Development and validation of a finite element model for water - CO2 coaxial gas-coolers

Sanchez, D.; Cabello, R.; Llopis, R.; Torrella Alcaraz, Enrique (Elsevier, 2012-05)

The gas-cooler heat exchanger is a characteristic device of the refrigeration plants that use CO2 as the working fluid in transcritical conditions. The proper gas-cooler sizing, allows getting the maximum effectiveness in ...
Energetic evaluation of a CO2 refrigeration plant working in supercritical and subcritical conditions

Sánchez, Daniel; Patiño, Jorge; Sanz Kock, Carlos; Llopis, Rodrigo; Cabello, Ramón; Torrella Alcaraz, Enrique (Elsevier, 2014-05)

Unlike other refrigerants, R744 (or carbon dioxide) has a very low critical temperature (30.98 C) which hampers working in subcritical conditions especially when the environment is used as a heat rejection sink. ...
Experimental evaluation of the energy efficiency of a CO2 refrigerating plant working in transcritical conditions

Cabello, R.; Sanchez, D.; Llopis, R.; Torrella Alcaraz, Enrique (Elsevier, 2008)

[EN] This work presents the experimental evaluation of the energy efficiency and optimal gas-cooler pressures of a single-stage refrigerating plant working with carbon dioxide as refrigerant in transcritical conditions. ...
