摘要
吸附床是吸附式制冷系统的核心部件,其传热传质性能的好坏直接影响到系统的制冷量。为了研究吸附床的传热传质特性,笔者建立了吸附式制冷系统中吸附床在非第一类边界条件时的一维传热传质的数学模型,并运用有限差分法对该数学模型进行了数值分析。该数学模型和计算结果有助于深入认识吸附床的传热传质特性。
Adsorbent bed is the core component of adsorption refrigeration system, its heat and mass transfer performance has a direct influence on the refrigerating capacity of the system. In order to investigate the heat and mass transfer properties of the adsorption bed, a one-dimensional mathematical model of adsorption bed is established for the second class boundary conditions, and governing equations in the mathematical model are dispersed with the format. The model and results are helpful to reveal heat and mass transfer characters of the adsorbent bed and to provide theoretical basis for optimal design of this system.
