Publicaciones DYNA (2014-12)This paper presents a spreadsheet application for data filtering and energy analysis, which has applications in research and experimental evaluation of the energetic performance of alternative refrigerants. Experimental ... -
Experimental drop-in replacement of R404A for warm countries using the low GWP mixtures R454C and R455A
Elsevier (2018-05)This article presents an analysis of the feasibility of R454C and R455A, two new low global warming potential (GWP of 148) refrigerants, in vapor compression refrigeration systems as alternatives to R404A for warm countries. ... -
Experimental study of R450A drop-in performance in an R134a small capacity refrigeration unit
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 ... -
Modeling and multi-objective optimization of an R450A vapor compression refrigeration system
Elsevier (2019-01-05)The main objective of this work is to comprehensively investigate R450A behavior in refrigeration systems and subsequently optimize the main operating variables for the first time to reach the maximum performance. For this ... -
Using ANNs to approach to the energy performance for a small refrigeration system working with R134a and two alternative lower GWP mixtures
Elsevier (2017)In this paper, an artificial neural network application to model a small refrigeration system is presented. The main objective of this study is an energy comparison of three refrigerants: R134a, R450A and R513A. The ... -
Variable speed liquid chiller drop-in modeling for predicting energy performance of R1234yf as low-GWP refrigerant
Elsevier (2018-07)This paper presents a model for a variable-speed liquid chiller integrating a compressor model based on Buckingham π-theorem to accurately predict the system performance when R134a is replaced with R1234yf, using a wide ...
