摘要
采用热声压缩机驱动脉管制冷机将完全消除系统的机械运动部件 ,大大提高了运行的可靠性。随着热声驱动脉管制冷机研究的不断深入 ,人们迫切需要能真实反映系统效率的评价标准 ,文中给出三种评价方法 :(1 )系统的总效率 ;(2 )系统的相对卡诺效率 ;(3)系统的火用效率。建议采用火用效率对系统效率进行综合评价 。
Driving a pulse tube cooler by using thermoacoustic engine completely eliminates moving parts of refrigeration system, which leads to more reliable operation. People urgently need a reasonable evaluation standard that can really reflect the efficiency of such a complicated refrigeration system. Three standards, such as total efficiency; relative Carnot efficiency; energy efficiency are introduced and compared. Energy efficiency is recommended, which can provide instructive reference for the improvement and utility of thermoacoustic refrigeration systems.
