โฆ Synopsis
This paper presents the test results of the internal process of a double inlet pulse tube refrigerator, the main objective is to reveal the effects of some important parameters , such as by-pass valve and orifice opening, operating frequency and mean pressure, on the amplitude shift and phase shift of three dynamic pressures at three different points (the hot end of the regenerator, pulse tube and reservoir)

This paper describes experimental results on the double-inlet pulse tube refrigerator. The effects of varying the amplitudes and phase difference of the pressure wave and mass flow are presented and discussed.
A two-stage pulse tube refrigerator in combination with a rotary valve and a valved compressor has been constructed. Its performance and the effects of the operating parameters were investigated. A minimum temperature of 11.5 K and a cooling capacity of 1.3 W at 20 K were obtained at a frequency of
The pulse tube reported in this paper is 5 mm in inner diameter and 50 mm in length with an effective tube volume of about 0.4cm3. The coaxial design is used to minimize its dimensions and nylon tube is used to decrease heat transfer between the pulse tube and the surrounding regenerator. It was op
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
This paper describes experiments comparing a commercial available R134a refrigeration plant subjected to a cold store and a prototype R744 (carbon dioxide) system working as a classical 'split-systems' to cool air in residential applications in a transcritical cycle. Both plants are able to develope
