PROBLEM TO BE SOLVED: To stably maintain a temperature of output gas for any long period at a target temperature (approximately) constantly in a chemical heat pump.SOLUTION: This chemical heat pump includes: two reaction portions R1, R2 including a heat storage medium; an evaporation and condensation portion D including water and steam; connecting portions H18-H21 for connecting each of the reaction portions R1, R2 with the evaporation and condensation portion D; and two fluid passages provided corresponding to the reaction portions, respectively. A "first state where the reaction portion R1 is set in the heat storage state and the reaction portion R2 is set in the heat radiation state" and a "second state where the reaction portion R1 is set in the heat radiation state and the reaction portion R2 is set in the heat storage state" are attained alternately every time a first period passes. In each of the reaction portions, in the heat radiation state, fluid is made to flow from a first side toward a second side of the corresponding fluid passage over the first period, and in the heat storage state, the fluid is made to flow from the second side toward the first side of the corresponding flow passage over a second period.SELECTED DRAWING: Figure 1 |
