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 ... -
Optimal refrigerant mixture in single-stage high-temperature heat pumps based on a multiparameter evaluation
Fernández-Moreno, Adrián; Mota-Babiloni, Adrián; Giménez-Prades, Pau; Navarro-Esbrí, Joaquín Elsevier Ltd (2022-01-25)High-temperature heat pumps (HTHPs) are compression systems that convert residual heat to high-grade heat used in several industrial applications. Refrigerants for HTHPs are still not explored, and most studies consider ... -
Semi-empirical analysis of HFC supermarket refrigeration retrofit with advanced configurations from energy, environmental, and economic perspectives
Mota-Babiloni, Adrián; Giménez-Prades, Pau; Makhnatch, Pavel; Rogstam, Jörgen; Fernández-Moreno, Adrián; Navarro-Esbrí, Joaquín Elsevier B.V. (2022-02-23)F-gas phase-down schedules will remove most of the HFCs (hydrofluorocarbons) used in refrigeration systems in the short term. Besides refrigerant substitution, configuration modifications can be considered in existing ... -
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. ...
