摘要

Thermoacoustic refrigeration technology has drawn attention due to its environmentally friendly and reliable characteristics. However, its development is constrained by theoretical limitations, with the optimization of regenerators being a key research focus. This paper reviews the research progress of regenerators in thermoacoustic refrigeration machines, including the aspects of filling materials and structures. At the same time, it introduces the application of various algorithms, including the response surface method, and genetic algorithm, in the optimization design of regenerators. These algorithms have their advantages and disadvantages, and the application of multiple algorithms has promoted the development of regenerators. In the future, regenerator research will continue to develop in the areas of materials, structures, and algorithm optimization to achieve the improvement of thermoacoustic refrigeration machine performance.
