Thermo-acoustic refrigeration is an environmental friendly technology. It is use as a working fluid like air or Noble gases as a refrigerant. Its biggest advantage is that they do not use harmful gas as a refrigerant and pollutant free method of providing refrigeration. For the safety of the environment, it is necessary to avoid the use of environmentally hazardous refrigerants by developing new alternative refrigeration technologies such as Thermo-acoustic Refrigeration System. This paper describes the variation of hot end temperature and the temperature difference between the different stack ends with the various parameters like frequency, mean pressure. This paper explored the basic principles of thermo acoustic refrigeration, combined with an understanding of the underlying thermodynamics, the model enables us to spread awareness of the visibility of thermo acoustic devices as refrigerator. Thermo acoustics is a field that combines thermodynamics, fluid dynamics and acoustics. In thermo acoustics it is possible to construct thermodynamic engines, prime movers and heat pumps which respectively use heat to create work and use work to create or move heat. The only disadvantage of this thermacoustic refrigeration is it has low C.O.P compare to other conventional cooler. But most efficient system are tried to be made. Lots of research is going on in this area.
