ABSTRACT:
Nowadays the refrigeration system plays a significant role in air cooling, food preservation etc. It is now almost impossible to imagine life without refrigeration system. Currently, cooling is primarily achieved with vapor compression system that uses a specific refrigerant to maintain the required temperature level. Even though the vapor compression system is effectively used, engineers are constantly trying to find better alternatives. This project brings into focus on one possible alternative.
This project is based on the principle of conversion of sound energy into thermal energy with the help of an acoustic driver system and a stack enclosed by a resonator tube. This system demonstrates the air cooling effect. It is an eco friendly system since this system works in an air medium (or any noble gas) and does not require any refrigerants.
The aim of this project is to demonstrate the cooling effect using sound waves in a small scale. With an experimental setup, the possibility of achieving a temperature difference of 10 K across the stack is demonstrated.
