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 ... -
Design of an environmentally friendly refrigeration laboratory based on cooling capacity calculation for graduate students
Mota-Babiloni, Adrián; Makhnatch, Pavel; Navarro-Esbrí, Joaquín; Moles, Fran; Khodabandeh, Rahmatollah Ahmad Ibrahim (2018)Lower global warming potential (GWP) refrigerants must be used in refrigeration education to integrate the environmentally responsible engineering principles in class. However, most of the refrigeration educational ... -
Experimental assessment of R134a and its lower GWP alternative R513A
Mota-Babiloni, Adrián; Makhnatch, Pavel; Khodabandeh, Rahmatollah; Navarro-Esbrí, Joaquín Elsevier (2017-02)Lower GWP refrigerants are essential to mitigate the impact of refrigeration systems on climate change. HFO/HFC mixtures are currently considered to replace HFCs in refrigeration and air conditioning systems. The aim of ... -
Experimental study of R450A drop-in performance in an R134a small capacity refrigeration unit
Makhnatch, Pavel; Mota-Babiloni, Adrián; Khodabandeh, Rahmatollah Elsevier (2017-08)The Kigali amendment to the Montreal Protocol has highlighted the hydrofluorocarbons (HFCs) phase out as a priority to reduce the future global mean temperature increase. R134a is the most abundant HFC in the atmosphere ... -
R450A and R513A as lower GWP mixtures for high ambient temperature countries: Experimental comparison with R134a
Makhnatch, Pavel; Mota-Babiloni, Adrián; López-Belchí, Alejandro; Khodabandeh, Rahmatollah Elsevier (2019-01-01)In recognition of the impact of the refrigeration sector on climate change, global commitments are achieved to replace hydrofluorocarbon substances with more planet-friendly alternatives. In this regard, countries with ... -
Recent investigations in HFCs substitution with lower GWP synthetic alternatives: Focus on energetic performance and environmental impact
Mota-Babiloni, Adrián; Makhnatch, Pavel; Khodabandeh, Rahmatollah Elsevier (2017-10)egulation (EU) No. 517/2014 (F-gas Regulation) controls the use of HFCs in several applications. This paper reviews the recent investigations performed because of F-gas Regulation, with focus on lower global warming potential ... -
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. ... -
Theoretical Global Warming Impact Evaluation of Medium and High Temperature Heat Pumps Using Low GWP Refrigerants
Ghanbarpour, Morteza; Mota-Babiloni, Adrián; Badran, Bassam E.; Khodabandeh, Rahmatollah MDPI (2021-08-01)This study provides a global warming impact analysis of environmentally friendly refrigerants used as replacements for R134a and R245fa. R290, R1234yf, R1234ze(E), R513A and R450A are considered as refrigerants to replace ...
