中文摘要：
研制了一台采用新型复合吸附剂的吸附式冷冻机组，并对该机组进行了性能测试。测试结果表明，新型复合吸附剂在加热过程和冷却过程中的导热系数分别为0．72W·m^-1·℃^-1和0．56W·m^-1·℃^-1，复合吸附剂的强导热性能结合吸附单元管翅片强化换热，使得吸附床在冷却和加热过程中的传热系数达到了745．4W·m^-1·℃^-1和832．6W·m^-1·℃^-1，与以前类似的系统相比，性能分别提高了265％和300％。吸附剂的平均吸附速度达到了3．5×10^-4kg·kg^-1．s^-1，比文献中的平均吸附速度提高了30％。说明新型复合吸附剂不仅可以提高吸附床的传热性能，而且可以提高吸附剂的传质性能，大大缩短了吸附式冷冻系统的循环周期，提高了机组单位质量的制冷量。
英文摘要：
An adsorption chilling system with a new type of composite adsorbent was developed and its performance was tested in our study. The experiment results show that the thermal conductivity of the new type of composite adsorbent in the heating process and the cooling process is 0.72W·m^-1·℃^-1 and 0.56W·m^-1·℃^-1, respectively. Combined with the enhanced heat transfer by the fin tube, the heat transfer coefficient of the adsorber in the heating process and the cooling process is 745.4W·m^-1·℃^-1 and 832.6 W·m^-1·℃^-1, respectively. The performance of the present system increases by 265% and 300%, respectively, compared with the existing systems. Moreover, the average adsorption rate of the adsorbent is 3.5×10^-4 kg.kg^-1·s^-1, 30% greater than that in literature.
