Introduction



Thermoacoustics combines the branches of acoustics and thermodynamics together to move heat using sound.
Acoustics is primarily concerned with the macroscopic effects of sound transfer like coupled pressure and motion oscillations.
Thermoacoustics focuses on the microscopic temperature oscillations that accompany these pressure changes.



Basic Principle


Thermoacoustics is based on the principle that sound waves are pressure waves and they propagate causing compressions and rarefactions in the medium.



Advantages


Harmful chemicals like CFC’s, HFC’s, HCFC’s are not released into atmosphere.
As the working fluid is an inert gas there is no toxicity, flammability, or negative environmental effects.
It is more reliable as there are few moving parts.


Conclusion


Thermoacoustic refrigeration is an innovative alternative for cooling that is both clean and inexpensive. The refrigeration effect is achieved by using sound waves and an inert gas which will not cause any damage to the atmosphere

A thermoacoustic refrigerator (TAR) is a refrigerator that uses sound waves to provide cooling. In a TAR, the working fluid is a mixture of helium-argon, and the compressor is replaced by a speaker. The advantages of this type of refrigeration cycle are twice.
• Helium and argon are inert, environmentally friendly gases, unlike many common refrigerants.
• The speaker is a simple device that is more durable than a compressor and is the only moving part of the TAR.
The disadvantage of ART is that, however, these types of refrigerators have failed to achieve efficiencies as high as standard refrigeration units. Some researchers claim that the ART startup is such that it will never be able to achieve efficiencies as high as standard cooling units. Others believe there is no reason why a TAR can not achieve efficiencies as high as standard refrigeration units. They attribute the currently lower efficiencies to the peculiar sensitivity of TAR to input parameters and the relative youth of the field in general.
