Document Type and Number:
Japanese Patent JP6906432
Kind Code:
B2
Abstract:
To provide a heat storage system capable of storing heat discharged from a fuel cell device in both of hot heat and cold heat states.SOLUTION: A heat storage system is constituted to allow a heat storage medium to flow inside and outside of a heat storage tank 1 through an upper port formed at an upper side of the heat storage tank 1 and a lower port formed at a lower side of the same. The heat storage medium taken out from the lower port of the heat storage tank 1 is heated by an exhaust heat medium, and then the heat storage medium is allowed to flow to return to the upper port of the heat storage tank 1 in executing a hot heat storage operation for newly storing the heat storage medium of relatively high temperature in the heat storage tank 1, and the heat storage medium taken out from the upper port of the heat storage tank 1 is cooled by a second exchange portion 38 of a heat acoustic refrigeration device 30, and then the heat storage medium is allowed to return to the lower port of the heat storage tank 1, in executing a cold heat storage operation for newly storing the heat storage medium of a relatively low temperature in the heat storage tank 1.SELECTED DRAWING: Figure 1
