A Quantum Analysis Model for the Irreversible Thermoacoustic Refrigerator Under the Condition of Weak Gas Degeneracy

The performance of the micro thermoacoustic refrigerator under the condition of weak gas degeneracy is studied, and a new analysis model for an irreversible quantum thermoacoustic refrigerator is established in this paper. Based on quantum statistics and thermodynamics theory, some important performance parameters of the thermoacoustic refrigerator such as the dimensionless cooling rate and the Coefficient of Performance (COP) are derived with the new model. Through numerical examples, the method to optimize the performance by adjusting some operation or structure parameters is given. At the same time, a new method to select the length of the regenerator is also found.
