An Experimental Study on a Three-Temperature Three-Cylinder Stirling Cycle Machine

摘要

A new general three-temperature three-cylinder Stirling cycle machine designed by vector analysis reported before has been manufactured and experimented. The machine has three cylinders (Hot, Middle and Cold temperature) and the phase angle of the Hot piston can be changed between 80 and 160 degrees to the Middle piston. The measured performance and the P- V diagrams of each cylinder in various experiments are shown to agree well with the predicted values by vector analysis. Also, the change of performance of each cylinder by Hot piston phase change is qualitatively similar to the theoretical one. Moreover, applications of this kind of machine are reported.
