In this study, the coefficient of performance (COP) and relative coefficient of performance (COPR) of an air-based standing wave thermoacoustic refrigerator (ASWTAR) was investigated. All relevant components of the thermoacoustic refrigerator were fully available in the system. Heat pipes with a total heating power of 30W were installed into the cold-side and hot-side heat exchangers. The circular stacks with plugging ratios of 0.67, 0.71 and 0.74 and the spiral stacks with plugging ratio of 0.74 were tested and compared. The results show that the circular stack is the optimum stack geometry for ASWTAR. Similarly, a circular stack with a blockage ratio of 0.71 has the best performance, producing the lowest cold side temperature (T_c) and the highest temperature difference (ΔT_m). Under no cooling load and 2W cooling load, T_c, ΔT_m, COP and COPR were 22.4 °C, 30.5 °C, 0.93 and 9.57%, respectively. Finally, it is clear that due to the use of more suitable materials, the COP and COPR of a circular stack are greater than those of a spiral stack.

在这项研究中，研究了空气基驻波热声制冷机（ASWTAR）的性能系数（COP）和相对性能系数（COPR）。系统中完全可以使用热声制冷机的所有相关组件。将总热功率为30W的热管安装到冷侧和热侧热交换器中。测试并比较了堵塞率为0.67、0.71和0.74的圆形堆和堵塞率为0.74的螺旋堆。结果表明，圆形堆叠是ASWTAR的最佳堆叠几何形状。类似地，具有0.71的阻塞率的圆形叠层具有最佳的性能，产生最低的冷侧温度（T _{C ^}）和最高温度差（ΔT_米）。在无冷却负载和2W制冷负荷，T _Ç，ΔT_米，COP和COPR分别为22.4℃，30.5℃，0.93和9.57％之间。最后，很明显，由于使用了更合适的材料，圆形堆叠的COP和COPR大于螺旋堆叠的COP和COPR。
