斯特林制冷机作为斯特林制冷机的一种重要类型，在民用领域和航天技术中都得到了广泛的应用。然而，斯特林冰箱现有的许多型号都兼容一种特定的型号，准确地反映现实和给出解析解之间通常存在矛盾。根据热声理论，认为声学惯性、声学柔度、回热器内的流动阻力和工作空间内的热力学过程是影响斯特林制冷机整体性能的主要因素。因此，本文采用传输线模型和多元营养过程方程，提出了一种适用于各种类型斯特林制冷机的通用模型，该模型能够给出能揭示一些基本原理的解析解。通过比较发现，通用模型的简化算例与已有的一些模型是等价的，并且通用模型与实验和斯特林制冷机模拟软件之间的一致性很好，验证了通用模型和解析解揭示的原理。该通用模型适用于各种类型的斯特林制冷机，能够较好地反映实际情况，并提供了一种利用解析解对斯特林制冷机的性能进行参数分析的方法，这将有利于热效率的优化。
The Stirling refrigerator, as an important type of Stirling machine, is widely used in both civil area and space technology. However, many of the existing models of the Stirling refrigerator are compatible with one specific type, and there is usually a contradiction between reflecting the reality accurately and giving an analytical solution. Based on the thermoacoustic theory, it is assumed that the acoustic inertance, the acoustic compliance, the flow resistance in the regenerator and the thermodynamic process in the working spaces are the major factors that affect the overall performance of the Stirling refrigerator. Therefore, by adopting the transmission line model and the polytrophic process equation, this paper proposed a general model which is applicable to various types of Stirling refrigerators and is able to give analytical solutions that can reveal some basic principles. By comparison, the simplified cases of the general model is found to be equivalent to some of the existing models, and a good agreement is achieved among the general model, the experiment and a Stirling refrigerator simulation software, which verifies the general model as well as the principles revealed by the analytical solutions. Applicable to various types of Stirling refrigerators, the general model is able to reflect the reality in a satisfactory way and provide an approach to parametrically explore the behavior of Stirling refrigerators with the analytical solutions, which will benefit the optimization of the thermal efficiency.
