The thermoacoustic energy conversion systems can operate as heat pumps (or refrigerators which are based on the same principle) or prime movers. The design optimization of the thermoacoustic refrigerator was made using two methods, namely the optimization based on the cooling load maximization and on the coefficient of performance (COP) maximization. The highest COP can be achieved with the noble gas mixture helium-xenon (62%-38%) as the working fluid, while the highest cooling load can be achieved with pure helium.
