As shown in FIG. 1, the humidity control apparatus 1 includes a moisture absorbing / desorbing member 3, a heating means 4 for regeneration, a laminated sensible heat exchanger 5
And a humidifying member 6, a humidifying heating means 7, and a casing 8 for accommodating them. In addition, the moisture absorbing and releasing member 3
Consists of an adsorption rotor, for example, a disc-shaped body formed of an adsorbent such as silica gel, zeolite, or alumina in a honeycomb shape or a porous particle shape, adsorbs moisture from flowing air, and releases moisture to heated air. It is configured as follows. In this case, the moisture absorbing / desorbing member 3 is pivotally supported by the casing 8 so as to be rotatable about its axis. The stacked sensible heat exchanger 5 has a plurality of flat passages stacked in a direction perpendicular to each other, and the first passage portions 9 orthogonal to each other.
And a second passage portion 10 for performing heat exchange by utilizing a difference in sensible heat between the air flowing through both passage portions 9 and 10.

The casing 8 is divided into a first chamber 11, a second chamber 12, a third chamber 13, and a fourth chamber 14 by a partition plate S. 12 constitutes a first humidity control passage 16, and the third chamber 13 and the fourth chamber 14 constitute a second humidity control passage 17. Also,
The opening of the first chamber 11 is an outdoor-side suction port 18 of the first humidity control passage 16, the opening of the second chamber 12 is an indoor-side outlet 19 of the first humidity control passage 16, and the third chamber 13 The opening of the second humidity control passage 17 serves as the indoor-side suction port 20, and the opening of the fourth chamber 14 serves as the outdoor-side air outlet 21 of the second humidity control passage 17.
An air supply fan 23 is provided in the second chamber 12, and an exhaust fan 24 is provided in the fourth chamber 14. Also,
The regeneration heating means 4 is composed of, for example, a heater or the like.
The fourth chamber 14 of the humidity control passage 17 is interposed between the moisture absorbing / desorbing member 3 and the laminated sensible heat exchanger 5.

In this case, the humidifying member 6 is a permeable membrane humidifying element. The moisture-permeable membrane humidifying element is, for example, provided with a large number of moisture-permeable membrane pipes, immersing the outside with water, and imparting moisture to the air passing inside the pipe, removing impurities with fine holes, Clean and healthy humidification is possible. The humidifying member 6 is disposed in the second chamber 12, and the humidifying heating means 7 includes, for example, a heater or the like like the heating means 4, and is provided in the second chamber of the first humidity control passage 16. In 12, it is interposed between the humidifying member 6 and the laminated sensible heat exchanger 5.

As shown in FIG. 2, the humidity control apparatus 1 is installed in the back of the ceiling of a building or the like. The outdoor suction port 18 is connected to a suction pipe 25, and the outdoor blow port 21 is connected to an outdoor exhaust pipe. The indoor suction port 20 is connected to a pipe 27 for indoor air, and the indoor outlet 19 is connected to a connection pipe 28 connected to the temperature control device 2. The indoor air pipe 27 has a plurality of branch pipes 29.
Are open to each room such as kitchen, toilet, bathroom, storage room, etc.

Next, the humidity control apparatus 1 configured as described above
The case of performing the dehumidifying ventilation operation by the following will be described. In this case, since humidification is not performed, the humidifying member 6 is set to a state where it does not function as a humidifier. That is, the water of the humidifying member 6 is drained, and the air passing through the humidifying member 6 is kept in a state in which no moisture is applied. In this state, the moisture absorbing and releasing member 3
Is driven (rotated) to drive the air supply fan 23, the outside air OA is sucked into the first chamber 11 of the first humidity control passage 16 from the outdoor suction port 18. The outside air OA passes through an air filter (not shown) to remove foreign matter such as dust, and then flows into the moisture absorbing and releasing member 3, where moisture is adsorbed and dried, and the moisture absorbing and releasing member The temperature is raised by the heat of adsorption of the air, and the air becomes high-temperature dehumidified air and flows out of the hygroscopic member 3. Then, the high-temperature dehumidified air further flows into the first passage portion 9 of the sensible heat exchanger 5, where the sensible heat of the dehumidified air is deprived to an appropriate temperature. Second passage 10 of heat heat exchanger 5
Is passed through the room air, heat is exchanged with the room air to reach an appropriate temperature, and flows out of the first passage portion 9. Thereafter, the dehumidified air SA (air supply) flows into the second chamber 12. In this case, since the humidifying member 6 does not perform the humidifying function as described above, this air is supplied from the indoor-side outlet 19 to the temperature control device 2 while being dehumidified.

On the other hand, when the exhaust fan 24 is driven, the room air RA (air in the kitchen, toilet, etc.) is sucked into the third chamber 13 of the second humidity control passage 17 from the indoor side suction port 20,
Further, it flows into the second passage 10 of the sensible heat exchanger 5.
The indoor air RA is supplied to the outdoor air O passing through the first passage 9.
A is performed, and after being preheated here, this second
It flows out of the passage 10 and is further heated by flowing through the heating means 4. Then, when the heated air flows into the moisture absorbing and releasing member 3, moisture is released from the moisture absorbing and releasing member 3, and the moisture absorbing and releasing member 3 is regenerated. At this time, the heated air absorbs this moisture, and air EA (exhaust) containing moisture is discharged from the outdoor outlet 21 to the outside through the exhaust pipe (ventilation pipe) 26 to the outside.

In this case, the moisture absorbing / desorbing member 3 includes a portion located in the first humidity control passage 16 as a dehumidification passage and a portion located in the second humidity control passage 17 as a regeneration passage. Each forms an air passage. That is, the portion located in the first humidity control passage 16 is the first air passage 30, and the portion located in the second humidity control passage 17 is the second air passage 31. Since the moisture absorbing / desorbing member 3 is rotating, the portion located in the first humidity control passage 16 as a dehumidifying passage is next located in the second humidity control passage 17 as a regeneration passage and is regenerated. As a result, it is located again in the first humidity control passage 16. Hereinafter, this step will be repeated. Therefore, the moisture absorbing / desorbing member 3 has the first and second air passages 30 and 31, and the portion that sequentially corresponds to the first humidity control passage 16 becomes the first air passage 30, 1 air passage 3
0 is a dehumidification passage, and a portion that sequentially corresponds to the second humidity control passage 17 is a second air passage 31, and the second air passage 31 is a regeneration passage. For this reason, the moisture absorbing / desorbing member 3 can repeatedly absorb and release the moisture, constantly dehumidify the outside air OA, and supply it to the temperature control unit 2.

Next, the humidifying ventilation operation of the humidity control apparatus 1 will be described. In this case, if the air supply fan 23 is driven, the low-temperature (for example, about 0 ° C.) outside air OA enters the first chamber 11 and then passes through the first chamber 11 to the sensible heat exchanger 5. enter. In this case, the moisture absorption / release member 3 is stopped, and does not function as a dehumidifier. On the other hand, the room air RA heated by the temperature control device 2 and the like and relatively warm enters the third chamber 13 and enters the sensible heat exchanger 5. In this case, the first passage 9
The sensible heat is exchanged between the air flowing through the air and the air flowing through the second passage 10, the outside air is heated by the room air, and the room air RA is cooled by the outside air. And the indoor air RA
Is discharged from the sensible heat exchanger 5 into the fourth chamber 14 having the moisture absorbing / desorbing member 3 which is stopped and does not exhibit the regenerating function, and is exhausted from the outdoor outlet 21 to the outside via the exhaust pipe 27. Is done. The outside air O flowing out of the sensible heat exchanger 5
A is heated by the heating means 7, passes through the humidifying member 6 functioning as a humidifier, and flows into the temperature control device 2 from the indoor-side outlet 19 through the connection pipe 28. For this reason,
The outside air is supplied with moisture by the humidifying member 6, and is supplied to the temperature control device 2 as fresh air containing appropriate humidity.

Incidentally, the temperature control device 2 comprises a compressor,
An outdoor heat exchanger, a decompression mechanism, an indoor heat exchanger, etc., and the outdoor heat exchanger functioning as an evaporator,
A heating operation is performed by making the indoor heat exchanger function as a condenser, and a cooling operation is performed by making the indoor heat exchanger function as a condenser and the indoor heat exchanger functions as an evaporator. Things. The connection pipe 28 is connected to the indoor unit 33 in which the indoor heat exchanger and the like are arranged. In addition, in this indoor unit 33,
Temperature controlled air piping 3 connected to rooms such as living rooms and living rooms
4 are connected. Thus, the temperature-controlled air is supplied from the indoor unit 33 to each room through the temperature-controlled air pipe 34.

That is, in this air conditioning system, the humidity control device 1 and the temperature control device 2 are connected by a signal line 15 as shown in FIG. The temperature is controlled by the temperature control device 2 to make each room a comfortable space at an appropriate temperature and containing appropriate moisture. As shown in Table 1, the operation modes of the humidity control apparatus 1 include ventilation, dehumidification ventilation, and humidification ventilation, and there are cases where these operation modes are manually switched and cases where the operation modes are automatically switched.

Outside air detection means 36 for detecting humidity and temperature of outside air;
An external air comparing means 37 for comparing the target absolute humidity with the humidity of the external air (absolute humidity); an external air controlling means 39 for performing an operation based on the external air comparing means 37; Is to control the heating capacity of the regenerating heating means 4 so as to approach the target absolute humidity. Here, "controlling the heating capacity of the regeneration heating means 4 so that the detected absolute humidity approaches the target absolute humidity"
Specifically, according to the conditions of the outside air temperature and the outside air humidity, the target regeneration air temperature that keeps the indoor humidity at a comfortable humidity is determined, the target regeneration air is compared with the current regeneration air temperature, and feedback control is performed. The capacity (capacity) of the heating means 4 is increased or decreased to bring the temperature of the regeneration air closer to the target temperature. Therefore, target regeneration temperature (target regeneration air temperature)
Is created in advance with a table of the relationship between the regeneration temperature (outlet temperature of the heating means 4) and the humidity (outside air absolute humidity), and is set based on this table. Therefore, in this control, as shown in the flowchart of FIG. 5, the comparison between the target absolute humidity and the detected absolute humidity is replaced with the difference between the target regeneration temperature and the current regeneration temperature. Further, the outside air detection means 36 detects the temperature with, for example, a temperature thermistor or the like,
For example, the humidity is detected by a dry-wet bulb thermometer or the like, and the comparing means 37 and the control means 39 are configured by an integrated circuit having a microcomputer function.

Next, this dehumidifying operation control method will be described with reference to the flowchart of FIG. After starting, it is first determined in step S1 whether or not the vehicle is in operation. If the vehicle is not in operation, the control is terminated. If driving, step S
Then, it is determined whether or not this operation mode is the dehumidification operation. If the operation is not the dehumidifying operation, the control is terminated. If it is a dehumidifying operation, the process proceeds to step S3. Then, a judgment delay timer (not shown) is set. Thereafter, the process proceeds to step S4, in which the target regeneration temperature (target regeneration air temperature) and the current regeneration temperature (current regeneration air temperature) are set.

Move to step S6. In step S5, it is determined whether or not the difference between the target regeneration temperature and the current regeneration temperature is equal to or greater than the predetermined value Y. If the value is not equal to or more than the predetermined value Y, the process proceeds to step S7. If the value is equal to or more than the predetermined value Y, the energization amount of the heating means for regeneration 4 is increased (up) to increase the dehumidification amount. I do. In step S7, it is determined whether the difference between the target regeneration temperature and the current regeneration temperature is smaller than the predetermined value X. If it is small, the process proceeds to step S6. If it is small, the amount of electricity supplied to the regeneration heating means 4 is decreased (down) to reduce the amount of dehumidification, and thereafter, the process proceeds to step S6. In step S6, it is determined whether or not the determination delay time of this control has elapsed. If so, the process returns to the original state of the start.

In FIG. 5, the predetermined value X is
If it is smaller than this, it is a dehumidification outdoor reference value that may cause too much dehumidification to obtain comfortable humidity,
The predetermined value Y is a dehumidifying outdoor-side reference value at which the dehumidifying amount may be insufficient to obtain comfortable humidity if it becomes larger than this. By performing the control shown in FIG. 5 in this manner, if the amount of dehumidification is insufficient, the amount of dehumidification is increased, and if the amount of dehumidification is large, the amount of dehumidification is decreased, and the room is brought closer to comfortable humidity. . In addition, wasteful dehumidification is performed, which contributes to energy saving.

As shown in FIG. 4, the humidity control apparatus includes an indoor setting means 35A for setting the indoor comfortable humidity.
And indoor detecting means 36A for detecting indoor humidity, and indoor comparing means 37 for comparing the detected humidity with the set humidity.

A dry-wet bulb thermometer or the like is used, and the comparing means 37A and the control means 39A are constituted by an integrated circuit or the like having a microcomputer function.
9 may also be used.

Next, a dehumidifying operation control method using the indoor setting means 35A, indoor detecting means 36A, indoor comparing means 37A, control means 39A and the like will be described with reference to the flowchart shown in FIG. After starting, it is first determined in step S8 whether or not the vehicle is running. If not, the control is terminated. If the operation is being performed, the process proceeds to step S9, and it is determined whether the operation mode is the dehumidification operation. If the operation is not the dehumidifying operation, the control is terminated. If it is a dehumidifying operation, the process proceeds to step S10. Then, the judgment delay timer is set. Thereafter, the process proceeds to step S11 to determine a difference between the target humidity and the current room humidity. That is, it is determined whether this difference is equal to or greater than the predetermined value X and smaller than the predetermined value Y. If it is out of the range, the process proceeds to step S12. If it is in the range, the process proceeds to step S1.
Move to 3. In step S12, it is determined whether or not the difference between the target humidity and the current indoor humidity is equal to or greater than the predetermined value Y. If the value is not equal to or more than the predetermined value Y, step S
The program proceeds to step S14, and when the value is equal to or more than the predetermined value Y, the amount of electricity supplied to the heating means 4 for regeneration is increased (increased) to increase the amount of dehumidification. Thereafter, the procedure proceeds to step S13. Step S1
At 4, it is determined whether or not the difference between the target humidity and the current indoor humidity is smaller than the predetermined value X. If it is smaller, the process proceeds to step S13, and if smaller, the amount of electricity supplied to the heating means for regeneration 4 is decreased (down), the amount of dehumidification is reduced, and thereafter, the process proceeds to step S13. In step S13,
It is determined whether or not the determination delay time of this control has elapsed,
If it has passed, it returns to the original state of the start.

In FIG. 6, the predetermined value X is
If it is smaller than this, it is a dehumidification indoor side reference value that may cause too much dehumidification to obtain comfortable humidity,
The predetermined value Y is a dehumidification indoor-side reference value at which the dehumidification amount may be insufficient to obtain comfortable humidity if it becomes larger than this. When the control as shown in FIG. 6 is performed as described above, the current humidity in the room is compared with the target comfortable humidity, and the capacity (capacity) of the heating means 4 is increased or decreased by feedback control so as to approach the target humidity. Therefore, it is possible to more stably maintain the comfortable humidity.

When the dehumidifying operation is started, the control shown in FIG. 5 may be performed, and the control shown in FIG. 6 may be performed after a lapse of a predetermined time. That is, a dehumidifying operation in which the indoor air approaches the target humidity is performed by the control shown in FIG. 5, and after a lapse of a predetermined time, a dehumidifying operation in which the indoor humidity approaches the target humidity is performed by the control shown in FIG. It is possible to perform a highly accurate dehumidifying operation in a shorter time, which greatly contributes to energy saving.

By the way, even during the humidification ventilation operation, the operation as shown in the flowchart of FIG. 7 and the operation as shown in the flowchart of FIG. 8 can be performed. That is, in FIG.
The heating capacity of the humidifying heating means 7 is controlled so that the absolute humidity detected in the step (2) approaches the target absolute humidity. In FIG. 8, the humidity detected by the indoor detecting means 36A becomes the target humidity. The heating capacity of the humidifying heating means 7 is controlled so as to approach. Further, in the control method shown in FIG. 7, a table of the relationship between the humidification temperature (the outlet temperature of the heating means 7) and the humidity (outside air absolute humidity) is created in advance, and the target humidification temperature is set based on this table. Control is performed based on the difference between the target humidification temperature and the current humidification temperature.

Next, the humidifying operation control method shown in the flowchart of FIG. 7 will be described. After starting, it is first determined in step S15 whether or not the vehicle is in operation. If not, the control is terminated. If the operation is being performed, the process proceeds to step S16, and it is determined whether the operation mode is the humidification operation.
If the operation is not the humidification operation, the control ends. If it is a humidification operation, the process proceeds to step S17. And

Then, the difference between the target humidification temperature and the current humidification temperature is determined. That is, when the difference is equal to or greater than the predetermined value X,
It is determined whether it is smaller than. If it is out of the range, the process proceeds to step S19, and if it is in the range, the process proceeds to step S20. In step S19, it is determined whether or not the difference between the target humidification temperature and the current humidification temperature is equal to or greater than the predetermined value Y. And if not more than the predetermined value Y,
The process proceeds to step S21, and when the value is equal to or more than the predetermined value Y, the amount of electricity supplied to the humidifying heating means 7 is increased (increased) to increase the amount of humidification, and thereafter, the process proceeds to step S20. In step S21, it is determined whether or not the difference between the target humidification temperature and the current humidification temperature is smaller than the predetermined value X. If the value is smaller, the process proceeds to step S20. If the value is smaller, the amount of electricity supplied to the humidifying heating unit 7 is decreased to reduce the amount of humidification. Thereafter, the process proceeds to step S20. In step S20, it is determined whether or not the determination delay time of this control has elapsed, and if it has elapsed, the state returns to the original state of the start.

By the way, in FIG. 7, the predetermined value X is
If it is smaller than this, it is a humidification outdoor reference value that may increase the humidification amount too much to obtain comfortable humidity,
The predetermined value Y is a humidification outdoor reference value that may increase the humidification amount in order to obtain comfortable humidity if it becomes larger than this. By performing the control shown in FIG. 7 in this manner, if the humidification amount is insufficient, the humidification amount is increased, and if the humidification amount is large, the humidification amount is decreased, and the room approaches the comfortable humidity. . This contributes to energy saving without performing unnecessary humidification.

Next, the humidification control method shown in the flowchart of FIG. 8 will be described. Start, first step S2
It is determined in step 2 whether or not the vehicle is running. If not, the control is terminated. If the operation is being performed, the process proceeds to step S23, and it is determined whether the operation mode is the humidification operation. If the operation is not the humidification operation, the control ends. If it is a humidification operation, the process proceeds to step S24. Then, the judgment delay timer is set. Thereafter, the process proceeds to step S25 to determine the difference between the target humidity and the current room humidity. That is, it is determined whether this difference is equal to or greater than the predetermined value X and smaller than the predetermined value Y. If it is out of the range, the process proceeds to step S26. If it is in the range, the process proceeds to step S2.
Move to 7. In step S26, it is determined whether or not the difference between the target humidity and the current indoor humidity is equal to or greater than the predetermined value Y. If the value is not equal to or more than the predetermined value Y, step S

At 8, it is determined whether or not the difference between the target humidity and the current indoor humidity is smaller than the predetermined value X. If it is not small, the process proceeds to step S27, and if it is small, the amount of electricity supplied to the humidifying heating means 7 is decreased (down) to reduce the amount of humidification, and thereafter, the process proceeds to step S27. In step S27, it is determined whether or not the determination delay time of this control has elapsed, and if it has elapsed, the process returns to the original state of the start.

In FIG. 8, the predetermined value X is
If it is smaller than this, it is a humidification indoor side reference value that may increase the humidification amount too much to obtain comfortable humidity,
The predetermined value Y is a humidification indoor-side reference value at which the humidification amount may be insufficient to obtain a comfortable humidity if it becomes larger than this. Thus, the current humidity in the room and the target comfortable humidity are compared, and the humidifying heating means 7 is controlled by feedback control.
By increasing / decreasing the capacity (capacity) of the battery so as to approach the target humidity, it is possible to more stably maintain the comfortable humidity.

When the humidification operation is started, the control shown in FIG. 7 may be performed, and the control shown in FIG. 8 may be performed after a lapse of a predetermined time. That is, a humidifying operation in which the indoor air approaches the target humidity is performed by the control shown in FIG. 7, and after a lapse of a predetermined time, a humidifying operation in which the indoor humidity approaches the target humidity is performed by the control shown in FIG. The humidifying operation can be performed in a short time with high accuracy, which greatly contributes to energy saving.

Although the specific embodiment of the humidity control apparatus of the present invention has been described above, the humidity control apparatus of the present invention is not limited to the above embodiment, and can be implemented with various modifications. It is possible. For example, the humidity in the comfortable range
It can be changed to the one desired by the user. Further, in the illustrated example, the case where the temperature control device 2 is connected to the humidity control device 1 through the connection pipe 28 is shown, but the temperature control device 2 may be independent of the humidity control device. That is, the air conditioned by the humidity control device 1 is directly supplied to each room (room),
The temperature may be controlled by a temperature control unit (an indoor unit of an air conditioner) provided for each room.
