First claim
Opening claim text (preview).
What is claimed is: 1. A reaction material for a chemical heat pump, comprising: type III anhydrous gypsum; a magnesium compound; and Ca x Mg 1-x SO 4 , wherein the reaction material for the chemical heat pump structurally changes between a compound including type III anhydrous gypsum, the magnesium compound, and Ca x Mg 1-x SO 4 , and a compound including hemihydrate gypsum, a hydrate of the magnesium compound, and a hydrate of Ca x Mg 1-x SO 4 when subjected to heat storage process and heat release process, and x is 0<x<1. 2. The reaction material for the chemical heat pump of claim 1 , wherein the magnesium compound includes one compound or more selected from a group of magnesium sulfate, magnesium nitrate, magnesium acetate, magnesium hydroxide, magnesium benzoate, magnesium chloride, magnesium bromide, and magnesium iodide. 3. The reaction material for the chemical heat pump of claim 1 , wherein Ca x Mg 1-x SO 4 has a crystal structure in which at least one part of calcium site of type III anhydrous gypsum is substituted with magnesium. 4. The reaction material for the chemical heat pump of claim 1 , wherein the reaction material for the chemical heat pump has a diffraction peak derived from a crystal structure of type III anhydrous gypsum or of hemihydrate gypsum. 5. A chemical heat pump, comprising: a reaction member; an evaporator-condenser member; a connecting member; and an opening-closing mechanism, wherein the reaction member includes the reaction material of claim 1 , the evaporator-condenser member condenses or evaporates water, the connecting member connects the reaction member and the evaporator-condenser member, and the opening-closing mechanism controls opening and closing of the connecting member.
