Cascaded superheat control with a multiple evaporator refrigeration system
Proceedings of the 2011 American Control Conference, 2011Variable refrigerant flow (VRF) systems are increasingly being used in commercial buildings in preference to chilled water or ducted air systems. The closely coupled dynamics of VRF systems, however, create a need for effective control strategies to ensure safe and effective operation.

Cascade refrigeration system synthesis based on exergy analysis
Computers & Chemical Engineering, 2011Abstract Refrigeration systems are very important to chemical/petrochemical process industries because their performances are closely related to product quality, energy usage efficiency, and plant profitability. Hitherto, the optimal synthesis of a cascade refrigeration system with multiple refrigerants and multiple temperature levels presents ...

Energy and exergy analysis of low GWP refrigerants in cascade refrigeration system
Energy, 2019Abstract In this paper, R23, R41 and R170 are used in the low-temperature cycle (LTC) and R32, R1234yf, R1234ze, R161, R1270, R290 and R717 are used in the high-temperature cycle (HTC) refrigerant in cascade refrigeration system (CRS). In order to evaluate the potential of refrigerant and find out which refrigerant couple performs better in CRS ...

APPLICATION OF CASCADE REFRIGERATION SYSTEM WITH MIXING REFRIGERANT IN COLD AIR CUTTING
International Journal of Modern Physics B, 2005In the mechanical cutting process, the replacement of traditional cutting solution with cold air can avoid the pollution of environment. In order to high efficient the refrigerating device and flexible adjust the temperature of cold air, it is necessary to use cascade refrigeration system to supply cool quantity for the compressed air.

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.
