13th National and 4th International edition of the Conference on Engineering Thermodynamics: proceedings book
Cabello López, Ramón; Sánchez García-Vacas, Daniel; Nebot-Andres, Laura; Llopis, Rodrigo Universitat Jaume I (2023-12) -
Evaluation of zerotropic mixtures as refrigerants in a dedicated subcooling system of a CO2 refrigeration plant
Toffoletti, Gabriele; Nebot Andrés, Laura; Martínez Ángeles, Manel; CORTELLA, Giovanni; Llopis, Rodrigo Universidad Politécnica de Cartagena (2022)Prof. Baomin Dai suggested in 2018 that the use of zeotropic mixtures with high glide could provide energy improvements as refrigerants in dedicated mechanical subcooling systems for CO2 plants due to matching of temperature ... -
Experimental evaluation of alternative CO2-based blends for transcritical refrigeration systems
Vidan-Falomir, Francisco; Larrondo Sancho, Rafael; Sánchez García-Vacas, Daniel; Martinez-Angeles, Manel E.; Calleja-Anta, Daniel; Nebot-Andres, Laura; Llopis, Rodrigo; Cabello López, Ramón International Institute of Refrigeration (IIR) (2023-08-21)This work presents two refrigerant CO2 blends with R32 and R1270 designed with a theoretically nonflammability and a GWP below 150. Both mixtures were tested in a small-capacity vapour compression system with and without ... -
Experimental evaluation of different refrigeration system configurations using CO2-based blends as refrigerants
Sicco, Emanuele; Martínez Angeles, Manel Enric; Toffoletti, Gabriele; Nebot-Andres, Laura; Sánchez García-Vacas, Daniel; CORTELLA, Giovanni; Llopis, Rodrigo International Institute of Refrigeration (IIR) (2023-08)Recently, blends created by mixing CO2 with another fluid with a higher critical temperature are being considered, to allow subcritical operation at high outdoor temperature, thus increasing the COP. The goal of this ... -
Mejora energética de sistemas de subenfriamiento mecánico en plantas de refrigeración con CO2
Nebot Andrés, Laura; Calleja-Anta, Daniel; Sánchez García-Vacas, Daniel; Cabello López, Ramón; Martínez Ángeles, Manel; Llopis, Rodrigo Universidad Politécnica de Cartagena (2022)El subenfriamiento se está popularizando en los últimos años como solución de mejora energética de los sistemas de refrigeración con CO2. En concreto, los sistemas de subenfriamiento mecánico muestran un potencial de mejora ... -
Modelling and experimental validation of a CO2 concentric tube evaporator using heat transfer correlations and flow pattern maps
Sáez Pastor, Alejandro; Patiño Pérez, Jorge; Prades Martell, Lledó; Monrós Andreu, Guillem; Marín, Enrique; Sánchez García-Vacas, Daniel; Llopis, Rodrigo; Cabello López, Ramón Universidad Politécnica de Cartagena (2022)Las regulaciones en materia de medio ambiente adoptan medidas cada vez más restrictas en aras de reducir la contaminación medioambiental, principalmente regulan dos aspectos en el mundo de la refrigeración, la carga ...
