The team's progress will be detailed in a paper, "Performance of a Small Low-Lift Regenerator-based Thermoacoustic Refrigerator," Wed.
Garrett explains that his group's thermoacoustic chiller uses a souped-up loudspeaker to generate high amplitude sound energy in an environmentally safe gas--currently the air we breathe--that is converted directly into useful cooling.
We have been operating loudspeakers at resonance and using bellows in thermoacoustic devices for 20 years," Garrett adds.
This Earth Day, Ben & Jerry's announces the development of a working thermoacoustic refrigeration prototype - an environmentally friendly, alternative refrigeration technology that chills out to sound waves.
Thermoacoustic refrigeration uses sound waves at 173 decibels - many times louder than an average rock concert - instead of chemicals like HCFCs and HFCs to generate cooling.
The thermoacoustic refrigeration process has many benefits," said Dr.
The thermoacoustic chilling unit works much like a traditional refrigerator, except that it uses sound waves instead of a compressor to create cooling.
For a detailed, third-party account of the history and potential of thermoacoustics, read this American Scientist article, The Power of Sound.
Although this video does not show Cool Sound's advanced technology in action, the demonstration is still useful for understanding the principles behind thermoacoustics.
GDSI), Seeking To Harness The Game-Changing Potential In Thermoacoustic Technology For A Variety Of Commercial And Defense-Related Applications, Signs Exclusive Letter of Intent to Acquire Cool Sound Industries, Inc.
Frank Wighard, inventor and founder of CSI, holds a patent for a revolutionary double-acting thermoacoustic driver and says the power of sound waves can be harnessed to eliminate the use of dangerous ozone-depleting and global-warming chemicals used in air-conditioning systems and provide a way for them to comply with the new EPA and Montreal Protocol Regulations, which stop the production of chlorine-based refrigerants worldwide after January 1, 2015
