PROBLEM TO BE SOLVED: To keep the life of fine capsuled slurry long by obtaining heat storage density adapted to the concentration of the slurry. SOLUTION: There are provided slurry 11 where it acts as a heat storage member, and weight concentration of fine capsules in which there is encapsulated a core material including latent heat storage substances as chief components ranges from 40 to 53%, a heat storage tank 1 for storing the slurry 11, a centrifugal pump 6 for circulating the slurry in the heat storage tank 1, and a heat exchanger 2 for heat exchange between the slurry 11 circulated by the centrifugal pump 6 and a heat utilization medium. |
