  • Thermoacoustic refrigeration device and method
    Patent number: 6688112
    Abstract: A thermoacoustic refrigeration device employs a gas-vapor mixture as the working fluid. As a result, the refrigeration device operates according to a modified thermoacoustic refrigeration cycle that adds a condensation-vaporization cycle to the thermoacoustic cycle. The resulting modified refrigeration cycle increases the efficiency of heat transport by harnessing the translational motion of the vapor, as well as the usual acoustic oscillations, to transport the heat energy from one end of a thermal stack to the other.
    Type: Grant
    Filed: October 23, 2002
    Date of Patent: February 10, 2004
    Assignee: University of Mississippi
    Inventors: Richard Raspet, William V. Slaton, Craig J. Hickey, Robert A. Hiller, Henry E. Bass
