This project examines the effectiveness of thermo acoustic refrigeration, which is the theory of using sound waves as a coolant. The work reported here deals with the design and optimization of a thermo acoustic-refrigerator (TAR) as an attempt to address the future generation environment friendly energy systems. The literature survey gives a complete picture on the history of thermo acoustics and the work carried out in the field of thermo acoustics till today. The motivation of the design of thermo acoustic refrigerator explains the reasons for carrying out the work illustrating its benefits and how the performance of the TAR in future can be made efficient in comparison with the performance of a conventional refrigerator.
