Thermo acoustic Refrigeration is based on the principles of creation of temperature gradient from sound waves and this theory was first developed in 1960s. Unlike vapour compression system, Thermo acoustic engines uses inert gases which is safe and no adverse effect on the atmosphere like the depletion of ozone layer and global warming.

Even though acoustic Refrigeration is efficient and cost effective its commercial application is warranted the need of more R&D efforts for technology up gradation and standardization without which its eff ....etc

Thermo Acoustic Engines

abstract

Environmental priorities are forcing chloro -fluorocarbons out of market place thereby creating a new demand for cooling technologies. This paper presents an outcome of researches done to design, construct and evaluate a CFC free refrigeration system. A prototype Thermo acoustic cooling system utilizing high amplitude sound waves in an inert gas is discussed.
