按照自顶向下的软件开发方法的流程，本文首先分析了家用冰箱冰柜模拟软件的用户功能需求，接着讨论了家用冰箱及其部件在不同时间和不同条件下的动态特性，然后提出了建模和选型策略。在当今的模拟水平和计算机硬件水平下，适当考虑了压缩机的稳态模型、冷凝器和蒸发器的分相集总参数动态模型、毛细管的稳态模型以及箱体热负荷计算的z传递函数模型。基于上述策略的部件模型已成功用于家用冰箱冰柜模拟软件的开发。
According to the process of the software development method of From Top To Bottom? users?demands of functions of household refrigerator-freezer simulation software are analyzed at first, then dynamic characteristics of a household refrigerator and its components at different time and under different conditions are discussed, and next the model-building and model-selecting strategies are put forward in this paper. Under the simulation level and computer hardware level nowadays, the steady model of compressor, the separated-phase lumped-parameter dynamic models of condenser and evaporator, the steady model of capillary tube and the z-transfer function model for thermal load calculation of cabinet are considered appropriately. Components models based on the above strategies have been used for the development of simulation software of household refrigerator-freezers successfully.
