbed moisture when heated. The humidity control rotor (22) is placed in a predetermined position so that infrared rays generated by the heater (25) reach it, and is heated by the heater (25).

[0049] The humidity control rotor (22) rotates under the drive of the third motor (M3). The humidity control rotor (22) has a humidity control region (22A) located in the first passage (27). In the humidity control region (22A), a regeneration operation is performed in which moisture adsorbed on the adsorbent is released into the air, and an adsorption operation is performed in which moisture from the air is adsorbed onto the adsorbent.

[0050] The first fan (26) is positioned downstream of the humidity control region (22A) in the first passage (27). The first fan (26) transports outdoor air so that it passes through the humidity control region (22A) of the humidity control rotor (22). The first fan (26) is rotated by the drive of the fourth motor (M4). The first fan (26) is configured so that the airflow can be switched between multiple stages by adjusting the rotation speed of the fourth motor (M4).

The flow path switching mechanism may consist of a flow path switching valve or a shut-off valve. The first switching damper (24) switches between a first state (shown by the solid line in Figure 2) and a second state (shown by the dashed line in Figure 2). In the first state, the first switching damper (24) connects the first passage (27) to the inside of the hose (2) and blocks the first passage (27) to the discharge passage (28). In the second state, the first switching damper (24) blocks the first passage (27) to the inside of the hose (2) and connects the first passage (27) to the discharge passage (28).

The indoor casing (31) has an indoor intake port (31a) and an indoor outlet port (31b). The indoor intake port (31a) is located on the upper side of the indoor casing (31). The indoor intake port (31a) is an opening for drawing in indoor air. The indoor outlet port (31b) is located on the lower side of the indoor casing (31). The indoor outlet port (31b) is an opening for blowing out air after heat exchange or air for humidity control. Inside the indoor casing (31), there is an indoor air passage (31c) that runs from the indoor intake port (31a) to the indoor outlet port (31b).

The flap (37) is formed in the shape of a long plate that extends along the longitudinal direction of the indoor air outlet (31b). The flap (37) rotates when driven by a motor. As the flap (37) rotates, it opens and closes the indoor air outlet (31b).

[0061] The flap (37) is configured to allow for stepwise changes in its inclination angle. The flap (37) in this example can be adjusted to six positions. These six positions include a closed position and five open positions. The five open positions include the approximately horizontal air outlet position shown in Figure 3. In the closed position, the flap (37) substantially closes the indoor air outlet (31b). A gap may be formed between the flap (37) in the closed position and the indoor air outlet (31b).

[0076] During heating operation, the control unit (C) adjusts the target condensation temperature of the indoor heat exchanger (34) so ​​that the indoor temperature detected by the indoor air temperature sensor (53) converges to the set temperature. The control unit (C) controls the rotation speed of the compressor (12) so that the condensation temperature of the refrigerant in the indoor heat exchanger (34) converges to the target condensation temperature. During heating operation, the air transported by the indoor fan (32) is heated as it passes through the indoor heat exchanger (34). The air heated in the indoor heat exchanger (34) is supplied to the indoor space (I) from the indoor air outlet (31b) of the indoor air conditioning unit (30).

[0077] (3-3) Intake operation Supply air operation is the operation of supplying outdoor air to the indoor unit. In supply air operation, outdoor air is sent to the indoor unit (30) through the hose (2), as shown by the solid arrow in Figure 2. In supply air operation, the control unit (C) stops the heater (25), the humidity control rotor (22), and the second fan (23), and operates the first fan (26). The control unit (C) sets the first switching damper (24) to the first state. In supply air operation, the outdoor air transported by the first fan (26) is sent to the indoor unit (30) through the hose (2) and supplied to the indoor space (I) from the indoor air outlet (31b) of the indoor unit (30). Note that supply air operation may be performed simultaneously with cooling or heating operation.

[0078] (3-4) Dehumidification operation In dehumidification operation, the dehumidified air from the humidity control unit (20) is supplied to the room. In this embodiment, the dehumidified air is supplied to the room intermittently. The humidity control unit (20) performs a first operation, a second operation, and a post-regeneration operation. The first operation is to adsorb moisture from the air onto the humidity control rotor (22) and to supply the dehumidified air from the humidity control rotor (22) to the room. The second operation is to regenerate the humidity control rotor (22) and to discharge the air used for regeneration to the outside. The post-regeneration operation will be explained later.

[0079] Specifically, in the first operation, the control unit (C) operates the first fan (26), stops the heater (25), and sets the first switching damper (24) to the first state. The first fan (26) carries The air being supplied flows through the first passage (27) and passes through the humidity control region (22A) of the humidity control rotor (22). In the humidity control region (22A), moisture in the air is adsorbed by the adsorbent. The air dehumidified in the humidity control region (22A) is sent through the hose (2) to the air conditioning indoor unit (30) and supplied to the indoor space (I) from the indoor outlet (31b) of the air conditioning indoor unit (30).

[0080] Preferably, the execution time of the first operation is the time it takes for the portion located in the first passage (27) at the start of the first operation (humidity control region (22A)) to complete at least one rotation as the humidity control rotor (22) rotates. This allows moisture to be adsorbed by the adsorbent around the entire circumference of the humidity control rotor (22) in a single first operation.

[0081] The second operation (regeneration process of the rotor (22)) involves the control unit (C) operating the first fan (26) and heater (25), and setting the first switching damper (24) to the second state. The air transported by the first fan (26) flows through the first passage (27), is heated by the heater (25), and then flows through the humidity control region (22A) of the humidity control rotor (22). In the humidity control region (22A), the adsorbent is regenerated. Specifically, the moisture adsorbed on the adsorbent is detached and released into the air. The air used for the regeneration of the humidity control rotor (22) flows from the first passage (27) through the discharge passage (28) and is discharged outside, as shown by the dashed arrow in Figure 2.

[0082] Preferably, the execution time of the second operation is the time it takes for the portion located in the first passage (27) at the start of the second operation (humidity control region (22A)) to complete at least one rotation as the humidity control rotor (22) rotates. This allows the adsorbent around the entire circumference of the humidity control rotor (22) to be regenerated in a single second operation. In this embodiment, the entire circumference of the humidity control rotor (22) is regenerated in a batch manner.

[0083] (3-5) Humidification operation In humidification operation, the humidification unit (20) supplies humidified air to the room. In this embodiment, humidified air is supplied to the room intermittently. The humidification unit (20) repeatedly performs the third and fourth operations alternately. The third operation involves adsorbing moisture from the air onto the humidification rotor (22) and discharging the air that has passed through the humidification rotor (22) to the outside. The fourth operation involves regenerating the humidification rotor (22) and supplying the air to the room with moisture added from the humidification rotor (22).

[0084] Specifically, in the third operation, the control unit (C) operates the first fan (26), stops the heater (25), and sets the first switching damper (24) to the second state. The air transported by the first fan (26) flows through the first passage (27) and passes through the humidity control region (22A) of the humidity control rotor (22). In the humidity control region (22A), moisture in the air is adsorbed onto the adsorbent. The air with moisture added to the adsorbent in the humidity control region (22A) flows from the first passage (27) through the discharge passage (28) and is discharged outside, as shown by the dashed arrow in Figure 2.

[0085] Preferably, the execution time of the third operation is the time it takes for the portion located in the first passage (27) at the start of the third operation (humidity control region (22A)) to complete at least one rotation as the humidity control rotor (22) rotates. This allows moisture to be adsorbed by the adsorbent around the entire circumference of the humidity control rotor (22) in a single third operation.

[0086] In the fourth operation, the control unit (C) operates the first fan (26) and heater (25), and sets the first switching damper (24) to the first state. The air transported by the first fan (26) flows through the first passage (27), is heated by the heater (25), and then flows through the humidity control region (22A) of the humidity control rotor (22). In the humidity control region (22A), the adsorbent is regenerated. Specifically, the moisture adsorbed by the adsorbent is detached and released into the air. The air containing the moisture detached from the humidity control rotor (22) is sent through the hose (2) to the indoor unit (30) and supplied to the indoor space (I) from the indoor outlet (31b) of the indoor unit (30).

[0087] Preferably, the execution time of the fourth operation is the time it takes for the portion located in the first passage (27) at the start of the fourth operation (humidity control region (22A)) to complete at least one rotation as the humidity control rotor (22) rotates. This allows moisture to be released into the air from the adsorbent around the entire circumference of the humidity control rotor (22) in a single fourth operation.

[0088] (3-6) Dehumidifying Cooling Operation In dehumidifying cooling operation, the cooling operation and dehumidifying operation described above are performed simultaneously. Specifically, the air is dehumidified by the humidity control unit (20) and cooled by the indoor heat exchanger (34), which functions as an evaporator.

[0089] (3-7) Humidifying heating operation In humidified heating operation, the heating operation and humidification operation described above are performed simultaneously. Specifically, the air is humidified by the humidity control unit (20) and heated by the indoor heat exchanger (34), which functions as a radiator.

[0090] (4) Dehumidification and ventilation operation During dehumidification and ventilation operation, the control unit (C) executes the processes shown in steps S10 to S30 in Figure 5. Dehumidification and ventilation operation is a process that ventilates and dehumidifies the indoor space (I).

[0091] As shown in Figures 2, 4, and 5, in step S10, the control unit (C) performs the first operation of dehumidification. In the first operation, the outdoor air transported by the first fan (26) is dehumidified by the dehumidification rotor (22) and then supplied to the room. The dehumidification rotor (22) dehumidifies the outdoor air by adsorbing moisture contained in the outdoor air.

[0092] In step S10, the control unit (C) may perform dehumidifying cooling operation by simultaneously performing cooling operation when performing the first operation.

[0093] In step S20, the control unit (C) performs a second operation after the first operation of the dehumidification operation is completed. In the second operation, the moisture adsorbed on the humidity control rotor (22) is heated by the heater (25) and transported by the first fan (26) and detached from the humidity control rotor (22). Then, together with the heated air, it flows from the first passage (27) to the discharge passage (28) as shown by the dashed arrow in Figure 2 and is discharged to the outside. In the second operation, the temperature of the humidity control rotor (22) rises as heated air is supplied to the humidity control rotor (22), and the temperature of the humidity control rotor (22) becomes higher than the temperature of the outside air.

[0094] In step S30, the control unit (C) performs a post-regeneration operation after the second operation is completed. Post-regeneration operation refers to performing the first operation after the completion of the second operation of the dehumidification operation, while the humidity control rotor (22) is not yet cooled (the temperature of the humidity control rotor (22) is higher than the temperature of the outdoor air). In this embodiment, the control unit (C) performs a post-regeneration operation immediately after the second operation is completed.

[0095] During the post-regeneration operation, the heater (25) is stopped and the humidity control rotor (22) is not heated, yet residual heat remains in the humidity control rotor (22) due to heating by the heater (25) during the second operation of step S20. As a result, during the post-regeneration operation, the temperature of the humidity control rotor (22) is higher than the temperature of the outside air.

[0096] During regeneration operation, the outdoor air transported by the first fan (26) passes through the dehumidifying rotor (22) to become treated air. At this time, moisture is adsorbed by the dehumidifying rotor (22) and the treated air is heated by the residual heat contained in the dehumidifying rotor (22). The temperature of the treated air is higher than the temperature of the outdoor air. The humidity of the treated air is lower than the humidity of the outdoor air. The treated air is sent by the first fan (26) through the hose (2) to the indoor air conditioning unit (30), and supplied to the indoor space (I) from the indoor air outlet (31b) of the indoor air conditioning unit (30). The supply of treated air to the indoor space (I) ventilates the indoor space (I).

[0097] The temperature of the processed air is determined according to the temperature of the rotor (22). The higher the temperature of the rotor (22), the higher the temperature of the processed air.

[0098] Furthermore, once the post-regeneration operation in step S30 is completed, the process may proceed to step S20 and the second operation (regeneration process of the rotor (22)) may be performed.

[0099] (5) Effects As described above, the air conditioning system (1) includes a humidity control unit (20) having a humidity control rotor (22) that adsorbs moisture from the air, and a blower unit (26) that sends treated air, generated by adsorbing moisture contained in the outdoor air by the humidity control rotor (22), to the indoor space (I). The outdoor air is heated by the heat accumulated in the humidity control rotor (22) to become treated air. The temperature of the treated air is higher than the temperature of the indoor air (the temperature of the air present in the indoor space (I) immediately before the treated air is supplied). As a result, when the first operation of dehumidification is performed in step S10, if the temperature of the indoor space (I) (room temperature) drops too low when the air in the indoor space (I) is cooled by cooling operation to lower the humidity of the indoor space (I), in step S30, a regeneration operation is performed to generate treated air heated by the residual heat of the humidity control rotor (22), and this treated air can be supplied to the indoor space (I) where the temperature has dropped too low. According to this, treated air with a higher temperature than the indoor or outdoor air can be supplied to the indoor space (I), thus preventing the temperature of the indoor space (I) from dropping too low. As a result, dehumidification and ventilation can be performed effectively.

[0100] Since the treated air has had moisture adsorbed by the humidity control rotor (22) during the post-regeneration operation, even when supplied to the indoor space (I), it can suppress an increase in the humidity of the indoor space (I). As a result, the state in which the humidity of the indoor space (I) is reduced by the first operation of the dehumidification operation in step S10 can be effectively maintained even when the post-regeneration operation is being performed in step S30. Consequently, dehumidification ventilation operation can be performed effectively.

[0101] Since the regeneration operation in step S30 is performed while the humidity control rotor (22) is still warm after the second operation in step S20 is completed, the time between the completion of the second operation and the start of the regeneration operation can be shortened, allowing for smooth dehumidification and ventilation operation.

[0102] As time elapses during the post-regeneration operation in step S30, the humidity control rotor (22) is continuously exposed to outside air. As a result, the outside air continuously removes heat from the humidity control rotor (22), causing it to cool down. Consequently, the humidity control rotor (22) improves its ability to adsorb moisture from the outside air. This reduces the humidity of the treated air generated by the humidity control rotor (22), allowing low-humidity treated air to be supplied to the indoor space (I), thus effectively dehumidifying the indoor space (I).

[0103] During post-regeneration operation, by supplying treated air with a higher temperature than the indoor or outdoor air to the indoor space (I), the cooling load is intentionally increased, thereby increasing the cooling capacity of the air conditioning unit (1) and promoting dehumidification of the indoor space (I).

[0104] If, for example, after the regeneration operation in step S20, air is prevented from passing through the humidity control rotor (22), and the system is configured to wait for the humidity control rotor (22) to cool naturally until it reaches a temperature similar to the outdoor air temperature before supplying outdoor air to the indoor space (I) via the humidity control rotor (22), then a waiting time for the humidity control rotor (22) to cool naturally will occur, reducing the processing capacity (amount of moisture adsorbed) of the humidity control rotor (22) per unit time, and thus reducing the dehumidification efficiency of the indoor space (I). In addition, during the waiting time for the humidity control rotor (22) to cool naturally (the time when the humidity control rotor (22) is not performing its moisture adsorption function), high-humidity outdoor air may enter the indoor space (I) through gaps, potentially increasing the humidity of the indoor space (I). In contrast, as in this embodiment, after the regeneration operation in step S20, the post-regeneration operation in step S30 is started while the humidity control rotor (22) is still warm (the temperature of the humidity control rotor (22) has not yet dropped to the temperature of the outdoor air), and processed air having a higher temperature than the indoor air is supplied to the indoor space (I). This configuration suppresses the occurrence of a period after the regeneration operation in step S20 in which the humidity control rotor (22) does not perform its moisture adsorption function. As a result, according to this embodiment, a decrease in the processing capacity per unit time of the humidity control rotor (22) can be suppressed, and furthermore, an increase in humidity in the indoor space (I) after the regeneration operation in step S20 can be suppressed.

[0105] <Other Embodiments> (A) The air conditioning unit (1) may be equipped with a measuring unit for measuring the temperature of the rotor (22). In this case, as shown in Figure 5, after the completion of the second operation (see step S20), in step S30, the control unit (C) may, if the temperature of the rotor (22) measured by the measuring unit is higher than a predetermined temperature, not perform the operation of sending treated air to the indoor space (I) by the first fan (26) (post-regeneration operation), and if the temperature of the rotor (22) measured by the measuring unit is below the predetermined temperature, perform the operation of sending treated air to the indoor space (I) by the first fan (26) (post-regeneration operation). The predetermined temperature is determined using the indoor environment and the indoor environment target value, and is higher than the temperature of the outdoor air. The measuring unit includes, for example, a temperature sensor. The measuring unit may directly measure the temperature of the rotor (22), or it may measure the temperature of a component located close to the rotor (22) (for example, a component supporting the rotor (22)), or the ambient temperature around the rotor (22) as the temperature of the rotor (22). This prevents the treated air supplied to the indoor space (I) by the regeneration operation in step S30 from becoming too hot.

[0106] (B) The control unit (C) may perform the process of supplying treated air to the indoor space (I) (post-regeneration operation in step S30) after a predetermined time has elapsed or within a predetermined time after the process of accumulating heat in the rotor (22) (second operation in step S20) has been completed. This allows the temperature of the rotor (22) to be adjusted in accordance with the change in the temperature of the rotor (22) as time passes after the process of accumulating heat in the rotor (22) has been completed, as the temperature of the rotor (22) decreases due to natural cooling. For example, in order to supply treated air to the indoor space (I) before the temperature of the rotor (22) falls below 10 degrees Celsius relative to the ambient temperature, the control unit (C) performs the process of supplying treated air to the indoor space (I) within 10 minutes after the process of accumulating heat in the rotor (22) has been completed.

[0107] (C) The rotation speed of the rotor (22) may differ between humidification and dehumidification. The rotation speed of the rotor (22) may be faster during dehumidification than during humidification. This is because the outdoor temperature is higher during dehumidification than during humidification, resulting in a smaller temperature swing of the adsorbent and a smaller amount of water handled per unit volume. Therefore, it is necessary to rotate the rotor (22) faster to increase its capacity. As a result, dehumidification can be performed effectively.

[0108] (D) In ​​another embodiment, when the outdoor air is heated by the residual heat of the humidity control rotor (22) in step S30 to generate processed air, if the amount of heating of the outdoor air by the residual heat of the humidity control rotor (22) is insufficient, the heater (25) may be operated to the extent that the moisture adsorption capacity of the adsorbent of the humidity control rotor (22) is not lost (heating of the humidity control rotor (22) by the heater (25) may be performed).

[0109] (E)(E-1) Basic configuration The modified air conditioning system (1) shown in Figure 6 continuously supplies humidified air to the room via a humidity control unit (20). In addition, the air conditioning system (1) intermittently supplies dehumidified air to the room via the humidity control unit (20). The differences from the embodiment described above will be explained below. For convenience, the indoor air conditioning unit (30) and the outdoor air conditioning unit (10) are not shown in Figure 6.

[0110] The modified air conditioning unit (1) has an exhaust passage (28) and a first switching damper (24), similar to the embodiment. The outdoor casing (11) of the modified 3 has a humidity control intake port (21a), a connection port (21b), a humidity absorption side intake port (61a), and a humidity absorption side exhaust port (61b), similar to the embodiment. A first passage (27) is formed from the humidity control intake port (21a) to the connection port (21b), and a second passage (62) is formed from the humidity absorption side intake port (61a) to the humidity absorption side exhaust port (61b).

[0111] In the first passage (27), the heater (25), the humidity control region (22A) of the humidity control rotor (22), and the first fan (26) are arranged in order from the upstream side to the downstream side of the airflow. In the second passage (62), the adsorption region (22C) of the humidity control rotor (22) and the second fan (23) are arranged in order from the upstream side to the downstream side of the airflow.

[0112] (E-2) Dehumidification operation In the dehumidification operation of the modified air conditioning system (1), dehumidified air is intermittently supplied to the room. The humidity control unit (20) performs a first operation, a second operation, and a post-regeneration operation, similar to the embodiment shown in Figure 5. Specifically, in the first operation, the control unit (C) operates the first fan (26), stops the second fan (23), stops the heater (25), and sets the first switching damper (24) to the first state. The air transported by the first fan (26) flows through the first passage (27) and passes through the humidity control region (22A) of the humidity control rotor (22). In the humidity control region (22A), moisture in the air is adsorbed by the adsorbent. The air dehumidified in the humidity control region (22A) is sent through the hose (2) to the indoor air conditioning unit (30) and supplied to the indoor space (I) from the indoor air outlet (31b) of the indoor air conditioning unit (30).

[0113] In the second operation, the control unit (C) operates the first fan (26) and heater (25), stops the second fan (23), and sets the first switching damper (24) to the second state. The air transported by the first fan (26) flows through the first passage (27), is heated by the heater (25), and then flows through the humidity control region (22A) of the humidity control rotor (22). In the humidity control region (22A), the adsorbent is regenerated. Specifically, the moisture adsorbed on the adsorbent is detached and released into the air. The air used to regenerate the humidity control rotor (22) flows from the first passage (27) through the discharge passage (28) and is discharged outside, as shown by the dashed arrow in Figure 6.

[0114] In the post-regeneration operation, the first operation is performed after the completion of the second operation while the humidity control rotor (22) is still warm (while residual heat remains in the humidity control rotor (22)). Performing the post-regeneration operation produces the same effects as the embodiment described above.

[0115] (E-3) Dehumidifying Cooling Operation The dehumidifying cooling operation is performed simultaneously with the cooling operation of the above-described embodiment and the dehumidifying operation of the above-described modified example. Specifically, the air is dehumidified by the humidity control unit (20) and cooled by the indoor heat exchanger (34) which functions as an evaporator.

[0116] (E-4) Humidification operation In the humidification operation of the modified air conditioning system (1), the control unit (C) operates the first fan (26) and the second fan (23), drives the humidity control rotor (22) to rotate, and turns on the heater (25). The control unit (C) sets the first switching damper (24) to the first state.

[0117] The outdoor air flowing through the second passage (62) flows through the adsorption region (22C) of the humidity control rotor (22). In the adsorption region (22C), moisture in the air is adsorbed by the adsorbent. The air that has been treated with moisture by the humidity control rotor (22) is discharged to the outside through the second passage (62).

[0118] At the same time, the outdoor air flowing through the first passage (27) is heated by the heater (25) and then flows through the humidity control region (22A) of the humidity control rotor (22). In the humidity control region (22A), moisture released from the adsorbent is released into the air. The air humidified by the humidity control rotor (22) is sent through the hose (2) to the indoor air conditioning unit (30) and supplied to the indoor space (I) from the indoor air outlet (31b) of the indoor air conditioning unit (30).

[0119] (E-5) Humidifying heating operation The humidifying heating operation is performed simultaneously with the heating operation of the embodiment described above and the humidifying operation of the modified example described above. Specifically, the air is humidified by the humidity control unit (20) and heated by the indoor heat exchanger (34), which functions as a radiator.

Furthermore, elements of the above embodiments, modifications, and other embodiments may be combined or substituted as appropriate.
