Abstract:
Provided are a heat storage system and a heat storage method for a heat storage system with which energy consumption is reduced during cold storage. The heat storage system (S1) is equipped with a refrigerating machine (1) which cools cooling water, heat storage tanks (21, 22) which store cold heat, and a pump (31) that circulates cold water between the refrigerating machine (1) and the heat storage tanks (21, 22). The heat storage tanks (21, 22) include at least a first heat storage tank (21) in which a first heat-storing material (11) is arranged, and a second heat storage tank (22) in which a second heat storage material (12) having a higher melting point than the first heat storage material (11) is arranged, and the arrangement is such that cold water flows from the first heat storage tank (21) to the second heat storage tank (22).
