Abstract

To enhance the heat transfer of particulate zeolite, a new-style of composite blocks is proposed with expanded graphite, M(OH)_n, silica gel etc. as its constituents. By designing orthogonal tests and experimenting on simulative adsorption cooling systems, the optimum proportion of additives is determined. Experiments show that the dominant factor among the three additives is the expanded graphite constituent. The thermal conductivity of composite blocks can be increased to 6.2-8.6 times higher than that of particulate zeolite, and with molded adsorbents the coefficient of performance (COP) of simulative adsorption cooling system can increase by 23.8%.
