The experimental thermoacoustic device

The transition processes in the thermoacoustic heat pump are presented. The thermoacoustic heat pump was designed and build by “Thermoacoustic Technology Ltd” in cooperation with the ФГУП ГНП РКЦ «ЦСКБ-ПРОГРЕСС». The experimental thermoacoustic device may be used as a refrigerator, heat pump or an acoustic pulsator. It consists of the thermoacoustic engine, thermoacoustic refrigerator and the acoustic resonator. The work of the experimental device based on the direct and the reverse thermoacoustic effects. The direct thermoacoustic effect is the generation of the acoustic waves due the temperature gradient. The reverse thermoacoustic effect is the generation of the temperature gradient due the work of the acoustic waves. The thermoacoustic technology has many various applications at different branches of the science and technique.
