【摘要】 在分析了冰箱冷凝器、蒸发器的瞬态过程对系统动态过程影响较小后,对冰箱冷凝器、蒸发器采用了稳态模型,建立了冰箱仿真的准动态模型.通过动态模型及实验数据的比较发现,冰箱仿真采用准动态模型同样能与实验数据吻合得很好.运行中发现,准动态模型不仅提高了仿真程序运行的稳定性,而且程序运行的速度提高了25%左右.更多还原

【Abstract】 Based on the analysis that the transient characteristics of condenser and evaporator have little influence on dynamic performance of refrigerator/freezer,a quasi-dynamic model of refrigerator/freezer simulation was developed, in which steady models are developed for condenser and evaporator. The quasi-dynamic model predicts the performance of refrigerator/freezer as accurately as the dynamic model, but it is more stable and consumes 25% less time than the dynamic model.更多还原
