Description of the Related Art Conventionally, a heat storage tank using a latent heat storage material composed of water, paraffin, a surface active material, and an antifreezing material has been known. The control such as the start of heat storage and the end of heat storage in the heat storage tank has been performed by measuring the change in the density of the latent heat storage material. For example, the density of the latent heat storage material at the start of heat storage is used as the initial value for starting heat storage.

御が適切に行えないという欠点があった。However, in the above-mentioned conventional one, at the start of heat storage, there is a density distribution of the latent heat storage material inside the heat storage tank, and the density measurement value may differ depending on the measurement position. There were many. This is because, as a property of the latent heat storage material, when left in a stationary state, there is a large difference in density between water and paraffin, so that water easily accumulates in the lower portion and paraffin in the upper portion. Therefore, there is a drawback in that the density as an initial value varies depending on the time of standing (non-use time, leaving time, etc.), and the heat storage tank cannot be controlled appropriately.

充分である。The density detecting device 3 not only changes the density,
The one that can measure the temperature change is used. This is because, if the evaporation of the water content of the latent heat storage material 2 is allowed from the inside of the tank 1, it is not sufficient to make the correspondence between the density change and the heat storage amount as described above, and further the correction due to the temperature change is added. It is necessary. However, when the tank 1 is sealed and the evaporation of the moisture of the latent heat storage material 2 from the tank 1 is not allowed, it is sufficient to take the correspondence between the density change and the heat storage amount.

ある蓄熱量を正確に把握できる。As described above, after the latent heat storage material 2 in the tank 1 is stirred, its density is measured by the density detection device 3, so that the latent heat storage material 2 becomes uniform in the tank 1 and the density is measured. There will be no error or the like. For this purpose, the control device 4 operates so that the density detecting device 3 measures the density of the latent heat storage material 2 after the stirring stirrer 5 has stirred the latent heat storage material 2. Usually, at the time of heat storage, at the time of heat storage completion, at the time of heat radiation, and at the time of heat radiation completion, agitation is performed, or immediately after agitation is performed. Therefore, even if density measurement is performed by the density detection device 3, the latent heat storage material is used. The inconvenience due to the non-uniformity of the temperature distribution of No. 2 does not occur. However, if it is left to stand until the start of heat dissipation or the start of heat storage, the density of the latent heat storage material 2 is measured after stirring to obtain a measurement error based on the uneven temperature distribution of the latent heat storage material 2. Can be prevented. As a result, the amount of heat storage which has a one-to-one relationship with the density can be accurately grasped.
