摘　　要：提出并研制一种新型粘贴干燥剂颗粒的内冷却紧凑式叉流固体除湿器,描述了这种除湿器的物理和数学模型,运用隐式差分格式数值求解该除湿器的偏微分控制方程组,模拟除湿器的动态除湿过程。通过实验得到了该除湿器的实际动态除湿性能,并将除湿器除湿性能的数值模拟结果与实验结果与进行了比较。实验和模拟计算结果均显示:该文研制的新型除湿器在高湿、低湿环境工况下都有良好的除湿性能;实验与计算的结果比较表明,本文所采用的内冷却紧凑式固体除湿器数学模型的数值解与实验结果吻合良好。该文研究结果对研制新型固体除湿(干燥)器具有很好的参考价值和应用价值。An internally cooling compact solid dehumidifier was proposed and built. The thermodynamic model was described and developed simulating dynamic dehumidifying process using implicit finite difference method. Comparison between computer results and experimental results on performance of the dehumidifier indicated that the numerical results are in good agreement with the experiments and this new type of solid dehumidifier has excellent performance under both humid and less humid conditions. The results in this paper may provide a useful base for design and rmming optimization of new type of solid dehumidifier.
