【摘要】 以Ｄ－Ｒ方程为依据，在热力分析的基础上对吸附－解吸过程作了比较准确的描述。给出的模型中，重新考虑了Ｄ－Ｒ方程中各参数的物理意义，并充分考虑了工质对热物性如比热容、潜热等随温度变化的影响。基于该模型分析了几种重要因素如工质对的性质、循环工况、循环特性，尤其是吸附器的热容对吸附式制冷／热泵系统性能的影响，为系统的优化设计和优化运行提供了理论上的参考。更多还原

【Abstract】 In this paper,a thermal model based on Dubinin Radushkevich Eguation and thermodynamic analyses is given,which presents a complete and precise description of adsorption desorption cycles In this model, some physical properties with temperature such as specific heat of working pairs,isosteric heat of desorption or adsorption are particularly considered,several main factors affecting the performances of cycles are discussed according to the results of computer simulations,such as the characteristics of working pairs,the working conditions,especially the heat capacities of generators The relationship of the performance of cycle and these factors is initially investigated The performances of advanced cycles such as heat regenerative adsorption cycle are also analyzed and compared with that of basic adsorption cycle更多还原
