Abstract
In a thermoacoustic refrigerator that refrigerates using exhaust heat, the configuration of resonant tubes that connect a thermoacoustic engine and a refrigerator has a dramatic effect on its efficiency. This research focused on a double loop type thermoacoustic refrigerator. Numerical analysis conducted on the relationship of the refrigerator loop and branch resonator length to find a relationship to efficiency. A refrigerator with specifications with the highest efficiency was created. The result was that the conversion efficiency from heat to cold heat reached 22.2%, verifying the validity of this numerical analysis method.
