中文摘要：

在固体吸附制冷循环中，实际的吸附（解吸）过程都是非平衡吸附过程，与理论循环之间存在较大差距。建立吸附式制冷系统吸附床传热传质数学模型，利用数值方法对数学模型进行求解。采用SCP（单位质量吸附剂的制冷功率）优先，同时兼顾COP（性能系数，印制冷量与加热量的比值）的策略，依据建立的吸附床传热传质数学模型进行计算，从而确定吸附式制冷系统循环的最佳周期是24min，并分析了吸附单元管的长度尺寸对整个制冷系统循环性能的影响。

英文摘要：

In the solid adsorption refrigeration system, the real cycle with non-equilibrium adsorption is different from the ideal cycle with equilibrium adsorption. To investigate the heat and mass transfer process inside the adsorption bed, mathematical models were established and solved numerically. The best cycle time 24 minutes was ascertain through the strategy of SCP priority and give attention to COP. The influence of the length of adsorption cell tube to the performance of refrigeration system was discussed.
