Abstract:
A method for forming a crystal nucleus in a latent heat storage material contains a solvent and a dissolved substance. The solvent contains water as the main ingredient. The latent heat storage material retains latent heat in a supercooled state. The method includes: (a) separating out an anhydride of the dissolved substance by heating or cooling part of the latent heat storage material in the supercooled state; and (b) supplying a droplet comprising water to the anhydride, to terminate the supercooled state of the latent heat storage material, and make the latent heat storage material dissipate heat.
Abstract:
A heat storage device includes a pair of electrodes; an alternating-current power source that applies an alternating-current voltage to the pair of electrodes; and a latent heat storage material that is disposed between the pair of electrodes, a supercooled state of the latent heat storage material being maintained by the alternating-current voltage.
