EXPERIMENTAL INVESTIGATION ON A THERMOACOUSTICALLY DRIVEN TRAVELING-WAVE THERMOACOUSTIC REFRIGERATOR IN ROOM-TEMPERATURE RANGE

本文报道了热声驱动的室温行波热声制冷机的实验研究。以氦气为工质研究了平均充气压力、工作频率等参数对制冷性能的影响。实验达到的最好结果为:最低温度为-47℃,在-20℃的制冷量为80W,按输入制冷机的P-V功计算,相应的制冷系数COP达到1.6左右。

Experiment on a thermoacoustically driven, traveling-wave refrigerator operating in room-temperature range was reported in this paper. Influence of different parameters on the thermoacoustic refrigerator with helium gas was investigated. The refrigerator achieved a no-load cooling temperature of-47°C, 80 Watts at-20°C and a COP of about 1.6 based on P-V power input.
