Thermoacoustic Refrigeration

Abstract

Thermoacoustic refrigeration technology is a green alternative for the conventional refrigeration system in vehicles. The former uses environmentally friendly inert gases whereas the latter uses chemical refrigerants that can have severe impacts on the environment. In order to apply thermoacoustic technology commercially, the conventional sensitive and complex Acoustic drive needs to be replaced with an alternative robust acoustic source. The design of a new compact thermoacoustic refrigerator is described in this study. This thermoacoustic refrigerator uses a Rotary Drive Mechanism as an alternative to conventional Acoustic source which is a relatively compact and robust mechanism. The technical details of design, fabrication, and testing processes are presented. Also the fabricated model is Experimentally Analyzed by integrating different stack materials into the new Rotary Drive Mechanism as a new Acoustic source system to evaluate its effects on performance.
