Abstract
A regenerative thermo-acoustic energy converter includes a regenerator assembly located within an acoustic resonator room filled with gas, the regenerator assembly includes a regenerator located between a cold heat exchanger and a warm heat exchanger and a non-dissipative bypass circuit filled with gas connected across the regenerator assembly.
Claims8
A thermo-acoustic energy converter, comprising:
- a acoustic resonator room filled with a gas, the gas creating a gas pressure in the room;
- a regenerator assembly within the acoustic resonator room, the regenerator assembly comprising
- a regenerator,
- a cold heat exchanger arranged adjacent a first side of the regenerator, and
- a warm heat exchanger arranged adjacent a second side of the regenerator;
- and
- a non-dissipative bypass circuit filled with the gas, the non-dissipative bypass circuit connecting one side of the regenerator assembly with another side of the regenerator assembly, the non-dissipative bypass circuit arranged to use an acoustic propagation delay or an inertance of the gas to create in the regenerator a gas velocity in phase with the gas pressure of the acoustic resonator room.

A thermo-acoustic system, comprising:
- a first acoustic resonator room filled with a gas, the gas creating a gas pressure in the first room;
- a first regenerator assembly within the first acoustic resonator room, the regenerator assembly comprising:
- a first thermo-acoustic energy converter having
- a first regenerator, and
- two heat exchangers, a cold heat exchanger arranged adjacent a first side of the first regenerator, and a warm heat exchanger arranged adjacent a second side of the first regenerator;
- a non-dissipative bypass circuit filled with the gas, the non-dissipative bypass circuit connecting one side of the first regenerator assembly with another side of the first regenerator assembly, the non-dissipative bypass circuit arranged to use an acoustic propagation delay or an inertance of the gas to create in the first regenerator a gas velocity in phase with the gas pressure of the first acoustic resonator room;
- and
- a second thermo-energy converter having
- a second resonator room with a second regenerator assembly,
- the second resonator room coupled to the first resonator room,
- the second thermo-energy converter being essentially identical to the first thermo-energy converter,
- the first thermo-energy converter being arranged to supply heat to one of the first converter's two heat exchangers and drain heat from the other of the first converter's two heat exchangers, and
- the second thermo-energy converter being arranged as a heat pump driven by the first thermo-energy converter so that heat from one of the second converter's two heat exchangers is pumped into the other of the second converter's two heat exchangers.
