Experimental Investigation of Thermodynamics of High-speed Turbo-expander Refrigerator
Applying air-bearings supporting structure to the compressor turbine expander refrigeration system
the thermodynamic parameters of the test equipment was analyzed by means of system performance experimental investigation. The experiment results show that when the refrigerator rotating speed runs from 40000 r/min to 60000 r/min
the refrigerating performance improved greatly; the flow rate at 60000 r/min was twice as much as that at 40000 r/min
the temperature difference of the compressor and the turboexpander were doubled
while the power was increased five times as much. This test results provided reference_articles to the advanced optimization of compressor turbine expander.
