PROBLEM TO BE SOLVED: To provide a reaction material for chemical heat pump capable of suppressing changes of a crystal structure from III type anhydrous gypsum to II type anhydrous gypsum even when repeating heat storage and heat release.SOLUTION: There is provided a reaction material for chemical heat pump consisting of a mixture containing III type anhydrous gypsum, KSOand CaKSOand capable of reversible changes each other between the mixture and a mixture containing hemihydrate gypsum, KSOand CaKSOhydrate by a heat storage and heat release process, where 0<x<1. The reaction material is obtained by at least mixing and firing at least calcium sulfate and KSO. |
