FIG. 12 shows the flow of air when the humidity controller performs a dehumidifying operation. In the dehumidifying operation, in the moisture absorption passage, the first air suction port switching damper 106 opens to the indoor side, and the first air outlet switching damper 107 opens to the indoor side. In the regeneration passage, the second air outlet switching damper 117 opens to the outside, and the second air inlet switching damper 116 opens to the outside.

When the dehumidifying operation is performed in the regeneration passage and the moisture absorption passage of the above-described path, the humidity controller takes in the indoor air from the first indoor air suction port 102 by the moisture absorption fan 110,
The rotary moisture absorption rotor 101 adsorbs moisture in the air taken in from the room. Then, the air dried by losing moisture is returned from the first indoor air outlet 104 to the room.

And the highly humidified air that has received the moisture is discharged from the second outdoor air outlet 115 to the outside. The flow of the regeneration air is indicated by an arrow 122.

FIG. 13 is a diagram showing the flow of air when the humidifier performs a humidifying operation. In the humidification operation, the first air suction port switching damper 106 opens to the outside in the moisture absorption passage, and the first air outlet switching damper 107
Opens to the outdoor side. In the regeneration passage, the second air outlet switching damper 117 opens to the indoor side, and the second air inlet switching damper 116 opens to the indoor side.

When the humidifying operation is performed in the regeneration passage and the moisture absorption passage of the above path, the humidity controller takes in the outdoor air from the outdoor air suction port 103 by the moisture absorption fan 110, and rotates the moisture from the air taken in from the outside. Hygroscopic rotor 10
1 is adsorbed. Then, the air dried by losing moisture is discharged from the first outdoor air outlet 105 to the outside. The flow of the above-mentioned moisture-absorbing air is indicated by an arrow 121. On the other hand, playback fan 1

01 is released from the water and regenerated, and the air which has received the water and has become highly humid is returned from the second indoor air outlet 114 to the room. The flow of the regeneration air is indicated by an arrow 122.

In a humidity controller capable of performing the above-described dehumidification / humidification / ventilation operation, the operation may be performed using both dehumidification and ventilation. At this time, the second air suction port switching damper 116 is opened at a predetermined ratio from the connection state of the passage during the dehumidifying operation of the humidity controller shown in FIG. 12, and the second indoor air suction port is opened by the regeneration fan 120.

That is, moisture is removed from the rotary moisture absorbing rotor 101 in the regeneration passage and indoor air is ventilated.

[0010]

However, the above-mentioned conventional humidity controller is required to operate the above-mentioned dehumidifier and ventilation together.
When giving priority to ventilation, it is necessary to suck a large amount of room air from the second room air suction port 112 in the regeneration passage,
In that case, the amount of air passing through the rotary moisture absorbing rotor 101 increases, and the speed also increases. Therefore, the air stays in the rotary moisture absorbing rotor 101 for a short time,
Since the efficiency with which the heat from the regeneration heater 113 is transmitted is reduced, the amount of moisture released from the rotary moisture absorbing rotor 101 is reduced, and the dehumidifying ability is reduced.

Conversely, if priority is given to dehumidification, it is necessary to transfer the heat of the regeneration heater 113 efficiently in the regeneration passage while keeping the amount of air passing through the rotary moisture absorption rotor 101 constant. In some cases, the amount of indoor air sucked from the mouth 112 is less than the amount of air necessary for performing indoor ventilation.

That is, when the dehumidifying operation and the humidifying operation are performed in combination, one of the functions is deteriorated, and there is a problem that the operation cannot be performed while satisfying both the dehumidifying and the humidifying functions.

In view of the above problems, an object of the present invention is to provide a humidity controller that can sufficiently exhibit both functions when both dehumidification and humidification are operated.

It is characterized by comprising means for increasing the reproduction fan and the reproduction heater.

According to the humidity controller of the present invention, when air for regeneration and ventilation of moisture is allowed to pass through the rotary moisture absorption rotor, the regenerated air passing through the rotary moisture absorption rotor is more effective than the operation of only dehumidification. The amount and the heating amount of the regeneration heater are increased. Then, even if the residence time of the regeneration air in the rotary moisture absorption rotor is reduced, a sufficient amount of moisture can be released from the rotary moisture absorption rotor because the temperature of the regeneration air is high. Therefore, it is possible to effectively perform both dehumidification and ventilation.

According to the humidity controller of the above embodiment, since the detour which bypasses the rotary moisture absorbing rotor is provided, the rotary moisture absorbing rotor passes the air for both the regeneration of moisture and the ventilation. There is no need to make it. Then, the speed of the regenerated air, which regenerates and separates the moisture and passes through the rotary moisture absorption rotor, becomes slow, and the heat of the regeneration heater can be transmitted efficiently, so that the moisture is sufficiently regenerated from the rotary moisture absorption rotor. And can be separated. Further, the ventilation air can be quickly discharged through the bypass. Therefore, the dehumidifying performance and the ventilation performance of the humidity controller are improved, and both the dehumidification and the ventilation can be effectively performed.

The humidity controller of one embodiment is characterized in that the branch portion of the bypass is provided on the upstream side of the rotary moisture absorbing rotor.

According to the humidity controller of the above embodiment, the branch to the detour which bypasses the rotary moisture absorbing rotor is provided on the upstream side of the rotary moisture absorbing rotor. Only air for regeneration can be passed. Then, a sufficient amount of heat for the regeneration air to regenerate moisture in the rotary moisture absorbing rotor and to separate the moisture can be transmitted to the rotary moisture absorbing rotor. Therefore, the dehumidifying performance of the humidity controller is improved, and both ventilation and dehumidification can be effectively performed.

The position of the passage switching damper 20 when the combined operation of dehumidification and ventilation is performed is the same as that in the case of the dehumidification operation by the humidity controller of the first embodiment. In the block diagram of FIG. 9, when the dehumidification / ventilation operation switch 42 is turned on, a drive command is transmitted from the control unit 39 of the microcomputer 38 to the damper drive circuit 41, and the signal of the damper drive circuit 41 causes the damper drive motor 31 to switch the path.

The opening degree, the air volume of the reproduction fan 15 and the output of the reproduction heater 16 are determined by the control unit 39 of the microcomputer 38. Based on these appropriately determined values, the stepping motor drive circuit 55, the regeneration fan drive circuit 45, and the regeneration heater drive circuit 46 are each provided with a branch damper 53,
The reproducing fan 15 and the reproducing heater 16 are appropriately driven. Further, the temperature detected by the regeneration temperature detection sensor 56 provided upstream of the rotary moisture absorption rotor 1 also corresponds to
The regenerating fan 15 and the regenerating heater 16 are controlled so that the air temperature immediately before crossing the rotary moisture absorbing rotor 1 becomes constant.

By the above control, the humidity controller of this embodiment appropriately controls the amount of air bypassing the regeneration heater 16 and the rotary dehumidifying rotor 1 and the amount of air passing through the rotary dehumidifying rotor 1. By doing so, combined operation of dehumidification and ventilation can be performed in a well-balanced manner. Therefore, this humidity controller can exhibit sufficient dehumidifying ability and can perform ventilation of an air amount suitable for the size of the room.

Further, in the humidity control apparatus of this embodiment, the bypass 50 is connected to the regeneration passage 3 downstream of the regeneration section of the rotary moisture absorption rotor 1.
At the position penetrating the wall of the room immediately before reaching the outdoor air outlet 19, the cross-sectional area of the passage is large, but since there is only one passage connected to the outside, Installation work is easy.

According to the humidity controller of the present invention, the amount of regeneration air passing through the rotary moisture absorption rotor and the amount of heating of the regeneration heater are increased when the dehumidification and ventilation are operated in combination, as compared with the case of the dehumidification operation. Since the air for ventilation in addition to the regeneration air passes through the rotary moisture absorbing rotor, even if the residence time of the air in the rotary moisture absorbing rotor is reduced,
Since the temperature of the air passing through the rotary moisture absorbing rotor is high, moisture can be sufficiently regenerated from the rotary moisture absorbing rotor and separated therefrom, and both dehumidification and ventilation can be performed effectively.

Since the humidity controller of the present invention is provided with a means for adjusting the amount of regenerated air from the room when the dehumidification and the ventilation are operated in combination, the rotary moisture absorption rotor is capable of removing and regenerating moisture. Therefore, both the dehumidification and the ventilation can be effectively performed.

In the humidity control apparatus according to the first embodiment, since a detour is provided to bypass the rotary moisture absorbing rotor, it is not necessary to allow the rotary moisture absorbing rotor to pass both regeneration air and ventilation air. Since the speed of the air passing through the rotary moisture absorbing rotor is moderated, the residence time of the regenerated air in the rotary moisture absorbing rotor is extended, and the moisture can be sufficiently regenerated and separated from the rotary moisture absorbing rotor. Since the dehumidifying performance of the humidity controller is improved and the ventilation can be quickly performed by the detour, both the dehumidification and the ventilation can be effectively performed.

In the humidity controller of one embodiment, since the branch of the bypass is provided on the upstream side of the rotary moisture absorbing rotor, only the regenerated air of moisture can pass through the rotary moisture absorbing rotor. Since the regeneration air passes through the rotary moisture absorption rotor at a speed sufficient to regenerate and separate the moisture from the rotary moisture absorption rotor, the dehumidification performance of the humidity controller is improved, and both the dehumidification and ventilation are effective. Can be done

In the humidity control apparatus according to the first embodiment, the bypass for bypassing the rotary-type moisture absorbing rotor directly communicates with the outside, so that the air for ventilation of the room is immediately discharged to the outside, and the ventilation and dehumidification are performed. And can be performed effectively.

The humidity controller of one embodiment detects the temperature of the air passing through the rotary moisture absorbing rotor on the upstream side of the rotary moisture absorbing rotor, and responds to this temperature to the amount of regenerated air from the room. , The amount of regeneration air optimal for the regeneration and desorption performance of moisture of the rotary moisture absorption rotor can be sent in response to changes in indoor conditions, and dehumidification and ventilation can be performed effectively.
