た。 This heat storage device has good heat exchange efficiency and is also effective in transferring heat to the heat storage tank and the heat exchanger. However, when attempting to utilize the stored heat, there is a problem in that it is difficult to obtain heat at a constant temperature if the heat load on the heat utilization system fluctuates.

Summary The present invention aims to solve the problems of the conventional latent heat type heat storage device described above, and has two heat storage media that are independently circulated in slurry form outside the heat storage tank to store and radiate heat. Furthermore, this object is attempted to be achieved by exchanging heat between the respective heat storage media.

It is characterized in that heat is exchanged between the respective heat storage media, and the heat storage media are circulated outside the heat storage tank so that one side is exchanged with the heat source and the other side is exchanged with the utilization system.

られる危険も避けることができる。Effects According to the heat storage device of the present invention, fluctuations in the heat supply level of the heat source or the heat load level of the utilization system can be alleviated, and constant and stable heat can always be supplied to the utilization system. This means that the heat storage medium that supplies heat to the utilization system (utilization system side heat storage medium) is always supplied with heat from the second heat storage medium (heat source side heat medium) that has a higher transition point or melting point. This is thought to be due to the fact that the amount of heat stored in the heat storage medium on the utilization side is always stable. On the other hand, since the heat source side heat storage medium also supplies heat to the utilization system heat storage medium, it is possible to avoid the risk of the latent heat storage agent being excessively heated in the heat source.

Heat Storage Tank The principle of the heat storage device of the present invention can be expressed as shown in FIG. Note that the reference numerals used in FIG. 2 correspond to those shown in FIG. 1. As mentioned above, the gist of the present invention is that "two heat storage media are independently circulated in the form of slurry outside the heat storage tank to store and release heat, and furthermore, heat is exchanged between the two heat storage media." be. Therefore, the purpose of the present invention can be achieved using the principle shown in Fig. 2, but in order to obtain efficient heat exchange and more stable heat dissipation characteristics, it is necessary to use a heat storage system consisting of a retention section for each heat storage medium. It is preferable to provide a tank so that heat can be exchanged efficiently within the tank.

熱交換できるようになつている。 The inside of the heat storage tank is divided into two fluidly insulated spaces A and B by a partition wall 1 made of a heat conductive material, such as copper, and a coiled tube wall 2, and each space is filled. The heat storage medium (details will be described later) is designed to prevent mixing with each other and to allow heat exchange.

It is a dispersed slurry.

188℃, 89℃, 48℃, and the latent heat is 307KJ/Kg,
It is said to be 139KJ/Kg and 199KJ/Kg. It goes without saying that these can be used alone in the present invention, but it is also possible to use a mixture of two or more of them, so that a heat storage medium having a desired transition point and heat storage amount most suitable for each circulation line can be used. can be obtained.

In general, it can be said that the higher the slurry concentration is, the more advantageous it is in terms of the amount of heat storage, but since the fluidity is poor, it is necessary to determine the slurry concentration appropriately when operating the heat storage device. Needless to say. The concentration of the slurry used in the present invention is preferably 5 to 60% by weight, more preferably 30 to 50% by weight.

マによる架橋、その他によればよい。 Another specific example of the heat storage medium used in the present invention is a polyethylene molded body whose surface is infusible, such as particles, dice, or other shapes that can be made into a slurry. Infusibility of only the surface of these molded bodies may be achieved by coating with silane-modified polyethylene and crosslinking thereof, crosslinking with ion plasma, or the like.

コール、シリコーン油、水、その他、がある。 The liquid heat transfer medium used in combination with the polyethylene molded body is selected from among those that do not dissolve infusible polyethylene. The above-mentioned surface infusibility of the polyethylene molding is accompanied by crosslinking of the polyethylene, and as a result, the polyethylene is usually insoluble, so most non-corrosive liquid substances are made of this type. It could be used as a heat transfer medium in some cases. Specifically, there are ethylene glycol, propylene glycol, silicone oil, water, and others.

おいては蓄熱媒体の転移点あるいは融点の差は少
なくとも５度以上あることが好ましい。 In addition, in the present invention, since heat is transferred from the circulating heat storage medium on the heat source side to the circulating heat storage medium on the utilization system side, the transition point or melting point of the circulating heat storage medium on the heat source side may be equal to that of the circulating heat storage medium on the utilization system side. It needs to be higher than that. In the present invention, it is preferable that the difference in transition point or melting point of the heat storage medium is at least 5 degrees or more.

よつて循環するようになつている。 The heat storage medium filled in one space of the heat storage tank flows out from the heat storage tank through the communication port, and is transferred to the heat source (for example, a solar collector) through the heat source side circulation line 10.
The slurry pump 11 circulates the slurry so that the slurry is introduced into the heat storage tank 9, stores heat there, and then flows into the same space of the heat storage tank again.

ラリーを循環させる様にすることもできる。 In addition, in the present invention, the slurry concentration and component ratio of the heat storage medium remaining in the heat storage tank (heat storage medium in the heat storage tank) are determined based on the slurry concentration and component ratio of the heat storage medium to be circulated in the utilization system side circulation line (utilization system side heat storage medium). It doesn't necessarily have to be the same. for example,
The heat storage medium inside the heat storage tank can be removed by circulating the supernatant of the heat storage medium slurry filled in the heat storage tank through the circulation line on the utilization system side, or by installing a net at the outlet of the heat storage tank to screen out the heat storage agent. It is also possible to circulate a slurry having a different desired heat capacity, component ratio, or concentration.

と供給されるわけである。 As mentioned above, the heat storage tank is designed so that each heat storage medium can perform heat exchange, that is, heat transfer from the heat storage medium on the heat source side to the heat medium on the utilization system side. Therefore, the heat from the heat source is transferred to the heat storage tank, and then The heat is supplied from the heat storage layer to the utilization system.
熱源側蓄熱媒体は蓄熱槽の外側でない空間へ充
填することが好ましい。 It is preferable that the heat source side heat storage medium is filled in a space other than the outside of the heat storage tank.

降温し始めたので実験を終了した。 (2) Heat dissipation process The regulating valve 18 in the circulation line on the utilization system side is closed, the regulating valve 17 is opened, and heat is supplied to the utilization system. The circulation line was flowed at a rate of 10 liters/minute, and the temperature of the heat storage tank outlet line of the circulation line was maintained at about 168°C for about 1 hour.
The experiment was terminated as the temperature began to fall.
