PSU Gets Money to Work on Project that
Uses Sound to Power Air Conditioner

Penn State has received a federal grant to work on a project that will produce an air conditioning unit that recycles sound for cooling.

The Thermoacoustic Air Conditioner was one of 43 projects selected by the U.S. Department of Energy to receive money through the Department’s Advanced Research Projects Agency-Energy. The $2.9 million comes from American Recovery and Reinvestment Act funding.

The Penn State team plans to produce a 1-ton air conditioning unit that uses high amplitude sound and helium gas to recycle acoustical power for cooling.

The project will scale up an ice cream chiller built for Ben & Jerry’s that combined the acoustic power produced by high efficiency moving magnet linear motor with recycled power to produce useful cooling in a “bellows bounce” thermoacoustic chiller.
