Computational tool for experimental refrigeration system analysis using spreadsheets

Mendoza Miranda, Juan Manuel; Belman Flores, Juan Manuel; Gallegos Muñoz, Armando; Mota Babiloni, Adrián; Navarro Esbri, Joaquin (Federación de Asociaciones de Ingenieros Industriales de España (FAIIE), 2014-12)

[EN] 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. ...
Evaluación energética de los refrigerantes R1234yf y R152a como alternativa al R134a en sistemas de refrigeración

Mendoza Miranda, Juan Manuel; Navarro Esbri, Joaquin; Mota Babiloni, Adrián; Belman Flores, Juan Manuel; Rubio Arana, José Cuauhtémoc; Peris Pérez, Bernardo; Molés Ribera, Francisco (Universidad Nacional de Educación a Distancia (UNED), 2013-10)

[EN] This paper presents a theoretical performance of R1234yf and R152a as possible replacements of R134a in refrigeration systems. The refrigeration system performance using R134a, R1234yf and R152a was carried out for ...
Evaluation of R448A and R450A as Low-GWP alternatives for R404A and R134a using a micro-fin tubes evaporator model

Mendoza Miranda, Juan Manuel; Mota-Babiloni, Adrián; Navarro Esbri, Joaquin (Elsevier, 2016-04-05)

[EN] When retrofitting new refrigerants in an existing vapour compression system, their adaptation to the heat exchangers is a major concern. R450A and R448A are commercial non-flammable mixtures with low GWP developed to ...
Experimental analysis of R1234yf as a drop-in replacement for R134a in a vapor compression system

Navarro Esbri, Joaquin; Mendoza Miranda, Juan Manuel; Mota Babiloni, Adrián; Barragán Cervera, Ángel; Belman Flores, Juan Manuel (Elsevier, 2013-05)

[EN] This paper presents an experimental analysis of a vapor compression system using R1234yf as a drop-in replacement for R134a. In this work, we compare the energy performance of both refrigerants, R134a and R1234yf, ...
Shell-and-tube evaporator model performance with different two-phase flow heat transfer correlations. Experimental analysis using R134a and R1234yf

Navarro-Esbrí, J.; Molés, Francisco; Peris, Bernardo; Barragan-Cervera, Angel; Mendoza-Miranda, Juan Manuel; Mota-Babiloni, Adrián; Belman Flores, Juan Manuel (Elsevier, 2014)

[EN] This work presents a model of a shell-and-tube evaporator using R1234yf and R134a as working fluids. The model uses the effectiveness-NTU method to predict the evaporation pressure and the refrigerant and secondary ...
