Abstract
A phase separation of a salt hydrate as a heat accumulating medium is prevented, thereby maintaining a heat accumulating density of a heat accumulator for a long period of time. A heat accumulating pipe contains Ba(OH).sub.2 .cndot.8H.sub.2 O as a heat accumulating medium which is not subjected to supercooling and a sphere movable in the heat accumulating pipe. A heat insulating vessel having a cooling water inlet pipe and a cooling water outlet pipe is filled with the heat accumulating pipes. By vibrating a heat accumulator having an agitating function which includes the heat accumulating pipes and the heat insulating vessel, the sphere moves in the heat accumulating pipe to agitate the heat accumulating medium, so that a distribution of water becomes uniform and a phase separation is prevented.
