Abstract:  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 in-troduced and the mechanism of adsorption and heat storage via reversible adsorption／desorption process was analyzed．Ex-perimental 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 to0．55g per gram of dry sorbent‚which is2．529times that of zeolite13X and2．688times that of silica gel‚and also show that the maximum adsorptive heat -storage density can reach1．4087×106 J／kg．

Key words: adsorptive heat -storage, compound material, calcium chloride, zeolite
