FIG. 8 shows an example in which a system is constructed using these heat storage (cool storage) panels 10. Heat storage (cool storage) panels 10D, 10B, 10B, 10D, 10C,
By connecting 10C, 10D, 10E, 10E, and 10D as shown in the figure, a large area is uniformly stored (cooled).
System can be configured.

In the above description, the heat storage (cool storage) panel 10
Have been described as rectangular, but the heat storage (cold storage) panel 10 may be rectangular, or may be rectangular or other shapes in accordance with the installation location.

As described above, when the heat storage (cool storage) system according to the present invention is used in a refrigerator room or a refrigerator, a heat storage (cool storage) panel is incorporated in the entire wall surface to thereby improve the temperature distribution in the room (inside the refrigerator). The change can be reduced, and nighttime electric power can be used for heating (cooling) of the heat storage (cooling) panel, so that the running cost can be reduced. Further, since the humidity in the refrigerator can be kept high and no airflow is generated in the refrigerator, the refrigerator can be made free from moisture such as vegetables, and can be dried and burnt.

When such a heat storage (cool storage) system is used for an indoor cooling and heating system, a stable indoor temperature can be maintained by incorporating a heat storage (cool storage) panel on the floor, wall, or ceiling, and forced air It is possible to have a comfortable room without any.

[0068]

As described above, according to the present invention, a heat storage (cool storage) agent can be passed by passing a heat transfer medium such as steam or cold water from the outside without removing the once installed heat storage (cool storage) panel. Can be supplied with heat, so that the problems of the prior art can be solved. In addition, since it can be installed in combination with small heat storage (cool storage) panels,
The degree of freedom in installation location and shape is increased, and the heat storage (cool storage) panel that has been partially deteriorated can be easily replaced, so that maintenance can be easily performed.

Since the heating / cooling device (heat supply source) is separately provided from the heat storage (cold storage) panel, the heat storage (cold heat) space can be constituted only by the heat storage (cold heat) panel, and the body is light. This is true for refrigerated containers such as delivery vehicles,
Since no extra device is required, a large payload can be obtained.

It is only necessary to circulate cold water or steam as the heat transfer medium, which not only simplifies the circulating device but also does not adversely affect the environment if the heat transfer medium leaks to the outside. Absent. Further, the function according to the purpose can be exhibited only by replacing the heat storage agent.

Since the heat storage (cool storage) panel can be fixed to the heating (cooling) space, it is not necessary to put the heat storage (cool storage) panel in and out, so that labor can be saved. In addition, there is no need to circulate the heat storage (cool storage) capsule, and a simple configuration that does not require a heat storage (cool storage) capsule storage tank can be provided.
