✦ Synopsis

This paper presents a detailed thermodynamic analysis of the working process of an active valve pulse tube refrigerator which is introduced to enhance the performance of a single stage pulse tube refrigerator. With the aid of several simplifying assumptions, the theoretical refrigeration power and coefficient of performance of this kind of refrigerator are obtained. Simulation results illustrate that the values of two intermediate pressures play a significant role in the system performance.
