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 efficiency utilization can not be increased at least at par with the traditional vapour compressor counterpart. The paper deals with the basic concept of thermo acoustic refrigeration, two working prototypes of thermo acoustic refrigerators, features, merits and demerits of thermo acoustic refrigeration..
