摘　　要：涂层吸附床能够降低吸附剂间的热阻提高吸附床传热性能,是一种高效吸附床。文中采用COMSOL Multiphysics软件建立了局部非热平衡的二维板翅式吸附床模型,开展板翅式吸附床性能数值模拟;采用制冷性能(COP)和单位质量吸附剂制冷能力(SCP)分别对不同翅片形状吸附床(三角形翅片吸附床、梯形翅片吸附床与六边形翅片吸附床)的性能进行分析和评价。研究发现:驱动热源为333—363 K时,随着热源温度的升高,3种不同结构的板翅式涂层吸附床的COP和SCP都随之增大;在相同的条件下,3种不同翅片结构的板翅式吸附床中,六边形翅片吸附床的COP最大,其值为0.514;而梯形翅片吸附床的SCP最高,其值为848.61 W/kg。The coated adsorber is considered as the advanced adsorber because of decreasing the interparticle thermal resistence to enhance heat transfer performance of adsorber.A transient two dimensional local thermal non-equilibrium model was built by COMSOL Multiphysics to analyze the adsorber performance by numerical simulation.COP and SCP was used to evaluate the performance of different fin shape adsorbers(triangular fin adsorber,trapezoidal fin adsorber and hexagon fin adsorber).The results show that COP and SCP of plate-fin coated adsorber increase with raising heat source temperature at the heat source temperature 333-363 K.Under the same operating condition,the hexagonal fin adsorber had the highest value of COP with the value of 0.514.Meanwhile,the trapezoidal fin adsorber had the highest SCP value 848.61 W/kg.
