Advanced two-stage cascade configurations for energy-efficient –80 °C refrigeration
Elsevier (2022-06-24)In response to the COVID-19 pandemic, some vaccines have been developed requiring ultralow-temperature refrigeration, and the number of these freezers has been increased worldwide. Ultralow-temperature refrigeration operates ... -
Conversion of a direct to an indirect commercial (HFC134a/CO2) cascade refrigeration system: Energy impact analysis
Elsevier (2017)Energy impact of conversion of a direct HFC134a/CO2 cascade refrigeration system to an indirect HFC134a-secondary fluid / CO2 cascade for commercial applications is experimentally analysed. Refrigeration systems, fully ... -
Effects caused by the internal heat exchanger at the low temperature cycle in a cascade refrigeration plant
Elsevier (2016)This work analyses and quantifies the effects caused by the use of an internal heat exchanger (IHX) at the CO2 subcritical cycle in an HFC134a/CO2 cascade refrigeration plant that incorporates a gas-cooler at the exit ... -
Energy and environmental comparison of two-stage solutions for commercial refrigeration at low temperature: Fluids and systems
Elsevier (2015-01-15)International agreements will restrict in the near future the use of high-GWP refrigerants in Europe. These restrictions will favour the implantation of refrigeration systems with low-GWP fluids, especially in applications ... -
Energy Evaluation of Multiple Stage Commercial Refrigeration Architectures Adapted to F-Gas Regulation
MDPI (2018-07-23)This work analyses different refrigeration architectures for commercial refrigeration providing service to medium and low temperature simultaneously: HFC/R744 cascade, R744 transcritical booster, R744 transcritical ... -
Experimental evaluation of an Internal Heat Exchanger in a CO2 subcritical refrigeration cycle with gas-cooler
Elsevier (2015-04-05)We present the experimental evaluation of an internal heat exchanger or suction-line/liquid-line heat exchanger in a CO2 subcritical refrigeration plant with gas-cooler. The plant, driven by a 1.5kW CO2 semi hermetic ...
