Studies on applicability of scallop material to calcium oxide/calcium hydroxide chemical heat pump

摘要

From the viewpoints of energy savings and environmental impacts,we have been studying on chemical heat pumps(CHPs)especially using calcium systems.In this study,the applicability of a scallop to CaO/H_2O/Ca(OH)_2.CHP using hydration of calcium oxide and dehydration of calcium hydroxide as a new original material for the reaction systems was examined by thermogravimetry experiments and lab-scale CHP apparatus.As a result,the scallop CaO decomposed from scallop CaCO_3 was found to work as a reactant for CaO/H_2O/Ca(OH)_2.CHPs by some treatments of hydration repetition.
