建立了沸石水吸附式制冷系统吸附床在非第一类边界条件时的二维传热传质模型。考虑了工质对的吸附特性对脱附过程的影响，讨论了肋片数量、肋片物性参数、吸附床的有效导热系数、接触热阻等参数对脱附时间的影响。结果表明，增加肋片可以改善吸附床的性能，其中肋片的数量和接触热阻的影响较大，肋片的物性参数影响不大。 A two-dimensional heat and mass transfer model of adsorbent bed for zeolite-water adsorption refrigeration system under non-first-type boundary conditions was established. The influence of the working material pairs’ adsorption characteristics on the desorption process was considered. The influences of the number of fins, the physical properties of the fins, the effective thermal conductivity of the adsorbent bed and the contact resistance on the desorption time were discussed. The results show that the addition of fins can improve the performance of the adsorbent bed. The number of fins and the thermal contact resistance are greatly affected, and the physical parameters of the fins have little effect.
