建立包含直线过程的热声制冷微循环模型,简要描述了热声微循环过程. 应用有限时间热力学的方法分析此模型的循环最优性能,求出了包含直线过程的热声微循环吸热与放热的临界点、循环的制冷量、制冷率及制冷机的性能系数;并由数值模拟得出热声制冷微循环中,制冷量、制冷率以及制冷机性能系数与直线过程压强比和等压过程体积比之间的特性关系. 结果表明:制冷机的制冷量随着等压过程体积比的增大而增加;等压过程体积比给定的条件下,直线过程压强比越小的制冷机获得的制冷量就越大;适当的压强比或体积比可以有效的提高制冷机的性能系数.

A thermoacoustic refrigeration micro-circle model with the straight line process was established and the process of thermoacoustic micro-circle was described briefly. The optimal performance of micro-circle was analyzed by using the finite time thermodynamics. The critical point of endothermic and exothermic, the refrigeration capacity, the refrigeration rate and refrigerator performance coefficient were calculated. The relationship between the refrigeration capacity, refrigeration rate and performance coefficient of refrigerator with the pressure ratio of straight line process and the volume ratio of isobaric process was obtained by using the numerical simulation. The results show that the cooling capacity increases with the volume ratio rising in isobaric process;the smaller pressure ratio of the refrigerator will obtain more refrigeration capacity at the given volume ratios of isobaric process; appropriate pressure ratio or volume ratio can improve the performance of the refrigeration.
