BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a heat storage body in a space between an outer wall body and an inner wall body, and an intake port capable of taking a contact fluid into the space and a discharge port capable of discharging the contact fluid into the room. The present invention relates to a stretchable heat storage capsule used in a heat storage wall structure provided with a fan therefor and a method of using the same.

[0002]

2. Description of the Related Art Conventionally, in the heat storage wall structure as shown in FIG. 6, the intake 20 and the discharge port 21 are formed in the inner wall 2 facing the room, and the heat storage 3 is the inner wall. It was installed in the space D between the outer wall body 1 and the inner wall body 2 when forming 2, and after the inner wall body 2 was attached, it was not possible to put it in and out of the space D. However, according to such a heat storage wall structure, for example, when it is necessary to take out the heat storage body from the space for maintenance inspection or replacement of the heat storage body, the inner wall body must first be removed, and After re-storing the heat storage body in the space, it is necessary to perform work such as re-installing the inner wall body again, and there is a problem that it takes much time to take the heat storage body in and out of the heat storage wall.

As a method of solving such a problem, an opening having a size that allows the heat storage body 3 to be taken in and out is provided in the inner wall body 2, and after the inner wall body 2 is attached, the inner wall lid is opened and closed to open the heat storage body. A method that makes it possible to take out is conceivable.

[0004]

However, it is a design problem to attach a lid to the inner wall by forming a large opening in the inner wall because it impairs the aesthetics, and it is necessary to open and close the heat storage body while ensuring operability. It was a requirement of the industry to keep the department as small as possible.

Therefore, an object of the present invention is to solve the above-mentioned problems and to secure the operability of taking in and out the heat storage body from the heat storage wall, and at the same time, to provide a stretchable heat storage capsule capable of making the opening as small as possible and a method of using the same. To provide.

[0006]

The elastic heat storage capsule of the present invention for attaining the above object is characterized in that a plurality of sheet portions are supported at both ends between the plurality of sheet portions.
And a bag portion that is expandable so as to increase the thickness between the sheet portions while maintaining the flow path of the contact fluid with the introduction of the heat storage material,
And an openable and closable communication part that can communicate with the bag part.

In the above structure, it is not necessary that all of the bag portions communicate with each other, and a plurality of independent communication portions may be provided for each. Further, as a method of forming the bag portion so as to be expandable and contractible, the shape may be mainly devised such as a bellows shape, or the material may be devised mainly by using an elastic body. However, it is preferable that all the bag portions are in communication with each other, and that the bag portions are formed in a bellows shape so as to be expandable and contractible in order to achieve the operational effects described later. The bellows-like shape means a shape that can be expanded and contracted according to the degree of bending by a curved surface having a plurality of bent portions.

The characteristic configuration of the method of using the stretchable heat storage capsule of the present invention is that a heat storage body capable of storing and radiating heat by heat exchange with a contact fluid is provided in the space between the outer wall body and the inner wall body, and An inlet for freely introducing the contact fluid into a space, an outlet for freely discharging the contact fluid brought into contact with the heat storage body into the space into the chamber, and the contact fluid from the inlet to the space. A method of using the above-described stretchable heat storage capsule in a heat storage wall structure provided with a fan for sucking in and discharging from the discharge port, wherein the stretchable heat storage capsule is degassed in the bag portion. By introducing the heat storage material into the space and introducing the heat storage material through the communication portion, the sheet portion existing on the front and back surfaces is brought into pressure contact with the wall surface of the space to close the communication portion.

[Advantageous Effects] According to the stretchable heat storage capsule of the present invention, the plurality of sheet portions are supported at both ends between the plurality of sheet portions, and the thickness between the sheet portions is increased with the introduction of the heat storage material. Since it has a flexible bag part so as to increase the thickness, the thickness between the sheet parts is increased by introducing the heat storage material,
The sheet portion existing on the front and back surfaces is pressed against the side wall of the space inside the heat storage wall, and the heat storage capsule is held in the space inside the heat storage wall by the frictional force between the sheet portion and the side wall. Then, since the bag portion swells while maintaining the flow path of the contact fluid, the contact fluid can be circulated in the retained state to store and radiate heat. Furthermore, since the bag includes a communication part that can be opened and closed so that it can communicate with the bag part, it is possible to hold the heat storage material inside the heat storage capsule after opening the part and performing the introduction operation described above. it can. On the other hand, when the heat storage material is not introduced, since the bag portion is contracted and the thickness between the sheet portions is small, the heat storage capsule can be easily put in and taken out from the space inside the heat storage wall through the narrow gap having the width of the sheet portion. it can. As a result, it was possible to provide a heat storage capsule in which the opening can be made as small as possible while ensuring the operability of taking in and out the heat storage body from the heat storage wall.

In addition, when all the bag portions are in communication with each other and are formed in a bellows shape so that they can be expanded and contracted, all the bag portions are in communication, so that if the heat storage material is introduced from one place, it is introduced into the entire heat storage capsule. The heat storage material can be easily taken in and out. In addition, since it is formed in a bellows shape and can be expanded and contracted, the contact area of the contact fluid can be increased, and it is possible to expand and contract in the thickness direction without being greatly affected by the elastic force of the material during expansion and contraction, and the distance between walls Even if it is different, it can be widely supported.

On the other hand, according to the method of using the stretchable heat storage capsule of the present invention, since the stretchable heat storage capsule is introduced into the space while the bag portion is degassed, the bag portion shrinks ( Since the thickness between the sheet portions is small, the heat storage capsules can be easily introduced into the space inside the heat storage wall through the narrow gap having the width of the sheet portions. Further, by introducing the heat storage material through the communication portion,
In order to bring the sheet portion existing on the front and back surfaces into pressure contact with the wall surface of the space, the thickness between the sheet portions is increased by the introduction of the heat storage material, and the sheet portion existing on the front and back surfaces comes into pressure contact with the side wall of the space inside the heat storage wall. The heat storage capsule is held in the space inside the heat storage wall by the frictional force between the seat portion and the side wall. The heat storage material can be held inside the heat storage capsule by closing the communication portion. As a result, it was possible to provide a method of using the heat storage capsule in which the opening can be made as small as possible while ensuring the operability of taking the heat storage body in and out of the heat storage wall.

Such an elongated bag portion 22a can be formed by bending the bellows portion by heating or the like. The bag communicating portion 22b is formed in a flat tubular shape below the bellows portion in the vertical direction so that the mountain portions of the bellows communicate with each other. Then, the bag portion 22 increases the thickness between the sheet portions 21 with the introduction of the heat storage material 9, but at this time, the bellows portion is unlikely to spread in the lateral direction, and can be expanded and contracted while maintaining the flow path S of the contact fluid. There is.

On the other hand, the communication portion 23 has an openable / closable valve 23a for communicating with the bag portion 22, but may be constructed to be openable / closable by a bolt or the like. In FIG. 2, the communication portion 23 is connected to the seat portion 21 almost vertically,
If that portion interferes with the inner wall, it is preferable to connect from below the bag portion 22.

It is not limited to calcium chloride hexahydrate (CaCl ₂ .6H ₂ O), but for example sodium sulfate decahydrate (NaS
O ₄ · 10H ₂ O), or other latent heat storage materials that undergo a phase change near room temperature can be used, and they are collectively referred to as heat storage materials.

On the other hand, the method of using the stretchable heat storage capsule of the present invention stores and radiates heat by exchanging heat with the contact fluid R in the space D between the outer wall 1 and the inner wall 2 as shown in FIG. A free heat storage body 3 is provided, and an intake port 4 that can take in the contact fluid R from the room to the space D and a discharge port 5 that can freely discharge the contact fluid R taken into the space D and brought into contact with the heat storage body 3 into the room And a fan F for sucking the contact fluid R into the space D from the inlet 4 and discharging the contact fluid R from the outlet 5 are applied to the heat storage wall structure.

First, the outline of the heat storage wall structure will be described. In this embodiment, a heat storage unit T is installed inside a wall W of a building, and the indoor temperature can be controlled by heat exchange in the heat storage unit T. Has been formed. However, the heat storage wall structure is not limited to this, and for example,
The heat storage body 3 may be housed directly in the space D.

The heat-insulating outer wall body 1 has a general heat-insulating effect in addition to a general function as an outer wall. After the heat-insulating outer wall body 1 is installed, the heat storage unit T is arranged along the inside of the heat-insulating outer wall body 1. The inner wall 2 is installed on the indoor side to secure an indoor space. At the upper end portion and the lower end portion of the inner wall body 2, openings 2a through which the air R can freely flow are separately provided at portions facing an intake port 4 and a discharge port 5 provided in the heat storage unit T, which will be described later. The opening 2a on the lower side is arranged in the skirting part h in the room. Here, the intake port 4 and the discharge port 5 in the wall body
3 shows that the intake port 4 is arranged at the upper end and the discharge port 5 is arranged at the lower end in FIG. 3, but in addition to that, the discharge port is arranged at the upper end and the intake port is arranged at the lower end. The inlet and the outlet may be arranged separately on the left and right.

The heat storage unit T makes it possible to introduce a stretchable heat storage capsule C into the space D, and an intake port 4 into which the air R can be taken in freely and the taken air R to the outside. It has a free discharge port 5. Further, a plurality of dampers 7 that can open and close the intake port 4 and the discharge port 5, respectively, and a fan F for sucking the air R from the intake port 4 into the inner space and discharging the air R from the discharge port 5 are provided. However, by switching the rotation direction (air blowing direction) of the fan F, the upper end portion becomes the discharge port,
The lower end may be used as the inlet, and the fan F may be provided at the middle or lower end of the unit container 6 instead of being provided at the upper end of the unit container 6.

Discharge port 5 for introducing elastic heat storage capsule C
Is formed at a portion corresponding to the skirting board portion h of the other wall portion, and is inconspicuous in the indoor landscape, and has an effect of preventing deterioration of aesthetics. On the other hand, the upper and lower ends of the unit container 6 are separately connected with communication pipes 8 that can be switched between a communication state in which the inner space of the unit container 6 communicates with the outdoor space and a shut-off state in which the unit container 6 is shut off. .

Then, the method of using the stretchable heat storage capsule C of the present invention for the above heat storage wall structure is to introduce the stretchable heat storage capsule C into the space D in a state where the bag portion 22 is degassed. By introducing the heat storage material 9 through 23,

At this time, it is preferable that the bag 22 be degassed to be as thin as possible, but it is not necessary to completely degas the bag portion 22. In this state, the stretchable heat storage capsule C is introduced into the space D of the heat storage unit T through the opening 2a from which the lower damper 7 is removed, and the stretchable heat storage capsule C is supported by, for example, the support portion 6a. At this time, a flat plate or the like having a plurality of slits that can be opened and closed may be used as the support portion 6a.

In the above, the heat storage material 9 is introduced into the stretchable heat storage capsule C via the communication portion 23 using the liquid supply pump 24 and the like. The introduction is performed until almost the entire sheet portion 21a existing on the front and back surfaces comes into pressure contact with the wall surface of the space D.

In the above, with the elastic heat storage capsule C held in the space D by pressure contact, the communication part 23 is closed by closing the valve. After that, the joint 23b is removed to remove the liquid supply pump 24 and the like, and the lower damper 7 is attached to the original position.

When the elastic heat storage capsule C is taken out,
The above operations may be performed in the reverse order. That is, the communication part 23
The heat storage material 9 may be discharged through the communication part 23 and the contracted elastic heat storage capsule C may be taken out from the space D.

An example of the room temperature control by the heat storage wall will be explained. As shown in FIG. 4, by opening each damper 7 and driving the fan F in the daytime with the communication pipe 8 closed, the room F The excess heat of 1 is stored in the heat storage material 9, and the room temperature lowering effect is exerted in the hot season, and the stored heat can be released at night in the cold season to exert the room temperature increasing effect. However, regarding the use in the hot season, as shown in FIG. 4B, at night, by driving the fan F with the discharge port 5 closed and the communication pipe 8 opened, the accumulated heat is externally discharged. It is possible to dissipate heat and prepare for heat storage the next day.

The present invention can be applied to walls of various structures such as general houses, factory equipment, office buildings, and the like.
