Alternative refrigerants and refrigeration cycles for domestic refrigerators [PDF]

open access: yes, 1992
This project initially focused on using nonazeotropic refrigerant mixtures (NARMs) in a two-evaporator refrigerator-freezer design using two stages of liquid refrigerant subcooling. This concept was proposed and tested in 1975. The work suggested that the concept was 20% more efficient than the conventional one-evaporator refrigerator-freezer (RF ...

Blade design and analysis of centrifugal compressors for the transcritical carbon dioxide refrigeration cycle

open access: yesCase Studies in Thermal Engineering, 2023
The compressor is one important component in the transcritical CO2 (carbon dioxide) refrigeration cycle. The CO2 compressor has a small volume at the same refrigeration capacity because its refrigeration capacity per unit volume is large.
