Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for cooling and heating an internal space via a floor surface or a ceiling surface of a building structure such as a house, and more particularly to a cooling and heating structure using a bag-like container filled with water or a liquid similar thereto.
[0002]
[Prior art]
The inventors have proposed a structure in which a bag-like container filled with water or a liquid similar thereto is arranged at the lower part of the floor of a structure such as a house and the indoor space is cooled and heated via the floor (special feature). Nos. 5-135178, 5-19983, 8-271357, and 10-42981). This air conditioning structure has the following basic configuration.
[0003]
That is, in FIGS. 10 and 11, the bag-shaped water containers 1 are respectively arranged in spaces having a certain volume formed by the partition material 52 called joists at the lower part of the floor surface of the structure (house). ing. These water containers 1 are provided with a heat source such as an electric heater EH. During heating, heat from a heat source such as the electric heater EH is transmitted to the water container 1, and the water W in the water container 1 is circulated and flowed by this heat to uniformly heat the entire water container 1, and this heat is applied to the floor surface. Via the room. In addition, it is possible to perform cooling in the summer by arranging, for example, a pipe through which cold water passes outside the heat source for heating.
[0004]
In the floor cooling / heating structure with the above configuration, the entire water container 1 is uniformly heated or cooled by the circulating flow of the filled water W, so that either the heating heat source or the cooling heat source is smaller than the water container 1. Can be formed. 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. Compared to the above, it is possible to provide an air conditioning structure that is superior in both efficiency and economic efficiency.
[0005]
[Problems to be solved by the invention]
The air-conditioning structure using the water container 1 has many advantages as described above. For example, when the device is not used for a long period of time, such as by leaving the house for a relatively long time in winter, The water W 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 as the water container, but the increase in volume due to freezing of the filled water is dealt with. There is a need to.
[0006]
As shown in FIG. 11 , the inventors have formed a flexible portion 1 a at the upper portion of the water container 1 in the space where the water container 1 is stored when the water container is filled, as shown in FIG. 11 . A water container is previously formed in a large size ( corresponding to the absorption site 3a of Japanese Patent Application No. 8-271357) . When the bending portion 1a is formed in this way, the increase in volume due to the freezing of the water W inside the water container is absorbed by the space formed by the bending portion 1a to some extent cope with the increase in volume. It becomes possible.
[0007]
However, it is not preferable to set the bending portion large because the contact area of the water container 1 with the floor 51 is reduced. Moreover, even if it tries to enlarge the size of the water container 1 and enlarge the space part formed by the bending part 1a, the bending part comes into contact with water pressure, and the size of the space part due to the formation of the bending part 1a is There is a limit. Furthermore, formation of the deflection portion 1a is not only the capacity of the water container 1, it also depends on the water injection amount of injection water container 1, water injection is carried out by building workers before tensioning a floor construction site However, it is difficult to finely adjust the amount of water injection so as to give an appropriate deflection. If the amount of water injection is too large and the bent portion 1a is hardly formed, problems such as deformation of the floor surface may occur due to the volume increased by freezing of the water W.
[0008]
[Means for Solving the Problems]
Be those invention configured in view of the problems described above, with respect to space the water container is accommodated, or Ri by the placing directly deformation material in water in the container, the volume due to freezing of water It is the air-conditioning structure using the water container characterized by providing the means to ensure the space which absorbs the increase in this.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Sponge-like members, spring materials, or corrugated members, such as deformable and returnable members, are placed between the water container storage space and the water container, and these members increase the volume due to freezing of water. It is constituted so as to be absorbed by the deformation of. Further, the deformable member may be arranged in the water container and deformed in the water container.
[0010]
When the water in the water container freezes, the deforming member is deformed by the volume increase due to freezing, and a space for absorbing the volume increase is secured. On the contrary, when ice melting is started in the water container, the deformable member returns to the original amount corresponding to the decrease in the volume. For example, the water container and the back surface of the floor are separated due to a decrease in the volume of the entire water container. There is nothing.
[0011]
【Example】
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 spongy flexible material is disposed as a deformable material 3 between a bag-like water container (hereinafter simply referred to as “water container”) 1 and a floor lower support 2. When the water W in the water container 1 is frozen and the volume is increased, the flexible material 3 is deformed correspondingly, so that the volume increase of the water container 1 is absorbed. Further, since the deformable material 3 is formed to be porous, it becomes possible to exhibit extremely high heat insulation properties, so that the heat in the water container 1 is dissipated wastefully through the floor lower support portion 2. It is also possible to use it as a heat insulating material that prevents this.
[0012]
In the configuration shown in the figure, the water container 1 is also formed with the bent portion 1a. However, the increase in the volume due to freezing is absorbed by the deformation of the deformable material 3, and the bent portion 1a is the volume of the water container 1 itself. Therefore, it is sufficient if the size of the bent portion is large enough to accommodate the increase in the thickness of the bent portion. 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 assembling relationship with the deformable material can be clearly understood. The same applies to the following embodiments.
[0013]
FIG. 2 shows a second embodiment.
In this embodiment, a corrugated sheet material is disposed between the both sides of the water container 1 and the partition material 52 as the deformable material 4. In this configuration, the deformation of the water container 1 due to freezing is performed in both directions of the water container 1, and the wave shape of the deformable material 4 is deformed, so that a space corresponding to the expansion of the water container 1 is secured. Although not shown, the deformable material 4 may be disposed between the floor lower support material 2 and the water container 1 in the same manner as the flexible material, or the deformable material 3 which is a flexible material and You may make it use together.
[0014]
FIG. 3 shows a third embodiment.
Reference numeral 5 in the figure denotes a deformable material, which is formed of a sponge-like porous material, such as the flexible material 3 shown in FIG. For example, the deformable material 5 is formed in a cylindrical shape located in the longitudinal direction of the water container 1 or is formed as a plurality of independent lumps. Since the deformable material 5 is disposed between the floor lower support portion 2 and the water container 1, the water container 1 configured as a bag is deformed at the deformable material disposition portion by disposing the deformable material 5. The bent portion 1b is formed along the outer shape of the material.
[0015]
The increase in volume due to the freezing of the water W is absorbed by the deformable material 5 being reduced and deformed through the bent portion 1b. That flexure 1b in the water container 1 is, since the margin portion to absorb the increase in internal volume, as in the respective embodiments in this embodiment, rather than need to form a separate deflection unit 1a, the water container 1 It is possible to configure the entire upper surface of the substrate so as to be in close contact with the floor plate 51.
[0016]
FIG. 4 shows a fourth embodiment. Reference numeral 6 denotes a deformable material, which is disposed in the water container 1 unlike the three embodiments described above. Reference numeral 6 </ b> A in FIG. 5 indicates the structure of the deformable material 6. The deformable material 6 is formed in a cylindrical shape or a plurality of balls, and is stored in the water container 1. The deformable member 6 includes a sponge-like porous deformable portion 6a and a waterproof film 6b that covers the entire deformable portion 6a.
[0017]
The increase in volume due to freezing is absorbed by the deformation of the deformable material as shown by reference numeral 6B corresponding to the increase in volume. Incidentally, when there is no waterproof coating 6a, water has penetrated into the deformed portion itself, so that the effect of absorbing 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 bending portion 1a in the water container 1 as in the third embodiment.
[0018]
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 volume expansion, and the fourth embodiment of FIG. 4 is further simplified. It can be said. Reference numeral 7 denotes a space formed in the upper part of 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, the water vapor evaporated from the water W condenses in the upper part of the water container in close contact with the floor 51 and releases latent heat. That is, heat can be efficiently supplied to the floor 51 by the release of latent heat due to the circulation of water vapor between the water W and the upper part of the water container. The increase in volume due to freezing of the water W is absorbed by the space portion 7.
[0019]
FIG. 7 shows a sixth embodiment, in which a deformable material is arranged at at least one of the longitudinal ends of the water container 1 so as to secure a space for volume expansion. First, FIG. 7 (A) is corrugated deformation member 8 is arranged between the side edges and the partition member 52 of the end portion of the water container 1. The expansion of the entire volume of the water container due to freezing is concentrated at the end of the water container 1, and the deformable material 8 is deformed in response to the expansion, allowing the expansion of the entire volume of the water container 1. Incidentally, the water in the water container 1 is not instantly frozen, but a freezing part is formed in the water W corresponding to a decrease in the ambient temperature, and the sherbet until the internal water is completely frozen. Therefore, the expansion of the volume of the entire water container is concentrated in the space where the deformable material 8 is disposed due to the flow of the internal fluid.
[0020]
FIG. 5B 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 water container 1 is allowed to expand by bending and deforming in a direction in which the deformable material 9, which is a hairpin-shaped leaf spring, closes due to the expansion of the volume of the water container 1.
[0021]
FIG. 8 shows a seventh embodiment. This embodiment is a modification of the structure shown in FIG. 7B, and a hairpin-shaped leaf spring (denoted by reference numeral 10) is used as a deforming material between the end of the water container 1 and the floor lower support 2. Interposed. Expansion of the volume of the water container 1 is allowed by bending and lowering the side of the hairpin-shaped leaf spring 10 that supports the end of the water container 1 to the floor lower support part 2 side. . In this embodiment, the entire upper surface of the end of the water container 1 can be brought into close contact with the floor 51. Therefore, by arranging the deformable members 8 and 9 as shown in FIG. 7, the space portion does not become a non-contact space between the water container 1 and the floor portion 51, and the heat transfer efficiency can be increased accordingly.
[0022]
FIG. 9 shows an eighth embodiment. This embodiment is also a modification of the embodiment shown in FIG. 7B and FIG. In the drawing, a leaf spring (indicated by reference numeral 11) having a side shape bent into a hairpin shape as a deformable material is disposed between at least a part of the longitudinal side edge of the water container 1 and the partition member 52. . Expansion of the volume of the water container 1 has a configuration in which the side supporting the side edges of the inner water container 1 of the plate spring 11 is more acceptable to bend the partition member 52 side. Even in the configuration of this embodiment, the entire upper surface of the water container 1 can be brought into close contact with the floor 51 as in the case of the seventh embodiment.
[0023]
【The invention's effect】
