PURPOSE:To enable to collect heat from latent heat accumulating materials or to accumulate heat in the materials in a short time by a method wherein a plurality of heat accumulating vessels containing the latent heat accumulating materials of different boiling points, respectively, are disposed within a heat accumulating tank in the flow direction of a fluid in the tank in such a manner that the vessels are arranged in sequence in the order beginning from the vessel having the heat accumulating material of the lowest boiling point and ending with that having the heat accumulating material of the highest boiling point. CONSTITUTION:The fluid 8 of low temperature is flowed from an inlet pipe 4 toward an outlet pipe 5 at the time of heat radiation. In this case, the fluid 8 is heated to an elevated temperature by receiving heat from the heat accumulating materials 2a-2d but since the heat accumulating materials of higher boiling points are arranged in the flow direction of the fluid 8, the difference in temperature between the fluid 8 and the heat accumulating materials is kept substantially constant with respect to the flow direction of the fluid. As a consequence, the amounts of heat radiation from the heat accumulating vessels 1 become substantially equal to one another and the entire amount of heat radiation from the vessels as a whole increases. Therefore, in case where a large amount of heat is required temporarily, this is extremely advantageous and hence it is possible to collect heat from the heat accumulating materials or to accumulate heat in the materials in a short time. |
