Abstract
The working principle of an efficient travelling-wave thermoacoustic refrigerator operating in room-tem-perature range has been analyzed and an experimental set-up has been built. The experiment showed that suppressing DC-flow streaming was very critical to efficient operation, and an elastic membrane was used to solve the problem successfully. At the most efficient operating point, the novel thermoacoustic refrigerator achieved a cooling capacity of about 80 W at −20°C, with a much higher efficiency than previously developed standing-wave thermoacoustic refrigerator.
