Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for cooling and heating an internal space of a building such as a house through a floor surface or a ceiling surface, and particularly to a bag-like container filled with water or a similar liquid. It relates to a cooling and heating structure.

[0002]

2. Description of the Related Art The inventors of the present invention have proposed a structure in which a bag-like container filled with water or a similar liquid is disposed below a floor of a structure such as a house or the like, and the indoor space is cooled or heated through the floor. (Japanese Patent Application Nos. 5-135178 and 5-19983)
No. 10-42981). This cooling and heating structure has the following basic configuration.

That is, in FIGS. 10 and 11, bag-shaped water containers 1 are respectively arranged in spaces formed below the floor of a structure (house) by a partition member 52 called a joist. . These water containers 1 include, for example, an electric heater EH
And other heat sources. Electric heater EH during heating
Heat from a heat source such as is transmitted to the water container 1, the water W in the water container 1 circulates and flows by this heat, and the entire water container 1 is uniformly heated, and this heat is transmitted to the room through the floor surface. Is done. In addition, cooling can be performed in summer by arranging, for example, a pipe through which cold water passes outside the heat source for heating.

[0004] In the floor cooling and heating structure having the above-described structure, the entire water container 1 is uniformly heated or cooled by the circulating flow of the filled water W. Therefore, neither the heating heat source nor the cooling heat source is provided to the water container 1. And can be formed small. In addition, since the medium is water with a large specific heat, it is possible to stably cool and heat the room without frequently adjusting the temperature of the heat source. As a result, it is possible to provide a cooling and heating structure that is more excellent in both cooling and heating efficiency and economy.

[0005]

The cooling and heating structure using the water container 1 has many advantages as described above. When not used, the water W in the water container 1 may freeze. Since the material constituting the water container 1 has a strong structure in which various films are laminated, there is no problem in the physical strength of the water container, but it copes with an increase in volume due to freezing of the filled water. There is a need to.

As a means for coping with this increase in volume, as shown in FIG. 10, when the water is filled, a bent portion 1a is formed on the upper portion of the water container 1 in the space where the water container 1 is stored. The water container is formed in advance in such a size as to be used. When the bent portion 1a is formed in this manner, the increase in volume caused by the freezing of the water W inside the water container is absorbed by the space formed by the bent portion 1a, thereby coping with the increase in volume to some extent. It becomes possible.

However, setting the bent portion large is not preferable because it reduces the contact area of the water container 1 with the floor 51. Further, even if the size of the water container 1 is increased to increase the space formed by the bent portion 1a, the bent portion comes into contact due to the water pressure, and the size of the space formed by the formation of the bent portion 1a is reduced. There is a limit. Further, the formation of the bent portion 1a depends not only on the size of the water container 1 but also on the amount of water injected into the water container 1. However, since the water injection is performed before the floor is put on the building site, an appropriate It is difficult to delicately adjust the amount of water to be bent. If the amount of injected water is too large and the bent portion 1a is hardly formed, problems such as deformation of the floor surface may occur due to the increased volume due to freezing of the water W.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been made in consideration of the volume of water formed by freezing of water in a space in which a water container is stored or directly in the water container. A cooling and heating structure using a water container, characterized in that a means for securing a space for absorbing the increase in water is provided.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A deformable member such as a sponge-like member, a spring material, or a corrugated plate-like member is arranged between a space for accommodating a water container and the water container to increase the volume due to freezing of water. Is absorbed by deformation of these members.
Further, the deformable member may be arranged in a water container and configured to deform in the water container.

When the water in the water container freezes, the deformable member is deformed by an amount corresponding to the increase in volume due to the freezing, and a space for absorbing the increase in volume is eventually secured. Conversely, when ice melting begins in the water container, the deformed member returns to its original state by the reduced volume,
For example, a problem such as separation of the water container from the back surface of the floor due to a decrease in the volume of the whole water container does not occur.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In the figure, a sponge-like flexible material is disposed as a deformable material 3 between a water container 1 and a floor lower support portion 2. When the water W in the water container 1 freezes and the volume increases, the increased amount is absorbed by the deformation of the flexible material 3. Further, since the deformable material 3 is formed to be porous, it is possible to exhibit extremely high heat insulating properties. Therefore, the heat in the water container 1 is wastefully radiated through the floor lower support portion 2. It can also be used as a heat insulating material to prevent the occurrence.

Also, in the configuration shown in FIG.
a is formed, but the increase in volume due to freezing is absorbed only by the deformation of the deformable material 3, and the bent portion 1a is formed in a size that allows the water container 1 itself to cope with the increase in volume. Therefore, the bent portion may be made large as indicated by reference numeral 1a '. Note that the illustrated water container 1 shows a cross section of a portion where a heating element such as an electric heater is not installed so that the connection relationship with the deformable material can be clearly understood. Hereinafter, the same applies to each embodiment.

FIG. 2 shows a second embodiment. In this embodiment, a corrugated sheet is used as the deformable member 4 and both sides of the water container 1 and the partition member 5.
2 are respectively arranged. In this configuration, the deformation of the water container 1 due to freezing is performed on both sides of the water container 1,
When the wave shape of the deformable member 4 is deformed, a space corresponding to the expansion of the water container 1 is secured. Although not shown, the deformable member 4 may be disposed between the floor lower support member 2 and the water container 1 as in the case of the flexible material. You may make it use together.

FIG. 3 shows a third embodiment. In the figure, reference numeral 5 denotes a deformable material, which is formed of a sponge-like porous material such as the flexible material 3 shown in FIG. The deformable member 5 is formed, for example, in a tubular shape located in the longitudinal direction of the water container 1, or is formed as a plurality of independent masses. The deformable material 5 is composed of the floor lower support 2 and the water container
Since the water container 1 is disposed between the deformable member 5 and the water container 1, the deformable member 5 forms the bent portion 1 b along the outer shape of the deformable member in the deformable member disposing portion.

The increase in volume due to the freezing of the water W is absorbed by the deformable material 5 contracting and deforming through the bent portion 1b. That is, since the bent portion 1b in the water container 1 serves as a margin for absorbing the increase in the internal volume, in this embodiment, it is not necessary to separately form the bent portion 1a as in each of the above embodiments. The entire upper surface can be configured to be in close contact with the floor plate 51.

FIG. 4 shows a fourth embodiment. Reference numeral 6 denotes a deformable material, which is arranged in the water container 1 unlike the third embodiment. Reference numeral 6A in FIG. 5 shows the structure of the deformable material 6. The deformable member 6 formed in a cylindrical shape or a plurality of balls is housed in the water container 1. The deformable member 6 includes a sponge-like porous deformed portion 6a and a waterproof coating 6b covering the entire deformed portion 6a.

The increase in volume due to freezing is absorbed by the deformable material contracting and deforming as indicated by reference numeral 6B in accordance with the increase in volume. By the way, when the waterproof film 6a is not provided, the water has penetrated into the deformed portion itself, so that the function of absorbing the volume expansion does not occur. In this embodiment, a space for absorbing volume expansion is secured in the water container 1 by disposing the deformed portion in the water W. For this reason, the surface area of the water container 1 does not increase due to the expansion of the volume, and therefore it is not necessary to form the bent portion 1a in the water container 1 as in the third embodiment.

FIG. 6 shows a fifth embodiment. In this embodiment, the space formed by reducing the amount of water injected into the water container 1 is used as a space allowing expansion of the volume, which is a more simplified version of the fourth embodiment of FIG. It can be said that. Reference numeral 7 denotes a space formed above the water W in the water container 1. In this embodiment, heat transfer to the floor 51 is performed indirectly via the space 7 in the water container 1. That is, steam vaporized from the water W condenses on the upper portion of the water container that is in close contact with the floor 51, and releases latent heat. In other words, the heat can be efficiently supplied to the floor 51 by releasing the latent heat by the steam circulating between the water W and the upper part of the water container. The increase in volume due to the freezing of the water W is absorbed by the space 7.

FIG. 7 shows a sixth embodiment, in which a deformable material is arranged on at least one of the two longitudinal ends of the water container 1 to secure a space for volume expansion. First, in FIG. 8A, corrugated deformation members 8 are arranged between both side edges of the end of the water container 1 and the partition member 52, respectively. The expansion of the volume of the entire water container due to freezing is concentrated at the end of the water container 1, and the deformable material 8 deforms in response to the expansion, thereby allowing the entire volume of the water container 1 to expand. Incidentally, the water in the water container 1 does not freeze instantaneously, and a frozen portion is formed in the water W in response to a decrease in the ambient temperature.
Until the water inside is completely frozen, a sherbet-like flow state is secured, so that the expansion of the volume of the entire water container concentrates on the space where the deformable material 8 is arranged by the flow of the internal fluid. become.

FIG. 2B uses a leaf spring bent in a hairpin shape as a deformable material (indicated by reference numeral 9). In the configuration using the deformable material 9, the expansion of the water container 1 is allowed by the deformable material 9, which is a hairpin-shaped leaf spring, being bent and deformed in the closing direction by the expansion of the volume of the water container 1.

FIG. 8 shows a seventh embodiment. This embodiment is a modification of the configuration shown in FIG. 7B, in which a hairpin-shaped leaf spring (indicated by reference numeral 10) is provided between the end of the water container 1 and the floor lower support 2 as a deformable material. It is interposed. The expansion of the volume of the water container 1 is allowed by the side of the hairpin-shaped leaf spring 10 supporting the end of the water container 1 being bent down to the floor lower support portion 2 side. . In this embodiment, the entire upper surface of the end of the water container 1 is
Can be adhered to. Therefore, by disposing the deformable members 8 and 9 as shown in FIG. 7, the space does not become a non-contact space between the water container 1 and the floor 51, and the heat transfer efficiency can be increased accordingly.

FIG. 9 shows an eighth embodiment. This embodiment is also a modification of the cross example shown in FIGS. 7B and 8.
In the figure, a leaf spring (indicated by reference numeral 11) whose side surface shape is bent into a hairpin shape as a deformable material is interposed between at least a part of the longitudinal side edge of the water container 1 and the partition member 52. . The expansion of the volume of the water container 1 is configured such that the side of the leaf spring 11 that supports the side edge of the water container 1 is allowed to bend toward the partition member 52. Also in the configuration of this embodiment, the entire upper surface of the water container 1 can be in close contact with the floor portion 51 as in the case of the seventh embodiment.
