Abstract
A method for operating a thermoacoustic engine which produces acoustic energy which may be used to generate refrigeration wherein energy delivery fluid from a hot energy source, which provides heat to the thermoacoustic engine, is used to provide heat to a first heat sink such as a Kalina cycle and then at a lower temperature to a second heat sink.
Claims8
A method for employing heat energy comprising:
- (A) providing heat from a hot energy source to a thermoacoustic engine, and employing said heat in the thermoacoustic engine to produce acoustic energy;
- (B) using heat from the hot energy source to produce an energy delivery fluid having a temperature within the range of from 350 to 750° C., and cooling the energy delivery fluid to a temperature within the range of from 100 to 400° C. by providing heat from the energy delivery fluid to a first heat sink;
- and
- (C) passing the cooled energy delivery fluid to a second heat sink and providing heat from the cooled energy delivery fluid to the second heat sink.

A method for employing heat energy comprising:
- (A) employing heat from a hot energy source to produce hot energy delivery fluid having a temperature within the range of from 500 to 1200° C., and providing heat from the hot energy delivery fluid to a thermoacoustic engine to produce acoustic energy, said provision of heat resulting in the energy delivery fluid having a temperature within the range of from 350 to 750° C.;
- (B) cooling the energy delivery fluid to a temperature within the range of from 100 to 400° C. by providing heat from the energy delivery fluid to a first heat sink;
- and
- (C) passing the cooled energy delivery fluid to a second heat sink and providing heat from the cooled energy delivery fluid to the second heat sink.
