Abstract
A heat accumulator includes a heat storage tank and a latent heat accumulating material which fills the tank. The heat accumulating material remains in a stable supercooled condition at temperatures lower than a predetermined phase transformation temperature, and is released from the supercooled condition by a releasing device. The releasing device includes a holding member, which is mounted on the storage tank such that it is capable of touching the accumulating material and which holds a seed material. A driving mechanism drives the holding member so that the seed material comes into contact with the heat accmulating material for a predetermined period of time, releasing the latter from its supercooled condition.
