摘　　要：为了探索斯特林型冷电联产系统高效可靠的耦合结构,基于热声分析方法和数值模拟,重点考察了串接电机、旁接电机和谐振管三种谐振耦合方式在斯特林型冷电联产系统的工作性能并开展了其对关键参数的敏感性分析。计算结果表明:谐振管耦合型斯特林冷电联产系统的效率小于串接电机型耦合系统,而大于旁接电机型耦合系统。但相比于串接电机型与旁接电机型,谐振管耦合型斯特林冷电联产系统性能对电机等效机械阻尼、运行压力和热端温度的敏感性小,能在较大的工况范围内保持高效运行。Based on the thermoacoustic theory and commercial software Sage, the performance and sensitivity to operating parameters of three coupling modes of series motor, parallel motor and resonance tube in Stirling-based combined cooling and power(CCP) systems are investigated. The results show that the exergy efficiency of the system coupling with a resonance tube is lower than that with a series alternator but is higher than that with a parallel alternator. The performance of the CCP system coupling with a resonance tube is more insensitive to the alternator’s mechanical resistance, operating pressure and heating temperature, ensuring the operation smoothly under the deviation from the rated operating condition.
