A thermoacoustic refrigerator is remarkable because it uses natural gas as a refrigerant and doesn't need a routine maintenance. Some experimental discussions and analysis have bee done, but there are few effective methods of system design of this refrigerator. In this paper, some results of performance tests of a loudspeaker-driven thermoacoustic refrigerator are discussed. In the investigation on the influence of stack type on the performance, a stack of parallel plate type is the highly efficient stack. From the result, some requirements exist for the stack configuration and some of them are listed. In conclusion, the cross-sectional shape of stack is needed to be the assembly of cells which have almost the same gap between solid walls, and the operating condition has a influential factor as well as the stack configuration does so.
