Résumé
A turbo-expander is developed for the regeneration in the expansion process. The turbo-expander operates in the partial admission and supersonic flow, and an axial-type single stage turbine is applied to the turbo-expander. Its outer diameter is 82 mm and the operating gas is R-134a. A 15-kW reciprocating compressor is applied in the experiment and the turbo-expander is installed in the expansion process instead of the commonly using expansion valve. One supersonic nozzle is applied for the expansion process. The high speed of R-134a after passing the supersonic nozzles gives the impulse force to the turbo-expander and powers are generated on this process. A generator is installed at the end of the turbo-expander shaft. The generating output power from the turbo-expander is controlled by the power controller. Pressures and temperatures are measured on the refrigerant circulation lines of the experiment utility for the performance investigation. More than 150 W are generated in this experiment.
