Résumé

This paper presents performance measurements of a carbon dioxide two-stage reciprocating compressor system using a hot-gas bypass load stand. The experimental data collected was used to characterize the compressors’ performance and evaluate oil management between the two compressors. A closed loop compressor load stand has been redesigned to conduct the compressor performance tests. Two hermetic reciprocating compressors, including two oil separators, two intercooling fans, and safety control valves, were connected to the load stand for testing. The first series of compressor tests were conducted for varying suction pressures and discharge pressures. In a second series of tests, the running time was varied and the suction pressure kept constant. Based on the acquired test measurements, compressor performance metrics, such as the volumetric and overall isentropic efficiencies, have been determined. Furthermore, compressor initial clearance factors were calculated, based on available compressor maps, which could be useful for future carbon dioxide system modeling. Also, a simulation model to predict two-stage compressor performance is presented. The entire process can be simulated to provide compressor performance data for different working conditions. Finally, the predicted performance was validated using the acquired test data.
