DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a latent heat storage medium in a heat storage system for storing heat using inexpensive nighttime electric power and utilizing the heat for air conditioning such as cooling and heating in the daytime or cooling and heating in various industrial fields. It relates to a heat storage element used as a heat storage.

[0002]

2. Description of the Related Art In recent years, due to the tight power demand and the difficulty of constructing a new power plant, there has been a demand for the technical development of a power load standardization system for effectively using night power and suppressing the use of daytime power to save energy. Have been. Such a thermal storage cooling and heating system using nighttime electric power requires a thermal storage tank in which a number of capsules containing a thermal storage agent for storing thermal energy are housed, for example.

[0003]

However, such a heat storage tank becomes large in size and is greatly restricted in an installation place. In addition, a heat storage tank having a size corresponding to an air-conditioning area must be prepared, and the cost is high. There was a problem. In particular, in a small-scale air-conditioning system such as a general house, the restriction on the installation location, coupled with the high cost, is a serious adverse effect of introducing the system.

Accordingly, the present invention does not require a tank of a predetermined size, and cuts a required length according to an air-conditioning area, or combines a required number of cuts into a predetermined length to obtain an underfloor. The main object of the present invention is to provide a latent heat storage element that can be installed at a location such as a vehicle, thereby reducing costs and clearing restrictions on the installation location.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the heat storage body according to the present invention, an outer cylindrical body formed around the inner cylindrical body 1 with an inner cylindrical body 1 through which a refrigerant fluid flows and a space 3 for filling a heat storage material. 2 and a plurality of radial ribs 4 connecting the inner and outer cylindrical bodies 1 and 2 are integrally formed in a state of having flexibility by a synthetic resin material. Then, the pipe body 5 is cut into a predetermined length, the space 3 is filled with a heat storage material, and the openings 3 a and 3 b at both ends of the space 3 are sealed with a lid 6.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION At both ends of the pipe body 5, it is preferable to cut off the outer cylinder 2 together with the ribs 4 to expose the inner cylinder 1 to form a joint portion 1a. This is convenient for interconnecting the plurality of heat storage bodies A cut to a predetermined length.

In order to enhance the heat storage efficiency, it is preferable to cover the outer peripheral surface of the pipe body 5 with a cover 7 made of a heat insulating material.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below with reference to the embodiments shown in FIGS. In the drawing, reference symbol A denotes a heat storage body according to the present invention, which is formed around the internal cylinder 1 with a space 3 for filling a heat storage material and an internal cylinder 1 through which a refrigerant fluid flows. Pipe body 5 composed of the outer cylindrical body 2 and the plurality of radial ribs 4 connecting the inner and outer cylindrical bodies 1 and 2 are integrally formed in a state where flexibility is given by a synthetic resin material. Have been. As shown in FIG. 3, the pipe body 5 is cut into a predetermined length, the space 3 is filled with a latent heat storage material, and the openings 3 a and 3 b at both ends of the space 3 are sealed with a lid 6. .

In this embodiment, the outer cylinder 2 is cut off together with the ribs 4 at both ends of the pipe 5 to form the inner cylinder 1.
Are exposed to form joint portions 1a, 1a.
The outer peripheral surface of the pipe body 5 is covered with a cover 7 made of a heat insulating material.
Is coated to the extent that flexibility is not impaired.

The internal cylinder 1 is preferably formed as thin as possible within a range that does not impair the strength, in order to enhance heat transfer with the external heat storage material.

As shown in FIG. 3, the latent heat storage agent sealed in the space 3 of the heat storage body A is sealed with a slight air space left. The latent heat storage agent is selected according to the use of the heat storage system, for example, sodium acetate, sodium acetate compound, calcium chloride hexahydrate in a high temperature range, sodium chloride aqueous solution, ammonium chloride aqueous solution in a low temperature range,
Examples include an aqueous solution of potassium chloride, an aqueous solution of potassium hydrogen carbonate, an aqueous solution of sodium carbonate, and water.

The heat storage body A formed as described above has a desired length and is bent in a zigzag shape to an arbitrary size suitable for the size of the installation place as shown in FIG. 4, or as shown in FIG. As shown in FIG. 6, a plurality of pieces are wound in a spiral shape or cut into a predetermined length as shown in FIG. A refrigerant fluid is caused to flow through the cylindrical body 1 to perform heat exchange with the latent heat storage material filled in the outer space 3. in this case,
It is preferable that the entire heat storage assembly be packed in a heat-insulating outer case, a net, or any other material so as to maintain the aggregate form. Also, the length and number of the heat storage units may be increased or decreased according to the conditions such as the location of the heat storage unit, the storage space, and the desired heat storage capacity.

In the above embodiment, the inner cylindrical body 1 is exposed at both ends of the pipe body 5 so that the joints 1a, 1
Although a is formed, it is also possible to directly connect a connecting pipe to the inner cylindrical body 1 opened at the cut end face shown in FIG. 1 without forming the joints 1a, 1a.

FIG. 8 shows another embodiment of the heat accumulator according to the present invention, in which the outer cylindrical body 2 and the ribs 4 are formed with gentle waveforms in cross section. This makes space 3
The repeated expansion and contraction of the volume due to the temperature change of the latent heat storage material filled therein can be absorbed to alleviate the fatigue of the outer cylinder.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to these embodiments. For example, the lid 6 that closes the openings at both ends of the space 3 may be sealed with, for example, a lid shape of a container, or may have any configuration as long as the structure can seal the space 3. In addition, the present invention has the above-mentioned constitutional requirements, achieves the object of the present invention, and can be appropriately modified and implemented within the scope of the following effects.

[0016]

Since the heat storage element according to the present invention is constructed as described above, it does not require a tank having a fixed size as in the prior art, and is adapted to the air-conditioning capacity and the size and conditions of the installation storage space. Can be assembled in any desired form by combining the required length or the required number of cut to predetermined lengths. It can be installed or stored in a space such as a corner, and can save much cost because an expensive tank is not required.
In addition, by dividing the heat storage body into a portable size, there is an effect that transportation, carrying in and out of the floor can be facilitated, and installation and maintenance can be easily performed.
