PROBLEM TO BE SOLVED: To provide a chemical heat storage device in which a reaction medium adsorption amount of an adsorber can be accurately recognized in each of a state in which a reaction medium recovery ratio of the adsorber is 0% and in which it is 100%.SOLUTION: A chemical heat storage device 11 includes a controller 24 that acquires a pressure change amount in an adsorber 13 on the basis of a pressure in the adsorber 13 when NHis supplied to a reactor 12 from the adsorber 13, sets a NHadsorption amount of the adsorber 13 estimated on the basis of the pressure in the adsorber 13 when the pressure change amount becomes a threshold value P or less, to be as the NHadsorption amount of the adsorber 13 when the NHrecovery ratio of the adsorber 13 is 0%, further acquires the pressure change amount in the adsorber 13 on the basis of the pressure in the adsorber 13 when NHis supplied to the adsorber 13 from the reactor 12, and sets the NOadsorption amount of the adsorber 13 estimated by using the pressure in the adsorber 13 when the pressure change amount becomes a threshold value Q or less, to be as the NHadsorption amount of the adsorber 13 in a state in which t the NHrecovery ratio of the adsorber 13 is 100%.SELECTED DRAWING: Figure 3 |
