DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the air-conditioning ventilator of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall configuration diagram showing an embodiment of an air-conditioning ventilator of the present invention. This air-conditioning ventilator controls an indoor humidity control unit 2 that humidifies indoor air and blows the indoor air, and an outdoor air conditioned. A humidity control ventilating unit 1 that humidifies and blows indoors, and can perform ventilation, dehumidification ventilation, humidification ventilation, and the like in the humidity control ventilator 1.
, Cooling, heating, dehumidification, humidification, and the like can be performed.

As shown in FIG. 2, the humidity control ventilation unit 1 comprises a moisture absorbing / desorbing member 3, a regenerating heating means 4, a laminated sensible heat exchanger 5, a humidifying member 6, and a humidifying heating means. And a casing 8 for accommodating them. The moisture absorbing / desorbing member 3 is composed of a suction rotor, for example, is formed of a disc-shaped body formed of an adsorbent such as silica gel, zeolite, or alumina into a honeycomb shape or a porous granule, and adsorbs moisture from flowing air, It is configured to release moisture into the heated air. In this case, the moisture absorbing / desorbing member 3 is pivotally supported by the casing 8 so as to be rotatable about its axis. Further, the laminated sensible heat exchanger 5 is configured such that a plurality of flat passages in a direction perpendicular to each other are laminated, and a first passage 9 and a second passage 10 which are perpendicular to each other are formed.
The heat exchange is performed using the difference in sensible heat between the air flowing through zero.

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.

Then, the humidity control and ventilation unit 1 is configured as shown in FIG.
As shown in the figure, the outdoor air inlet 18 is connected to a suction pipe 25, the outdoor air outlet 21 is connected to an outdoor exhaust pipe 26, and the indoor air inlet 20 is for indoor air. The indoor side outlet 19 is connected to a pipe 27 and the connection pipe 28 connected to the indoor humidity control unit 2.
The indoor air pipe 27 has a plurality of branch pipes 29, and each branch pipe 29 is open to each room such as a kitchen, a toilet, a bathroom, and a storage room.

Next, as shown in FIG. 3, the indoor humidity control unit 2 includes a compressor 40, an outdoor heat exchanger 41, a pressure reducing mechanism 42, an indoor heat exchanger 43, Valve 44
The heating operation is performed by causing the outdoor heat exchanger 41 to function as an evaporator and the indoor heat exchanger 43 to function as a condenser.
Function as a condenser, and the indoor heat exchanger 43
Is operated as an evaporator to perform a cooling operation. The connection pipe 28 is connected to an indoor unit 33 in which an indoor heat exchanger and the like are arranged, and the indoor humidity control unit 2 and the humidity control ventilation unit 1 are connected by a signal line 15.
And are electrically connected. The indoor unit 33 is connected to a temperature control air pipe 34 connected to a room such as a living room or a living room. Thus, the temperature-controlled air is supplied from the indoor unit 33 to each room through the temperature-controlled air pipe 34.

The indoor humidification unit 2 is provided with a humidification unit (not shown) to enable a humidification operation. The humidifying unit may be, for example, a publicly known ultrasonic humidifier, a moisture-permeable membrane humidifying element used for the humidity control ventilation unit 1, or the like. It can be configured by using an adsorbent such as zeolite used in the above. In addition, the indoor humidity control unit 2 performs a dehumidifying operation by weak cooling, and mixes air that has been cooled down and has good humidity with air warmed by a reheater or the like and supplies the air to the room as refreshing air at an appropriate temperature. Reheat dehumidification operation is possible. Therefore, the indoor humidity control unit 2 can perform a humidifying / heating operation, a humidifying operation, and a reheating / dehumidifying operation in addition to the cooling (dehumidifying / cooling) operation and the heating operation.

Next, the case of performing the dehumidifying ventilation operation by the humidity control ventilation unit configured as described above 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, when the moisture absorbing / desorbing member 3 is operated (rotated) and the air supply fan 23 is driven, outside air OA is sucked into the first chamber 11 of the first humidity control passage 16 from the outdoor-side suction port 18. Is done. This outside air OA
After the foreign matter such as dust is removed by passing through an air filter (not shown), the dust flows into the moisture absorbing and releasing member 3, where the moisture is absorbed and dried, and the moisture absorbing and releasing member 3 is adsorbed. The temperature is raised by heat, and the air becomes high-temperature dehumidified air and flows out of the moisture absorbing and releasing member 3. Then, the high-temperature dehumidified air further flows into the first passage section 9 of the sensible heat exchanger 5,
Here, the sensible heat of the dehumidified air is deprived to an appropriate temperature, that is, the second temperature of the sensible heat exchanger 5 as described later.
Since the room air passes through the passage 10, heat exchange is performed with the room air to reach an appropriate temperature, and the first passage 9
Spill out of. Thereafter, the dehumidified air SA (air supply) flows into the second chamber 12. In this case, as described above, the humidifying member 6
Does not perform the humidifying function, so that the air is kept dehumidified and the indoor humidity control unit 2 is
Is supplied to

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 the 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 dehumidifying 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 defined as the first air passage 30, and the portion located in the second humidity control passage 17 is defined as 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 a portion that sequentially corresponds to the first humidity control passage 16 becomes the first air passage 30. The first air passage 30 serves as a dehumidifying passage, and a portion that sequentially corresponds to the second humidity control passage 17 serves as a second air passage 31, and the second air passage 31 serves as 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 humidification ventilation operation of the humidity control ventilation unit 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 is reduced to the first chamber 11.
After passing through the first chamber 11, it enters the sensible heat exchanger 5. In this case, the moisture absorbing and releasing member 3 is stopped.
Does not function as a dehumidifier. On the other hand, the room air RA heated by the indoor humidity control unit 2 or the like and relatively warm is
It enters the third chamber 13 and enters the sensible heat exchanger 5. In this case, the sensible heat is exchanged between the air flowing through the first passage 9 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. Then, the room air RA is supplied from the sensible heat heat exchanger 5 to the fourth
After entering the chamber 14, the air is exhausted from the outdoor air outlet 21 to the outside via the exhaust pipe 27. The outside air OA flowing out of the sensible heat exchanger 5 is heated by the heating means 7, passes through the humidifying member 6 functioning as a humidifier, passes through the indoor-side outlet 19 through the connection pipe 28, and is connected to the humidifier 6. It flows into the indoor humidity control unit 2. For this reason, the outside air is provided with moisture by the humidifying member 6 and is supplied to the indoor humidity control unit 2 as fresh air containing appropriate humidity.

As described above, the humidity control ventilator 1 can perform the dehumidification ventilation operation and the humidification ventilation operation as described above, and can also perform only the ventilation operation without dehumidification and humidification. When performing the ventilation operation without dehumidification and humidification, the rotation of the moisture absorption / release member 3 may be stopped, and the water of the humidification member 6 may be drained. Therefore, the air conditioning ventilator can perform ventilation, dehumidification ventilation, and humidification ventilation in the humidity control ventilation unit 1, and can perform indoor humidity control unit 2.
, Cooling, heating, dehumidification, and humidification can be performed. Therefore, a combination of operation modes as shown in the following Table 1 occurs, and in the shaded portion of Table 1, an operation mode in which the humidity control directions of both units are opposite (a so-called mode battery).
Occurs. In Table 1, the air conditioner indicates the indoor humidity control unit 2, the air conditioner operation mode is the operation mode of the indoor humidity control unit 2, and the ventilation operation mode is the operation mode of the humidity control ventilation unit 1.

[Table 1]

In view of this, in the present invention, the setting is made such that mode-battering or the like does not occur in the humidity control operation. That is, as described above, the indoor humidity control unit 2 and the humidity control ventilating unit 1 are electrically connected by the signal line 15 and, as shown in FIG. A judging means 36 for judging the mode switched by the switching means 35; Control means 37 for performing control is provided. The determining means 36 and the control means 37 are constituted by an integrated circuit or the like including the functions of the microcomputer. The humidity control ventilation unit 1 and the indoor humidity control unit 2 can be operated manually and automatically, respectively, and these can be switched by the switching means 35. Here, "manual" means that the user selects various operation modes and switches the switching means 35, and "automatic"
That is, various operation modes are automatically selected based on temperature, humidity, and the like, and the switching means 35 is switched.

The determining means 36 and the control means 37
In such a case, one of the units is prioritized so as to prevent the mode batting. That is, when both units 1 and 2 are in the automatic operation and are in the operation mode in which the humidity control directions are opposite to each other, the indoor humidity control unit 2 has priority.
When one is manual and the other is automatic, priority is given to the manual side. In this case, even if the humidity control ventilation unit 1 is manual, the indoor humidity control unit 2 may be manual. Further, when both units 1 and 2 are manual,
Priority is given to the side that is operated later (the boost side).

Specifically, as shown in FIG. 5, in step S1, it is determined whether or not the humidity control directions of both units 1 and 2 are in opposing operation modes. If the operation modes are contradictory, the process proceeds to step S2 to determine whether or not the indoor humidity control unit 2 is performing the cooling operation. If it is not the opposing operation mode in step S1, the process returns to the start. If it is determined that the cooling operation is performed in step S2, the process proceeds to step S3.
The operation that gives priority to the cooling operation is performed, and the process proceeds to step S4. If the cooling operation is not performed in step S2, the process proceeds to step S5, and it is determined whether one is manual and the other is automatic. If one is manual and the other is automatic, the operation proceeds to step S6, the operation is performed manually, and the operation proceeds to step S4. In step S5, if one is not manual and the other is not automatic, the process proceeds to step S7. In this step S7,
It is determined whether both units 1 and 2 are automatic. If both units 1 and 2 are in automatic operation, the process proceeds to step S8, where the priority operation of the indoor humidity control unit 2 is performed, and the process proceeds to step S4. If it is not automatic in step S7, since both units 1 and 2 are manual, the process proceeds to step S9, and the priority operation of the unit selected later (push priority)
And the process proceeds to step S4. In step S4, it is determined whether or not to end the operation. If the operation is to be ended, the operation is ended. If not, the operation returns to the start.

Next, the operation in the mode-battering, that is, the operation of the shaded portion in Table 1 will be described in more detail.
First, the case where the humidity control ventilation unit 1 is in the humidification ventilation mode and the indoor humidity control unit 2 is in the cooling mode will be described. The cooling operation is performed regardless of whether the indoor humidity control unit (air conditioner) 2 is operated manually or automatically. In addition, as shown in * 1, when the air conditioner 2 is boosted, the humidity control ventilation unit 1 is ventilated, and when the humidity control ventilation unit 1 is boosted, the humidity control ventilation unit 1 is operated.

When the humidity control ventilation unit 1 is in the humidification ventilation mode and the air conditioner 2 is in the cooling mode, if the humidity control ventilation unit 1 is automatic, the air conditioner 2 may be either manual or automatic. While performing the cooling operation, the ventilation operation of the humidity control ventilation unit 1 is performed.

The case where the humidity control and ventilation unit 1 is in the manual dehumidifying ventilation mode and the air conditioner 2 is in the humidifying and heating mode will be described.
As shown in FIG. 2, if the air conditioner 2 is boosted, the boosting priority is given. Therefore, the air conditioner 2 performs the humidifying and heating operation, the humidity control and ventilation unit 1 performs the ventilation operation, and if the humidity control and ventilation unit 1 is boosted, the boost is performed. Since the priority is given, the humidity control ventilation unit 1 performs dehumidification ventilation, and the air conditioner 2 performs a heating operation. When the humidity control ventilation unit 1 is in the manual dehumidification ventilation mode and the air conditioner 2 is in the humidifying and heating mode, and when the air conditioner 2 is in the automatic mode, priority is given to manual operation.
Performs dehumidification ventilation, and the air conditioner 2 performs a heating operation. Further, in the case where the humidity control ventilation unit 1 is in the automatic dehumidifying ventilation mode and the air conditioner 2 is in the humidifying and heating mode, if the air conditioner 2 is in the manual mode, the manual control is given priority. The ventilation unit 1 performs dehumidification ventilation, and if the air conditioner 2 is automatic, the air conditioner 2 has priority, the air conditioner 2 performs humidification heating operation, and the humidity control ventilation unit 1 performs dehumidification ventilation.

Further, the case where the humidity control and ventilation unit 1 is in the manual dehumidifying ventilation mode and the air conditioner 2 is in the humidifying mode will be described.
As shown in (2), if the air conditioner 2 is boosted, the boosting priority is given. Therefore, the air conditioner 2 performs the humidifying operation, the humidity control ventilation unit 1 performs the ventilation operation, and if the humidity control ventilation unit 1 is boosted, the boosting priority is given. Therefore, the humidity control and ventilation unit 1 performs the dehumidification and ventilation operation, and the air conditioner 2 is stopped (blowing). Also,
When the humidity control ventilation unit 1 is in the manual dehumidification ventilation mode and the air conditioner 2 is humidified, and when the air conditioner 2 is automatic, priority is given to manual operation. Therefore, the humidity control ventilation unit 1 performs the dehumidification ventilation operation, The air conditioner 2 is stopped (blowing). Further, when the humidity control ventilation unit 1 is in the automatic dehumidification ventilation mode and the air conditioner 2 is in the humidification mode,
If the air conditioner is manual, the air conditioner 2 has a manual priority, so that the air conditioner 2 performs the humidifying operation, and the humidity control ventilation unit 1 performs the ventilation operation. The humidity control ventilation unit 1 performs a ventilation operation.

Next, a case where the humidity control ventilation unit 1 is in the humidification ventilation mode and the air conditioner 2 is in the dehumidification operation mode (in this case, the reheat dehumidification operation mode) will be described. In this case, as shown in * 4, if the air conditioner 2 is boosted, the boosting is prioritized. Therefore, the air conditioner 2 performs the dehumidification operation, the humidity control ventilation unit 1 performs the ventilation operation, and the humidity control ventilation unit 1 performs the boost operation. If there is, the boosting priority is given, so that the humidity control ventilation unit 1 performs the humidification ventilation operation, and the air conditioner 2 performs the ventilation operation or stops. Further, when the humidity control ventilation unit 1 is in the humidification ventilation mode and the air conditioner 2 is in the reheat dehumidification operation mode, if the air conditioner 2 is automatically and the humidity control ventilation unit 1 is in the manual mode, the manual priority is given. The humidity control and ventilation unit 1 performs the humidification and ventilation operation, and the air conditioner 2 performs the stop (blowing) operation. Furthermore, when the humidity control ventilation unit 1 is in the humidification ventilation mode and the air conditioner 2 is in the dehumidification (reheat dehumidification) operation mode, when the humidity control ventilation unit 1 is automatic and the air conditioner 2 is manual, it is manually operated. A certain air conditioner 2 has a priority and performs a dehumidification (reheat dehumidification) operation by the air conditioner 2, a humidity control ventilation unit 1 performs a ventilation operation, and when both units 1 and 2 are automatic, a priority is given to the air conditioner 2. , (Reheat dehumidification), and the humidity control ventilation unit 1 performs a ventilation operation.

As described above, according to the air-conditioning ventilator described above, the boosting priority, the indoor humidity control unit priority, and the manual priority can be skillfully used properly, thereby conserving energy. At the same time, the operation mode is set to be the best operation mode for the user. That is,

Although the specific embodiment of the air-conditioning ventilator of the present invention has been described above, the air-conditioning ventilator of the present invention is not limited to the above-described embodiment, and may be implemented with various modifications. It is possible. For example,
The humidity control ventilation unit 1 may have no humidification function or may have no dehumidification function. In the case where the humidification function is not provided, only ventilation is required in the humidification mode. In the case where there is no dehumidification function, only ventilation is required in the dehumidification mode. Further, the indoor humidity control unit 2 may not have a humidifying function or may have no dehumidifying function. In addition, both the humidity control ventilation unit 1 and the indoor humidity control unit 2 may be manual only or automatic only, and when one unit is only manual, the other can be switched between manual and automatic. Or the other may be automatic only.
