Experimental study of the design optimization of a traveling-wave thermoacoustic refrigerator is described. The thermoacoustic refrigerator is composed of a looped tube and regenerator; the regenerator is located in the looped tube. The looped tube is connected to an acoustic driver via a connecting tube. The regenerator is composed of many narrow flow channels and works as an energy conversion component. The coefficient of performance (COP) of the traveling-wave thermoacoustic refrigerator was measured with varying the position of the regenerator and the radius of the narrow flow channels in the regenerator. It was found that the measured COP depends on both regenerator's position and radius and both of them have the optimum values for high COP. The reasons of the existence of the optimum regenerator's position and radius for high COP were addressed.
