Advanced two-stage cascade configurations for energy-efficient –80 °C refrigeration
Udroiu, Cosmin-Mihai; Mota-Babiloni, Adrián; Navarro-Esbrí, Joaquín Elsevier (2022-06-24)In response to the COVID-19 pandemic, some vaccines have been developed requiring ultralow-temperature refrigeration, and the number of these freezers has been increased worldwide. Ultralow-temperature refrigeration operates ... -
Energy efficient technologies for ultra-low temperature refrigeration
Udroiu, Cosmin-Mihai; Mota-Babiloni, Adrián; Espinós Estévez, Carla; Navarro-Esbrí, Joaquín Springer (2022)Sustainable transition is ongoing in many refrigeration and heat pump applications following what is established in national and international regulations. However, many of them have not controlled ultra-low temperature ... -
Influence of subcooling in R-449A supermarket refrigeration system and screening of refrigerant mixtures for its energetic and environmental improvement
Giménez-Prades, Pau; Navarro-Esbrí, Joaquín; Udroiu, Cosmin-Mihai; Mota-Babiloni, Adrián Elsevier (2024-01-10)Current demands of the cooling sector are focused on using refrigerants with a low Global Warming Potential (GWP) and increasing energy efficiency in vapour compression installations. The main objectives of this paperwork ... -
Influence of subcooling in R449A supermarket low-temperature refrigeration circuit using medium temperature cooling load
Mota-Babiloni, Adrián; Giménez-Prades, Pau; Udroiu, Cosmin-Mihai; Barragán Cervera, Angel; Navarro-Esbrí, Joaquín Institut International du Froid (2023-04-05)This work studies the impact of subcooling in supermarket refrigeration systems with medium and low-temperature requierementsbased on a vapor compression single-stage with a subcooler. -
Ternary refrigerant blends for ultra-low temperature refrigeration
Mota-Babiloni, Adrián; Fernández-Moreno, Adrián; Giménez-Prades, Pau; Udroiu, Cosmin-Mihai; Navarro-Esbrí, Joaquín Elsevier (2023)The absence of GWP limitation for refrigerants operating in vapour compression systems with a target temperature below –50 ◦C has caused slower market development. Therefore, while typical refrigeration applications have ... -
Thermodynamic evaluation of CO2 for ultra-low temperature refrigeration
Udroiu, Cosmin-Mihai; Mota-Babiloni, Adrián; Giménez-Prades, Pau; Barragán Cervera, Angel; Navarro-Esbrí, Joaquín Elsevier (2023-09-12)Carbon dioxide (CO2, R744) is the only refrigerant in the safest class by the ASHRAE 34 Standard in the group of natural refrigerants, with zero ozone depletion potential and a global warming potential of 1. It has been ... -
Towards sustainable process heating at 250 °C: Modeling and optimization of an R1336mzz(Z) transcritical High-Temperature heat pump
Udroiu, Cosmin-Mihai; Navarro-Esbrí, Joaquín; Giménez-Prades, Pau; Mota-Babiloni, Adrián Elsevier (2024-04-01)Fossil fuel boilers typically produce high-temperature process heating due to the impossibility of current renewable technologies. Vapour compression heat pump systems have been proposed up to 200 °C with subcritical cycles. ...
