Abstract:Much research efforts and progress have been done on thermoacoustic refrigerators in past decades because they are environmentally benign, mechanically simple and highly reliable. In this article the design and manufacture of a traveling-wave thermoacoustic refrigerator in toroidal topology were given in detail. The driver of the refrigerator is a crank-shaft-rod compressor that is originally used for vapor-compression refrigeration cycle. We modified it to provide oscillating pressure wave and tried to separate the lubricant oil. In the initial test, the refrigerator achieved the cooling temperature of 264K with helium as the working gas. Other experimental details and experimental result were also reported in the paper.
Keywords:Traveling-wave  Thermoacoustic refrigerator  Electro-acoustic compressor  Room temperature
