PURPOSE: A system for optimizing the operation of a heat audio device is provided to optimize the efficiency of a thermoacoustic refrigerator by controlling the frequency/ input voltage of a thermoacoustic refrigerator. CONSTITUTION: A thermoacoustic device comprises a body(72), a regenerator(74), a first heat exchanger(76), a second heat exchanger(78), an electro-mechanical driver(82), a temperature sensor(94), a controller(98) and a variable frequency driver(84). The body comprises a working gas. The regenerator is arranged within the body. The first heat exchanger is closely arranged at the regenerator in the first longitudinal end of the regenerator. The second heat exchanger is closely arranged at the second regenerator in the longitudinal end of the regenerator. The electro-mechanical driver sends the sound energy to the body inside. The temperature sensor measures the partial temperature of the thermoacoustic device and offers the temperature data signal. The variable frequency driver receives the control signal from the controller and the variable drive signal is offered to the electro-mechanical driver. |
