Thermoacoustic heat pump

Thermoacoustic heat pumps can be applied in the industry to upgrade industrial waste heat. The thermoacoustic heat pump consists of a regenerator flanked by two heat exchangers and is usually placed in a gas filled acoustic resonator. An acoustic wave forces the working gas in the regenerator to undergo a Stirling Cycle and to pump heat from the low temperature heat exchanger to the high temperature heat exchanger.

The advantage of the thermoacoustic heat pump is that it can operate over a large range of  temperatures and can achieve large temperature lifts. One of the industrial applications where the application of the thermoacoustic heat pump can be beneficial is in distillation.
