An improved numerical modelling technique for predicting the detailed performance and characteristics of an orifice pulse tube refrigerator has been developed. A variety of physical factors, such as gas flow friction, heat transfer in the heat exchanger and regenerator, real material properties etc.

## By applying the first law of thermodynamics for open systems to subvolumes of a four-valve pulse tube refrigerator, we have calculated its ideal cold generating process. The coefficient of performance increases for a decrease in the ratio of high to low pressure. In the limit of a pressure rati
The orifice pulse tube refrigerator has the potential to become a small, reliable cryocooler. In linear approximation the refrigeration produced is due to two independent contributions: an enthalpy flow in the bulk of the gas and an enthalpy flow due to heat exchange with the wall. These effects are
A third-order computer model has been developed by modifying the Stirling Refrigerator Performance Model (SRPM), which has been validated extensively by various Stirling refrigerators in the literature. The resulting computer program, known as the Pulse Tube Refrigerator Model (PTRM), has been valid
To investigate how to reach 4 K using a pulse tube and the best multiple staging configuration for the pulse tube, experiments were performed on several types of singlestage pulse tube refrigerators coupled with a Gifford-McMahon cryocooler. The minimum temperature obtained at the cold end of the pu
