摘要

在考虑热漏、热阻及不可逆因子等因素的情况下,建立复指数传热规律的不可逆热声制冷机循环模型.以热声制冷机输入功率P,系统输出率A,系统不可逆损失率Q,制冷率R构建多目标函数,采用线性加权评价函数法求解,分析多目标函数与各参数的优化关系,得出多目标优化可以较好地协调各性能指标间关系的结论.
        A cycle model generalized irreversible thermoacoustic refrigerator with complex exponential heat transfer was built by using finite-time thermodymamics in which heat resistance heat leakage and internal dissipation were considered. We construct multi-objective function using thermoacoustic refrigerator input power P,system exergy output rate A,system irreversible loss rate Q,cooling rate R. And the optimal performance of the system by using the linear weighted evaluation function method. The results show the optimization relationship between multi-objective function and each parameter,and conclude that multiobjective optimization can better coordinate the relationship of each performance index.
