This paper focuses on a 1 kW-class looped three-stage thermoacoustically-driven cryocooler operating at liquefied natural gas temperature. In this configuration, three identical thermoacoustic engines and one pulse tube cooler are connected by different-diameter resonance tubes. Based on thermoacoustic simulation program, the integral system is designed to achieve high efficiency and large cooling...
This paper introduces a novel, looped, thermoacoustically-driven cryocooler, which is a promising candidate for natural gas liquefaction applications. Several thermoacoustic heat engines of different diameters are connected end-to-end by small-diameter resonance tubes. One pulse tube cooler is connected to the branch of the last-stage engine. This system is highly reliable, efficient, and compact...
With increasing demand for liquefied natural gas, high-efficiency and compact facilities are vital for dealing with natural gas liquefaction or boiled-gas recondensation. This study introduces a looped multiple-stage thermoacoustically-driven cryocooler system that operates in the temperature range of natural gas liquefaction and which has good prospects for meeting such demand. Because of the looped...
