<p>PROBLEM TO BE SOLVED: To shorten a heat storage/discharge time, in a heat storage system using a temperature stratification type heat storage tank which generates a temperature stratification layer in the heat storage tank by supplying a heat medium cooled by a refrigerator to the heat storage tank in which a latent heat storage material is arranged.SOLUTION: A heat storage system 1 comprises: a refrigerator 2; and a heat storage tank 21 which stores heat by heat-exchanging with cold water generated in the refrigerator. The heat storage system 1 supplies cold heat which is stored in the heat storage tank via pipes 5a, 5b, to a heat-exchanging unit 6 which is arranged indoors. An aggregate 11 formed of latent heat storage materials is arranged in the heat storage tank. There are arranged: a first cold water circulation passage which supplies the cold water generated in the refrigerator to the heat storage tank, and returns the cold water which is heat-exchanged in the heat storage tank to the refrigerator; and a second cold water circulation passage which circulates the cold water in the heat storage tank. The second cold water circulation passage: has a plurality of distribution pipes 4g which are arranged at the upstream side of the latent heat accumulation materials in the vertical direction so that a flow of the cold water in the heat storage tank forms a temperature stratification layer; and also has a plurality of aggregate pipes 4h which are arranged at the downstream side of the aggregate of the heat storage materials in the vertical direction.</p> |
