Title: A Study of Standing-Wave Thermoacoustic Refrigerator
Abstract: Thermoacoustic refrigerator is a cooling device which uses the acoustic waves to produce the cooling effect. The aim of this paper is to explore the experimental and numerical feasibility of a standing-wave thermoacoustic refrigerator. The effects of the stack length, position of stack and operating frequency on the cooling performance are carried out. The circular pore stacks are tested under the atmospheric pressure. A low-cost loudspeaker is used as an acoustic driver. The results show that the location of stack installed in resonator tube has a greater effect on the cooling performance, than the stack length and operating frequency, respectively. The temperature difference across the ends of stack can be generated up to 13.7C, and the temperature of cold-end is dropped down by 5.3C from the ambient temperature. Keywords—Cooling performance, Refrigerator, Standing-wave, Thermoacoustics.
