The invention relates to the technical field of thermo-acoustic engine systems, and discloses a loop thermo-acoustic drive combined cooling, heating and power system structure. The loop thermo-acoustic drive combined cooling, heating and power system structure comprises at least three thermo-acoustic units. The thermo-acoustic units are connected end to end through resonatrons to form a closed loop. Each thermo-acoustic unit comprises a thermo-acoustic engine, a linear motor and a refrigerating machine, all of which are sequentially connected in series. In the thermo-acoustic engine in the last thermo-acoustic unit, a backheating structure is used for generating acoustic power, the linear motor is used for consuming the first part of acoustic power, the refrigerating machine is used for consuming the second part of acoustic power, a heat exchange structure in the thermo-acoustic engine, a pipeline between the thermo-acoustic engine and the linear motor, a pipeline between the linear motor and the refrigerating machine and the resonatrons are used for consuming the third part of acoustic power together, and the thermo-acoustic engine in the next thermo-acoustic unit receives the fourth part of acoustic power. The loop thermo-acoustic drive combined cooling, heating and power system structure has the advantage of ensuring normal and efficient running of a complete machine.
Description
technical field [0001] The invention relates to the technical field of thermoacoustic engine systems, in particular to a loop thermoacoustic drive cogeneration system structure. Background technique [0002] A thermoacoustic engine is a new type of heat engine that uses the thermoacoustic effect to convert heat energy into sound work. When a thermoacoustic engine is coupled with a linear motor, the sound work can be further converted into electrical energy. When a thermoacoustic engine is coupled with a refrigerator or heat pump, Using sound power to carry heat can realize combined cooling and heating. [0003] The high sound power output of the thermoacoustic engine makes the engine have a surplus of sound power in addition to the cogeneration of cooling, heating and power when the engine is coupled with a refrigerator and a linear motor or a heat pump and a linear motor. At present, this scheme adopts a bypass connection A loop thermoacoustic drive cogeneration system str...
