A new thermoacoustic refrigerator which is driven by a double-acting traveling-wave thermoacoustic engine have been researched and designed. Through numerical simulation
we optimize the structure parameters of the refrigerator. Under the design conditions
the new refrigerator reaches a COP of 2.74
a relative Carnot efficiency of 60%
a consumed P-V power of 534W
and a cooling capacity of 1464.9W. In addition
a traditional Stirling refrigerator and the new thermoacoustic refrigerator with double-action operation are calculated and compared for operating pressure ratio
efficiency
cooling capacity and other features
and the simulated results show that the new thermoacoustic refrigerator is very efficient and suitable for coupling with a double-action
traveling-wave thermoacoustic engine. Thermoacoustic refrigerator with double-action operation has good potential as an alternative of ordinary refrigeration technology due to intrinsic high efficiency heat driven mechanism
