Optimization of a thermoacoustic apparatus based on operating conditions and selected user input

摘要

In a thermoacoustic refrigerator, operating temperatures, ambient temperature, and selected user input are utilized to control frequency and/or input power in order to optimize the efficiency of the thermoacoustic refrigerator operation. In a thermoacoustic heat engine, operating temperatures, ambient temperature, and selected user input are utilized to control impedance of a load to optimize the efficiency of the thermoacoustic heat engine operation.
