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。
Based on the D-R equation, the adsorption-desorption process is described more accurately based on the thermodynamic analysis. In the model given, the physical meaning of each parameter in the D-R equation is reconsidered, and the effects of working medium on the thermophysical properties such as specific heat capacity, latent heat and so on are also considered. Based on the model, the influence of several important factors such as the nature of working pair, circulating conditions, cycle characteristics, especially the heat capacity of adsorber on the performance of adsorption refrigeration / heat pump system are analyzed, which provide the optimal design and optimal operation of the system A theoretical reference.
