Abstract: Use of CFC-contained systems has caused severe environmental hazards that have researchers looking for alternatives. Studies have shown that thermoacoustic technology is suited a candidate for conventional vapour compression cooling system in particular for special uses. In this research, theoretical, numerical and experimental studies were completed to identify optimum operating conditions for the design, fabrication, and operation of a thermoacoustic refrigerator. The system uses no refrigerant or compressor, and the only mechanical moving part is the loudspeaker connected to a signal generator that produces the acoustics. Here air at 1 atm is used as the working gas. The system fabricated with this grant is made of PVC and brass with a sinusoidal section to reduce power loss and can operate up to a maximum of 4 bar. The system can be taken apart if different stack geometry or material is to be studied.
