摘要：

The purpose of the study is to enhance CaO regeneration in the heat storage mode of a chemical heat pump using Ca(OH)2/CaO reaction. The effect of the condensation conditions and the effect of the supplied heat temperature level to the Ca(OH)2 particle bed on heat storage characteristics were investigated experimentally and theoretically. The following results, were found, i) Both the reaction temperature and the reaction eqilibrium pressure were lowered by the condensation enhancement. ii) The overall reaction rate of Ca(OH)2 dehydration was accelerated and the practical operating limit temperature in the heat storage mode could be lowered.
