[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an under-floor ice storage tank.

[0002]

BACKGROUND OF THE INVENTION Brine is circulated in a closed cycle,
There is known a heat pump in which heat is taken from brine by an evaporator in a refrigeration cycle at a predetermined point in the circulation path, the heat storage medium is frozen by the taken heat brine to store cold heat, and the stored cold heat is used for air conditioning or the like. Have been.

In such a heat pump, a conventional ice heat storage tank for storing cold heat is often installed outdoors, such as on the roof of a building or in a machine room, and its general configuration is as shown in FIG. I was In the ice heat storage tank shown in FIG. 1, a watertight closed space is formed by an inner container 1 made of a thin metal plate, and a peripheral wall of the inner container 1 is reinforced by a number of ribs 2 to deform the inner container 1 due to a change in internal pressure. Insulating the inside and the outside by attaching the heat insulating material 3 around the inner container 1, improving the appearance by surrounding the heat insulating material 3 with the decorative plate 4, and deficient in the heat insulating material 3 during transportation. And so on. A heat insulating plate 5a made of rubber is provided on the bottom of the box surrounded by the decorative plate 4.
And a base plate 5b for installation, and heat transfer from the box body to the base plate 5b is suppressed by the heat insulating plate 5a.

[0004]

However, the conventional ice heat storage tank has a large bulky shape with a vertical dimension H1 due to the fact that it is installed outdoors, so that there is a problem that the transportation cost increases. . Further, in addition to manufacturing the inner container 1 having a large number of ribs 2, it is necessary to attach the heat insulating material 3 to the inner container 1 and the decorative board 4 to the heat insulating material 3, so that the material cost is reduced. And the production cost increases.

On the other hand, recently, there has been an increasing demand for comfortable air-conditioning not only for commercial buildings but also for living spaces of ordinary houses. However, the conventional outdoor-installed ice heat storage tank described above is difficult to install in a general house because it is bulky. Therefore, it was conceived to install an ice thermal storage tank using the space under the floor of a general house.

The present invention has been made in view of the above problems, and can be installed using a narrow space under the floor.
In addition , while maintaining the required pressure resistance performance,
Transport, construction, and construction costs
It is an object of the present invention to provide an under-floor type ice heat storage tank which can be configured at very low cost .

1 is a sectional view of an under-floor ice storage tank A according to an embodiment of the present invention. In the figure, reference numeral 6 denotes a high-pressure material made of concrete, which has a base portion 61 having a flat inner surface and a rectangular annular beam portion 62. A metal plate or a resin plate is used for the recess 63 surrounded by the base 61 and the beam 62.
A thin flat inner container 7 separately manufactured at a factory is housed in a floating state, and the inner container 7 between the inner container 7 and the wall surface of the recess 63, that is, the inner surface of the base portion 61 and the inner surface of the beam portion 62. the gap throughout the construction site of the gap formed around the
And is filled with a synthetic resin foam 8 hardened by injection .
The ice heat storage tank A includes a tank body A1 and a lid A2, and the above-described configuration is applied to the tank body A1. Further, the lid A2 may be in contact with the floor plate 10 of the living space S, or may be separated as shown.

In such an ice heat storage tank A, the inner vessel 7
In the internal space, for example, heat storage units in which a heat storage medium is sealed in a sealed bag are arranged and loaded, and brine flows through a passage formed between the heat storage units.

In the case of the ice heat storage tank A having the above structure, the inner container 7
Has a flat shape, so that the vertical dimension H of the ice heat storage tank A can be easily set to a dimension corresponding to the vertical width of the narrow space under the floor as shown in the figure, and by doing so, the ice heat storage tank A You will be able to put it in a small space under the floor of ordinary houses without difficulty. Further, in this ice heat storage tank A, the internal pressure of the inner container 7 is supported by the surface pressure of the synthetic resin foam 8 supported by the high pressure-resistant material 6, so that the inner container 7 is
There is no need to reinforce. In order to increase the support force of the synthetic resin foam 8, it is desirable that the synthetic resin foam 8 be hard.

The high-pressure material 6 made of concrete can use a slab or an underground beam or the like which is constructed as a foundation when building a building. Can be omitted, which is extremely useful for reducing the manufacturing cost of the ice heat storage tank A and the cost of transporting the material.

[0013] into the gap between the wall surface of the synthetic resin foam 8 inner container 7 and the recess 63 which houses float in the recess 63 surrounded by the base portion 61 and the beam portion 62 of the high withstand voltage material 6 It is easily formed by injecting a synthetic resin and foam-hardening it.
Also, a hand for holding the inner container 7 floating in the recess 63.
As the step, as shown in FIG. 1, means for mounting the inner container 7 on the support members 9 scattered at a plurality of positions of the base portion 61 of the recess 63 is adopted. The support 9, material having small thermal conduction rate, such as a resin or wood polygonal or made of synthetic resin foam 8 and homogeneous synthetic resin, polygonal cylindrical, polygonal cone, a cylinder, a cylinder, a cone Etc. can be used. Support 9 made of such a material
When using, the support 9 itself functions as a heat insulating material, and therefore, there is an advantage that the heat insulating performance of the synthetic resin foam 8 is not impaired by the support 9.

Although the high-pressure material 6 is made of concrete in the embodiment described above, the high-pressure material 6 may be a frame made of wood, or may be formed by digging soil under the floor to form a recess having a flat bottom. It may be formed by performing the above.

[0015]

As described above, according to the present invention, since the inner container has a flat shape, the entire shape can be easily flattened. Therefore, there is an effect that it can be easily installed in the space under the floor of a general house having a small vertical width.

In addition, the space around the inner container is formed by the high pressure resistant material.
