ラリ，第３２頁〜第４１頁）に詳しく論述されている。To increase the heat storage property, it is sufficient to mix it with a heat storage capsule in water, but generally known capsules are large and do not have fluidity. Therefore, it has been proposed to store heat or cold heat in a fluid microcapsule. For example, this can be found in the literature (Chemical Engineering Society, “Heat Storage / Heat Increasing / Heat Transport Technology Research Group”; Chemical Engineering Symposium Series 23, Advances in Heat Storage / Heat Enhancement / Heat Transport Technology, Latent Heat Storage Material Microcapsule Slurry, No. 1) 32 to 41).

が可能となる。Since the heat storage material has a high heat storage density, the heat storage density can be increased by mixing it with the liquid as compared with the case where only the liquid is used as the heat storage material. As a result, when the liquid mixed with the heat storage body is heated or cooled to a certain temperature, the temperature can be maintained for a long time, and the desired temperature or the liquid having the desired temperature can be immediately obtained.

その集まった蓄熱体に対して蓄熱を行う。When the density of the heat storage body is substantially equal to the density of the liquid, the heat storage body flows along with the convection of the liquid during heat storage to store heat or cold heat in the heat storage body, thereby increasing the convective heat transfer coefficient. It is possible to store heat in a short time. When the density of the heat storage body is lower than that of the liquid, the heat storage body collects on the upper part of the liquid. Therefore, heat is stored in the collected heat storage body, and when the density of the heat storage body is higher than the density of the liquid. , Because the heat storage material gathers in the lower part of the liquid,
Heat is stored in the collected heat storage body.

Then, the liquid 2 convects as shown by an arrow A in the figure, the heat storage body 3 also flows along with the flow of the liquid 2, and the inside of the container 1 is in a turbulent state.

Since the upper outer surface of the container 1 is covered with the heat insulating material 11, the heat stored in the heat storage body 3 is not easily released to the outside. Further, since the liquid 2 in the lower part of the heat storage body 3 has a high temperature in the upper part thereof, convection does not occur and heat is not radiated from the liquid 2 side in the lower part.

As shown in FIG. 4, the liquid 2 is forced to flow in the container 1. The heat storage body 3 rides on the flow of the liquid 2 and flows from the upper portion to the lower portion of the container 2. At this time, since the outer surface of the lower portion of the container 1 is not thermally insulated, it functions as a heat dissipation surface. That is, the heat stored in the heat storage body 3 is radiated through the lower outer surface of the container 1, and this heat is used for heating the room and the like. In FIG. 4, the arrow indicates the heat transfer direction, and the arrow indicates the natural convection generated in the room.

適感が生まれる。If the lower part of the container 1 is made of a transparent plate (acrylic, glass, etc.) and the liquid 2 is transparent, the heat rays radiated from the heat storage body 3 can be directly guided to the outside. It becomes easier to perform radiant heating. In addition, the flow of particles in the heat storage body 3 can be directly observed, and the quality of convection and the presence / absence of a failure of the carrier can be grasped, and fashionable and comfortable feeling is created.

As shown in FIG. 5, in this modification, a wire mesh or grid 13 having a finer grain size than the heat storage body 3 is provided on the upper part of the container 1, and a heater 4 is provided on the lower part thereof. A carrier 12 is provided between the wire mesh (lattice) 13 and the bottom surface of the container 1. Then, during cooling, the carrier 12 is driven to dissipate the heat storage body 3 in the liquid 2 and radiate heat from the lower outer surface of the container 1 as shown in FIG. In this modification, since the heat storage body 3 does not directly contact the carrier 12, it is possible to prevent the heat storage body 3 from being damaged.

ている。(Fourth Embodiment) FIGS. 7 and 8 show a fourth embodiment of the present invention. This embodiment is effective for storing cold heat at room temperature or lower. As shown in FIG. 7, a liquid 2 is contained in a container 1, a heat exchanger 10 is provided in the lower part thereof, and a carrier 12 (pump, stirring propeller) is provided in the upper part thereof. The density of the heat storage body 3 is adjusted to be slightly larger than the density of the liquid 2. In addition, the lower outer surface of the container 1 is a heat insulating material 11
The outer surface of the upper part is not insulated but is exposed.

輸送されない。Since the density of the heat storage body 3 is higher than that of the liquid 2, the heat storage body 3 is gathered around the heat exchanger 10. When a refrigerant (CFC, antifreeze liquid, etc.) flows in the heat exchanger 10 in this state, the cold heat is transferred to the heat storage body 3 via the heat exchanger 10 and is stored therein. Since the lower outer surface of the container 1 is covered with the heat insulating material 11, this cold heat does not easily escape to the outside. Also, the liquid 2 above the heat storage body 3 does not cause convection because the lower portion is cooled, and the cold heat of the heat storage body 3 is not transported to the liquid 2 above it.

The heat storage body 3 flows along with the forced flow of the liquid 2 and flows from the lower portion to the upper portion. At this time, since the outer surface of the upper part of the container 1 is not thermally insulated, the cold heat stored in the heat storage body 3 is released through the outer surface of the upper part of the container 1 and used for cooling or the like. In FIG. 8, an arrow D indicates a heat transfer direction, and an arrow E indicates a natural convection generated indoors.

It is collected in a and is stored by being heated by the heater 4. During this heat storage, the heat storage body 3 having a density smaller than that of the liquid 2 does not flow into the upper duct 15 because the U-shaped duct 17 is provided. Therefore, the heat storage body 3 is efficiently stored by the heater 4 while being collected in the heat storage unit 1-a. Further, since the outer surface of the heat storage unit 1-a is covered with the heat insulating material 11, it is possible to suppress the heat radiation loss to the outside.
