摘　　要：针对吸附床及其换热流体建立了传热传质耦合的动态模型,并对该模型进行了数值求解,得出了吸附剂的温度场;探讨了多个因素对单位吸附床质量制冷功率(SWP)的影响。研究表明:吸附床结构参数、传热热阻以及循环时间对SWP的影响比较大且存在最佳值使系统SWP最大。A dynamic simulation model of heat and mass transfer of adsorber bed and heat/cooling fluid is presented. The model is solved by numerical method and the temperature field of adsorbent is obtained. With this model, effects of many factors on the parameter of SWP which shows output of refrigerating capacity per kilogram adsorber are studied. Results show that the structure parameter, heat resistance and cycle time play an important role on the SWP.
