Study of a Thermoacoustic Refrigeration System with a Spiral Rubber Stack

Abstract

Thermoacoustic refrigeration technology converting sound energy into thermal energy offers environmental benefits including zero risks of ozone depletion or global warming potential due to the absence of hazardous refrigerants in the process. This study aims to investigate the effects of a spiral rubber stack on the cooling performance of a thermoacoustic refrigeration system made from an acrylic resonator tube. Air is used as a working gas. The results show that as time progresses, the temperature on the hot side of the stack increases, while that on the cold side of the stack reduces, leading to an increase in temperature difference across the stack. The findings of this study can potentially further expand knowledge and scientific experimental data in the field of thermoacoustic refrigeration.
