Résumé

In this paper, the frequency characteristic of loudspeaker-driven thermoacoustic refrigerator (TAR) and the influence factors wereinvestigated theoretically and experimentally. Experimental results under different conditions show that a narrow transmission frequencyband of TAR exists to generate strong oscillation and cause significant thermoacoustic effect, and TAR achieves optimum performance at the resonance frequency. The frequency characteristic is determined by combined network elements of TAR. Then the analytical model was built to validate the experimental results. It provides a coupling method for design of loudspeaker-driven TAR system. [Reprinted with permission from Elsevier. Copyright, 2005].
