The results of numerical models and optimizations for various configurations of thermoacoustic refrigerators will be presented. The refrigeration goals are large-scale refrigeration with low temperature span, high efficiency, and reasonably high power density. The physical equations used are the usual plane wave Rott formulation with improved solutions for the heat exchangers and shaped resonator ducts. The primary emphasis will be on solutions having the highest system efficiency, excluding losses associated with electrical drivers and secondary heat exchange.
