| 摘 要： | 针对余热驱动吸附式冷管单元(直径16mm,总长1020mm)制冷循环过程的变压吸/脱附特性,采用线性驱动力(LDF)模型,建立了动态的传热传质数学模型。对吸附式冷管的主要部件——吸附器和冷凝/蒸发器在加热解吸和冷却吸附不同阶段的工作过程,分别建立了耦合的动态方程。对所提出的模型进行分析和合理简化后,利用数值方法对模型进行了求解,获得了冷管单元吸附器、冷凝/蒸发器的循环工作参数的动态变化规律,计算结果与实验结果较好地吻合。为吸附式冷管单元及其组合式制冷系统进一步的优化设计和实用化的改进研究提供了重要参考。

| Abstract: | Utilizing the Linear Driving Force(LDF)model,a dynamic heat and mass transfer model for the pressure swing adsorption/desorption characteristics of the waste-heat-powered adsorption cooling tube module with 16 mm diameter and 1020 mm length was established.For the working process about of main parts of the adsorption cooling tube,including adsorber and condenser/evaporator,the coupled dynamic equations during each stage of heating/adsorbing and cooling/desorbing were set up,respectively.Being simplified reasonably,the model was figured out by using numerical method,and the dynamic varying laws of cycle working parameters of adsorber and condenser/evaporator of the cooling tube were obtained.The calculated results accord well with the experiment data.By means of the model,the simulation calculation and optimization design on the adsorption cooling tube and its multiple-bed combined refrigeration system can be implemented further. |
