The travelling wave thermoacoustic refrigerator (TWTR), designed by a research team at Tokai University, consists of three etched stainless steel mesh regenerators installed within the prime mover loop and one in the refrigerator loop.
The team's progress was detailed in a paper, "Performance of a Small Low-Lift Regenerator-based Thermoacoustic Refrigerator," at the First Pan-American/Iberian Acoustics Meeting in Cancun, Mexico on Dec.
The heat transfer is then harnessed through heat exchangers on either side of this "stack." In this project, a Thermoacoustic refrigerator was manufactured from everyday materials including plexiglass, PVC piping and a loudspeaker.
The team's progress is detailed in a paper, "Performance of a Small Low-Lift Regenerator-based Thermoacoustic Refrigerator," released in early December at the First Pan-American/Iberian Acoustics Meeting in Cancun, Mexico.
A thermoacoustic refrigerator, Garrett said, is a resonator cavity that
Using this system, Garrett's group has fashioned a cube-shaped unit that will become the prototype for a household thermoacoustic refrigerator, he reported this week in San Francisco at the annual meeting of the American Association for the Advancement of Science.
Thermoacoustic refrigerators have been or are now being developed for a variety of purposes, such as cooling medical supplies, tropical fruit cargo, and seismic instruments in the earth's crust, as well as for liquefying natural gas.
