Experimental assessment of a thermoelectric subcooler included in a transcritical CO2 refrigeration plan
Aranguren, Patricia; Sánchez García-Vacas, Daniel; Casi, Álvaro; Cabello López, Ramón; Astrain, David Elsevier (2022-05-25)This study brings an experimental research that has tested a real transcritical CO2 vapor compression cycle that includes a thermoelectric subcooler at the exit of the gas-cooler of the refrigeration plant. The aforementioned ... -
Experimental enhancement of a CO2 transcritical refrigerating plant including thermoelectric subcooling
Sánchez García-Vacas, Daniel; Aranguren, Patricia; Llopis, Rodrigo; Cabello López, Ramón; Astrain, David; Casi, Álvaro Elsevier (2020-09-02)CO2 is an excellent natural refrigerant that can be used in almost any commercial cooling application thanks to its useful range of evaporative temperatures and excellent environmental properties. However, due to its low ... -

Improvements in the cooling capacity and the COP of a transcritical CO2 refrigeration plant operating with a thermoelectric subcooling system
Astrain, David; Merino, A.; Catalán, L.; Aranguren, Patricia; Araiz, Miguel; Sánchez García-Vacas, Daniel; Cabello López, Ramón; Llopis, Rodrigo Elsevier (2019-06-05)Restrictive environmental regulations are driving the use of CO2 as working fluid in commercial vapour compression plants due to its ultra-low global warming potential (GWP100 = 1) and its natural condition. However, at ... -
Performance assessment of an experimental CO2 transcritical refrigeration plant working with a thermoelectric subcooler in combination with an internal heat exchanger
Casi, Álvaro; Aranguren, Patricia; Araiz, Miguel; Sánchez García-Vacas, Daniel; Cabello López, Ramón; Astrain, David Elsevier (2022-07-19)Regulations in the refrigeration sector are forcing the transition to low global warming potential fluids such as carbon dioxide in order to decrease direct greenhouse gases emissions. Several technologies have arisen over ...
