Structural dynamic analysis of the orbiting scroll wrap in the scroll compressor

Yicai LIU, Yubo XIA, Peng YAN, Yinbin LI, Haibo XIE

Frontiers in Energy 2013, Volume 7, Issue 1, Pages 19-25 doi: 10.1007/s11708-012-0223-9

Abstract: A deep analysis of orbiting scroll wraps was conducted in this paper by using ANSYS and SolidWorks.Through the modal analysis, the involute of the circle profile orbiting scroll wrap demonstrated a largeanalysis, loads of frequency changes were gained and the stress and strain distribution of the orbiting scrollThe results of the present study offer a theoretical basis for the design and manufacture of scroll wraps, and providing a new way to evaluate different scroll wraps.

Simulation of the optimal heat rejection pressure for transcritical CO

Junlan YANG, Yitai MA, Minxia LI, Hua TIAN

Frontiers in Energy 2010, Volume 4, Issue 4, Pages 522-526 doi: 10.1007/s11708-010-0027-8

Abstract: maximum COP exists at the optimal heat rejection pressure not only for throttle valve cycle but also for expanderAlso, the optimal heat rejection pressures of the throttle valve cycle are greater than those of the expanderIn order to further obtain correlation of the optimal heat rejection pressure for transcritical CO expandercycle, it is necessary to analyze the impact degree of compressor efficiency, expander efficiency, gasBased on the simulation results, the values of the optimal heat rejection pressure for the expander cycle
