Abstract
In this study, a thermoacoustic refrigerator, using a resonant standing acoustic wave. has been built. The refrigerant is helium gas. The description of thermoacoustic refrigerator was Presented. The temperature ratio (cold part temperature over hot part temperature) and the COP (Coefficient of Performance) that normalized by carnot's COP are plotted versus the thermal load applied to the cold end, for- various speaker power.
