Abstract

Abstract: Since the invention of the pulse tube refrigerator, improvements have mainly focused on developing new phase shifters, while the basic structure of the cold head is not changed much. With the combining of step piston pulse tube refrigerator with thermoacoustic refrigerator, a new concept called resonator pulse tube machine is proposed. It is investigated by a numerical simulation, which shows that it can work as a refrigerator or a cold engine depending on the swept volume ratio of the step piston compressor. Highlights: A new concept of a pulse tube refrigerator is introduced. It is a combination of a pulse tube refrigerator and a thermoacoustic refrigerator. It can be operated as a refrigerator and cold engine. High efficiency range is near to the critical swept volume ratio.
