Energetic evaluation of a CO2 refrigeration plant working in supercritical and subcritical conditions
Sánchez García-Vacas, Daniel; Patiño Pérez, Jorge; Sanz Kock, Carlos; Llopis, Rodrigo; Cabello López, 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. Accordingly, ... -
Experimental analyis of energy performance of modified single-stage CO2 transcritical vapour compression cycles based on vapour injection in the suction line
Sánchez García-Vacas, Daniel; Cabello López, Ramón; Patiño Pérez, Jorge; Llopis, Rodrigo; Torrella Alcaraz, Enrique Elsevier (2012-12)This work presents the experimental evaluation of the energy performance of a modified single-stage CO2 transcritical refrigeration plant with an internal heat exchanger (IHX) based on vapour injection in suction line. ... -
Experimental evaluation of HCFC-22 replacement by the drop-in fluids HFC-422A and HFC-417B for low temperature refrigeration applications
Llopis, Rodrigo; Cabello López, Ramón; Sánchez García-Vacas, Daniel; Torrella Alcaraz, Enrique; Patiño Pérez, Jorge; Sánchez, J. G. Elsevier (2011-05)The Regulation CE-1005/2009 has banned the use of virgin HCFC-22 in Europe from the 31st December 2009, because it contains chlorine, although its use is allowed up to the 31st December 2014 if it is recycled. Now, ... -
Experimental Evaluation of the Energy Performance of an Air Vortex Tube when the Inlet Parameters are Varied
Torrella Alcaraz, Enrique; Patiño Pérez, Jorge; Sánchez García-Vacas, Daniel; Llopis, Rodrigo; Cabello López, Ramón Bentham Open (2013)he paper presents the analysis of the energy performance of an air vortex cooling tube under variations of the air inlet properties, with t hree independent experimental tests validated through the energy balance ... -

La estructura seguida se ... -
New positions for an internal heat exchanger in a CO2 supercritical refrigeration plant. Experimental analysis and energetic evaluation
Sánchez García-Vacas, Daniel; Patiño Pérez, Jorge; Llopis, Rodrigo; Cabello López, Ramón; Torrella Alcaraz, Enrique; Vicente Fuertes, Fernando Elsevier (2014-02)IHX is probably, one of the most commonly alternative used to improve cooling capacity and COP in a CO2 refrigerating plant working in supercritical conditions. The “classical” position at gas-cooler exit has been analyzed ...
