Abstract

In thermo-acoustic equipment carried out direct and reversible thermodynamic cycles are used non-stationary processes taking place in their heat-exchange devices, stacks and regenerators. An acoustic vibration generator with a flexible frequency and amplitude operation control is necessary for a thermo-acoustic refrigerator (TAR) research. It is informed about the creation of a generator on the base of a magneto-electric engine. A prototype pattern of TAR implements a classical cycle with a standing wave. At TAR testing the optimal operation frequency (101,7 Hz) to which corresponds the highest possible temperature reduction of helium in a regenerator (it is 14 °C ) was experimentally found. The basic tasks of further studies on TAR improving were stated.
