Résumé

A double-loop-type traveling-wave thermoacoustic refrigerator driven by a multistage traveling-wave engine was constructed. To reduce the onset temperature for thermoacoustic oscillations and achieve a refrigerator temperature of -100 °C, three etched stainless steel mesh regenerators were installed close to the sweet spot within the prime mover loop and one regenerator was fixed in the refrigerator loop. The maximum measured COP of the whole system at -50 °C, was 0.029. Gas oscillations occurred when the hot temperature of the regenerator in the prime mover loop exceeded 85 °C. On the other hand, refrigeration (-42.3 °C) was observed when the hot heat exchanger temperature reached 90 °C, which is lower than the boiling point of water. Furthermore, the refrigerator achieved a minimum cold temperature of -107.4 °C when the hot temperature was 270 °C.
