A new kind of adsorptive heat-storage compound material with excellent adsorptive performance was prepared by embedding CaCl 2 into meso-pore zeolite and using water as the circular liquid.The preparation of this material was introduced and the mechanism of adsorption and heat storage via reversible adsorption/desorption process was analyzed.Experimental research on the adsorption/desorption performance of the novel material and the heat-storage performance of the adsorption system was carried out.The experimental results show that the maximum equilibrium adsorption is up to 0.55 g per gram of dry sorbent,which is 2.529 times that of zeolite 13X and 2.688 times that of silica gel,and also show that the maximum adsorptive heat-storage density can reach 1.408 7×10 6 J/kg.
