This document describes the design and fabrication of a thermoacoustic refrigerator. Some key points:
1. Thermoacoustic refrigeration uses sound waves to alternately compress and relax gas particles in a tube, transferring heat without moving parts.
2. The refrigerator consists of a resonator tube containing a stack of closely spaced surfaces through which a sound wave oscillates. Heat is transferred between the gas and stack surfaces.
3. Experiments investigated different stack geometries and materials to optimize heat transfer and the refrigerator's performance. Temperature sensors measured the temperature difference created.
