摘　　要：通过现有的成型的流体网络理论和热动力学理论,建立了整体斯特林制冷机系统的网络模型,从计算和实验两个角度定性分析了排出器和活塞行程配比对于制冷机系统性能的影响;提出了可供制冷机结构优化的无量纲因子参数。同时,上述方法可以帮助简化实验过程,为寻找最佳工况点提供了重要依据。The integral - Stirling refrigerator network model is established by the mature theory of fluid network and thermodynamic. From both calculation and experiment, this paper has the analysis of the relationship between the ratio of piston displacement to displacer＇s and the engine performance ;dimensionless factors are obtained from the calculation here as important parameters for the working condition optimization. This is also an important method for the simplification of the experimental process and work condition optimization.
