摘　　要：民机的空调组件舱位于非增压区,其内部包含有换热器、压缩机等高温环控组件。为避免高温对舱体结构产生危害,需要采用冷却措施。以某机型的空调组件舱通风冷却方案为参考,建立了空调组件舱通风系统的几何模型,并以此模型为基础进行了CFD仿真计算。对计算结果进行分析后,提出了方案的缺陷,并为后续的方案设计提出了关注点。Pack Bay in civil aircraft is located in unpressurized area,which contains high temperature components of ECS（ Environmental Control System）,such as heat exchanger,compressor and so on. In order to avoid high temperature damage to the structure,cooling method should be applied. In this article,a Pack Bay ventilation geometry model is built according to an existing configuration,and then CFD（ Computational Fluid Dynamics） simulation calculation is taken based on this model. After analyzing the calculation results,drawbacks of this configuration are listed,and recommendations for the future design are proposed.
