| Abstract: | The exergoeconomic performance of the thermoacoustic referigeration micro-cycle model which only was accounted for the heat resistance between the working gas and the plates had been analyzed using finite time thermodynamics.The analytical formulae about the relations between the profit rate and the oscillating temperature,as well as between the profit and the COP were derived.The influences of the portrait temperature difference and the price ratio on the exergoeconomic performance are investigated by numerical examples. |
