The invention relates to the technical field of heat energy utilization, in particular to a chemical heat storage-heat release method and device. The chemical heat storage-heat release method comprises the following steps that a heat storage medium is mixed with water in a heat storage medium heat preservation tank, a combination reaction occurs, a heat release medium is generated, and heat is obtained; under the heating condition, the heat release medium is conveyed to a heat storage medium regeneration tank to be subjected to a decomposition reaction, and the obtained heat storage medium isconveyed to the heat storage medium heat preservation tank to be subjected to a combination reaction; an alkaline earth metal oxide is taken as the heat storage medium; and an alkaline earth metal hydroxide is taken as the heat release medium. According to the chemical heat storage-heat release method and device, redundant heat energy in some places can be transferred to buildings, equipment and residential areas lacking
