Equivalent Cycle and Optimization of Auto-Cascade Absorption Refrigeration Systems
Journal of Thermal Science, 2020Auto-cascade absorption refrigeration (ACAR) systems are a class of new cycles that can achieve low refrigeration temperatures by utilizing low-quality thermal energy. In this study, the equivalent thermodynamic processes of a reversible ACAR system are established, and illustrated in a T-s diagram. The formula of the coefficient of performance for the

Research on the Auto Cascade Refrigerating Cycle System
Advanced Materials Research, 2012An auto cascade refrigerating cycle system was built up in the laboratory. By changing the parameters of the operation process, the law of the operation and the effect on performance of the system were studied. When the extrinsic parameters changed, the performances of the system were measured.

Exergy analysis and parameter study on a novel auto-cascade Rankine cycle
Energy, 2012Abstract A novel auto-cascade Rankine cycle (ARC) is proposed to reduce thermodynamics irreversibility and improve energy utilization. Like the Kalina cycle, the working fluid for the ARC is zeotropic mixture, which can improve the system efficiency due to the temperature slip that zeotropic mixtures exhibit during phase change.
