Breadboard development of a hydraulically coupled Free Piston Stirling Engine heat pump compressor
For more than a decade the Free Piston Stirling Engine (FPSE) has been considered as an attractive candidate for a thermally activated heat pump because of its potential for high efficiency coupled with long life and high reliability. The distinguishing features of the FPSE, one moving part and hermetic separation of the power cycle and refrigeration cycle working fluids, makes it ideally suited for a heat pump application. However, two major design challenges have kept the FPSE in the realm of laboratory rather than product development. Specifically, these challenges involve; effective control of a tuned resonant system over a wide range of loads and hermetic coupling of the driver and driven mechanical members. 8 figs., 1 tab.
