Abstract: In order to improve the adsorption capacity per unit mass of adsorbent， reduce bed volume， and choose chemical adsorption as refrigerant，the multi-generator absorption ice-making system was introduced. Then the heat transfer performance of unit pipe in the adsorbent bed was researched，and the system influence of unit pipe heat transfer resistance was also analyzed. Besides，some methods of reducing the thermal resistance of each part were discussed. The results show that the percentage of thermal resistance of convective heat transfer is 89%，while heat performance parameter of the adsorption ice-making system driven by ship exhaust is up to 25%.
