One of common applications of thermoacoustic (TA) technology is cold production in a TA device powered by any heat source. This concept, based on combination of TA-engine and TAheat pump operating on different temperature ranges, allows conversion of heat directly into cold, using an acoustic wave as an energy carrier in between. Unlike electricity generation, heat powered thermoacoustic cooler needs no moving parts by the acoustic side. The solar and waste heat recovery in range of 70-200°C, so far, seems to be the most competitive to conventional systems (possible) TA application [1]. Reaching the satisfying efficiency by such low temperature is possible due to the idea of multistage devices. Connecting more regenerators in series enables decrease of the onset temperature, while the exergetic efficiency of 40% is still possible to achieve [2].
