Loudspeaker-driven thermoacoustic refrigerators utilize the rich interactions between thermo-dynamics, acoustics and heat transfer to create a refrigeration effect by using the imposed acoustic wave, which is one form of mechanical work, thus employing the ability of a sound wave to play the role of a compressor and an expander. This work presents experimental data acquired on a standing-wave thermoacoustic refrigerator equipped with a set of structured stacks (200, 400 and 600 cells per square inch) and driven by a commercial loudspeaker. The dimensions of the acoustic resonator was adjusted to enforce equality between the acoustic resonance frequency and the mechanical resonance frequency of the loudspeaker. Experiments were carried-out up to a drive ratio of 11.2%. The results quantify the temporal development of the hot and cold stack temperatures for a range of vital parameters that significantly affect the performance of these refrigerators. The parameters considered were the operating frequency, the input drive ratio, the Lautrec number and the normalized stack position inside the acoustic resonator. When other factors were held constants, the coldest temperature on the stack took place when the operating frequency coincided with the mechanical resonance frequency, and when the stack porosity corresponded to a Lautrec number of 2.8, and when the normalized stack center position was equal to 0.193.
