The basic object of this paper is compression of refrigerant by the consumption of high amplitude sound waves that results the generation thermal Energy. For generation of sound waves a loud speaker (or common audio speaker) has been employed for creating high amplitude sound waves which compresses refrigerant (helium) by the well Known thermodynamics process of heat absorption. A Thermo acoustic refrigerator is fabricated with a cooler and loud speaker. The acoustic power produced by a loud speaker as a sound waves reaches to heat the pump. The cooler works on a reverse Carnot cycle by incorporating a compact acoustic network to create the travelling wave phasing necessary to operate. As the acoustic wave propagates temperature difference occurs at the ends of stack, heat and cold is trap by the heat exchangers regenerator from a cold heat exchanger to an ambient one. Instead of using co-axial topology network, the toroidal is used. The design, construction and performance measurement of the cooler are also discussed. Finally, at 8 C a coefficient of performance 7.0 is achieved.

A novel approach to design and fabrication of thermo-acoustic refrigerator using high amplitude sound waves
