いる。Thermal storage tanks have traditionally been used in cases where there is a lot of intermittent operation, such as in public spaces of broadcasting stations and hotels, and in cases where partial extended operation is required due to severe load fluctuations, such as in department stores and stores. It has been. A heat storage tank stores heat systematically and efficiently in a heat storage material such as water, so that there is no thermal or temperature loss, and allows the required amount of heat to be pumped out when needed. . At present, heat storage tanks are used for various purposes such as reducing the capacity of heat source equipment, recovering heat, utilizing waste heat, utilizing nighttime electricity, and shifting electricity peaks. Heat storage tanks were generally used frequently as cold water tanks, but recently they have also been used as hot water tanks for heat recovery heat pumps, solar heat utilization, etc.

る方法などがある。There are several types of heat storage materials depending on the purpose, but water is generally used because it is cheap, has a large heat capacity, and can be used directly as a heat medium in air conditioning equipment. Water has the highest specific heat per unit volume of light among all substances, and is also the cheapest substance, so it is the most commonly used substance in practical applications. Heat storage in water or solids uses only sensible heat, but latent heat storage releases heat when a liquid solidifies and absorbs heat when a solid melts, so a large amount can be stored in a small volume. The heat can be changed. Of course, sensible heat can also be used above and below the transition point. Issues include whether there is a substance that melts and solidifies just right for the desired and final heat storage temperature levels, corrosiveness to piping, and safety. Another important issue is the structure of the heat storage tank when using latent heat storage materials. If the structure is not such that heat transfer is always carried out effectively, melting and solidification will not occur smoothly, and the apparent heat storage capacity will be reduced. In particular, if it crystallizes during the solidification process, its thermal conductivity decreases, making it difficult to solidify even when the temperature drops. Methods for preventing this supercooling phenomenon include adding nuclear material that solidifies easily, and applying stirring or vibration to promote solidification.

Mouth: Using a single medium such as old wood as a heat storage material,
When storing latent heat using the heat of transition during the phase change between the solid and liquid phases, it takes a very long time to solidify the entire heat storage material due to its low thermal conductivity in the solid state. expensive and impractical. For example, in a type of heat storage tank equipped with corrugated pipes through which cooling water flows, only the heat storage material around the corrugated tubes solidifies, while the heat storage material in areas further away from the corrugated tubes is difficult to solidify, and as a result, the entire heat storage material It has been difficult to achieve effective heat storage by In addition, in order to solidify the entire heat storage material quickly and increase the heat storage effect, it was devised to fill a narrow space with heat storage material like a plate type heat storage device, but in a narrow space, the volume is small and the amount of heat storage is limited. Therefore, it is difficult to put it into practical use.

We aim to provide the following.

There is nothing that can prevent the pump from restarting. In this way, normal operation of the fluidized heat storage device is always guaranteed.

の負荷に利用される流体が供給される。Embodiments of the present invention will now be described with reference to the drawings. The heat storage device shown in Fig. 1 includes a heat storage tank (2) containing a heat storage material, a heat exchanger (4) connected to the heat storage tank via a pipe, and a heat storage material interposed in the middle of the pipe. It also includes a circulation pump (6). The heat exchanger (4) is supplied with a fluid used for loads such as air conditioning and heating, which indirectly exchanges heat with the heat storage material.

に固相の懸濁したいわゆるスラリー又はゾルとなる。Since the heat storage material needs to be circulated in this way, it must have fluidity. Such fluidity of the heat storage material can be achieved by temperature control, that is, by keeping the heat storage property in an incompletely solidified state, but it is also possible by imparting the following characteristics to the heat storage material itself. That is, a mixture of at least two mutually immiscible substances that have different freezing points and undergo a phase change between a liquid phase and a surface phase, in a temperature range below the freezing point of one substance and higher than the freezing point of another substance, This results in a so-called slurry or sol in which a solid phase is suspended in a liquid phase.

シャーベット状を呈する。For example, a heat storage material used as a heat source for heating can be obtained by mixing water and stearyl alcohol. The freezing point of fresh water is 0°C, and the freezing point of stearyl alcohol is 57.95°C. Stearyl alcohol is insoluble in water, so when the two are mixed and stirred or vibrated, at a temperature higher than the freezing point of stearyl alcohol, the liquid stearyl alcohol will form fine particles in the liquid water. The result is a mixture of dispersed colloidal dispersions, or an emulsion. Temperature 57.95℃
When the temperature is lowered to below, the stearyl alcohol coagulates, but at this time, the fine particles of stearyl alcohol are bridged with each other by water, so this heat storage material has excellent thermal conductivity, and the stearyl alcohol particles in each part are Solidifies uniformly and quickly. However, in a temperature range below the freezing point of stearyl alcohol and higher than the freezing point of water, this heat storage material becomes a sol with a solid phase (solidified stearyl alcohol) suspended in a liquid phase (water), forming a slurry or sherbet-like sol. present.

温度領域においては、この蓄熱材はゾル化してスラリー
もしくはシャーベット状を呈する。Further, FOP (cold) material used as a cold source for air conditioning can be obtained by mixing water and decyl alcohol. Decyl alcohol is insoluble in water and has a freezing point of 7°C. When the two are mixed and stirred or vibrated, the decyl alcohol is dispersed as fine particles in the liquid water, forming an emulsion. Decyl alcohol solidifies when the temperature is lowered to 7°C or less, but at this time, the fine particles of decyl alcohol are bridged with each other by water, so this heat storage material has excellent thermal conductivity, and the decyl alcohol in each part Alcohol particles coagulate uniformly and quickly. Thus, in a temperature range below the freezing point of decyl alcohol and higher than the freezing point of water, this heat storage material becomes a sol and takes on the form of a slurry or sherbet.
かくしてこれらの蓄熱材はいずれも熱伝導性に優れるの
みならず、所望のいわゆる不完全凝固状態に維持するこ
とが容易である。Thus, all of these heat storage materials not only have excellent thermal conductivity, but also can be easily maintained in a desired so-called incompletely solidified state.

６）の稼働を常に保証する。The circulation of the heat storage material is based on the fluidity obtained in this way, but for some reason, once the bomb is stopped, the dispersed phase in the heat storage material solidifies while also trapping the liquid phase dispersion medium between them. However, as a result, there is a possibility that the entire heat storage material in the heat storage tank (2) solidifies (gels). If this happens, it will be impossible to restart the pump (6). In consideration of this situation, measures have been taken to proactively secure the amount of dispersion medium necessary for circulation in the heat storage tank (2). The embodiment shown in FIG. 1 is a case where the dispersion medium has a higher specific gravity than the dispersed phase. That is, at the bottom of the heat storage tank (2) there is a compartment (12
) is installed protrudingly. On the other hand, if the dispersion medium has a lower specific gravity than the dispersed phase, as shown in FIG. 2, a compartment (22) is attached to the upper part of the heat storage tank (2) to accommodate the overflowed dispersed phase. In either case, the suction piping of the pump (6) is taken out from these compartments (12) (22), and the dispersed phase in the main body of the heat storage tank (2) takes in the dispersion medium and becomes a gel, solidifying the heat storage material as a whole. Even at the time, the painting room (
12) Ensure a free dispersion medium in (22) and pump (
6) to ensure the operation of the system at all times.

れるから、装置の連続した稼動が保証される。According to the present invention, since the heat storage material is circulated in a so-called incompletely solidified state, the volume occupied by the entire device is small compared to conventional heat storage in a solid state, and efficiency is high. In addition, the heat storage material has high fluidity in an incompletely solidified state, making it easy to handle and suitable for automatic control. Furthermore, even if the heat storage material in the heat storage tank solidifies as a whole, there is always enough fluid required for circulation, so continuous operation of the device is guaranteed.
