热驱动型热声斯特林制冷机是当今世界关注的热点，它利用热声热机驱动热声斯特林制冷机，具有可靠性高、操作简单等优点。该系统适用于天然气液化，通过燃烧少量天然气使其余部分液化。提出了一种带线性电机相位调节器的热驱动型热声斯特林制冷机。使用直线电机不仅可以为制冷机提供合适的声场以实现高性能，而且可以将膨胀功转化为电能。从而大大提高了系统的效率。由于系统中热能、声功、冷功和电能之间的能量转换机制复杂，本文仅通过调整负载电阻和等效电感来研究制冷机与直线电机之间的耦合关系。仿真结果表明，当温度为110 K时，冷却功率为463.1 W，相对卡诺效率为31.3%，电功率为553.7 W，总火用效率为53.7%。由于该系统采用了多台制冷机和电动机，为天然气液化提供了一条新的途径。
Nowadays, heat-driven thermoacoustic Stirling refrigerator is of great interest in the world, which utilizes thermoacoustic heat engine to drive thermoacoustic Stirling refrigerator with high reliability and simplicity. This system is suitable for natural gas liquefaction by burning a small amount of natural gas to liquefy the rest. In this paper, a heat-driven thermoacoustic Stirling refrigerator with linear motor phase adjuster is proposed. The linear motor is used to not only provide a suitable acoustic field for the refrigerator to achieve a high performance but also convert the expansion work into electricity. Thus, the system efficiency can be greatly improved. Due to the complicated energy conversion mechanism between heat, acoustic work, cooling power and electric power in the system, here we only try to investigate the coupling relationship between refrigerator and linear motor by adjusting load resistance and equivalent inductance. According to the simulation, optimum results of a cooling power of 463.1 W at 110 K with relative Carnot efficiency of 31.3%, an electric power of 553.7 W and a total exergy efficiency of 53.7% are achieved. Since several refrigerator and motor units are used in this system, this technology may provide a new way for natural gas liquefaction.
