Investigation of Thermoacoustic Refrigeration System for Three Different Stack Geometry with Helium Gas

Abstract

Numerous devices now in use could soon undergo a revolution because to recent advancements in the field of thermal acoustics. The thermo acoustic devices don’t include any hazardous chemicals or environmentally hazardous materials which are feature of modern refrigeration systems. In this research work, an experimental investigations are conducted using polynamide nylon 6 material for stack and helium gas as working fluid. For making solid foundation of the research work the three different stack geometry are studied and the performance comparison done on the aspect of coefficient of performance (COP) and the temperature differential occurs on both ends of the stack. The expérimentation done with a range of optimum drive pressure of 6 to 10 bar and a constant frequency of 500Hz. The spiral, parallel plate and honeycomb geometry of the stack is used. The two parameter are analysed with the working frequency, operating pressure, and cooling load. The end results of this investigation suggest that the incorporation of helium gas and honeycomb stack in TARs can lead their performance, potentially opening up new avenues for applications in refrigeration and cooling technologies.
