PROBLEM TO BE SOLVED: To increase an amount of heat utilization temporarily.SOLUTION: A latent heat storage device includes: a container having lower space for accommodating a latent heat storage body, and upper space which is space above the lower space and in which a heating medium having specific gravity smaller than that of the latent heat storage body accumulates; an inflow pipe having a discharge port for allowing the heating medium to flow into the latent heat storage body from the outside of the container on the outer peripheral surface; an outflow pipe having an inlet for allowing the heating medium in the upper space to flow out of the container on the outer peripheral surface; an inflow/outflow control unit for allowing the heating medium in the upper space to flow out of the container from the inlet of the outflow pipe so that a flow rate can vary, and allowing it to flow into the latent heat storage body from the discharge port of the inflow pipe so that the flow rate can vary via a waste heat area heat exchanger or a heat utilization area heat exchanger; and a liquid level sensor for detecting a liquid level of the heating medium in the upper space. |
