Summary

The first and second law of thermodynamics was used to analyze the orifice type and the double-inlet type of pulse tube refrigerator(PTR). Detailed dynamic characteristics of the thermodynamics, flow and heat transfer processes in the PTR were revealed, including thedynamic pressure variations, transient gas temperature, mass flow rate in the PTR. The exergy loss method was used to analyze eachcomponent in the PTR for the first time, and the performance coefficients of all components of PTR have been obtained. It was found that the performance coefficient of the double-inlet PTR was 0.108, 9% higher than that of the orifice PTR. The analysis also showed that the exergy efficiency of the double-inlet PTR was 29.95%, significantly higher than that of the orifice PTR (25.04%). In addition, it was found that the exergy losses in the regenerator and orifice were substantially larger than in other components of the PTR system. The optimal design of these two key components is, therefore, essential for the further improvement of the PTR performance. [Reprinted with permission from Elsevier. Copyright, 2006].
