Thermoacoustic refrigeration is an environmental friendly technology as it uses gases like air, helium as a refrigerant. Its biggest advantage is that they do not use harmful gas as a refrigerant. It is pollutant free method of providing refrigeration. It uses helium which is noncombustible, nonpoisonous inert gas having zero global warming effect. According to Montreal protocol which is international agreement signed by 165 countries to control the production and exchange of ozone depleting substances. It controls the import, export, manufacture, use, sale of any HCFC or product that contains or intended to contain HCFCs as this regulation comes in to play thermoacoustic refrigeration proves to be a green technology .As it does not contain any moving part other than speaker which increase the lifespan of product and decrease the maintenance cost. So it does not use lubricant. It only uses the sound wave which is pressure wave for cooling.The only disadvantage of this thermoacoustic 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.This paper is focuses on use of different gases with stacks of different materials and finding best suitable or optimum combination which gives higher value of c.o.p.
