PURPOSE:To promote the evaporation of an adsorptive substance by a method wherein valves and a capacity variable tank are attached to a communication pipe for establishing communication between a heat accumulation tank and a storage tank. CONSTITUTION:When the adsorptive substance 4 adsorbed by a heat accumulating material 2 decreases gradually in quantity at the time of heat accumulation, the pressure of vapor generating as a result of vaporization of the adsorptive substance also lowers to reduce the difference from the pressure of vapor within the storage tank 3 so that the separation of the adsorptive substance from the heat accumulatng material 2 is delayed. In the above condition, when the valve 9B is closed and the capacity of the capacity variable tank 10 is increased, the pressure in the heat accumulating device is reduced and the evaporation and separation of the adsorptive substance 4 from the heat accumulating material 2 are promoted. Thus, when the pressure in the device comes close to a balanced condition and the transfer speed of the adsorptive substance 4 becomes slow, the valve 9A is closed and the valve 9B is opened to thereby maintain a heat accumulating condition. On the other hand, when the valve 9A is opened and the capacity of the capacity variable tank 10 is reduced at the time of initiation of heat generation, the vapor generating as a result of evaporation of the adsorptive substance 4 stored in the tank 10 is transferred quickly to, and adsorbed by, the heat accumulation tank 1 so that the operation of the heat accumulating device at the time of initiation of heat generation is accelerated. |
