Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air humidity control device utilizing the heat of reaction during hydrogen storage and release of a hydrogen storage alloy,
The present invention relates to an air conditioner, a dehumidifying / drying machine, a dehumidifying machine, and a method therefor.

[0002]

2. Description of the Related Art Conventionally, as a dehumidifier using a hydrogen storage alloy, there is a dehumidifier mounted on a vehicle or the like. This is to dehumidify without using engine power by utilizing engine exhaust heat. That is, as a dehumidifying method of such a dehumidifier, as shown in FIG. 4, first, hydrogen is absorbed in the hydrogen storage alloy 11 in the initial state, and the hydrogen storage alloy 12 is It is in a hydrogen dissociation state. And these two kinds of hydrogen storage alloys 11, 12
Are different hydrogen storage alloys showing different pressures under the same temperature condition.

When the valve 15 is opened in this state, the hydrogen gas is forced into the hydrogen storage alloy 1 in the first container 13 due to the pressure difference.
It moves from 1 to the hydrogen storage alloy 12 in the second container 14. At this time, the hydrogen storage alloy 11 undergoes an endothermic reaction, so that the surface temperature of the first container 13 decreases and dew condensation occurs. That is, the air around the first container 13 is dehumidified.

On the other hand, since the hydrogen storage alloy 12 causes an exothermic reaction, when dehumidifying, the cooled air is simultaneously sent to the container 14, and the heat generated is used to restore the dehumidified air to the original temperature.

After that, the pressure difference disappeared and hydrogen was replaced by alloy 12
When it has completely moved to, the above reaction stops.

Once the reaction is stopped, the dehumidifying operation is also stopped. Therefore, in order to restart this dehumidifying operation, it is necessary to return to the initial state again.

Therefore, in this case, the valve 15 is closed to supply the engine exhaust heat to the container 14 and the outside air to the container 13. As a result, the hydrogen storage alloy 1 inside the container 14
As the temperature of 2 rises above the above exothermic reaction temperature, the pressure inside the container 14 rises and becomes higher than the pressure inside the container 13.

When the valve 15 is opened from such a state, hydrogen is moved from the alloy 12 to the alloy 11 this time and returns to the initial state again due to the above-mentioned high / low pressure difference. Thus, naturally, the dehumidification operation cannot be performed while returning to the initial state again.

By repeating these series of operations,
The dehumidifying operation is performed intermittently.

[0010]

However, in such a conventional method, there is a problem that exhaust heat from the engine or the like is indispensable for returning to the initial state, and that it is a batch type and only intermittent operation is possible.

Therefore, it is very difficult to dehumidify the room of a general household and to apply it to a clothes dryer.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the concept of an air humidity adjusting apparatus as a first embodiment of the present invention, and the configuration of this embodiment will be described with reference to the same figure.

In the figure, the hydrogen having a pressure of 10 kgf / cm ² G flows through the high-pressure pipeline 1a, and the hydrogen having a pressure of 1 kgf / cm ² G flows through the low-pressure pipeline 1b. These hydrogen pipelines 1a and b are three-way cocks 2 respectively.
The heat exchangers 4a and 4b containing the hydrogen storage alloys 3a and 3b are connected via a and b. The heat exchangers 4a and 4b are placed in the air flow paths 6a and 6b, respectively. Air flow path 6
Fans 6a and b are built in a and b as air moving mechanisms. Here, the high-pressure pipeline 1a corresponds to the high-pressure system having high-pressure hydrogen of the present invention, and the low-pressure pipeline 1b corresponds to the low-pressure system having low-pressure hydrogen of the present invention. The three-way cock 2a is the first opening / closing means of the present invention.
The three-way cock 2b corresponds to the second opening / closing means of the present invention.

As the hydrogen storage alloys 3a and 3b, Ti _0.7 Zr _{0.3 is used.}
Mn _1.8 Cr _0.2 is used. This alloy gives off the heat of hydrogenation at 45 ° C. when it absorbs hydrogen at 10 kgf / cm ² G. It also releases hydrogen at 1 kgf / cm ² G and outputs 5 ° C cold heat.

There are various types of hydrogen storage alloys, and alloys that substantially satisfy the above conditions, such as misch metal-nickel alloys, may be used. The hydrogen storage alloys 3a and 3b may be different types of hydrogen storage alloys.

An example of the dehumidifying method of the present invention will be described at the same time as the operation of the present embodiment having the above-mentioned structure is described.

That is, in the initial state, hydrogen is stored in the hydrogen storage alloy 3a, and hydrogen is released in the hydrogen storage alloy 3b. The three-way cock 2a is a heat exchanger 4a
Side, and the three-way cock 2b is open to the heat exchanger 4b side. Therefore, the hydrogen pressure in the heat exchanger 4a is 10 kgf /
cm ² G, and the hydrogen pressure in the heat exchanger 4b is 1 kgf / cm ² G.

Next, the three-way cock 2a is opened to the heat exchanger 4b side, and the three-way cock 2b is opened to the heat exchanger 4a side almost at the same time. Then, the hydrogen pressure in the heat exchanger 4a instantly becomes 1 kgf / cm ² G, and the hydrogen pressure in the heat exchanger 4b becomes 10 kg.
It becomes f / cm ² G. Hydrogen storage alloy 3a releases hydrogen and is 5 ° C.
Outputs the cold heat of. The air in the air flow path 5a is cooled and dehumidified by this cold heat and moved by the fan 6a. On the other hand, the hydrogen storage alloy 3b stores hydrogen and releases heat of hydrogenation at 45 ° C. This heat heats the air in the air flow path 5b and moves it by the fan 6b.

When this reaction is completed, the three-way cock 2 is restarted.
a is opened to the heat exchanger 4a side, and the three-way cock 2b is opened to the heat exchanger 4b side. Then, again, the hydrogen pressure in the heat exchanger 4a becomes 10 kgf / cm ² G, and the hydrogen pressure in the heat exchanger 4b becomes 1 kgf / cm ² G. Therefore, contrary to the above, the hydrogen storage alloy 3a stores hydrogen and releases heat of hydrogenation at 45 ° C. Further, the hydrogen storage alloy 3b releases hydrogen and outputs cold heat of 5 ° C. As a result, this time, the air in the air flow path 5a is heated and moved by the fan 6a, and the air flow path 5b is moved.

Next, the second embodiment of the present invention will be described in detail.

FIG. 2 is a conceptual diagram of the dehumidifier of the second embodiment of the present invention. The same reference numerals as those in FIG. 1 indicate objects having the same function.

In FIG. 2, the air flow paths 5a and 5b, which are independent from each other in FIG. 1, are connected to each other by an air flow path 5c. In addition, the air flow paths 5a and 5b are provided with outside air introduction and discharge ports 7a and 7b.

Next, the operation of this embodiment having the above configuration will be described.

That is, in the initial state, as in the first embodiment, hydrogen is stored in the hydrogen storage alloy 3a and hydrogen is released in the hydrogen storage alloy 3b. The three-way cock 2a is open to the heat exchanger 4a side, and the three-way cock 2b is open to the heat exchanger 4b side. Therefore, the heat exchanger 4a
The hydrogen pressure inside is 10 kgf / cm ² G, and the hydrogen pressure inside the heat exchanger 4b is 1 kgf / cm ² G.

Next, the three-way cock 2a is opened to the heat exchanger 4b side, and the three-way cock 2b is opened to the heat exchanger 4a side almost at the same time. Then, the hydrogen pressure in the heat exchanger 4a instantly becomes 1 kgf / cm ² G, and the hydrogen pressure in the heat exchanger 4b becomes 10 kg.
It becomes f / cm ² G. Hydrogen storage alloy 3a releases hydrogen and is 5 ° C.
Outputs the cold heat of. Outside air introduction / exhaust port 7 in air passage 5a

On the other hand, the hydrogen storage alloy 3b stores hydrogen and releases heat of hydrogenation at 45 ° C. This heat heats the air in the air flow path 5b, returns the temperature to almost the outside temperature, and discharges the outside air from the outside air introduction / exhaust port 7b.

When this reaction is completed, the three-way cock 2 is restarted.
a is opened to the heat exchanger 4a side, and the three-way cock 2b is opened to the heat exchanger 4b side. Then, again, the hydrogen pressure in the heat exchanger 4a becomes 10 kgf / cm ² G, and the hydrogen pressure in the heat exchanger 4b becomes 1 kgf / cm ² G. Therefore, contrary to the above, the hydrogen storage alloy 3a stores hydrogen and releases heat of hydrogenation at 45 ° C. In addition, the hydrogen storage alloy 3b releases hydrogen and is at 5 ° C.
Outputs the cold heat of. At this time, all fans 6
By reversing a, b, and c, the outside air is introduced into the air passage 5b through the outside air introduction / exhaust port 7b to perform cooling and dehumidification. This cooled and dehumidified air is supplied to the air flow path 5 by the fan 6c in the air flow path 5c.
Move to a. The air in the air flow path 5a is heated to approximately the ambient temperature, and is discharged from the outside air introduction / exhaust port 7a to the outside air. The time when this reaction ends is the same as the initial state.

Therefore, by repeating the above-described series of operations, it is possible to continuously dehumidify the room without supplying heat from the outside.

In this embodiment, the air passages are switched by reversing the fan, but individual air passages may be formed and switched by valves or the like. Also, at this time, if the heat exchange efficiency on the cooling / dehumidifying side is reduced and the heating of the air is made relatively strong, it can be applied to heating, and conversely, the heat exchange efficiency of the air heating is reduced and cooling is relatively performed. If strengthened, it can be applied to air conditioning. Therefore, according to such a configuration, cooling, heating, or dehumidifying operation can be performed as the air conditioner.

Next, the third embodiment of the present invention will be described in detail.

FIG. 3 is a conceptual diagram of a dryer according to the third embodiment of the present invention. The same reference numerals as those in FIGS. 1 and 2 indicate objects having the same function.

In FIG. 3, the air flow paths 5a and 5b, which are opened to the outside air by the outside air introduction and discharge ports 7a and 7b in FIG. 2, are connected to the drying chamber 8 to form an air circulation path 9.

Next, the operation of the present embodiment having the above configuration will be described.

That is, in the initial state, as in the first embodiment, hydrogen is stored in the hydrogen storage alloy 3a, and hydrogen is released in the hydrogen storage alloy 3b. The three-way cock 2a is open to the heat exchanger 4a side, and the three-way cock 2b is open to the heat exchanger 4b side. Therefore, the heat exchanger 4a
The hydrogen pressure inside is 10 kgf / cm ² G, and the hydrogen pressure inside the heat exchanger 4b is 1 kgf / cm ² G.

Next, the three-way cock 2a is opened to the heat exchanger 4b side, and the three-way cock 2b is opened to the heat exchanger 4a side almost at the same time. Then, the hydrogen pressure in the heat exchanger 4a instantly becomes 1 kgf / cm ² G, and the hydrogen pressure in the heat exchanger 4b becomes 10 kg.
It becomes f / cm ² G. Hydrogen storage alloy 3b absorbs hydrogen,
The heat of hydrogenation is released at 0 ° C, while the hydrogen storage alloy 3a releases hydrogen and outputs cold heat of 5 ° C. First, the air in the air flow path 5b is heated by the heat of hydrogenation at 45 ° C. The hot air is sent to the drying chamber 8 by the fan 6b. In the drying chamber 8, for example, water such as clothes is removed. The high-temperature and high-humidity air is introduced into the air flow path 5a, and is cooled and dehumidified by cold heat of 5 ° C. The cooled and dehumidified air is moved to the air flow path 5b by the fan 6c in the air flow path 5c and circulated.

When this reaction is completed, the three-way cock 2 is restarted.
a is opened to the heat exchanger 4a side, and the three-way cock 2b is opened to the heat exchanger 4b side. Then, again, the hydrogen pressure in the heat exchanger 4a becomes 10 kgf / cm ² G, and the hydrogen pressure in the heat exchanger 4b becomes 1 kgf / cm ² G. Therefore, contrary to the above, the hydrogen storage alloy 3a stores hydrogen and releases heat of hydrogenation at 45 ° C. In addition, the hydrogen storage alloy 3b releases hydrogen and is at 5 ° C.
Outputs the cold heat of. At this time, all fans 6
By reversing a, b, and c, the air in the air passage 5a is heated and sent to the drying chamber 8, and the humid air that has absorbed moisture such as clothes is cooled and dehumidified in the air passage 5b. The cooled and dehumidified air is moved to the air flow path 5a by the fan 6c in the air flow path 5c and circulated. The time when this reaction ends is the same as the initial state.

Therefore, by repeating the above-mentioned series of operations, clothes and the like can be continuously dried without supplying heat from the outside.

In this embodiment, the air passages are switched by reversing the fan, but individual air passages may be formed and switched by valves or the like. In addition, it can be used not only for clothing but also for drying food, wood, etc.

In the above embodiment, the case where two hydrogen storage alloys are used has been described, but the present invention is not limited to this, and one hydrogen storage alloy may be used.

That is, in this case, one hydrogen storage alloy,
A heat exchange means for incorporating the hydrogen storage alloy therein to exchange heat with air, a first opening / closing means for controlling communication between the high pressure system having high pressure hydrogen and the heat exchange means, and a pressure lower than the high pressure hydrogen. A second opening / closing means for controlling communication between the low-pressure system containing hydrogen and the heat exchange means, and the first and second
By controlling the opening / closing of the opening / closing means, the exothermic reaction when the hydrogen storage alloy stores the high-pressure hydrogen and / or the endothermic reaction when the stored hydrogen is released to the low-pressure system is used, By adopting a structure that adjusts the humidity inside, the humidity can be adjusted without supplying heat from the outside, although it is intermittent.

In addition, the air-humidity adjusting device having such a structure needs only one expensive hydrogen storage alloy, and therefore the structure can be simplified and the overall cost can be reduced as compared with the conventional one. Such an effect is exhibited.

In the above embodiment, the case where the high pressure system of the present invention is a high pressure pipeline and the low pressure system of the present invention is a low pressure pipeline has been described, but the present invention is not limited to this. Of course, the case of using a low-pressure hydrogen storage device or the like as the latter is also acceptable.

In the above embodiment, the case where the high pressure system and the low pressure system of the present invention maintain constant pressures is described, but the present invention is not limited to this. For example, the hydrogen pressure of the low pressure system is higher than that of the high pressure system. It does not matter whether or not each system maintains a constant pressure as long as it maintains a relative pressure relationship of being lower than the pressure.

That is, specifically, dehumidification can be continuously performed without exhaust heat of the engine or the like or heating by a heater or the like.
Further, it is possible to easily provide an indoor dehumidifier and a dryer.
