The Thermoacoustic refrigerator is a machine which potentially can replace the current refrigerating devices in a large scale. One of the very foremost reasons for that is it is environment friendly. Also due to less moving parts it is very reliable and has a long life span. Conventional refrigerators use refrigerants to carry heat from lower temperature reservoirs to higher temperature reservoirs. The refrigerants generally used are CFC’s, ammonia etc., which are harmful to the environment. In Thermo-acoustic refrigerators these harmful CFC’s are not used which makes it eco-friendly. The term thermo-acoustic represents conversion heat energy into sound energy and vice versa. The basic working principle of this device depends on sound waves to generate pressure waves that will alternately expand and compress the gas particles within a tube. This will further lead to a cooling effect. The basic design outline, components and working principle of the thermoacoustic refrigerator are discussed in this paper.
