PROBLEM TO BE SOLVED: To overcome a problem in which a prior art chemical heat storage device shows a low thermal efficiency. SOLUTION: There are provided an adsorption material container 2 comprising an adsorptive material 3, a heater 4 and a radiator 5; a water container 6 provided with a heat exchanger 7; a water storing tank 11 for storing water; and a pipe 16 for connecting each of the aforesaid portions in a closed system. A water outlet pipe 13 of the water storing tank 11 and the radiator 5 for the adsorptive material container 2 are connected to each other, and a hot water taking means 19 for supplying hot water outside is connected to the radiator 5. Heat of the water container 6 can be recovered to the water storing tank 11 when the heat is stored, resulting in that a chemical heat storage device having a high thermal efficiency and an improved thermal radiation speed is attained. |
