This chemical heat-storage device 11 is provided with a controller 24 which, when NH3 is supplied to a reactor 12 from an adsorber 13, obtains the pressure change amount inside the adsorber 13 on the basis of the pressure inside the adsorber 13, and sets the NH3 adsorption amount of the adsorber 13, which is estimated using the pressure inside the adsorber 13 when the pressure change amount is equal to or less than a threshold value P, to the NH3 adsorption amount of the adsorber 13 during a state in which the NH3 recovery rate of the adsorber 13 is 0%. Furthermore, when NH3 is supplied to the adsorber 13 from the reactor 12, the controller 24 obtains the pressure change amount inside the adsorber 13 on the basis of the pressure inside the adsorber 13, and sets the NH3 adsorption amount of the adsorber 13, which is estimated using the pressure inside the adsorber 13 when the pressure change amount is equal to or less than a threshold value Q, to the NH3 adsorption amount of the adsorber 13 during a state in which the NH3 recovery rate of the adsorber 13 is 100%. |
