DETAILED DESCRIPTION OF THE INVENTION

[0001]

This invention relates to lithium chloride (LiCl).
The present invention relates to a liquid passage for flowing a hygroscopic liquid such as a liquid, and a panel using the liquid passage.

[0002]

2. Description of the Related Art Conventionally, as this kind of liquid passage, there is a liquid passage formed of a porous tube, in which a hygroscopic liquid is caused to flow inside the tube, and water vapor is transmitted through a hole of the tube.

[0003]

However, when a large amount of hygroscopic liquid is to flow through the porous tube, it is necessary to increase the diameter of the porous tube. If the diameter is increased, the pressure resistance is increased. Therefore, the thickness of the porous tube must be increased in proportion to the diameter. However, when the thickness of the porous tube is increased, there is a problem that the amount of permeated water vapor decreases. Further, in order to increase the pressure resistance of the porous tube, it is conceivable to make the porous tube by integrating the nonwoven fabric with the porous material. However, in this case, the permeation amount of water vapor also decreases.

[0004] When the flow rate is increased to allow a large amount of hygroscopic liquid to flow while keeping the diameter of the porous tube small, the dynamic pressure applied to the porous tube increases, and as a result, the material of the porous material also increases. It is necessary to increase the film thickness, and there is also a problem that the amount of permeated water vapor is reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a liquid passage which is not damaged even when a large amount of a hygroscopic liquid is allowed to flow, and has a good water vapor permeability.

Another object of the present invention is to allow a large amount of liquid to flow and to cool or heat the liquid in the liquid passage having good water vapor permeability, to be flat and easy to handle. It is to provide a simple panel.

[0007]

According to a first aspect of the present invention, there is provided a liquid passage having a partition wall inside a side wall, a gutter having a comb-like cross section, and a partition wall of the gutter. And a porous film that is attached to the end face and the side wall of the gutter and closes the opening of the gutter.

[0008] The liquid passage according to claim 2 of the present invention,
2. The liquid passage according to claim 1, wherein the gutter is made of a polymer material, and the gutter and the porous film are thermally fused.

Further, the liquid passage according to claim 3 of the present invention,
The liquid passage according to claim 1 or 2, wherein a hydrophobic group is implanted in the porous membrane.

A panel according to a fourth aspect of the present invention is characterized in that a cool storage heat or a heat storage device is provided on the back surface of the gutter of the liquid passage according to any one of the first to third aspects.

[0011]

In the liquid passage of the first aspect, the moisture-absorbing liquid passes through the trough having a comb-like cross section, and the porous film is attached to the end face of the partition wall and the end face of the side wall of the trough. Therefore, the porous membrane has a high pressure resistance and can flow a large amount of the hygroscopic liquid even if the membrane pressure is relatively small. That is, this porous membrane is attached to the end face of the partition wall,
Since it is reinforced, a large pressure resistance can be obtained even with a relatively thin porous membrane. In addition, since the porous membrane is thin, it can sufficiently transmit water vapor, and the water vapor can be absorbed by the hygroscopic liquid passing through the liquid passage, or the water vapor can be released from the hygroscopic liquid. .

According to the liquid passage of the second aspect, the gutter is made of a polymer material, and the gutter and the porous film are heat-sealed, so that the liquid passage can be easily manufactured.

According to the liquid passage of the third aspect, since the porous group is provided with a hydrophobic group, the water vapor does not leak from the porous film in the liquid passage and the water vapor is converted into the liquid. Water vapor can be absorbed or released from the hygroscopic liquid in the liquid passage.

In particular, the gutter is made of a polymer material such as plastic, the porous film is made of, for example, polypropylene, and the plastic and the polypropylene are heat-sealed. Then, hydrophobic groups are implanted in the polypropylene by freon gas or the like. In addition, it is easy and inexpensive to manufacture, and the water vapor permeability can be improved.

According to the panel of the fourth aspect, since the cold storage heat or the heat storage device is provided on the back surface of the gutter of the liquid passage of any one of the first to third aspects, the liquid in the liquid passage is heated or cooled. In addition, the gutter can be formed into a planar shape to improve handling and installation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. In FIG. 1, reference numeral 1 denotes a comb-shaped gutter having a comb-shaped cross section. The gutter includes left and right side walls 1a, 1a and partition walls 1b, 1b,. This gutter is formed from a molded plastic article as an example of a polymer material. A porous film made of, for example, polypropylene is attached to the upper surface of the gutter 1. That is, the porous membrane 2 made of polypropylene is used as the gutter 1 made of plastic.
Are adhered to the upper end surfaces of the side walls 1a, 1a and the upper end surfaces of the partition walls 1b, 1b,. Since polypropylene has low water repellency, in order to improve the water repellency, fluorine is reacted on the surface of the polypropylene after heat fusion to increase the water repellency. That is, a hydrophobic group is planted on the surface of the polypropylene to increase the water repellency. In this way, water vapor is released from the lithium chloride liquid flowing in the gutter 1 or external water vapor is absorbed by the lithium chloride liquid.

Further, a cold storage device 3 in which a cold storage material is sealed is attached to the bottom surface of the gutter 1 so as to cool the lithium chloride liquid flowing in the gutter 1.

The panel using the liquid passage having the above structure is mounted on a ceiling surface or a wall surface, for example, with the porous membrane 2 facing the room. When the lithium chloride liquid flows through the inside of the gutter 1, the external water vapor is absorbed by the liquid lithium liquid through the porous film 2, or the water vapor in the lithium chloride liquid is released to the outside through the porous film 2. The lithium chloride liquid is cooled by the regenerator 3 as needed.

The porous membrane 3 is simply formed on both side walls 1a, 1 of the gutter 1.
Not only is it affixed to the end face of a
Since it is also attached to the upper end surfaces of b and 1b, even if the thickness of the porous film 2 is relatively thin, it has a large pressure resistance. Further, since the porous membrane 2 is provided with a hydrophobic group by reacting fluorine gas with polypropylene, the porous membrane 2 has good water repellency, prevents leakage of the lithium chloride solution from the porous membrane, and has extremely low water vapor permeability. good.

Further, since the porous film 2 is made of polypropylene as a base material, it can be easily heat-sealed to the plastic gutter 1 and the panel can be manufactured at low cost.

Further, in this panel, since the flat regenerative heat storage device 3 enclosing the regenerator is provided on the back of the gutter 1, the lithium chloride liquid flowing in the gutter 1 is efficiently and easily cooled. be able to. Moreover, since this panel is planar, it can be easily attached to a wall surface, a ceiling surface, or the like.

In the above embodiment, the porous film 2 is formed by implanting a hydrophobic group by reacting fluorine with polypropylene. However, the porous film may be formed of PTFE (polytetrafluoroethylene). Needless to say, the gutter can be made of a material such as PTFE without being limited to plastic. Further, in the above-described embodiment, the cold storage heat device is used on the back surface of the gutter 1, but a heat storage device in which a heat storage material is sealed may be provided.
