ANN Modeling to Analyze the R404A Replacement with the Low GWP Alternative R449A in an Indirect Supermarket Refrigeration System
Ghanbarpour, Morteza; Mota-Babiloni, Adrián; Makhnatch, Pavel; Badran, Bassam E.; Rogstam, Jörgen; Khodabandeh, Rahmatollah MDPI (2021-11-30)Artificial neural networks (ANNs) have been considered for assessing the potential of low GWP refrigerants in experimental setups. In this study, the capability of using R449A as a lower GWP replacement of R404A in ... -
Geothermal storage integration into a supermarket’s CO2 refrigeration system
Karampour, Mazyar; Mateu-Royo, Carlos; Rogstam, Jörgen; Sawalha, Samer Elsevier (2019-05-23)This paper investigates the integration of geothermal storage into state-of-the-art CO2 trans-critical booster systems. The objective is to evaluate the impact of this integration on energy efficiency. Three scenarios of ... -
Retrofit of lower GWP alternative R449A into an existing R404A indirect supermarket refrigeration system
Makhnatch, Pavel; Mota-Babiloni, Adrián; Rogstam, Jörgen; Khodabandeh, Rahmatollah Elsevier (2017-04)R404A is going to be phased out from most of the commercial refrigeration systems due to its high GWP value of 3943. R449A (GWP of 1282) has been proposed to replace R404A with only minor system modifications in supermarkets. ... -
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 ...
