ShareSummary
In order to improve the efficiency of the transcritical CO2 cycle, a new two-cylinder rolling piston expander was proposed. Compared with the traditional rolling piston expander the suction valve of this expander could be removed, and therefore the expansion process becomes continuous. Both of the reliability and performance of the expander could be improved. In order to analyze the work process and forces acting on main components, a mathematical model of this kind of expander was developed.
