DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the air conditioner of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an overall block configuration diagram of a first embodiment of the present invention. In the figure, 1 is a substantially tongue-shaped separation block, and this separation block 1 is a lithium chloride LiCl that has been fed.
It is for concentrating and diluting the hygroscopic liquid 10 consisting of. A plus electrode 5 and a minus electrode 6 are arranged on both sides of the separation block 1. And both electrodes 5, 6
A plurality of ion exchange devices 2 each consisting of an anode film 3 and a cathode film 4 are arranged at a predetermined interval in the separation block 1 between them. Here, each cathode film 4 and anode film 3
In the portion (room) between and, the room where the hygroscopic liquid 10 is concentrated is referred to as the concentrating chamber 7, and the room where it is diluted is referred to as the diluting chamber 8. The concentration chamber 7 of the separation block 1 is connected by a pipe 11 and is connected via a solenoid valve 21 to a first moisture absorption / desorption unit 13 that dehumidifies or humidifies indoor air. Further, the diluting chamber 8 of the separation block 1 is connected by a pipe 12 and is connected via a solenoid valve 23 to a second moisture absorbing / releasing unit 14 that releases moisture to / from outdoor air. The concentrating chamber 7 is a pipe 1 in which a solenoid valve 22 is provided.
1a to the second moisture absorbing / releasing unit 14, and the dilution chamber 8 to the first by the pipe 12a provided with the solenoid valve 24.
Each of them is also connected to the moisture absorbing / releasing unit 13.

The moisture absorbing / releasing units 13 and 14 are each provided with a plurality of tubes 15 made of a porous film or the like through which the moisture absorbing liquid 10 circulated from the separation block 1 passes. It has a structure that makes it in contact with indoor and outdoor air. A fan 16 for blowing air is provided, and air is blown by the fan 16 so as to come into contact with the outer peripheral surface of the tube 15 inside.

The first moisture absorbing / releasing unit 13 and the second moisture absorbing / releasing unit 14 are connected via pipes 26 and 27 to a tank 28 for temporarily storing the moisture absorbing liquid 10, respectively. The pump 29 that circulates the hygroscopic liquid 10 is
8 is provided in the middle of a pipe 30 connecting the separation block 1 and the separation block 1. The pump 29 circulates the hygroscopic liquid 10 throughout the circuit. Further, the pipes 30 on the discharge side of the pump 29 are separated from each other, and the hygroscopic liquid 10 is sent to each room (concentration chamber 7, dilution chamber 8) between the anode film 3 and the cathode film 4 of the separation block 1. I am trying. The tip of the pipe 30 shown in FIG. 1 is divided into the concentrating chamber 7 and the diluting chamber 8 to feed the hygroscopic liquid 10. However, the tip of one pipe 30 is parallel to the concentrating chamber 7 and the diluting chamber. Alternatively, the hygroscopic liquid 10 may be sent to each of the eight.

Next, the operation will be described. Solenoid valve 2
1 and 23 are opened, the other solenoid valves 22 and 24 are closed, and the first moisture absorption / desorption unit 13 is dehumidified in the room.
A case will be described in which the second moisture absorption / desorption unit 14 is dehumidified to the outdoor air, that is, the regeneration operation is performed. The hygroscopic liquid 10 in the system is circulated by driving the pump 29, and the hygroscopic liquid 10 is concentrated by the ion exchange device 2 in the separation block 1.
Dilution is done. That is, the cations Li ⁺ of the hygroscopic liquid 10 permeate the ion exchange membrane of each cathode membrane 4 of the ion exchange device 2 and collect in the concentration chamber 7. Also, the hygroscopic liquid 1
Anions Cl ^{− of} 0 are each anode membrane 3 of the ion exchange membrane 2.
Permeate through the ion exchange membrane of the above and collect in the concentrating chamber 7. Then, the water remains in the diluting chamber 8, the hygroscopic liquid 10 in the concentrating chamber 7 becomes a concentrated liquid, and the hygroscopic liquid 10 in the diluting chamber 8 becomes a diluting liquid. That is, the hygroscopic liquid 10 is converted into cation Li by the ion exchange device 2.
It is separated into ⁺ , anion Cl ^−, and water. Therefore, when viewed from the left side, the room between the cathode film 4 and the anode film 3 becomes a concentrating room 7 in which lithium chloride (moisture absorbing liquid 10) is concentrated, and the room between the anode film 3 and the cathode film 4 is linium chloride ( It becomes the dilution chamber 8 in which the hygroscopic liquid 10) is diluted.

The concentrated moisture absorbing liquid 10 collected in the concentration chamber 7 of the separation block 1 is sent to the first moisture absorbing / releasing unit 13 via the pipe 11 and the solenoid valve 21, and the first moisture absorbing / releasing unit 13 absorbs moisture. When the liquid 10 passes through the tube 15, the liquid 10 comes into contact with the room air to absorb the moisture contained in the room air, so that the first moisture absorption / desorption unit 13 performs the dehumidification operation. Then, the hygroscopic liquid 10 which has been absorbed by the first moisture absorbing / releasing unit 13 and diluted is returned to the tank 28 via the pipe 26. On the other hand, the diluted hygroscopic liquid 10 collected in the diluting chamber 8 of the separation block 1 is connected to the pipe 12 and the solenoid valve 23.
Is sent to the second moisture absorbing / releasing unit 14 through the second moisture absorbing / releasing unit 14, and when the moisture absorbing liquid 10 passes through the tube 15 and comes into contact with outdoor air, the moisture contained in the moisture absorbing liquid 10 The regeneration operation is performed to release. Then, the moisture absorbing liquid 10 concentrated in the second moisture absorbing / releasing unit 14 is returned to the tank 28 via the pipe 27. Further, on both sides of the separation block 1, only cations or anions are collected and therefore do not contribute much to concentration and dilution, so these are returned to the tank 28 by the pipes 31 and 32.

Here, a voltage of 0 V to 10 V is applied between the plus electrode 5 and the minus electrode 6 which are located on both sides of the separation block 1 and are immersed in the hygroscopic liquid 10. The voltage value applied to the brass electrode 5 and the minus electrode 6 is 0 to 1 depending on the required concentration of the hygroscopic liquid 10.
It is appropriately set within the range of about 0V. Therefore, the hygroscopic liquid 10 is usually concentrated and diluted by the ion exchange device 2 by applying a voltage of an appropriate value as described above. However, even when the voltage is not applied between the electrodes 5 and 6, the ion exchange is performed. When the hygroscopic liquid 10 can be concentrated and diluted by the device 2, no voltage may be applied.

Further, although the number of the anode film 3 and the number of the cathode film 4 of the ion exchange device 2 are three, respectively, the number may be increased or decreased depending on the degree of concentration and dilution of the hygroscopic liquid 10.

In this embodiment, the first moisture absorbing / releasing unit 13 is in the dehumidifying operation and the second moisture absorbing / releasing unit 14 is in the regenerating operation. However, the first moisture absorbing / releasing unit 13 is in the indoor humidifying operation, and the second moisture absorbing / releasing operation is performed. The unit 14 can be switched to the moisture absorption (regeneration) operation. That is, the solenoid valves 21, 23
Is closed and the solenoid valves 22 and 24 are opened, the path of the hygroscopic liquid 10 can be changed, and the first moisture absorbing / releasing unit 13 is subjected to the humidifying operation and the second moisture absorbing / releasing unit 14 is operated.
Can be regenerative driving. In this case, when water supply to the dehumidifying module (moisture absorption / desorption units 13 and 14) is insufficient, water supply may be performed by the water supply means 33 such as tap water. Also, open the solenoid valve 21 ...
It is also possible to carry out the close control so that only one of the moisture absorbing / releasing units 13 (or 14) is in the dehumidifying operation or the humidifying operation. Further, the number of moisture absorbing / releasing units is not limited to two, and it is also possible to connect in parallel to provide a plurality of moisture absorbing / releasing units and install them in accordance with the number in the room. Further, at the time of indoor dehumidification, the higher the temperature of the hygroscopic liquid 10, the easier it is to release the water contained in the hygroscopic liquid 10. Therefore, during the regenerating operation of the second moisture absorbing / releasing unit 14, cooling exhaust heat is applied to absorb moisture. The liquid 10 may be heated. Further, it is possible to use both the moisture absorbing / releasing units 13 and 14 both indoors, or to use the first moisture absorbing / releasing unit 13 outdoors and the second moisture absorbing / releasing unit 14 indoors.

By the way, as specific examples of the ion exchange membranes of the anode membrane 3 and the cathode membrane 4 of the above-mentioned ion exchange apparatus 2, there are generally two types of hydrocarbon ion exchange membranes and fluorine ion exchange membranes. Among them, the hydrocarbon ion exchange membrane is a styrene / divinylbenzene copolymer as a base material, to which a sulfone group or a quaternary amine group is introduced, and a synthetic fiber cloth or the like for improving mechanical strength. It is used for the core material. As a hydrocarbon-based ion exchange membrane, a crosslinked homogeneous membrane made of a styrene / divinylbenzene copolymer is subjected to a sulfonation or amination reaction, and as a modification by the surface treatment of the membrane, the cation exchange membrane surface is treated with a cationic component. A monovalent ion selective permeable membrane in which a branched electrolyte is attached to reduce the fixed ion concentration on the surface or the degree of dissociation is reduced to suppress permeation of divalent or higher cations may be used. Further, for the purpose of preventing surface contamination by organic anions, an anion exchange membrane which is resistant to organic matter contamination and which has a reduced charge density on the surface or has a slight amount of cation groups introduced on the surface may be used. The fluorine-based ion exchange membrane is generally a hydrocarbon-based ion exchange membrane to which a fluororesin is added. Also forming a reaction with charged groups and a carboxyl group and OH group _SO 3 Na _NH 4 Cl polysulfone membrane ^{_{(-NR 4 +, -SO 3 -}} ) charged membrane that is may be used.

FIG. 2 shows a second embodiment. In this embodiment, two tanks 41 and 42 for storing the hygroscopic liquid 10 are installed, and the moisture absorbing / releasing unit 1 is constituted by a concentrating tank 41 and a diluting tank 42.
This is an example of a circuit suitable for feeding the concentrated liquid and the diluting liquid to 3 and 14 and for separating the concentration of the hygroscopic liquid 10 into the tanks 40 and 41 without sending it to the moisture absorbing / releasing units 13 and 14. That is, when the first moisture absorbing / releasing unit 13 is in the dehumidifying operation and the second moisture absorbing / releasing unit 14 is in the humidifying or regenerating operation, the feed side of the concentrating chamber 7 of the separation block 1 has a pipe 42 indicated by a solid line. One end is connected to each other, and the other end of the pipe 42 is connected to the pipe 43. The tip of the pipe 43 branches into a pipe 44 and a pipe 45, and one pipe 44 is connected to the first moisture absorbing / releasing unit 13 via an electromagnetic valve 35. An electromagnetic valve 36 is interposed in the other pipe 45 and is connected to a pipe 46 for returning the absorbed liquid 10 from the first moisture absorbing / releasing unit 13 to the tank 40. Also, the hygroscopic liquid 1 in the tank 40
Pipes 47 for supplying 0 to the concentration chamber 7 of the separation block 1 are provided via a pump 48.

Further, one end of a pipe 51 shown by a broken line is connected to the feed side of the diluting chamber 8 of the separation block 1, and the other end of the pipe 51 is connected to the pipe 52. The tip of the pipe 52 is branched into a pipe 53 and a pipe 54, and one pipe 53 is provided with a solenoid valve 37 so that the second moisture absorbing / releasing unit 1
Connected to 4. An electromagnetic valve 38 is interposed in the other pipe 54 and is connected to a pipe 55 for returning the hygroscopic liquid 10 from the second moisture absorbing / releasing unit 14 to the tank 41. Also the tank 41
Pipes 56 for supplying the hygroscopic liquid 10 therein to the diluting chamber 8 of the separation block 1 are provided via a pump 57.

Next, the operation will be described. First, the case where the first moisture absorbing / releasing unit 13 is dehumidified and the second moisture absorbing / releasing unit 14 is humidified or regenerated is described. In this case, the solenoid valves 36 and 38 are closed and the solenoid valves 35 and 37 are controlled to be open. Ion exchange device 2 in separation block 1

The absorbed moisture is absorbed, and the hygroscopic liquid 10 having absorbed this moisture is returned to the tank 40 via the pipe 46. The hygroscopic liquid 10 in the tank 40 is sent to the concentrating chamber 7 of the separation block 1 via the pump 48 and the pipe 47, respectively, and concentrated and diluted. Repeat this for tank 4
In 0, the concentration chamber 7 of the separation block 1 and the moisture absorbing / releasing unit 1
The hygroscopic liquid 10 circulating in 3 is stored.

On the other hand, the diluted hygroscopic liquid 10 is collected in the diluting chamber 8 of the separation block 1, and the diluted hygroscopic liquid 1 is collected.
0 is sent to the second moisture absorbing / releasing unit 14 via the pipes 51, 52, 53 and the solenoid valve 37. In the second moisture absorbing / releasing unit 14, the moisture contained in the moisture absorbing liquid 10 is discharged into the room to perform the humidifying operation (or the regenerating operation to release it outside).
The moisture absorbing liquid 10 concentrated in the second moisture absorbing / releasing unit 14 is returned to the tank 41 via the pipe 55. And tank 4

Next, the moisture absorbing liquid 10 is absorbed by the moisture absorbing / releasing unit 13,
A case will be described in which the hygroscopic liquid 10 is used for concentration separation without being sent to 14. In this case, the solenoid valves 35 and 37 are closed, and the solenoid valves 36 and 38 are controlled to open. By keeping the solenoid valves 35 and 37 in the closed state, the moisture absorbing liquid 10 from the concentrating chamber 7 and the diluting chamber 8 of the separation block 1 is not sent to the moisture absorbing / releasing units 13 and 14, and the solenoid valves 36 and 38, the piping It is sent to the tanks 40 and 41 via 46 and 55 for circulation.

Moreover, even if the DC voltage is not applied between the positive electrode and the negative electrode, the hygroscopic liquid can be separated into the high-concentration liquid and the low-concentration liquid by the ion exchange device, so that the running cost can be reduced. .

According to the air conditioner of the seventh aspect, in addition to dehumidification and humidification, for example, oxygen supply to the room can be performed at the same time, so that convenience in use can be improved.
Moreover, since no special device or additional operation is required for such oxygen supply, the device cost and running cost are not significantly increased.
