• We had proposed chemical heat pumps using a reversible calcium sulphate/water reaction system for effective waste energy utilization. However, more reaction kinetics studies are necessary for this reaction system, especially for different atmosphere condition and different materials. As a result, the reaction equilibrium line of CaSO<SUB>4</SUB> in the closed system like CHP system was found to be close to that in the open system. It means that the CHP using CaSO<SUB>4</SUB>/CaSO<SUB>4</SUB>·1/2H<SUB>2</SUB>O reversible reaction stores under 373 K level thermal energy, and releases the same level hot heat and 273 K level cold heat. Furthermore, the effects of material size on the reaction rates could be calculated by the proposed equations, which enable the effective CHP reactor design.
