A review of the cascade refrigeration system

, 2020
This paper provides a literature review of the cascade refrigeration system (CRS). It is an important system that can achieve an evaporating temperature as low as −170 °C and broadens the refrigeration temperature range of conventional systems.

Experimental study on the pull-down performance of a −80°C cascade refrigeration freezer

, 2023
To cope with global climate change, chlorofluorocarbons and hydrofluorocarbons refrigerants have been or will be abandoned by different countries worldwide. Natural refrigerants seem to be promising substitutes in the near future.

Effect of mixed refrigerant composition on performance of an auto-cascade refrigeration system using R600a/R1150/R14

Thermal Science
A mathematical model based on energy and exergy methods is established to analyze the performance of an auto-cascade refrigeration system at varying compositions of the mixed refrigerants, condensation temperature, evaporation temperature, and vapor quality at the condenser outlet.

Advancing Hybrid Cryogenic Natural Gas Systems: A Comprehensive Review of Processes and Performance Optimization

Energies
Recent research in the liquefied natural gas (LNG) industry has concentrated on reducing specific power consumption (SPC) during production, which helps to lower operating costs and decrease the carbon footprint. Although reducing the SPC offers benefits,

Study on a Novel Absorption Referigeration System at Low Cooling Temperatures

, 2012
A novel absorption refrigeration system is proposed in this context using R134a+R23 mixed refrigerants and DMF solvent. The new system uses two-staged absorber in series to reduce the evaporation pressure and can obtain a lower refrigeration temperature ...
