| Abstract: | 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. |
