Title:
HEAT STORAGE DEVICE, HEAT STORAGE SYSTEM, AND HEAT STORAGE METHOD
Document Type and Number:
WIPO Patent Application WO/2019/054120
Kind Code:
A1
Abstract:
The present invention provides a heat storage device, a heat storage system, and a heat storage method, wherein heat loss can be reduced while suppressing an increase in operation costs and while preventing a state in which an energy shortage occurs even when the extraction of heat has proceeded. This heat storage device is provided with: a heat storage tank that contains a heat storage material having heat storage capability and heat radiation capability; a heat source machine that generates heat to be supplied to the heat storage material; a first heat medium flow path through which a first heat medium flows, and which is thermally connected to the heat storage material and the heat source machine; and a plurality of temperature sensors which are disposed inside the heat storage tank and measure the temperature of the heat storage material. The plurality of temperature sensors are disposed at positions that are different distances away from the heat transfer surface of the first heat medium flow path, the heat transfer surface being in contact with the first heat medium flow path and the heat storage material. The heat source machine generates heat on the basis of the detection results of the plurality of temperature sensors.
