Alternative blends of CO2 for transcritical refrigeration systems. Experimental approach and energy analysis
Sánchez García-Vacas, Daniel; Vidan-Falomir, Francisco; Nebot-Andres, Laura; Llopis, Rodrigo; Cabello López, Ramón Elsevier (2023-02-10)As a natural refrigerant, Carbon Dioxide (CO2) has been extended in almost all refrigeration fields due to its environmental friendliness, high availability, and high technological development in the main components of the ... -
Alternative CO2-based blends for transcritical refrigeration systems
Sánchez García-Vacas, Daniel; Vidan-Falomir, Francisco; Larrondo Sancho, Rafael; Llopis, Rodrigo; Cabello López, Ramón Elsevier (2023-03-21)The extensive use of CO2 in commercial refrigeration system has grown in the last two decade thanks to the development of new components and configurations that allows working in transcritical conditions efficiently. ... -
Characterization of thermal contacts between heat exchangers and a thermoelectric module by impedance spectroscopy
Beltrán-Pitarch, Braulio; Vidan-Falomir, Francisco; García-Cañadas, Jorge Elsevier (2019)Heat to electricity energy conversion efficiency of a thermoelectric (TE) device is not only influenced by the TE materials properties, but it also depends on the temperature difference between both sides of the TE legs. ... -
Defect governed zinc-rich columnar AZO thin film and contact interface for enhanced performance of thermocouples
Luo, Bingwei; Cao, Lili; Zhang, Jinyang; Fei, LUO; Zhou, Haitao; Kexin, Ma; Beltrán-Pitarch, Braulio; Solis de la Fuente, Mauricio; Vidan-Falomir, Francisco; García-Cañadas, Jorge Royal Society of Chemistry (2022-03-01)The research on the stable thermoelectric properties and contact interface of high-precision thin-film thermocouples lags far behind the demand. In this study, a zinc-rich Al-doped ZnO (AZO) thin film was fabricated, in ... -

Experimental evaluation of the CO2-based mixtures CO2/R32, CO2/R1234yf and CO2/R1270 in a transcritical refrigerating plant considering the effect of the internal heat exchanger (IHX)
Sánchez García-Vacas, Daniel; Larrondo Sancho, Rafael; Vidan-Falomir, Francisco; Cabello López, Ramón Elsevier (2024-01-05)Using CO2 mixtures results in a simple but effective solution to increase the critical temperature of CO2 and reduce its working pressures. However, the overall effect of these mixtures on the global performance of the ... -
Power factor improvement in a solid–liquid thermoelectric system formed by Sb:SnO2 in contact with a chromium complex solution
Castro Ruiz, Sergio; Márquez García, Lourdes; Solis de la Fuente, Mauricio; Beltrán-Pitarch, Braulio; Mota-Babiloni, Adrián; Vidan-Falomir, Francisco; Íñigo-Rabinal, P.; Guisado-Barrios, Gregorio; García-Cañadas, Jorge Royal Society of Chemistry (2023)Thermoelectric (TE) materials can convert heat into electricity. Good TE materials should have high power factors (PF) and low thermal conductivities. PF = S2σ is governed by the Seebeck coefficient S and the electrical ... -
