Performance assessment of an experimental CO2 transcritical refrigeration plant working with a thermoelectric subcooler in combination with an internal heat exchanger
(Elsevier, 2022)
Artículo / Artikulua,
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 ...
On the extension of k-ω-SST corrections to predict flow separation on thick airfoils with leading-edge roughness
(Wiley, 2023)
Artículo / Artikulua,
Modern wind turbines employ thick airfoils in the outer region of the blade with strong adverse pressure gradients and high sensitivity to flow separation, which can be anticipated by leading-edge roughness. However, ...
Experimental enhancement of a CO2 transcritical refrigerating plant including thermoelectric subcooling
(Elsevier, 2020)
info:eu-repo/semantics/article,
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 ...

Heat pipes thermal performance for a reversible thermoelectric cooler-heat pump for a nZEB
(Elsevier, 2019)
Artículo / Artikulua,
The nZEB standards reduce the energy demand of these buildings to a minimum, obtaining this little energy from renewable resources. Taking these aspect into consideration, a thermoelectric cooler-heat pump is proposed to ...
Experimental analysis of one and two-stage thermoelectric heat pumps to enhance the performance of a thermal energy storage
(Elsevier, 2023)
info:eu-repo/semantics/article,
This experimental study demonstrates the possibility to enhance the performance of a low-temperature thermal energy storage system (~160 ¿C) based on airflow heating using electrical heaters by including thermoelectric ...
Assessing the reliability of current simulation of thermoelectric heat pumps for nearly zero energy buildings: expected deviations and general guidelines
(Elsevier, 2019)
info:eu-repo/semantics/article,
This paper makes evident that a rigorous review of simulation methods for thermoelectric heat pumps in nearly-zero energy buildings is needed, as incoherent results during verification and validation of simulation models ...

Contribución a congreso / Biltzarrerako ekarpena,
The Chair of Women, Science and Technology of the Universidad Pública de Navarra (UPNA) aims to increase the participation of women in the fields of science and technology. Scientific culture and dissemination are the main ...
Experimental evaluation of a transcritical CO2 refrigeration facility working with an internal heat exchanger and a thermoelectric subcooler: performance assessment and comparative
(Elsevier, 2022)
Artículo / Artikulua,
The use of carbon dioxide in transcritical state has become one of the most used solutions to comply with the F-Gas directive and reduce greenhouse gases emissions from refrigeration systems at high ambient temperatures. ...
Experimental validation and development of an advanced computational model of a transcritical carbon dioxide vapour compression cycle with a thermoelectric subcooling system
(Elsevier, 2022)
Artículo / Artikulua,
The inclusion of a thermoelectric subcooler as an alternative to increment the performance of a vapour compression cycle has been proved promising when properly designed and operated for low-medium power units. In this ...
