摘　　要：为指导大型客机辅助冷却系统的设计,针对机载蒸发循环和液体冷却循环相结合的辅助冷却系统,开发了系统稳态仿真模型。建立了适用于系统仿真的压缩机、换热器、电子膨胀阀等部件模型;对系统各单元之间的相互关系进行分析与解耦,建立了适用的系统求解算法。对系统性能随制冷剂充注量的变化趋势进行了预测分析,分析结果表明,辅助冷却系统稳态仿真模型对系统性能变化趋势的预测符合理论分析结果,模型可靠。In order to guide the design of the auxiliary cooling system, a steady-state simulation model of the aux- iliary cooling system forairlinerconsisting of airborne vapor cycle and liquid coolingcylce was developed. The compo- nent model of compressor, heat exchanger and electronic expansion valve suitable for system simulation was estab- lished ; the relationships among the the units of the system were analyzed and decoupled, and an appropriate system solving algorithm is established among. The performance of the system with the variation of refrigerant change was predicted and analyzed. The analysis results show that the prediction of the auxiliary coolingsystem performance ac- cords with the theoretical analysis results by the steady^state simulation model of the auxiliary cooling system, and the model is reliable.
