In a heat storage system using two or more kinds of latent heat storage materials having different melting points, even if supercooling occurs in a latent heat storage material on the high melting point side, the supercooling can be quickly released. A heat storage system 1A passes through heat storage tanks 21 to 23 that individually accommodate each of the latent heat storage materials 31 to 33, and the heat storage tanks 21 to 23 in order of increasing melting point of the latent heat storage materials in the heat storage tank. A flow path 4 that supplies the heat medium to one end 4 a of the flow path 4, and a distribution path 72 that extracts the heat medium from the other end 4 b of the flow path 4. The flow path 4 has connecting portions 43 and 45 interposed between the heat storage tanks 21 to 23. Distribution control means 82 and 83 are provided in the bypass paths 73 and 74 that branch from the supply path 71 and reach the communication portions 43 and 45. [Selection] Figure 1 |
