CHEMICAL HEAT STORAGE DEVICE

摘要

A chemical heat storage device to heat an object to be heated, wherein the chemical heat storage device comprises: a reactor for heating the object to be heated, said reactor having a heat storing material which generates heat by means of a chemical reaction with a reaction medium and which stores heat by desorbing the reaction medium when heated; a reservoir that stores the reaction medium to be supplied to the reactor and recovers the reaction medium desorbed from the heat storing material; a connecting pipe that connects the reactor and the reservoir and forms a flow path in which the reaction medium flows; a valve that is provided in the connecting pipe and opens and closes the flow path; a control unit that controls opening and closing of the valve; an actual movement acquisition unit that acquires the actual amount of movement of the reaction medium moving between the reactor and the reservoir; an estimated movement acquisition unit that acquires the estimated amount of movement of the reaction medium that is estimated to move between the reactor and the reservoir on the basis of valve-opening control that is performed by the control unit to move the reaction medium between the reactor and the reservoir; an abnormality detector that detects an abnormality when the difference between the actual amount of movement acquired by the actual movement acquisition unit and the estimated amount of movement acquired by the estimated movement acquisition unit is greater than or equal to a threshold value.
