A study on the cycle characteristics of an auto-cascade refrigeration system
Experimental Thermal and Fluid Science, 2009Abstract This study presents experimental results on the cycle characteristics of an auto-cascade refrigeration system. The auto-cascade refrigeration (ACR) system is driven by a single compressor, using zeotropic mixture as refrigerant, which achieves cascade between high and low boiling point components by an evaporative condenser for the purpose ...

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.
