Experimental Analysis In The Implementation Of The Thermo-Acoustic Refrigeration System By Means Of Air As A Working Medium

Abstract

A more contemporary technique that has recently received attention from the scientific society is thermoacoustic refrigeration. It
involves using acoustic sound waves to generate low temperatures. A thermoacoustic refrigeration system is a device that uses acoustic
sound energy as an input to transport heat via a solid material known as a stack in a resonator tube. The temperature differential formed
throughout the stack affects how well thermoacoustic refrigerators work. The thermoacoustic system's stack is its most important
component. The honeycomb-shaped stack, constructed of Mylar material, is employed in the current experimental investigation. The
system and the experimental data were analyzed using a combination of set independent and dependent variables. The working medium
of the system was air, and it was operated at different pressures and resonance frequencies to ascertain the optimal performance
parameters of the device. The results are presented, and they are consistent with the notion that the thermoacoustic refrigeration system's
capacity to operate at its peak depends critically on the stack and the parameters that affect it. The study provided makes suggestions
for enhancing thermo acoustic refrigerators' efficiency, which is currently lacking as a result of their rather underwhelming
performance. Changes to the resonance frequency and resonator tube material can both enhance the system's performance coefficient.
