Thermo acoustic Refrigeration System

Cooling is generally obtained by vapour compression system using a specific refrigerant. But it has been recently found that the refrigerants are known to cause adverse environmental effects. In order to save our environment, it is a must that we develop new alternative refrigeration technologies like thermo acoustic refrigeration system, avoiding environmentally hazardous refrigerants. In this study, a thermo acoustic refrigerator (TAR) uses sound waves to provide cooling. Here the device is designed, consisting of a acoustic wave generation device regulated to the channel of a hollow tube, with a stack at a predetermined position in the channel of the tube. From the acoustic wave generation device, an acoustic wave emitted, achieving a temperature gradient across the stack.
