Summary

The primary function of a thermal acoustic driver (TAD) is the production of cold due to the transformation of acoustic energy into heat and its removal of a thermodynamic system. An experimental TAD model consisting of a half-wave TAD that generates highly potential acoustic energy and a refrigerator transforming acoustic energy into heat has been studied in the paper. The power balances of the installations that include TAD operating at various modes and at the change of some elements (stacks) layout in an experimental model have been made. The dependences of the efficiency coefficient, sound pressure and oscillation frequency at various modes of filling a driver with such gases as helium, nitrogen, argon, krypton, and sulphur hexafluoride have been determined. Such devices can be applied in the installations that have sources of nonrecuperated heat, for example, in the installations for the inert gas production that use catalytic hydrogenation for the purification of a crude neon-helium mixture from hydrogen; some superfluous quantity of heat is produced at hydrogen incineration A part of the heat generated during this process can be used for the TAD operation; it will increase the thermodynamic efficiency of the installation This paper can be useful for people engaged in the research and design of refrigeration engineering and TAD.
