Abstract
As a new technology for effective utilization of electric energy, a chemical heat pump unit for night-electric heat-storage and cold/hot heat-recovering in daytime air-conditioning/hot-water-supply is proposed and a prototype is made. The basic heat-releasing characteristics and the effects of reactant particle amount and heat recovering condition on the characteristics are studied experimentally.<BR>It is found that the electric energy stored as densely as 1.86 MJ/kg-CaO in the form of thermochemical energy is released in the form of thermal energy as cold heat at around 273 K and hot heat at around 500 K. The heat is recovered as cold heat for air-conditioning at around 275 K and hot-water at around 350 K. The total amount of reactant particles should be determined with a balance of heat-loss, although heat releasing is improved by using a shallow bed with a small amount of particles. Furthermore, the recovered heat amount is found to be enlarged because of increased reactivity of reactant particles when the heat-recovering rate is properly controlled.
